MirrorFugue: Communicating Hand Gesture in Remote Piano Collaboration

Xiao Xiao, Hiroshi Ishii


Playing a musical instrument involves a complex set of continuous gestures, both to play the notes and to convey expression. To learn an instrument, a student must learn not only the music itself but also how to perform these bodily gestures. We present MirrorFugue, a set of three interfaces on a piano keyboard designed to visualize hand gesture of a remote collaborator. Based their spatial configurations, we call our interfaces Shadow, Reflection, and Organ. We describe the configurations and detail studies of our designs on synchronous, remote collaboration, focusing specifically on remote lessons for beginners. Based on our evaluations, we conclude that displaying the to-scale hand gestures of a teacher at the locus of interaction can improve remote piano learning for novices.
