We report on an experiment designed to evaluate sensorimo- tor adaptation in a motion-based sound synthesis system. We propose to investigate a sound-oriented task, namely to reproduce a targeted sound. The system is a small handheld object whose motion drives a sound syn- thesizer. In particular, the angular velocity is captured in real-time by a gyroscope and transmitted wirelessly to the sound engine. The targeted sound is obtained when the motion matches a given reference velocity profile. If the velocity profile is performed with sufficient accuracy, a specific sound is heard, while a incorrect velocity profile produces either noisier sound or sound with a louder high harmonic (depending on lower or higher velocity values). The results show that subjects are generally able to learn to reproduce the target sound. Motor adaptation is also found to occur, at various degrees, in most subjects when the profile is altered.
