Virtual Reality – Opportunities and Challenges

Abstract

In today’s world , we are surrounded by blends of technologies. We have acquired majorities of these technologies into our everyday lives. Increasingly, these various technologies are getting integrated to provide us with new abilities and services. And most often a computer is the heart of such integration. This is the case with Virtual Reality a so called technology which actually is a very sophisticated integration of a number of techno-logies. 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 a imaginary world which appears exactly similar to our own world. For designing a virtual reality system , one have to deals with ideas of spatial relationships and computer graphics which in turn are affiliated to mathematics , physics , arts and also human psychology. In these virtual or synthetic environ-ments , one have to take into account various physics laws like gravity , air resistance , and speed etc.
