Tracking volume

Tracking volume is a term used to describe the size of the area within which the tracking camera is still able to capture user’s physical movements. Usually, the tracking volume is determined by camera’s horizontal and vertical field of view.

For practical reasons, most virtual reality experiences have been limited to just sitting. Most users simply do not have an area large enough to take advantage of all possibilities that large-scale tracking offers. Despite this fact, Oculus has successfully demonstrated a room-sized tracking volume experience at E3 2015. By using two cameras mounted on a wall a few feet away from each other, the company has managed to cover an area of approximately 12x12 feet. The tracking space extended from wall to wall and from floor to ceiling.
