Stereopsis
Sir Charles Wheatstone introduced the concept of stereopsis to the world. He recognized that each eye shows the different visual from horizontal position, image produced by each eye differs from the other. This invention changed the viewing concept. Human brain combines two different photographs if an object is captured from different position. This process is known as retinal disparity. An illusion of depth has been created from flat picture that can only be differentiated horizontally -

Link Trainer
Link Trainer is also known as “Blue Box” This invention is the world’s first commercially build flight simulator created by Edwin Albert Link at Link Aviation Devices, Inc. This technology is used to train more than 500,000 US pilots along with the other nation pilots from Germany, Canada, and Australia etc. The motor of the device is connected to rubber and steering column. This gave pilot accurate readings, exact replica of turbulence and interference during the flight takeoff and landings. -
Pygmalion’s Spectacles
1935 is the year when Stanley G. Weinbaum (American Science Fiction Writer) gave the idea of Pygmalion’s goggles. According to him, these goggles can provide a unique experience to the users where they can experience the world through holographic view along with different smells, touch and taste. -
Telesphere Mask
Yet another invention of Morton Heilig, cames to the existence in year 1960 when he introduced Telesphere mask. This mask (headset) provided a wide vision of picture with stereoscopic 3D with ear buds for stereo sound but without motion tracking. This was the first example of Head Mounted Display. -
Sensorama
In 1962, Cinematographer Morton Heilig invented “Sensorama” a mechanical device. As a cinematographer he created six short movies which run on arcade styled theater. It’s something like a large booth machine. In these theaters users can experience all senses, not just sound and sights. It is a combination of 3D screen, stereo speakers, smells, vibrations under the seats and atmospheric effects like wind. Heilig considered Sensorama to be the “future of cinema”. -
Ultimate Display
Year 1965 came with the concept of ultimate display where users could experience computer controlled virtual world. This concept is so accurate that at some extent very few users can explain the difference between virtual and the actual world. First time users of emerging VR can interact with the objects because of Head Mounted Display (HMD). -
Air Force Flight Simulator
Thomas Furness a professional military engineer, launched flight simulator dedicated to Air Force. Some people still agree that after the launch “world has seen an immense growth in the field of VR”. But this became possible only because there were dedicated funds for the flight simulator. -
Sword of Damocles
Considered as the first virtual reality head mounted system, this was the very first time when the mechanism was connected to the computer, not the camera. Ivan Sutherland and his student Bob Sproull were the creators.”. This Machine use to be big and scary many of the components are fitted to roof of the lab. Because of its size, machine was not developed out of lab. This System was designed in a way if user move its head then they can see the virtual wire frame shape. -
Video Place
Krueger’s next project was video place. The machinery was designed by computer graphics, projectors, position sensing technology and video cameras. First public appearance was at Milwaukee Art Center, Wisconsin.Here the user has to stand at specific place in a dark room where his movements would be captured by video cameras and after processing by computer system projectors shown it on silhouette.
