WHAT IS VIRTUAL REALITY? Virtual Reality refers to a high-end user
interface that involves real-time simulation and interactions through multiple
sensorial channels.
Virtual Reality means feeling an imaginary (virtual) 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.
Virtual Reality allows a user to interact with simulated environment, be it a real or imagined one.

HISTORY OF VIRTUAL REALITY ⮚1950’s visionary cinematographer Morton Heilig
built a single user console called Sensorama. This enabled
the user watch television in three dimensional ways.

⮚In 1961, Philco Corporation engineers developed the first
HMD known as the Headsight.

⮚It was in 1965 IVAN SUTHERLAND envisioned what he called the “Ultimate Display.” ⮚In 1988, commercial development of
VR began. ⮚In 1991, first commercial entertainment VR system "Virtuality" was
released.

TYPES OF VIRTUAL REALITY VR Systems can be divided into
three groups Non-immersive systems (like workstations) See information about the real
world, presented via computer - location based services, GIS . Augmented reality systems (like HMD) Stay in real world, but see simulated objects. Immersive systems (like CAVE) See simulated world and "be" in that simulated world.

Virtual Reality is a growing industry. PC and specialized
hardware are getting better, faster and cheaper because of
development in VR. In the past, computing power has doubled approximately every 18 months. If this is the case then we should have a computer powerful enough to run immersive VR programs in our own homes by the year 2037.
