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
![Page 3: UAA Self Guided PDA Tour Edward Wickham CS470 Project Final Presentation Spring 2004](https://reader035.vdocument.in/reader035/viewer/2022072114/56649f2f5503460f94c49653/html5/thumbnails/3.jpg)
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.)

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.)

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

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

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
