The problem/SolutionProblemSolutionLack of knowledge about exercising/workouts.Personalization of workout depending on goals.Proper tools/equipment/resources. Settings personalized goals.Customized workout plans + Tutorials for novices.Getting results report.

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

Task 1 : Profile Setup and Body Scan

Goal selection

Task 2: Learning a new exercise

If Yes was selected

If skip was selected

Task 3: Getting interactive feedback

After Workout is completed

Experimental Method: Process3 different participants.Gender wiseWorkout experience wiseGoal wiseLaid out paper prototypes screen by screen + script for voice interactionScreens differed for each participant. Video taped each participant for later analysisAsked questions/took notes.

Experimental method: participant 1MaleRarely 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.

Experimental method: participant 2Male Exercised occasionallyNot a dedicated exerciser.Goals: strength/resistance/endurance. Liked outdoor activities.Provided us insight on how a casual semi-experienced exerciser would perceive the application.

Experimental method: participant 3FemaleExercised everydayGoals: 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.

Test MeasuresMain 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. General Experimental Results3/3 Easy to understand and had a good flow. 2/3 Touch over Voice (Although both convenient). 3/3 Voice feedback was helpful.

Task 1 resultsProfile set up and body scanParticipant 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

Task 2 resultsLearning new exercises (Tutorials).

1/3 Skipped tutorial and went straight for the stretch.2/3 Said tutorial was helpful / easy to understand3/3 Enjoyed performing the task. Voice feedback was amusing / helpful

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 test3/3 questioned the purpose of X on last screen.3/3 understood purpose and found it useful/ innovative. Suggested UI changes Removing X from last last screen-redundant. Being thrown back to the goals menu after choosing one goal was confusingDrop down menus instead of popups.Having a status button to click on instead of saying status.
