ReverseCAVE experience: providing reverse perspectives for sharing VR experience

Abstract

VR games are currently becoming part of the public-space entertainment (e.g., VR amusement parks). Therefore, VR games should be attractive for not only players but also observers. However, VR with HMD is a closed experience among those who are wearing HMD, 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 (observers). 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. The VR environment 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.
