  1. Developing a Context-aware Electronic Tourist Guide Keith Cheverst, Nigel Davies, Keith Mitchell, Adrian Friday, Christos Efstratiou CHI(Human Factors in Computing Systems) 2000

  2. Outline • Motivation • Objectives • System Introduction • Experiment • Conclusion

  3. Motivation • The GUIDE system has been built to overcome many of the limitations of the traditional information and navigation tools available to city visitors.

  4. Objectives • The requirements for supporting the information and navigation needs of city visitors. • The design of a customized web-browser application to meet these requirements. • An evaluation of GUIDE focusing on the quality of the visitor’s experience.

  5. System Introduction • The GUIDE system is based on a distributed and dynamic information model that is disseminated to hand-held GUIDE units using a cell-based wireless communications infrastructure.

  6. (Cont.) • Wireless Communication Infrastructure

  7. (Cont.) • The Guide Information Model

  8. (Cont.)

  9. (Cont.)

  10. (Cont.) In more detail, the visitor can touch an appropriate button in order to perform one of the following tasks: • Information retrieval. • Navigation of the city using a map. • Creating and then following a tour of the city. • Communicating with other visitors or the TIC by sending a text message. • Booking accommodation.

  11. (Cont.) Creating and Following a Tour of the City • The opening and closing times of the requested attractions. • The best time to visit an attraction, e.g. avoiding opening time if there is often a queue. • The distance between attractions and the most aesthetic route between them.

  12. (Cont.)

  13. (Cont.) Providing an Awareness of Disconnected Operation The fact that GUIDE units can cache large parts of the information model locally enables much of the system’s functionality to remain available throughout periods of disconnection

  14. Experiment • Profiles of visitors involved in the evaluation

  15. (Cont.)(1/2) • The majority (53/60) of visitors appreciated the flexibility provided by the system • When booking ticket (48/60) of visitors said that they would want some form of confirmation that the booking had taken place • Recommended ranking list • (e.g the specials menu, popular tourist spot)

  16. (Cont.) (2/2) • Preferred a smaller (PDA) sized device • while 13 said they would have preferred a thinner device

  17. Conclusion • Through our evaluation of GUIDE, we found a surprisingly high level of acceptability across a wide range of users. • GUIDE will be to utilize the growing acceptance of connected personal computing devices
