Design Review April 27, 2010

1. Design Review April 27, 2010

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

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

4. The SVAT Team • Advisors: • Theresa Gordon • Darryl Dickerson • Team Teaching Assistant: • Nate Cooper • Team Leader: • Gregory Pajot • Project Leaders: • Lisa Jasinski – AAC Team • Michael Coots – HEC Team • Gregory Pajot – Bike Team

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

6. Augmentative AlternativeCommunication(AAC) Design Review-Spring 2010 Lisa Jasinski Shyam Naidu SVAT – AAC Team

7. AAC is in the “Service and Maintenance” Stage

8. Service & Maintenance • Fixing previously delivered project • Improving • Making sustainable

9. History • 2006 AAC created the site • Problem: Need cheap personalized communication tool • Specifications: • Inexpensive • Accessible • Customizable • Identified solution: Web site patient communication

10. History Continued… • Web site pro’s: • Inexpensive • Accessible • Personalization • St. Vincent’s lost funding • Links, pictures, & codes were lost or missing

11. Previous Teams Design • Login Page • Customized features: • Number of options per page • Types of options • Custom Pictures • Custom Sounds

12. Previous website

13. Old Website: Flow Sub Category 1 Audio 1 Option 3 Sub Category 2 Audio 2 Sub Category 3 Audio 3 Sub Category 1 Audio 1 Option 2 Sub Category 2 Audio 2 Sub Category 3 Audio 3 Login Main Page Sub Category 1 Audio 1 Option 1 Sub Category 2 Audio 2 Sub Category 3 Audio 3 Number of Options Preferences Photos Personalize Audio Type of Options

14. Currently • AAC Spring 2010 starting over • Learned PHP & MySQL • Created basic website with multiple working strings • Located old files

15. Currently Recreated login Recreated add/delete user(s) Used index(s) for different pages Combined database to condense Enabled some preferences

16. First set of options

17. If we select Books

18. If we select Story Books

19. Sound File

20. Current: Website • http://epics-wiki.ecn.purdue.edu/svat/backup2/login.php • http://epics-wiki.ecn.purdue.edu/svat/prompt.php

21. Timeline

22. Future • Ability to personalize: • Personal photos • Personal sounds • Choose # of options • Choose type of options • Possible: Add ability to create sentences at different levels

23. Delivery • We currently have a working prototype of the website • Will be updated • Website with personal preferences: December 2010 • Brainstorm on website with sentence creation feature: December 2010 • User manual with coding comments: December 2010

24. Sustainability • Why will this not be lost? • User Manual • Code Manual: Comments for code & guide for restoring site if everything is lost

25. Sustainability • Documentation of location of files on EPICS server • Find server that backs up • Provide information for how to back up regularly

26. Transitioning Mini-Lab to teach MySQL & PHP to future EPICS students Condense number of files and locations of needed pages

27. Question?

28. Bike Project Team Spring 2010

29. Introduction • PROJECT LEADER • Gregory Pajot – Senior, Computer Engineering • TEAM MEMBERS • SauravBehl – Junior, Electrical Engineering • Collin Ramsey – Freshman, First-Year Engineering • Hyunwoo Shin – Junior, Electrical Engineering

30. 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

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

32. 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 • User Feedback System indicates the patient’s speed relative to the threshold • If threshold maintained, TV stays on • If not, TV turns off

33. Brief History • Project began in Spring 2008 • A functional prototype was delivered in Spring 2009 • Proof-of-concept • Feedback received and redesign began in Fall 2009 (last semester)

37. Our Therapist’s Wish List • Portable and adaptable • Works on a variety of equipment • Can move from equipment to equipment • Can move from facility to facility • Easy to “install” • Easy to operate

41. New Design Concept

42. User Feedback System • A series of LEDs that indicate the patient’s speed • Key design factors: • LED brightness and viewing angle • LED colors • Ease of attachment and transport • Durability

46. PCB

49. Motherbox

50. Counterweight • Necessary due to the weight of the steel gooseneck
