In this paper, we present personality as a means ofcontmlling non-verbal behaviors. It consisls of two dimensions, dominance VS. submissiveness and friendliness VS. hostility, based an the Interpersonal Theory in psychology. The upper-tono humanoid SlC equipped with real-time audio-visual multiple-talker tracking system is used as a testbed for social interaciion.
