Virtual reality (VR) is a place where real reality is no longer visible and you are completely immersed until you forget the real world. One has the feeling of being truly present in this world by being completely transported and having behaviours the same as we would really have even if it is all created on the computer. It is a new way of relating to virtual objects, in fact, to move we will move our legs and we will have to keep our balance so as not to end up on the ground, being able to operate levers, for example, by grabbing and pulling them. Born in the 1960s, it was in 1978 that it underwent major development with flight simulators in the American Air Force laboratories which saw the coining of the term virtual reality by Jaron Lanier in 1986.
Today the areas of application of virtual reality are very varied: entertainment and culture with the possibility of virtually visiting museums, theatres while remaining completely involved in what we have around us with an active role. The same thing also happens in video games where you no longer play seated but standing and physically moving with positive effects on health. Another use takes place within schools that have begun to include virtual reality in teaching processes, also giving life to virtual laboratories, but also in the field of architecture where it is possible to see in 3D the final result of a work that we have in advance. budgeted. In this way, it is possible to make changes to the initial project to have a real idea of the finished work.
Even the process of creating and forming product prototypes today passes through virtual reality which is also a much cheaper way than the traditional one. In marketing today, the possibility for the end-user to see the products in 3D is a fundamental sales key, which makes them more desired because you have the feeling of having them in front of you as in a real store. In the military field, it is also mainly used to train soldiers in all situations without actually risking death with simulations of armed conflicts, flying or driving.
In medicine, then, thanks to the use of virtual reality, great progress has been made. We have cybertherapy that was created to help patients in the psychological and rehabilitation fields, stimulating multisensory experience monitoring reactions and creating specific programs to improve health conditions. Virtual reality is then used to train future doctors to operate in the operating room or to treat people suffering from various types of problems to be healed. A real Hitech medicine that now joins traditional medicine.
