This is my Master's Thesis for Helsinki University of Technology, Laboratory of Acoustics and Audio Signal Processing, Finland.

The title is Real-time Implementation of the Virtual Air Slide Guitar.

The synthesis was made with Pure Data and a Naturalpoint TrackIR 3:PRO infra red camera with a modified Optitrack SDK was used for tracking and gesture recognition.
