InterChat: A Typing-Driven Embodied Entrainment Character Chat System

Abstract

InterActor is a speech-driven CG-embodied interaction character driven by InterRobot technology (iRT). This technology generates communicative motions and actions on the basis of only speech input for entrained interaction and communication. In this study, we apply iRT to characters in an online chat for expanding the input interface from a voice input to a typing input, and develop a typing-driven embodied entrainment character chat system, InterChat. InterChat generates a character's communicative motions and actions from the user's typing rhythms with an enhanced iRT and the corresponding actions from the meaning of messages in transmission and reception. The effectiveness of this system is demonstrated by conducting a sensory evaluation experiment during a chat communication.
