1. LO-FI PROTOTYPING AND USABILITY TESTING Michelle Yee| Issam Lamsili | Elly Searle | Blake Thomson CSE 440

2. Problem - Solution Problems  Not enough exercise  Working out  too much time & planning!  Driving  pollution Solution  Integrate more steps into your day  Plan your daily activities around your walking goal

3. Mission Statement  Design an application that encourages people to exercise more, drive less, and to explore the area around them

4. Overview  Representative tasks  Lo-fi structure  Scenarios  Experimental method  Experimental results  Suggested UI changes  Conclusion

5. Representative tasks 1. Set a personal walking goal 2. Figure out how to walk more 3. Achieve a daily walking goal

6. Prototype structure Screens Combo boxes Text fields & buttons Keyboard Slider

7.  Just downloaded the application Scenario 1- set personal walking goal

8.  Collecting information… Scenario 1- set personal walking goal

10. 24 hours later… Scenario 1- set personal walking goal

11.  Enough information on your walking habits 7500 Scenario 1- set personal walking goal

12.  Goal set! Scenario 1- set personal walking goal

13.  Just arrived to Safeway… Safeway Scenario 2- figure out how to walk more

14. Next Wednesday…

15.  Reminder Scenario 2- figure out how to walk more

16.  More steps Scenario 2- figure out how to walk more

17.  Walking… Scenario 2- figure out how to walk more

18.  Route map Scenario 2- figure out how to walk more

19. Scenario 3-achieve a daily walking goal  Check progress

20. Scenario 3-achieve a daily walking goal

23.  Display results Scenario 3-achieve a daily walking goal

24. Select a route Scenario 3-achieve a daily walking goal

25. After some walking… Scenario 3-achieve a daily walking goal

27. 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

28. 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

29. 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

30. 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!
