Changes

HTC Vive Pre is the second Vive development kit. The headset has been introduced at CES 2016, and it adds a front-facing pass-through camera used for object and boundary recognition. It solves the problem of real space navigation while immersed in a virtual reality. Recognized objects are represented in user's field of view as glowing outlines and silhouettes. It is now entirely possible to change position from standing to sitting on a chair, walk from object to object in real world, and safely take advantage of all space that the room users play in provides. The system has two modes of operation. In the first mode, the Vive is inactive until users get close to a wall or an obstacle. The headset then shows a glimpse of the real world to give users enough time to react and avoid any obstacle. The second mode is activated by double-tapping a menu button on the controller. In this mode, users see an instant view of all their surrounding.  The only remaining problem and potential danger is the attached cord. Unfortunately, Chaperone does not detect the cord, and it is possible for users to trip over it and fall.
