AFTER WORKOUT IS COMPLETED

Slide 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.

Slide 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.

Slide 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.

Slide 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.

Slide 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.

Slide 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.

Slide 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

Slide 20

TASK 2 RESULTS LEARNING 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

Slide 21

TASK 3 RESULTS GETTING 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.

Slide 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.
