Project Concept & Motivation Concept - Our project will allow users to play

virtual musical instruments. The prototype uses embedded components to detect and communicate user gestures, via Zigbee, to a base station that plays the appropriate sound.

Motivation - Intuitive virtual instruments that allow multiple musicians to play together do not exist. Our prototype will allow players to have jam sessions on a gesture controlled device capable of simulating several instruments.

Identifying different gestures Two accelerometers on one Tmote

- Getting ADC to work Accuracy of accelerometer data IEEE 802.15.4 Interference Handling multiple Data streams from

multiple Tmotes Sound Library

Next Steps Input from multiple ADC channels

One for each axis on each accelerometer Input from two accelerometers per mote Multiple instruments Improved gesture recognition

Lessons Learned Don’t confuse sensors. Bluetooth is unnecessary when you

have a wireless protocol Thick wires don’t bend well. No one likes nesC

Not even the creators
