Initial user studyResults
• No one needed or would need a map.
• Positive response.
• Everyone suggested a tourist map.
• People liked the idea of a map of pubs with happy hours, a map of football games, and a map of pharmacies.
• Little feedback on temporal adaptation.

Second user studyPart I & Part II Discussion
• On-the-spot interviews reduced the number of maps considered useful.
• The favorites chosen - shopping, pubs, and world news - were the same in both studies.
• The favorite maps were context-adaptive:location neighborhood scaletime hourly/daily/weekly updates
• Clear preference for certain maps at certain times.
![Page 45: Context Adaptive Digital Maps on Public Displays](https://reader033.vdocuments.us/reader033/viewer/2022052507/558c9047d8b42a08438b4666/html5/thumbnails/45.jpg)
Requirement recommendations
• Practical content for a small screen.
• Present information that is novel, interesting, or useful enough to encourage future interaction.
• Not all novel, interesting, or useful information belongs on a map.
![Page 46: Context Adaptive Digital Maps on Public Displays](https://reader033.vdocuments.us/reader033/viewer/2022052507/558c9047d8b42a08438b4666/html5/thumbnails/46.jpg)
Requirement recommendationsThe most appealing map content adapts to context:
• large-scale map with user’s location
• presenting information when it is most relevant to the user
• possible to adapt the content to identity
