'''Position and orientation tracking''' ('''P and O tracking''') is 3D tracking of an object or device's [[position and orientation]] in 3D space. It can be used to track a headset or controller. It is used in devices like the [[Meta Quest 2]]. It is also known as '''6DOF tracking''', for the 6 degrees of freedom (DOF): horizontal, vertical, depthwise, pitch, roll, and yaw. It is used in an [[absolute positioning system]]. It can be done using a number of different hardware technologies, such as [[electromagnetic tracking]] or [[camera-based tracking]].
