Zwischen 1993 und 1994 entwickelte Arthur Clay am STEIM (Studio for Electro-Instrumental Music, Amsterdam) mehrere experimentelle, handgesteuerte Controller-Instrumente. Dazu zählen Air-Bow, ein virtuelles Streichinstrument, sowie Spaceball, ein intermedialer Controller zur simultanen Steuerung von Klang und Bild in Live-Elektronik- und Video-Performances. Diese Arbeiten stehen im Kontext der STEIM-Forschung zu gestischen Interfaces und neuen musikalischen Instrumenten.
Air-Bow
A virtual string instrument developed at STEIM (Amsterdam, 1993–94).
Air-Bow is a gestural performance interface that simulates the action of bowing a string instrument without physical strings. Through spatial hand movement and sensor-based control, the performer shapes sound in real time, translating bow-like gestures into electronic musical expression and enabling highly expressive, continuous modulation of tone and dynamics.
Spaceball
An intermedia performance controller developed at STEIM (Amsterdam, 1993–94).
Spaceball is a hand-operated spherical interface designed to control sound and image simultaneously in live electronic performance. By manipulating the ball’s position, rotation, and pressure, the performer dynamically shapes audiovisual parameters, creating a unified gestural link between physical movement, electronic sound, and live video.
