Shared Virtual Space Communication System with Pseudo Awareness of Presence and Gaze

Abstract

A shared virtual space communication system was developed, with multi-user walk-through function using locomotion interface, and voice communication function by Voice over IP technology. An algorithm for the automatic control of the group of the voice communication was implemented using spatial relationship of the users. Visual and auditory awareness about the presence of the other users in the conversational area were also attained. The automatic group control and awareness representation were effective for natural and smooth voice communication in shared virtual space. A pseudo gaze awareness system using each user's voice volume has also been developed.It was experimentally demonstrated that the pseudo gaze awareness is effective to enhance the conversation.
