  30. 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. 31. Initial user study Scenario Wochenmarkt at the Domplatz Saturday morning
  32. 32. Initial user study Method short informal digitally recorded interviews with 11 subjects, aged 21-56
  33. 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. 34. Prototype development 9 maps, a range of context adaptation Location global  continental  city  neighborhood Time static  weekly  daily  hourly
  35. 35. • Temporally static • City scale
  36. 36. • Neighborhood scale • Temporally adaptive: hourly, daily, weekly
  37. 37. • Global scale • Temporally adaptive: hourly, weekly
  38. 38. • Continent scale • Daily adaptation • Global scale • Static
  39. 39. Second user study Purpose elicit user-feedback on prototypes
  40. 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. 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. 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. 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
  47. 47. Conclusions • UCD - • Paper prototypes - • Various interview techniques - • Context-adaptive maps -
  48. 48. Conclusions • UCD - Good! • Paper prototypes - • Various interview techniques - • Context-adaptive maps -
