'''Augmented reality''' is a technology of putting computerized objects in the physical world visually. Augmented reality can be done using an AR headset. If using a headset, the headset requires [[PnO tracking]]. Augmented reality can involve fiducial markers for tracking, such as [[ArUco marker]]s.

To register the coordinate system to the environment, [[6DOF tracking]] must be used. Tracking can be done optically (using fiducial markers or markerless SLAM), or by using [[magnetic tracking]] or [[lighthouse tracking]].

Augmented reality can be see-through or passthrough. See-through uses an [[optical see through display]] like on the [[Magic Leap]]. Passthrough uses a camera feed and an optically opaque display, like on a [[Meta Quest Pro]].
