Coexistent Space: Collaborative Interaction in Shared 3D Space

Abstract

It has long been a desire of human beings to coexist in the same space together with people in remote locations, and interact with them in a natural way. There have been proposed various concepts to connect the real world with the remote world in 3D space [1, 2]. In this paper, the concept of Coexistent Space for collaborative interaction in shared 3D virtual space is proposed. Coexistent Space provides not only the feeling of coexistence as the sense of being with others, but also a shared virtual workspace for collaboration. The main feature is that the users can share a virtual whiteboard for writing interaction and manipulate shared virtual objects with the bare hand touch interaction.
