Kinect + Theremin = Therenect
The Therenect is a virtual Theremin for the Kinect controller. It defines two virtual antenna points, which allow controlling the pitch and volume of a simple oscillator. The distance to these points can be controlled by freely moving the hand in three dimensions or by reshaping the hand, which should allow gestures that are quite similar to playing an actual Theremin.
This musical instrument demo has been developed by Martin Kaltenbrunner at the Interface Culture Lab at the University of Art and Industrial Design in Linz, Austria. The software has been developed using the Open Frameworks and OpenKinect libraries.
Remarks: Talking to a professional thereminist revealed that there are still some significant improvements needed to simulate the exact behavior of an actual Theremin. This includes the scaling of the frequency control by the power of two and defining a smaller range for the amplitude control. We will soon post an updated version that also synthesizes the original Theremin sound.
