Let's have a closer look at virtual reality, or simply VR, first. It is an artificial, digital simulation or recreation of a real life environment of situation. It give users a feeling of first-hand experience of simulated reality via stimulating their vision and hearing. VR is typically achieved by a set of special equipment accessing your eyes and ears. The magic canvas behind it is VRML(Virtual Reality Modeling Language) code, which enables coders to create series of images, and outcomes of specific interactions with those images.
The most popular brand in this segment is, of course, Oculus Rift, acquired by Facebook. Its announcement of public launch in 2016 blew up minds of gamers all over the world. However, it can be used not only for games. Basically there are two directions of VR use. First one is entertainment including playing games and watching 3D movies. Another one is simulation of some certain environment for professional training. Such approach may be successfully used for training pilots, drivers and etc.
