Engineering Accessible Web Applications
Universidad Nacional de La Plata Facultad de Informática Thesis submitted in fulfillment of the requirements for the degree of Doctor (Ph.D.) in Informatics Science Engineering Accessible Web Applications. An Aspect-Oriented Approach Author: Mg. Adriana E. Martín Supervisor: Ph.D. Alejandra Cechich Co-Supervisor: Ph.D. Gustavo Rossi September 2011 ABSTRACT Building Accessible Web applications is nowadays a must. Every day more and more users with different abilities and/or temporally or permanent disabilities are accessing the Web, and many of them have special difficulties in reaching the desired information. However, the development of this kind of Web software is complicated for several reasons. Though some of them are technological, the majority are related with the need to compose different and, many times, unrelated design concerns which may be functional as in the case of most of the specific application’s requirements, or non- functional such as Accessibility itself. Even though, today there is a huge number of tools and proposals to help developers assess Accessibility of Web applications, looking from the designer perspective, there is no such a similar situation. It seems that creating accessible Web sites is more expensive and complicated than creating Web sites and then assessing/modifying them. Although this feeling may be largely true, the benefits of modelling Accessibility at early design stages outweigh the needs of a developer to implement that Accessibility. In this thesis, we present a novel approach to conceive, design and develop Accessible Web applications in an Aspect-Oriented manner. In order to reach our goal, we provide some modeling techniques that we specifically developed for handling the non- functional, generic and crosscutting characteristics of Accessibility as a quality factor concern. -

Appendix a the Ten Commandments for Websites
Appendix A The Ten Commandments for Websites Welcome to the appendixes! At this stage in your learning, you should have all the basic skills you require to build a high-quality website with insightful consideration given to aspects such as accessibility, search engine optimization, usability, and all the other concepts that web designers and developers think about on a daily basis. Hopefully with all the different elements covered in this book, you now have a solid understanding as to what goes into building a website (much more than code!). The main thing you should take from this book is that you don’t need to be an expert at everything but ensuring that you take the time to notice what’s out there and deciding what will best help your site are among the most important elements of the process. As you leave this book and go on to updating your website over time and perhaps learning new skills, always remember to be brave, take risks (through trial and error), and never feel that things are getting too hard. If you choose to learn skills that were only briefly mentioned in this book, like scripting, or to get involved in using content management systems and web software, go at a pace that you feel comfortable with. With that in mind, let’s go over the 10 most important messages I would personally recommend. After that, I’ll give you some useful resources like important websites for people learning to create for the Internet and handy software. Advice is something many professional designers and developers give out in spades after learning some harsh lessons from what their own bitter experiences. -

Introduction What Is Javascript?
CS2361–Internet & Java 2.1 Introduction What is JavaScript? Discuss its features ¾ JavaScript is a client-side scripting language and is the defacto scripting language for most web-based application. ¾ It is used to enhance the functionality and appearance of Web pages by making it more dynamic, interactive and creating web pages on the fly. ¾ JavaScript is interpreted by the browser. ¾ Statements are terminated by a ; but is not required. ¾ JavaScript standard is defined by ECMA to which Netscape is fully compliant whereas IE complies with a modified version known as JScript. ¾ The <script> element introduces a client-side scripting language. ¾ It is generally placed within the <head> element, but can also be part of <body> o The type attribute specifies the MIME scripting language and its value is text/javascript for JavaScript. <html> <head> ... <script type="text/javascript"> <!-- Put your JavaScript code here // --> </script> </head> <body></body> </html> ¾ The script is executed either when page is loaded or when given event occurs. ¾ The script will not be executed if it is disabled in the browser environment. ¾ For browsers that do not understand javascript, the entire script code is enclosed within xhtml comment. ¾ Script can also be placed in a separate file and pointed by src attribute. ¾ JavaScript is an object-oriented language and has a set of pre-defined objects (document, window, form, etc) to access and manipulate XHTML elements. ¾ An object's attribute is used to set/read data, whereas a method provides service. ¾ Javascripthas -
AN EXPLORATION INTO TWO SOLUTIONS to PROPAGATING WEB ACCESSIBILITY for BLIND COMPUTER USERS by Stephanie Rose Hackett B.S., Univ

This project examines two distinct solutions, lawsuits (a consumer-driven solution) and AcceSS 2.1 transcoder (a technology-driven solution) to provide more information on two under- researched methods that could have far-reaching impacts on Web accessibility for the blind. First, an evaluation of the intraclass correlation (ICC) between homepage Web Accessibility Barrier (WAB) scores and WAB scores of levels 1-3 found that the homepage is not sufficient to detect the accessibility of the website. -
Extending Expression Web with Add-Ons
APPENDIX Extending Expression Web with Add-Ons Any good web editor must be extensible, because the Web is constantly changing. This capability is one of the strongest assets of Expression Web; it means that third parties can add new features that are easy to use inside of Expression Web. You don’t have to wait for Microsoft to release a new version to get more features. I am talking not about code snippets, like the one we created in Chapter 2, but about fea- tures that make it easy to add e-commerce capabilities using PayPal buttons or a shopping cart, improve your search engine ranking using Google Sitemaps, or add Flash banners and interactivity without becoming a programmer or a search engine specialist. Some of these add-ons are commercial applications that charge a fee, and others are created by someone who sees a need and creates a free add-on. At the time of this writing, there were over a dozen add-ons available for download and more actively under develop- ment. A current list is available at http://foundationsofexpressionweb.com/exercises/ appendix. Add-ons are usually easy to install and use. Once you have found an extension for Expression Web that offers you the ability to extend what you can do, download the add-on, and follow the extension maker’s instructions on how to install it. Most add-ons will have an installer that creates either a toolbar or an entry in one of the menus. Adding PayPal Buttons The first add-on I will show you creates a menu item. -

Nonvisual web access can be improved by applying and non-visual. For the most part, our design attention is focused the following guidelines for source code design. on making decisions that affect the visual, or surface, layer — Shneiderman defines universal usability as an approach to design colors and type, screen dimensions, fixed or flexible layouts. that is focused on “enabling all citizens to succeed in using However, much of the power of the technology lies beneath the information and communication technologies to support their surface, in the underlying code of the page. There, in the unseen tasks” [18]. A focus on page code design improves the universal depths of the page code, we make decisions that influence how usability of web pages by addressing access challenges in a well, or poorly, our pages are read and interpreted by software. In variety of contexts. For instance, the small viewport on mobile this paper, we shift our attention beneath the surface of the web devices presents many of the same challenges as nonvisual access. and focus on design decisions that affect nonvisual access to web This paper concludes with a discussion of how these guidelines pages. can be applied to improve web access for mobile users.
