Virtual reality (VR) Technology

Virtual reality Technology

In 1950s, flight simulators were built by US Air Force to train student pilots. In 1988, commercial development of VR began. In 1991, first commercial entertainment VR system was released.

Virtual Reality is a technology based on computer which assimilates specialized input and output devices by allowing the user to interact with and experience an artificial created environment as if 

they were in the real world.

A virtual reality system is also allowing the user to search and interact with a three dimensional virtual or artificial environment created by the designer. In the virtual world, the user can do all things similar to routine as throwing a tennis ball or as excellent as flying through space. And all these things can be made to occur only because of a hand gesture or a nod.

Virtual Reality is a three-dimensional computer based interactive environment which simulate reality. Virtual Reality can bring us into an imaginary world which appears exactly similar to our own world.

In practice, it is very difficult currently to get a high experience of virtual reality mostly because of technical limitations on processing power & image resolutions. However, those limitations are expected to eventually be overcome by use of more powerful, cost effective processor and imaging technologies over time.

NEED OF VIRTUAL REALITY

Virtual reality will be used in medicine, architecture and many other spheres of life. Virtual simulators for training future pilots and operators of NPP have existed for a long time. It gives them an opportunity to test themselves in true to life situations. They can also improve their skills without fear to fail.

1) Simulate the real world dynamically by use of computer software, hardware and virtual world integration technologies.

2) Can pretend to have physical presence in places in the real world as well as in imaginary worlds.

3) Without any real danger. we can be part of the action on the virtual safe environment.

4) Virtual reality can help us to visualize working environment where people cannot go especially mars or low temperature environment by making same atmospheric conditions by use of computer graphics software and use of headsets, gloves etc. & make them feel same physical presence.
