  What is VirtualReality or VR? Computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors. 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.

  History of VirtualReality In 1950s, Flight simulators were built by the US Air Force to train student pilots. Visionary cinematographer Morton Heilig built a single user console called Sensorama.This enabled the user watch television in three dimensional ways. Simulation that contained Stereoscopic images, motion chair, audio, temperature changes, odours, and blown air.

  Why Virtual Realityis needed? • Operations in dangerous environments There are still many examples of people working in dangerous or hardship environments that could benefit from the use ofVR-mediated teleportation. Workers in radioactive, space, or toxic environments could be relocated to the safety of aVR environment where they could 'handle' any hazardous materials without any real danger using teleoperation or telepresence .

  Why Virtual Realityis needed? ScientificVisualization ScientificVisualization provides the researcher with immediate graphical feedback during the course of the computations and gives him/her the ability to 'steer' the solution process.

  Why Virtual Realityis needed? Application at NASA Ames Research Center is theVirtual Planetary Exploration. It helps planetary geologists to remotely analyze the surface of a planet.They useVR techniques to roam planetary terrains.

  Why Virtual Realityis needed? Medicine Until now experimental research and education in medicine was mainly based on dissection and study of plastic models. Computerized 3D human models provide a new approach to research and education in medicine. Experimenting medical research with virtual patients will be a reality.

  Why Virtual Realityis needed? We will be able to create not only realistic looking virtual patients, but also histological and bone structures.With the simulation of the entire physiology of the human body,

  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 . hybrid systems (graphics on top of real world) also called: Augmented reality systems Stay in real world, but see simulated objects immersive systems (like HMD or CAVE ) See simulated world and "be" in that simulated world.

  Devices used inVirtual Reality  HEAD MOUNTED DISPLAY (HMD)  CAVE AUTOMATIC VIRTUAL ENVIRONMENT (CAVE)  DATA GLOVES  DATA SUIT

  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.

  Conclusion Virtual Reality isa growing industry.  PC and specialized hardware are getting better, faster and cheaper because of development inVR.  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 immersiveVR programs in our own homes by the year 2037.
