PROJECT CONCEPT

^ back to top

Develop a glove that can be used as a controller for a game system such as the Nintendo Wii. Primarily using accelerometers, the glove will sense the motions that its user makes to allow for a more realistic interaction and gaming experience. The project is aiming for a successful demonstration of the concept and an implementation that could drive the future of gaming.



MOTIVATION

^ back to top

Most game controller systems involve the use of joysticks or some basic motion detecting capability to enhance gaming experience. Instead of holding a controller and pressing the buttons for input, users can wear the glove and perform comfortable, natural motions to provide more realistical input.

IMPLEMENTATION DETAILS

^ back to top


A bare-bone Telos Mote, and our modification with 1) the connector pins that would easily connect and disconnect to the wire. The entire board is wrapped up with paper so that static electricity will not affect the integrity of the chips when inserted into the elastic pouch.





This elastic pouch on an arm band will holster the modified Telos Mote, with cut-outs for easy access to the connector pins, push buttons and the LED status display.





The glove is mounted with 1) force sensors on the tips of the index and the middle finger, 2) a flex sensor on the ring finger, 3) the accelerometer chip on the back of the hand and 4) wiring and connectors to the Telos Mote.
