Abstract
A lecturer and audiences share embodied rhythms in presentation. By focusing on entrainment in face-to-face communication, the authors have already developed the speech-driven embodied CG character InterActor with both functions of speaker and listener. In this paper, an embodied presentation system with speech-driven InterActor characters and nodding objects pointed by a lecture is developed. A lecturer can specify texts, logotypes, symbols, graphs in any slides made by PowerPoint as nodding objects and can arrange characters to an arbitrary place of the slide. The effectiveness of this system for presentation support is demonstrated by a sensory evaluation experiment conducted in an actual presentation scenario.
