Virtual reality technology creates a real-looking three-dimensional environment which you can interact with through VR accessories like headsets and controllers. The environment is different from one you would see in augmented reality because of the lack of interaction with the real world. In AR, objects are visually shown on a real-world background, but in VR, the entire environment is simulated.
Virtual reality offers varying degrees of immersion in its environments. In some worlds, all you can do is look at the simulation and observe the environment, while in others, you can interact with the surrounding objects using sensors like in a boxing game.
Aside from the gaming industry, there are several other possibilities for VR such as in education, robotics, entertainment, sports, and healthcare. For example, VR technology is used in the training of medical professionals with surgery simulations for various scenarios.
