Augmented reality using headsets benefits from a high field of view and a high focal depth range. Focal depth range can be done using [[light field display]]s or [[holographic display]]s.

'''Augmented reality''' is when there are virtual objects in the real world. Augmented reality can be done using an AR headset. If using a headset, the headset requires 3D 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]].

===Environment tracking===
Environment tracking is the capability of a gadget to know its position and orientation relative to its environment. This is required so that the virtual imagery has correct [[registration]] to the real world.

The historical development of AR technologies intersects with that of virtual reality.
