The term virtual reality (VR) was coined by Jaron Lanier in the mid-1980s. VR, or virtual reality, is a computer-simulated environment in which users can interact with digital objects either by using a headset that blanks out everything around them or by using a tracked device like a magic wand. It is a technology that allows people to immerse themselves in an alternate reality by giving them the illusion that they are physically in another place or time. Head-mounted displays allow users to see the real world in front of them and also interact with digital objects that appear in the space in front of them. Using head-mounted motion controls, users can move and interact with these objects.
Although virtual reality has many applications, it is currently being used primarily in the gaming industry, where it can provide an interactive, immersive experience that is more fun than traditional video games. Virtual reality is quickly making inroads into the commercial world, where it is being used for entertainment, business, education and healthcare.
One of the most promising VR devices is Google Cardboard, which uses a smartphone to project a VR experience onto a piece of cardboard that users can view through the phone. With Cardboard, users can view websites, play games, and even video chat with family members.
