- 16. VIRTUAL REALITY
- 17. • Virtual Reality is seeing an imaginary world rather than the real one. • The Imaginary World is a simulation running in a computer. The sense data is fed by some system to our brain. • A medium composed of interactive computer simulations giving users the feeling of being present in the simulations. • The GAMERS went crazy after the release of a VR device.
