===1961 - First motion tracking HMD===

The true precursor of the HMDs available today was developed by two Philco Corporation engineers, Comeau and Bryan. It was called [[Headsight]] and it incorporated a video screen for each eye and a magnetic motion tracking system. This system was linked to a closed circuit camera. The device wasn’t developed for virtual reality applications. Instead, its goal was to allow immersive remote viewing of dangerous situations by the military. The head movements of the used would be replicated by a remote camera, allowing him to look around the environment. While the Headsight was a step in the evolution of the virtual reality headset, it lacked the integration of a computer and image generation.<ref name=”1”></ref>

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>
