'''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 also known as '''6DOF tracking''', for the 6 degrees of freedom (DOF), which are ways that an object can move: horizontally, vertically, depthwise, and three rotation movements: pitch, roll, and yaw.

It can be done using a number of different hardware technologies, such as [[electromagnetic tracking]] or [[camera-based tracking]]. Methods of camera-based tracking include methods using [[SLAM]] or [[VIO]]. PnO tracking is related to rotation tracking, which uses [[3DOF]] of space.
