What is the background of Virtual Reality?
VR was invented in the 1950s, about 60 years ago. The term VR, which is widely used in the modern era, began to be popularized by Jaron Lanier in the 1980s. The first virtual reality was created when computer scientists Ivan Sutherland and disciples Bob Sproull first invented a virtual reality display system called The Sword of Damocles (GlobalData Technology, 2020). Virtual reality includes both hardware and software. It has become more wide-spread and has been used more and more for training or simulation in NASA and the U.S. military. Since then, in the 2010s, when technology began to develop at a faster pace, a system to connect to computers was created, and VR devices such as games and headsets that we are familiar with now were created.
