- 4. In 1938,French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double, is the earliest published use of the term "virtual reality". The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s. The term "virtual reality" was first used in a science fiction context in The Judas Mandala, a 1982 novel by Damien Broderick. Widespread adaption of the term "virtual reality" in the popular media is attributed to Jaron Lanier, who in the late 1980
- 5. Virtual Reality meansfeeling the imaginary(virtual) world, Rather than real one. The imaginary world is a simulation running in a computer Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels.
- 6. Virtual Realityis the term is used for computer generated 3D environments that allow the user to enter and interact with the alternate realties. The definition of “virtual” is near and “reality” means what we experience as a human being.
- 7. Why VR? VR is able to immerse you in a computer-generated world of your own making: a room, a city, the interior of human body. With VR, you can explore any uncharted territory of the human imagination.
- 8. In 1957visionary cinematography “Morton Heilig” built a single user console called Sensorama. This enabled the user watch television in 3 dimensional ways.
- 10. The Virtual RealitySystem works on the following principle - It tracks the physical movements in the real world, then a rendering computer redraws the virtual world to reflects those movements. The updated virtual world is sent to the output (to the user in the real world). In this case, the output is sent back to a head mounted display. Hence, The user feels "immersed" in the virtual world - as if she was in the virtual world itself as all she can see is her rendered movements in the virtual world.

- 13. Desktop basedvirtual reality involves displaying a 3 dimensional virtual on regular desktop without any specialized movement tracking enviroments.
- 14. Large displaybut doesn’t surround the user. It uses the video cameras to track the image of the users in a virtual world where you can also pick up or move objects.
- 15. Immersion intovirtual reality is a perception of being physically present in a non-physical world. Elements of virtual environments that increases the immersiveness of the experience: 1. Continuity of surroundings 2. Conformance to human vision 3. Freedom of movement 4. Physical interaction 5. Physical feedback

- 26. Advantages Disadvantages Virtualreality creates a realistic world. It enables user to explore places. Through virtual reality user can experiment with an artificial environment. Virtual Reality make the education more easy and comfortable. The equipments used in the virtual reality and very expensive. It consists of complex technology In Virtual Reality environment we cant move by our own like in the real world.
- 27. Virtual Realityis a growing technology. PC and specialized hardware are getting better and faster because of development in VR. May be 3D interfaces will replace the windows based ones? Huge demand for VRML(Virtual Reality Modeling Language) Programmers in near future. Revolution in gaming industries.
- 29. VR introducesa new way of interacting with computers. The best of VR is yet to come. Web is very suitable for VR applications, but the proper technology is not yet there.
