VR is possible using electronics and computer technology. More primitive ideas can be implemented using more primitive technology, such as a fixed [[stereoscope]], or panoramic murals (or 360-degree murals). These fill the viewer’s field of vision with the intention of making them feel a sense of presence at a certain historical event or scene.<ref name=”1”> Virtual Reality Society.

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>
