Virtual reality glasses: where are they used and how do they work?

What is virtual reality?

Before talking about virtuality glasses, let’s outline what these devices interact with. The term “virtual reality”, contrary to stereotypical ideas, does not only refer to computers. The word “virtuality” arose a long time ago, but had a different meaning.

Ancient people did not know how virtual reality worked. Derived from the Greek v i r

, which means “man,” the word “virtuality” among the Romans meant “the totality of all male qualities.” And only with the spread of new technologies, the concept of “virtuality” began to expand in meaning.

What virtual reality is and how it works is not difficult to understand.

VR is a transfer into a simulation created using computer technology.

This way we get the opportunity to perceive the surrounding virtual space with our senses. Virtual reality devices become mediators in this process. The most accessible of them today are virtual glasses, which are often used together with joysticks and controllers.

Who created virtual reality glasses

The world first learned what virtual glasses are in the middle of the last century, in 1956. Then the first prototype arose, working in the same way as reality glasses work. Sensorama 3D devices

, which had a special display with a three-dimensional image. In addition, they were equipped with stereo sound, vibrating seats and even an odor generator. Cinematographer and director Morton Heilig, who created this unusual device, shot 6 films for it using a special camera.

Virtual reality glasses, as they are known today, became known only in 1982. This happened thanks to the RB2

. But 2 years earlier, a significant breakthrough was made by Steve Mann. He invented a computer system that connects to the helmet and viewfinder. The principle of the invention was also similar to how virtual glasses work. But at that time, the cost of acquisition was so high that it was not available to a person with an average salary. And the question of whether there are virtual reality glasses was asked much more often.

What are VR glasses for?

A wide circle learned about what Viar glasses are thanks to the gaming industry. In the early 10s of this century, video games tailored specifically for VR devices became more accessible and increased in number. But not only gamers know why virtual reality glasses are needed; these devices are also used for training and work. For example, for assembling parts, when all drawings and diagrams are transferred to the master’s display. Or in driving schools, where the effect of presence helps students better understand the situation on the road. Many students studying to become surgeons and airplane pilots have already tried out how virtual reality glasses work.

Where did the VR helmet come from?

A virtual helmet is a high-tech device that appeared along with glasses. Their difference lies in a larger set of functions, because The helmet includes both a display and headphones. This creates both an audio and visual effect of being in the simulation. The virtual gaming headset is one of the most famous versions of this device. If the gadget is equipped with a microphone, it is able to perceive and transmit even more information.

The first attempt to create such a helmet was made by an American company in the 90s, but it was not successful.

A little later Sony

tried to do the same, but the developments were again not widespread. Only a few knew how a virtual reality helmet works. Such equipment could only be used as an addition to training equipment for military personnel or pilots. But over time, the prototypes were refined and became more accessible.

How does VR work?

Virtual reality glasses are a product with a plastic case and a display. In front of it are lenses that divide the image in two. What VR glasses are is easy to understand by taking them apart. In reality, the design of virtual reality glasses cannot be called particularly complex. Through the lenses, an adapted image is transmitted to each eye. The cameras shoot separately for the right and left pupil, while the distance to the image is close to real. This creates the illusion of three-dimensionality.

Purpose of the gadget

The main function of 3D virtual reality glasses is to create a three-dimensional world in which the user is located. This could be a game, a movie or video, photographs, or even educational programs. Today, such devices are used to train drivers and improve their skills, to conduct virtual excursions in museums, and to educate children.

Important! It should be understood that a helmet, smartphone and laptop alone are not a sufficient condition for immersion in the virtual world. The device will not work without the appropriate content.

You will need to download special applications for your phone. In the case of photos and videos, they must also support this function. The requirements are similar for computers and game consoles. Not all games can be run in 3D, so when choosing, you need to pay attention to this criterion.

Types of VR devices

There are 2 main types of devices: real virtuality glasses and a VR helmet. They are similar in principle of operation, but have different capabilities and design.

Helmet

What is a virtual reality helmet? This is a more massive and functional product. It allows you to immerse yourself more fully in VR, but weighs more. To use this gadget you will need a space of at least 16 sq.m. Therefore, before purchasing, decide whether the premises have such capabilities. Having low mobility, the VR helmet nevertheless offers advanced capabilities.

Glasses

How do VR virtual reality glasses work? They are mobile, and their low weight makes them easy to transport. The most modern developments are distinguished by minimalism and compactness. But simple models like Google Glasses

have limited functions. Their purpose is only to display a three-dimensional and realistic image. Inexpensive virtual reality glasses are a good option for a beginner to try out a VR system.

What are the differences?

What makes a virtual reality helmet different and how this system works is determined by motion sensors. Devices for tracking them are located around the perimeter. Thanks to a variety of sensors, the player is able to approach, walk around or touch an object. If the playing space is small, you won’t be able to fully immerse yourself in the process. Also, the virtual reality helmet has 2 displays instead of 1, i.e. one for each eye. But the requirements for such a gadget are considerable. The cost is quite high, and only a powerful computer processor will ensure proper operation.

How virtual reality glasses work is determined by the gyroscope and accelerometer. These components help the device track the turns and tilts of the head. But a simple system will not be able to understand the position in space. Then movement in space occurs using the buttons on the joysticks. If you open the description of virtual glasses, it is easy to see the presence of only 1 display. And the picture is divided in two only thanks to the lenses. They, in turn, are adjusted to the characteristics of the interpupillary distance. Therefore, this option is considered budgetary and simpler.

How a modern VR headset works

All virtual reality helmets, no matter how much they cost, work on approximately the same principles. But the nuances can vary significantly. These are the ones we will discuss.

3D image is the basis of “immersion” in VR

If we don’t take Chinese plastic crafts like Cardboard, which Aliexpress is littered with, and we’re talking about serious “large” VR helmets with their own filling (both connected to a PC and standalone), then the screen built into the helmet is responsible for image formation ( or two screens, one per eye), on which two images are fed: for the left and right eyes. The screens themselves may have different resolutions. For example, the popular Oculus Rift S today has one screen with a resolution of 2560 by 1440 pixels and a refresh rate of 80 Hz.

We also look at the picture through lenses, as was the case in the first Carboards, only these lenses themselves are much larger, more expensive and clearer. As a rule, modern helmets use Fresnel lenses. They are light, clear over a fairly large area and are great for VR glasses.

Modern VR helmet Oculus Rift S

As a rule, the higher the screen resolution, the higher the price of the helmet, but also the less noticeable the so-called screenshot (or “mosquito net effect”) is when the eye sees the distance between individual pixels.

To understand what it is, take your smartphone and look at it through a magnifying glass. If the screen resolution is not particularly high, then the pixel grid will be visible quite clearly. This is one of the problems of modern VR helmets, and developers are struggling with it by increasing the resolution or coming up with all sorts of clever technologies for masking this effect (for example, the Samsung Odyssey Plus helmet has its own technology for hiding the visibility of pixels, and, according to users, it really works, really the picture becomes a little “soapy”). Obviously, defeating the screendoor is a matter of time.

Another problem is the limited viewing angle. Imagine that you are looking at the world through a ski or diving mask (on forums this is what they call the “diving mask effect”). Unfortunately, in current VR, a horizontal viewing angle of 90–110 degrees is considered normal. However, in active and exciting games you quickly stop paying attention to this effect.

New helmets like Pimax 5K/8K already have a viewing angle of 170-200 degrees. Another thing is that it turned out to have not quite the resolution that the manufacturer promised, and not exactly the panels. And the price of "Pimaks" is not very humane. In addition, the most popular mode among users is still 140 degrees of view, because even if modern video cards cope with two hundred, it is with great difficulty.

New "Pimaks" - helmets with a wide viewing angle

Head tracking in virtual reality

But it is not just a picture that achieves immersion into another world. After all, if we only have a 3D picture, then it is not much different from a regular cinema. In modern VR headsets, we can turn our heads in all directions, and at this moment the world will remain in its place - just like in reality!

Head rotations are now tracked using a gyroscope and angular accelerometers. The equipment built into helmets is usually more accurate than those found in phones. The helmet software reads the sensor readings at a very high frequency, and to the user the result looks like he is moving his head in reality. Head tilts are also tracked.

If you try to do a similar trick with Cardboard or other glasses for your phone, you will probably notice jerks when you turn your head and the “immersion” effect will begin to be lost. Excellent tracking is one of the main points in the debate between supporters of mobile VR and owners of more expensive PC headsets.

All cheap, simple helmets have this kind of tracking of head rotation in space, also called 3DoF (three degrees of freedom). In fact, this is the basis for the operation of any VR device.

If everything is approximately clear with the gyroscope, then what is much more interesting is the spatial tracking of the head position in VR, which is already implemented in expensive models of VR helmets (also known as “positioning”, or 6DoF). To understand what I'm talking about, imagine that in the world of VR you can not only turn your head, but also move it forward, backward, up, down, left and right.

For example, while standing still, you can put your head up to a poster on a virtual wall or, as in The Matrix, you can dodge a bullet by simply crouching or leaning back. “Positioning” is a new level of immersion. But how does it work?

There are two approaches here. The first type of tracking is used in early PC headsets like the Oculus Rift DK2/CV1 or Vive/Vive Pro. In the case of Oculuses, special sensor cameras are placed around the room (included with the helmet), which detect infrared radiation from emitters located on the helmet. In this way, it is possible to take into account the coordinates of the helmet in space.

Oculus Rift CV1 helmet and camera sensor for reading position in space

Vive and the now popular Valve Index have a similar tracking system, only they use base stations instead of cameras, and the system itself is based on lasers.

The main disadvantage of this type of tracking is that you need to place cameras or bases somewhere for the helmet to work correctly. In addition, there must be a certain distance between them. This is a problem if you have a small gaming area for VR or there is simply nowhere to attach the sensors.

the second type of spatial tracking comes to our aid , the so-called “tracking from the inside”, “tracking inside out” or “inside tracking”. Its essence is that cameras for determining position in space are built into the helmet itself. Next, they scan the surrounding environment and, based on its changes “on the fly,” they conclude that the user has moved his head.

The explanation may sound complicated, but this scheme works very effectively. And the first to use it were the guys from Microsoft, who came up with their Windows Mixed Reality technology. Based on it, several manufacturers have created their own versions of VR helmets.

Lenovo Explorer is one of the first WMR helmets with two cameras for positional tracking

This approach eliminates the need to arrange sensors or bases, and the kit with a helmet is significantly cheaper and smaller in size. Obviously, the more cameras on the helmet, the better they will track changes in position. The developers from Oculus developed this idea, and in the current Oculus Rift S we already have as many as five internal cameras, and in the Oculus Quest - four. At the same time, HTC engineers crammed as many as six cameras for positional tracking into their new Vive Cosmos helmet!

But happiness is not in the cells, or rather, not only in them.

Hand tracking in virtual reality

The first games for helmets connected to a PC were controlled either from a keyboard mouse or from a gamepad, like the one that comes with game consoles (for example, the Oculus CV1 came with an Xbox 360 gamepad). The situation changed with the release of HTC Vive, at the same time motion controllers began to be sold. These devices allow you to transmit information about hand position to a game or program. Next came the Oculus Touch controller for Oculus Rift CV1 and so on.

Oculus Touch VR controllers (version for Oculus Rift S) are still considered the most comfortable of their kind today

Today, the most progressive are the “brass knuckles” Valve Index Controllers. Their main feature is the ability to track not only the position of the hands, but also the position of each finger and the force of its pressing. True, there are no games yet that support this. Half-Life: Alyx should reveal the full potential of “brass knuckles”.

Below is a review of these controllers on one of the popular Russian-language YouTube channels dedicated to VR.

The tracking principle here is similar to the helmet position tracking scheme we have already discussed. You pick these things up and the “magic” begins (well, almost). For example, Oculus Touch has sensors installed inside the rings, the position of which is read by helmet cameras.

Which type of tracking is best?

It would seem that “tracking from the inside” is the most reasonable method and it is the future. But so far everything is not entirely clear.

Firstly, helmets with such tracking need good lighting so that the cameras can distinguish the surrounding reality, while the Oculus Rift CV1 could easily work in complete darkness.

Secondly, in the same shooters you need to aim as in reality, keeping your hands on the body of the virtual rifle and bringing them to your face (and this is very cool!). But it turns out that one hand covers the other, and the helmet cameras may incorrectly read the position of the controllers, causing the coordinates to get lost. However, this effect can be achieved even if the external sensors are placed incorrectly.

The same problem befalls a player who tries to get an arrow from a quiver in Skyrim or another similar game. The helmet cameras do not see the controllers when they are behind your back. Although if the movement is made quickly, then cunning predictive algorithms can come into play, which suggest where the controller has moved.

In general, there are not many games where there are moments that are poorly compatible with “tracking from the inside,” and therefore, when choosing a helmet, you can safely give preference to this technology.

“How to walk here”, or moving in VR

Another important point that remains for us to discuss is how to move in the virtual world. In general, nothing prevents you from simply walking around the room, and the cameras themselves will transfer our movement into VR. However, wait! In fact, a lot of things get in the way: furniture, walls and the length of the helmet wires, which require connection to a PC.

This is why most of the time in VR we still move using the buttons on the controllers. This can be compared to playing some RPG on a gamepad: tilt the stick forward - the character goes forward, tilt it back - the character goes back. The same thing happens in VR, but it also has its own characteristics.

Feature one: different controllers have different buttons for moving. We've already looked at Touch, but in the photo below are controllers from Vive, where instead of sticks we have touch pads that you need to press in the right direction or touch in the right place (depending on the game and how the developers implemented it).

Vive controllers and touch pad for moving in the center

These controllers are also called “sticks” (and “chops”), and you can argue a lot about their convenience, but it would be foolish to deny that they were the first on the market. Personally, I prefer to play on Touch sticks than on a pad like this. Valve engineers, working on the latest generation of controllers, also chose sticks, and for a reason.

Feature two: in games there are different patterns of player movement. The two most popular are teleports and locomotive (smooth movement).

Why such difficulties? The fact is that often, especially beginners, begin to feel sick in VR out of habit. In reality, you yourself stand still, but in VR your body seems to move, and this causes discomfort. To overcome this, they came up with movement using teleports.

It works something like this. You choose the direction where you want to move, point with the controller, press a button and instantly find yourself in the right place.

Moving using teleports using the example of the game Budget Cuts

This method really makes you feel less sick, but it’s not very convenient and really prevents you from completely immersing yourself in the game. Therefore, the preferred method is “smooth sliding”, when you press the stick or touchpad - and the movement begins in the chosen direction. It's ideal when game developers offer different methods of movement to choose from.

In some games, the right stick also allows you to rotate the camera, just like when playing on a regular console. Of course, it is much more interesting to move your head yourself, but sometimes, for example, you want to play while sitting and 360-degree movement is not available.

Types of virtual reality glasses

The division into types of virtual glasses is caused by their purpose. Advanced VIAR systems are able to interact not only with a PC, but also with any equipment. This includes TVs, mobile devices, tablets and consoles.

Television

Let's figure out how virtual reality glasses for TV work. Such accessories have been known for a long time and, in addition to television, are used in cinemas. 3D gadgets for watching movies look like ordinary glasses, but with special red-green lenses. They do not allow you to view objects from a 360 degree view. With their help, you can only see a three-dimensional picture while sitting still. A positive characteristic of this type of virtual reality glasses is that the eyes are less tired.

For smartphone or tablet

The newest version for these gadgets are special cases with lenses. They are selected according to the size of your smartphone or tablet. What you need for virtual reality glasses is to place the device in place of the display and secure it. As a rule, the main part of the gadget can be adjusted to size. We have collected the best virtual reality glasses for smartphones in one article.

Why do we need virtual glasses for a smartphone, how do such models work? If among the functions of a VR system there is support for mobile phones, this makes the phone universal and multifunctional. Virtual glasses for children are also popular. They must be chosen with a child's head in mind, which is the only difference from the adult versions.

For consoles and laptops

The devices for consoles and laptops are the same; they differ little from models for PCs. To play you will need a console and joysticks. Some apps allow you to connect controllers to track your hand movements. And in advanced versions, the operating principle of virtual reality glasses includes movement tracking. the HTC Vive VR gaming devices.

.

Augmented reality glasses

Many people do not understand the difference between virtual reality glasses and augmented reality glasses. But there is a significant difference. In the case of augmented reality, objects are superimposed on the real environment. Whereas in Viar there is a complete transfer to the simulation. Therefore, through AR it is impossible to achieve the same effect as in VR. Pokemon Go is a prime example of how augmented reality works.

Popular models

Since the advent of Cardboard from Google, glasses of this type have rapidly developed and spread.
Today they are equipped with high-quality lenses, a well-designed and comfortable body, reliable fastening to the head, and the ability to adjust the lenses to suit the user’s vision. Many companies have taken up their production, and there is a huge selection of different models of these simple and interesting devices on sale. A logical question arises: what can virtual glasses for a smartphone do, and what are the main differences between different models?

As in any other market segment, its leaders have appeared here. Some manufacturers focus on producing inexpensive budget versions, while others have concentrated their efforts on producing expensive options with many additional options.

Thus, the FiiT VR, VR Shinecon, as well as VR BOX 2 models, the cost of which can range from 1000 to 2000 rubles, confidently remain among the top products. They are distinguished by an excellent combination of quality and price, comfort and versatility. Among the more expensive models, we can highlight the Ling VR or Baofeng 4. Here you will have to pay about 4,000 rubles.

There is also a category of budget products on the market. This includes VIGICA and Ritech. The price of which is no more than 1000 rubles.

Is it worth buying?

Virtual reality glasses are used only in tandem with a computer or mobile device. This purchase can be considered successful for lovers of technological innovations. But users are still arguing about whether virtual reality glasses are harmful.

Advantages and disadvantages

Advantages:

1. New impressions from the game. The principle of virtual reality is that a person perceives the simulation as the real world. This multiplies the impressions of even minor incidents and actions in the game.
2. Improved reaction. Due to the full immersion effect, the player reacts instantly. Everything that happens in virtuality gets a special touch if you connect controllers. VR systems that track movement also help to warm up and develop creative thinking.
3. An opportunity to unwind and relax. Staring at a computer screen is not as exciting as immersing yourself in a fantasy world. Allowing you to feel the full range of emotions, glasses in the virtual world provide mental relief.

Flaws:

1. Threat to the nervous system. Do not buy a gadget for playing horror or other disturbing genres if you have a nervous disorder. If the plot contains negative aspects, a warning can be seen in the opening screensaver. For particularly impressionable people, a device such as virtual reality glasses can cause harm.
2. Load on the vestibular apparatus. The harm of virtual reality glasses is motion sickness after prolonged use. Dizziness, nausea, and disorientation are common symptoms. For people with a weak vestibular system, it is better to handle gadgets carefully or abandon them.
3. Expensive. Whether virtual glasses are so harmful is a controversial issue. But the considerable price of such a purchase is obvious. Not everyone can afford to buy VR, nor can they afford to buy a computer with a powerful processor for it.

Glasses for smartphones

One of the popular types of virtual reality glasses are products for smartphones. Such models have a lot of advantages. The first and main one is the absence of a huge number of wires. Customer reviews of such devices are mostly positive. But avoid products that are too cheap. Some little-known companies are looking to capitalize quickly on the growing popularity of VR on smartphones. Therefore, the performance of low-priced VR glasses may not be particularly impressive.

Computer helmets

VR systems in the form of helmets are an acquisition with prospects. Currently there are fewer games for him than usual. But every year, development companies are increasingly striving to implement Viar support in the program. To fully experience what virtual reality is and how it works, you will need space. If there is no free space in the apartment, it is better to refuse the purchase. Considering the high cost of such a gadget, it may turn out to be a waste of money. After all, some functions will become inaccessible to the user. But if you can move the furniture away or if you have a separate play space, the purchase will be worth it.

Pros and cons of VR glasses

VR tools are so popular among users for a reason. The constant improvement of models allows us to reach a new level of immersion and sensation of the virtual world. This is facilitated by:

1. Vivid impressions - the game’s actions are aimed at a smooth transition from the real to the simulation world. Which brings new emotions to the process even from simple movements within the virtual world.

2. Improvement of reaction - quick response to actions in the game. The actions taking place are especially susceptible when complementing VR glasses with gloves and joysticks. At the same time, there are other positive aspects: a person strengthens muscles, develops thinking.

3. The opportunity to switch gears and relax. Simply watching movies will not give you vivid impressions. Virtual reality glasses will help you get positive experiences that promote mental relaxation.

The positive aspects of using virtual reality glasses are known based on numerous reviews. But it is important to know about the disadvantages:

1. Negative impact on the nerves - playing in the world of fantasy and horror provokes the development of tension and frustration (violence, humiliation). It is advisable to replace them immediately when the device is turned off, especially if you have mental problems (the condition may worsen).

2. Load on the vestibular apparatus - obvious signs of dizziness, nausea and loss of reality, especially with frequent use of glasses. In case of such problems, it is recommended to use glasses for a short time or stop using them altogether.

3. High cost - few can afford virtual reality glasses, because in addition to the main device, powerful expensive additions may be needed: processors, accessories.

Technologies are constantly improving. It is possible that over time, techniques that do not affect health will appear in the world of simulations. Naturally, the positive aspects of using VR glasses outweigh the negative ones, which may be why virtual devices are so in demand.

Tips for choosing

New models of VR gadgets appear on the market every year. It is especially difficult to choose if a person is getting acquainted with this technology for the first time. You have to figure out on the spot how virtual reality glasses work and what they are. But the consultant’s main goal is to sell the product. And it often turns out that not all the functionality of an expensive purchase is necessary for the user.

These tips can help you make your choice:

1. Platform. There are devices on PCs, consoles, and smartphones. First, decide what you are going to connect the VR headset to.
2. Power. Before purchasing, make sure your computer or phone has enough power to support VR. To do this, you can take a free test on Steam
   . The way virtual reality glasses for a computer work may not please you if the performance is insufficient.
3. Specifications. Pay attention to FoV
   , Hz refresh rate, resolution, as well as
   PPI
   . The higher the scores, the better. With good characteristics, you won’t have to regret how VR glasses work after purchasing.

Be sure to check whether there is enough space for the headset you are purchasing. The recommended area is indicated in the instructions or description of the virtual reality glasses on the box. For example, for Oculus Rift

this is only 90x90 cm minimum, and for
PlayStation VR (PSVR)
- 3x3 m.

Mid-price devices: $50–200

What are they?

Such headsets also most often use a smartphone as a screen, but they try to attract a different category of buyers. Unlike the simple and rather clunky Cardboard, mid-priced glasses are equipped with additional sensors, more complex control mechanisms, the ability to adjust focus, or even their own screens.

Samsung Gear VR

The most famous among such devices are Samsung Gear VR and Google Daydream View, designed for Android smartphones. Alternatives from lesser-known developers like Homido VR, Merge VR, Carl Zeiss VR One Plus are compatible with both Android and iPhone. Recently, the list of mid-range devices was supplemented by the first standalone virtual reality headset Oculus GO, which works without any smartphones or other additional devices.

What makes them stand out?

Thanks to additional sensors, devices from this segment more accurately track head movements in space. This allows for smoother videos and greater interactivity in games. The illusion becomes more convincing. But you still shouldn’t expect the accuracy of premium models equipped with external sensors from such headsets.

Gadgets in this segment are usually sold together with a Bluetooth gamepad or remote control. This provides new control options that are especially useful for gamers. In addition, there are buttons or touch panels on the body of such glasses, with which you can control the basic functions of games and programs without additional devices.

Google Daydream View

Manufacturers of mid-priced glasses pay increased attention to content. Gear VR, Daydream and Oculus GO are entire ecosystems with various games, programs and films. Developers of other glasses are also trying to expand their range to please users.

What to pay attention to

When choosing a mid-priced VR helmet, make sure that it is equipped with additional sensors: an accelerometer, a gyroscope, a proximity sensor. Check to see if a gamepad or remote is included. Also, go to the manufacturer's website and see how many VR applications the glasses support. If you don’t need any of this, then you don’t need to overpay - you can take a simple Cardboard.

If you are looking for a device with a built-in display, consider its resolution: the higher the better. If you choose glasses for your smartphone or computer, check compatibility with the smartphone model or computer specifications on the website of the store/glasses manufacturer.

If your device is too weak or old and does not support VR headsets, consider buying standalone Oculus GO glasses. They have a built-in 5.5-inch display with a resolution of 2,560 × 1,440 pixels and a quad-core Qualcomm Snapdragon 821 processor with 3 GB of RAM.

Oculus GO

You will still need a smartphone (Android or iPhone) to set up Oculus GO and install new programs on them. But you can use these applications on glasses without the help of a computer or smartphone. The helmet runs Android 7.1. The version with 32 GB of internal memory costs $199, with 64 GB – $249.

Obviously, you should pay attention to the design and weight of the headset. If you don’t have the opportunity to touch and put on the device before purchasing to feel it for yourself, you can at least read reviews from other buyers.

If you are nearsighted or farsighted, it is better to choose a device with a focal length adjuster.

Rating of the best glasses and helmets 2019

There are a number of proven VR devices that have achieved reliable status in the market. If you have little knowledge about what virtual reality glasses are, it is better to choose from the list. This reduces the risk of stumbling upon a low-quality fake.

For console

Sony Playstation VR. This device is created exclusively for the Sony PlayStation 4 and PlayStation 4 Pro game consoles. Therefore, you won’t be able to buy the headset separately from the set-top box. The design has a display with a refresh rate of 90-120 Hz and a built-in microphone. The only drawback is the low resolution of 960 by 1080.

Autonomous glasses on Android

Oculus Go. This headset is completely autonomous and has no wires. It has 4 built-in sensors: accelerometer, gyroscope, magnetometer and presence sensor. In addition, the model is equipped with integrated speakers with support for 3D sound and a microphone. The name speaks for itself. With this device you can learn what virtual reality is and how it works, anywhere.

How to choose VR glasses

The user experience depends directly on the correct purchase. Choosing virtual reality glasses is not the easiest task, because there are many options and the cost varies greatly. The price depends directly on their quality and purpose. Obviously, phone models cannot provide the same experience as gaming consoles or laptops. The price tag of models for mobile gadgets varies from several hundred rubles to several thousand. Helmets for PCs and consoles are much more expensive, and their purchase will cost several tens of thousands.

Glasses for smartphone

When purchasing for a smartphone, there are several parameters to consider.

1. Operating system type – for iOS or Android, as well as their versions.
2. Supported diagonal.
3. Viewing angles - the higher they are, the more the user can see around him.
4. Weight – glasses should not be too heavy initially to be comfortable to use. This is especially true for options for children. The optimal value without taking into account the weight of the smartphone is 300-400 grams.
5. Control type. The first option is a gyroscope, in which case the user simply turns his head. The second option is glasses with a remote control that controls the character’s movement.
6. An important point is the design. It should be reliable and comfortable; today you can find options made of cardboard (the cheapest) or high-quality plastic with convenient fastenings and a layer that will soften the pressure of the device on the face.
7. When choosing, it is better to buy a model that can be used with headphones rather than a smartphone speaker.
8. For users who have vision problems (farsightedness or nearsightedness), it makes sense to buy a model with adjustable focal length.

Advice! If the phone is not fast enough and slows down, you can think about purchasing a standalone VR with an Android screen, a built-in chipset and its own memory. A good example is Oculus Go. These are glasses that can work independently; the only caveat is that you will need a smartphone to set up this device and download new applications to it.

For laptop or console

Models for laptops or consoles are presented in three types - Oculus Rift, HTC Vive, Sony PlayStation VR . The latter option is designed specifically for fourth-generation Sony consoles, and its availability is a requirement for their use.

The first two options require a laptop or PC running Windows or an Xbox One console, while serious requirements are placed on the PC - from a powerful processor to a video card.

Advice! Before purchasing, you should study the minimum requirements and draw a conclusion about the advisability of the purchase, since the laptop may simply not be able to support them.

In addition, free space is required, because a special system tracks the player’s movements. It will be very uncomfortable to play with such a helmet in a small room. The kit also includes joysticks for VR glasses or controllers with which the user performs various actions in the game.

What devices do not need to be taken?

If you want to check how virtual reality glasses for your phone work, avoid cheap ones. Low-quality devices allow light to pass through and have a fragile body. With such shortcomings, the effect of complete immersion in virtuality will be ruined. The quality is different from how virtual reality glasses for a computer work. Even inexpensive computer gadgets are produced by well-known companies and are of appropriate quality.

To immerse yourself in virtual reality, glasses must meet modern standards. Outdated generations of VR systems are still available for purchase. For example, Oculus Rift dk. You should purchase them only with a clear understanding of what kind of VR glasses they are. Their low cost is due to low technical parameters, which are inferior to the standards of new generations. You can buy a gadget if these indicators are acceptable to you.

Lowest price category (up to $20)

Among virtual reality glasses of the lowest price category, I would like to highlight the great popularity of Google Cardboard 2.0.
A budget but high-quality device for the first experience of immersion in virtual reality is in demand among buyers as a holiday gift or birthday souvenir. Large companies order custom Cardboard branding for marketing and PR activities.

Design

You won't find anything surprising here. As a rule, devices in the lower price category are made of plastic or cardboard. They use simple lenses, and the screen is a smartphone display. Cheap and cheerful. A classic example of such a device is Google Cardboard.

By the way, Google launched sales of its virtual reality device before all its main competitors. Today Cardboard is a reference device in its price category. Many software manufacturers for iOS and Android follow Google's development.

Cardboard attracts users with its affordable price and minimal set of functions for a virtual reality device. However, in ergonomics the device is clearly inferior to more expensive competitors.

Price

This is where it gets more interesting. The starting price for the starter kit is only $5. Moreover, some large companies or stores may give Cardboard to their customers completely free of charge. The affordable price allows you to use the device in public events or advertising campaigns.

Additional expenses

To fully operate Cardboard, you only need a smartphone. Not the rarest item for 2021. The operating system does not matter; Cardboard is compatible with Android and iOS devices.

However, due to some reasons, Google releases updates to its Cardboard services for iOS with a slight delay.

Portability

Thanks to its clever design, Google Cardboard folds into a small box that is slightly larger than the size of a glasses case. When it comes to portability, Cardboard is head and shoulders above all of its competitors. But does everyone need this mobility? After all, we spend most of our gaming time sitting in a comfortable chair at home.

Control

The mobility of the device has a negative impact here. The user can adjust the direction of movement in the game by turning or tilting the head. For all other controls, only one small button is allocated. This is sorely lacking for full immersion into the game world.

Availability on the market

The cheapness of the device determines its availability on the market. In addition to Google Cardboard, users will be able to purchase its numerous analogues. Even though such devices are short-lived, you can always purchase a replacement for a broken or lost device.

These devices are available to users at a very interesting price - up to $20. They are compatible with Android and iOS smartphones and work with all Google Cardboard services, including viewing videos in virtual reality format.

Google Cardboard V1

The first version of virtual reality glasses from Google. This device is more difficult to assemble and does not support smartphones with large display sizes. Not all smartphones support Google Cardboard V1 controls (it uses a special magnetic button).

The main advantage of the device is its price - approximately $5. The first version of Cardboard is quite suitable for use in less interactive applications (virtual tours and watching videos).

The device weighs slightly less than its more modern counterpart. But the lenses in Cardboard V1 are noticeably worse - 25 mm, viewing angle - 90 degrees.

Google Cardboard 2.0

In the latest version of their device, Google specialists have improved ergonomics. Google Cardboard 2.0 supports custom-sized phones and has a built-in button on the top of the device.

In addition, engineers have simplified the process of assembling virtual reality glasses. However, the material of the device itself is still not processed in any way. Thick cardboard absorbs sweat well. This can be a serious cause of discomfort during prolonged use of the device. The average cost of Google Cardboard 2.0 is $15. This makes the device an ideal option for those who want to try out a virtual reality device for the first time.

Some companies have already started selling Cardboard 2.0 under their own brands. The weight of Cardboard directly depends on the smartphone you are using (the cardboard device itself is almost not felt on your head). The standard kit includes lenses (34mm) that expand viewing angles to 100 degrees.

Color Cross

Another affordable purchase option. Doesn't have the most pleasant appearance. However, in terms of ergonomics it is noticeably ahead of most competitors in its price category. Supports smartphones with a diagonal from 4 to 5.7 inches. The user will be able to customize Color Cross lenses to suit themselves.

The average price is $15, the weight of the device is ~ 200 grams.

Ritech 3D Glasses

The device is made of hard plastic. The use of mobile devices with display diagonals from 3.5 to 5.6 inches is supported. The average price is $12. The device does not have external controls, which is not critical for watching videos.

However, for games or other interactive applications, the user will need to buy a separate joystick. Ritech 3D Glasses supports lens distance adjustment.

The weight of the device without a smartphone is 250 grams.

VR Polarized 3D Glasses II

The device supports phones with large display diagonals. However, it is not clear from the description on the seller's website whether the VR Polarized 3D Glasses II supports lens customization.

The average price is $12. Weight - 400 grams.

Sali EVA 3D Glasses

Has the cutest design. The design is a complete copy of Google Cardboard V1. However, the construction of Sail EVA 3D Glasses uses stronger and lighter materials. The average price is $12. The device does not support customization of the lens or design elements.

Purple EVA 3D Glasses

The device is very similar to the Sali EVA 3D. It differs in some design elements and their colors. The average price is $12.

Hasbro My3D Viewer

The Hasbro My3D Viewer device has an interesting design, unlike its main competitors. The device works exclusively with iPhone and iPod (up to version 4G).

There are not as many applications available to work with Hasbro as we would like. The average price is $10. Prices for the device have dropped noticeably after the manufacturer's official website was closed.

PU Leather and Microfiber 3D Glasses

An ideal device for lovers of devices with an unusual design and construction material.

The body of the device is made of artificial leather and microfiber that is pleasant to the touch. In all other respects, it is a complete copy of Google CardBoard V1. The average price is $10.

Woody 3D Glasses

Another representative of devices made from materials unusual for such devices. Wooden analogue of Google CardBoard V1. The average price is $12.

VR Fold

Very lightweight foldable device. The user can customize the VR Fold's lenses, and when folded, the device fits in the palm of your hand. The device is sold in red and purple color options. The average price is $10. The VR Fold weighs only 76 grams.

Baofeng Small Mojing

Another very light virtual reality glasses from China. This time from Baofeng Moging. The device is foldable. The glasses come with a carrying case.

The average price is $15. Devices are available in blue, purple, orange and black colors. The weight of the device is 40 grams. Viewing angle: 90 degrees.

Homido Mini

The most compact device on the virtual reality glasses market from the French company Homido.

The average price is $15. These points add up. There is no carrying case included. Device weight ~ 15 grams.

Karas 3D

The colored body of the device has a minimalistic design. The average price is $15. The glasses support smartphones with screen sizes from 4 to 5.8 inches. The weight of the device is 225 grams.

Archgon VRock

Foldable analogue of Google Cardboard. Supports work with smartphones with display diagonals from 4.2 to 5.2 inches. Not suitable for use with iPhone 6.

The design of the glasses provides quick access to the smartphone screen. The average price is $20. The device is also available in black color. The weight of the device is 96 grams.

C1-Glass from Google Tech

Convenient and easy to use device. To control the glasses, a joystick is not necessary (you can press the smartphone screen). The average price is $18.

The glasses are available in green, white and red. The weight of the glasses is 28 grams. Viewing angle: 90 degrees.

What accessories are there for glasses?

You can control the gameplay with the mouse. But it's much more interesting to interact with the simulation using controllers. How do virtual glasses work together with special joysticks? The game becomes interactive, and the player ceases to be a mere observer. A huge advantage is that a person does not sit still during the process. This can solve the problem of stiff muscles and general body fatigue.

Gloves

The most motion-sensitive accessory is gloves. What is this for virtual glasses? The sensors in such a controller are located not only on the hands, but also on the fingers. Therefore, you can control the gameplay with maximum convenience. But the cost of this acquisition cannot be called small.

Joysticks

Joysticks are affordable. Virtual reality glasses, as well as their use, will become more multifaceted in function with controllers. Any joysticks can be connected to the VR system. But the ones that are relevant are those that are equipped with spatial tracking sensors, like Oculus Touch.

Joysticks for smartphones

Phone virtual reality glasses operate a little differently from computer glasses. On a smartphone, the touch control function becomes unavailable after pinning. Therefore, external remote controls or joysticks become mandatory. When purchasing an accessory, pay attention to the battery capacity. It would also be a good idea to check if your wireless connection is supported.

Top gloves and gamepads

Among the gloves, it is worth highlighting such models as:

• CaptoGlove;
• MANUS VR.

Among PC controllers, these accessories are popular:

• Razer Hydra PC;
• Oculus Touch;
• Controller for Xbox One.

For smartphones, the best choice would be:

• POWER A MOGA Pro Power;
• Samsung Smartphone Gamepad;
• SUNNYPEAK Wireless Bluetooth Gamepad.

There is no point in buying gloves for an inexpensive VR gadget for a mobile device. The advantage of how phone virtual reality glasses work is their simplicity. But additional accessories on a PC will never be superfluous.

Average price category (from $20 to $140)

Unlike Google Cardboard and its many analogues, mid-priced devices have many additional features in stock. They no longer look like a funny smartphone case (no offense, Google Cardboard).

Devices of this class can be equipped with their own display, additional controls and sensors. The most typical representative of mid-priced virtual reality devices is Gear VR from the South Korean company Samsung.

The functionality of devices in this price category may vary significantly.

Price

For such devices, the user will have to pay from $20 to $140. Believe me, you will not spend this money in vain. Manufacturers of these devices carefully monitor their products. Gear VR receives constant updates that improve the performance of the device.

The increased price allows for the use of advanced lens technology (devices from Zeiss) and the introduction of new controls (devices from Homido). Some Samsung smartphone bundles may come with free Gear VR.

Additional expenses

The use of these virtual reality devices implies the presence of flagship smartphones. It’s quite logical, because the functionality and graphics of Gear VR are noticeably different from the available Google Cardboard.

Portability

At first glance, devices in the mid-price category are the golden mean. They are quite portable, and at the same time offer the user wide functionality of use.

However, the realism of the virtual image or the rapid change of frames can cause dizziness. In addition, to fully transfer the user to virtual reality, it is necessary to use external cameras that will track the movement of the object in space.

Perhaps in the future this need will disappear, and only a smartphone camera will be enough to fully transfer the user.

Control

Control methods vary depending on the specific device model. In some devices it is simply missing. Others are limited to a simple two-button system. In our opinion, the most successful control system is equipped with Gear VR. The Samsung device uses a special trackpad.

Users can try connecting their smartphone to a virtual reality device and using it as a joystick. However, this control system is still unstable.

Availability on the market

The most affordable option in the mid-price category is the Gear VR. After a period of intense hype that saw devices being purchased in a matter of hours, the Gear VR is fairly easy to acquire. Similar devices from LG and Google should appear on sale soon.

There are already many games, applications and short videos available for Gear VR that demonstrate the capabilities of the system. Prices for software for Gear VR are slightly higher than the cost of similar products for Android or iOS ($5-$10).

These devices offer the user advanced functionality and convenience at a very affordable price. They work with Android and iOS devices and are compatible with apps that use Google Cardboard technologies.

Advantages and disadvantages of virtual glasses

We can list several useful functions of virtual reality glasses:

1. Interaction with games reaches a whole new level. Moving around the drawn world is perceived as real; the VR helmet allows you to be transported to an ancient era or to another planet and experience new vivid emotions.
2. Reaction speed and innovative thinking develop. Virtual reality forces the player to quickly adapt to a changing environment, and the skill partially transfers into everyday life.
3. VR glasses help relieve stress and take a good break from everyday problems. The user perceives another reality with all his senses and temporarily forgets about everyday worries and troubles.

However, VR glasses also have certain disadvantages. These include:

• possible stress when playing shooters and shooters in the action and horror genres - shooting, explosions and unexpected attacks by monsters are perceived as quite real;
• the risk of getting too carried away with games and movies; you don’t want to take off your virtual glasses, and this can negatively affect your everyday life;
• possible headache and eye fatigue if you use the device too often, especially if the VR helmet does not fit tightly enough and causes at least slight discomfort.

It is not recommended to get too carried away with VR glasses; this can negatively affect your well-being and nervous system.
A disadvantage of modern VR gadgets can be considered their high cost.

Using virtual reality glasses

Virtual reality glasses - what are they? Simple fun? Most gamers think so, but the scope of virtual reality is very wide. Viar technologies are gradually being introduced into all spheres of human life: advertising, education, construction.

Training of specialists

Simulations for future healthcare workers help them learn work skills in practice. This is especially true in the surgical field. Also, the operating principle of virtual glasses is suitable for training military personnel, drivers, and pilots.

Interior design, building construction

Virtual reality is great for creating interior solutions. Many design studios today use VR technologies. The client is invited to independently visit the apartment of his dreams from the future. In the same way, you can superimpose an image of a building onto empty space.

Business, marketing, online trading

The art of sales is always the first to embrace the latest trends. People are starting to learn about virtual reality glasses and how they work. In this regard, companies are increasingly releasing commercials in VR. The advantage of the method is its high degree of convincingness, achieved through a realistic 3D image.

Remote control of objects and devices

The potential of virtual reality devices is limitless. VR helmets are now used to remotely control robots and machines. The distance from which objects can be controlled reaches hundreds of kilometers.

Control drones

Some drones actually support VIA control technology. This function is used in agriculture, as well as other industries. Modern drone models immediately come complete with the necessary VR headset. Such new products are associated with the fourth industrial revolution.

Control of military equipment

AR and VR devices are capable of controlling tanks and unmanned vehicles. Augmented reality is convenient because it can display current equipment indicators and operation goals. Thus, AR glasses are gradually moving from video games to reality.

Virtual reality has found a strong response in society. Today it is being implemented everywhere - from military simulators to sofa advertising. Probably, VR may soon become as commonplace as smartphones.

Development prospects

Most often, virtual reality is used in the gaming industry. Now it is becoming more and more popular and accessible, it is being implemented in:

• training methods - especially in the medical and military industries, drivers and pilots;
• design and construction – the client is given the opportunity to purchase real estate using VR, visit a future house/apartment, create a layout and design virtually;
• business and trade - advertising is perceived brighter and more interesting;
• remote control – cars, household appliances (“smart home”);
• drone control – especially in industrial and commercial areas;
• control of military equipment.

Virtual reality has become firmly entrenched in society. Now it is capturing more and more spheres and areas.
