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

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
