Ten years ago, a phone with Internet connectivity, infrared or Bluetooth technology was something out of the ordinary. Now all these functions have become familiar, and some of them have even become obsolete. Manufacturers add new features to their models, one of which is a gyroscope in the phone. What is it, what is it for, how is it used?
Gyroscope and accelerometer
Many people often confuse the two. Let's figure it out.
Accelerometer, or G-sensor - a device that tracks changes in the position of the device relative to its axis - for example, turns left and right, towards itself and away from itself.
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 fix the speed of movement. Therefore, we can consider it an improved accelerometer.
The principle of the gyroscope
The device is a disk, which is fixed on two movable frames. It spins fast. When you change the position of these frames, the disk does not budge. If you constantly maintain rotation, for example, with the help of an electric motor, then you can accurately determine the position of the object on which the gyroscope is installed. This can also be used to determine cardinal directions.
Applications
Even in the nineteenth century, the gyroscope was used by navies and civilian ships, as it was possible to determine the cardinal points most accurately with it. It has also found its 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 using this technology. The most popular among them are racing simulators and shooters. For example: shooters use the so-called "augmented reality" - 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 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, shaking the device causesBluetooth update. 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 growing faster and faster lately. Until 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 allow you to project an image to any point in space, because science is moving forward by leaps and bounds. In the meantime, we can only speculate about this and look for ways to apply those technologies that have already been invented.
