- 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.
- 34. Prototype development 9 maps, a range of context adaptation Location global continental city neighborhood Time static weekly daily hourly
- 35. • Temporally static • City scale
- 36. • Neighborhood scale • Temporally adaptive: hourly, daily, weekly
- 37. • Global scale • Temporally adaptive: hourly, weekly
- 38. • Continent scale • Daily adaptation • Global scale • Static
- 39. Second user study Purpose elicit user-feedback on prototypes
- 40. Second user study Part I Saturday, Domplatz showed pedestrians maps in stack, brought to phone booth, voice recorded; 7 interviewees aged 21-35

- 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
