Facilitating Interconnectedness between Body and Space for Full-bodied Presence - Utilization of “Lazy Susan” video projection communication system -

A significance of a sense of togetherness or coexistence among remote communication partners has been pointed out in computer-mediated communication. In order to create such a co-existing situation, fullbodied presence of participants should be supported at each place. We devise two representation methods; representing self reflection in a shared video space, and projecting reflection of a remote partner onto the local tabletop. Then we construct “Lazy Susan” video projection communication system composed of a shared disk system and a video projection system based on this method. The results of experiments suggest our system can enhance an interconnectedness between self and a remote place, and between a remote partner and a local place, and simultaneously enhance a sense of coexistence. Based on this result we discuss and propose a novel approach focusing on duality of embodiment to facilitate interconnecting body with space for full-bodied presence.
