Wayfinding in the Urban Environment January 2008 CAMPBELL and LYONS: Wayfinding in the Urban UTSG Southampton Environment WAYFINDING IN THE URBAN ENVIRONMENT Ms Mhairi Campbell Research Fellow University of the West of England Professor Glenn Lyons Director Centre for Transport and Society University of the West of England Abstract Having difficulty finding a destination can be costly to individuals and organisations. Individuals have to endure feelings of frustration, confusion and even fear, while time is wasted and appointments are missed. This paper examines, based upon a series of in-depth interviews, how well a selection of technology-mediated wayfinding services are meeting travellers’ requirements. Firstly a sample of PDF documents providing directions (found using Google) is compared in terms of information format and content to the requirements of individuals in assisting their comprehension of directions. The use of and attitudes towards a further five forms of technology- mediated wayfinding assistance are considered. What happens when travellers experience a problem finding an unfamiliar destination is explored, discovering distinct behaviours towards finding destinations: ‘always find it’; ‘persevere’; and ‘occasionally abandon’. Following this, occasions when the traveller abandons the unfamiliar journey are examined, with the emergence of three categories of wayfinding problems: complex layouts; simultaneous travelling and wayfinding; and comprehension of directions. Only by understanding these issues, together with the needs and desires of people wayfinding in the urban environment, will it be possible to ensure that current and future information provided for wayfinding is both useful, i.e. the information is what is needed by the traveller, and usable, i.e. the traveller is easily able to make use of the information. Introduction Having difficulty finding a destination can be costly to individuals and organisations. Individuals have to endure feelings of frustration, confusion and even fear (Lynch, 1990), while time is wasted and appointments are missed. Organisations can lose business or clients, as well as incurring the costs involved in staff time spent finding destinations themselves or directing others. The majority of research into wayfinding has used experimental techniques in relation to cognitive functions within the fields of psychology and geography. There remains a knowledge gap concerning the impact different forms of assistance can have on unfamiliar wayfinding and how the traveller copes with finding unfamiliar destinations. A growing number of forms of technology-based wayfinding assistance exist and analysis of their development (see later) is evolving. However, there is a paucity of research into how useful and used such assistance is in relation to people’s needs and experience of wayfinding in practice. This paper aims to make a contribution to better understanding the place of technology-mediated assistance in meeting people’s needs and concerns when undertaking unfamiliar journeys. It begins by focusing upon a relatively widely available and accessible form of assistance – bespoke directions to a given destination made available as an electronic document. Examination of the nature of assistance provided in a sample of such documents is considered alongside the preferences for wayfinding assistance expressed by individuals participating in in-depth interviews. Drawing upon this interview data, the paper goes on to consider attitudes towards a variety of other forms of technology-mediated assistance. Wayfinding problems, which motivate the need for provision of assistance and take-up of assistance to resolve them, are then considered in terms of a number of issues: occasions when people abandon unfamiliar journeys; concerns over wasted time; and categories of wayfinding problems. The next section of the paper offers a brief examination of the literature to set a context for addressing the elements above. This paper is produced and circulated privately and its inclusion in the conference does not constitute publication. 2A1.1 CAMPBELL and LYONS: Wayfinding in the Urban January 2008 Environment Southampton UTSG Background Human wayfinding research examines: “how people find their ways in the physical world, what they need to find it, how they communicate directional information, and how people’s verbal and visual abilities influence wayfinding.” (Raubal et al. 1997). Three types of wayfinding are defined by (Allen, 1999): ‘commute’, ‘explore’ and ‘quest’. ‘Commute’ involves following a familiar route from a known origin to known destination with low levels of uncertainty for the traveller. Generally there is little conscious effort required. The ‘explore’ form of wayfinding aims to discover new information about an unfamiliar environment. This involves a familiar start and destination, often the same place, with the aim of finding new places and new paths between these new places and places already known to the traveller. This wayfinding involves greater levels of uncertainty for the traveller, as to whether the information they gather from the exploration will be of any use. Unlike commute wayfinding which generally uses automatic memory and low levels of effort, explore wayfinding involves conscious cognitive processing. Finally ‘quest’ wayfinding involves uncertainty for the traveller. The traveller is proceeding to a specific destination which is unfamiliar to them and which they may not have previously visited. ‘Quest’ wayfinding requires high-level cognitive abilities, greater than those required for explore wayfinding (Allen, 1999). The focus upon unfamiliar travel within this current paper falls within quest wayfinding as defined by Allen (1999). A substantial amount of research has been conducted on wayfinding, especially within the fields of psychology and human geography. Much is known about the cognitive functions of how people tend to find their way (see Kitchin, 1994; Løvås, 1998; Timpf, 2002; and Tversky, 2003), and how this is a hierarchical process (see Hartley et al. 2003 and Maguire et al. 2003). When people are deciding which route to take, as pedestrians and when driving, several factors are taken into consideration: the shortest path; the path with the least changes in direction; and taking the longest part of the path first judged by line of sight, (Golledge, 1993; Dalton, 2003). These factors are generally of greater importance than the amount of time taken to travel the route. People generally attempt to minimise the length of time to create strategies for wayfinding routes (Golledge, 1993). However, much of this work has involved experimental conditions, with less research focussing on real-life practicalities of wayfinding, especially within complex urban environments. While people can often enjoy the fun and satisfaction of wayfinding (Passini, 1984), this would usually be in the context of leisure time. It is unlikely that many people would consider finding their way from a city centre to a hospital, or meeting with their bank manager, a leisure activity. Satisfaction will also depend upon the pressures associated with the wayfinding task such as timely arrival at a destination and how effectively, within such constraints, the individual is able to wayfind. A study by Devlin and Bernstein (1997) involving an on-screen wayfinding exercise found that lower reported frustration levels correlated with higher confidence. The level of frustration also correlated positively with the error score, suggesting a relationship between lower frustration and fewer errors. When people lose their way, they become angry, hostile and indignant (Abu- Ghazzeh, 1996). This is corroborated by the finding that when using public buildings, if visitors know where they are going, they experience less stress (Evans et al. 2002), and research which reported that wayfinding ease was found to positively enhance the experiences of museum visitors (Talbot et al. 1993). A further link between feelings of stress and problems wayfinding is given by (Malinowski and Gillespie, 2001) who found that the task of orienteering with a map and compass was predicted by anxiety, the greater the anxiety level, the lower the orienteering performance. They argue that if even 1% of the tourists visiting large cities get lost, that is potentially a huge number of confused anxious tourists (Malinowski and Gillespie, 2001). With the ongoing emergence of methods and services to assist travellers find their intended destinations, research is emerging concerning technologically-mediated assistance for wayfinding, such as that by Kray et al (2003) who discuss the different ways information can be provided on PDAs and suggest guidelines for deciding which format is best for a given situation. This research found that among experienced map users, when using mobile wayfinding devices, an aerial view (the view usually shown by traditional 2D maps) was generally preferred over the eye-level view. This notion of technologically-mediated assistance replicating traditional means of assistance is also touched upon by Zipf and Hunolstein (2003) who found that since most tourists are content with paper maps and tourist guides, any mobile forms of assistance aimed at tourists are required 2A1.2 January 2008 CAMPBELL and LYONS: Wayfinding in the Urban UTSG Southampton Environment to match the range of information provide by the existing paper medium to entice tourists to use mobile guides.

    Running Head: DIRECTION QUALITY AND WAYFINDING EFFICIENCY 1 How Good Are These Directions? Determining Direction Quality and Wayfinding Efficiency Amanda J. Padgitt and Alycia M. Hund Illinois State University DIRECTION QUALITY AND WAYFINDING EFFICIENCY 2 Abstract Our goal was to specify the effectiveness of wayfinding directions in a complex indoor environment. We measured direction quality using effectiveness ratings and behavioral indices. In Study 1, participants provided effectiveness ratings for seven combinations of wayfinding descriptions. In general, ratings were higher for route details than for survey details, and ratings increased as the number of features increased. Moreover, people with a good self-reported sense of direction gave higher ratings to survey descriptions (cardinal directions and distances) relative to those with a poor self-reported sense of direction. In Study 2, participants provided effectiveness ratings for route and survey directions before and after wayfinding using these directions. Route directions resulted in fewer wayfinding errors and higher effectiveness ratings than did survey directions. People with a poor self-reported sense of direction made more wayfinding errors and provided lower effectiveness ratings than did people with a good self- reported sense of direction. We also demonstrated important relations between wayfinding errors and ratings after wayfinding, as well as links with sense of direction, wayfinding strategies, and mental rotation. Keywords: wayfinding, survey perspective, route perspective, sense of direction, effectiveness ratings, mental rotation DIRECTION QUALITY AND WAYFINDING EFFICIENCY 3 How Good Are These Directions?

  • Cultural Differences in Providing Wayfinding Directions Bachelor Thesis
    UNIVERSITEIT TWENTE Cultural Differences in Providing Wayfinding Directions Bachelor thesis Katrin Bangel Student: Katrin Bangel s0157058 Tutors: Dr. M.L. Noordzij Enschede, 6/7/2009 Dr. R.H.J. van der Lubbe Cultural Differences in Wayfinding Directions 2 Abstract This study examined differences in direction giving within western society. Our first experiment was mainly intended to compare the frequency of use of several spatial terms of reference provided by Americans, earlier assessed by Hund et al. (2008), to direction giving behavior of the Dutch population. Presenting a fictive model town, we asked 30 Dutch participants to provide wayfinding descriptions to fictional addressees in route (driving through the town) and survey situations (using a map). First, our results yielded that native Dutch speakers less frequently use cardinal descriptors than American native speakers do. Therefore we propose that cardinal concepts are less present for Dutch people. Second, significant effects of referent perspective on the mention of several wayfinding descriptors were found. Further differences in language use were yielded for both recipients perspectives. Based on these facts we conclude that, although cardinal concepts seem to be less present for them, Dutch people are able to flexibly adapt to the needs of their addressees during direction giving. In a second experiment Dutch participants conducted an adjusted version of the wayfinding task developed by Hund et al. (2008). When cardinal directions were not indicated and explicitly mentioned during introduction of the model town participants did not mention cardinal cues at all. Introduction We often ask each other to provide spatial descriptions of the environment, for example to inform others about the location of objects, or the location of places, such as public buildings or railway stations.

  • Place-Based Wayfinding Andrew Rogers, Sarah Howard, and Kirsten Matsumoto
    Place-based Wayfinding Andrew Rogers, Sarah Howard, and Kirsten Matsumoto Summary The objective of this series of lessons is for students in any part of the world to ground their study of Climate Change and Stewardship of the Earth in their own sense of place. Through a personal and place-based lens, students develop empathy toward their home as they relate it to present day issues as well as to those of their ancestors. From one’s own community to the stars in the sky, students identify their place in the universe, and more concretely, learn the cardinal directions. The lesson plans, while based in science, span cultural, geological, and political answers to the question “Where are you?” Using astronomy, the path of the sun, hands as measuring tools, and Pacific Islander navigation traditions, students employ Next Generation Science Standards (NGSS) Science and Engineering Practices such as: developing and using models, constructing explanations, and using mathematics and computational thinking. Extensions include geocaching, map-reading, compass use, and navigation triangulation. These lessons can be adapted for students of all ages. tags: wayfinding, geocaching, navigation, stars, models Key Concepts - Align place-based science with environmental teaching - Unify personal stories and Environmental Pedagogy - Bridge communities, culture, and location to identify place - Find cardinal directions by day and by night Next Generation Science Standards: Science and Engineering Practices - Developing and using models, Constructing explanations, Using mathematics and computational thinking Crosscutting Concepts - Scale, proportion, and quantity, Systems and system models, Disciplinary Core Ideas - Earth and Space Science ESS1.

  • Techniques for Assessing and Improving Performance in Navigation and Wayfinding Using Mobile Augmented Reality
    TECHNIQUES FOR ASSESSING AND IMPROVING PERFORMANCE IN NAVIGATION AND WAYFINDING USING MOBILE AUGMENTED REALITY by BRIAN F. GOLDIEZ B.S.A.E. University of Kansas, 1973 M.S. University of Central Florida, 1979 A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Modeling and Simulation in the College of Arts and Sciences at the University of Central Florida Orlando, FL Fall Term 2004 © 2004 Brian F. Goldiez ii ABSTRACT Augmented reality is a field of technology in which the real world is overlaid with additional information from a computer generated display. Enhancements to augmented reality technology presently support limited mobility which is expected to increase in the future to provide much greater real world functionality. This work reports on a set of experiments that investigate performance in search and rescue navigating tasks using augmented reality. Augmentation consisted of a spatially and temporally registered map of a maze that was overlaid onto a real world maze. Participants were required to traverse the maze, answer spatially oriented questions in the maze, acquire a target object, and exit. Pre and post hoc questionnaires were administered. Time and accuracy data from one hundred twenty participants were collected across six treatments. The between subject treatments, which had an equal number of male and female participants, were a control condition with only a compass, a control condition with a paper map available prior to maze traversal and four experimental conditions consisting of combinations of egocentric and exocentric maps, and a continuously on and on demand map display. Data collected from each participant consisted of time to traverse the maze, percent of the maze covered, estimations of Euclidian distance and direction, estimations of Cardinal direction, and spatial recall.

It will help guide the Council’s Gullies “Tracing the Streams” existing programmes and resources for Mt Victoria over the next 10 years. The Master Plan looks at landscape, future plantings, and management of The streams associated with Mt Victoria/Matairangi now flow in the piped stormwater network. These were once renowned by Māori for their good pines, as well as recreation development and ways to reduce user conflict. quality water, and supported the growing of kumara on terraces across the west-facing slopes of Mt Victoria/Matairangi that now hold houses. Tracing these streams up the valleys to their catchments reveals moisture-rich gullies. Key Recommendations The Mt Victoria/Matairangi Master Plan proposes to replant these using plant mixes that include a dominant tree species. The gullies will provide a positive on-going focus for revegetation groups and, once established, will assist wayfinding through identity and narrative within Mt Victoria/Matairangi. It is important to consider the landscape values and character of Mt Victoria/Matairangi within the context of the whole Wellington Town Belt, local parks, and the Outer Green Belt. Ecologically, it provides valuable connections for native flora and fauna across the wider city.

  • CHAPTER 7 Wayfinding
    30706 07 pp227-254 r2jm.ps 5/13/04 5:51 PM Page 227 CHAPTER 7 WWayfiayfindingnding In this chapter, we discuss the 3D interaction task called wayfinding. As we saw in the introduction to Part III, wayfinding is the cognitive com- ponent of navigation. Here, we look at the psychological foundations of wayfinding, techniques and principles for supporting users’ wayfinding in 3D environments, and the connection between wayfinding and travel techniques. 7.1. Introduction We can define wayfinding as follows: Wayfinding is the cognitive process of defining a path through an environment, using and acquiring spatial knowledge, aided by both natural and artificial cues. Wayfinding is a common activity in our daily lives. We move through real-world environments, such as cities, buildings, and road- ways, for the purpose of reaching a destination or perhaps simply to ex- plore. Wayfinding tasks can be as easy as visiting the bakery around the corner or as difficult as finding a specific address on a back road in an un- known neighborhood. 227 30706 07 pp227-254 r2jm.ps 5/13/04 5:51 PM Page 228 228 Chapter 7 Wayfinding 1 Wayfinding is often an unconscious activity—we move from one 2 point to another without actively considering that we are finding our 3 way through an environment. When we get lost, however, wayfinding 4 may come to the forefront of our attention. 5 Many different types of information help us to perform wayfinding 6 tasks. Landmarks such as a church, or specific items in a building such as 7 the soda machine, may help us decide which way to travel.

  • Geocaching and the Global Positioning System GEOGRAPHY
    GEOGRAPHY 391 - A02 UNIVERSITY OF VICTORIA Summer TERM 2016 COURSE OUTLINE Geocaching and the Global Positioning System Instructor: Jessica L. Fitterer Office Hours: By appointment Office Location: DTB A247 Contact: [email protected] Teaching Assistant: Gillian Harvey ([email protected]) Class Time: Monday-Friday, 9:30 am – 4:20 pm (including 1 hour for lunch) Classroom: COR A229 Labs: DTB A251 Exam: Location TBA: Friday, August 19 2016, 9:30 am – 11:20 am COURSE DESCRIPTION In May, 2000, the United States government removed “Selective Availability” – the means by which Global Positioning System (GPS) accuracy was intentionally degraded for security reasons. Overnight, the accuracy of civilian GPS systems increased tenfold. Since this time, GPS use has been rapidly integrated into all manners of daily life, including commercial, transportation, and recreational applications. One increasingly popular recreational use of GPS is the activity of geocaching, a high-tech game of ‘hide and seek’ in which users locate hidden containers using coordinates and GPS receivers. The goal of this course is to introduce students to the activity of geocaching, along with the fundamentals of GPS navigation, and GPS data collection. Emphasis will be placed on geocaching, the history and workings of GPS and associated navigation systems, map datums and coordinate systems, and basics of GPS data management. Students will gain hands-on experience operating and working with GPS units in the field, through a variety of geocaching activities and assignments. Examples of the use of GPS in geographical research will be demonstrated through lectures and readings. A final project requires students to create and hunt for geocaches on the UVic campus.
