Initial user study

Purpose determine the types of maps pedestrians would like to have displayed and the effect of context on map content

Initial user study

Scenario Wochenmarkt at the Domplatz Saturday morning

Initial user study

Method short informal digitally recorded interviews with 11 subjects, aged 21-56

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.

Prototype development

9 maps, a range of context adaptation

Location global continental city neighborhood

Time static weekly daily hourly

• Temporally static• City scale

• Neighborhood scale• Temporally adaptive:

hourly, daily, weekly

• Global scale• Temporally

adaptive: hourly, weekly

• Continent scale• Daily adaptation

• Global scale• Static

Second user study

Purpose elicit user-feedback on prototypes

Second user study

Part I Saturday, Domplatz showed pedestrians maps in stack, brought to phone booth, voice recorded; 7 interviewees aged 21-35

Part II Results

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.

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.

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
