TactoSonix is a multitouch environment for musical expression. It consists of a hardware interface that was designed and built by the author and an Industrial Design consultant, as well as software that is being developed as part of the author's M.A. thesis research.
The TactoSonix hardware stands out from most other multitouch devices in that it supports two methods of implementing multitouch technology: Frustrated Total Internal Reflection and Rear Diffused Illumination. As such, it is an excellent platform for prototyping ideas about tangible objects, and also offers a more robust finger tracking method in its FTIR configuration.
The following screenshots show the TactoSonix software in the environment based on the metaphor MAKING MUSIC IS COOKING.
