In a few decades, the world has changed dramatically. If earlier human life proceeded in a three-dimensional coordinate system that determined a four-dimensional space, now space is at least five-dimensional and in the coordinate system a new coordinate has been added to time and extent, measuring bits.

In recent years, the development of information technology has made it possible to create technical and psychological phenomena, which in the popular and scientific literature are called "virtual reality" and "cyberspace". The development of programming techniques, the rapid growth in the performance of semiconductor microcircuits, the development of special means of transmitting information to a person, as well as feedback - all this has created a new quality of perception and experience, realized as virtual realities. The external effect was that a person got into a world, either very similar to the real one, or previously conceived, written by a programmer, or received new opportunities in terms of thinking and behavior. The most impressive achievement of the new information technology, of course, is the ability for a person who has entered the virtual world not only to observe and experience, but to act independently. As a matter of fact, a person could, and quite easily, get into the world of virtual reality before, for example, plunging into the contemplation of a picture, a movie, or simply reading a book with enthusiasm. However, in all such cases, the activity of a person was limited by his position as a spectator or reader, and as for him, he could not join the action as an active character.

Adapted programs of virtual reality allow you to look into the digital world through the eyes of an ordinary person. To create a sense of presence, certain sensors and transmitters are used, which are synthesized and transmitted to the program for creating a virtual reality system. In other words, all actions that take place in the real world (taking into account the reactions of a person to events inside a programmed digital reality - VR) find their response and display in a visible image.

The digital world created by specialized virtual reality technologies is created using a fairly complex system of programs and signal interaction. Special cascading devices for connecting to Virtual Reality (VR) are limited to a special helmet only in the case of entertainment or introductory programs. For a closer acquaintance with the digital world of the virtual program, complex systems of sensors and display devices are used. What is VR - is it the ability to fly on a fabulous dragon from the comfort of your home sofa for gamers or the design of a spaceship right in space for scientists.

Notice that virtual reality is a digitally created world or limited space. At the same time, augmented reality technologies have become widely used in the modern world, but augmented reality and virtual reality are completely different technologies. Virtual reality and augmented reality create digitally displayed objects that are not available for display or interaction without gadgets, but augmented reality creates these objects directly in a person's field of view. For example, augmented reality can display a recipe for making great pasta on your kitchen wall, while you manipulate your kitchen utensils while in that very ordinary kitchen. VR technology, in turn, will simulate the kitchen, the pasta, and the kitchen tools.

Types of virtual reality

There are types of virtual reality systems that are used in entertainment and scientific fields:

- Augmented - the virtual reality system does not distort the usual view of the world, but only supplements it with artificially created elements. This is how the artificial and real world are integrated.

- Mixed - here there is a binding of artificially created elements to the real world, which creates a greater degree of realism.

- Virtual - all elements are the fruit of the developers' imagination. With the help of special devices, a person can fully immerse himself in an imaginary world.

There is no doubt that the further development and proliferation of virtual technologies can lead to radical changes in the scientific and technological sphere, as well as entail significant social transformations. Perhaps we cannot even imagine what the true state of affairs will be in, say, a few decades in this connection. However, there are various predictions, made by both scientists and fiction writers who love this now fertile topic, that are of interest to consider.

The direction of technical development of BP systems in the near future is easy enough to predict. Obviously, it will go in the direction of improving the capabilities of graphic display, and at the same time - the gradual cheapening of systems. Although there are also different views on this. For example, at a seminar on virtual reality in 1992, the main motive was the following: "Since the image quality is quite low, let us assume that for our purposes and good images are not necessary. We don't need real time computation or realistic textures." This was exactly the same situation in computer graphics in the early days of its foggy adolescence. In those days, you could only count on completely static and monochrome images. The first ideas at the sight of such quality also sounded comforting, but not constructive: we do not need color or movement. Time has shown that as soon as color and motion became available to computer graphics, so immediately everyone began to prefer realistically moving pictures with good color resolution. It is clear that the same thing will happen with virtual reality.

There is a lot to talk about the prospects for the development of virtual reality. However, forecasts, as you know, are a thankless task, and only time will tell how things will turn out in reality: will our civilization enter a new stage of development, or, on the contrary, will be thrown back.

It is obvious that virtual technology - just like any other technology - brings with it not only many advantages, but also a whole bouquet of hitherto unknown problems. But progress is unstoppable, and it is clear that despite the claims of some technophobes, virtual reality will take its place in our lives one way or another. Therefore, it is up to the Man of Reason to use his mind to get the most out of new achievements (enjoying it, if possible) - but never to allow virtual reality to become an illusory substitute for the real world.
