“Virtual reality” (VR) is easily confused with "Augmented Reality". But, whereas Augmented Reality adds virtual aspects to the real world, Virtual Reality, often abbreviated to VR, is a completely computer-generated reality. The idea was first mooted as long ago as the 1950s, but only with the development over the past few years of high-performance VR goggles and 360-degree cameras has it become possible to make advances in Virtual Reality. The technology can be used in many areas, such as the prominent example of pilot training in a flight simulator and applications in industry for the development of prototypes. It also forms the basis of many games, movies and apps.
