Abstract

In this paper, we propose a model for estimating conversational activity based on the analysis of enhanced embodied interaction, and develop a virtual audience system. The proposed model is applied to a speech-driven embodied entrainment wall picture, which is a part of the virtual audience system, for promoting enhanced embodied interaction. This system generates activated movements based on the estimated value of conversational activity in enhanced interaction and provides a communication environment wherein embodied interaction is promoted by the virtual audience. The effectiveness of the system was demonstrated by means of sensory evaluations and behavioral analysis of 20 pairs of subjects involved in avatar-mediated communication.
