Virtual reality technology concerns a computer technology based on a simulated environment that places the user inside the experience. The user thus interacts with the virtual environment in three-dimension worlds (3D world).
VR technology by simulation involves, apart from the vision, many more senses such as hearing, touching etc. The use of more than one of the senses leads to more effective brain involvement, thus developing the emotional involvement of the individual. On the basis of this, the use of VR has gone beyond its use in games and entertainment and is employed for educational and professional use.
The most recognizable component in VR technology is the head mounted display (HMD) which has a small screen in front of the eyes and covers the peripheral vision. This technology is equipped with additional hand controls designed to give the user an extra kinesiological focus.
