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

The patch was developed in the process of building an interactive installation. 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
