What is a gyroscope on your phone?

If you are using a vivo mobile phone, the gyroscope is also called an angular velocity sensor, which can make a good measurement of the rotation and deflection of the mobile phone, so as to operate the mobile phone accordingly. Gyroscopes are applied to games, camera stabilization, navigation, and more. Models equipped with gyroscopes have this function enabled by default.

Gyroscope app on your phone.

1: Motion-sensitive GUI: Through a small tilt, deflect the phone, realize the selection of menus, directories and the execution of operations.

For example, tilt the phone back and forth to realize the scrolling up and down of address book entries; Tilt the phone left and right to move the browsing page left and right or zoom in or out of the page. ）

2: Rotate, gently shake the phone 2-3 times to achieve ** answer or open a web browser, etc.

3: The image is stable when taking pictures to prevent the impact of hand shaking on the quality of the photo. When the shutter is pressed, the shaking of the hand is recorded, and the shaking of the hand is fed back to the image processor, which can be grasped more clearly and stably**.

4: GPS inertial navigation: when the car drives to a tunnel or near a tall building in the city, there is no GPS signal, the gyroscope can be used to measure the yaw or linear motion displacement of the car, so as to continue navigation.

5: Control the game through motion sensing: Developers can use the gyroscope to detect the action (the action of the mobile phone in the 3D range) to realize the operation of the game.

For example, use your phone as a steering wheel, your phone screen is a flying fighter jet, as long as you tilt the phone up and down, left and right, the plane can do up and down, left and right.

It is used to sense the direction, tilt, and shaking of the phone.

First, a gyroscope is a sensor that can be used for multi-axis gravity sensing and has scientific, technical, and military applications. Gyroscopes are divided into sensing gyroscopes and indicating gyroscopes. Sensing gyroscopes are used in the control system, which mainly senses the horizontal, vertical and angular movement of objects; Indicating gyroscopes are used for navigation and are generally used by pilots and navigators.

The gyroscope on our phone uses gravity sensing to judge the tilt and displacement of the phone.

Gyroscopes can help us control the direction in games, and they also have a wide range of applications in taking pictures and navigating. What is the use of a gyroscope here? For example, when using a mobile phone camera, the gyroscope can play a role in anti-shake, displacing and compensating for the shaking direction of the mobile phone, and maintaining the stability of taking photos; Where the navigation signal is poor, the gyroscope will judge the moving distance according to the moving speed and events, achieve accurate navigation, and can correct the line.

Its role is to sense the movement and tilt of the device, and then make corresponding movements. It has a very special place in medicine, military and navigation. At present, mainstream mobile phones are equipped with gyroscopes, which can not only be used in games, but also in navigation apps and measurement apps, which are very convenient for people's life and work.

The first mobile phone to use a gyroscope was the iPhone 4, and the iPhone 4 created a lot of technologies and applications, and the application of the gyroscope in the mobile phone is one of them. Nintendo was the first to use this technology in consumer electronics, and now Apple can make mobile phones rely on gyroscopes for responsive operation. In the game, you can shake your phone to move the operation, which was a cross-generational development at the time.

So what is a gyroscope for? Its role is to sense the movement and tilt of the device, and then make corresponding movements. It has a very special place in medicine, military and navigation.

The gyroscope device made by people using the mechanical properties of the gyroscope is called gyroscope, which has a wide range of applications in various fields such as science, technology, and military. For example: the rotation compass, the orientation indicator, the flipping of the cannonball, the nutation of the top, the rotation of the earth under the gravitational moment of the sun (moon) (precession), etc.

The first mobile phone to use a three-axis gyroscope was the iPhone 4, which Jobs brought to us. It has three main functions: to measure the deflection angle, speed, time, etc. of the mobile phone; Able to help with camera stabilization; Assisted GPS navigation.

1. Be able to make a more realistic simulation of the game. Through the gyroscope, the deflection angle, speed, and time of the mobile phone can be measured, adding a better gaming experience; 2. It can help the camera to stabilize the image. The moment you press the shutter, the gyroscope detects the angle of the mobile phone shake, and then calculates the distance that the lens module needs to compensate according to the angle, so that the lens can counteract the shaking of the mobile phone through reverse movement, so as to achieve the absolute stillness of the lens at the moment of shooting, and improve the quality; 3. Assisted GPS navigation.

In some places where the GPS signal is weak or there is no signal, the mobile phone can calculate the current position according to the location previously positioned and the movement speed, time and direction detected by the gyroscope, so as to achieve the purpose of temporary positioning. In addition, when we navigate in the city, the correction in the direction navigation of the mobile phone will also follow the rotation, which makes it easier for us to hold the mobile phone for GPS navigation and arrive at the destination.

The use of the gyroscope is the angular velocity sensor, and the main role of the gyroscope in the mobile phone is to rotate and deflect the mobile phone, which can be measured very well, so as to command the mobile phone to make corresponding operations, the first mobile phone to use the gyroscope is Apple 4.

Gyroscopes can be used to sense or maintain direction; The gyroscope in the mobile phone can measure the rotation and cutting of the mobile phone; The first mobile phone to use a gyroscope was the iPhone 4.

His main role is to navigate; The gyroscope in the phone can not only be used for navigation, but also for stabilization and as a sensor for gaming. The first mobile phone to use a gyroscope was the iPhone.

What is a gyroscope?

Gyroscope, also known as angular velocity sensor, measures the rotational angular velocity when the physical quantity is deflected and tilted. It is a device designed based on the theory of conservation of angular momentum and consists of a rotor that rotates on the axis.

In smartphones, the gyroscope measures the angular velocity of an object when it rotates, and the angular velocity of the processor in the mobile phone is integrated to obtain the angle at which the mobile phone rotates over a certain period of time. In short, while previous phones could only sense corners relative to the horizontal plane, gyroscopes can sense corners in any direction.

What is a mobile phone gyroscope used for?

1. Navigation. Since the invention of the gyroscope, it has been used for navigation, and the Germans first applied it to the V1 and V2 rockets, so if it is used with GPS, the navigation ability of the mobile phone will reach an unprecedented level. In fact, at present, many professional handheld GPS are also equipped with gyroscopes, if the corresponding software is installed on the mobile phone, its navigation ability is no less than that of many ships and aircraft used in navigation.

2. Camera image stabilization.

The gyroscope can be used in conjunction with the camera on the phone, such as image stabilization, which will greatly improve the phone's first photo and camera capabilities.

3. Improve the game experience.

Sensors for all kinds of mobile games, such as flying games, sports games, and even some first-person shooting games, gyroscopes completely monitor the displacement of the player's hand, so as to achieve various game operation effects, such as horizontal screen to vertical screen, racing game cornering, etc.

4. As an input device.

The gyroscope can also be used as an input device, which is equivalent to a three-dimensional mouse, a function similar to the game sensor in the third largest use, and can even be considered a type.

5. Other purposes.

Augmented reality is a concept that has only emerged in recent years, and like virtual reality, it is an application of computers. Through the processing power of mobile phones or computers, people can have a deeper understanding of some objects in reality.
