'''Positional tracking''' is a technology that allows a device to know its position relative to the environment around it. It uses a combination of hardware and software to achieve the detection of its absolute position. It is an essential technology for [[virtual reality]] (VR), making it possible to track movement with six [[degrees of freedom]] (6DOF) <ref name=”1”> StereoLabs. Positional Tracking.

Positional tracking is not the same as 3DOF head tracking. 3DOF head tracking only registers the rotation of the head ([[Rotational tracking]]), with movements such as pitch, yaw, and roll. Positional tracking registers the exact position and orientation of the headset in space, recognizing forward/backward, up/down and left/right movement <ref name=”3”> Rohr, F. (2015).
