 Provide an all-in-one dataglove solution ◦ Emulate an “air guitar”  Marketable to a wide range of consumers, from children to HCI researchers  Motivation is to make the dataglove more accessible for both learning and fun  Create the entire package for $500

ObjectiveImplementation Use induction-based sensors25 turns, 36 gauge magnet wire Convert to digital signalsATMega644’s On chip A/D Converter Send digital signals to computerEIA-232 Convert digital input to MIDI output Pure Data

 14 Sensors made from 36 gauge magnet wire using 25 turns  Coils positioned on the three phalange of each finger, or two of the thumb

 Freeware version of MAX/MSP  Used in music technology industry  Graphical programming language  Ideal for manipulating data  Strong MIDI support

 Total of $95 in parts per AirBand Glove System ◦ Based on 10,000 units ◦ Approximately $40 per board ◦ $15 per pair of gloves  Factoring in labor and overhead $425 total cost per unit  Sell at $500  Earn $750,000 profit

 Finished ◦ Completed glove ◦ Gotten successful readings from sensors ◦ Observed clear thresholds

 Finished ◦ A/D Worked ◦ Implemented thresholds ◦ PCB laid out and ordered ◦ All parts ordered  Working on ◦ Soldering ◦ Finalizing PIC code ◦ Connecting to gloves ◦ Connecting boards together

 Finished ◦ Emulated hands ◦ Tested with virtual serial port ◦ Read hands and recognize notes ◦ Output sound  Working on ◦ Implementing the final control scheme ◦ Looking into possible modularity

 Present demo at Under the Couch  Verify glove has correct mappings  Demonstrate playability in real time

 Wireless Implementation  Battery Powered  Accelerometer to read hand orientation  Distance sensing

 Demo by April 30 th  Report by April 30 th
