Virtual Reality briefly represented by VR, is the human efforts to remove the boundaries between real and virtual space.
In other words, this technology makes it possible for a person to feel confronted a virtual environment in a real environment.
In Virtual Reality, the virtual environment is placed in front of the user’s eyes, and the user can interact with his surrounding by moving his head and body in that environment.
In the virtual reality the human brain is deceived, for example, while standing on the ground, feels it is at high altitude.
How to use Virtual Reality
The use of this technology usually happens with the use of Virtual Reality headsets. Some of the images and spaces used in it are computer graphics and 3D graphics, and others include 360-degree video or 360-degree imagery that has been pre-filmed from real-world environments.
By means of this technology, it allows people who can’t visit a certain place, to be able to put themselves in that environment.
Of course, this happens in a very natural way, so that the human brain believes that it is in the environment and has a unique experience.
This event is usually visualized. For example, suppose you want to travel to the summit of Damavand by Virtual Reality; This will happen visually and you get a fantastic experience and feel trully that place but you can’t experience weather or temperature or some of the environmental factors which you feel in reality.
Of course, we should mention that in some virtual reality headsets, it’s also possible to hear the sound of the simulated environment.
Virtual Reality environments are constantly evolving and in addition to the several advantages they offer,they can be very harmful.
But in general, we can say, by considering the advantages and disadvantages of this technology, we can achieve constructive achievements in different fields.
