  2. 2. OVERVIEW  Introduction  History of Virtual Reality.  Types Of Virtual Reality.  Architecture of VR  Working of VR.  Design of HMD  Oculus Rift.  How it works.  Virtual Reality Hardware.  Applications Of Virtual Reality.  Future Of Virtual Reality.
  3. 3. INTRODUCTION  Virtual Reality(VR)? Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels. Virtual reality is a computer generated world with which the user can interact. Interaction can vary from looking around to interactively modifying the world.
  4. 4. HISTORY OF VR 1950’s visionary cinematographer Morton H Eilig built a single user Console called Sensorama . This enabled the user watch television in three dimensional ways.
  5. 5.  In 1961, Philco Corporation engineers developed the first HMD known as the Headsight. HISTORY OF VR
  6. 6. TYPES OF VR SYSTEM  Immersive Virtual Reality  Augmented Virtual Reality  Desktop (Window on a World) Virtual Reality  Video Mapping Virtual Reality
  7. 7. IMMERSIVE VR  It is basically a feeling of involvement of the user in the virtual world .  The user has no visual contact with the physical word.  Often equipped with a Head Mounted Display.  This unique combinations where the user can immerse as well interact with the simulations is known as Telepresence
  8. 8. DESKTOP VR  Desktop-based virtual reality involves displaying a 3-dimensional virtual world on a regular desktop display without use of any specialized movement-tracking equipment.  Modern computer games can be used as an example
  9. 9. VIDEO MAPPING VR
  10. 10. ARCHITECTURE OF VR SYSTEM  Input Processor, Simulation Processor, Rendering Processor and World Database.
  11. 11. WORKING OF VR
  12. 12. DESIGN OF HMD
  13. 13. OCULUS RIFT
  14. 14. HOW IT WORKS ?
  15. 15. VR-HARDWARE  HMD’s  CAVE DATA GLOVES VR SIMULATORS
  16. 16. APPLICATIONS OF VIRTUAL REALITY  Entertainment  More vivid  Move exciting  More attractive  Medicine  Practice performing surgery.  Perform surgery on a remote patient.  Teach new skills in a safe, controlled environment.
  17. 17. APPLICATIONS OF VIRTUAL REALITY  Manufacturing  Easy to modify  Low cost  High efficient  Education & Training  Driving simulators.  Flight simulators.  Ship simulators.  Tank simulators.
  18. 18. CONCLUSION • Virtual Reality is a growing industry. • PC and specialized hardware are getting better, faster and cheaper because of development in VR. • In the past, computing power has doubled approximately every 18 months. If this is the case then we should have a computer powerful enough to run immersive VR programs in our own homes by the year 2037.
