  2. 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.

  3. Architecture block diagram 3

  4. Status Update • 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

  5. Eye Candy

  6. 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

  7. Software Architecture 8

  8. 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

  9. Tentative Schedule • 2/25/07 - ADC Channels • 3/04/07 - Multiple Tmotes • 3/11/07 - Spring Break! • 3/18/07 - Gesture Recognition • 3/25/07 - Sound Support++ • 4/01/07 - Gesture Recognition Part 2 • 4/08/07 - Multiple Instruments • 4/15/07 - Testing • 4/22/07 - Debug • 4/29/07 - Polish
