+ 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 2

+ 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 3

+ 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 4

+ How the game runs: “Flyswat” game 1. 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 5

+ 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 6

+ 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 7

+ Games Team Designing/Improving games Database Team Designing and building the database Hardware Team Fixing issues with the Rockband drums HEC Team 3 members per team 8

+ Fly Swat Last semester improved “predictability” of Fly Swat game Our first task: Delivery Compatibility issues Created offline file Currently waiting on client feedback 10

+ Seven Areas of Hand Eye Coordination 1. 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 11

+ 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 12

+ 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

+ For example… Recall picture details Complete the picture Recall and sequence a series previously shown 14

+ Our Game Plan Similar background that lights up colors in sequence 15

+ Testing and Scoring Score total run percentage Record response time Cymbals/No Cymbals Spatial recognition 2-7 Sequences Unlimited Runs 19

+ Timeline Week 7/8: Present prototype to Venetia Gather feedback Week 8/9: Begin writing game code 20

+ 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 21

+ The Rockband Drum kit 23

+ Current Use of drums Child hits the drums, response is digitally recorded Corresponds with the Flash Game Connects wirelessly to therapist’s computer 24

+ 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 25

+ Sensitivity Issues Sensitivity Pads have worn out Inconsistent data recording Only certain areas on pad work This is very inconvenient for therapists and patients 26

+ 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 27

+ Solution 1 Replace sensor with a switch Place arcade buttons under pads instead of a sensitivity pad Drum shape maintained Issues: size of buttons 28

+ Solution 2 Replace current sensitivity pad with professional Piezo transducer Has a very long lifespan Issues: Expensive 29

+ 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 30

+ S Team Leader: Sagar Govani Members: Allison Wood, Joey Frechin, Lior Ben- Yehoshua, Katie Sandlin, Jessica Place V AT BALL

+ 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 34

+ 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 35

+ 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 36

+ Testing Facilities – Basement Hallway 37

+ Progress of the BALL Team Project started in the Fall of 2010 Research was conducted Initial testing Completing research Finalizing materials Prototyping Project Management Structural Design Wireless 38

+ 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 39

+ Current Project Progress Last semester ended with the research phase Additional research Preliminary design concepts First prototype First round of testing 41

+ Preliminary Design Concepts 1: Protective case 2: Foam Ball 3: Foam Layer 4: Outer Layer

+ Layer 1: Protective Case Criteria: Protective Easy to access inside Retains its shape Durable Signal can transmit through layer Current Ideas Wiffle Ball Plastic Trinket Box 43

+ Layer 2: Foam Ball Criteria Easy to access inside Retains its shape Durable Signal can transmit through layer Current Ideas Poof Foam Ball 44

+ Layer 3: Foam Layer Criteria Easy to access inside Retains its shape Durable Signal can transmit through layer Current ideas Tru Foam sheet 45

+ Layer 4: Outer Layer Criteria Easy to access inside Retains its shape Durable Signal can transmit through layer Waterproof Current Ideas Outdoor soccer ball Starter soccer ball Jumbo tennis ball 46

+ Enclosing Materials Criteria Allows easy access Durable Keeps inside layers together Seals outer layer Current Ideas Sewing Velcro Hot glue 47

+ Possible Structural Design Materials Left: 2 - Foam Ball Center: 4 - Large Tennis Ball Right: 2 - G2 Air Small Ball 48

+ Ball Materials (continued) Left: 4 - Starter Soccer Ball Right: 4 - Mitre Cup Final Soccer Ball 49

+ Testing Procedures Let a soccer team kick the ball around Local house league team Actual testing case Campus pick up game Extreme testing case Drop Test Build a machine that drops soccer ball from the same height Repeat multiple times for accurate results 50

+ Testing Procedures Test in extreme conditions for durability A simple LED circuit will replicate if protective casing protects the accelerometer 51

+ Testing Procedures Give prototype to team Observe game/practice Count number of times ball is kicked At the end, check if LED is still on 52

+ Wireless Transmission Overarching goal for Fall semester 2011 Design & construct working prototype Component goals Acquire most fitting accelerometer Build intra-ball circuit Achieve wireless transmission to handheld device Log acceleration data; calculate & output force values 54

+ Components Required Accelerometer with transmitter Handheld device or laptop Batteries, in holder 55

+ Accelerometer Criteria Measure acceleration in all 3-axis (X,Y & Z) Very small & lightweight Small power consumption High sensitivity Low cost Brands being considered Analog Honeywell 56

+ Data Acquisition LabVIEW User friendly Faster to develop program Measurement application Acquire acceleration values 57

+ Data Acquisition (continued) Calculate force values Display output on handheld device Develop scale suitable for Suba 58

+ Handheld Device/Laptop Suba may get an iPad iPad can run software & receive wireless data Must provide handheld device if no iPad Be able to install LabVIEW runtime environment Be able to run executables Have WiFi capabilities Data loggers Cost is not justifiable ($1000+) 59

+ Question and Answer Session Would this overall concept/model be appropriate for therapy sessions? Are there any other design criteria that you think is important to include? Any suggestions or modifications you see should be made? 60
