FINAL ESSAY

VIRTUAL REALITY

Virtual reality (VR) is also known as Virtual Environment (VE) which basically means Real time interactive graphics with 3D models that is combined with a display technology which gives the user the immersion in the model world and direct manipulation (Fuch 1992), occupations such as architecture, engineering and interior designing would be difficult to imagine without graphical workstations. This essay will mainly talk about the history of virtual reality, future development possible on this topic, advantages and disadvantages of VR.

The main idea of virtual reality had started in 1929 and since then there have been a number of developments that took place in this technology. A simple mechanical flight stimulator which was developed by Edward Link to train the pilots at stationary (Sherman R.W. Craig A.B. 2003). Which was the first step towards the technology virtual reality, then Morton Heilig in 1956 had created a multi-sensory simulator, it was a pre-recorded film in stereo and colour and also added with scent, wind, binaural sound, and vibration experiences which was called Sensorama (Sherman R.W. Craig A.B. 2003). After that there were a number of developments such as the Ultimate Display (1965) by Ivan Sutherland and Videoplace (1975) by Myron Krueger. Then came Augmented Reality(AR) which was one of the biggest development in VR, AR is a technology that presents a virtual world which enriches rather that replacing the real world (Mazuryk T. Gervautz M. 1996). VR can be used at an important tool in number of places, both in professional field as well as entertainment such as VR are used in stimulators which are for entertainment and can also be used for training pilots, car drivers, it can also be used in education so that the students can virtually experience whatever they learn which makes it more effective for them and it can also be used in gaming for entertainment which has completely changed the face of gaming (Satava R.M. 1996).

       

  VR is an excellent technology that has a number of advantages, however this technology also has some disadvantages also such as people start staying in a virtual world more than real which could affect his social and mental health, people start experiencing headache, blurred vision, visual fatigue and difficulty in focusing being in a virtual environment for a long time (Griffin J.; Lewis C.H. (1997)). In conclusion, VR is a positive technology that can change the way of living of a person, making it easier and safer. People can now do the thing they dream, visit places without actually travelling which make is more cost efficient
