Query: A Novel Face-tracking Mouth Controller and its Application to
  Interacting with Bioacoustic Models   We describe a simple, computationally light, real-time system for tracking
the lower face and extracting information about the shape of the open mouth
from a video sequence. The system allows unencumbered control of audio
synthesis modules by the action of the mouth. We report work in progress to use
the mouth controller to interact with a physical model of sound production by
the avian syrinx.
