Virtual reality is a technique that increases the fidelity of expression to simulated objects. So, they can overcome the differences between reality and virtual systems. It includes various graphics and animations. Also, it enables virtual tenses to be produced. It is based on powerful computing technology that can support time graphics.

Virtual reality is the use of computer technology to create a simulated environment. Unlike traditional user interfaces, virtual reality places the user inside an experience. It can simulate as many senses as possible, such as vision, hearing, touch, and even smell. The computer is transformed into a gatekeeper to this artificial world. The only limits to near-real virtual reality experiences are the availability of content and cheap computing power. Through virtual reality, everything can be manipulated or executed in the direction desired by the user. The difference from 3D animation is that in real-time. A demonstrator can control the movement and operation of objects in a three-dimensional virtual space with his own judgment.

Designers who make virtual reality can enter the space themselves and make quick corrections and accurate designs in real-time. The work of transmitting stereoscopic images, changing the characteristics or location of interactive objects can be realistic. Virtual reality is used widely in various ways. It can be used in-game, education, and construction. In education, medical training was conducted by relaying surgical scenes in real-time through virtual reality technology in Royal London Hospital. In construction, it can be used as a design verification and building preview. Also, it can be used in taking virtual reality tours of Korea's first Western-style building at Deoksugung.

Virtual reality is used in many different ways such as games, education, and construction. The technology has been developing constantly. Maybe virtual reality will be used a lot by many people in a few years.
