Positional tracking is a technology that allows a device to estimate 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 VR technology brings various benefits to the VR experience. It can change the viewpoint of the user to reflect different actions like jumping, ducking, or leaning forward; allow for an exact representation of the user’s hands and other objects in the virtual environment; increase the connection between the physical and virtual world by, for example, using hand position to move virtual objects by touch; and detect gestures by analyzing position over time <ref name=”2”></ref> <ref name=”4”> Boger, Y.
