Abstract

This paper reports on the process of developing a virtual-acoustic proto-instrument, Vodhran, based on a physical model of a plate, within a musical performance-driven ecosysytemic environment. Performers explore the plate model via tactile interaction through a Sensel Morph interface, chosen to allow damping and localised striking consistent with playing hand percussion. Through an iteration of prototypes, we have designed a standalone proto-instrument that allows a bodily interaction between the performer and the virtual-acoustic plate in a way that redirects from the perception of the Sensel as
a touchpad and reframes it as a percussive surface. Due to the computational effort required to run such a rich physical model and the necessity to provide a natural interaction, the audio processing is implemented on a high powered single board computer embedded within the object itself. We describe the design challenges and technological solutions we found during the implementation of the Vodhran.
