I built a patch that uses computer-vision to control sound-plaback with head-gestures.
Here is the patch and a video that explains how to use it and what you can do with it.

The patch was developed in the process of building an interactive installation experimenting with the extension of language in the combination of sound and language.
I realized the Prototype - compo - which provides an instrument to create future interactive compositions between words and music.
It is documented over here: https://wwws.uni-weimar.de/kunst-und-gestaltung/wiki/GMU:Artists_Lab_IV/Leon_Goltermann
