The Lorentz Lap Brass: Method for Frugal Integrated Sonic/Haptic Interaction

Adam G Schmidt, and Michael Gurevich

Proceedings of the International Conference on New Interfaces for Musical Expression

Abstract:

This paper presents an affordable and accessible method for integrated sonic/haptic interaction via a low-cost setup utilizing Lorentz Force Actuation – a form of electromagnetic actuation – and exemplified by the The Lorentz Lap Brass, a new electromagnetically-actuated musical instrument and interface (EMAII). This style of actuation is uncommon in NIMEs, though it presents rich opportunity for cost-effective tactile feedback, infinite sustain, and feedback control. In an effort to encourage open-source knowledge sharing, replication, and adoption of this novel technique, we describe the underlying concepts, designs, and techniques for this method and distribute schematics, CAD, and code used in the setup. Results of a preliminary user study are discussed and offer perspectives and avenues for improving, extending, or iterating on the current system.
