Appearance story
The boom of virtual reality began in the United States in the early nineties of the last century. He significantly raised the rating of the gaming industry. In 1995, Nintendo launched the first device, called the Virtoal boy. This device was simultaneously a computer reality helmet and a virtual console. The picture in this gadget was transmitted using two monochrome black and red projectors. To create the illusion of volume in the device, the parallax effect was used . The image was transmitted with a resolution of 384 by 224 points. The advanced development at that time could not achieve popularity among users. A year later, its production was curtailed.
In 1997, Sony began creating virtual reality devices. Its developers have created several models of a miniature helmet Glasstron. These devices were equipped with headphones and LCD displays. However, they did not last long in the market. A little later, the company began to release a line of the latest virtual helmets. But in this case too, failure awaited her.
Today, virtual reality is returning to us again. Manufacturers offer their customers helmets of virtual reality, with which everyone can plunge into an illusory world. Such equipment has become much more convenient and lighter, and pictures - sharper and brighter. In addition, the purchase of a personal device to create amazing virtual reality is now affordable for almost every consumer. The name of the gadget "helmet" is very conditional. Modern lightweight models are more like glasses.

The tracker should be aimed at the person, which will fix the user's position in space. Such a sensor is necessary for games in which freedom of movement is allowed.

The negative side of virtual hardware from Samsung
What disappoint users with virtual reality glasses? Reviews of potential buyers relate to the high cost of equipment from Samsung. The device costs around $ 250, and for its operation it is necessary to have a smartphone of the same company Samsung Galaxy S6.
Acceptable Alternative

Reviews already bought such a device indicate its availability. The cost of such equipment is in the range of 2500 rubles.
What explains the fact that VR Box virtual reality glasses belong to such a low price category? Reviews of experts explain that this equipment is the creation of Chinese designers and engineers who have already created the second version of the budget version of such a device. However, users need not worry. The low cost of virtual glasses does not mean their low quality. The fact is that equipment from major world manufacturers is literally crammed with expensive speakers, processors and video cards from the manufacturer. Chinese 3D VR Box virtual reality glasses have a much more austere design. The reviews of experts indicate that the most expensive element of such equipment is high-quality lenses. Electronics in such glasses is completely absent.
Chinese VR gadget design
The budget version of virtual glasses reveals its functionality through minimal costs. What is the main structural difference between the VR Box virtual reality glasses? User reviews indicate that they do not have their own display. The function of this part is completely assigned to the smartphone screen.
Compared with the first version, the design of the front panel of this helmet is devoid of sharp corners. A small but very pleasant addition is the sliding cover. It is necessary to switch to game mode. In the first version, such a cover was located inconveniently for the user. It was difficult to disconnect from the case.

How will the 3D effect be achieved? When entering VR mode, two images will appear on the phone’s screen, duplicating each other. The left picture will fall on the left lens. Right, respectively, to the right. Due to a small bias, the human brain will perceive the resulting image in 3D. It should be borne in mind that a PC can only be used if the game supports gyro technology, that is, it performs equipment orientation in space.
In general, users are satisfied with the points for creating virtual reality from a Chinese manufacturer. Their only drawback is the lack of speakers, which are easily replaced by their own headphones. The rest of the helmet is comfortable and user friendly. And this VR gadget attracts potential buyers with its price, which is ten times lower than that of equipment from leading manufacturers.
