−'''Position and orientation tracking''' ('''PnO tracking''') is 3D tracking of an object's [[position and orientation]] in space. It can be used to track display headsets and handheld input devices.
+'''Position and orientation tracking''' ('''PnO tracking''') is tracking of an object's [[position and orientation]] (PnO) in space. It can be used to track display headsets and handheld input devices.
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]].
