What is a gyroscope on the smartphone. In which phones there is a gyroscope and why it is needed. Gyro functions in smartphones

For some time, it turned out that the gyroscope is a very important sensor. And it is very sad that about his absence, the manufacturers of smartphones modestly silent on their presentations. Fortunately, you can learn about the presence or absence of a gyro as before buying a device and after. How to do it - told in today's article.

But first let's figure it out with what exactly a gyroscope. Also, we will try to find out if it is considered as an important item. And only after that we will tell you about how to check it out.

A full-fledged gyroscope is similar to Yula or Tip. It possesses a stand, a rotor disc, hairpin and several hoops. Its design is designed in such a way that the disc is always in the same position, for which you should thank the force of gravity.

In the smartphone it is impossible to install a classic gyroscope, as it has too large sizes. Therefore, instead, a special sensor is used, built on the basis of a microelectromechanical system. Its width varies from 5 to 10 mm, and the height does not exceed 5 mm. However, such dimensions seem to some of the manufacturers of smartphones too large, in connection with which they often refuse to install a gyroscope.

Where is the gyroscope?

This sensor is an enhanced version of the accelerometer. With it, the operating system not only learns about moving and rotating the device, but can accurately monitor all these actions. If the accelerometer is a kind building levelThe gyroscope increases the accuracy of the readings of this sensor at times.

If you want to purchase for Android in the future, a gyroscope is obliged to be present in your device. This sensor will track the turns of your head, directing a virtual look exactly to the side where your real eyes are directed. Also, the gyroscope on the android helps in viewing the starry sky. If you use the appropriate application, it will understand which direction the camera is directed, showing the names visible in this moment Constellations

And this sensor is used in games with. The most striking example is Pokemon Go. If there is no gyroscope in the smartphone, then pocket monsters will jump over virtual grass. If the sensor is present, then the animals will move to the present world, the visible region of which falls in the view of the built-in camera.

How to find out if there is a gyroscope in a smartphone or tablet

There are several ways to learn about whether a gyroscope is present in your device. The most banal is to go to the official website of the manufacturer to familiarize yourself with the technical characteristics of the gadget. Specifically, the gyroscope must be sought in the list of sensors. But we are not looking for light paths? Therefore, go to other ways.

If youtube client is installed on your smartphone or tablet, then open it and enter a request to the search string " 360 video" Run the show of any of the results issued. If you can give a virtual chamber with the help of smartphone turns, the gyroscope is present and successfully functions. If you can turn the look only with your finger, then the sensor is in the composition of the device.

Another way is to use the application. Antutu Benchmark. . You need to download it, install and run. In the tab " Infa»You will find all the technical specifications of your device. Including you will see the name of the built-in gyroscope. Or discover that he " Not supported"(That is, it is simply no).

Instead of Antutu, you can install a more specialized utility. We are talking about SENSOR SENSE. . It displays readings from all sensor built into smartphone. If there is no gyroscope in the list, then it is not embedded in the gadget. This can be said in the event that the data from this sensor does not change when the apparatus is rotated in the hands.

How to enable gyroscope on android?

This element of the smartphone works on an ongoing basis. It cannot be enabled or disabled. If you think about the screen rotation at this moment, the accelerometer is responsible for it. And this function can really turn off. To do this, make the following actions:

Step 1. Go to the System Settings section.

Step 2.. Go to subsection " Screen».

Step 3.. Here you can easily find the item responsible for the actions of the device when it turns. Change its value to the desired one.

On smartphones with an urgent version Android You can control the option of auto rotting screen through the notifications panel. Depending on the device model, this parameter may be called differently.

On the case of some old gadgets (mainly on tablet computers) You can detect a separate switch. It blocks the screen rotation, regardless of the settings.

Is it possible to set up a gyroscope?

As already mentioned above, the gyroscope is a completely independent sensor, it is impossible to intervene in any way. If the accelerometer can be calibrated, then with the gyroscope no such actions cannot be performed. If he is not at all, then you will have to buy for augmented or virtual reality new phone.

Gyroscopes in phones are used over the past five years. Today, no device does not do without them. But still many people do not know what it is.

If, when creating a phone, the initial idea was to be able to communicate at a distance, due to the development of modern technologies, this is a full-fledged multifunctional device.

Since the global market always holds a great competition between brands, companies seek to show new solutions to their target audience, which are beneficial from other manufacturers. It was the competition that the gyroscope appeared in smartphones.

It is thanks to him that the devices have become more functional, won good feedback from owners. If most recently, the gyroscopes were considered an inquiry element of the device, today target audience It is difficult to surprise their presence. And despite the fact that some consider gyroscope useful element Phone systems, the rest are preferred to disconnect it.

What it is?

A gyroscope is a special chip (in a smartphone), which analyzes the position of the object in space and determines the angles of its placement. Most. simple example The standard gyroscope is Yula - a game designed specifically for children. For the first time, the gyroscope was represented by the public by the German astronomer and mathematician I. Bonenberger.

In some scientific works, there is also information that in fact the device invented for three years earlier. Games are actively used in large numbers of science and technology, including aviation, shipping, cosmonautics. They are installed in household appliances, and, of course, modern smartphones.

Gyro and accelerometer - fundamentally different things

In society, for some reason, the idea was formed that the accelerometer and gyroscope are identical devices, which, accordingly, are intended to perform similar functions. In fact, this is not so. Mounted in a smartphone to track its turn in space. Games are responsible for a much larger list of tasks:

moving the device in space;
determination of the side of the world;
speed of movement in space;
other functions.

In total, the functionality is very similar, so the exemplary itself is a significantly upgraded accelerometer produced as a separate device. If the accelerometer registers the display of the display, the gyroscopes make it possible to determine the movement in three planes. Some applications actively use an integrated microchip to solve internal tasks.

The main functions of the gyroscope in modern smartphones

Thanks to the use of exercises in smartphones, manufacturers made it possible to take advantage of new features. Regardless of which microchip is installed in which the device is installed, the owner will certainly notice the functionality.

For example, earlier in order to respond to an important call, it was necessary to press the button or touch the screen. Now, just shifting the phone, you can start a conversation. In addition, the gyroscope makes it possible to watch photos, interesting images, turn the page in the e-book. In the audio players, you have the opportunity to choose another song, without touching any buttons.

The exhaustacles are incredibly comfortable in calculators. During portrait use, it is possible to cope with the minimum number of functions - multiply, divide, subtract or fold.

If the owner turns the phone to 90 degrees, will receive a number additional features. In fact, the real engineering calculator will appear before him. And most importantly - you do not need to spend time on the search and selection the desired function In the settings menu, the system independently determines when it is necessary to switch to the engineering version, and when - return back to the usual one.

It may seem that the gyroscope is only responsible for performing conventional functions. In fact, this is not so. Developers software Also paid attention to the possibilities of the exhaustacles.

Some oS Provide the ability to re-search for devices. Microchips give the user the ability to use specific programs by means of which the level and angle of the object is determined. Therefore, if you see a builder who measures the angle of placement of certain objects of the house with the help of an iPhone, should not be surprised.

Gyros are very convenient if the owner of the smartphone needs to determine the terrain in which there is a person. You may seem that only the GPS sensor is responsible for such a function, but in fact, it is not.

Now independently calculates the current coordinates of the location, and the gyroscope determines the direction in which the person will turn in real time. For example, if you are in an open area where there are no roads, but you need to get to the nearest settlement, it is enough to turn face to him - and you can see where you can come, if you constantly walk straight. On the contrary, turning back to the desired settlement, you will notice it.

The presence of such assistants makes orientation on an unfamiliar area much easier. Thus, the existence is an indispensable element of the smartphone used by people who like active views of the rest.

Naturally, it does not work out without minuses. Some owners of phones where there is a gyroscope, prefer to turn off it. For example, some applications can slowly respond to changes in the current position in space. In addition, if you are lying reading a book, turning onto the side, the Gedressor will immediately indicate the program on the need to change the orientation of the page. As a result, you may encounter a number of inconvenience.

How and who uses a gyroscope most often?

Practice shows that gamers involve the most common gyroscope. The presence of such a microchip in the smartphone significantly changes the principle of the game. The picture is better. So, for example, before you need to press the screen button to specify the direction of rotation of the vehicle.

Now it is enough to turn the smartphone to the side so that the car goes to the specified side. Moreover, the intensity of rotation depends on the corner of the phone. For a steep entry, it will have to turn the device for 60-70 degrees.

In shooters, the use of exhaustacles contributes to the rapid guidance on the enemy target. Not bypass the use of gyroscope and simulators developers.

The second category of users in popularity are representatives of complex professions in which limit accuracy is required. For example, some autoslers can determine the correctness of the installation of the details, just attaching the phone to them. Builders check the mechanism of supporting structures - information about the degree of location is displayed directly on the screen.

conclusions

A gyroscope is a complex device, without any modern smartphone. Its invention and the introduction into mobile devices made it possible to significantly expand functionality. The phone where there is a private exercise machine, can be used not only to make calls, but also determining the corners of objects, the current direction of the object in space and so on. Even for acceptance incoming challenge It is easy to shake your phone and start a dialog, without pressing any buttons without touching the screen.

Manufacturers are constantly improving the design of gyroscopes. Therefore, modern models do not require so much energy as before. Even if you do not use a gyroscope, do not turn it off, but provided that it does not interfere.

Otherwise (for example, when reading e-book Lying on the sofa) it will still have to deactivate. Without a gyroscope, we could not fully navigate in the conditions of stay on an unfamiliar territory. The gale is rightfully considered one of the most important elements of modern telephones and tablets that increase the amount useful features.

Many have heard about the gyroscope in the phone - what it is interesting, perhaps, only to those users of the gadget, which in the technical characteristics noticed an unfamiliar name. In fact, we use the functions of this microprot, quite often. He is able to publish us at the moment of the lack of the necessary construction tool, indicate us the direction of movement when it is necessary and cope with various, even more complex tasks.

What is the gyroscope in the helicopter?

High-tech devices are widely used in the military-technical equipment of the army. For example, a gyroscope is an important component of the helicopter navigation system. In helicopters, gyroscopic devices are installed on high-quality bearings that do not allow external factors to affect its axis. So it is capable display surface inclination levelto which attached.

When the helicopter enters the rotation, the device presses on the appropriate spring, located under its horizontal base until the crew lines the machine along the vertical axis. Moreover, the pressure of the pressure on the spring is directly proportional to the angular velocity of the helicopter.

Another important function is the stabilization of the helicopter at the time of swinging or driving its tail. Gyroscope:

Determines rocking;
Gives a signal to screw blades;
The blades in turn begin to work in the prevention mode of the machine's spinning.

So the helicopter remains in stable equilibrium and does not depend on air flows or other external factors.

In this video, the physicist Arkady Regionv will show the principle of operation of a large gyrocompass:

Where else use the device?

The gyroscope is very important to aircraft. Its work is studied in detail by the pilots, however, we, simple passengers, it is clear that in the sky the aircraft is focused precisely thanks to this device.

With it, it is performed:

Autopilot work;
Air maneuvering;
Take off and landing.

All this is due to the operation of the gyroscope.

In submarines, the device allows you to determine:

Vessel rate;
Equilibrium or body balance.

Also, such devices are used in astronautics, where to navigate on visual and tactile sensations is impossible.

Great place of the device in robotics. Thanks to its functions, changes in the space in the space of various items, such as the head or body of the robot, can be monitored. Is the main and most an important device in a gyroscuter.

Thus, the gyroscope is an extremely important subject for high-tech industries, the military-industrial complex and the household life of each person. He makes life much easier and makes it more interesting, and for science is the most valuable navigation device.

Gyro: How does the device work?

Modern gadgets are equipped with a lot of different useful features. One of these new products is a gyroscope. It was first used in Apple phones.

This is a small chip inside the smartphone, the essence of which is:

In determining the location of the smartphone in space;
Calculation of cornershorizon.

Thus, many phone functions are directly dependent on the gyroscope:

Direction and speed in the navigator;
Automatic screen transition to horizontal or vertical position;
Games in the phone, where the gyroscope is used as a steering wheel;
The answer to the call or switch different functions by shaking the phone.

Also, the device can act as an appliance measuring angle of inclination, for example, a well-known level. It is necessary in everyday life, and in the construction profession.

All this is the help of the most embellished chip. Today, almost all phones are equipped with such a sensor. You can see this by contacting technical characteristics Gadget or installing a program that allows you to determine all the sensors built into the phone.

The difference between the gyroscope from the accelerometer

Many confuse these two devices, calling them to devices with the same functionality, but different names, however such arguments are erroneous. The principle of action of these devices varies a little:

Accelerometer determines the angle of acceleration relative to the earth, whereas his colleague is the angle of its position;
Accelerometer It has the ability to measure duration movements, and the gyroscope - no;
The accelerometer has the ability to make signals when passing a certain distance;
A gyroscope can define the parties of the light, the accelerometer - no.

Thus, both of these devices perfectly complement each other and are often used in tandem on various devices.

Gyro device

The gyroscope device was invented in the 19th century. Its work is to rotate solid bodies at high speed around the axis. The simplest and most visual example of the unit is a simple toy Yula. When we spin it, she rotates around the axis to those while the external forces do not begin to work on it.

The gyroscope in turn is not subject to such an impact and maintains stability due to much more rotation than yula. Thus, you can rotate the device as you like, but its axis will remain invariably vertical.

The very first gyroscope was mechanical, but further, with the development of science, it became laser and optical. In the electromechanic today, such devices are used in the form of microelectromechanical sensors. That is how it fits in a telephone, a complex navigation system of ships, airplanes and helicopters.

Thus, in the modern world, people live, as they are called high speeds. However, to simplify and increase the quality of life in household source, more and more devices are included, which were previously used only for high technologies. One such example is a gyroscope in the phone. What kind of device, the captains of ships and submarines, pilots and astronauts have long known. IN modern gadget Such a device appeared relatively recently, but it has already been firmly fixed among important and useful functions.

Video about the principle of operation of devices for orientation in space

In this video, Roman Lodin will tell, with which the gyroscope and accelerometer manages to determine their location and what is the difference between these two instruments:

Mobile phones are more difficult every year. To recalculate the number of all sensors embedded in modern smartphones may not have enough fingers of both hands. A gyroscope in the phone - what is the sensor, how it works, what is your use, is it possible to turn off this device? These questions will be discussed for those who want to understand well in their smartphone.

Yula, she is a top - a famous toy. It preserves stability at one point of the support with a quick rotation. This uncomplicated device is the simplest example of a gyroscope - a device that responds to changes in the corners of the body orientation in which it is installed in three planes. The term first used the French physicist and mathematician Jean Fouco.

Gyroscopes are classified by the number of degrees of freedom and on the principle of action (mechanical and optical). Vibrating exercises, subspecies mechanical, are widely used in mobile devices. The use of GPS navigation pushed the initial function of gyroscopes into the framework - assistance in the orientation on the ground, but this technology is still indispensable in modern phone models.

Difference from accelerometer

On modern mobile gadgets, both of these instruments are often installed. The key difference between the gyroscope from the accelerometer and other sensors is in the principle of operation of these devices. The first defines its own angle of inclination relative to the Earth, and the second is able to measure the linear acceleration. The advantage of the accelerometer - the knowledge of acceleration allows you to accurately calculate the distance to which the device was moved.

In practice, both instruments can be replaced and complement each other. In fact, both, and that only register the position relative to the earth's surface. Like a gyroscope, the accelerometer can transmit information about the acceleration of the smartphone to which it is installed. Both sensors are used; They interact well. The table is fixed key features devices.

Principle of work

Simple words, a gyroscope is a top, quickly rotating around the vertical axis, fixed on the frame, which is capable of turning around the horizontal axis, and is fixed on another frame that turns around the third axis. No matter how we turn the top, it always has the opportunity to be in a vertical position. Sensors remove the signal as a wolf oriented relative to the frames, and the processor receives information and reads with high accuracy, as the frame in this case should be arranged relative to the gravity force.

What is a gyroscope in the smartphone

Modern mobile devices for the most part are equipped with gyroscopes. They are also called exercises. This element of the smartphone works on a permanent basis, autonomously, does not require calibration. This device does not need to be turned on, but in some phones there is a function of a shutdown in order to save energy. It is performed in the form of a microelectromechanical scheme located under the enclosure of the smartphone.

What is it needed for

Implementation of the system of living solders in mobile devices significantly expanded their functionality and added new way Device management. For example, simply shaking the phone will allow you to answer incoming call. Changing the orientation of the screen using the slopes of the smartphone is also implemented due to the existence; This device provides chamber stabilization. In the application "Calculator", a simple screen rotation of 90 degrees opens additional functions programs.

The exercise is very simplified using the maps built into the smartphone. If a person turns his device "face" to, say, a specific street, it will be displayed on the map with high accuracy. Good smartphone With a gyroscope provides a couple of interesting opportunities for mobile gemina. The virtual car management becomes incredibly realistic when the machines are used for driving the machine. In the technologies of virtual reality, the heads of the head are tracked with the help of exerticators.

How the gyroscopic sensor works

There are two masses moving in opposite directions in the gym. When the angular velocity appears, the coriolis force acts on the mass, directed perpendicular to their movement. There is a displacement of mass by magnitude proportional to the applied speed. The distance between movable and fixed electrodes changes, which leads to a change in the capacitance of the capacitor and the voltage on its plates, and this is already an electrical signal. Such electronic signals are recognized by the exercise.

How to find out if there is a gyroscope in a smartphone

A simple way is to familiarize yourself with the characteristics of the device on the manufacturer's official website. If the exhaustacle is available - this will definitely be indicated. Some manufacturers are silent about whether there is a gyroscope on the phone, not wanting to spend place on it. They can be understood - everyone is still striving to make the phone easier and thinner. In such cases, third-party applications will help.

YouTube has a whole section of the video that can be rotated by 360 degrees. If you are supported by the ability to control such a video through the rotations of the smartphone, then the gyroscope works. You can still install the Antutu Benchmark application that performs the full diagnosis of your device. There you will find a string about the presence or absence of a gyroscope.

What phones there is a gyroscope

The first smartphone in which the Gedressor was installed is the iPhone 4. Buyers had a positively reacted to such innovation and since then telephones with a gyroscope began to fill the market. All subsequent versions apple smartphones were equipped with exercises. The owners of android devices in this regard are a bit more difficult, the benefit of the presence of the sensor can ask the consultant before buying, or check it yourself. The gyroscope in the phone is an important bonus.

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.

What is gyroscope

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 gaming 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 and in the helmets of virtual reality, fixing the turns and tilting of the player's head, 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. You can recommend ANTUTU BENCHMARK or SENSOR SENSE - they will help you determine the presence or absence of a gyroscope on your device.

Conclusion

When analyzing what a gyroscope is in mobile phone It should first indicate active use this device In modern smartphones and tablets. Many mobile games are not idle without a gyroscope, it is actively used in GPS navigation, and just with the usual work of the smartphone, it can make interaction with the last more easy and convenient. Even the Great Steve Jobs actively "lobbying" the use of a gyroscope on the presentation of the fourth iPhone. And see not in vain.
