Virtual reality places people inside an immersive experience, simulating their physical presence in an environment. People feel they really are in the place and they can interact with the environment as if they were in a physical space.
The first and main application of virtual reality so far has been games. Non-gaming use of virtual reality is still considered an experimental technology, and it is mainly limited to certain sectors such as the military, health care and education.
Virtual reality will however soon enter the business world, changing in particular the way companies do sales and marketing and engage with their customers.
