Virtual Reality-Seminar presentation

  1. 1. SEMINAR PRESENTATION ON VIRTUAL REALITY Presented By SHREYANSH 1209113095 Department of Information Technology
  2. 2. OVERVIEW  What is Virtual Reality?  History of Virtual Reality Types of Virtual Reality  Devices used in Virtual Reality  Applications of Virtual Reality  Conclusion
  3. 3. WHAT IS VIRTUAL REALITY?  Virtual Reality refers to a high-end user interface that involves real-time simulation and interactions through multiple sensorial channels.  Virtual Reality means feeling an imaginary (virtual) 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.  Virtual Reality allows a user to interact with a computer- simulated environment, be it a real or imagined one.
  4. 4. HISTORY OF VIRTUAL REALITY 1950’s visionary cinematographer Morton Heilig 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.
  6. 6. It was in 1965 IVAN SUTHERLAND envisioned what he called the “Ultimate Display.” In 1988, commercial development of VR began. In 1991, first commercial entertainment VR system "Virtuality" was released.
  7. 7. TYPES OF VIRTUAL REALITY VR Systems can be divided into three groups • Non-immersive systems (like workstations) See information about the real world, presented via computer - location based services, GIS . • Augmented reality systems (like HMD) Stay in real world, but see simulated objects. • Immersive systems (like CAVE) See simulated world and "be" in that simulated world.
  8. 8. DEVICES USED IN VIRTUAL REALITY  HEAD MOUNTED DISPLAY (HMD)
  9. 9.  CAVE AUTOMATIC VIRTUAL ENVIRONMENT (CAVE)
  10. 10.  DATA GLOVES  DATA SUIT
  11. 11. APPLICATIONS OF VIRTUAL REALITY Business: • Virtual reality is being used in a number of ways by the business community which include: • Virtual tours of a business environment. • Training of new employees. • A 360 view of a product.
  12. 12. Training: • Virtual reality environments have been used for training simulators. • Examples include flight simulators, battlefield simulators for soldiers,paratrooping.
  13. 13. Engineering and Design: • VR is widely used in engineering and designing process. • It gives better understanding of the design and facilitates changes wherever necessary • It helps to reduce the time and cost factor. Examples: Building construction, car designing.
  14. 14. Medical: • Healthcare is one of the biggest adopters of virtual reality which encompasses surgery simulation, phobia treatment, robotic surgery and skills training. • VR finds its application in nursing, dentistry, health issues for the disabled.
  15. 15. Entertainment: • The entertainment industry is one of the most enthusiastic advocates of virtual reality, most noticeably in games and virtual worlds. • Virtual Museum, e.g. interactive exhibitions • Gaming • Virtual theme parks
  16. 16. 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.
