Virtual Reality

  1. 1. 1 Prepared By: Ali Raza Jamro (09) © Ali Raza (09)
  2. 2. Content 2        What is Virtual Reality? History Of Virtual Reality Application of Virtual Reality Virtual Reality Types Virtual Reality Devices Advantages And Dis advantages of Virtual Reality Virtual Reality Developing Software's © Ali Raza (09)
  3. 3. W hat is Virtual Reality ? 3   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. A computer generated multi-sensory information program which tracks a user in real time. © Ali Raza (09)
  4. 4. History 4 © Ali Raza (09)
  5. 5. Virtual Reality Applications 5  VIRTUAL REALITY IN MILITARY  VIRTUAL REALITY IN MEDICAL  VIRTUAL REALITY IN GAMES  VIRTUAL REALITY IN MOVIES © Ali Raza (09)
  6. 6. Virtual Reality In Military 6 United States: The military used it as flight simulators to train pilots. © Ali Raza (09)
  7. 7. Virtual Reality In Medical 7  The medical application of VR was stimulated initially by the need of medical staff to visualize complex medical data, particularly during surgery and for surgery planning, and for medical education and training. © Ali Raza (09)
  8. 8. Virtual Reality Systems 8  VR Systems can be divided into three groups  non-immersive systems (like workstations) S inform ee ation about the real world, presented via com puter location based services, GIS.  hybrid systems (graphics on top of real world) also called: Augmented reality systems S in real world, but see sim tay ulated objects  immersive systems (like HMD or CAVE) See sim ulated world and "be" in that sim ulated world © Ali Raza (09)
  9. 9. Non-immersive systems “Through- the - window” Large display, but doesn’t surround the user. 9 © Ali Raza (09)
  10. 10. Augmented reality Stay in real world, but see simulated objects 10 Information Visualization © Ali Raza (09)
  11. 11. More Augmented reality Stay in real world, but see simulated objects AR Museums 11 © Ali Raza (09)
  12. 12. Immersive systems (CAVE) S sim ee ulated world and "be" in that sim ulated 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. Several persons wearing lightweight stereo glasses can enter and walk freely inside the CAVE. © Ali Raza (09) 12
  13. 13. CAVE Pictures See simulated world and "be" in that simulated world 13 © Ali Raza (09)
  14. 14. Devices used in VR 14  INPUT DEVICES  OUTPUT DEVICES  Input Devices  TRACKERS  JOYSTICKS  MICE © Ali Raza (09)
  15. 15. Output Devices HEAD MOUNTED DISPLAY © Ali Raza (09) 15
  16. 16. Output Devices 16  THE POWER WALL © Ali Raza (09)
  17. 17. Output Devices 17 DATA GLOVES DATA SUIT © Ali Raza (09)
  18. 18. Advantage and Dis advantages Of V.R 18 Advantages of VR  Training  Risk-free experience  Experiencing things you wouldn’t normally be able to experience  Entertainment; fun, artistic expression. Dis Advantages of VR  Disengagement with real world.  VR replacing reality.  People preferring VR to reality.  Difficulty of distinguishing between virtual and real, ‘false realities represented in VR.  Possible impacts on real body © Ali Raza (09)
  19. 19. Virtual Reality Developing Software's 19      CURRENT SOFTWARE FOR VIRTUAL REALITY QUICKTIME VR PLUG-INS METAFLASH 3D MINOLTA 3D VRML (Virtual Reality Modeling Language) © Ali Raza (09)
