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

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

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

patients hand-eye coordination Patients needs Age 4-10 mental
capacity of 4-6 More engaging/attractive device

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

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

Magnet & Reed Switch Testing Tested 8 different magnets, 5
reed switches Objective: At least 2 Turn-On Distance Test
Setup:
User Feedback System Design Placed in front of the user,
indicates speed relative to threshold According to our therapist,
important factors: Different colors No red color Does not get in
way of machine
Additional Semester Progress Summary Microcontroller
