One leading content creator described VR as “hacking your brain” to make you believe you are someplace that you are not. The illusion of being in that place, known as “presence,” can be all the more convincing when the virtual world responds to your eye or hand movements or commands from a game controller.
Virtual reality is hardly a new technology. It’s been with us since 1985, when former Atari programmer Jaron Lanier experimented with some of the first VR headsets. There have been several failed attempts to commercialize VR, most famously Nintendo’s Virtual Boy in 1994, which is best known for making people feel motion sickness after playing Mario Tennis for a few minutes.
