The following are WWW-references on facial animation that might be useful for research on nonverbal communication. Facial animation is modeling human faces by the computer. Successful modeling always means having found objective information about the phenomenon modeled. So if a computer model shows certain cues in such a way that observers agree it is a cue then an objective description of this cue has been achieved. What I have seen on the site below is rather coarse, but it would be a start and can give guidance to a more NLP-oriented project.
