2. Overview • Overall Problem/Solution • Representative Tasks • Lo-Fi Prototypes • Experimental Method/Results • Suggested UI Changes

3. The problem/Solution

4. 3 Representative Tasks • Profile Setup and Body Scan. • Learning new exercises (Tutorials). • Getting interactive exercise feedback.

5. IntroDuction Screen

6. Task 1 : Profile Setup and Body Scan

7. Goal selection 

8. Task 2: Learning a new exercise • 

9. If “Yes” was selected

10. If “skip” was selected

11. Task 3: Getting interactive feedback

12. After Workout is completed

13. Experimental Method: Process • 3 different participants. • Gender wise • Workout experience wise • Goal wise • Laid out paper prototypes screen by screen + script for voice interaction • Screens differed for each participant. • Video taped each participant for later analysis • Asked questions/took notes.

14. Experimental method: participant 1 • Male • Rarely exercised • Goals: balance, coordination, endurance. • Provided us insight on how new exercisers would see the learning an exercise task (tutorial) which is mainly targeted at them.

15. Experimental method: participant 2 • Male • Exercised occasionally • Not a dedicated exerciser. • Goals: strength/resistance/endurance. • Liked outdoor activities. • Provided us insight on how a casual semi-experienced exerciser would perceive the application.

16. Experimental method: participant 3 • Female • Exercised everyday • Goals: endurance. • Liked running/core workouts. • Provided valuable feedback on how experienced users who may know much of the information presented perceive the value of the application.

17. Test Measures • Main concern: ease of voice vs. touch interactions. • Kept track of users looking confused during the interface flows. • Kept track of how long tasks took and if they were intuitive. • Voice vs. Touch preferences. • Asked questions at the end about hybrid interface.

18. General Experimental Results • 3/3 Easy to understand and had a good flow. • 2/3 Touch over Voice (Although both convenient). • 3/3 Voice feedback was helpful.

19. Task 1 results Profile set up and body scan • Participant 1: Body scan was awkward. • Participant 2: Knew how to use body scan and pick goals immediately. • Participant 3: Performed it fine but had some issues with picking goals

20. Task 2 resultsLearning new exercises (Tutorials). • 1/3 Skipped tutorial and went straight for the stretch. • 2/3 Said tutorial was helpful / easy to understand • 3/3 Enjoyed performing the task. Voice feedback was “amusing” / “helpful”

21. Task 3 resultsGetting interactive exercise feedback. • 3/3 understood how to get body status feedback/ used it well. • 3/3 Clicked home page button to complete the test • 3/3 questioned the purpose of “X” on last screen. • 3/3 understood purpose and found it useful/ innovative.

22. Suggested UI changes • Removing “X” from last last screen-redundant. • Being thrown back to the goals menu after choosing one goal was confusing • Drop down menus instead of popups. • Having a “status” button to click on instead of saying “status”.
