Jo Kazuhiro / Inaudible Computing (audio input hardware for sensor data acquiition on mobile devices) http://jo.swo.jp/

Inaudible computing, an extension of physical computing.

Demo 1: push button
Mona lisa “shadow of sound”. The installation takes a picture of the person when the button is pushed and then generates the sound of the image.

Demo 2: fader controller
The SINE WAVE ORCHESTRA stay amplified. Each participant choose a sine wave frequency,

Demo 3: voltage amplitude circuit
Using USB for power.
The instrument of aeo, accelerometer, microphone, distance sensor and light bulb.

Demo 4: voltage - frequency circuit.
Using i LDR light sensor to change the frequency. Connects to iPhone. Calls it. The iphone is a device for wireless communication sensor.

Future work:
mobile phone as Dat transmitter.
voice recorder as data recorder
voice recognition as audio processing

The projects are posted to instructables so we can all have a go at making them too.
