Virtual reality (VR) is a technology which allows a user to interact with a computer-simulated environment, whether that
environment is a simulation of the real world or an imaginary world. It is the key to experiencing, feeling and touching the past, present and
the future. It is the medium of creating our own world, our own customized reality. It could range from creating a video game to having a
virtual stroll around the universe, from walking through our own dream house to experiencing a walk on an alien planet. With virtual reality,
we can experience the most intimidating and gruelling situations by playing safe and with a learning perspective.

Nowadays it becomes possible even for an average user, to move into the world of computer graphics. This fascination with a new (ir) reality often starts with computer games and lasts forever. It allows to see the surrounding world in other dimension and to experience things that are not accessible in real life or even not yet created. Moreover, the world of three-dimensional graphics has neither borders nor constraints and can be created and manipulated by ourselves as we wish – we can enhance it by a fourth dimension: the dimension of our imagination But not enough: people always want more. They want to step into this world and interact with it – instead of just watching a picture on the monitor. This technology which becomes overwhelmingly popular and fashionable in current decade is called Virtual Reality (VR). Virtual reality is considered to have begun in the 1950’s but it came to the public’s attention in the late 1980’s and 1990’s. This can be attributed to pioneering computer scientist Jaron Lanier who introduced the world back in 1987 to the term ‘virtual reality’. Research into virtual reality continued into the 1990’s and that combined with the appearance of films such as The Lawnmower Man helped to raise its profile. Most virtual reality environments are primarily visual experi- ences, displayed either on a computer screen or through special stereoscopic displays.
