Design Review March 2, 2010

Slide 2

Our Partner: The St. Vincent Pediatric Rehabilitation Center Located in Indianapolis Services Provided (Outpatient): Occupational Therapy Physical Therapy Speech-Language Pathology Audiology Each of our project teams work with an individual therapist to create designs that will aid them and also their patients

Slide 3

Our Partner: The St. Vincent Pediatric Rehabilitation Center Difficulties they are facing: Budget cuts and lack of funding Much of what they already have was provided through grants Cannot purchase new equipment on their own or even fix things that are broken In the winter, the children need to have coats on because heating the entire building is too expensive The therapists need new tools to help them provide quality care for their patients This is where we come in

Slide 5

The Projects 1. Augmented Assisted Communication (AAC) A website that aids patients with special communication needs 2. Hand-Eye Coordination (HEC) Measuring how fast a patient can react and how accurate their reactions are 3. Bike A device that is attached to an exercise machine that will monitor its speed and turn off a TV if the patients RPM drops below a threshold set by the therapist

Slide 28

Estimated Delivery Date: May 2010 EPICS Design Process

Slide 29

Therapists Needs Measure hand eye coordination with quantitative data Reaction time= fly stops on pad to when child hits pad. % of correct hits Differences between current and new methods. Current Boring Unattractive New device Engaging Entertaining

Slide 42

Partner Need Quantitative measurement when using exercise devices Indicate progress for insurance and doctors Need duration of therapy, and total repetitions/revolutions Motivation for the therapy patient

Slide 43

Partner Need Issues with measuring quantitatively: The exercise equipment they have are hand-me- downs Cant afford to buy new equipment Some of their exercise equipment does not have electronic functionality Others do, but are broken Cant afford to fix the broken electronics Currently, Suba has to count revolutions in her head and use a stopwatch

Slide 44

Project Overview A device attachable to exercise equipment Quantitative Measurements: Times the duration of exercise Detects and counts revolutions Motivates the patient: Therapist sets a threshold value for the patients speed If threshold maintained, TV stays on If not, TV turns off

Slide 45

Brief History Project began in Spring 2008 A functional prototype was delivered in Spring 2009 Proof-of-concept Feedback received in Fall 2009
