Q.  What Is Virtual Reality?    

    Virtual reality (VR) refers to a computer-generated simulation in which a person can interact within an artificial three-dimensional environment using electronic devices, such as special Goggles with a screen or gloves fitted with sensors. In this simulated artificial environment, the user is able to have a realistic-feeling experience.

    The concept of virtual reality is built on the natural combination of two words: the virtual and the real. The former means “nearly” or “conceptually,” which leads to an experience that is near-reality through the use of technology. Software creates and serves up virtual worlds that are experienced by users who wear hardware devices such as goggles, headphones, and special gloves. Together, the user can view and interact with the virtual world as if from within.

    To understand virtual reality, let’s draw a parallel with real-world observations. We understand our surroundings through our senses and the perception mechanisms of our body. Senses include taste, touch, smell, sight, and hearing, as well as spatial awareness and balance. The inputs gathered by these senses are processed by our brains to make interpretations of the objective environment around us. Virtual reality attempts to create an illusory environment that can be presented to our senses with artificial information, making our minds believe it is a reality.

Application

1.      Entertainment  

 

        The potential of VR in entertainment is clear and huge as the entertainment industry is a multi-billion dollars and consumers are always interested on its novelty.
The VR video game world was popularized already by the Disney Movie Tron in 1982. Today the video games are explored in large and realism world through an avatar. In VR games, gamers can look in any direction or walk through the scene.

Hollywood movies offers increasing degrees of realism to make user feel like they are part of the scene. They let the user totally immerse in computer generated world with the help of HMD that supports a stereoscopic view of the scene accordingly to the user’s position and orientation enhanced by audio, haptic and sensory interfaces.

2.     Education

    In addition to creating social awareness, the first-person perspective could revolutionize education scenario we have today. Anything that is too dangerous, expensive, or impractical to do in reality, virtual reality is the solution. VR offers visualisation of geometric relationships in difficult concepts or data that are hard to interpret. If the real environment is costly or hazardous to health, VR is the best choice to understand and learn it. For example, flight simulation or firefighting, nuclear power plant safety, medical procedures etc are the training in VR which are useful for education. Not just these common uses, VR education includes history, anthropology and foreign language acquisition. Students can explore the streets in 17th-century, on different era rather than just reading a book.

 

3.     Health    

    VR technology can also help improve today’s distributed health care system, in which doctors train to perform routine medical procedures in remote communities around the world. Doctors can immerse themselves in 3D organ models that were generated from medical scan data for better planning and preparation for a medical procedure. It can also be used to explaining the patient and his family so that they make more informed decisions. VR can also provide therapy to people suffering from mental illness.

4.     Tourism and Advertisment  

  

    Virtual Reality has been used to create histrorical sites, which then enables users to experience it with comfort from your house. For instance you can even create the war that happened at and location and feel being in war.
