How Virtual Reality Glasses Work

Virtual reality means the world created with the help of technical devices, which a person can feel with sight, hearing, as well as touch and smell. In this case, the user is literally immersed in this world, as he develops certain reactions to everything that happens in it.

For example, the user, playing games with VR helmet, will experience more emotions than without it. This fact is confirmed by the experiment, which was carried out by scientists and in which 1500 people took part – they were offered to play scary online games. As a result, when playing without a VR helmet, 8% of the participants experienced a sense of fear, while when playing in the headset their number increased to 80%.

Who Created Virtual Reality?

The first model of VR glasses was created in 1968 by a scientist from the United States, Sutherland. This device allowed you to watch low-quality graphics, and the construction of the device was so massive that it had to be fixed to the ceiling.

In the 1990s, when this direction was considered very promising, VR glasses were created for the SegaMegaDrive and Atari JaguarVR. But by the beginning of the new millennium, their relevance had dropped, and in 2000 virtual reality was forgotten about altogether.

They started talking about it again in 2012, when engineers Lucky and Carmack created Oculus Rift glasses. Prior to that, in 2011, a virtual reality fanatic Lucky created the first prototype, he wanted to get a better picture than the previous models. Since then, virtual reality has become very much in demand.

How does the VR headset work?

Not long ago, it was very expensive to look at the virtual world. But progress is moving forward, and now the virtual world is slowly becoming accessible to all segments of the population. The cheapest VR goggles are currently available for phones. In general, it is not very correct to call this device goggles. For this we need to understand how virtual reality glasses work.

First it is necessary to find out what such a device is. Many people have known about the VR helmet for PC for a long time. It is quite a complex electronic device, it consists of a plastic body and fixing straps.

The helmet is put on your head and connects to a personal computer, netbook or laptop. In his body built into special lenses, behind them is a small display, divided into two parts. Some devices use two displays. The image on them is the same, but due to the fact that each eye sees a separate picture, it creates a three-dimensional image effect.

For the user to navigate well in the virtual space and control it, it is necessary that the helmet can clearly read the movements of the head. To do this, a gyroscope is installed in it. Today, new phones are also equipped with the same gyroscope, and we will talk about that below.

Additionally, VR helmets are often equipped with special sensors that monitor head movements. The data read out by the sensors is sent via a USB or HDMI cord to the computer.

In general, this is the whole construction of the helmet. Due to the fact that all these elements are combined in one device, the headset has a high price, which makes it unaffordable for all segments of the population.

Why do I need a VR helmet for my phone?

Everything seems clear with the construction of a helmet for the PC. But how do virtual reality glasses for a smartphone work? These devices are optimal and affordable for many people.

As you have already understood from the above material, to create a VR helmet requires combining in the headset:

• lenses;
• screen (display);
• gyroscope;
• directly to the body.

The peculiarity of the headset for the phone is that the smartphone acts as the display and gyroscope here. It only remains to add to it the case and the lenses. Because of this idea, the price of this device is small, unlike the cost of a PC helmet. So you can buy VR glasses, put your phone in their case, adjust the lenses for a quality picture, and run the necessary program.

As a result, we get a full-fledged, quite functional VR helmet that costs less than similar equipment for the PC.

In the process of choosing, you need to pay attention to the compatibility of your phone with virtual reality glasses. Many VR glasses are universal, but there are some models that work with just one or two phones, and are not compatible with the rest.

Key Features:

• can only work with the phone;
• image quality depends on the phone’s hardware and display;
• riftcat vridge program allows you to play games designed for VR helmet designed for PC;
• it is possible to connect the phone to the PC;
• allow you to watch three-dimensional 3d-video;
• compatible with all vr applications.

A small disadvantage is that while the game industry in this area is underdeveloped, so games and programs for VR glasses, designed for phones, now a little. In particular, there are very few interesting games where it is possible to use such a headset. But this will eventually be resolved, as many developers are interested in this market.

The most popular models of VR glasses for smartphones

Since the appearance of the Cardboard from Google on the market, this segment began to develop rapidly. So now you can buy glasses with high-quality lenses, perfectly designed and very comfortable body, as well as with a secure attachment for fixing the device on the head, focusing, etc.

Today they are produced by many well-known corporations, so on sale there is a wide range of these devices, which differ in functionality, performance and build quality.

Therefore, any user can choose and purchase a more suitable model for themselves. But in any case you should study the instruction booklet, which is included with the device and which tells how to use all its features.

When choosing a headset, you need to consider such nuances:

• compatibility with your smartphone, the maximum image resolution (there are Chinese models that work only with a particular model of phone);
• The peculiarities of your vision – you should choose devices with adjustable lenses because if your vision of each eye is different, you will need separate focusing;
• Consider what you need your glasses for – to watch movies or play games;
• your financial capabilities.

With the final choice any buyer will decide for themselves, according to their needs and tastes, and most importantly – according to their financial capabilities.

Conclusions

To summarize, it is safe to say that VR glasses for phones have made the virtual world accessible to all mankind, as any owner of an inexpensive phone today can buy this device and plunge into the virtual game world or enjoy 3D movies of the highest quality.

But at the same time, virtual reality glasses for PC allow you to more fully experience all the possibilities of the virtual world.
