Problem - Solution
Problems Not enough exercise Working out too much time &
planning! Driving pollutionSolution Integrate more steps into your day Plan your daily activities around your
walking goal
Mission Statement
Design an application that encourages people to exercise more, drive less, and to explore the area around them
Overview
Representative tasks Lo-fi structure Scenarios Experimental method Experimental results Suggested UI changes Conclusion
Representative tasks
1. Set a personal walking goal
2. Figure out how to walk more
3. Achieve a daily walking goal

Experimental Method
Recruited 3 participants Environment: engineering annex lounge Roles: 1 moderator
1 computer
2 observers Each participant pre-test questionnaire
task book explaining 3 tasks
perform 3 tasks + thinking aloud
post-test questionnaire Test measures: incidents + reactions +
questionnaires
Experimental results
Negative Unclear home screen Needs to be more descriptive Lack of a help feature “Current route” button ambiguous Meaning of history graph unclear Remind me button too prominent Positive status bar dynamically updated “auto-learn” feature convenient
Suggested UI changes
Change home screen (include menu button)
Add help feature Make it more descriptive Titles for each screen More consistent look and feel
Conclusion
Lo-fi prototype first test for our application
Some limitations of paper prototype Some participants did not read the tasks
carefully Overall, satisfied with feedback received Ready to start working on hi-fi prototype!
