Embodiment Construction

[0031] figure 1 It is a functional block diagram of an electronic device according to an embodiment of the present invention. In this embodiment, the electronic device 100 includes a detection unit 110 , a storage unit 120 and a processing unit 130 . The electronic device 100 is, for example, a smart phone, a tablet computer, a watch, a pedometer, a personal digital assistant (PDA for short), a wearable device or other similar products.

[0032] The detection unit 110 is, for example, a detection element such as an accelerometer, a magnetometer, a gyroscope, or a combination thereof, but the embodiments of the present invention are not limited thereto. The detection unit 110 can detect the orientation of the electronic device 100 and a plurality of first triaxial acceleration values. The orientation is, for example, an azimuth of the electronic device 100 in a three-dimensional space. The plurality of first triaxial acceleration values ​​are, for example, a plurality of tri...

Abstract

The invention provides a step calculation method and an electronic apparatus thereof. The method includes the following steps: obtaining a plurality of first triaxial acceleration values of the electron apparatus; removing gravitational acceleration with a specific proportion from each first triaxial acceleration value so as to generate a plurality of second triaxial acceleration values; calculating a plurality of inner product values and a plurality of outer product values according to the plurality of second triaxial acceleration values; judging whether a user of the electronic apparatus is in a walking state according to the plurality of second triaxial acceleration values, and if so, setting the plurality of the inner product values as a plurality of reference values; otherwise, setting the plurality of outer product values as the plurality of reference values; and calculating the step number corresponding to the plurality of second triaxial acceleration values according to the plurality of the reference values.

Description

technical field [0001] The present invention relates to a step counting method and its electronic device, and in particular to a step counting method and its electronic device for counting steps based on a signal detected by a Microelectromechanical system (MEMS) sensor. Background technique [0002] A pedometer is a device that can be used to count the number of steps a user takes while walking or running. There are traditionally a number of methods that can be used to have a pedometer count steps. Among these methods, the most direct one is to place an object with weight in the pedometer, and use, for example, an electrical method or a mechanical method to measure the bounce rate of the object. ). [0003] However, in order to accommodate the above-mentioned objects and measuring components, the volume of the pedometer must generally be designed to be relatively large. If the pedometer is designed to be smaller in size, the method of counting the number of steps of the ...
