6. Define VR
Burdea: Virtual reality is a high-end user-computer interface that involves real-time simulation and interactions through multiple sensorial channels. These sensorial modalities are visual, auditory, tactile, smell, and taste.

Channels
Immersion – believing you are there

8. Ivan Sutherland’s The Ultimate Display
“Don’t think of that thing as a screen, think of it as a window, a window through which one looks into a virtual world. The challenge to computer graphics is to make that virtual world look real, sound real, move and respond to interaction in real time, and even feel real.”

9. Virtual Reality
Ideal for VR is that everything you experience is computer-generated.
