Studies have shown that interpreting facial expressions can significantly alter the interpretation of what is spoken as well as control the °ow of a conversation [28]. Im-proving the communication between humans and computers has been one of the driving forces in computer science over the years. This research has involved coordination between several fields of research including: psychology, biology, computer science, and engineer-ing. The key to creating a better communication between humans and machines involves developing more sophisticated techniques for interpreting
