Virtual reality is now becoming available to almost anyone. It is enough to purchase the appropriate gadget — virtual reality glasses. However, in order not to be disappointed after the purchase, you need to study which smartphones, laptops and PCs are suitable for VR glasses. You should know how they are arranged, what you can watch in them, how to use VR glasses. All these questions will be discussed in the text below.
Device and principle of operation
Virtual reality glasses work by using the effect of stereoscopy. Anyone could notice that when looking at one image with the left and right eyes separately, the picture shifts slightly in space. When both eyes are open, it has a certain position and is displaced by turning the head. Virtual reality glasses are designed in such a way that the same picture is presented to the eyes, but slightly shifted. In other words, one eye sees one part, and the other the second part, and at the same time the pieces of this image intersect. Further, the human brain is included in the process and combines both images, which ultimately gives the 3D effect.
The principle of operation of VR accessories is based on stereoscopy, but for it to start working, it is necessary certain design. In fact, all the work in this case is done by lenses that distort the image from the smartphone display, and in the case of stand-alone helmets or devices for PCs and consoles, two screens are used or one divided into two parts.
In order for the user to change their position in the space of the three-dimensional world, VR accessories Equipped with magnetometer, accelerometer and gyroscope. Each of them performs its own function — tracking the position of the user’s head, tracking the speed of rotation and adjusting the displacement, but in combination they provide a process that does not affect the well-being of a person.
It is interesting! VR technologies first appeared back in the 90s, but then the technology was not so developed. She could not adjust the changes in such a way that the user felt comfortable. The first versions literally rocked the subjects, causing dizziness, nausea and headaches. Today, such side effects are not observed precisely due to the built-in sensors.
VR glasses for smartphones use phone sensors, and in the case of virtual reality helmets that connect to a laptop or game console, they cover the helmet directly, and readings are taken from them special camerasinstalled near the user and PC. Sometimes the readings are simply read from the helmet, it all depends on the specific model.
What can you watch with VR glasses?
Modern VR devices open up great opportunities for the user. You can watch movies, 3D photos, play games or use applications for virtual tours. It is important that the content that the user wants to watch is compatible with VR gadgets.. If we are talking about videos, then they are available in large numbers on YouTube, the user can watch the concert, being directly in the hall or from the stage, look behind the drum set or stand next to the vocalist.
In addition, you can watch movies, in this case the choice is not so great, because the technology itself requires a special method of shooting, which uses many cameras to capture the same scene from different angles and angles. At the moment, one of the movies that are available to watch through in VR is Blade Runner 2049.
Applications and games can be downloaded from the Play Market or the App Store for a smartphone; in the case of a PC, they are sold in online stores or on discs for game consoles.
On a note! Many apps are designed to teach children. For example, they can look at the starry sky, visit the depths of the sea or in an art gallery located on the other side of the world.
At the moment, the amount of VR content is growing exponentially, as the interest of buyers is higher and the technology itself becomes more accessible. For a smartphone, simple glasses can be bought for several thousand rubles. Virtual reality helmets for working with a laptop or computer are still expensive at the moment, but if a few years ago the first models at the start cost under 80 thousand rubles, today their cost is two times lower, and this is for the best options.
There is an opinion among users that you can use virtual reality glasses together with any smartphone on a relatively fresh operating system. In fact, this is not true. First of all, you should understand that glasses can impose their requirements on the smartphone manufacturer. For example, Samsung Gear only works with its own brand devices. But even if there are no restrictions on the manufacturer, there are still a number of conditions that affect the possibility of immersion in 3D. So, for VR glasses, you need a phone that meets the following requirements.
- Sensors. A necessary condition for the full use of glasses is a gyroscope, an accelerometer and a magnetometer. Sometimes you still need a GPS module, but this is rather an exception to the rule, and in most cases it is not necessary.
- Operating system. If the connection is made to an Android phone, then the minimum version for today is 4.0. For Apple — iOS0
- Smartphone stuffing also affects the quality of 3D graphics. In general, starting from 1 GB of RAM, you can use VR, but ideally it should be at least 3 GB. Regarding the processor — the more powerful it is, the better. Excellent options are Snapdragon 660, 710, 835, 845 and similar ones from other manufacturers.
- Smartphone diagonal today is not a decisive criterion, but most of the VR models are designed for 4.7-6 inches. Larger devices may not fit in the case.
On a note! There are no requirements for the type of matrix and its resolution, but the best result will be obtained on Amoled displays with a resolution of FHD.
Which smartphones are suitable for virtual reality glasses is now clear. The list will be very wide, and even devices from 10 thousand will allow you to experience high-quality 3D, but with a PC everything is not so simple.
To connect virtual reality glasses to a computer or laptop, they must have powerful stuffing, namely the chipset, video card, RAM, and also have a certain number of certain connectors. At the moment, there are models of VR helmets that can work with an integrated graphics adapter, but the functionality will be limited to movies and photos. For top helmets, the requirements are currently more stringent.

Important! It should be understood that the HTC Vive and Oculus Rift are currently considered the best helmets and have the most stringent requirements for a computer. Therefore, if it has the right parameters, then other helmet models will be able to interact with it.
To use VR glasses on a smartphone with Android or iOS, no special setup knowledge is required.
- First of all, it is necessary download a compatible app and run it. The screen should split in two — this is normal, as it should be. There is nothing to fear here.
- Now put smartphone into glasses. The methods are different — for some they are attached to a special clip, in other models they are inserted into a special slot or into a compartment with a hinged lid.
- Further, it remains fix goggles on head, rubber holders with the ability to adjust the length are usually used for this. If the accessory has a built-in headset, then a plug from glasses is inserted into the 3.5 jack.
Adjusting VR glasses may include adjusting the focal length and space between the lenses. In this case, the user simply turns the appropriate knobs on the surface of the accessory and adjusts the picture directly for themselves. It is better to buy those models that are equipped with this feature.
If the glasses are not equipped with a regulator, then come to the rescue cardboard app. It will independently determine the model of the accessory and perform the settings, if this does not happen, then you need to provide permission to use the camera.
If a joystick includedit must be connected via Bluetooth.
Important! Most joysticks have a mode switch — Key and Game. For games, you should use the second mode, for control during normal use, you should stop at Key.
You can set up PC glasses only according to the manufacturer’s instructions, since the best models of VR glasses and helmets have their own nuances for calibrating and installing cameras or laser readers. However, there are programs that allow you to synchronize your PC, glasses and smartphone. So, on devices that support VR glasses, you will need to install certain software. According to reviews, the best option is the Trinus VR app for Android and Trinus VR Server for PC. The principle of operation here is as follows: the smartphone duplicates the application from the PC to the helmet and acts as an intermediate link.
- The first stage of setup is installing applications on a laptop and smartphone. After that, it is best to reboot them so that everything works correctly.
- Now we launch the Trinus VR Server application on the PC and choose the method of connecting gadgets. Users note that it is most convenient to connect use USB connection PC and smartphone, since Wi-Fi connection is not always stable, most likely this is a feature of the software.
- Set graphics settings. The latter are individual for different devices, so here everything must be done in accordance with the capabilities of technology.
After completing the above steps, it remains only to start the game.
Advice! It is best to use a gamepad to control. An excellent option is the Xbox joystick, which syncs perfectly with Windows.
