Abstract:
We have developed a speech-driven embodied group entrained communication system called “SAKURA” for enabling group interaction and communication. In this system, speech-driven computer-generated (CG) characters called InterActors with functions of both speakers and listeners are entrained as a teacher and some students in a virtual classroom by generating communicative actions and movements. In this study, for enhancing group interaction and communication, we analyze the eyeball movements of a lecturer communicating in a virtual group by using an embodied communication system with a line-of-sight measurement device. On the basis of the analysis results, we propose an eyeball movement model that consists of a saccade model and a model of the lecturer’s gaze at the audience, called “group gaze model.” The saccade model reveals eyeball movement with a delay of 0.20 s with respect to the lecturer’s head movement. A group gaze model reveals the rate of the lecturer’s gaze (Center: 60%, Left-side: 27%, Right-side: 13%). Then, we develop an advanced communication system in which the proposed model is used with SAKURA. Using this system, we perform experiments and carry out sensory evaluation for determining the effects of the proposed model. The results reveal that the proposed model is effective for group interaction and communication in the speech-driven embodied group entrainment characters system.
