==Purpose==

The purpose of the Chaperone system is to warn the user when they approach a physical barrier, to which they are blind because of the headset they are wearing. This will ideally prevent collisions and minimize accidents, and thus solve the problem of real space navigation in virtual reality. The system recognizes objects and represents them in the user's field of view as glowing outlines and silhouettes. It makes it entirely possible to change position from standing to sitting on a chair, walk from object to object in real world, and safely takes advantage of all available space in a user’s room.

A secondary purpose for the Chaperone system is to allow games to interact with the user in a unique way. Because the Chaperone system has information about the user's environment, virtual applications can react to the user's surroundings. It could, for example, generate a location that matches the orientation and layout of the user's room. Conversely, the system could use techniques like overlapping spaces or [[directed walking]]<ref>Suma, E.A., Lipps, Z., Finkelstein, S., Krum, D.M. and Bolas, M. (2012).
