Why do you need a gyroscope and how to find out if it is in the smartphone? Gyroscopes on radio-controlled models.

There is a huge amount of inventions that are characterized by a long and very rich history of use in various devices and devices. Often you can hear the name of something, but not even have the idea what it is intended for. That is how the question arises, what is a gyroscope? It is worth dealing with it.

Basic definition

A gyroscope is a navigation device in which the rapid rotor is used as the main element, fixed in such a way that its axis of rotation is rotated. Two frames of Cardanova suspension provide three degrees of freedom. In the absence of any external influences on the device, the axis of its own rotation rotor retains a constant direction in space. If the moment of external force has an effect on it, which seeks to turn the axis of its own rotation, then it begins its movement not around the direction of the moment, but around the axis that is perpendicular to it.

Features of the device

If we talk about what a gyroscope is, it is worth noting that in a qualitatively balanced and fairly fast rotating device installed on high-entertainment bearings, with small friction there is practically no moment of external forces, so the device can maintain its orientation in the space almost unchanged. Therefore, it is able to indicate the angle of rotation of the base on which it secured. That is how first it was clearly demonstrated by the French physicist J. Fouco. If you restrict the turn of the axis of the special spring, then when installing the device to which the gyroscope performs, the gyroscope will deform the spring until the moment of external force is equalized. In this case, the strength of stretching or compression of the spring will be proportional to the angular velocity of the aircraft. This principle employs an aviation indicator of rotation and many other gyroscopic instruments. Since very small friction is created in the bearings to maintain the rotation of the gyroscope rotor, no energy costs are required. Major, to drive it in movement, as well as to maintain this movement, a small electric motor of low power or a jet of compressed air.

Gyroscope: Application

Most often, this device is used as a sensitive element for indicating gyroscopic instruments, as well as as a rotation angle sensor or an angular velocity for devices operating under automatic control. In some cases, the gyroscope can serve as an energy generator or moment of force.

On the this moment The principle of operation of the gyroscope allows you to actively use it in aviation, shipping and cosmonautics. Almost every sea long-diving ship has a gyrocompass for automatic or manual administration of the vessel, and some are used and gyrostabilizers. The fire artillery fire control system is usually equipped with a plurality of additional gyroscopes that are designed to provide a stable reference system or to measure angular velocities.

If it is clear to you what a gyroscope is, then it should be understood that without it is simply unthinkable automatic control torpedoes. Helicopters and aircraft are also necessarily equipped with these devices in order to provide reliable information about the activities of navigation and stabilization systems. Such devices can be attributed to the aircraftizont, a gyroscopic indicator of rotation and roll, hyftical. If we consider a helicopter with a gyroscope, then this device can serve as an indicating device and as an autopilot sensor. Many aircraft are equipped with gyrostabilized and other equipment - cameras with gyroscopes, horses, navigation visits. In military aviation, gyroscopes are actively used as composite elements In the sights of bombing and air firing.

Application in modern gadgets

So, if we consider what a gyroscope is, it should be noted that this device is actively used not only in the previously indicated areas. Modern smartphones and tablets are equipped with a mass additional features and modules, while some turn out to be very useful, and others can interfere with the comfort of the device, irritating users. One of them is a gyroscope in the phone, that it becomes clear when you enjoy your device. On the one hand, it turns out to be very useful, although on the other - most users prefer simply turn off it.

what is it?

First you need to decide that it is for the device and what functionality it is characterized. So, the gyroscope in the phone is that the item is necessary to determine how the device is oriented in space. In some cases, this sensor can be applied to protect individual elements of the device from falling in the future. In fact, this sensor is designed to determine the change of position, and in the presence of an accelerometer - and acceleration when falling. The information is then transmitted by the gadget computing unit. With a certain software The device makes a decision on how he should react further to the changes that occurred with it.

What else do you need?

So, if with the question what a gyroscope is, everything becomes clear, it remains to find out why it is used in phones. Protection of indoors is not the only task. In combination with a variety of software, a number of different functions lies on it. For example, a smartphone can be used for games in which control is carried out by means of slopes, shaking or turning the instrument. Such management allows you to make games truly fascinating, thanks to which they enjoy in high demand.

It can be noted that the products of the company "EPPL" is equipped with gyroscopes, and they play a very significant role, as the work of many applications is tied to them. Under it specially developed a mode called CoverFlow. There is very a large number of applications operating in this modeHowever, you can stay on several, most clearly demonstrating it. For example, if you use a calculator on the iPhone, then only simple actions will be available in the user portrait, namely: addition, subtraction, division and multiplication. But when you turn the device for 90 degrees everything will change. The calculator is switched to the advanced mode, that is, the engineering in which functions will be available much more.

If you understand how a gyroscope works, it should be noted that its functions can be used to determine their own location on the ground.

You can view the map of the area with the use of GPS navigation on this device, and in this case the card will always turn to the other side where your view is directed. Therefore, if you are standing face, for example, to the river, it will be displayed on the map, and if you turn, the position of the map will change. Thanks to this, terrain orientation is greatly simplified and can become quite useful to people who are enthusiastic active rest.

Problems with a gyroscope in the phone

We can say about the shortcomings inherent in gyroscopes. Very often they are disabled due to the fact that the programs react to a change in the position in space with some intake. For example, if you decide to read, lying on the sofa, from the screen of a smartphone or tablet, then the gyroscope and the program associated with it will change the orientation of the page every time you are rotating or change the posture. This causes a lot of inconvenience, since a very rare device is able to properly interpret the position in space, and the situation is exacerbated due to the progress of the program's reaction.

Modern varieties

The first gyroscopes were mechanical. This type of devices is used now, but with some improvements that make them more useful. At the moment there is a laser gyroscope, which is deprived of the shortcomings inherent in mechanical. And it is such a device that is used in modern technique.

Any modern phone is equipped with several sensors. As a rule, it is, distances, magnetometric sensor, thermal acceleration sensor, and gyroscope (exercise).

All of them belong to the MemS group - microelectromechanical systems. It is not at all necessary that the whole set is present in each smartphone, but in many. Let's try to consider in detail what a gyroscope is in the phone and what it differs from the accelerometer.

The name happened from two ancient Greek words that are translated as a "circle" and "watching".

It is a misconception that the gale is an accelerometer. No, it is not. Their functions, of course, are similar, but the devices are still different. We will analyze why.

Gyro features in the phone

The exercise is a sensor that locks the position of the object in space with respect to three planes, and the accelerometer is a device that measures the projection of the apparent acceleration.

So, if the accelerometer responds in the phone, mainly for turning the image of the display, the exhaust person - for minor movements in any plane.

And of course, if both of these sensors are present in the mobile device, then the sensitivity to the smallest and rapid movements (slopes, turns) is much increased.

What is a gyroscope in the phone is understandable, and why is it needed? The use of the masterroom in the smartphone opened completely new and interesting opportunities before users. And the pioneers were the owners of the iPhone.

For example, simply shaking can be answered by incoming call, flipping pictures or pages e-book, You can change the listened track to the next, pause and run again.

When you shake the iPhone, a menu opens in which you can select the last action or return the last canceled.

Who and how uses a gyroscope in the phone

The main user of this sensor is, of course, gamer. Its presence translates the game process to another quality. You can control not only turns, but also the speed of turns.

Any movement of the hero on the display becomes more accurate, realistic. This sensor is absolutely necessary for racing, shooters, simulators, etc.

It is he who helps to target the gun, turn the car's wheel or driving a helicopter. With it, the penguins are jumping, evil sharks and other animals.

And in general, the presence of this sensor makes the use of a smartphone much more pleasant and more convenient.

Modern smartphones have many sensors and can perform the most different tasks. One of these sensors is called a gyroscope (or exercise) - mysterious, but extremely useful tool. It can be used almost everywhere, and if you competently configure some applications, then thanks to the gyroscope, with a smartphone you can work much faster and more convenient. Let's figure it out, a gyroscope in the phone: what is it for and for what purposes is it needed?

What is gyroscope

The very first gyroscope in humanity is a children's top or yula. Looking at it, you can easily understand the principle of operation of the device under consideration. No matter how the rotating Yula pushes, it always seeks to align their position along the vertical axis.

In the smartphone, the gyroscope is a sensor designed to measure the position of the device in space. This device will help a person to measure the angle of inclination and the speed of moving the gadget, that is, its position. Thanks to the gyroscope, you can determine how the smartphone is moving relative to the earth's surface, and apply this data for their own purposes.

This can be used, for example, for:

• measurement of the speed of the device;
• measurements of the slope of the smartphone on any plane;
• defining the motion of the smartphone from one place to another (not to be confused with GPS);
• determination of the state of rest of the gadget;
• compass functions to determine the side of the light.

Looks like this device as a small chip inside the smartphone. To "touch" will have to fully disassemble the smartphone. It is located approximately in the center of the smartphone to calculate the position correctly. But this chip can be equipped not only in phones, it is still in other household appliances, ships and game consoles.

In the smartphone, the gyroscope is very common and used everywhere. For the first time he appeared back in 2007 in the model of the first iPhone from apple companies. And now it is practically in every one budget smartphone. It is used in applications, games and even the system itself. Here are a couple of examples of how your smartphone operates this sensor:

1. In some applications, you can activate some function by simply turning the smartphone or shaking. For example, in engineering Calculator There is a rotation gadget for 90 degrees, then an additional menu will open.
2. There are programs that allow you to block and unlock your smartphone when you put it on some surface. That is, the sensor fixes that you put the device, and it does not move - in this case there is a lock. As soon as the gyroscope determines that the smartphone was taken into hand and raised - the screen is unlocked.
3. The system has live wallpapers that are beautifully moving depending on how to rotate the screen. This is also the case of this sensor - it is he who recognizes where you turned the smartphone, and gives the team live wallpaper.
4. To view a video in 360 degrees, you can use a gyroscope, just rotate the screen in the desired side and you will show a video fragment on the side.
5. The gyroscope helps the navigation system.
6. In games, especially in races, you can control the turns left or right. It is thanks to the gyroscope that can be used as a smartphone as a car steering wheel.

The most popular direction for the gyroscope is, of course, mobile games. Much more pleasant to play the game when you do not need to drive around the screen to move, but it is enough to tilt the device. So fingers do not interfere on the screen and control is more comfortable. For racing, this gives a feeling of presence on the track, the player immediately feels the road and more smoothly moves at the expense of the light turns of the smartphone.

In some games with the help of a gyroscope, the effect of a shaking chamber is made - as if the picture is behind the smartphone, and it is only a window in that world.

The presence of the sensor under consideration will be for people with professional duties. Thanks to the sensor, you can find out how much the one or another surface lay down - it will be extremely useful to locksmiths, machine cars and other professions. Also, this instrument will help measure the length and distance, will give information about the speed and movement pace.

With a smartphone, equipped with a gyroscope, no longer need a compass, because this sensor is compass. It can in seconds correctly indicate the parties of the world.

YouTube has video with support for 360 ° technology. You can consider all directions of the video using a smartphone without using swipes without touching the screen. If you have this sensor, just appreciate this beauty in this video:

Also used a gyroscope from sports lovers. Due to this wonderful sensor, they will find out how many kilometers have already run without having to connect to the network. More on it can be assigned several tasks in some specialized applications.

What is the gyroscope different from the accelerometer?

It would seem that the gyroscope and accelerometer - the words are synonyms, but not. - It is the younger brother of a gyroscope, which can only determine turns regarding the axis of the smartphone. At the same time, the gyroscope may be, and much more, namely: to learn the movement in space, to determine the parties of the world and the speed of movement. Due to the gyroscope, you can move in space, while the accelerometer determines only the rotations of the gadget at one point and cannot determine the parties of the world.

But why then need an accelerometer if there is a gyroscope? The fact is that these sensors can be used together and under such circumstances the work of the smartphone is optimized several times. Devices equipped with two sensors may much more accurately read information regarding the position and do it faster. But this does not mean that separately these two sensors work badly. For example, only an accelerometer is enough for racing lovers. And for those who use the smartphone as a navigator - only a gyroscope will be useful. But together they will be able to give more accurate information.

In general, the gyroscope is an important element for a phone that has already entered our lives tightly. It is now difficult to imagine the full use of smartphones without this wonderful tool.

Many users studying the characteristics of their smartphone are often found with the presence on the phone of such a device as " gyroscope" What it is, and what are his functions, users often do not know and do not represent, quite often it with it with an accelerometer. In this article, I will try to "shed light" on this problem and will tell you that this is a gyroscope in the phone, what is its functions, what is the difference between the gyroscope and the accelerometer, as well as to find out if there is a gyroscope in the phone.

Gyroscope - This is a special sensor in a smartphone that allows you to determine the position of your phone in space. The gyroscope is taught to react to changing the corners of the body orientation, which it is installed relative to the inertial report system.

The width of such a sensor inside the phone usually does not exceed 10 millimeters, and the height is 5 millimeters.

The prototype of the device with the functions described above was invented back in 1817 by German John Bonenberg, and the term "Gyroscope" himself was introduced into the lexical turnover significantly later - in 1852.

Important! If you do not know what you are in the phone and their destinies, you follow the reading materials on the links.

Gyroscope functions

After we figured out that it is a gyroscope, it is worth lifying the functions that it performs. The main function of the gyroscope on modern smartphones and tablets is the automatic rotation of the image on the screen following the position change mobile device.

In addition, it actively involves various game programs (in particular racing), navigation applications, a variety of service software and so on. For example, the coupling of the smartphone screen can be blocked the screen or turn off the sound, the phone shake will allow you to answer the incoming call or run bluetooth, well, the presence of a gyroscope on the phone allows you to work more accurately with GPS navigation and navigate on the map.

Well, about the benefits of a gyroscope in games and speak. The recent world hit - the game Pokemon Go fully involved the possibility of a gyroscope, allowing the player to catch Pokemon on a familiar area, and Pokemon themselves pretty correctly use the features of the surrounding landscape, read by the phone chamber.

A gyroscope is used and in helmets virtual reality, fixing the turns and tilts of the head of the player, and appropriately adjusting to this computer picture.

The difference between the gyroscope and accelerometer

In the network, it is quite often possible to find opinions about what gyro and accelerometer - This is the same thing that the gyroscope is a more accurate accelerometer and so on like that. In fact, these are two different sensors, and if the accelerometer is usually installed in the default mobile devices, the gyroscope is not always present in smartphones and the tablets of users.

The essence of the differences between these devices lies in their functions. If the exemplary (gyroscope) determines the position of your device in space, the accelerometer measures the acceleration of your device and gives information about its movement (for example, the speed indicator of the movement).

How to enable and disable gyroscope

When analyzing the question of what a gyroscope means, it is also worth mentioning how to enable and disable the gyroscope. In general, De Facto, this sensor works almost always, we can only include and disable the various functions in which it is involved (for example, the coup of the screen of our device).

For example, to use the mentioned twist of the screen, go to the settings of your mobile device, tap them to the "screen", and in the screen settings, use the "Auto-rotor" function.

Accordingly, it is necessary to deactivate it in the same way to turn off this feature.

How to find out if a gyroscope in the phone

Most modern phones have built-in gyroscope sensors. If you, nevertheless, doubt it, is enough to drive into the search string search engine The brand and model of your device, and then read its full specifications.

You can also use the auxiliary programs that provide complete information about the device. Can recommend

The gyroscope is one of many modern sensors, without which it is difficult to introduce the work of the smartphone.

The scope of this sensor in the phone is quite extensive. A full-fledged gyroscope visually resembles Yula inside a few wrap. Due to the dimensions, such a design cannot be installed in a gadget, so it was replaced by a sensor based on a microelectromechanical system.

What is a gyroscope?

A gyroscope in a modern phone is a sensor that allows you to automatically change the orientation of the screen depending on the position of the smartphone.

For the first time, the gyroscope was installed in the iPhone 4, so that the device has gained a new useful functionality. With a sensor, users have the opportunity, for example, overclock the pages and switch tracks in the player shaking the smartphone.

To turn on the sensor on devices from the operating room android system 4.0 Kitkat and higher enough to roll out the notification blinds and activate the screen of the screen of the screen.

Accelerometer and gyroscope

Usually, modern phones Equipped with these sensors in a pair. The principle of their work although it looks like, but not duplicated. Measures the acceleration of the object when moving, while the gyroscope measures the angle of deviation of the apparatus relative to different planes.

Gyro functions in smartphones

Gyro removed game process to a new level. Rotating the device in space, the user can control the car, lead the game duel, search for characters and much more.

If speak about standard applicationsThe most significant advantages of the gyroscope look, for example, in the calculator application. In portrait orientation, the user is available standard actions: addition, subtraction, multiplication and division. Turning a phone for 90 degrees, you can get a large selection of trigonometric functions for all occasions.

Of course, with automatic operation of the sensor, it is much more convenient to watch the video in YouTube and flipped photos. Another sensor can be used to make a building level from the phone - the special application should be downloaded.

In fact, there is no shortcomings of the gyroscope. Of course, there is some discomfort when viewing pictures or reading, when changing human poses and devices are possible unwanted screen orientation changes. Solution Simple - Disable the autoprot in the settings.
