What do you consider when you hear the words virtual reality ?

Do you envision somebody   wearing a cumbersome helmet  cap connected to a PC with a thick link? 

virtual reality is the computer-generated simulation of a three-dimensional image or environment that can be interacted with in a seemingly real or physical way by a person using special electronic equipment, such as a helmet with a screen inside or gloves fitted with sensors.

In 1938, Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double is the earliest published use of the term "virtual reality".

The meaning of virtual reality comes, actually, from the definitions for both "virtual" and 'reality'. The meaning of "virtual" is close and the truth is the thing that we encounter as individuals. So the term 'virtual reality' fundamentally signifies 'close reality'. This could, obviously, mean anything other than it as a rule alludes to a particular kind of reality imitating.

The first use of a VR presentation in a heritage application was in 1994, when a museum visitor interpretation provided an interactive "walk-through" of a 3D reconstruction of Dudley Castle in England as it was in 1550. This consisted of a computer controlled laserdisc-based system designed by British-based engineer Colin Johnson. The system was featured in a conference held by the British Museum in November 1994, and in the subsequent technical paper, Imaging the Past – Electronic Imaging and Computer Graphics in Museums and Archaeology

We know the world through our senses and precipitation system  . In school we all discovered that we have five detects: taste, touch, notice, sight and hearing. These are however just our most evident sense organs. Actually people have numerous a greater number of faculties than this, for example, a feeling of parity for instance. These other tactile inputs, in addition to some uncommon handling of tangible data by our brains guarantees that we have a rich stream of data from the earth to our psyches. 

Everything that we think about our world stops by method for our faculties. At the end of the day, our whole experience of the truth is basically a mix of tangible data and our brains sense-production instruments for that data. It makes sense then, that on the off chance that you can give your faculties made-up data, 

your view of reality   would likewise change in light of it. You would be given a rendition of reality that isn't generally there, yet from your point of view it would be seen as genuine. Something we would allude to as a virtual reality.
