"The birth of VR has begun in the 1950s and 1960s with the device named “the ultimate display”. The AR and VR have reached their current states as a result of the interest in VR and the rapid advances in technology. Given some of the studies contributing to this development, the chronological ranking is seen as follows. The first idea of an HMD was patented by Thelma McCollum in 1943. Morton’s Telesphere Mask was designed to provide stereoscopic television and sound, and it was patented in 1960. In 1962, Sensorama machine was built by Heiling after years of work. This machine was an arcade-style cabinet with a 3D display with a wide field of view, sound, vibrating seat, and scent producer. Comeau and James Bryan developed the Headsight in 1961 which was actually the first fabricated HMD. In 1968, Ivan Sutherland developed the first HMD system called “Sword of Damocles”, which displayed output from a computer program in a 3D stereoscopic display."
