Such dis- tinction is critical to enabling different perceptions; Real-time three-dimensional (3D) interactive displays however, the optics designs associated to each eye refer to display devices servo to the line of sight of a across these configurations have much commonality. user, allowing not only free head motion, but also The first graphics-driven HMD was pioneered by potentially and importantly full body mobility. Ideally, Ivan Sutherland in the 1960s.[1] The acronym HMD one could wish for such capability to exist without the has been used since to also refer to within military need to wear any view-aided device. However, unless a applications to helmet-mounted displays, where the display system could be created in space, anywhere and display is attached to a military helmet.[2,3] The U.S. anytime, a simple solution is to wear the display. Such Army flew a hemlet-mounted sighting system on the displays are today rather referred to as head-worn Cobra helicopter, and the Navy shot missiles using displays, but historically they have been referred to HMDs in the 1960s. The Integrated Helmet And as head-mounted displays (HMDs). Because humans Display Sighting System (IHADSS) was then deployed have not evolved to wear heavy devices, the challenge
