🕹 glasses of virtual reality: the nuances of selection, review of models

Appointment of virtual reality glasses

Although the points assigned more and more opportunities, for example, some types of interactive learning and Augmented Reality, in the first place they are still designed to be fun. Basically, this game and view a specially filmed for this format clips.

The device and principle of operation

Depending on the implementation, points can be of a different configuration. Some can be used only on the side of the display, for example - for a smartphone, while others have their own display and connect to your PC or console, if not self-contained glasses with their equipment and software.

In any case, VR glasses are glasses with it the ability to mount them on the head. Inside, depending on the complexity of the gadget can be either a set of lenses for both eyes, or a total system of lenses and two or one display. of volume effect is achieved due to the fact that each eye appear slightly different image. This is accomplished by content creation or shooting with two adjacent chambers being. That is about the same as if the removable process we have seen with our own eyes.

To determine the location of sensors in the present glasses. Gyroscope and accelerometer - usually a minimum set of them. With their help monitored rotation or tilting of the head and, accordingly, adjusts and content that is rotated or tilted in the same direction.

The basic operational characteristics depending on the image source

Image sources can be two: either its own screen or the lens, projecting a video from your smartphone. Therefore, the characteristics are different by virtue of design features.

Smartphone

This is the simplest and most affordable form of points. They are a frame with a compartment to accommodate a smartphone. With special lenses content transmitted to the user. Moreover, this content must be prepared in advance or generated on the fly by the device so that both eyes had on the appropriate video. In these types of glasses all the basic characteristics are determined only by the characteristics of the smartphone. That is, the diagonal and resolution depend on the smartphone screen. Nevertheless, they have parameters such as viewing angle and compatibility with various mobile diagonals.

Built-in display

Points with their own, self-contained display are usually more expensive and have a greater number of significant features. Since this is a separate display, and the characteristics are mainly relevant - resolution, screen type, frequency of updates, the viewing angle. There is also present a set of different sensors - an accelerometer, a gyroscope, a proximity sensor. They guarantee that the head positioning rotating video will be in accordance with the user's actions.

Additional features and capabilities

Now it is necessary to tell a little more about the features and functionality of virtual reality glasses. Modern glasses just crammed full of a variety of sensors, lenses, and other interesting feature.

Accelerometer and gyroscope

Accelerometer and gyroscope glasses virtual reality, as with any smartphone, are responsible for the position of the device. The accelerometer can now be found in any smartphone. It measures proper acceleration, and use it to determine where and how the smartphone has been moved - sharply up or down, or turned aside. Gyro slightly different capabilities: it measures the angle of inclination with respect to the earth's surface. Together, these two electronic sensors and stacked together image displacement, tilt and position in space. Points may be supplemented by a magnetic compass, which determines the direction of user's eyes. This is also to some extent complements the control and immersion in the virtual world.

Setting up the lenses and inter-pupillary distance

Interpupillary distance - it is, in fact, the distance between the lenses. To configure each type of points can have their own built-in calibration mechanisms. Most often it is just spinning handles on the sides of the device. In addition to versions for smartphone inter-pupillary distance can also adjust the distance to the smartphone. In general, for each individual device to better understand the instructions before using it.

Proximity sensor and magnetic button

Proximity Sensor with glasses of virtual reality plays the role of a certain switch, that is, in a state of wearing the glasses work, but when removed - no. Thus, energy saving is achieved.

Magnetic button - it's just a small element that is responsible for managing events in games or other types of content a virtual reality glasses. Usually it is situated on the outside and pressed at sends smartphone magnetic pulse, which reacts in a certain way.

How to choose a virtual reality glasses

All points can be divided into 3 broad categories: Smartphone, PC and consoles. Each type is selected depending on the field of use and the desired result by the user.

Points may differ affordable diagonal, which should be compatible with your smartphone, and you should pay look for when buying on the viewing angle: the higher it is, the more content you can contain in scope.

PC

Versions for PC points is much more complex structurally and technically, and therefore have a large spread in performance. These models have their own display, which means - you need to pay attention to its parameters. For example, on the refresh rate and resolution. The higher these numbers, the better. A set of sensors is also better to have a wide - at least an accelerometer, gyroscope and proximity sensor.

for consoles

Technically points for consoles is almost no different from the PC version. When you select should pay attention to the presence of sensors, screen resolution, its frequency and type. Cantilever points in value are at the middle level between the universal and PC versions.

leading manufacturers

As usual, with the emergence of new trends that are becoming popular, to produce fashionable products are becoming - from small to large. It is the same with the market of virtual reality.
