<strong>Essay about Virtual Reality (VR)</strong>
Virtual reality is a three-dimensional computer environment that interacts with a person: a person is immersed in this environment using various devices (helmets, glasses, etc.), is part of the virtual world, and controls virtual objects and objects.
The idea of immersing a person in the surrounding non-physical environment arose in the Middle Ages in the field of art. Then concave frescoes were created in order to involve a person in what is happening in the image. In the 1830s, the first stereoscopes were created, the principle of which was to place two pictures depicting the same situation from different positions in space in different eyepieces.
Thus, one eye saw one picture, the other saw another, and the brain later combined them into a general three-dimensional picture. Nowadays, the same principle of obtaining a three-dimensional image is often used, only smartphones and LCD displays are used instead of pictures. After stereoscopes in the 1920s, the first flight simulators were invented, special devices that allow you to work out all actions when controlling an aircraft. Such simulators were mainly used by the military to train and improve the skills of military personnel. In 1982, the world's first laboratory dedicated to the research and development of virtual reality devices was established in the United States.
During the first decade of the 21st century, virtual reality did not gain popularity, but since 2012 VR devices have been actively gaining popularity in the entertainment industry. In 2012, a virtual reality glasses startup Oculus VR was introduced on Kickstarter, which was later bought by Facebook. After the emerging demand for glasses, many IT companies, including Google, Apple, Amazon, Microsoft, Sony and Samsung, HTC, Sony and others, began to develop their own gadgets.
