Why do you need a gyro in your phone?

Ten years ago, a phone with an Internet connection, an infrared port or Bluetooth technology was something unusual. Now all these functions have become familiar, and some of them even have become obsolete. Manufacturers add new features to their models, one of which is the gyro in the phone. What is it like, what is it used for, how it is applied?

Gyroscope and accelerometer

Many people often confuse these two concepts. Let's figure it out.

Accelerometer, or G-sensor - a device that tracks the change in position of the device relative to its axis - for example, turns left-right, on itself and from itself.

The gyro in the phone allows you to register not only these actions, but also any movement of the device in space, and also to fix the speed of movement. Therefore, we can consider it an improved accelerometer.

The principle of the gyro

The device is a disk that is fixed on two moving frames. It rotates quickly. If you change the position of these frames, the disc does not move. If you constantly maintain rotation, for example, using an electric motor, you can accurately determine the position of the object on which the gyroscope is mounted. This can be used to determine the sides of the world.

Applications

As early as the nineteenth century, the gyroscope was used by naval forces and civilian ships, since with the help of it it was possible to most accurately determine the sides of the world. He also found its use in aviation and rocket technology.

In Aiphon, the design of the device differs slightly from the classical one, because it is based on a microelectromechanical sensor. The principle of action remains the same.

The gyro in the phone has a very large scope. Of course, first of all, this is a variety of games that use this technology. The most popular among them are racing simulators and shooters. For example: shooters use the so-called "augmented reality" - shots are produced by pressing, and in order to aim, you need to change the position of the smartphone - the camera in the game will move in the same way.

In addition to the gaming industry, the gyro is used in a variety of software. With its help access to various functions becomes much more convenient. For example, on some operating systems, when the device is shaken, the Bluetooth update is performed. This technology is also used in a number of specific applications that serve to measure the angle of inclination (level).

The mobile industry has been developing more and more rapidly. More recently, the gyro in the phone has been a fashionable novelty, and now it is used everywhere and is considered a familiar detail of any smartphone. Perhaps in a few years there will be a new generation of devices that allow you to project an image to any point of space, because science is moving forward with leaps and bounds. In the meantime, we can only speculate on this and look for ways to use those technologies that are already invented.
