EYES-FREE FITNESS Design Concept Abstract Demo Implementation Design Iterations Final User Testing Results & Feedback Analysis & Design Review Conclusion Problem:
Hard to input workout data
Lack of motivation to improve workouts
SOLUTION Eyes-Free Feedback Accelerator-based Feedback Set Goals & Track Progress Voice based motivation & feedback Eyes-Free Exercise App “Eyes free is good. But adding workout details is just not intuitive”
Eyes-Free Exericse App
+ Gesture based input
“What’s the point of having
an app if I just don’t improve”

Eyes-Free Exericse App
Gesture based input
+ Adding objects/flowers
/furniture to motivate homepage

“Do you really think that adding furnitures to my virtual house or having flowers is really going to motivate me??”


Eyes-Free Exericse App
Gesture based input
+ Voice Based Motivation through
out the time of working out


“I like the motivation, but I will like a more streamlined and guided approach" Eyes-Free Exericse App
Gesture based input
Voice Based Motivation through
out the time of working out
+ Algorithm for auto-setting and
auto-monitoring goals & results


“I love it. But it will be nice to track progress in and see a overall preview” Eyes-Free Exericse App
Gesture based input
Voice Based Motivation through
out the time of working out
Algorithm for auto-setting and
auto-monitoring goals & results
+ Tracking progress graphs
that can be sliced/diced.



"Gestures input is good, but still slightly obstructive and makes me look weird while exercising" Eyes-Free Exericse App
Gesture based input
Voice Based Motivation through
out the time of working out
Algorithm for auto-setting and
auto-monitoring goals & results
Tracking progress graphs
that can be sliced/diced.
+ Hand's free accelerometer based
input added



"Its almost perfect. But..." Hant’s dumbell algorithm
Beginner, Intermediate, Expert algorithm
Chart library
Facebook library
Text to speech library
BUILDING ROUTINES Too Clumsy
Too many taps
Have to choose exercises one after another = not good Lesser Clicks Too many exercises in one row
Disorganised EYES-FREE
DATA LOGGING No way to see what has been added in
Hard to add big values like 40 kg or 15 reps Can add big values easily Movement is obstructive while exercising
Voice feedback is not enough for tracking GOAL SETTING No goals.
Tracking progress is not that effective if setting goals is not available. Ability to add personal goals Adding goals is very confusing
Manual adding of goals not that easy. MOTIVATION Motivation doesn't make sense
Having houses or Trees is not going to motivate us. Slightly better. But.. Adding clock, furniture or windows is still not going to motivate us. Usability Testing Post-Test Interview - conducted with 5 users, on functionality and interface design Task 1: Basic navigation
Task 2: Adding and editing of information
Task 3: Recording of exercises
the application has great features but requires some form of learnability

the design of the application is neat which encourages easy usability and memorability

the implementation of the accelerometer into a counter is potentially beneficial and interesting
- "Very good implementation of motivation & tracking workouts"

- "Steep learning curve as alot of things are new and more instructions will be helpful

- "Gestures used a intuitive and accelerometer based workout data collection is great"

- "Computer voice is a little scary rather than motivational" Compare & Contrast users - "I like the tracking, but wonder whether goals is really something which I want to use" Mr. Relax one corner Mr. Big Boy - "Goals that are more generic like losing weight, becoming a little fitter appeals more to me than setting each and every individual goals." - "Love the goals and the tracking. The accelerometer based input is very helpful"." - "I will like a little more freedom in how I set up my goals and also the weights that I use to train rather than everything being managed automatically." SUCCESSFUL DESIGN ASPECTS Customization of exercises through lists

Setting of goals based on level of expertise

Eyes-free tracking for the number of reps through accelerometer (bicep curls)

Audio feedback compensate for the lack of visual feedback while exercising

Progress charts reinforces the motivation for users to improve their performances
UNSUCCESSFUL DESIGN ASPECTS Instructions were not shown in full detail for certain functionality

Using the text to speech library for audio feedback caused monotonous voice articulation

Lack of categorization for user’s customized lists and exercises.

Goal setting confusing for new users and has a steep learning curve.

Propsed Changes Provide a help or tutorial screen for users to familiarize with the application

Provide respective instructions in short phrases among the screens to guide users

Allow categorization of exercises to facilitate easy retrieval of information for the users

Make goal setting into 2 pages so that the user can set his current exercising habits followed by goals in the 2nd page.
