Context Adaptive Digital Maps on Public Displays

The document discusses context-adaptive digital maps for public displays. Two user studies were conducted to determine preferred map content and the effect of context. The first study found that tourists maps and maps of pubs, pharmacies, and football games were preferred. Prototypes were then developed adapting to location, time, and identity. A second study showed shopping, pubs and world news maps were favorites, especially when adapted to neighborhood scale and daily/weekly updates. Recommendations included practical small-screen content that encourages interaction and adapts to context like user location and timing of relevant information. The studies demonstrated the effectiveness of techniques like user-centered design, paper prototyping, and context-adaptive maps.

- 30. Initial user study Purpose determine the types of maps pedestrians would like to have displayed and the effect of context on map content
- 31. Initial user study Scenario Wochenmarkt at the Domplatz Saturday morning
- 32. Initial user study Method short informal digitally recorded interviews with 11 subjects, aged 21-56
- 33. Initial user study Results • 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.

- 44. Second user study Part 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 scale time hourly/daily/weekly updates • Clear preference for certain maps at certain times.
- 45. 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.
- 46. Requirement recommendations The 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
