ReverseCAVE: Providing Reverse Perspectives for Sharing VR Experience
Head mounted display (HMD) is rapidly spreading as a device for experiencing virtual reality (VR). However, VR with HMD is closed experience among those who are experiencing the VR, and can only be individually experienced by the specific person. We call this perspective gap. These perspective gaps exist in many situations. To address these problems, we present ReverseCAVE, a system for sharing the experiences of people in VR with others (observer). As another application, it is possible to visually recognize the actual appearance of the person performing the act at the motion capture studio and the superimposed character at the same time. ReverseCAVE has four translucent screens surrounding the player. VR environment that the player is experiencing is projected onto the screens. By this, the observer can see both the physical player and the VR environment experienced by the player simultaneously. Also, in the motion capture system, when viewing the actor from the observer outside of ReverseCAVE, the character is superimposed to the actor. This makes it look as if the actor is the actual character from the observer. We enhance the observers’ experience by ReverseCAVE.
