Embodiment 1

[0028] figure 1 A flow chart of the method for counting steps by user's walking provided by an embodiment of the present invention, such as figure 1 As shown, the method for user's walking step counting provided by the embodiment of the present invention comprises the following steps:

[0029] Step 101, acquiring acceleration data in the direction of gravity of the user within a set time period.

[0030] Step 102, acquiring the user's walking cycle within a set time period according to the acceleration data.

[0031] Step 103, according to the set time period and the walking cycle, the number of steps of the user within the set time period is acquired.

[0032] In step 101, acceleration data in the direction of gravity of the user may be acquired through a built-in sensor in the mobile terminal, and the sensor may specifically be an acceleration sensor built in the mobile terminal.

[0033] The method for counting steps by user's walking provided by the embodiment of the pr...

Embodiment 2

[0035] figure 2 It is a flow chart of a method for counting steps by user's walking provided by another embodiment of the present invention, image 3 for figure 2 Schematic representation of acceleration data in the direction of gravity in the illustrated embodiment. Such as figure 2 As shown, the method for counting the user's walking steps includes:

[0036] Step 201, acquiring acceleration data in the direction of gravity of the user within a set time period.

[0037] Step 202, determine the state of the user within a set time period through the acceleration data.

[0038] Step 203, if it is determined that the user is in a static state, then delete the time period corresponding to the static state from the set time period to obtain a valid time period after deletion.

[0039] Step 204, acquire the walking cycle of the user within the valid time period according to the acceleration data.

[0040] Step 205, according to the effective time period and the walking cycl...

Embodiment 3

Abstract

The invention provides a user walk step counting method and device and a mobile terminal. The user walk step counting method comprises the following steps: acquiring data about acceleration of the gravity direction of a user in a set period of time; acquiring the walk period of the user in the set period of time according to the acceleration data; and acquiring the number of steps of the user in the set period of time according to the set period of time and the walk period. According to the embodiment of the invention, the number of steps of the user can be detected through intelligent mobile equipment, and the step counting accuracy of the user is improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, and in particular to a method, device and mobile terminal for counting steps taken by a user. Background technique [0002] Most of the existing technologies detect the number of steps through wearable devices, such as sports bracelets, ankle rings, and the like. With the widespread popularity of smart phones, their user coverage far exceeds that of wearable devices, and smart phones in the prior art detect the user's steps through the user's immediate motion. If there is occasional shaking of the hand, it will lead to inaccurate step counting. Contents of the invention [0003] Embodiments of the present invention provide a method, device, and mobile terminal for counting user's walking steps, so as to detect the user's steps by means of an intelligent mobile device and improve the accuracy of user's step counting. [0004] In order to achieve the above object, embodiments of the...
