Virtual Reality is in general a 3 dimensional (3-D) scenario, which the person operating it can intervene or make changes.

How does it work?

Virtual reality is a computer-generated world that gives a person a 3-D environment, where a person feels that all things same as the real world exist. To provide this type of technology scientists and software engineers developed their applications and device more powerful day by day to give better experience.

Uses of Virtual Reality

  1. Education

In the Educational field, VR plays an important role because some of the jobs are too risky and dangerous where training is more important before joining the job like –  brain surgery, the proper landing of a jumbo jet, parachute jumping, etc. Training is more important in this kind of job and for this virtual reality is used.

  • Web-based

There was a time when virtual reality used to be the fastest-growing technology but in the early 1990s, WWW(World Wide Web)  gain more popularity. Due to this VR technology development speed slowed down although Computer scientists find the technique to create Virtual world on the web it could not run much.

  • Augmented Reality

Augmented reality is used to create real-life environments in front of us this all done with the help of digitally images and take information in the environment to do work. Example Best example is POKEMON GO mobile game which was augmented reality technology-based.
