The Internet has become a parallel universe where almost everyone spends a lot of time. Once the creation of a worldwide network was considered a breakthrough, an unprecedented progress of human thought in the field of technology, but now we have gone a step further.
In this article, experts from Malone Trading invite you to get acquainted with virtual reality – the technologies of our present and future.
What virtual reality is
This term means a virtual world created using various technical means, transmitted to humans through a system of analyzers in our body, that is, through hearing, sight, touch, and even smell. For the creation of virtual reality, different studies according to the behavior of various objects of our reality under certain conditions, and under various influences on these objects were conducted. This information was carefully selected and analyzed, and then became part of the virtual world with the conclusion to the real world through certain technologies.
Technologies for immersing a person in virtual reality
- HMD-display
The working process of this equipment is quite simple. A helmet consists of one or more displays, a lens system to adjust the geometry of the image so that the house, for example, is not smaller than a person, and a tracking system – mechanisms that compile a report on the position of the helmet in space, which just helps to feel in virtual reality like in the real world.
The tracking system resembles the operation of a gyroscope or accelerometer, which allows you to determine the position of the body controlled by them in space, relative to all known main coordinate axes.
- MotionParallax3D-displays
These devices can be either in the form of a display similar to the television in our apartment, or in the form of specially equipped rooms in which sensors are installed that track the position of a person in this room, and depending on this, change the position of virtual reality objects.
The features of these devices are that this system uses such a mechanism of perception of volume as the parallax of movement. In simple terms, the system calculates your coordinates at a given time and reproduces the image at such an angle and in such volumes that they would be in our real world when you were at a certain distance from them (which the system calculated) and looked to objects at a certain angle (which the system calculated).
- Virtual retinal display
This amazing technology reproduces the image directly on the retina, which allows you to see the object of virtual/augmented reality in all colors. Experts from Malone Trading think that this device cannot be called virtual reality just because the projected object is still in our reality, although it is not real. Only under certain conditions, a good darkening of the space, with the help of these devices can you plunge into the world of virtual reality.
