About 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 managed to become obsolete. Manufacturers are adding new features to their models, one of which is the gyroscope in the phone. What is it, what is it for, how is it used?
Gyroscope and accelerometer
Many people often confuse these two concepts. Let's figure it out.
An accelerometer, or G-sensor, is a device that monitors a change in the device’s position relative to its axis — for example, turns left and right, toward and away from you.
The gyroscope in the phone allows you to register not only these actions, but also any movements of the device in space, as well as record the speed of movement. Therefore, it can be considered an improved accelerometer.
The principle of operation of the gyroscope
The device is a disk that is mounted on two moving frames. It spins fast. When changing the position of these frames, the disk does not move. If rotation is constantly maintained, for example, by means of an electric motor, then it is possible to accurately determine the position of the object on which the gyroscope is mounted. This can be used to determine the cardinal points.
Application options
Back in the nineteenth century, the gyroscope was used by the naval forces and civilian courts, since with it it was possible to most accurately determine the cardinal points. He also found his application in aviation and rocketry.

In iPhone, the design of the device is slightly different from the classical one, since it is based on a microelectromechanical sensor. The principle of action remains the same.
The gyroscope in the phone has a very large scope. Of course, first of all, these are various games that use this technology. The most popular among them are racing simulators and shooters. For example: in shooters, the so-called “augmented reality” is used - shots are fired by pressing, and in order to aim, you need to change the position of the smartphone - the camera in the game will move in exactly the same way.
In addition to the gaming industry, the gyroscope is used in a variety of software. With it, access to various functions becomes much more convenient. For example, on some operating systems, a Bluetooth update occurs when the device is shaken. This technology is also used in a number of specific applications used to measure the angle of inclination (level).
The mobile industry has been growing faster and faster lately. More recently, the gyroscope in the phone was a fashionable novelty, and now it is used everywhere and is considered a familiar part of any smartphone. Perhaps, in just a few years, a new generation of devices will appear that allows you to project an image on any point in space, because science is moving forward with leaps and bounds. In the meantime, we can only speculate on this subject and look for ways to apply those technologies that have already been invented.
