Meaning of Virtual Reality

Virtual reality (VR) is a computer-generated simulation in which a person can interact within an artificial three-dimensional environment where the individual's movements are captured using special electronic devices. The devices include special goggles having a screen or gloves that are fitted with sensors.

The user can explore the various artefacts and proceedings as they might in the real world within a simulated artificial environment.

Virtual Reality Explained with Examples

The term virtual reality was born by the natural combination of two words: virtual and reality. Virtual means "nearly" or "conceptually," that leads to the idea of directing an experience that is near-reality.

One can understand virtual reality by drawing a parallel line with real-world observations where one can perceive the surroundings through his senses and the perception mechanisms of his body.

Senses include touch, taste, smell, hearing, and sight. The inputs gathered by these senses are processed by their brains to make interpretations.

Virtual reality tries to create an imaginary environment presented to one's senses with artificial information, making one's minds believe it is almost a reality.

Explained with an Example

The most simple example of VR is a three dimensional (3D) movie. Through the special 3D glasses, one gets the hypnotic experience of forming part of the movie with on-spot presence. A person falling from a tree appears realistic to the viewer.

Importantly, the sound and light effects of a 3D movie have some impact on one's hearing and visionary senses. The senses believe that it's all happening right in front of him/her, although nothing exists in physical reality.

Technological Advancements

Technological advancements have allowed further enhancement ahead of the standard 3D glasses. VR headsets are available to explore virtual reality even deeper. Supported by computer systems, one can now play "real" badminton right in their living room. It can happen by holding sensor-fitted racquets for playing within a computer-controlled game simulation.

The helmet-like VR headset that players wear like goggles provides an illusion of being in a badminton court. They make moves as well as try to strike according to the speed and direction of the incoming ball.

The precision of the shot is estimated by the game-controlling computer, which tracks the game. It also assesses whether the ball was hit too hard and went out of bounds or was it too soft to hit the net.

Other benefits of this VR technology cover training and simulation. For instance, those needing drivers license can get a first-hand practice of driving on the road using a VR setup. It involves handling car parts such as steering wheel, brake, and accelerator.

It avoids accidents and enables the first level of learning so that students can get accustomed to driving before actually hitting the road.

Further, real estate sellers have incorporated VR-aided apartment or house walkthroughs to provide a feel of property without the need to travel.
