Research on autonomous interaction of virtual avatar during its master´s operation silence period

The paper proposes an adaptive time window based algorithm to decide if a user falls into operation silence period or not during the process of a constructed remote virtual interaction. The time window is selected considering history operation data of the user in current interaction. Operation silence is explained as that the user loses interest to interaction topic. The interest loss results to sleepy. Sleepy state is expressed through avatar´s body movement in virtual environment. A remote virtual interaction system is developed to demonstrate the proposed algorithm and design of avatar´s autonomous interaction. The autonomous interaction of the avatar whose master falls into operation silence period is expected to improve the naturalness of the virtual interaction environment.
