  WHAT IS VIRTUALREALITY?  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.

  Why Virtual Realityis needed? • Education and training They also allow the simulation of dangerous scenarios not allowable with real aircraft. There are still many examples of people working in dangerous or hardship environments that could benefit from the use of VR-mediated teleportation. The most common example is the flight simulator. Application at NASA Ames Research Center is the Virtual Planetary Exploration.

  HISTORY OF VIRTUALREALITY 1950’s visionary cinematographer Morton Heilig built a single user console called Sensorama. This enabled the user watch television in three dimensional ways.

  In 1961, PhilcoCorporation engineers developed the first HMD known as the Headsight.

  It was in1965 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.

  TYPES OF VIRTUALREALITY 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.

  APPLICATIONS OF VIRTUALREALITY 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.
• 15.
  Training: • Virtual realityenvironments have been used for training simulators. • Examples include flight simulators, battlefield simulators for soldiers,paratrooping.
• 16.
  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.
• 17.
  Medical: • Healthcare isone 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.
• 18.
  Entertainment: • The entertainmentindustry 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
• 19.
  CONCLUSION • Virtual Realityis 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.
