When we are face to face with others, we use not only speech, but also a multitude of nonverbal be- haviors to communicate with each other. A head nod expresses accordance with what someone else said before. A facial expression like a frown indicates doubts or misgivings about what one is hearing or see- ing. A pointing gesture is used to refer to something. More complex movements or configurations of the hands depict the shape or size of an object. Of all these nonverbal behaviors, gestures, the spontaneous and meaningful hand motions that accompany speech, stand out as they are very closely linked to the semantic content of the speech they accompany, in both form and timing. Speech and gesture together comprise an utterance and externalize thought; they are believed to emerge from the same underlying cognitive representation and to be governed, at least in part, by the same cognitive processes (Kendon, 2004; McNeill, 2005). Despite this important role of co-speech gestures in communication, little is known, however, about the mechanisms that underlie gesture production in human speakers (cf. Bavelas et al. (2008), de Ruiter (2007)) as well as the functions gesture use fulfills in communication and even beyond, e.g. in educational or therapeutic contexts. My talk at the symposium showed how building computational simulation models of natural, communicative behavior and employing these models in virtual humans allows to address these research issues.
