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. Positional tracking is an essential technology for XR, making it possible to track movement with six degrees of freedom (6DOF). Some XR headsets require a user to stay in one place or to move using a controller, but headsets with positional tracking allow a user to move in virtual space by moving around in real space.
