ABSTRACT

The role of metaphors in B2C ecommerce user interface design, why it is considered so important and how they could be classified is discussed in this paper. ~Jser interface design requires designing metaphors according to the essentials terms and concepts and images representing data, tasks roles, organizations and people. This study begins with an overview of the nature of metaphors from its humble beginning as a literary device to its present status as fundamental aspect of human intelligence. The aim of this study is to classify the user interface metaphors in B2C ecommerce website for ease of understanding them. As a process, series of websites are taken as examples and analyzed of the use of user interface metaphors and the frequency of metaphor usage. The research methods include analyzing the

twenty B2C ecommerce websites published in 2000, for the extent of metaphor usage, through analysis matrix and graphs. This research classifies the user interface metaphors into two broad categories; organizational metaphors and visual metaphors. Organizational metaphors are further classified as structural and navigational metaphors and visual metaphors are classified as symbolic metaphors and personalization. The outcome of this study would aid researchers and designers in creating ecommerce websites. 1

CHAPTER 1

INTRODUCTION

The Internet plays a vital role in all aspects of today. From its creation in 1983 it grew rapidly beyond its largely academic origin, into an increasingly commercial and popular medium. By the mid-1990's the Internet connected millions of computers and by the late

1990's the Internet was flourishing.l

According to Merriam Webster's ~'ollegiate Dictionary, the word "internet" means, "an electronic communications network that connects computer networks and organizational computer facilities around the world."2 Yet another definition given by Anita Rosen in her book, 7~he E-Commerce Question and Answer Book, defines Internet as "a facility, which provides one with the technical infrastructure to enable an online presence." She adds that the

Internet is a "technical structure" enabling people around the world to gain access to the

World Wide Web (WWW). Elaborating further, she says that the Internet is a global network, which is made up of smaller networks, linking millions of computers around the world, through telecommunication infrastructure.3

The exponential growth of Internet and the evolution of technological capabilities, all transformed the way business is being conducted. This transformation of the way goods and services of a company is delivered and received on the web is called ecommerce. With

Internet service, browser and a computer, millions of World Wide Web customers today, can

~ Cerf Leiner, Kahn Clark, Lynch Kleinrock, Roberts Postel, Wolff. "A brief History of the Internet" http://www.isoc.org/internet/history/brief/html (accessed Oct S, 2001). ` Merrian Webster Dictionary. p 612. 2 go online to buy and sell goods and services at any time and at any place. The success of electronic commerce is obvious on the value of online transaction taking place ranging from billions of dollars today.4

To enable effective. navigation on ecommerce websites, interface design plays a very important role. Studies have proved that the use of metaphors is effective in user interface design if utilized well. In its simplicity, user interface can be referred to as, a method and device that is used to accommodate interaction between machines and the human beings who use them.5 On the other hand a metaphor can be defined as "An implied analogy in which one thing is compared or identified with another dissimilar thing. For example, a feeling that is described in terms of "butterflies in the stomach," a "heart beating like a drum," or "just going blank. " 6

The three concepts, ecommerce, user interface and metaphors that contribute to form an important part of ecommerce website form the basis of this study, too. Here an attempt is made to analyze the role of these three concepts in a B2C ecommerce websites design.

Business processes govern relationships. As far as design of an e-business website is concerned, a study shows that unsuccessful online business often have websites that are equal

3 Rosen, p 2. a Deborah Lynn Harrington, Electronic commerce, The technological transformation of business http://www.ala.org/acrUresoct99.html (October 1999} (accessed Nov 2001) User Interface Design, http://cfg.cit.cornell.edu/cfg/design/bkg.html (accessed Nov 2001) 6 Cei Davis, METAPHORS, SYMBOLS AND RELATED CONCEPTS: Figurative Language Examined, http://www.devco.demon.co.uk/definitions.html (November 1997) (accessed Nov 2001) 3

to those of successful ones, in terms of design, price, ease of navigation and speed. But the

real difference Iles in the following:

• Ecommerce is about commerce, not just "information" or "sales" or "hits".

• Commerce is built on interaction. It is a dialogue of conversation with possibilities

and commitments. The richer the interaction the more the possibilities and greater the

scope of commitments.

• Value based interactions become relationships, which means these go beyond the

transaction. ~

This however does not mean that the design of the web site does not play an important role.

In fact, the design is the face value of an e-commerce business. When the company projects its profile, creating a first impression on its end customers, this face value carries more weight in attracting the customers and browsers through the products and services, even before the actual transaction.

This sophisticated setup of ecommerce and its tremendous growth, made researchers wonder what the design factors would be, that would have contributed to this growth? In the process of this examination, user interface emerged as a very important element, which enables navigation within the site effective. Metaphors on websites always attracted researchers' attention and in the process of narrowing the research, it was decided to explore the user interface metaphors in B2C ecommerce websites. 4

BZC is the retailing part of ecommerce on the Internet. It is often contrasted to B2B or

business-to-business. Here, B2C is chosen over B2B because B2C companies have a direct

contact with their end customers. In short, online companies conducting business have a

website which the customers use and therefore analyzing the pattern of usage of user

interface metaphors on these websites is possible. Another reason to choose B2C companies

is that business-to-business (B2B) companies use the extranet. An extranet provides a

business with an Internet site that is accessible to a select group of people. It also provides

the business with the ability to create applications that associates and customers can access,

but these are not accessible by the general public. Extranets can use encryption and password

protection to secure access to the site. For business- to business transactions, extranets enable

secure electronic commerce. Also the extranet can automate information sharing by

providing access to specific information and controlled access to internal database.8

Research of B2B User Interface Metaphors of companies would be impossible, as the

statistics on the extranet are highly confidential. If exposed, the companies would reveal the

factors of success and deficiencies of their business, which could prove critical.

The literature review gives an overview of three main concepts; e-commerce, metaphors and user interface. To validate the thesis, the methodology is based on the existing classification structure of user interface metaphors found in information architecture and multimedia and an attempt is made to apply a similar structure to B2C ecommerce websites. Appropriate examples would be sited and discussed in detail, to give a vivid clear picture. Therefore, this

~ Keen, McDonald, pp xiv. g Rosen, pp 11. S thesis attempts to analyze and categorize the various user interface metaphors seen on B2C ecommerce websites into major classif cations explaining, its significance and role in the website.

On doing so, several question come to mind, which will also be discussed. These are as follows:

1. How are user interface metaphors classified on B2C ecommerce websites?

2. How this classification is justified as an appropriate one?

3. What happens when the metaphors are overused?

4. V~hat are the possibilities of replacing the old metaphors with new ones? 6

CHAPTER 2

METHODOLOGY

The purpose of the study is to classify the user interface metaphors in B2C ecommerce website design, which could be applied by researchers, designers and web developers to design new ecommerce websites. This methodology is a result of an in-depth analysis of the prior literature within the fields; ecommerce, user interface design and metaphors. This chapter provides a description of the sample of research methodology, process of the design of the study, matrix form and statistical techniques used for analysis.

Process

Based on the literature, and the rating list provided in the Next Card,' of the top twenty existing B2C ecommerce websites, all twenty websites were chosen for this study and were analyzed for their usage of user interface metaphors. The analysis showed similar metaphors being used in all these websites, forming a recognizable pattern. To recognize and further understand, the user interface metaphors in these sites, an attempt has been made to classify them in three major categories, each category having subsidiary classifications within them.

Also the metaphor classifications are supported by examples, found in researched websites.

To anchor these findings and to enhance better understanding, a matrix is created to show the existence of different classification of user interface metaphors in the analyzed websites.

Since the subject matter is grounded in theory, the dimensions of the matrix are apparently,

B2C ecommerce websites on the `X' axis and the different categories of user interface

' Next Card E-Commerce Index, Accessed Nov.2001. Dated July 2001 (www.nextcard.com/indexes/july_index_movers08_20_Ol.html ) metaphors seen in these websites on the `Y' axis.

The division of metaphors found in the B2C ecommerce websites is not a rhetorical suggestion. It is based on the classification of metaphors found in information architecture and multimedia. A similar attempt is made to analyze and classify the user interface metaphors in the B2C ecommerce website. To make this analysis practically achievable, the top twenty B2C ecommerce websites were taken into consideration and analyzed for the usage of user interface metaphors.

As a next step, the extent of the usage of the three major classifications of user interface metaphors is calculated using the analysis matrix, which shows how many out of the top twenty B2C websites use .these metaphors and the results of this usage are graphically presented for better understanding. Also, a comparative study of the top ten to the bottom ten

B2C websites is done, showing the extent of usage of the classified metaphors.

The next step is to evaluate the reliability of the classification of user interface metaphors.

Three users, who use the Internet and shopped online, were selected randomly. They are briefed about the various concepts of the study and explained in depth, the analysis part where the classifications of metaphors are done. Then, they are allowed to ask question and clarify any further questions. As the next step of the reliability test, they are given a questionnaire, to answer based on the details of the study provided to them. The data thus collected is used to see the reliability of the study. 8

Measuring the Reliability of the Research

It is very important to measure the reliability of the research as a next step. Validity of research is measured by two methods- the internal and external methods. The internal method requires preciseness of study in a particular situation and a validity of this kind of study is only in researched situations. On the other hand, external validity system concerns the

`generalizability' of the finding from the research. This particular type of validity asks whether the conclusion from particular study can be applied to other people and other contexts. The external validity study is used, as methods to measure the validity. The conclusion of the study drawn is not limited to particular people or context studied. However the external nature of the study is related to these factors:

1. How the people studied were selected

2. Whether the procedures used mirror real life, called ecological validity and

3. The need to replace research findings.

The reason why the external validity method is chosen is the number of artifacts, in this case websites, taken into consideration for the study is very limited. Also the study is general, and its reliability can be tested without much restriction in several other circumstances and situations. In this research, the external validity method was used to measure the reliability of the classification of metaphors in the B2C websites.

Process of Reliability

However, to ensure the reliability of the classifications of user interface metaphors in B2C ecommerce websites, a method to measure its reliability or consistency is conducted using 9 three users randomly picked who use the Internet often and also have online buying experience. As step one; users are explained the classification of the categories of metaphors, with suitable examples. Step two; their questions about the classif cations were clarified for better understanding. Step three; users were asked to identify the metaphors given to them.

They were placed in real situation sitting in front of the website mentioned in the questionnaire. They were asked to classify with the help of explanation they were given on the classification of metaphors earlier. The result of testing; they are studied on their views of acceptance of the metaphorical classifications.

The data thus collected are worthwhile only if recorded in an accurate and unbiased way. The more close the data reflects the concept researched, the more reliable the measurement technique is. The more reliable the measurement is the more dependable it becomes as it

Leads to similar outcomes when applied to different contexts2.

The paper will also discuss the need for new user interface metaphor, the outcome of introducing new ones and the results of using the existing user interface metaphors. This part of the paper would be an argument based on literature and my scrutiny of the analyzed websites. Finally, the study will be concluded with limitations and scope for future research based on this subject.

CHAPTER 3

LITERATURE REVIEW

In order to understand further in detail what is being talked about, it is important to

understand the various terminologies and their concepts, used in this research; like

ecommerce, user interface and metaphors. This chapter introduces the major topics related to

this research and the topics are discussed based on the application to this research. Finally the

literature review is concluded with a summary.

Ecommerce

Ecommerce can be broadly defined as conducting commercial business activities among

interested partners using computer networks. Here, interested partners would include

customers, suppliers, banks, transport carriers, competitors, employees and other business

agencies that interact with the organization.l

Ecommerce is first and foremost about commerce. Commerce focuses on relationships,

involving the exchanging of values between two or more parties. Such relationships are

critical in ecommerce to overcome the high cost of acquisition, which can erase the

company's profit potential. In this context, relationships mean more than j ust strong call-

centers. In other words, it means designing and operating business from the customer's

perspective and re-organizing all those aspects of the business operation after the customer.

This operation includes processes such as shipping that were traditionally viewed as being in

' Rosen, p 2 12

the back office. Therefore, ecommerce's success rests on building relationships and repeat

business.2

In defining the Internet with reference to ecommerce, the Internet is one that gives the ability

to provide and present, potential customers, prospects and business partners, easy access to

information about one's company and products, from their home or offices. Once the web

presence is obtained and its value realized one would be in a position to offer other goods

and services.3 To understand ecommerce clearly, it is important to first see the development

of Internet and websites.

Generations of websites

As the use of the Internet became more sophisticated, websites also changed to meet new

needs. These changes are categorized in generations of websites. Websites in the Internet can

be divided as first, second, third and fourth generation web sites. Generation one websites

created simple brochures that were displayed online as websites. As the Internet became

more sophisticated, many companies became aware of the emergence of second-generation

web sites.11~Ianagement-established web sites that reflected corporate issues: investor

relations, company mission statements and messages from the president come under this category. The. generation three websites were driving business-to-business (B2B) and business-to-consumer (B2C) transactions, as the companies understood the potential of the

Internet by then. Therefore, at this point it was important for the websites to become simpler, faster and more focused on specific needs of people visiting the site. Generation four website

2 Keen, McDonald, pp 33-35. 13 is the future of the Internet. It is also important to note that physically, generation four and generation three websites resemble each other. The difference between the two is predominantly behind the scenes. The former are dynamically created and more tightly integrated into the operation of the company than the latter.4 It could be concluded that generation three websites brought in B2B and B2C commerce. It is now important to understand ecommerce and its significance.

Ecommerce is all about activities between two trading partner. These activities are divided into two types, information communication and physical transaction. Surprisingly, the former is more concerned with the electronic commerce. Therefore, electronic commerce focuses on providing electronic solution to all activities of information communication between two parties. This electronic solution has brought a radical change in trading information between two parties, switching from paper to other media and computer based communication.

Therefore, ecommerce on the broader sense can be considered as a business methodology that facilitates the organizations to improve customer service, reduce cost, improve quality and thereby create a competitive advantage for the organization.5 All this is possible because ecommerce eliminates the role of middlemen and makes transaction between the business and the end customers6.

Ecommerce Classification

Ecommerce can be classified into five broad classifications:

3 Rosen, pp 1-3. a Neiland, pp 27-31. 5 Rosen, p 3 14

• Business to End Consumers (B2C— End Consumer Commerce).

• Business to Business (B2B— Inter-Organizational Commerce or Extranets).

• Consumer to Consumer (C2C~ommunities).

• Consumer to Business (C2B)

• Business within Business (Infra-Organizational commerce or Intranet).

At the turn of the twenty-first century, the global market changed the fabric of society at a rate never experienced before. The Internet in particular has re-drawn economic boundaries of countries. Today, to be competitive in the market place, companies need to expand commercial activities beyond national borders. The global network of electronic infrastructure has played a significant role in this expansion along with the customer demand and technology. Customers are not only adapting the new technologies, they are demanding more and more global competition. Therefore, it could be argued that electronic commerce is the most important economic trend of our time. The Internet is already playing a significant role in determining corporate strategy and in creating values.$

Electronic commerce covers the range of online business activities for products and services, both businesses-to business and business-to-consumers, through the Internet. This section is divided as follows,

• Online shopping- the scope of information and activities that provides the customers

with the information they need to conduct the business with the retailers and make an

6 Lecture, Kumar. Aug 8, 2001. ' Ibid. Aug 8, 2001 15

informed buying decision.

• Online purchasing- the technology infrastructure for the exchange of data and the

purchase of a product over the Internet.9

The Internet thus brings the retailer and the customers or two business parties closer to each other, by accessing the information directly. Factors like the size and location of the company does not matter in such cases, though they once used to be important factors in the establishment and success of the business. On the other hand ecommerce enables direct access to the customer responses and feedback when new marketing and pricing programs are published on the retailer's web site. l o

Ecommerce also has contributed to the advancement of technology due to growing development. It is changing the way people work, as it is bringing in the digitization, globalization, mobility and immediacy, all of which are based on the development of the

Internet.l 1 Case studies also show that there are web sites and companies who do online business acting as middlemen. One such example is the auction site e-bay. The process of becoming closer to the customer by eliminating the middlemen is called disintermediation.12

Customer's Expectation

Customers are the final judges of a business site's success. If the site meets the needs of the

g Ibid. Aug 8, 2001 9 Rosen, pp 5-6. 10 Rosen, p 10. " Rosen, p 10 12 Rosen, pp 12-14. 16 customers, providing them with the information they require in a simple, straightforward fashion, they will treat the business site as one of the primary sources for information products and services. The reasons for this are as follows.

• Online customers are more interested in a convenient buying experience than in a

visual stimulating site. The information should be focused on creating an experience

that is simple, easy and informative. Therefore, information pertinent to customers

should be placed front and center.

• Earlier in this paper various generation web sites were discussed and a conclusion

was made that generation three and four web sites made ecommerce transaction on

the web possible. This is because; they are virtually simple, fast, and easy to navigate

and are focused on specific needs of the person visiting the site.

• When developing the site, the business can spend thousands of dollars on aesthetics

and niceties. At the same time surveys show that customers are more interested in a

convenient buying experience, which would include rapid responses, quick

downloads, good organization, etc, than on appear.ances.13

A survey done by Binary Compass Enterprise shows that when customers buy online, web site aesthetics are the least important aspect of the experience. Customers are interested in the ease of using ,the site. Therefore a simple site with clear accessible information is more effective than a site with beautiful graphics, poor navigation and little relevant information.

At the same time the look the company projects itself is very important to the company, as it

13 Kumar, August 8, 2001. 17 reflects the image of the company but not to the customers.1 `~

Branding

A successful site reflects the company. It reinforces the company's branding, provides easy navigation and a straightforward access to information. The Look of the site is important to the company, as branding is the visual imagery that the company applies in all its publishing and applied design. Branding visually defines the company and business. Therefore, the site should reflect the current branding. The customer need not read the label, but only see the brand image to know that a product came from the particular brand. To create this strong branding campaign the company has to apply the brand (visual image) to all visual aspects of the products including the web site. Incorporating the current branding elements, including the color scheme, further emphasizes the branding.l s

Shift from Market Place to Market Space

Also due to the growing Internet Technology (IT), there is a shift of business from market place to the market space. Market place is the physical world of resources that create products and service and market space is the virtual world of information that complimentsl substitutes the physical world. Technology has grown tremendously and this growth has made managing the market space effective and efficient. At the same time the cost factor is also a very important consideration in the shift from market place to market space. IT reduces the cost of searching for suppliers, exchanging and processing information and thereby

14 Rosen, p lo. is Knapp, pps-6 18 reducing the coordination cost. It also increases the information availability for facilitating better contracting and performance monitoring of partners in a trading relationship and there by reduces operation risks. To add to all this is the ease of buying anything online with one click and receiving it at your doorstep.16

Web Statistics

It is essential that the company maintain a statistic of the various activities of their customers, tracked on their visit of the site. Statistic reports can be maintained to identify popular paths and entry points. Bermuda triangle could be found in the site- a page people enter, never to be heard from again. It is also worthwhile to spend the time wading through all the data one gets from the current site-analysis programs.

Search Engines

The site search engine is another important for fast and easy accessibility of information. It would be a good idea to save the words people enter into the site search engine. From this information it would be helpful to update the site using popular key words people are searching for. Sales from the online purchasing service can be used to gather information on customer buying pattern. This information is very important to the development and success of the company. l ~

Ecommerce is growing fast. Despite a continued sluggish economy, business research firms

16 Kumar. (Accessed Oct 15, 2001). 19 are predicting that there would be a continuous growth in B2C market. According to Zona

Research, it estimated ecommerce would grow to $100 billion USD (US dollars) by the year

2000 and CNNfn predicted ecommerce would hit 400 billion USD in 2002, 750 billion in the year 2003 and 833 billion in the year 2005. The number of people buying online were expected to rise from 18 million in December 1997 to 128 million in 2002. Accordingly, the total value of goods and services traded between companies will reach from $8 billion in

1997 to $327 billion in the year 2002.18 There will also be a change in the revenues of B2C companies in particular. Total B2C Revenues for US 1999 - 2005 (in USD billions) is listed 19 in Table 1.

Year 1999 2000 2001 2002 2003 2005

Units in USD 75 150 250 400 750 833 Billions

It is also predicted that growth in ecommerce will slow down in 2001and analysts predict online sales top increase by 5 7 percent in the year 2000. An upcoming report from e-Market shows that Internet sales will be worth USD 65.9 billion in the year 2001, compared to the

USD 42 billion of 2000. It also predicts that sales for the first quarter of 2001 will reach USD

1 ~ Miller, "Web Interface Design: Learning From Our Past". http://athos.rutgers.edu/~shklar/www4/rmiller/rhmpapr.html. October 2001 (Accessed January 2002) Electronic Commerce Data, http://www.internetsecure.com/reference/critical.html.(Accessed 16 August 2000) 19 «Fortune Magazine" Accessed 13 Sep 2001 http://www.epaynews.com/statistics/transactions.html#21 20

13.5 billion, which would be up to 8 percent in the fourth quarter of 2001. Over the same period last year, sales grew by 14 percent.

Another source predicts the following for the year 2001,

"As the ecommerce: B2C Report shows, the real opportunities for success are only now making themselves known. In fact, most signs indicate that this year's holiday season is going to be bigger than last year, According to the ecommerce: B2C Report, US online retail revenues wi11 to $37 billion this year, with nearly a third of that coming In the fourth quarter alone.»~o

Ecommerce has spread rapidly throughout the world by mean of Internet. The use of good visual quality and a well functioning site design can attracting and hold more customers and this will eventually result in an increase in ecommerce sales for that site. In a recent research conducted by Yankevich partners (2000), located on Nua dot net, consumers were less likely to leave sites that were well designed and easy to navigate. This implies that the design of an ecommerce sites maybe as important as its content, service and the product itself.

User Interface

The next important topic of this research is user interface. To understand user interface, this section analyzes the conventional user interface seen in computers. Then it would brief about the usability and its benefits in business and usability and its importance in the World Wide

Web.

User Interface Desi in a Computer Sys_ tem

User interface is that part of the computer system, where the human user interacts with the computer. As the user has no access to the interior components of the computer system except through the user interface, in the case of typical information systems and office systems, user interface includes the following,

• The computer hardware which the user can interact with, e.g., the keyboard, mouse,

screen, the off /on switch etc.

• The images that are to be seen on the screen, e.g. windows, menus, messages, help

screens etc.

• User documentations such as manuals and reference cards and

• Text based information.21

Since human interaction with the system is only through interface, usability plays a vital role in such interactions. In such cases, the better the usability the effective the interaction.

Therefore, usability can be described as "a concept, which is implicitly understood by most people as well all know what it is like to operate man made products, and find them more or less to use.22

User Interface and Usability

The purpose of the user interface is to make the computer system usable by the user.

Therefore, the most critical quality of the user interface is its usability. Usability includes both easy to learn and effective to use. Such user interfaces that are easy to learn and

21 Redmond —Pyle, pp 2. 22 "Usability" (Accessed 20 March 2001) http:/i www.states.fiiinclude/1-3.htm 22 effective to use are called "User-friendly" interfaces.23 Though called so, usability is a more appropriate term to use in describing the effectiveness of user interfaces. The concept of usability is an abstract one but not always vague. According to researchers, usability has four main aspects. These are effectiveness, learnability, flexibility and attitude.24 In a particular relevance as the web, with its variety of users world wide with their different needs and skills, teaching all the users use the site would be impossible. Therefore certain patterns of usability are followed, which the users are already aware of. In other words, it is like learning new tricks while still using some old ones. However, flexibility to these patterns can be applied, but a very small scale, to avoid confusion in the user. This would result in the positive attitude of the user towards the site. It is very important to note that the user on the web is looking at fast paced information. Several researches show that the user does not spend time in the site if the interface in the website is not effective. He simply switches to another site in search of the required information, products and services.2s

while performing the user tests the user's attitude towards the tasks in the system and the system on the whole is very closely monitored. The attitude of the user is very important, as an unfavorable attitude can make the user quit performing the task. The same attitude, when applied to web sites, which are not user friendly, the user switches to another web site.26

Though the other concepts are measured in the using the above mentioned two methods, flexibility is difficult to qualify and in practice it is not usually measured.

23 Redmond —Pyle, pp 3-7. 24 Redmond —Pyle, pp 3-4. 2s "Multimedia Design Guidelines" (Accessed 20 March 2001), http://www.ping.be/mmdesign/topic2f3.htm.) . 26 Neilson, "Usability Metrics" (January 21, 2001) (Accessed 14 September, 2001). 23

Usability is frequently achieved by bringing the interface closer to the user's way of thinking and working. This means adapting the system to the user rather than asking the user to adapt to the system. This is the point where the graphic user interface (GUI) designers and Graphic

User Interface prograr~imers play a very important role.27 Usability is the most important property of the user interface, at the same time it is important for the whole system, not just the user interface.

Usability and Business Benefit

Web and software usability (or the lacks of it) have enormous commercial significance.

Today the business climate is enormously competitive and most organizations are seeking to improve their business performance, for example by implementing quality management strategies. Effective usability can make an important contribution to meeting these business objectives. 28

In business, high learnability reduces training time and training costs, which are often a significant proportion of funds allotted by the businesses. In addition the immediate benefit is that, it can have wider commercial significance. The user's attitude to Graphic User Interface

(GUI) may seem soft and subjective, but has very serious implications. If people don't like the and the feel frustrated, tensed or anxious, rather than confident, effective and satisfied, then they will tend to avoid using the system or the website. This would deprive the business its opportunities in several aspects. http://useit.com/alertbox/20010121.html 27 Redmond —Pyle, pp3-4. Zs Redmond-Pyle, pp 4-5 24

The usability issues mentioned not only apply to human computer interface but also play a vital role in web interfaces. Thus, the above-mentioned points are adapted for web usability and therefore also used in ecommerce web site designs. The formula of success in the e- business stands upon the twin pillars of ecommerce and usability. An e-business strategy that unites these two concepts is sure to succeed. Usability is related to customer intelligence.29

Customer intelligence enables the company to have a better understanding of the customers

(i.e. lifetime, value demographics, profitability, preferences and tendencies etc.) so that they can effectively acquire, retain, service and/or cross-sell those customers to meet strategic business objectives. In essence, customer intelligence marries decision support with the database marketing and customer relationship management (C~) practices and products.3o

Usage of Graphics on the Website for Effective Usability

Graphic here can be defined as "The art or science of conveying information through the use of display media, such as graphs, letters, lines, drawings, logos, and pictures."31 Webopedia describes graphics especially computer graphics as, one that pertains to any computer device or program that makes a computer capable of displaying and manipulating pictures.32 They show how the product looks like and how to use the product. To use the graphic effectively unlike the second-generation websites where the graphics were large and took a long time to generate, the graphics should be small and standardized. This also means that many graphic seen in a webpage is also very distracting to the customer. The consequence, people get tired

`9 Rosen, p 10. 3o Eckerson, "Customer relationship Management" (Accessed 10 September, 2001) http://www.ncr.com/other/_industries/marrying/_ecommerce_cust_intell.asp Computer graphics on the web (Accessed 20 March 2001) http://rpi.eduldept/ilc/webclss/kairos/id.html 32 "Graphics" (Accessed 20 March 2001) http://www.webopedia.com/SHARED/search_action.asp 25

of the site and leave the site for another. Graphics should focus on helping the visitor get a

better idea of the company and its products. The viewer doesn't have the patience to wait for

large graphics to download.33 Also features like audio and video should be avoided that need

plug-ins to work. The reason, many companies don't allow the download on to their

corporate networks all customers are not aware of the download process.

When placing the information on the web, the company has to format the information

differently. Web is a fast media and the viewer is looking for quick accessibility of

information. To make this accessibility fast, the information is to be broken into paragraphs,

into bullet points, as people understand formats more. Using active words to describe, the

web services make readers sound like they are integrated with the business. It is very

important to keep in mind, things like proper grammar, correct spelling, and links that work, which form an essential part of a good copy.

Navigation

The web is all about navigation. The user navigates from one page to another by using the basic interface of click-on hypertexts, links, graphics (embedded links), etc, in order to move around the huge information space. Due to this vast space, navigation becomes a very important aspect in web pages. Also navigational interfaces help the users in answering three fundamental questions, where they are, where they have been and where they can go? These questions are not only related to the whole web, but are also related to the internal site

33 Ibid. (Accessed 20 March 2001) 26

34 structure, i.e. navigation within the site.

The elements of generation three-web sites, used currently, have proved success. These web

sites are created for the ease of the customers.

• These elements include, top and side navigation bars to simplify the information

access. The top navigation bar is used for high-level access to subjects, far example

products, support, online purchasing, corporate information, and site maps. Larger

companies or companies with diverse product lines will use the top of the page

navigation to provide the visitors with easy access to each of their products.

• On the side of the page, the navigation bar is used to access second-level subjects. A

visitor can then click on the names of the company's products, proceeding further to

click on the name of the product. The side navigation bar is then updated with

information specific to the product line.

• The center of the page is then available to display information on the product or the

subject.

• While the top navigation is constant throughout the website, the site navigation

changes according to where the visitor is on the site. This way the visitor can easily

access the subtopics from the side bar navigation and quickly move to major subjects

via the top navigation.35

34 Nielson, pp. 188-197. 3s Neilson, "Did Poor Usability Kill E-Commerce? (August 19, 2001) (Accessed Jan 2002) http://www.useit.com/alertbox/20010819.htm1 27

Finally, the users are not the webmaster of the commerce company they are visiting. It

cannot be assumed that they understand the navigation on the ecommerce site they are

visiting. Moreover, some users lack experience. Even if the site provides low cost high

quality products, users cannot buy or shop because they lack the capability to browse and

navigate in the site. Therefore, an ecommerce site should be rationale in using a common

interface design which will help users to navigate. According to researchers and designers,

amazon.com has maintained a high quality ecommerce website that is easy to use. Many

researchers also agree that amazon.com's interface design has set standards of efficiency.

Several other ecommerce stores have adapted this standard. It is also important to know that

the interface design generally is dependent on the products and its content. So an interface

that is best for amazon.com may not be the best solution for other online stores.

Theories of Metaphor that could be applied to Ecommerce Website Design

The next topic of this research is metaphors. In this subsection the study will give a detail account of what metaphors are, how they have been used rhetorically and a brief ng of their transformation graphically from computers to websites and specifically into ecommerce website design.

To understand metaphors, it is essential first to understand what is a metaphor? "A metaphor is a figurative speech, in which characteristics of one object or person are transferred to different, but analogous, object or person."36 Another definition says "the p resentation of one idea in terms of another, belonging to a different category, so that either the understanding of 28 the first idea is transformed, or so that from the fusion of the two ideas a new one could be created."37 In language, a metaphor is one of the tropes (twists and turn of language) of classical rhetoric.

The etymology of the word metaphor supports this idea of transformation, with "meta" meaning change and "phora" meaning motion. The meaning of motion referred here, is more of a semantic motion rather than a physical motion. These metaphors can be tested not grammatically but to see the quality of semantic motion. This theory was derived from

Aristotle's the Poetics in which Aristotle lists two types of meaning "ephiphor" and

"diaphor". "Ephiphor represents the transference of meaning, and diaphor, which uses juxtaposition and synthesis to create new meaning that involves semantic motion. Some of the most effective metaphors combine ephiphor and diaphor elements."38

The other key element of the metaphor is the tension between the primary and the secondary subject. A.I. Richards while developing an interaction theory of metaphor, coined the term

`tenor' to describe the primary subject and vehicle to describe the secondary subject, which is used to assert shared meaning. The gap between tenor and vehicle is the tension of the metaphor that has been lost, usually because of overuse. Since metaphors are intended to provide a unique perspective, overused metaphors are considered to be dead metaphors since they do not transform thought or add new insight.39

36 Clair, N.St. Robert, p 2. 37 Richard, Stephen. Barker, Philip. Banerji Ashok. Lamont. Manji, Karim, pp 5. 3s Forceville, pp 57. 39 Mayer, pp 131. 29

Max Black further developed I.A. Richard's interactive theory of metaphor, which states that the meaning of a metaphor is a result of the interaction of the subjects. The theory further elaborates that,

1. There are two subjects in a metaphor that go to form the primary and the secondary

element correspondingly.

2. Here, the secondary subject is regarded as a system rather than an individual thing.

3. The metaphorical utterance works when the primary subject is prof ected, a set of

associated inferences come to mind which also at the same time predict the secondary

subject.

4. When a metaphorical statement is made, the statement marks, selects, emphasizes,

suppresses, and organizes features of the primary subject by applying a if statement

that is related to a same or similar member of the secondary subject's implicative

complex.

5. When a metaphorical statement is made, two subjects interact in this particular way:

(a) the presence of the primary subject provokes _and urges to the hearer to select

some of the secondary subject's properties; and (b) invites him to construct a parallel

implication which is complex that can fit the primary subject; and (c) in turn

persuades parallel changes in the secondary subject.4o

Therefore, M~ Black emphasizes that the tenor (primary subject) and the vehicle (secondary subject) should be viewed as a system of meaning rather than individual elements. He also

ao Forceville, pp 57. 30 notes that the number of transferable characteristics that the vehicle can project upon the tenor determines the tension of the metaphor. Chosen characteristics can be determined by context, commonalities between subjects, cultural beliefs or other such criteria. With the transfer of too many features, the tension of the metaphor would be lost. However, if insufficient, more features are transferable. In such a case there would be no metaphor.

Black's ideas of systems of meaning, intend to encompass all these related elements of a metaphor. According to him, while- the interaction theory is generally based on verbal metaphors, it is directly related to the study of the interaction of images for nonverbal metaphors.

The above-mentioned theories can be applied to the metaphors in the ecommerce website. A few others have added, to the theory of Max Black. These theories focus on pictorial metaphors, as we would be discussing them in ecommerce websites that also have characteristics of usability. Though several theories have contributed to a more encompassing theory of pictorial metaphor, none of them provide an entirely satisfactory model. So the following conclusion can be made. According to the theory from various authors, Forceville, concluded as below,

"l .For pictorial metaphors to be called metaphorical, it is necessary that a `literal', or conventional. reading of the pictorial representation is felt either not to exhaust its meaning potential, or to yield an anomaly which is understood as an intentional violation of the norm rather than as an error. In as much as the former type does not force the viewer to perceive the pictorial representation as a metaphor, an approach that aims to contribute to a theory of pictorial metaphor had best focus, for the time being, on representations that on a conventional reading would be anomalous.

2. Considerable confusion has arisen from the fact that the word `metaphor has both been used in the broad sense in which it is more or less equivalent with `trope', and in a much more narrow sense in which it is used as one trope among many others (albeit possibly the queen of tropes). Any model of pictorial metaphor should specify 31

whether it attempts to do the former is faced with two daunting problems. In the first place, the number of verbal tropes is vast and known under partly overlapping names. Thus, one would have to find, or develop, a framework of verbal tropes that is sufficiently comprehensive and detailed both to accommodate a substantial number of them and to provide criteria to distinguish between them. Subsequently, one would have to find pictorial counterparts of these verbal tropes in such a way that these pictorial counterparts respect both intuitions about their verbal originals and maintain their distinction in the `translation' from word to image- and if this proves impossible, to adduce sound reasons why and how the framework of pictorial tropes differs from the corresponding verbal network. Since this is a task of intimidating proportions, it seems advisable, for the time being, to concentrate on `pictorial metaphor' in the narrow sense.

3. An account of pictorial metaphor should show an awareness that a metaphor has two distinctive terms, one the primary subject or tenor, the other the secondary subject or vehicle, which are usually, non-reversible. This entails that the transfer on mapping of features is from secondary subject (on) to primary subject and not vice versa. The account must further more indicate by what mechanisms the identities of primary subject and secondary subject are established.

4. For the identification of two terms of the metaphor, their labeling as primary subject and secondary subject, as well as for the interpretation of the metaphor, it is necessary to take various contextual levels in to consideration. These contextual levels are partly text —internal, partly text-external."41

Despite minor shortcomings, Max Black's interaction theory is regarded as the most satisfactory theory of metaphor till now developed. At the same time there is another part of metaphor, which is important to discuss- metaphor and truth.

Metaphor and Truth

According to Max Black, talking of the potential creativity of metaphor, warns on imposing

`true/false' tests on metaphors. The reason he gives is that a creation is never subject to the test: in as much as a metaphor is creative, it can be true or false as a painting or a poem can be. Lakeoff and Johnson agreed with Black Max's theory. This theory is very important to 32

ecommerce websites. At the same time Lakoff and Johnson argue that that the `truth' of

many metaphors can only be judged in the context of the reality defined by those very

metaphors. The mater of truth/ false becomes very important while dealing with conventional

metaphors. The reason for this is that conventional metaphors are so embedded in a language

that their metaphorcity is no longer recognized as much.42

Literal versus Figurative

Yet another part of the metaphor is the literal versus figurative, conventional versus

unexpected. Black has divided this section as the subdivision between frame and focus

presuppose the necessity of distinguishing between traditionally labeled the literal and

figurative in a metaphor. It has always been seen in a metaphor, that there is a tension

between this frame and focus, which has also been mentioned as the primary and secondary

element. However, Lakeoff and Johnson have concluded that the distinction between the

used and the unused part of a conceptual metaphor is a valuable one.43

Metaphors on the Web

Metaphors are ubiquitous in the user interfaces of today's websites. Web designers are

incorporating metaphors in a variety of websites. Technological advances have made more and more realistic depictions of these metaphors possible. However, technological feasibility does not ensure psychological utility.

41 Forceville, pp 64- 65 a2 Forceville, p 70. 43 Forceville, p 48. 33

This part of the paper summarized here is an initial attempt to understand how metaphors

make user's performance interesting and to identify the characteristics of these metaphors

that make them enhance the performance. Now metaphors are something that is over used in

web design. Maybe the greatest weakness of metaphors is that -they seem to entice designers

to be overly clever and push the site in the direction that seems fun and appropriate within

the metaphor but leaves users real goal behind.

Also a study of metaphorical use on websites show that 20.3% less mistakes have occurred

due to the use of metaphors in websites.44 On an average, users made fewer errors with the

metaphor interface than with the non-metaphor interface. In conclusion, the study cautions

the fact that all metaphors on the World Wide Web are not good, but the good ones facilitate

performance and the poor ones are no more effective than non metaphoric interfaces.

However, problems due to overused (dead metaphors) like the shopping cart, which has lost

part of its metaphorical quality, could not be avoided and replacing the old ones with

something new would create difficulties for the users to understand which would in turn

ultimately hinder effective communication. Therefore, overused metaphors are to be left as

they are and new metaphors are to be developed to project new concepts or ideas that have

not been used a lot on the World Wide Web.

To a great extent, the effects of metaphor on user's performance with the web are unknown.

Many guidelines encourage the use of visual and interface metaphors, though these visuals

~ Designing Web Usability Nielson, Jacob, p 79 34

are currently employed in the websites today. Beyond that, there is no research exploring

how to design the most effective metaphor. Little is known about the characteristics that

enhance the power and utility of visual metaphors.4s

The motivation for using metaphor in the design of websites is similar to the reasons

metaphors have long been popular in education. This directs to the old method, where it is

observed that giving students comparisons can help them learn. An analogy commonly used

in teaching about electricity is "Electricity is like water." The student is directed to imagine

that electricity flows like water. These types of comparisons are also used to project a

concept of a website design.46

Metaphors are seen widely on the World Wide Web. These metaphors on the World Wide

Web resume an interactive nature due to the effects of multimedia. Therefore, they are called multimedia-authoring metaphors.47 Multimedia authoring can be classified into five major divisions; scripting language metaphors slide show metaphors, iconic metaphors, navigational metaphors and cast/score/scripting metaphor.

Although the World Wide Web continues to utilize text, the primary tools of communication reside within its visual attributes. The web, through the presentation of the home page combines text with computer graphics in to one whole visual image. Text becomes part of the visual imagery often providing clarifications far interpretation of the individual images. Icons as Cooper, Alan, "The Myth Of Metaphor" http://www.cooper.com/articles/vbpj_myth of _metaphor.html. a6 Smilowitzn D Elissa "Do Metaphors Make Web Browsers Easier to Use?" http://www.baddesigns.com/mswebcnf.htm 35 or image maps take precedents within the presentation with accompanying text often serving as supplementary material (anchoring), which defines the visual image. Placement of the elements can be considered equally important thus re-enforcing the weight of visual communication. Therefore, the combination of text, images and their replacement allow a home page to be considered, while visual image comprised of various elements. Another form of visual metaphors on the web is through icons. Icons can be comprised of a single graphic symbol or a symbol combined with descriptive text. Each form can be considered as icon. Icons are used to define the meaning of what information will be found at the destination of a link and the type of interaction required of the user. As a result a metaphor is created as ability.

Within the medium of the World Wide Web, two distinct categories of metaphor are present.

External and internal metaphors serve to identify the characteristics of communication through the use of the Web. External metaphors are primarily linguistic metaphors used to publicly define the purpose, function and integration of the Web as a communication device.

Internal metaphors are those metaphors of a visual nature existing within a home page which determine the interaction, purpose and meaning of a website. Metaphors of this type could appear in the form of graphics, text, visual placement or a combination of all three.48

The evaluation of the phenomenon of the World Wide Web occurs through a relationship between external and internal metaphors. This relationship determines the level of interaction

47 Lawler, p 23. 4g Coblentz, Clayton "Metaphorically Interactive: The Rhetorical Examination of World Wide Web Home Pages" 36 or engagement with the content of a website. The longer the interaction with the website the more exposure to the ideology or influence of the website.49 The level of interaction is based upon how closely the external metaphors of defining Web communication correspond with the internal metaphors used to describe communication within a website. Publicly the Web has been defined as exhibiting certain characteristics. In order to clearly determine the effective use of internal metaphors within a website, the critic must first ascertain the primary goal or intention for the website's existence.

The V~WW by itself is a metaphor several connotations— a race, a tool, a game, a television and even a telephone.

Reasons to use Metaphors

Metaphors could be used for two reasons. The first reason is metaphors can provide a unifying framework for the design that would give a feel, more than a collection of individual items. The second reason is, metaphors can help learning by allowing users to draw upon the knowledge they already have about the reference system.so

A study of Clark and Clark in 1977 showed that memory of metaphors is better than memory of literal sentence.

"Traditional interpretation of figurative language suggests that literal meaning is processed first, and then rejected in favor of figurative interpretation."sl

49 Ib1C1 so Neilsen, p 180. 51 Forceville, p 35. 37

The idea that our lives are governed by figurative language and thought directly applies to the theories of metaphor. People often value images over text, as the speed with which the mind processes the information visually is faster.

Research demonstrates that metaphors have been strongly associated with innovation, with improved recall, and with key social abilities such as leadership. This use of compelling metaphors is also an important dimension of what is normally called creativity.

"Visual Metaphors ...have an important and increasingly indispensable, cognitive function.• ~~ s2

The role of metaphors provides a crucial link between metaphor, creativity and the human faculty of the imagination. Such a view forms a basis of Coleridge's philosophy. Coleridge understood metaphor as the power enabling the imagination to be put into action.s3

Metaphors also facilitate ones capturing of ones phenomenological experience of the world in a unique way. They are a means of linking subjective and objective experience, conjoining them and resulting in a fresh `fusion of horizons' ~4. They have the ability to connect together objects, events and actions that appear to be factual disparate and unconnected. They also provide a way of mediating between concrete and abstract thoughts. In the most general sense metaphors promote self-reflexivity.

Metaphors and Paradox

One of the interesting things about metaphor is that it allows for productive use of paradox. s2 Nielsen, p 118. s3 Tilley, p 9. sa Ibid. 38

Metaphors provoke and are in essence, paradoxical. This is because they juxtapose things

that are not normally compared or combined. Advertising provides many illustrations of this.

Since paradoxical visual metaphors are often used there to considerable/ profitable effect.ss

Vision is a particularly important sensory system, which also is highly complicated in the

reasoning process. Being able to picture one thing "before the mind's eye" and then to

mentally compare it with some other situation or object is by far the most common kind of

metaphoric thought.. Visual imagery is of equal and related importance in problem solving.

Yet another input says that children especially, are attracted to visual stimuli from just days

after birth.s6

However, there are a few disadvantages to the use of metaphors. Sometime, metaphors

employed may very well be difficult to decode or understand by those who do not share the

same frame of reference. In this manner, metaphors maybe utilized as vehicles of power in

the sense of social domains and contro1.57

Studies on the use of Metaphors

Studies show that metaphors are sometimes overused in websites, as a result of which the element if tension existing in the metaphor diminishes. According to Jacob

Neilson in his book "Designing Web Usability," web designer use metaphors to be overly clever and push the site in the direction that seems fun and appropriate within the metaphors.

55 Sherson, Grant "The Relevance of Semiotics to the Internet: How Web Designers use Meta Phors in Web Development'' http://vvww.ucol.ac.nz/~g.sherson/papers/semiotics.htm 1999 s6 (Accessed July 2000) Lawler, M John, "Metaphors we compute by", 1999. http://www- personal.umich.edu/~jlawler/meta4compute.html Ib~d 39

He also says that this leaves the user's real goal behind— effective navigation and acquisition of material. He remarks that users live in a real world and not in a metaphoric world. At the same time he also agrees that the use of metaphors can prove to be beneficial for two reasons.

First it creates a unifying framework within the site and second, metaphors can prove to be a learning experience, which allows the user to draw upon the knowledge they already have about the reference systems. An excellent example of a user interface metaphor in an ecommerce website is the "shopping cart" metaphor, which immediately makes the user understand its basic functionality. It also works like a real shopping cart where things can be place and removed according to the customer or shoppers convenience, as long as it is not paid for. Once the things are decided on, they can be taken to the checkout line.sg

Yet another study on metaphors in computers by Alan Cooper proves that metaphors are not a good idea to use. In his article, "The Myth of Metaphor" Cooper gives an example of software designers who often speak of finding the right metaphor, upon which they can base, their interface design. According to him, they imagine that rendering their user interface; in images of familiar objects from real world will provide a pipeline to automatic learning by their users. So they render their user interface as an office filled with desks, file cabinets, telephones and address books or a pad of papers, in the hope of creating a program with breakthrough ease of learning. He also says that by searching for that magic metaphor, one designer will be making one of the biggest mistakes in the interface design. He concludes his article remarking, "The idea that good user interface design is based on metaphors is one of

58 Nielsen, p 118. 40

the most insidious of the many myths that permeate the software corr~munity."59 This

research I will also analyze this so called myth on metaphors and its applicability in web

design. The newer third generation websites use navigational methods that are abased on

metaphors.

There are other metaphors and they can be categorized. This research aims at categorizing

user interface metaphors in B2C ecommerce web sites.

Web Metaphors vs. Desktop Metaphors

Web metaphors are based on a flat navigation system, where the where the document

targeted is presented in a single frame. The navigational system in the web is easy to grasp

for the end users to grasp and the productivity is almost immediate. Desktop metaphors in

contrast are based around a hierarchy, which is usually rooted in a , and the

navigation is based on the /hierarchy metaphor, which is better for experienced users.

This system allows the end user more flexibility.60

Information Architecture

Information Architecture (IA) in general is seen as a process of structuring and organizing a

website's content in the comprehensive category which is supported by a logically founded

intuitive navigation system.61 Metaphors play a vital role in information architecture

Analyzing and testing all metaphor options can be crucial element creating a functional s9 Cooper, Alan, "The Myth Of Metaphor" 6o http://v~~vvw.cooper.com/articles/vbpj_myth of _metaphor.html. Kindle, "Bootstrapping the Web With Existing Technology", June 24 1996 (Accessed, Octl 7, 2001) http://www.w3.org/OOP/9606_Workshop/submissions/61.2.html 41 interactive program with a high level of usability. In IA the usage of metaphors is a way to show and convey the inner site content though external (visible) components like graphic elements, layouts and menu placements.

Information architecture is related to ecommerce directly. IA is the science of logically processing the goal of the site and then constructing a blueprint before the designer dives in and puts things together. This logical process of determining the various decisions contributing in making a good website with effective navigation, appealing to the right set of audience and arranging the information according to the requirements of the user is an important part of ecommerce website design. For example, getting the navigation right the first time is the best way to achieve the comfort level for the user and this is highly possible if the strategies of information architecture are applied to the ecommerce websites.

Researchers and designers agree that a good architectural foundation for a website while designing helps prevent mistakes from cropping up later once the website design and execution is completed. A study shows that spending about 60 percent of the time in design, and then 40 percent or even less in building the site benefits. This also means more time spent up front means less time fixing problems later once site is executed. Information architecture uses metaphors for effective user interface.62

The metaphors in Information architecture are divided in to three broad classifications-

Organizational metaphors, Functional metaphors and Visual metaphors. Organizational

61 Information architecture-shaped knowledge into form, http://www.infoarch.ai.mit.edu (Accessed Jan 2001) 42 metaphors are used when the structure of the site is based on a group, system or organization.

Functional metaphors are related to the tasks that can be performed on the site and visual metaphors are based on the visual elements and graphics that are most familiar to most people in that particular cultural, group, or country.63

Information architecture, like the web is directly related to multimedia too. Based on the metaphoric classification in information architecture and multimedia, metaphors in B2C ecommerce website are classified. This classification is then further sub classified which would be seen in the analysis chapter of this research

Summary

A thorough search of the literature was conducted to present the various important concepts related to this study and its contribution to ecommerce websites. The three main concepts of ecommerce, user interface and metaphors were discussed in detail. The next chapter would discuss how based on the classification of metaphors in information architecture and multimedia, the metaphors in B2C ecommerce is classified. Examples of metaphors from the top 20 websites are used to support the classifications.

CHAPTER 4

ANALYSIS

The purpose of this Chapter is to analyze the top 20 B2C ecommerce websites and answer

the research questions proposed earlier. Chapter two presented the methodology which will

be followed in detail in Chapter 4 and 5. This Chapter begins with an introduction on how the

metaphor on the website looks and feels and therein classifies the.

Looking for something in the website and looking for them in the real world have

similarities. When a user explores the website, he/she has the feeling of exploring the real

physical place in some way or the other. This is because users have a model; a mental model

they work with, on a daily basis. This mental model helps the user to analytically think,

analyze, and associate, what they already know with what they come across in the form of

interface and therein work with the given interface effectively. With the use of the existing

mental models and previous experiences the user begins to develop his/her mental map.

However, if the user's mental model differs from the model of the website, errors will occur

and the user will get confused and therein frustrated with the website. Henceforth, while

designing a website model, the closer the design matches with familiar situations, the easier

the system will be to interface with. Based on these models, designers have categorized the

metaphors found and used in multimedia.

However, it is to be understood that there is no one right set of metaphors for an interactive system. Each highlights some elements of the metaphor while hiding others. This is because each element has different interpretation of the word that is represented. In addition, the 44 conduit metaphors suggests, that to have an effective, effortless and successful communication, the designer has to find one right visual and word.l Aiso it is important to note that though the visual convey the meaning to be conveyed, to avoid any kind of confusion for the user, the word acts like an anchoring element. In ecommerce websites, metaphors are important communication tools that relate objects in cyberspace to objects that are familiar in the physical world such as desktops, file-folders, and trashcans. Using a metaphor correctly helps the users navigate by providing a sense of place, setting expectations about what is possible, and how to go about getting things done. Therefore an appropriate metaphor should help viewers understand what to do, how it would be appropriate to the content and whether it is able to meet the expectations of the audience.

However one single common aspect in all metaphors is the source and the target. when a source is clicked on or information typed in, as in the case of search engines, target is achieved. Some times the source and target can also mean primary and secondary elements in the metaphor. A reaction between the two would create as tension, which makes user interface interesting.

Classification of Metaphors

The classifications of metaphors in this paper are primarily based on the classification of metaphors found in information architecture and multimedia. Accordingly, metaphors are classified into three major classifications- organizational metaphors, functional metaphors and visual metaphors.2 Based on this, an attempt is made to break down ecommerce B2C

Figure 4.1. User interface metaphor classifications

website metaphors. However, the second classification has been replaced and called navigational metaphors. This new name introduced, is seen in user interface design used in video games and computer desktops and multimedia. Another reason why this classification of metaphors is added in the ecommerce metaphor classification is because web and in particular ecommerce is about effective navigation. On working with theses categories, trying to analyze them, it was concluded that ecommerce is not only commerce online but the transaction can be only successfully completed if the navigations were easy and appropriate.

Therefore the function of the various metaphors in ecommerce is only navigation. Sub categories under these three main categories have also been created for the ease of understanding of the metaphor system. These are explained in the form of a chart shown below in Figure 4.1. 46

Organizational Metaphors

Organizational metaphors use the common forms of organizations to structure the site. These structures of organization play an intangible yet very important role in the design of ecommerce websites. The minor elements are grouped to form, one element of information/ structure which are allowed to act as individual elements. Also these elements relate to the existing mental model of the users, like a set of folders stacked in a file cabinet for box.

Though users interact with organizational structure everyday, they rarely think about these features/ elements. Therefore there is a semantic motion from the metaphorical element

(primary element) seen in the website to the real thing (secondary element) existing in the day-to-day activities of the user. To heighten its simplicity and usability, visual elements in combination of rhetorical are used in the creation of organizational metaphors. However it is important that these organizing metaphors align with the requirements of the customer forming one set. Organizational metaphors include structural metaphors. The structures of information define the primary ways in which users can navigate. A slick and simple design with a high level of understanding for the users is the advantage of using organizational metaphors. A detailed account of each category is furnished below with appropriate examples.

Structural Metaphors

Structural metaphors are the backbone to a website, which acts as an important part of the navigation, and also as a very strong visual element that directs the user's eye to the navigation system, making the website user friendly. This kind of metaphor is seen in almost all ecommerce websites. Structural metaphors commonly occupy the top and left side of the 47 website. Here, the iconic metaphors that help in accessing the information are grouped in one area to form one structure for easy accessibility. These are called structural metaphors primarily because the whole site receives a structural framework. This framework gives users a sense of navigation and location on the page, which significantly increases the navigation within the site and usability, does not suffer as a result. The structure encompassing metaphorical qualities is called structural metaphors as seen in Figures 4.2, 4.3 and 4.4. For example, these structures show similarity to the print design for instance the newspaper. In the first page of the newspaper, the left section contains a column that lists important headlines or contents with .the page number mentioned below for easy access. Also the name of the newspaper, important headlines and other important details are on the upper half of the page. Therefore, the top and the left side is the most important because it is the natural tendency of the user to read from top left to bottom right3. This pattern is taken from real world and used on the World Wide Web. A repeated use of one or two pattern/structures of navigation on the web, developed from print design, is seen, making users familiar to structures seen in the web today. Example of the two basic kinds of structure can be seen in amazon.com following structure number one and priceline.com following structure Number two. Therefore, this is evident of its metaphorical character with a diaphonic (combination two ideas- print page and web page) nature of the metaphor.

Since there are only two common kinds of structures seen in B2C ecommerce websites, the users are familiar with the framework and the system that backs it, that interface becomes

This grouping is done in different ways. Details of this will be discussed later in the research. However, this area concentrates on the primary and secondary navigation of the website. Also these metaphors group the information in the site into small categories for ease of access.

The website structures information to make it meaningful to the user. Structural metaphors can be divided in three categories: sequences, trees and networks. The first category could be either linear structures or sequences which show a meaningful ordering of single information units; like an, ordinary table of contents provides such a sequence. This is evident in the structuring of the content in ebay.com as in Figure 4.6. A tree or branching structure is often represented in hierarchical menu form. For beginners a small menu width and a high menu depth are preferred, whereas for experienced users, a high menu width and a low menu depth is preferred as seen in the upper part or primary navigation of amazon.com. Finally, a network structure is very general and flexible structure of items and links between these: it allows the access of arbitrary information from nearly any other point in the system4.

Ecommerce websites follow all the three categories of structural metaphors, depending on their users and the products and services they provide. In most cases, they are represented as a set of folders stacked on a long rectangular base, with the tabs showing the name of the

Figure 4.6. Structural metaphor category two- www.ebay.com Sl stack is narrowed and at the same time further divided for another set of navigation,. which is subsidiary to the folders above. When clicked on folder, the navigation is directed to a list on the left of the website, which in this paper has been called secondary navigation. The secondary navigation is a detailed version of what a particular folder in the primary navigation indicates. Amazon.com was one of the first website to create the tab metaphor structurally arranging the various categories in a slick format.5

Steve Krug in his book "Don't make me think" lists four reasons why people love the tab metaphor-

■ Tabs are self-evident- People are familiar with the tab concept, whether they

may not be familiar to the usage of computers or not.

■ They are hard to miss- People usually miss buttons and bars but the tab

concept is very difficult to miss, because they are visually distinctive, and

cannot be mistaken for anything but navigation.

■ They are slick- Web designers have always struggled in creating a effective

yet simple navigation metaphor. The tab metaphor is a result of this. If done

correctly, it does not involve elaborate graphics, thus reducing the time to

load; at the same time it is a very polished version of navigation, which is also

extremely effective and successful in ecommerce websites.

■ Tabs also suggest whimsical space- Tabs create an illusion of a physical

space, an illusion of an active tab, which when clicked on moves to the front.

SKrug, Steve. Don' t Make Me Think! A Common Sense Approach To We Usability. pg 78. 52

This is a simple trick but very attractive and effective.6

However, in examining the top ten B2C ecommerce websites, it is evident that eight out of the ten web sites follow the structure shown in Figures 4.2, 4.3, 4.4. This could be called as the first type of structural metaphors seen in B2C ecorrimerce websites. These include amazon.com, bn.com, half.com, ubid.com, netflix.com, hsn.com, buy.com, cdnow.com.

Ebay.com and priceline.com follow another structure as seen in Figure 4.5. Though it is different from the other ecommerce websites mentioned above, the structure is absolutely suitable for the business conducted online. Therefore it can be concluded that there are two major classifications of structural metaphors seen in e-commerce websites.

In the second type of structural metaphor, the number of categories the website caters to is less, in comparison to the structural metaphor seen in the example of Amazon.com. Also it is seen that, there are inputs (typed information) required, to move further in the navigation of the site. However it is evident that the website does have a top navigation structure. What differs is the side navigation structure and acts almost like e search engine. The left side navigation system in the structure is not available in the site instead a box form is seen on the right side of the website. This box form serves the requirement in the site. This structure is seen in example Figure 4.6.

Navigational Metaphors

Unlike navigating on the sea, navigation on a website is not a life and death issue.

6Krug, Steve, Don't make me think! A common sense approach to web usability. p 80-81 53

However, getting lost in a large website can be very confusing and also frustrating.

Navigation is no fun, unless right navigation is put under the user's feet. The result of this is getting lost. Navigational metaphors are those where metaphors are used to aid navigation within the site, making the navigation for the users easy and effective. A navigational metaphor aims in providing a familiar context that would make the search for information on the website less abstract. Icons and symbols indicate what is there in the particular page, and where to go from that page which can help navigation. This helps the user to navigate -where to begin and what are the options. If followed correctly the user should not have any problem navigating through the site. Softwares work on the background and icons and iconic metaphors control them. Examples are hyperlinks and icons like "continue" "Add to the shopping cart", "buy", "login" etc, which are powered by a program that runs behind the metaphor. Navigational metaphors are run based on two technologies, the push and the pull technologies. These two technologies function in ecommerce websites. These are discussed in detail in the previous chapters. Navigational metaphors are broadly classified in two categories as seen in the B2C ecommerce website. They are Location as metaphors, Iconic metaphors and hyperlinks. These three categories are discussed in detail below.

An example of navigational metaphors is the folder/ tab shaped site search engine is seen in several examples like amazon.com, priceline.com and most B2C ecommerce websites listed in the top 20 websites. It signifies that within the folder, terminologies can be searched.

Therefore, the character of navigational metaphors is epiphoric in nature as they transfer the

"Rosen Louis, Morville, Peter, "Information Architecture, for the worldwide web" p 49. 54 meaning from the primary element of search engine for example to the secondary element, which are a list of results. Therefore a semantic motion is evident making it metaphoric.

Location as Metaphor

Generally speaking, one of the key elements that determine the success of the website is its navigation scheme. There are certain navigation schemes that the ecommerce websites follow for the ease of the users to navigate effectively. The left side of the page and the top of the page is the chief navigation of these websites. The reasons, the reading of the english language is from left to right and from top to bottom. So, the eye automatically moves from left to right and from top to bottom. This is similar to the mental model- real situation of previous experience, spoken in the beginning of this chapter. This is kept as the base to derive such a navigation system. Therefore the user's eye automatically reads the top left of the page and then the top of the page. In this region of the web page, is placed important information that can lead users to their required destination. In comparison to the Left side of the web page, the upper part is more important and hierarchically comes first. The left side of the navigation is usually the subsidiary classification of the upper divisions of the site. The center part is the detailed account of the left side navigation.

The usage of a system, which marks the primary, secondary and thirtiary navigation in a website, is what gives it a metaphorical character. The user understands that the top navigation is the primary one and the secondary ane gives hirri/her the details of the primary navigation and the central navigation is a further detail of the secondary one. Due to the repeated usage of this system in websites, the short thinking that works in the mind of the SS

user does no longer exist when the navigation structure is seen, but instead taken for granted and navigation takes place. This implied meaning, which in metaphorical language is known as the vehicle (secondary element), interacts with the primary element, the navigation, is what makes it metaphorical. Due to this metaphorical nature of the navigational elements and its position on the website, the users visit the site and without further tension, navigate within the site. The gap between the tenor and the vehicle, which is the tension of the metaphor, is no longer prevalent or at times the tension level is very feeble depending on the user.

Therefore these navigational metaphors can be called overused metaphors.

Iconic Metaphors

Icons are small pictures that represent a file or an action or a program. Iconic metaphors are one step ahead. These icons encapsulate the qualities of a metaphor within them. This means they have a primary element that they represent and a secondary element that they draw parallel to creating a tension between the tenor and the vehicle. Icons are used anywhere were a word label is used; to activate menus and to perform actions. Iconic metaphors are used in e-commerce websites for similar purposes.$ In short iconic metaphors are those which represent a, particular activity on the website, at the same time consist of an implied analogy in which one thing is compared to another dissimilar thing. Iconic .metaphors are used for the following purposes:

• "To help the consumers work smarter"9 g http://www.acm.org/sigs/sigchi/chi96/proceedingsltutoriaUHorton~W11_txt.htm "designing icons and visual symbols" 9 Krug, Steve. Don' t Make Me Think! A Common Sense Approach To We Usability.p 78. 56

Icons like the ones above attract the user, making the user inquisitive about the iconic metaphor and the text that is associated with it. Also in most cases such iconic metaphors are associated with deals and offers that are beneficial tote customer. Example, Figure 4.7.

• "To represent visual and special concepts"

The lock is a metaphor for security. When clicked on the lock the information about the security of using the sight is retrieved issue like security is very important to the online users while using different modes of payment (Figure 4.8).

• "To save space"10

The shopping cart icon and the icon of the aircraft, help the users choose instantly the activity

For example the art is automatically associated with the buying process and when place next to the product on the web page, it helps the user to buy if required immediately. Similarly the aircraft icon helps the user to enter a program where the user has to key in the starting point and destination point to buy tickets (Figure 4.9)

• "To speed search"ll

The search engine like the one shown above is elaborate tool, which can narrow down the users search and retrieve what the user requires. It is a space saver to the web page designer and also a time saver to the user.

• "For immediate recognition"12

The concept of the mail associated to the email is already discussed under iconic metaphors.

Similarly the web page this icon is taken from is attempting to introduce the concept of a regular mail icon associate with the newsletter. The rhetoric here help anchoring the visual to what it what to convey the user (Figure 4.10).

" ibid 58

• "For better recall"13

These icons help the users recognize the activity associated with them, so much that they have become dead metaphors. The `go' visually transfers the user from one page to another when clicked on (Figure 4.11).

These metaphors shown in figure 4.7- figure 4.13 are only seen in the priceline.com and

1800flowers.com websites, making the websites different from the others and giving the user

a different experience which other websites do not give. Also the interface capability of these

metaphors is good and users can understand them immediately. To be cautiously clear, the

metaphors are labeled with text. The use of iconic metaphors help online customers get

started more quickly and master advanced features sooner. Also this system enables the site

to display a distinct style according to their requirement.16 Added to these advantages, icons

communicate by representation and initiate a process modern e-commerce websites have a

large number of functions requiring icons and suitable space saving strategies such as icon

grouping maybe necessary. Good iconic metaphors are communicative and therefore .easy to learn. However the dynamic labels which appear when the mouse is passed over icons, may aid the user. However, the use of iconic metaphors have become the default standard in ecommerce website today. Conveying more information in the design of the icons can make i

16 ibid 61 conic interfaces even more efficient."

H~perlinks

Hyperlinks have a click able nature to them. They are also metaphorical because users of a site automatically try to click on any underlined text, thinking that it is a hyperlink as shown in Figure 4.16. Hyperlinks, which visually stimulate the users and indicates pathl navigation, is also a navigational metaphor. These hyperlinks are as a standard blue colored text underlines. When the mouse rolls over this kind of text, the arrow of the mouse changes shape in to a pointed fingered hand and when clicked, the user is transferred from one page to another.

The colors of these hyperlinks also have a metaphorical quality to them. Most B2C ecommerce website display links: Links to pages that the user has not been before typically displayed in blue, whereas Links to the pages that the user has visited previously are displayed in purple or red. These help activating a better user interfaces. The differentiations in the color of the visited and unvisited links clearly show the user which part of the website is explored and which part is yet to be explored. The color blue as an unvisited link is now so much familiar among the users that the users no longer have to think about this aspect. This also brings in a global user interface, seen in World Wide Web.

" http://www.intellectbooks.com/iconic/dynamic/dynamic.htm "Dynamicons as dynamic graphic interfaces: interpreting the meaning of a visual representation" 62

Hyperlinks are also navigational metaphor. The user's eye scans the text, which is underlined

to see further details about a particular section. Since the hyperlinks indicate navigation from

one page to another, these can be grouped under navigational metaphors also. However the

primary element which is the underlined text (tenor), relates to the secondary element

(vehicle), giving a contextual idea of navigation from one place to another in the web. This

suggested movement by the underlined text is what makes the hyperlink metaphorical.

The iconic metaphors listed in Figures 4.14 and 4.16, are click able and aim at running a

program or getting information on a particular subject. The shopping cart icon in each page

takes the user through astep-by -step process to check out the items chosen by the user for

purchase. The email icon when clicked also runs a simple program on the background,

enabling the user access emails. In this case the icon is in the form of the mail/letter. This is a

very good example of iconic metaphor as it symbolizes the regular mail. when this symbol is

introduced in websites, the user recognizes it as an icon for e-mail automatically understands

the meaning. This way the user associates to an object in the real world to the ones in the

Internet and an interface is created as a result of this understanding.

It would also be evident that structural metaphors are basically a grouping of iconic

metaphors to form one unit.

visual Metaphors

Visual metaphors indicate the graphic elements that are well established and recognized by the user for its metaphorical qualities. They are based on those graphic elements that are 63 considered familiar for the specific topic/event/ feeling covered by the whole site or its section to create amood/ atmosphere of a season/event. One such classification of visual metaphor is the symbolic metaphor, which would be discussed in detail in this paper. Visual metaphor also relate to the feelings/thoughts running the mind of a visiting customer or user, to a particular site. The examples below display such form of metaphors. They add visual interest to the site and convey meaning to the user. The common visual metaphors seen are indications of the change of seasons, festival/holiday season etc, or a mood to be conveyed by the online store to the user, like sale, new arrivals etc for a particular season or event. The pine needles and the snowflakes on them relate to a cold winter day. When this visual element is related to a bookstore and books in specific, the thought that may role in the minds of customers is a cozy chair on a winter day, by the side of the window or close to a fireplace, reading a book leisurely. The feeling is what a metaphor can evoke, due to the primary and secondary elements, associated with a visual. Therefore the primary element is

Figure 4.17. Example of visual metaphors

the snow covered leaves forming the background for the name of the book store as in Figure

4.18 which symbolizes the book store and the book themselves and the secondary element is the feelings associated with the visual element projected in the website. Thus the primary 64 element helps the user construct a parallel implication. This is the tension between the primary element, which is the tenor, and the secondary element, which is the vehicle, in the metaphor. This secondary element according to Max Black's theory discussed in the literature review is not an individual thing but an entire system. However, the feeling associated with the visual element is not completely exhausted. Every prospective customer coming to the site, his/her own potential meaning associated with the visual metaphor present in the site.

Symbolic Metaphors

According to a definition, "A symbol signifies or stands for something else. Usually that something is concrete. It is not common for a thought or feeling to develop in to a symbol as symbols are universal and represent cultures, traditions and religions of family of origin.. .

Symbols direct and organize record and communicate large amounts of information in a quick way. Cultures rely on them to maintain order, discipline and moral ethics"1 g. Symbolic metaphors are the qualities of metaphor added to the characteristics of a symbol. These visuals do not directly say what they represent but remind us of something connected to the symbol. There is transference of elements in the form of semantic motion from the primary element represented in the website, to the secondary element which is something related to, existing in the real world. Also the first idea is transformed or j uxtaposed by the second to give the user a better a little excitement and challenge, which is called the tension in the metaphor. This is why they are called symbolic metaphors. This set of metaphors is placed under the main category of organizational metaphors because they help in categorizing the 65 information displayed in the web page. As seen in the examples below, products/services are grouped under each symbolic metaphor.

Metaphors like the ones shown in Figure 4.18, is symbolic metaphors. Such metaphors are frequently seen in ecommerce websites. These metaphors are used to symbolically categorize the various parts/division of the ecommerce website like Figure 4.19. They symbolize a category of products the particular page focuses on whereas the other examples, for instance the bell in Figure 4.19, symbolize a festival time like Christmas or a special product sale for a particular season. These metaphors are not click able and therefore they differ from the functional metaphors. They don't have a program running at the rear end.

Also it helps looking at visual metaphors from a broader perspective. For example the look of the B2C ecommerce websites are formal due to the rigid linear structures that envelop the page. At the same time a touch of casualness is prevalent due to the symbols and few other graphic in the page. Also the eye wanders scanning the page by its underlined text and brightly colored tab metaphors. The top navigation is the first visual metaphor a user would look at followed by the left side navigation and then the central area hyperlinks and icons.

The right side is also equally strong is some instances as the left side as this area consists of iconic metaphors that draw the eye towards it.

The white background is almost all the websites contrasts with the bright vivid color of the elements in the WebPages. The blue of the hyperlinks help the user scan the information

'g Marcus Arron, Metaphor Design in User Interface, May 1998, Vol 22, no.2 66 quickly. The visuals of the products displayed, in the central area, pulls the user's eye forcing the user to look at the displayed visual. At times the colors used in a particular page denoting a particular category of products or service offered are also metaphorical. For example a page in an online store, selling outdoors and garden products has green symbolically representing in its page. At the same time green is also a color that metaphorically brings in various feelings associated by every single user. These feelings absolutely depend on the user's imagination and mental model. Added to this, the casualness of the graphic elements like the symbols and icons further enhance the mood, making the whole experience a pleasant and cool one. The color blue is extensively used, symbolizing trust- a trust on the online store selling the products and services. Small color dots with percentage of discount mentioned is also a visual metaphor, which the eye recognizes as a favorable offer, on which the mouse is clicked on it. Amazon.com is one example that has elaborate display of visual metaphors.

Not all sites have such elaborate display of visual metaphors. Therefore every online store displays a character/ image to it users, which the eye sees and according to the user, helshe creates a image drawing parallel from what they have seen on the website to an imagination or a metal model that is existing. This image or secondary element absolutely depends on the user's mental model. It is necessary that the user has a good impression about the website, the first time it is visited, for the user to further scan through the information and navigate in the site.

Therefore, on a broader sense, every single element that contributes to creating an impression or a feeling or a parallel to what is exiting in the mind of the user is a visual metaphor. 67

Personalization

B2C ecommerce aims at efficient and speedy delivery of products and services to its end customers. Through this process of personalization, the e-retailer can interact with customers on an individual basis and understand their needs and preferences better through such interactions. Therefore, personalization, for example, targeting of advertisements and coupons, can be achieved with more precision on the Internet than by direct marketing or through communication via other medias like radio or television19. To achieve a higher level of personalization, e-businesses are using personalization technologies. They're creating perfectly tailored Web experiences that provide only the information and products the customer wants.

Figure. 4.18. Example for personalization on amazon.com 68

A site filled with a number of products and services that the customer does not want farces users to wade through options and content areas that are irrelevant to them. Such a model is frustrating, and it wastes customers' valuable time- time that could be better spent perusing products or services they truly care about. Building a unique boutique site not only helps convert browsers into buyers but also increases average order size and turns occasional purchasers into regular customers.

"Jupiter Communications has done research that says the sites that are using personalization had a 39 percent increase in their bottom line," says Larsen, vice president of marketing and business development at Net Perceptions. " 20

American Airlines Inc. has personalized its Web site so that its business fliers view it as a business airline and its leisure fliers are convinced it's a vacation carrier. Several sites such as the Amamzon.com and netflix.com, hsn.com, bn.com and several online clothing retailers such as art.com, etc, create the same personalization for their users.

Also personalization is also seen through the welcome note presented when the user logs-in to the website. In the case of stores Amazon.com as separate page is dedicated to the customer when they return to the online store, with the details of all the items they had browsed in their previous visits, and placed in their wish lists. Also the store welcomes the customer byhis/her name. The same level of personalization is seen in Netflix.com

19 «IBM India Research Lab", http://www.research.ibm.com/irUprojects/ecom.html, (Accessed on May 2002) 20 http://www.mahoneyinteractive.com/800.htm (Accessed May, 2002) 69

This way the user or the customer may not search for the products all over again instead access the products directly in a very short time. Stores like eBay and half.com, personalize by showing the customers account "My account" and the shopping cart as "Your cart" in bn.com. Therefore a certain level of personalization is to be seen in all these sites.

Personalization not only takes place for the customers abut on the other end over used metaphors have brought about a interesting twist in representing the shopping cart of the various stores. In many cases it is not the same boring old simple cart. In a real clothing store like Gap or 1800-flowers.com the shopping bag has the model which is provided in he real stores for shopping. Thus, matching the metal model of the user in a web store. 71

CHAPTER 5

RESULTS, FINDINGS AND DISCUSSIONS

The purpose of this chapter is to present the results of the statistical analysis of the data collected from the selection of the top 20 B2C ecommerce websites and to answer the research questions addressed in the literature review. Chapter two presented a detailed account of the terminologies and concepts that were applied in this research. Based on the literature review, an attempt is made to evaluate and analyze the existing B2C ecommerce websites in the previous chapter. An analytical matrix and graphical representation is used to represent the results. Also the reliability of the results was tested by conduction the user test.

Analysis Matrix

The analysis matrix was based on the analysis of the top twenty websites listed in NextCard ecommerce index.' The Nextcard ecommerce index is a listing of the top websites. The analysis (Table 1 and 2) and the graph (Figure 5.1) show that all top ten websites use organizational, navigational metaphors with the exception of visual metaphors, which is used only by few sites. The analysis also shows the various classifications of the organizational metaphors, navigational metaphors and visual metaphors that were used of these, structural and iconic metaphors are used frequently.

Studies corresponding also indicate that in the top 10 website, 100% use organizational metaphors, 100% use of navigational metaphors and 30% use of visual metaphors. Looking in detail further - a 100% use of navigational metaphors and 40% use the symbolic 72 metaphors. Similarly there is a 100% usage of functional metaphor in the form of iconic metaphors.

It is also noted that the percentage use of visual metaphors increases during festival seasons and special occasions, which creates a mood for festival as in the real physical stores.

Therefore, an illusion of the physical store is created online. This study is represented graphically, in Figure 5.1.

An attempt is also made to analyze the reliability of the classification of user interface metaphors created in this paper, through user testing and the result is that 90% of the users agree on the classification of the user interface metaphors in this study. 74

Comparative Study

This study also empirically investigated the top 10 websites to the bottom 10 websites listed

in the Nextcard.com listing. As a result it is seen that 90% of the websites analyzed have

organizational metaphors in the form of structures that give a strong framework to the site. At

the same time it is to be noted that 100% of websites had structural metaphors in the top 10

websites seen earlier. This is similar to the structures of organization found in the top 10 sites

discussed earlier. 60% of the websites have iconic metaphors, in comparison to the 100%

seen on the top ten websites. Visual metaphors dropped to a 20%, Figure 5.2 and Figure 5.3.

The overall analysis of the last 10 websites can be concluded that though navigation was

simple and straight forward with a bunch of hyperlinks and icons, the sites were boring and

the process of navigation is not amemorable/attractive one anymore. With this comparative

analysis a one questions emerged- was the use of user interface metaphors one of the reasons

for the success of the top 10 websites?

The answer is yes as well as no. User interface metaphors do contribute to the success of an ecommerce website. As we recollect from Chapter 2, the design of the website is not everything to the success of the ecommerce website, though the design is the face value and does matter, as far as attracting the customer. Users do get fascinated to a well organized and designed page and site. But all that fascination is for few minutes. After a while it is all about navigating and finding the products and services they are searching for. It is business after this point they are interested in which is controlled by a highly efficient back end program and good architecture. The analysis also reveals that the lesser use of visual and other 75

Navigation becomes boring and monotonous, especially if the navigation is by as set of rhetorical and hyperlinks. The punch in the website disappears. Also with its important positive characteristics like recognize ability, the quick scanning of the eye, better recall, and space savings concepts also disappear from the site. With the lack of the tension created by the metaphor's primary and secondary element in the users mind, the illusion of a physical space and metal model also is lot to a great extent. If the back end program is fast and satisfactory and at the same time the journey is made pleasant and enjoyable due to the design through every page of the site, an unforgettable user experience will motivates the user to come back to the site again and again.

Table 3 Reliability user test results 77

User test was conducted to evaluate the reliability of the study classifying metaphors. As a result of this study 90% of the users agreed on the classification of metaphors in the B2C ecommerce website design. The study was conducted based on the method mentioned in

Chapter 2. Three users who had experience using the World Wide Web and shopping online were randomly picked and elaborated on the classification of metaphors. They were given a questionnaire to answer based on the study and explanation given to them. The results of the study are as above (Table 3). Questionnaire to the User testing could be found in Appendix A in this study.

To understand better the usage of all the above-classified metaphors, the number one websites are taken as examples for a detail study, recognizing and under standing them.

Evident from the Figures 5.4, 5.5, 5.6and 5.7, the structural metaphors occupy the top left part of the website. The search engine, which is an iconic metaphor, embeds within this structure. The symbolic metaphors are placed parallel to it forming the heading for the content of a particular page. Hyperlinks are the underlined texts that are found in almost all pages. ~g

overuse of User Interface Metaphors in B2C Ecommerce Design

Metaphors are temporary bridging concepts. When they become ubiquitous, they die. The process is similar as in linguistic metaphors. Also, successful metaphors end up as overused metaphors or as described by Jacob Neilson "dead metaphor". The familiarity provided by the metaphor during earlier stages of the use gives way to familiarity with the interface due to the actual experience. Thus, after a certain level of usage of the metaphors, it is the actual details of appearance and behavior, i.e. the physics that form much of the substantive knowledge of an experienced user than any over anchoring metaphor. However, the power of metaphor comes early in usage and is rapidly superceded by the power of actual experiences.

It is a characteristic of the metaphor, no matter how deeply a figure may penetrate a language; it never loses its figurative potential. when the metaphor is overused metaphors or dead, the concept is a convention and not metaphor anymore

New Metaphors

While designing the B2C ecommerce website interfaces, one is limited to the metaphorical resources at hand. The reason is that the metaphorical resources should be familiar to the users in order to work with them. On the other hand an unfamiliar interface metaphor is no longer a metaphor at all. It is to be accepted that one cannot design metaphors the way one sees aself-consistent, self-description of appearance and behavior. Therefore, there are very few alternatives for the metaphors that exist today in B2C ecommerce websites. However many online retailers use metaphors on their site to add personality and help build a brand identity. An example of this would be http://v~~avw.garden.com, which takes metaphors too far and confuses customers by calling its shopping cart "wheelbarrow." Online experienced 81 customers expect to see something called "shopping cart on the online retail store and new customers on the other hand not knowing what to expect and would get absolutely confused.

Therefore, a drastic change in the use of user interface metaphors (changing from the existing metaphors to new ones) can get online customers and users confused. It is a fact that users scan the web pages very fast for the information/ services they want. Therefore, making them spend sometime trying to understand the various elements and their corresponding functions would make the online customers leave the site. Thus, the online store loosing valuable

usiness.

An alternative that could be suggested as used now at a very low level is personalizing the site to acquire higher brand recognition. Minor changes to the websites' user interface metaphors can be made this way. An example of such a change is the shopping bag concept that is being used by several well-known brands like Gap. Here the metaphor comprises of the brand identity on the shopping bag. Example of such a store is http://www.gap.com.

Thus the characteristics of user interface metaphors such as easy recognition and memorability of fundamental concepts conveyed through visuals/signs or images that match with the existing metal models.

Are the Existing User Interface Metaphors in B2C Ecommerce

Websites Appropriate?

All metaphors in the B2C ecommerce websites are not appropriate- though they remind of an existing mental model (the mental model of shopping in reality) they do not satisfy the 82 exceptions of the online user /customer completely. This is evident among new users as they do struggle to figure out how the shopping cart metaphors actually work. The reason, the shopping cart does not at all-time show what is there is the cart or all the items the customers has picked. To see what is there in the cart, the customer has to go to another window, which lists the items in the shopping cart. To continue shopping after taking a brief look at the shopping cart the user has to return by a different route. In some cases the user interface button, would lead to the store entrance and if at all a short cut is attempted, then the shopping cart would mysteriously empty. Therefore working out the appropriate user interface for the metaphors that exist in the ecorrunerce websites is very important.

Summary

The top 20 websites listed were analyzed and the data thus collected using the matrix goes to prove that websites use a particular patter to achieve maximum usability. Metaphors are tools that aid better navigation and create an interesting effect during this navigation. Also the usage of metaphors in the top twenty websites show that as a standard, ecommerce websites use organizational and navigational metaphors in all most all their pages. Symbolic metaphors axe like the icing on a cake which forms a decorative element. At the same time they also help navigation by categorizing a particular section for clear understanding.

Therefore their use is comparatively very low to the other classification of metaphors mentioned above. However, it is seen that the usage of symbolic metaphors increase substantially compared to the other classifications of metaphors, during special occasions, festivals and holiday seasons. 83

CHAPTER 6

CONCLUSION This study was undertaken to analyze and classify user interface metaphors in B2C ecommerce websites. Implicit from this study is that the use of user interface metaphors will improve the visual and working experience on an ecommerce website. The purpose of this chapter is to present the conclusion of the study and offer recommendations based on the findings of this study.

As a result it could be concluded that metaphors have been and will continue to be a significant component of user interface design in B2C ecommerce websites, at all levels and mental models. They simplify and help provide easy navigation within the site. As technology improves and develops, and functions on the website increase, the challenge of enabling more number of people to use the website, will pave way to new metaphorical interfaces that will closely match with the mental models of the users.

At the beginning of this study, the researcher brought forth research questions about the classification of user interface metaphors in B2C ecommerce website design and how this classification could be justif ed as an appropriate one. The classification of the metaphors in

B2C ecommerce websites is based on the classification of metaphors in information architecture and multimedia as seen in the literature review. This is because information architecture is directly related to web design and multimedia. 84

Many ecommerce websites have metaphors that are used over and over again, loosing the tension in the metaphors. Most overused metaphors are usually successful metaphors. Since the power or tension in the metaphor comes only in the earlier stages of the usage and is gradually superseded by the power of actual experience, the metaphor used is no longer a metaphor but is a convention. However, new metaphors can be replaced to existing overused metaphors, provided the interface is one of familiarity and matches with the existing metal model of the user.

The use of metaphors adds personality to the ecorrunerce site to build brand identity.

Ecommerce websites are personalizing their websites to improve band recognition, which is related to the shopping experience in the real world. This is an alternative that is suggested to replace old and overused metaphors.

Although the results from this study show increased use of metaphors in the top ten websites than the bottom ten, it is not proved that the contribution of metaphors is one of the factors to the success of the websites. The success of an ecommerce website rests on several design as well as business factors. A well designed websites with the use of right set of metaphors may not do as well to a site that has very little use of metaphors or rather no metaphors. At the same time a successful ecommerce website is dependent on considerations of the major users and not minor user's culture, age, education etc., of the target population. The finding of this research evidently indicates that metaphors increase the level of navigation, usability and credibility in the ecommerce site. In other words, the appropriate use of metaphors would increase usability and effective navigation among users creating a equally interesting 85 shopping/ browsing experience. Thus a designer must keep in mind that a successful metaphor is user-centered that incorporates a balance among the designer and user.

Limitations

This study was conducted based on a thorough review of the literature and the classifications of user interface metaphors found in the multimedia. Also the selections of the websites were based on the data provided by a review of the top 20 B2C ecommerce websites, published in v~~vvw.next card.com, in 2000. Since 2000, several new B2C ecommerce sites, which are employed in this study, have reached the top 20 status and several have declined the popularity. Thus the relevance of the data of B2C ecommerce websites should be considered based on the time line this study was conducted. However the basic classification of user interface metaphors is timeless regardless of the trends as the roots of this classification and study is from the classification of user interface metaphors in information architecture and

.multimedia. For these reasons the result of the study should be considered in this light. At the same time this study limits to American websites as the pattern of user interface would change for websites from other cultures and so would the metaphors.

This study is a pioneering one, in the sense that it is the first research on the classification

User Interface Metaphors on B2C ecommerce websites. The other limitation of the study is that the reliability of the study is measured through a user testing, but not the validity of the study. This is because the study aims at understanding the metaphors see on the B2C ecommerce websites, and therefore as part of this process classified them for easy understanding. This study aims to guide researchers and designers as how to design and use 86 effectively user interface metaphors for the websites. However the study is not tested to know if the study works in the real situations and towards what goals it works.

Future Study

The following recommendations for practice and further research are made based on the outcomes of this study.

• Since this study measured the reliability of the classification of user interface

metaphors in B2C ecommerce websites, as a next step the validity of the study could

be measured by randomly picking users to talk about the various metaphors they see

on the top ten sites.

• With the developments in technology, the requirements for new user interface

metaphors will be required. Therefore as study could be conducted as to how might

metaphors be designed for different kinds of intelligence.

• Ecommerce is going global and people can buy or sell goods and services from any

part of the world to people on any part of the world. In such cases it is necessary to

develop metaphors that can reach to people from different cultures. As a process in

creating such metaphors, a study could be undertaken on how metaphors be designed

for different cultures that different by such dimensions as age, gender, national and

regional groups or professions.

• Advanced user interfaces require consideration of new metaphors and repurposing of

the older ones. A study which formulates to assist researchers and web developers in

achieving more efficient effective ways to communicate to more diverse user

communities can be conducted. 87

• Since the websites analyzed in this study are from the top 20 list published in 2000, a

similar analysis could be conducted on the more recent listing of B2C websites seen

online. Also recommended is a similar compassion of the usage of user interface

metaphors in the top 10 websites o the bottom 10 websites in the new listing.

• Since people of all ages use the ecommerce website, the navigation pattern would

change according to the mental framework of the user. It would be an interesting

study to see how people navigate based on their age, culture, and gender. 88

APPENDIX A. USER TEST QUESTIONNAIRE

The purpose of this appendix is to verify the scoring criteria in the evaluation matrix. The

User test is based on the process of reliability measured in the methodology and supports the research questions. Thus the objectivity of the questions is important to gain correct information from the users. This small scale user test represents that each user has similar understanding from the sample websites. 89

ACKNOWLEDGEMENTS

It is a pleasure to thank the many people who made this thesis possible. It is difficult to overstate my gratitude to my Major Professor, Ms. Sungyun Ryoo Kang. With her enthusiasm, her inspiration, and her great efforts to explain things clearly and simply, she helped to make this research a success. I would like to express my sincere appreciation to Mr.

Roger Baer for his help support and guidance during the years of pursuing my Masters. Also, a special thanks to professor Scott Chadwick for his guidance and valued suggestions to this research.

I thank my husband Sudheer Matta, for his effortless support. His encouragement always lifted my spirit and enabled me to put forth the extra effort to complete the thesis.

I would also like to thank my parents and brother, for the years they spent to encourage me to work hard and follow my dreams.
