What is Virtual Reality?
Virtual reality is a computer generated environment, often portrayed in movies such as the Lawnmower Man and the Matrix.

What is Augmented Reality?
In virtual reality we put you in a virtual environment. In augmented reality, we bring virtual objects into the real world – look there is a virtual object sitting on my desk.

Why is virtual reality so important?
VR will transform the world in which we live, changing how we spend our time, how we understand ourselves, and how we interact with others. It will impact every area of our lives – business, education, entertainment, and relationships.

Are we really going to spend most of our time in virtual environments?
We already do. We already spend a great deal of our time on the telephone, using a computer, or watching TV – so the idea that we will spend nearly all of our time in virtual environments is not as strange as it first seems. In fact, it seems like a probable state of affairs. The Virtual World is going to be a pretty exciting place and you are not going to want to miss out.

But, will virtual reality really be as good as the real world?
If virtual environments are unable to re-create the richness of ordinary experience, they will not be altogether satisfying. But flight simulators are already nearly indistinguishable from the real . . . and in time, virtual reality will be almost indistinguishable from the real, at least from the perspective of cognitive and sensory processing.
