'''PnO''' means position and orientation. It comes from the phrase "P and O".
+'''Position and orientation''' (P&O) is a quantity that holds [[position]] and [[orientation]]. It is often called PnO.
−It it used in [[6DOF tracking]]. It is used in [[magnetic tracking]] systems, such as systems from [[Polhemus]].
+It it used in [[PnO tracking]]. It is used in [[magnetic tracking]] systems, such as systems from [[Polhemus]].
−PnO is substantially the same concept as [[pose]]. It is the rotation and translation of an object relative to a root transform. In terms of a [[transform matrix]] with [[SRT]] order, it is just the rotation (R) and translation (T).
