VR HOW DOES IT WORK? The popular VR headsets recently released such as the Oculus, HTC etc. Usually require three things to function. A PC, console or smartphone to run the app or game, a headset which secures a display in front of your eyes (which could also be the phone's display) and some form of input – such as head tracking, controls, hand tracking, on device buttons or voice. Headsets such as Oculus and PlayStation VR, are often referred to as HMD which means is that they are head mounted displays.

EARLY IDEAS INTO VIRTUAL REALITY Some of the earliest ideas regarding around VR came from a book in the 1930s by science fiction writer Stanley G. Weinbaum. The idea of a pair of goggles that let the wearer experience a fictional world through holograms, smell, taste and touch.
EARLY IDEAS INTO VIRTUAL REALITY In the mid 1950s cinematographer Morton Heilig developed the Sensorama which was a arcade-style theatre cabinet that would stimulate all the senses, not just sight and sound. Featuring various components such as smell generators and a vibrating chair. The Sensorama was intended to fully immerse the individual in the film. He also created six short films for his invention all of which he shot, produced and edited himself.
FIRST VR / AR HEADSET In 1969 The Sword of Damocles was the first VR head mounted display that was connected to a computer and not a camera. It was too heavy for any user to comfortably wear and was suspended from the ceiling. The user needed to also be strapped into the device. The computer generated graphics were very primitive wireframe rooms and objects.
