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.
