Coexistent Space: Collaborative Interaction in Shared 3D Space

It has long been a desire of human beings to coexist in a same space together with people in remote locations, communicate and interact with them in a natural way. There have been various proposed concepts to connect the real world with the remote world in 3D space [1, 2]. In the paper, the concept of Coexistent Space is proposed for collaborative interaction in shared 3D virtual space. Coexistent Space provides not only the feeling of coexistence as the sense of being with others, but also a shared virtual workspace for collaboration. Its 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.
