Unlike the two previous demos, however, it monitors the user’s head movements in real space, and it’s able to translate those movements into not just orientation changes — looking up, down, or behind you — but also as actual motion, which previously was possible only by using a game controller in conjunction with the Rift. It utilizes an “outside-in” system: an externally mounted camera tracks small LED lights on the prototype’s faceplate, adding three “degrees of freedom” (forward/backward, left/right, and up/down) to the Rift’s tracking ability. Up until now, developers and early Oculus adopters have only been able to accomplish this by taping a Razer Hydra motion controller to the side of their Rift headsets.
