Voice performance with infrared sensors on shirt. This is an instrument which is a shirt installed 10 infrared distance sensors. They are connected to computer, change voice following performer's body movements.

On right hand, there are 4 buttons and 2 dimensional tilt sensor. Computer analyzes voice sound and the position of the right hand, it changes many parameters of modulation patch in real time.

ADACHI's composition "Yumiko"(1997) performed by students of Department of Moving Images and Performing Arts, Tama Art University in Jan. 2008. A choir without precise pitch. Nonsense words.

Improvisation with some self-made electronic instruments built in tupperwares includes Tomomin, Tomomin Synthesizer. Live recording at Uplink Factory on 8/4/2006

Performance with self-made electronic instrument. Metal chopsticks works as registance and conductor. All sounds are generated by 1 C-MOS IC 40106. Live recording at Out-Lounge on 5/11/2006

A performance with a self-made wearable electronic sound system includes sound generator, speaker, amplifier and sampler with batteries. All sounds are triggered by many tilt sensors and 2 light sensors on performer's body, these sensors capture movements of performer. In addition, voice and a bicycle bell were used in the performance. Basic concepts are interaction between body and sound, and intervention between sound and environment. A recording from the public space performance tour titled "Art of Begegnung II" in Germany in July 2007.

Demonstration of self-made sound generator with 2 of C-MOS IC 40106. With external wires for touch. Originally it is stereo sound.

Kinetic video installation consists of the suspended three dusters with video cameras, electric motors and propellers. They spin and fly in unpredictable way, sometimes in unison. Audience sees their dance and the vision from them through three video monitors on the floor. The generated video image is a modulated environment that audiences exist.

Kinetic video/sound installation; two snail robots follow 2 same black line drawings on the floor. One snail has a wireless microphone. Another has a wireless camera. The radio on the side of a drawing receives the signal from microphone and also the TV monitor receives the signal from camera. As a result, radio makes a feedback sound melody follows the natural overtone and TV generates abstract video image. Sound and image are equivalent for the drawing. And 1 pig behaves sarcastically on the wall.
