VA THEC
2+Our Project Partner
St. Vincent Pediatric Rehabilitation Center
In Indianapolis, Indiana
Working with physical therapists Patients are children ages 3-14 years old
struggling with motor and visual skills
3+Project Goal
Develop a method of testing, recording, and quantifying a patient’s hand eye coordination skills
Quantified data will be used by physical therapists to track patients’ improvement with therapies
Needs to be done without patients feeling like they are being tested, but gives an incentive for them to try to do their best
4+Current Design
A system of fun games which challenge a child’s hand eye coordination skills
Child does not know data is being recorded
Data is quantified and easy to understand
5+How the game runs:“Flyswat” game1. Child sees a moving fly
2. The fly lands on a colored spot
3. Child hits the drum with the corresponding color
4. The time it takes for the child to respond and hit the drum is quantified as a measure of their Hand-Eye Coordination ability
6+Project History
HEC project began in Fall 2010
Games have been developed in past semesters
The Rockband drum hardware was selected early on
Data is currently recorded manually
7+Current Project Status
Therapists want new games to be developed
Old games need improvements/debugging
Rockband drum kit has serious hardware sensitivity problems that need to be fixed
Digital database needs to be designed and created

Fly Swat• Last semester
improved “predictability” of Fly Swat game
• Our first task: Delivery
• Compatibility issues• Created offline file• Currently waiting
on client feedback
+ 11
Seven Areas of Hand Eye Coordination1. Visual-Spatial Relations: uses sight to
discriminate differences
2. Visual Memory
3. Visual Discrimination
4. Visual Figure Ground
5. Visual-Form Constancy
6. Visual Sequential Memory
7. Visual Closure
12+Developing A New Game
• The client wants a game to test the child’s visual memory
•Similar to the Fly Swat game:• Same drum kit• Similar layout
13+What is Visual Memory?
The ability to store and retrieve previously experienced visual
sensations and perceptions when the stimuli that originally evoked them
are no longer present.

Testing and Scoring
• Score total run percentage• Record response time
Cymbals/No CymbalsSpatial recognition
2-7 Sequences
Unlimited Runs
20+Timeline
•Week 7/8:• Present prototype to Venetia • Gather feedback
•Week 8/9:• Begin writing game code
21+Questions• Are there any suggestions for the criteria involved in the new
game?
• Is there anything you would like to ask us?
Current Criteria: • Unlimited runs • 2-7 sequences• Cymbals/no cymbals• Score
percentage of total runs• Record response time

23+The Rockband Drum kit
24+Current Use of drums
Child hits the drums, response is digitally recorded
Corresponds with the Flash Game
Connects wirelessly to therapist’s computer
25+Successful Ergonomics
Children can easily figure out how to use the drum kit
Therapist does not need to explain much
Children love the drum kit design
26+Sensitivity Issues
Sensitivity Pads have worn out
Inconsistent data recording
Only certain areas on pad work
This is very inconvenient for therapists and patients
27+Redesigning the Drum kit
Determined the sensitivity problem unfixable without major altering
However, want to keep drum kit layout Ergonomics are too valuable to loose
28+Solution 1
Replace sensor with a switch
Place arcade buttons under pads instead of a sensitivity pad
Drum shape maintained
Issues: size of buttons
29+Solution 2
Replace current sensitivity pad with professional Piezo transducer
Has a very long lifespan
Issues: Expensive
30+Plan for the semester
1. Research solutions to sensitivity issues
2. Choose and implement a solution
3. Deliver fixed product to client
Even if permanent solution is not made this semester, we need to have at least a temporary working drum kit delivered

34+Project Identification
Direct user: Jennifer Suba – therapist at St. Vincent’s Carmel location
To design a ball with a inner device that tracks and records the progress of patients during a therapy session
35+Specifications and Requirements
Requirements: Resemble a soccer ball Durable Record the progress At least 5” in diameter Portable Easy to use Patients should not know they’re being
tested
36+Operational Overview
Suba places the ball on the
ground
Patient kicks the ball down
the hall
The accelerometer picks up the impact force
Sends it to wireless handheld
device
Data recorded
Repeat for 5-10
minutes

39+Project Timeline
Week 8: Have all materials and begin building prototypes
Week 10: Run first round of prototype testing
Week 11: Analyze test results and begin modifications
Week 12: Run second round prototype testing
Week 13: Analyze test results and continue modifications
Week 15: Have a prototype ready for delivery at the beginning of the Spring Semester
