DefinitionVR (Virtual Reality) is technology that makes you feel as if you have entered a virtual space created by a computer.
ExplanationA head-mounted display or similar device covers the eyes so that only the virtual scene fills your view, and the image changes as your head and body move, creating a sense of immersion. Since the real surroundings are no longer visible, VR can be described as replacing reality with a virtual space. Typical uses include walking through a building before it is built and safely rehearsing dangerous work.
AnalogyIt is like stepping into a windowless room whose walls and ceiling are covered with projections of another world that turns with you whenever you look around.
Memory hook"Virtual" describes something that works as the real thing in effect, even though it is not. The name points to a reality that is not real but can be experienced as if it were.
