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
![Page 29: LO-FI PROTOTYPING AND USABILITY TESTING Michelle Yee| Issam Lamsili | Elly Searle | Blake Thomson CSE 440.](https://reader030.fdocuments.us/reader030/viewer/2022032800/56649d2e5503460f94a05acb/html5/thumbnails/29.jpg)
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!
