  3. What Is Virtual Reality? Virtual Reality is the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside (HMD) or gloves fitted with sensors
  4. History of Virtual Reality 1950’s – The Sensorama Morton H Eilig’s was a visionary cinematographer who built a single user console called sensorama.This enable the user to watch television in three dimensional way. 1960 – First VR Headset Morton H Eilig’s next invention, this was very limited in its uses, with no sound, or any form of user interaction, just 3D vision. 1965 – The Ultimate Display This was a concept put forward by Ivan Sutherland, which was the blueprint of what we call VR today. He suggested a 3D world, maintained in real time, and the ability for the user to interact with it. 1987 – The term is “virtual reality” is coined Jaron Lanier coined the term virtual reality, and developed a range of expensive virtual reality gear. 1991 – VR Arcade Now players could use goggles, connect with one another and play video games.
  5. 1999 – The Matrix In 1999, film The Matrix hits theatres. The film features characters that are living in a fully simulated world, with many completely unaware that they do not live in the real world. Although some previous films had dabbled in depicting virtual reality, such as Tron in 1982 and Lawnmower Man in 1992, The Matrix has a major cultural impact and brought the topic of simulated reality into the mainstream. 21st Century VR With the rapid advancement of computer technology, and as devices get smaller and more powerful, VR developments are coming thick and fast. With big companies like Samsung and Google investing heavily in VR, and the Oculus Rift being valued at £2bn, it is expected that virtual reality will become more and more advanced.
  6. Types Of Virtual Reality I. Immersive VR II. Non Immersive VR III.Tele presence VR
  7. Immersive Virtual Reality Immersion into virtual reality is a perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment. Ex.HMD or CAVE.
  8. Non Immersive Virtual Reality Large display but does not surround the user. Desktops , LCD TV’s Ex.Playstations
  9. Tele presence Virtual Reality It is exactly what it sounds like: tele, “at a distance”, and presence, “being present”. The sensors are therefore controlled and operated remotely by the user. Consider bomb disposal robots, undersea exploration, and drones as being operated via telepresence VR.
  10. Devices Used In VR cave Data gloves Head mount display Data suits
  11. Applications Of Virtual Reality Used in games In medical science
  12. Used in education systems Used in air force training
  13. Pros And Cons Of Virtual Reality PROS CONS Virtual reality creates a realistic world. It enables user to explore places. It makes education more easy. Equipments used in VR is very expensive. In this technology we cant move as we can use in the real world.
  14. Future of Virtual Reality o Virtual reality is a growing industry. o 3D interfaces will replace the windows based ones. o Phone manufacturers will give free VR headsets. o Revolution in gaming industries. o Low price.
  15. Conclusion • As every generation is known by its technology. • For our parents it was internet , for us its I- phone • And for the future generation it will be virtual reality.
