        Abstract
    
        This paper describes a real-time system for finding and tracking a human
        face and mouth, and recognizing mouth shapes that correlate with internal states
        such as happiness or sadness. It has been tested on hundreds of users and
        demonstrated extremely reliable and accurate performance.
