Immersion

From 3D on a screen to Virtual Reality

Most often we present 3-dimensional graphics on 2-dimensional displays.
What is the potential for presenting 3D information in a way that it can be percieved as 3D?

Virtual Reality = Computer Graphics in Real Time + Immersion + Interaction + other perceptive feedback (touch, sound, smell...)

Terminology by K.-P. Beier
The term 'Virtual Reality' (VR) was initially coined by Jaron Lanier, founder of VPL Research (1989). Other related terms include 'Artificial Reality' (Myron Krueger, 1970s), 'Cyberspace' (William Gibson, 1984), and, more recently, 'Virtual Worlds' and 'Virtual Environments' (1990s).
Today, 'Virtual Reality' is used in a variety of ways and often in a confusing and misleading manner. Originally, the term referred to 'Immersive Virtual Reality.' In immersive VR, the user becomes fully immersed in an artificial, three-dimensional world that is completely generated by a computer.
