OCULUS VIRTUAL REALITY DEFINITION BASIC DEFINITION OF VR

HOW VIRTUAL REALITY WORKS ?

TYPES OF VIRTUAL REALITY

* IMMERSIVE VIRTUAL REALITY

* NON-IMMERSIVE VIRTUAL REALITYHISTORYTHE CONCEPT OF VIRUAL REALITY IS BASICALLY FROM 1950.

THEN IN 1965-ULTIMATE DISPLAY.

1966 HMD WAS INVENTED.

PEOPLE BECAME AWARE OF VR IN 1990s.What is Virtual Reality ?Virtual reality is, plainly speaking, seeing an imaginary world, rather than the real one. Seeing, hearing, smelling, testing, feeling. The imaginary world is a simulation running in a computer. The sense data is fed by some system to our brain.

A medium composed of interactive computer simulations giving users the feeling ofbeing present in the simulations.

RELATED TERMS WITH VR* ARTIFICIAL REALITY * AUGMENTED REALITY

Why Virtual Reality is needed?Scientific VisualizationScientific Visualization provides the researcher with immediate graphical feedback during the course of the computations and gives him/her the ability to 'steer' the solution process.Application at NASA Ames Research Center is the Virtual Planetary Exploration. It helps planetary geologists to remotely analyze the surface of a planet. They use VR techniques to roam planetary terrains.

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

non-immersive systems (like workstations). 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

Dangers of VR CONCLUSIONThe sole objective of virtual reality is to give the user an environment as realistic as possible and a thrilling sensory experience. The technology of virtual reality is advancing rapidly and it won't be long before it becomes a most exciting source of entertainment in our homes.REFERENCES"Facebook acquires Oculus VR for $2 Billion: Gaming Headset platform" March 26, 2014.
