How does WeChat calculate the number of walking steps? What is the principle of calculating the number of walking steps by WeChat?

1. Every smartphone is equipped with a three-axis gyroscope. The three-axis gyroscope calculates the step frequency and speed according to the shaking of the body. Wechat Movement directly reads the data of the three-axis gyroscope, carries out secondary interpretation, and calculates the number of human steps.

Generally speaking, when people lift their legs, the acceleration is the largest. The triaxial gyroscope will record the current maximum acceleration and compare it with big data. If it is equivalent to the peak, it is a step. If there are 8 peaks in a row, I can be sure that I am in motion, and the device will calculate the previous fluctuation as the number of steps. This is the basic principle of mobile phone counting steps.
