Abstract

We present a set of interaction techniques for electronic musical performance using a tabletop tangible interface. Our system, the Audiopad, tracks the positions of objects on a tabletop surface and translates their motions into commands for a musical synthesizer. We developed and refi ned these interaction techniques through an iterative design process, in which new interaction techniques were periodically evaluated through performances and gallery installations. Based on our experience refi ning the design of this system, we conclude that tabletop interfaces intended for collaborative use should use interaction techniques designed to be legible to onlookers. We also conclude that these interfaces should allow users to spatially reconfi gure the objects in the interface in ways that are personally meaningful.
