  1. UAA Self Guided PDA Tour Edward WickhamCS470 Project Final Presentation Spring 2004

  2. Purpose • Provide new students and parents with an alternative/supplement to Orientation tours • Explore technologies for using a Personal Digital Assistant (PDA) in a Self Guided Tour

  3. Requirements • Begin and go anywhere (Active Tour) • Use PDA Format – Palm, Pocket PC • Deliver to UAA-owned and personal PDAs • Include Visual and Text Navigation • Provide information • Physical (Buildings, Landmarks, Services) • Contextual (Departments, anecdotes, etc.)

  4. Project EstimatesThe Project Uncertainty Principle

  5. Analysis Questions • What is the nature of the data? • Effectively static • BUT! • Presentation formats are dynamic (Screen size, color depth, etc.) • Data categories are inter-related (Buildings, Departments, etc.)

  6. Final, Flexible Solution • AvantGo Channel and its PDA based web browser provides for a ready made presentation and delivery platform • Database provides for easy content maintenance • Coldfusion application provides for consistent page presentation and dynamic content generation. • Support for new devices is achieved by adding additional graphics, changing one file (agHTTPheaders.cfm) to map the device to the graphics directory. • Support for the ColdFusion application can be provided by UAA IT Department

  9. Application.cfm agHTTPheader.cfm Data Extraction Layer Content Menu bar Common Page Architecture Uses Color Depth and Screen Resolution data in HTTP Header to determine graphics directory Uses URL variables to determine data detail level Uses data to dynamically construct content as well as new URLs

  10. Database Schema

  11. Map to North Home - Buildings - Departments - Map to East Services - Points of Interest - Information - Zoom out - Map Detail Buildings, Departments, Services and Points of Interest Links Display information specific to displayed map

  12. Summary and Detail Pages

  13. Lessons Learned • Never oversimplify requirements. • Even with relatively static information, dynamic presentation is always better when dealing with large amounts of similarly formatted information. • Presentation on a PDA is more difficult than it looks

  14. Conclusion • Delivered prototype Campus Tour on PDA • Used AvantGo Channel and PDA based browser • Provided a database and a ColdFusion web-based application to drive a dynamically generated Campus Tour
