Positional tracking tracks the absolute position of the [[HMD]], hands and other devices and body parts within the 3 dimensional space. Positional tracking records the [[translational movement]]s, left/right, forward/backward and up/down, of your device. Precise and low [[latency]] positional tracking is essential to have a good [[VR]] experience and produce [[presence]].

By contrast, [[rotational tracking]], records the [[rotational movement]]s of your HMD, such as turning and tiling of your head.
