With the increasing popularity of computers and the Internet in people's lives, the role they play is also getting bigger and bigger, gradually becoming an indispensable part of our lives; nowadays people can go to work and school at home. Slowly people hope that the computer gives us no longer a cold screen, but hope that it can live up, let us feel a real world. Virtual reality technology is the product of this requirement.

Everyone may have played video games, and in many of them you have to act as a character, both in terms of passing and driving. A lot of very good video games can not only give us a lot of real feelings, but also to stimulate our intelligence. In fact, video games are a simple form of virtual reality.

But today's virtual reality is far from what we want. Although the computer can produce very realistic three-dimensional images, but we still know that it is not true, we are facing the computer is still a cold, rigid machine, which gives us in addition to a variety of information, and can not bring us how much of the real feeling. A flower appears on the screen, we can not smell its fragrance, not to mention imagine that you can use your hand to touch it, reach out to us can only be hard to touch the screen.

The famous American movie "The Matrix" has been seen by all of us, and this movie has won many fans because of its bizarre fantasy of the future. The movie envisions a future where humans can live entirely in virtual reality, where everyone can perceive a colorful world just by lying there. After watching the movie we wonder if this will become a reality? Perhaps the nanobots of the future will give us the answer. By placing a nanobot in a location where the brain connects to every neuron in all the sensory organs (i.e., eyes, ears, skin), it will be able to suppress all the information coming from the real senses and replace them with virtual appropriate signals. Scientists anticipate that by utilizing the above technology, humans will enter a virtual reality environment. The nanorobots implanted in the human body will generate a stream of sensory information that replaces the real senses, thus creating an immersive virtual environment. This takes what was previously a fantasy and makes it a reality.

The application of this technology will allow us to experience virtual reality with other people (or simulated people) without the need for any prior equipment in the human brain. Not only that, but this virtual reality will be as real as reality and more accessible, so you don't have to call your friends to meet them at a cafe in Paris or walk along a virtual Mediterranean beach. At home, you can turn on your computer and lie down to climb Mount Everest, visit the pyramids, or even travel in space. In short, you can do everything you want.
