What is virtual reality (VR)?

Have you ever lost yourself in a book or a movie? That’s a kind of virtual reality.

It is an experience of the world that doesn’t really exist.

From that simple definition, the idea doesn’t sound especially new or exciting until you are looking at an amazing view of Earth while standing in space, for example, or flying a kite and hearing the birds chirping and waves lapping onto the beach—so that’s a kind of virtual reality.
