  1. HandTalk April Fools! Jorge Hemant Bhargav Wesley

  2. Status Update New Sensors – no analog circuit needed! Reading user dictionary data from microSD card Have plan for wiring and powering glove Wesley’s roof is OK!

  3. System Architecture Glove Sensors Raw Data Bluesentry Device A2D QuantizedData Bluetooth Module Bluetooth Packets Cellphone HandTalk Midlet

  4. Demo! I’m with stupid

  5. Test Cases • BlueSentry Lost Connection Test • BlueSentry Power-Off Test • SD-Card Reading Test • Wrong User Input Test • Add/Delete Word Test • Start-Stop-Start Cycle Test • Actual Battery Life

  6. Metrics • Recognition Accuracy • The ability of the system to accurately detect a sign made by the user • We will measure this by having an impartial user sign 10 predetermined symbols and record the amount of times the symbol was recognized as correct • System Latency • Measured system startup time from initiating connection to output on screen • Loaded Dictionary from SD card each time before initiating connection

  7. Initial Results
