===Motion tracking HMD based on cameras===

Motion tracked-HMDs can be used for immersive remote viewing of dangerous situations, for use in military.<ref>Philco [[Headsight]], by two Philco Corporation engineers, Comeau and Bryan</ref> An immersive device like this does not need to have a computer rendering system attached. It can be attached to a motion tracked camera using an electromagnetic tracking system. This type of device can use a video screen for each eye. In this type of system, the head movements of the user are replicated by a remote camera, allowing him to look around the environment.<ref name=”1”></ref>
