Changes

The Head head [[tracking]] in the Rift has no visible [[latency]]. The [[Tracking#Systems|tracking system]] employed by Oculus Rift is called [[Constellation]]. It is an improved version from [[DK2]] and [[Crescent Bay]]. While [[rotational tracking]] is achieved with [[inertial measuring unit|inertial measuring units]] (IMUs), [[positional tracking]] is accomplished with an [[Oculus Sensor]] ([[outside-in tracking]]). Tiny LED markers are placed on the HMD, and the camera sensor is able to recognize these markers to track the position of the HMD. The markers on the back straps of the HMD allows the back of the user’s head to be tracked. This potentially allows for 360 degrees of tracking. The Rift's tracking is designed for both [[Seated VR|seated]] and [[standing VR]] experiences.
