  2. Agenda • Project Description • Customer Needs • Engineering Specifications • Concept Summary • System Architecture • Design Summary • System Testing Results • Objective Project Evaluations • Suggestions for Future Work

  3. Project Description • Seated balance to help physical therapist teach wheel chair bound patients to improve the strength of their core muscles. • Currently have a tower that is built that has seven large panels in a vertical line that are separated by banks of 3 tri-colored LEDs. • When activated the LED’s will be blue, if the patient touches the target they will turn green and if they miss they will become red. • There are two games in the MCU : Random & Timed Trial • Second tower will be added to the game to add more challenges for the patients. This tower will be a slave to the first tower and help to increase a patients side to side reaching distance.

  4. Customer Needs

  5. Engineering Specifications

  6. Concept Summary • MSP430 Board • Functional Reach • Wireless

  7. System Architecture

  8. Design Summary • Software • PCB

  9. System Testing Results

  10. Demo • Turn tower on • Select game via user input buttons • For random: • Chose time of each round • # of rounds • For sequence: • Chose time of each round • # of rounds • Press any key to start • Results displayed, hits, misses after completion • Option to play again

  11. Objective Project Evaluations:Success and Failure • Success • Functioning tower • Functional reach test • PCB • Upgrade to MSP430 + TI resources now available • Failure • Incorporation of second tower • Wireless • Automated functional reach • Not capacitive touch based • Only two games

  12. Reasons for Failures • The previous MCU used a different complier, which RIT no longer had a license for • The previous code used was not up to date on edge • The current touch plates on the towers are not capacitive touch plates, they are grounding plates, which required a comparator circuit to make work • Due to troubles encountered, the wireless was never completed and the functional reach was never automated.

  13. Suggestions for Future Work • Capacitive touch buttons • Suggested to use selected capacitive touch chip • Add additional towers • Wireless communication • suggested to use selected wireless device (eZ430-RF2500) • Automate functional reach • Create additional games • Add sound
