Virtual reality (VR) is a computer-generated environment that stimulates the human senses and creates an illusion of visual perception. VR can be referred to as immersive, because it takes users to another place or time.

Examples of virtual reality include the movie theater experience, theme parks, and video games. The term virtual environment refers to a computer-generated simulated world that can be used through an avatar (a digital representation of the user).

The Oculus Rift was the first commercial headset designed for consumers to use in high-end entertainment centers. It was released in 2016, and was created by Oculus VR — a company founded by Palmer Luckey with the aim of making VR mainstream for consumers.

Prior to its release, the Rift required a high-end gaming computer to function. The Rift used the Oculus Touch controllers, which are designed to work like an extension of your hand in the virtual environment. The other major competitor is HTC VIVE , which was released in 2016. 

HTC VIVE uses two motion-sensing handheld controllers that allow users to reach out and touch objects in the virtual environment—similar to how they may interact with real objects in the real world.
