  1. 18-549 Team 1: ReflexProject Presentation System Architecture Use Case Reliability Inbae Lee (inbaelee@cmu.edu), Paul Thurlow (pthurlow@andrew.cmu.edu), Ryan Frishberg (frish@cmu.edu), Siva Srinivasan (siva@cmu.edu)

  2. Re-cap: Concept • Gaming Glove • wearable glove which detects hand movements for use as an input device • Accelerometer data to tell hand movement and the Telos Mote to wirelessly communicate • What’s New • Force Sensor Resistor: button on the thumb • Flex Sensor: finger flex detection

  3. System Architecture Processed Data Sensor Data Raw Data Process Data

  4. State Transition Diagram

  5. Use Cases

  6. Risks & Mitigation • “We lost data during communication”: Disregard, or guess with ‘before & after’ • “We don’t know how to talk to Wii”: Just talk to laptop (or beg Nintendo for help) • “We can’t get the flex sensor to cooperate”: Use the one with pre-made board instead • “Reflex is too slow & laggy”: Optimize code or limit functionality • “Our sensors aren’t sensitive enough”: Hmm…(target the elderly?)

  7. Questions? What our glove might look like (plus all the wires) Flex sensor (on the index finger)
