The reality It is formed by what exists in an authentic or true way. Events that have an effective existence, and that are not part of fantasy or imagination, are real .

Virtual , meanwhile, is what has the virtue of generating a effect , but that does not come true. Therefore, this adjective tends to oppose the idea of real .

It could be said, therefore, that the idea of virtual reality it faces two concepts that are opposite or, at least, contradictory. However, the notion is very common to refer to that computer environment which represents, digitally, something that pretend to be real .

Through various computers and software, virtual reality generates a simulation of reality This means that the person using virtual reality (or that "Enter" in such an environment) he feels that he is interacting with real elements, even if they are not physically.

Typically, the individual uses a helmet with a viewfinder that projects the images . You can also have various sensors in your clothes to interact with the virtual environment.

More and more progress is being made in this area. Thus, for example, in 2015 different steps have been carried out that have made this type of technology grow:
-The Vive helmet is presented, made by HTC and Valve Software, which allows whoever wears it can even move through different spaces.
-The Oculus company carries out the launch of its first virtual consumer helmet, which has to be connected to a computer, as well as complementary controls, which allow moving objects.
- Jump is released, a camera that allows you to record virtual reality videos.
-Samsung begins to market its Gear VR virtual reality headset, which uses the same brand smartphone as a processing unit.

Virtual reality has sparked an intense debate in society, with its advantages and disadvantages being analyzed with interest. In favor are attributed pros like these:
-It is very useful to train certain professionals who do not have to be in danger or in complicated situations during their student stage. We are referring to aviation, architecture or medicine, for example.
-It becomes a very useful tool for those who, due to illnesses, cannot leave their homes, since it allows them, from the four walls where they are, to be able to know cities or spaces around the world that they would like to visit.
- Within the field of medicine, it has become an effective resource for certain patients when it comes to recovering from powerful injuries.

Virtual reality can be used in the professional training or as entertainment, in the manner of a videogame . The idea is that the person feel that it is part of the world that you see through the viewfinder. When virtual reality is used for training purposes, the system tries to reproduce the real world in detail: in this way, the pilot who practices in a virtual reality simulator will find the same conditions that he will have to face on top of the plane.
