Playing on Heart-Strings: Experiences with the 2Hearts System

Mccaig, Graeme and Fels, Sidney S.

Proceedings of the International Conference on New Interfaces for Musical Expression

Here we present 2Hearts, a music system controlled bythe heartbeats of two people. As the players speak and touch, 2Hearts extracts meaningful variables from their heartbeat signals. These variables are mapped to musical parameters, conveying the changing patterns of tension and relaxation in the players’ relationship. We describe the motivation for creating 2Hearts, observations from the prototypes that have been built, and principles learnt in the ongoing development process.
