Proceedings of the International Conference on New Interfaces for Musical Expression

We describe a simple, computationally light, real-time system for tracking the lower face and extracting informationabout the shape of the open mouth from a video sequence.The system allows unencumbered control of audio synthesismodules by action of the mouth. We report work in progressto use the mouth controller to interact with a physical modelof sound production by the avian syrinx.
