Force-Sensing Chair for Augmented Instruments

Abstract The device was implemented as part of the greater GuitarAMI ecosystem for augmented instruments. Though the word ”guitar” is a prominent part of the name, we consider a force-sensing device to be an asset for any performer and as such discuss three possible builds for this device: two for seated musicians and a third for a standing musician. These three prototypes were constructed using high-load force-sensitive resistors and evaluated using simple effects mapped to their output values. These preliminary use-cases show that these three module builds are promising proof of concept for future development and deployment as musical interfaces.

This system was implemented by two people as part of a course project, Gestural Control of Sound Synthesis, from McGill University. The author was in charge of developing the software and testing.
