In fact, as early as more than 100 years ago, gyroscopes were used in the field of navigation, and with the improvement of gyroscopes in terms of structure and principle, it has gradually been applied to aerospace, missiles, automobiles, cell phones, and other consumer electronic products.
By definition, a gyroscope is a device used to sense and maintain direction, which is designed based on the theory of conservation of angular momentum and is mainly used to measure and maintain direction. A three-axis gyroscope can simultaneously measure position, trajectory, and acceleration in six directions.
Many smartphones today use MEMS (microelectromechanical) gyroscopes. Their small size, low power consumption, ease of digitization and intelligence, and especially their low cost and ease of mass production make them ideal for cell phones, automotive traction control systems, and medical devices that require mass production. Gyroscope with other sensors on the phone, enough for our daily use!
Three-axis gyroscope in the role of mobile phones
In October this year, Huawei launched the nova series for young people, Huawei nova in addition to the common light / distance sensor, fingerprint sensor it also has a built-in three-axis gyroscope sensor.
The three-axis gyroscope in Huawei nova together with other sensors can help the phone reconstruct the user's spatial action model. Let nova perceive what Pose we are posing. so in real life, Huawei nova built-in three-axis gyroscope in which kind of use scenarios to play a role?
Phone use to three-axis gyroscope scene
(1) game operation
In daily life, we most commonly used to the gyroscope scene is to use the phone to play the game, compared to the traditional gravity sensing can only sense the left and right two dimensions, the Huawei nova built-in three-axis gyro through the measurement of the angular velocity of the action of the yawning, tilting, and so on, you can realize the hand control the game protagonist vision and direction. the game protagonist's field of view and direction.
For example, in shooting games, Huawei nova can act as a directional turntable for the machine gun, we just need to change different tilts, and the collimator will make left-right-backward linkage accordingly. There are more and more games on the market now that support three-axis gyroscopes.
(2)Assisted navigation
Huawei nova built-in three-axis gyroscope can assist inertial navigation, when we enter some tunnels, bridges or near tall buildings without GPS signals, nova built-in three-axis gyroscope will measure the direction of the movement and speed, multiply the speed by the time to get the distance of the movement, to achieve accurate positioning navigation, and can correct the navigation line, and in the When positioning, the pointer follows better, and is more accurate than the general positioning of cell phones that do not have a gyroscope.
(3)Gesture function
Huawei nova has a variety of built-in gesture functions, and they all require the assistance of a three-axis gyroscope. Like picking up the phone and then the ringtone diminishes; taking the nova to your ear and then you can answer a call or make a call; moving icons or window widgets to another screen by tilting the phone left or right in the home screen editing state.
In fact, Huawei nova built-in three-axis gyroscope has quite a lot of functions, we need to slowly dig! In addition, the gyroscope can also be used in smartphones to assist the camera's anti-shake, make step counting more accurate, assist the user interface to realize the action demonstration and even in the future will be used in the field of VR.
Summary
The seemingly insignificant gyroscope is actually quite important in cell phones, as it will affect the user's actual experience in many scenarios. Huawei nova has a built-in three-axis gyroscope, which plays a crucial role in game operation, gesture functions and assisted navigation.
