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

Use Cases
18-549 Team 1: Reflex Project Presentation1/18/2007 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?)
