The so-called virtual reality, as the name suggests, is the virtual and reality combined with each other. Theoretically speaking, virtual reality technology (VR) is a computer simulation system that can create and experience a virtual world, which utilizes computers to generate a simulated environment that immerses the user in the environment. Virtual reality technology is the use of real-life data, electronic signals generated by computer technology, combined with a variety of output devices so that it can be transformed into a phenomenon that people can feel, these phenomena can be real objects in reality, or can be invisible to the naked eye of the material, through the three-dimensional modeling performance. Because these phenomena are not what we can see directly, but through computer technology to simulate the real world, so it is called virtual reality.
Virtual reality technology has been recognized by more and more people, users can experience the most realistic feelings in the virtual reality world, the authenticity of its simulated environment and the real world is difficult to distinguish between the real and the fake, so people have a kind of immersive feeling; at the same time, virtual reality has all the perceptual functions owned by human beings, such as auditory, visual, tactile, gustatory, olfactory and other perceptual systems; finally, it has a superb simulation system, truly realizing human-computer interaction, so that people in the process of operation, can operate at will and get the most realistic feedback of the environment. It is the existence, multi-sensory, interactive and other characteristics of virtual reality technology that make it loved by many people.
The arrival of the 5G era is destined to fulfill virtual reality technology. The future trend of life will be more switching between virtual and reality.
