Oroboro: Collaborative Music Controller with Interpersonal Haptic Feedback
OROBORO is a novel collaborative controller which focuses on musical performance as social experience by exploring synchronized actions of two musicians operating a single instrument. Each performer uses two paddle mechanisms – one for hand orientation sensing and one for servo-motor actuated feedback. We introduce a haptic mirror in which the movement of one performer’s sensed hand is used to induce movement of the partner’s actuated hand and vice versa.
