Virtual reality, also referred to as VR is a technology that
uses a headset to generate images and sounds and other cues that help to make
the user believe they are in an imaginary environment.
A person using a virtual reality headset is able to move
their head and see the artificial world as if it was real. Virtual reality
worlds can be created to seem real or science fiction.
The term virtual reality was first used in a book published
in 1938, and then in 1982 in a science fiction book.
Virtual reality began in the 1960s when a head mounted
display was created but it took many years before the consumer market began to
be truly interested in it. It wasn't until the 2010s that a virtual reality
device truly peaked consumer interest.
