Virtual reality

Virtual reality (VR) is the computer generated simulation that allows human to engage with an artificial world. A sophisticated blend of software and hardware made virtual reality possible.

VR technology uses multi-projected environments or VR headsets with a small screen in front of the eyes to generate realistic sounds, sights, and other experiences that simulate a user's actual presence in the virtual world.

Augmented reality (AR) and mixed reality, sometimes known as extended reality (XR) are two further types of VR-style technologies.
