Presentation Transcript

  1. AirBand Glove System March 10, 2009 ECE 4007 L03 Aaron Kane Roth Fralick Jason Zutty

  2. AirBand • Emulates playing musical instruments through natural gestures. • Shows the potential of an extensible system. • Costs significantly less than current market. • Uses in consumer electronics and HCI research.

  3. Design Goals • Extensible architecture. • Standard MIDI output. • Intuitive operation. • Marketable product.

  4. Data Glove • Baseball batting glove. • Induction based sensors. • Coils consist of magnet wire. • Coils on inside of hand. • 3 coils per finger. Figure from [1]

  5. Sensor Positions Figure edited from [1]

  6. Embedded System • PCB connected to glove wrist. • Atmel ATMega1284P microprocessor. • Crystal Oscillator creates generator signal. • Time division modulated measurements across fingers. • Digital signal Outputs.

  7. Embedded System Block Diagram

  8. Computer Control System • MATLAB based application • EIA-485 over Ethernet. • Outputs standard MIDI signal. • User level API for added functionality.

  9. Computer System Flowchart

  10. Demonstration • System emulating bass guitar. • 4 strings, 4 fingers. • Moderate tempo baseline. • System output to Yamaha MU100 tone generator.

  11. Testing • Verifying correctness of output. • Ensure negligible interference in sensors.

  12. Design Issues • Sensor orientation and positioning. • Testing different methods against needs. • MATLAB “real-time” MIDI output.

  13. Future Schedule

  14. Cost Analysis • Based on 10,000 Units over 5 years • 3 design engineers + other staff and overhead yields a total non-recost of 31.13. • Parts cost $103.60. • Overall cost per unit around $430. • Sell at $500. • Earn about 700,000 profit.

  15. Current Status • Important parts obtained. • Programming Microcontroller. • Constructing glove. • Designing MATLAB system.
