Virtual reality by Anil Kumar
- 3. VIRTUAL REALITY Virtual reality is computer generated multi-sensory information program which tracks a user in real time. It is a technology which allow user to visualize, manipulate and interact with a computer simulated environment. Virtual reality is, plainly speaking, Seeing, hearing, smelling, testing, feeling an imaginary world, rather than the real one. The imaginary world is a simulation running in a computer. The sense data is fed by some system to our brain.
- 4. 1960 - The beginnings of VR. 1962 - Morton Heilig created a multi-sensory simulator. 1977 - Interaction through body movement 1982 - The first computer- generated movie 1983 - First virtual Environment. 1992 - A look at the possible negative side of VR. 1995 - Virtual Reality Modeling Language.
- 5. 1. NON-IMMERSIVE SYSTEM 2. AUGMENTED SYSTEM 3. IMMERSIVE SYSTEM
- 6. NON IMMERSIVE SYSTEM It is “through the window” system. It involves displaying virtual world on a screen without surrounding the user.
- 7. Augmented reality Augmented reality (AR) is a term for a live direct or an indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input, such as sound or graphics, haptic feedback. User Stay in real world, but see simulated objects
- 8. IMMERSIVE SYSTEM A type of VR in which the user becomes immersed (deeply involved) in a virtual world. The CAVE (Cave Automatic Virtual Environment) provides the illusion of immersion by projecting stereo images on the walls and floor of a room-sized cube. User See simulated world and "be" in that simulated world.
- 10. MEDICINE Practice performing surgery. Perform surgery on a remote patient. Teach new skills in a safe, controlled environment
- 11. EDUCATION AND TRAINING • Driving simulators • Flight simulators • Ship simulators • Tank simulators
- 12. • Designers can interactively test a building before construction begins. • Allow designers and clients to examine homes and office buildings, inside and out, before they're built.
- 14. INPUT DEVICES
- 15. OUTPUT DEVICES
- 16. ADVANTAGES
- 17. DISADVANTAGES VR replacing reality. Disengagement with real world. People preferring VR to reality. Difficulty of distinguishing between virtual and real, ‘false realities represented in VR. Lack of standardization of hardware and protocols Possible impacts on real body
- 18. FUTURE 1999 10% of the world's computing power was ● non-human 2029 99% of the world's computing capacity ● will be non-human we should have computers powerful enough to run immersive VR programs in every home by the year 2037.
