What is a virtual reality headset and what does it come with? Review of the best gadgets for immersing yourself in virtual reality

Even to visit virtual reality using a smartphone, you will need a VR headset. If you want to see a realistic picture, you will need a powerful gaming computer and an advanced VR helmet. Today there are two such helmets: Oculus Rift And HTC Vive. But which one should you choose?

At first glance, the difference between Oculus Rift and HTC Vive is obvious: the first VR headset costs $600, the second – $800. But you are very mistaken if you think that the more expensive headset is better in all respects. Let's compare several parameters and decide which one is worth purchasing.

VR Headset Comparison: Immersion

Put on a VR headset and you will instantly be transported to another world. Wherever you turn your head, you will see and hear things that don't really exist. The main purpose of a virtual reality headset is to make you believe that everything you see is real. So how much can the Oculus Rift and HTC Vive immerse the player in an atmosphere of virtuality?

In terms of visual and audio fidelity, both helmets are similar. They have the same matrix size (2160 by 1200) and the same resolution of the output image (1080 by 1200). The only difference is that you connect your headphones to the Vive, while the Oculus Rift already has them built-in. So overall, virtual worlds look and sound pretty much the same on both VR headsets.

Yes, modern technologies were able to deceive the eyes and ears of a person, you feel your presence in the game. But a game is not a movie; it assumes that the player will move and perform some actions. And this is where Oculus Rift loses. But Vive has sensors that allow you to physically move in virtual worlds and interact with phantom objects.

Therefore, in terms of immersion in virtual reality, the HTC Vive wins.

VR Headset Review: Interaction

So, what can you do in games using a VR headset? Both the Oculus Rift and HTC Vive allow you to tilt your head to get a closer look at what's under your feet. If a virtual cake flies into your face in a game, you can tilt your head and dodge. But for some more significant actions you will need a joystick.

On the HTC Vive, the joystick function is performed by two controllers that need to be held in your hands. When you pick up something in the game, the controller vibrates. Controllers in the virtual world can turn into anything: your disembodied hands, a weapon, a paint brush.

HTC Vive also has sensors that record your movements, so you can move around in virtual worlds while walking around a room in the real world! And to avoid hitting anything, the headset measures the distance from the player to the nearest objects, and if dangerously close, draws the contours of the real world in the game.

Unfortunately, Oculus Rift can't offer anything like that yet. The developers promise to release similar controllers called Oculus Touch in early 2018. Well, then our opinion may change, but at the moment HTC Vive provides better player interaction with the virtual world.

Choosing a VR helmet: ergonomics

Unexpected news: VR headsets are basically uncomfortable! They put pressure on their face and their lenses fog up. In general, a player wearing a VR helmet feels like wearing a diving mask. But when choosing between two evils, we will prefer the more comfortable and ergonomic evil.

In our case it will be Oculus Rift. The design of this virtual reality headset is more compact and simplified than the Vive, and the cable for connecting to a computer is relatively thin. The built-in headphones have flaps, there is internal ventilation to keep the lenses from sweating, and the fit of the headset to the size of the player's head is quite precise. And, most importantly, there is enough space inside the headset so that a visually impaired player can keep their glasses on.

But the Vive headset is more massive and heavy, and a thick cable for connecting to the computer runs down the player's back. The cable is very long, and getting tangled in it is a piece of cake. As a rule, this cord gets tangled underfoot when the player walks in virtual space.

So in terms of ergonomics, Oculus Rift wins.

Buying a VR headset: connection and setup

Of course, first of all, to immerse yourself in virtual reality, you will need a powerful gaming computer. Then you buy and download gigabytes of games. But before you start playing, the VR headset needs to be connected and configured.

With HTC Vive you will have to tinker: in addition to a fair number of cables (three power adapters, two USB chargers, as well as video, USB and sync cables), you need to install bases with sensors in the corners of the room to track movement, and then calibrate them. Every time before playing, you need to launch Steam, switch it to VR mode, turn on the controllers and bases, and make sure the headset is working properly.

The Oculus Rift is easier to handle in this regard: this headset has only two cables and there is no need to launch additional software or recalibrate the headset before starting the game. And you don’t need to turn anything on: Oculus automatically turns on when you put it on.

In this round, the victory goes to the Oculus Rift headset.

Comparing virtual reality helmets: content

Oculus wants to build its own gaming platform and form its own gaming community. You won't find Oculus exclusives on the Vive because Oculus (and the developers) are investing millions into making their gaming "ecosystem" possible.

And therefore, one cannot argue with the fact that real multi-hour games are released on the Oculus Rift, while the Vive content is more like a set of short demos for games. But we will still take a risk and rely on HTC Vive in terms of quantity and quality of content.

Why? It's simple: the Vive headset runs on the Steam platform, which already dominates the online market computer games. Steam has built-in trading instant messages, voice chat, the ability to join friends in the game - in a word, all those little things familiar to the modern player that the Oculus Rift does not have. This is not to mention that through Steam games are purchased and installed in a couple of clicks, and their progress is saved and automatically updated on different devices.

In addition, HTC Vive offers to play with motion controllers, and developers are happy to pick up this idea. They are already making games for this system, and Oculus has not yet even acquired prototypes of such controllers.

Therefore, in terms of content, HTC Vive wins.

Which virtual reality headset should you buy?

For now best helmet for VR immersion, it's the HTC Vive. Yes, it costs $200 more, is less ergonomic, and requires a lot of fiddling to install and configure, but in return you get the experience of being immersed in full-fledged virtual reality, in which you can walk with your feet and do something with your hands. Buy HTC Vive if it's important for you to stay up to date with cutting-edge technology.

True, there is no guarantee yet that HTC Vive will retain the leadership palm after the release of Oculus Touch controllers. Perhaps the new controllers will be much more better than that, which Vive offers (for example, they will be able to recognize gestures).

But to be completely honest, we wouldn't recommend buying either the Oculus Rift or the HTC Vive just yet, at least not for the next year. The fact is that now there is not much content for both VR headsets, and virtual reality technology is only at the initial stage of development. Wait a year - it will come out by this time more games, controllers for the Oculus Rift will appear and it will be clear in which direction the VR gaming industry is moving. And at the same time, a clear leader among VR headsets will be determined.

The Matrix is ​​already here. From today.

Russian launch took place gaming headset from PlayStation. In anticipation of the long-awaited event for geeks, we tried to collect the most important things that travelers to non-existent universes should know.

Why do you need PS VR?

Virtual reality headset - new step in the development of information transmission devices. If successful, VR has a good chance of replacing conventional TVs and monitors.

Virtual helmets, glasses and other devices in this category have been trying to penetrate our daily lives for several years. Knowing the passions of gamers for technological innovations, it is not surprising that today this audience is the most ready for change.

A high-tech innovation could hardly be called intriguing if its essence boiled down only to getting rid of bulky LCD panels. Its main charm lies in its unique experience, which can evoke a mixture of delight and surprise.

From now on, the character depicted on the screen and the player are one. Whether it's a merciless shootout, or a session of meditative contemplation, there are no barriers between you and virtual events.

Just put on the headset, and you are transported from your own living room to distant worlds, seducing you with colors and incredible fantasies.

How does PlayStation VR work?

Thanks to the built-in display and complex system The lenses of the headset create a stereoscopic image that covers, if not all, then a significant part of the view.

Avoiding banal quotes about the role of visual information in forming ideas about the world, it is not difficult to guess how much such technology is superior to the monitors we are used to, even if they are equipped with 3D support.

Our brain willingly believes in an illusion if it is not disturbed by extraneous phenomena, such as low frame rates and flickering noticeable in peripheral vision. To meet these needs, engineers worked diligently on the new product, taking into account the experience of competitors.

PlayStation VR has a single 5.7-inch OLED display. It supports 1920x1080p resolution and covers 100 degrees of view at 120Hz.

Equipped with several sensors, the PlayStation helmet is capable of registering the position of the device in space. This allows you to track your head rotation and gaze direction, eliminating the need to use a mouse or gamepad to control your view.

In order for the sound to match the visible picture, the authors of the device took the trouble to develop a special algorithm. With its help, the device interprets the character's position in a fictional space and creates the necessary volume of sound.

Do I need to buy PS VR accessories?

Despite the assurances of marketers and salespeople, we cannot completely agree with the statement that PS VR is a completed product. Nobody lied when they said that the glasses are ready to use immediately after they are taken out of the box.

Consoles themselves are a category of products freed from the need for additional manipulations with drivers and checking hardware compatibility tables. The maximum that will delay you in the real world is installing a patch.

But speaking of a full-fledged VR experience, buying one helmet is not enough. If you want to digitize yourself down to your fingertips, you'll have to buy a PS Eye camera and Move controllers.

A complete collection of accessories will bring you as close to the virtual experience as possible, making it immersive and realistic. It’s also interesting to play with a regular gamepad, but the experience is still not the same.

Does the headset work with the regular PlayStation 4?

For almost the entire 2013, the PlayStation PR department fed the audience promises of native support for the Full HD format. In reality, not all projects can boast of it.

To achieve a clear picture with a minimum of flaws, software developers go to all sorts of tricks, including rendering technologies with dynamic resolution and lowering the frame rate.

No matter how much Mark Cerny tries to show off the teraflops and iron power of his brainchild, the console quite often faces the problem of drawdowns and lags. Whether this is due to the laziness of the developers or the complexity of the architecture - the fact remains.

The PlayStation 4 Pro is designed to solve this problem - a fresh revision of the PS4 with improved hardware. Not counting support for 4K TVs, new model The console was created with VR in mind.

In addition to a stable frame rate, the firmware should say goodbye to the problem of soapy images inherent in regular version consoles. PS4 Pro should appear in Russia in November, it will cost 34,999 rubles, 500 rubles more expensive than the headset itself.

A PlayStation VR helmet will work with a simple PS4, but if you want to enjoy good image and dynamic personnel changes, it is advisable to wait until November.

What to play with PS VR?

Two years ago, when Sony was just talking about the secret Project Morpheus, the company promised to provide headset support for absolutely all projects released on the platform.

In general, PS VR can be used as a regular TV and even watch Blu-ray movies through a headset. But the full immersive experience beyond the realm of transistors will only happen in games that were designed with VR in mind.

Today's list contains about 80 items, which is no reason to complain about the tiny library. We will launch most of them only a couple of times - on the day of purchase, and to show our guests the electronic wonder.

It’s hardly worth hoping for serious VR support from third-party developers. We will probably play the biggest hits from Rockstar, Bethesda and Bungie as before, using the Dualshock 4 and sitting on the couch.

But thanks for that. In any case, for now we have no fears that the PS VR will gather dust in the closet a month after purchase.

Is there anything better?

The two main rivals to Sony's headset are Oculus Rift and HTC Vive. Both have two built-in displays, achieving a resolution of 2160x1080.

Both are designed to work with computers, which has the added advantage of working with high resolution. Only to work with them you will have to assemble a powerful machine, not counting the price of the glasses themselves.

Priced at $800, the Vive device, developed in collaboration with the notorious Valve studio, comes with motion controllers. Oculus comes with a $600 price tag and is devoid of accessories.

It is worth noting that none of them are officially supported in Russia. You will have to buy headsets either through intermediaries or through foreign stores.

Leaving aside a couple of disadvantages, such as a smaller library of games compared to a PC, PS VR compares favorably with its competitors not only by its low cost ($400), but also by its ease of use, as well as its refresh rate - 120 Hz versus 90 Hz.

By subjective impressions, PS VR sits most comfortably on your head. She puts it on over her glasses without any problems. Vive is next in this regard, Oculus requires the most settings.

In terms of weight, the PS VR turns out to be the heaviest - 610 g versus 555 g for the Vive and 470 for the Oculus. You won’t break your neck with such weight, but tension will appear even in a sitting position, not to mention active entertainment.

All three devices work using wires, so they are on the same level when it comes to portability.

Is it harmful to health?

Despite the serious work that the developers have done in matters of safety for the body, it is impossible to talk about it with complete confidence. More recently, scientists from the UK blamed VR headsets for their negative impact on vision.

According to the conclusion of the medical report, the greatest concern is the use of glasses by children. If in adults the visual organs are already formed, in children screens placed close to the eyes can lead to the development of myopia.

Experts are much more concerned about the impact of a helmet on the brain. Even if you close your eyes to the unfounded hysteria of opponents of progress, who believe that video games will definitely turn you into a degenerate and a murderer, the VR experience can be called a serious load on our main organ.

Consideration should be given to the content you intend to consume, the length of play sessions, and the mental health of individual candidates.

In addition to the brain, other organ systems will also be subject to stress. Not every gamer can afford to be in constant motion.

I’m not trying to joke about obese nerds with a bunch of diseases of the musculoskeletal system, but if we take into account the statistics, fatigue from active entertainment with VR projects sets in after about 20-30 minutes.

What is virtual reality

Virtual reality is an artificial world that can be entered using special technical means.

For what? To get new experiences: to feel like someone else or to find yourself in completely incredible situations.

Now in a wondrous new world You can dive in head first. Not through a monitor, as before, but using VR helmets or VR headsets.

How to get there

Meet this: Samsung Gear VR, one of the most famous virtual reality headsets. Essentially, just a plastic box with grooves for installing a smartphone. Putting this thing on the head, the user sees through the lenses a multiply enlarged phone screen.

This creates the effect of presence. Through the headset, you can view spherical panoramas or 360-degree video by turning your head from side to side. Plus play very simple arcade games with poor graphics.

Why meager? Because VR headsets are not intended for serious entertainment. It's all about power mobile processor. Even if you have the latest glasses Galaxy Note 7 with video card full-fledged computer he can't compare.

Samsung Gear VR

Why do we need VR helmets?

And here the second type of devices for immersion in virtual reality comes to the fore: VR helmets. Here are two of the best today - Oculus Rift and HTC Vive.

Oculus Rift

The gadgets have one thing in common: both connect to computers and cannot work without them. All VR content is stored in PC memory and processed powerful processor and video card, and then transmitted to the VR helmet as to a monitor. There are much more possibilities here than with headsets, and the graphics are much better.

HTC Vive

It turns out that with Oculus Rift the user sits in a chair or watches VR content while standing. With the HTC Vive, everything is much more interesting: there is a small platform on which you can move, and two joysticks with many buttons. With their help, you can take virtual objects and use them. For example, grab a bow and start mercilessly shooting the little men besieging the fortress. King Arthur, we are under attack! From the outside, the process looks very funny.

HTC Vive comes with special joysticks for control.

By the way, have you already guessed that you won’t be able to play your favorite Crysis or any The Witcher with Oculus and HTC VR glasses? All content is “tied” to the manufacturers’ branded stores, and this is the main problem. All virtual reality today consists of photos and videos in 360 degrees, demo applications and a very limited number of special games. The mechanics of them are interesting, especially in the case of the Vive, but overall they are quite simple.

Virtual reality glasses, mobile VR headsets for smartphones (Mobile VR) are a very big business. Google has gone all-in on it, and there are some great VR headsets that also work with Apple iPhone. Premium mobile VR headsets for smartphones, such as the HTC Vive or PlayStation VR, are expensive, but that doesn't mean you can't get in on the VR action for a different price. There are standalone VR headsets on the horizon, but until then, all you need is a cheap headset and a smartphone in your pocket.

Mobile VR applications and games in App Store And Google Play- you simply use the hardware and technology of your smartphone to power the engine and visual effects. They are essentially glorified lenses with lenses, often with a few extra features added.

Mobile VR headset: Samsung Gear VR

If you have samsung phone and you want to use VR, it’s quite possible to spend extra money to get newest Gear VR Solving many problems with previous ones Gear headsets VR, the latest device is now more comfortable, making more options for glasses wearers and including vents to get rid of that annoying screen fog.

Most importantly, there is a lot here entertainment content. Samsung and Oculus are constantly adding more and more content, and it's not just games - there are also short films and TV shows. This is the best you can get at home if the Vive and Rift are too expensive for you.

The device also recently welcomed a controller into the mix that tracks the movement of your hand and has a circular touchpad With touch screen, which allows you to point, drag objects, tilt (which should help minimize motion sickness) and, of course, shoot in games, this accessory costs a little more, but it's without a doubt worth it.

Mobile VR headset: Google Daydream View

The new take on Google Daydream View features a sleeker, more user-friendly design. The VR mobile headset for smartphones comes in two new colors: black and pink, which Google likes to call coral.
There's even a head cover to store the controller. As you can tell, the new Daydream View has a lot of quirks and tricks to make it best experience over his predecessor. The field of view even increased from 90 degrees to 100 degrees. There's even a new heatsink that improves performance during long sessions.

The new headset is compatible with more a large number phones, so if you have a Galaxy S8 or S8+ then you're in luck!

Mobile VR headset: Google Cardboard

The original and most economical, cardboard has a simple three-step assembly procedure, best button controls and support for larger smartphones up to 6 inches. Interestingly, Google has opened up a platform for iOS developers.
Cardboard is an inexpensive mini virtual reality headset that can be built by anyone, but there are many third-party alternatives such as DodoCase.

Actually, quick search on the Internet shows that you can get it for only 300 rubles. Just look for the Cardboard Tools icon. Official mobile VR headsets for smartphones cost a little more.

Mobile VR headset: Merge VR Goggles

Like Google Daydream View, Merge VR Goggles opt for soft material rather than hard plastic, the most affordable VR glasses. Specifically, the glasses are made of soft and flexible foam that is not only extremely comfortable to wear, but will also protect your phone if you're clumsy. They will fit any smartphone from 4 to 7 inches, and are also equipped with adjustable lenses.

So, Merge is extremely light and you don't feel it on your head. Most of the weight you will feel comes from your phone.

Mobile VR headset: Xiaomi Mi VR Play

As we said in our review Xiaomi games Mi VR: "You get what you buy." It's not the company's Daydream headset - that's still out of action - but it's another alternative to other more expensive mobile headsets.

This is not best device but it gets the job done and works with iOS phones and Android. The Mi VR Play is also ridiculously cheap, practically rivaling Cardton's own prices. There's also a newer and more user-friendly Xiaomi Mi VR Play 2, but it's unclear when it will be available outside of China.

Mobile VR headset: Zeiss One Plus

The Zeiss VR one plus model will play ball from any iOS devices or Android between 4.7 and 5.2 inches. It includes a media player for similar photos and videos on YouTube and an AR app for augmented experiences. With open source code For unity3d, SDK means that there is a lot of room for development. If you wear glasses, this is designed to be comfortable to wear with glasses too.

Notable features include a removable head and headband strap that makes contact with your eyes, plus you can clean the optics and the universal tray will support smartphones between 4.7 and 5.5 inches.

The FreeFly VR headset offers a 120-degree field of view and even has its own Bluetooth gaming controller for better control over your VR games, but iPhone VR games don't actually use a controller.

The latest version of FreeFly, called Beyond, combines Crossfire's dual touch triggers. The VR headset is compatible with smartphones from 4.7 to 6.1 inches, allowing you to use all the latest devices.

Mattel's 2nd-gen View-Master VR headset was the first to actually be sold in Apple stores, but has since disappeared (maybe an Apple VR headset could be on your way?). You can still pick it up from other stores.

DLX VR has a redesigned smartphone mount to work with more smartphones and now offers headphone support and improved lenses on the first try. It's all modeled after iconic designs View-Master with a more modern twist for this second edition.

BlitzWolf's latest VR headset takes any smartphone up to 6.3 inches in size, and it's all about comfort. This includes adjusting the pupil distance, because not everyone is built the same - sometimes the eyes come together and sometimes they don't.

It goes further than that by allowing you to adjust individual pupil distance, meaning you can change how far or close the lens is to your individual eye. Thus, it can withstand up to 300 degrees of myopia. In addition, there is good leather upholstery.

It's hard to say who was the founder of virtual reality headsets. They appeared several years ago as a separate branch of the development of virtual reality in general and essentially represent an affordable analogue of virtual reality helmets. The development was spurred by an experiment by Google, which was one of the first to develop a product called Cardboard.

Cardboard is a cardboard case with lenses. According to the developers, such a device can be assembled even at home. At the same time as Cardboard, products from other manufacturers began to appear. At the moment, there is a wide range of varieties of virtual reality headsets on the market, from various economy-class cardboard options to premium ones in plastic cases with high-tech lenses. Developers around the world have shown interest in this market segment. Among the manufacturers of virtual reality headsets there are such giants as corporations and. The openness of the Google Cardboard project to software manufacturers and developers is seriously stimulating the development of this area of ​​virtual reality. Just look at the dynamics of the emergence special applications on Google Play, for which a separate branch has already been allocated.

What is a virtual reality headset?

A virtual reality headset is a design whose main elements are lenses, which is why they are also called virtual reality glasses. Sometimes the concept of “virtual reality helmet” is used, but this is rather erroneous, since VR helmets contain video screens, and a computer is used as the primary source. In our case, the picture comes from a smartphone that is installed in the headset. The image passes through lenses, the main function of which is to convert a flat image into a stereoscopic one. The body of VR glasses is most often made of plastic and does not contain any electronic elements.

What's important in a VR headset?

The most important thing in a virtual reality headset is the lenses, they must be of high quality, then the image will be without distortion and glare. It is worth noting that the larger the screen extension on your smartphone, the smoother and clearer the output image you will get. Manufacturers use different technologies in lenses; they may differ in shape and type of coating. The second point is ergonomics and convenience. Such parameters as the weight of the headset and its correct distribution over the entire head due to the straps, as well as the presence of ventilation channels and comfortable padding. An important factor in the functionality of the headset is the ability to adjust the distance between the lenses, which allows you to customize the headset individually to suit your face type. Some manufacturers solve this problem by increasing the size of the lenses and their special design; this approach does not require individual adjustment of the headset. Some manufacturers equip headsets with the ability to adjust the focal length, this allows people with myopia or farsightedness to use it without regular glasses. Adjusting the focal length means increasing the distance between the lenses and the smartphone, and this affects the viewing angle, so it is recommended to use contact lenses. There are headsets whose design allows for comfortable use with regular glasses. The viewing angle in various virtual reality headsets ranges from 50 to 110 degrees and depends both on the design of the lenses and on the diagonal of the smartphone. The larger the diagonal of the smartphone screen, the greater the viewing angle.

Which smartphone can be used with virtual reality headsets?

Each headset is designed for a specific range of smartphone screen sizes. In other words, the headset is selected for a specific screen size. VR headsets on average cover a range of 3.5 to 6 inches. There are headsets for small tablets, for example. Required condition For full use of virtual reality glasses, the presence of an accelerometer and gyroscope in the smartphone. As noted above, the expansion of the screen of your device also has a fairly strong influence: the higher, the better.

How to use virtual reality glasses?

First, you need to download an application that supports virtual reality mode. Many eyewear manufacturers are also developers themselves. various programs and games. At the moment, there is a lot of relevant content: from relaxing flights, roller coasters to programs for working with 3D images, as well as games.

After launching the downloaded application, the smartphone must be placed in the headset so that the screen demarcation line is strictly in the middle of the headset. Then we put the headset on the head, after making sure that the smartphone is securely fastened. The headset should not pull forward or put pressure on the bridge of the nose; the weight should be evenly distributed over the entire head. If necessary, we adjust the focal and interlens distance.

Control in VR applications is carried out by synchronizing the movement of the head and the image on the smartphone screen, using the accelerometer and gyroscope of the smartphone. An action can be performed by fixating your gaze (for example, on a menu item) for a few seconds. You can also control the controller, but their use is quite limited, in particular due to the closed nature of some mobile phones. operating systems to connect to them external devices input. Google developers approached the issue creatively. They used a neodymium magnet attached to the headset body as a control element. When the magnet moves slightly, the smartphone magnetometer detects the change magnetic field, based on this running application produces some action. Nowadays they also use a built-in button in the body of VR glasses, which simulates pressing the screen.
