  1. April 9th, 2010 SDP10 – Final Project Review Motion Analyzer for Physical Therapy (MAPT) Arjuna Baratham (CSE) - Sean Klaiber (EE) - James Rutter (EE) - Constantina Tyes (EE) Professor Soules Advisor, Senior Lecturer, ECE

  2. Outline Demonstration Key Design Components Design Review Complete Design Overview

  3. DEMONSTRATION

  4. Outline Demonstration Background Key Design Components Complete Design Overview Future + Timeline

  5. Problem and Solution Reliable Quantitative Data in Physical Therapy (PT) can only be Collected with a One-on-One Patient/Therapist Interaction Create a simple,inexpensive, and portable device that can accurately measure physical therapy related motion

  6. Block Diagram

  7. FPR Deliverable • 2 PCB WS working • PSFD communicating with the user • PCB and enclosures for wireless sensors and PSFD • PT software

  8. Outline Demonstration Background Key Design Components Complete Design Overview

  9. Mounting Wireless Sensor • Housed in a lightweight plastic enclosure • 3.125”x2”x0.875” weighing about one pound • Two sensors comfortably • mounted above and below knee • Pouch and strap designed for • holding cell phones for • horseback riders

  10. Manufacturing PCB • All PCBs made by students • Front and back of sensor pcb shown below

  11. Outline Background Key Design Components Demonstration Complete Design Overview Timeline

  12. PT Software • Audio Updates/Additions • Viewing of Exercise Charts • By Demo Day: Textual Summary of Exercise Data

  13. Processing and Display • Counterpart XBee wireless receiver plugged into USB on BeagleBoard • All data values plus timestamp logged into .txt file • Python script on Beagleboard processes received sensor data • Real-time feedback • Sends Arduino commands to interact with visual feedback • Playback of audio cues that were recorded by PT • Data Logging • Stores all received data with single header • Java GUI can plot and organize all of the logged data

  14. Exercise Scripts • Data Rate: 60 Packets per second (per sensor) • File System: • Script Files in /script/ • Data Files in /data/[exercise name]/ • Audio Files in /PT Audio Data/[exercise name]/

  15. PSFD : Input/Output • Python – Listen Script upon Beagle Startup • Arduino/BeagleBoard exchange simple serial messages • Audio feedback – limited use • 7 Segment LEDs – low power, high visibility

  16. Finances Already purchased: Anticipated costs:

  17. Team Roles • Sean • PSFD output, PT java GUI, • PCB production • James • PCB production, PSFD input, closure design • Arjuna • Wireless data Tx/Rx, Python exercise scripts • PT java GUI • Constantina • Wireless sensor design • PCB production
