Originally called artificial reality or cyberspace, virtual reality is one that is generated by computers or computer systems, which project a scenario in which the user has the feeling of being, being able to interact in that new world and the objects that are there. find to a lesser or greater degree, according to the equipment available to you.
The ideal virtual reality would be one that allows interaction in the virtual world with all the senses. However, due to the high costs, most of the systems have focused on sight and hearing, some with advances in touch, lacking to incorporate smell and taste.
To create this sense of reality, different devices are necessary. In the first place there is the visualizer, glasses or virtual reality helmet, which is in charge of displaying the images and instead of filming with a single camera uses two, located at a certain distance from each other. The images from the left and right camera are sent to the left and right viewers, respectively. In this way, the individual experiences a strong sense of depth that gives the images realism.
Also, there are the gloves, which transmit the movements to the virtual hands. Thus, if the individual shakes his hands, the hands he sees in pictures will also shake. In addition, they return the feeling of pressure, giving the impression that something real is being touched.
On the other hand, there are the suits that record all the movements of the body and what is observed in a virtual way will respond to all the actions that are done in real life, such as walking, turning, jumping and running. And for the audio, headphones are used.
There are two types of virtual realities: immersive and semi-immersive, the first allows detaching from the real world and living another world through the use of different devices and the second allows virtual and auditory interaction with a virtual world, but without being immersed in it. The latter is seen in 3D video games and movies.
Virtual reality has been incorporated into different disciplines to facilitate study, work and even negotiations. For example, an architect can show the model of his building, without even starting to excavate, taking the projection of the success of his project and being able to make pre-sales.
It is also used for the training of apprentices (such as pilots, soldiers, astronauts, surgeons, among others), the creation of virtual environments (such as stores, museums, classrooms, among others) and CAD (computer-aided designs).
Finally, entertainment has been one of the industries that has benefited the most from virtual reality that today has been able to create video games, short films and movies.
