Hello everyone, Lin Fei to answer the above questions, gyroscope function iPhone, gyroscope function many people do not know, now let's take a look!

For today's mobile phones, compared with the original Nokia PHS, mobile phones have more built-in hardware and new technologies to achieve intelligence. For example, better processors and chips can run software better, better screens and monitors can display better picture quality, and cameras and front cameras equivalent to cameras can make people interested in taking pictures. There are also gadgets such as gyroscopes and flashlights that make mobile phones more versatile. So what is the purpose of this gyroscope?

Brief introduction

Gyroscopes are also called angular velocity sensors, which are different from accelerometers. The physical quantity it measures is the angular velocity of rotation during deflection and tilt. On mobile phones, only accelerometers cannot measure or reconstruct complete 3D motion. If rotational motion cannot be measured, the gravity sensor can only detect axial linear motion. The gyroscope can well measure rotation and deflection, so as to accurately analyze and judge the actual action of the user. Then according to the action, you can do the corresponding operation on the mobile phone!

Characteristics

Among consumer products, the most successful application of gyroscopes is to make somatosensory game handles in Wii games to control the game. Through the handheld Wii Motion Plus handle, players can play sports games such as table tennis and tennis through their own motion control screen, or by turning the handle, they can play video games of driving. Secondly, the air mouse, by moving the mouse in the air, you can control the cursor on the screen to move flexibly up and down.

App application

1. Motion-sensitive GUI: the selection of menus and directories and the execution of operations are realized by slightly tilting and deflecting the phone.

2: rotate and gently shake the phone 2-3 times to answer the phone or open a web browser.

3. When taking pictures, the image is stable to prevent the impact of hand shaking on the quality of photos. When the shutter is pressed, the hand shaking action is recorded and fed back to the image processor, so that a clearer and more stable picture can be captured.

4.GPS inertial navigation: when the car is driving in the city's tunnel or near high-rise buildings, when there is no GPS signal, the vehicle's yaw or linear motion displacement can be measured by gyroscope to continue navigation.

5. Controlling games through motion sensing: a place that gives application developers more room for innovation. Developers can realize the operation of the game through the results of gyroscope motion detection. For example, the mobile phone is used as the steering wheel, and the mobile phone screen is the fighter in flight. As long as you tilt the phone up and down, the plane can move up and down.

The above is about the function and use of mobile phone built-in gyroscope. As we can see from the above, although such a gadget looks inconspicuous, it is essential for today's smartphones. Not only for the compass function of the phone, but also for the flip of the horizontal and vertical screen of the phone and the anti-shaking of shooting, and even to play some popular gravity sensing games, gyroscopes are needed to support it, which shows how effective it is. Today's mobile phones are substandard smartphones if they are not equipped with gyroscopes.

At the end of this article, I hope it will be helpful to you.
