The embodiment of the present invention will be described in detail by taking an example of application to a mobile terminal.

referring to fig. 1, an embodiment of a motion information acquiring method according to the present invention is provided, where the method includes the following steps:

and S11, receiving detection data sent by the shoes, wherein the detection data comprises pressure values collected by the shoes.

and S12, comparing the pressure value collected by the shoe with a corresponding reference value, wherein the reference value is the pressure value detected by the shoe when the user stands still.

and S13, acquiring the motion information according to the comparison result.

In step S11, the shoe sends the detection data to the mobile terminal in real time or at regular time, and the mobile terminal receives the detection data. The detection data at least comprises the pressure value collected by the shoe, and preferably, the detection data also comprises the collection time of the pressure value, namely, each group of detection data comprises the pressure value and the collection time. The mobile terminal can receive detection data sent by the left shoe and the right shoe, and can also receive detection data sent by any one of the left shoe and the right shoe.

in step S12, the mobile terminal compares the pressure value collected by the shoe with the corresponding reference value, and determines whether the pressure value is smaller than the reference value or greater than or equal to the reference value. The reference value is a pressure value detected by the shoe when the user stands still, and if the pressure value detected by the shoe on the left side is M1, the pressure value detected by the shoe on the right side is M2, and the weight value of the user is M, then M is M1+ M2.

for the pressure value collected by the left shoe, comparing the pressure value with the reference value M1 of the left shoe; and comparing the pressure value collected by the right shoe with the reference value M2 of the right shoe.

In step S13, the mobile terminal obtains the current motion information of the user according to the comparison result between the pressure value collected by the shoe and the reference value, and may display the motion information on the screen. The exercise information comprises one or at least two of exercise state (such as running, walking, jumping and other states), single foot flight time, single foot supporting time, double foot flight time, double foot supporting time, step frequency (the number of steps of exercise in unit time), single foot supporting force value and the like. In specific implementation, a specific Application (APP) can be installed in the mobile terminal, and the current motion information of the user is obtained by processing the detection data sent by the shoe through the APP.

Generally, when the pressure value collected by the left shoe is smaller than the reference value, the left foot is in an empty state; and when the pressure value acquired by the left shoe is greater than or equal to the reference value, the left foot is in a grounding state. Similarly, when the pressure value collected by the right shoe is smaller than the reference value, the right foot is in an empty state; and when the pressure value acquired by the right shoe is greater than or equal to the reference value, the right foot is in a grounding state.

as shown in fig. 2, the specific process of the mobile terminal obtaining the motion information of the single foot flight time according to the comparison result between the pressure value collected by the shoe and the reference value is as follows:

S101, when two adjacent pressure values in the pressure values collected by the shoe are changed from being larger than or equal to the reference value to being smaller than the reference value, obtaining the collecting time of the pressure value smaller than the reference value as the emptying starting time.

when the pressure value acquired by the shoe is greater than or equal to the reference value, the shoe is in a grounding state; when the pressure value collected by the shoe is smaller than the reference value, the shoe is in an empty state.

When two adjacent pressure values continuously collected by the shoe change from being larger than or equal to the reference value to being smaller than the reference value, the shoe starts to change from the grounding state to the emptying state, and the collection time of the pressure value smaller than the reference value is the emptying starting time of one-time emptying state.

s102, when two adjacent pressure values in the pressure values collected by the shoe are changed from being smaller than the reference value to being larger than or equal to the reference value, obtaining the collection time of the pressure value larger than or equal to the reference value as the emptying termination time.

When two adjacent pressure values continuously collected by the shoe change from being smaller than the reference value to being larger than or equal to the reference value, the change of the shoe from the emptying state to the grounding state is indicated, and the collection time of the pressure value larger than or equal to the reference value is the emptying termination time of one emptying state.

s103, calculating the difference value between the flight ending time and the flight starting time, and taking the difference value as the flight time of a single foot.

respectively obtaining the air-out termination time and the air-out starting time of a left shoe and a right shoe, obtaining the air-out time of the left foot by subtracting the air-out starting time from the air-out termination time of the left shoe, and obtaining the air-out time of the right foot by subtracting the air-out starting time from the air-out termination time of the right shoe.

Because the left foot and the right foot are in cyclic flight and landing, the mobile terminal continuously acquires the current flight time of the single foot, can display the current flight time of the single foot in real time, and can also calculate and display the average value (such as the arithmetic average value) of the flight time of the single foot in a preset time or in one movement.

as shown in fig. 3, the specific process of the mobile terminal obtaining the motion information of the feet flight time according to the comparison result between the pressure value collected by the shoe and the reference value is as follows:

s201, when two adjacent pressure values in the pressure values collected by the shoe are changed from being larger than or equal to the reference value to being smaller than the reference value, obtaining the collecting time of the pressure value smaller than the reference value as the emptying starting time.

s202, when two adjacent pressure values in the pressure values collected by the shoe are changed from being smaller than the reference value to being larger than or equal to the reference value, the collection time of the pressure value larger than or equal to the reference value is obtained and is used as the emptying termination time.

And S203, calculating the coincidence time of the left shoe and the right shoe from the flight starting time to the flight ending time, and taking the coincidence time as the flight time of the feet.

As shown in fig. 4, it is assumed that, of the set of the right and left shoes that is closest to the start time and the end time of the flight, the start time of the flight for the right shoe is Trs1, and the end time of the flight is Tre 1; the left shoe has an emptying start time Tls1 and an emptying end time Tle 1. And Tle1 is greater than Tre1, Tls1 is greater than Trs1, the coincidence time of the two is the time period from Tls1 to Tre1, and therefore the feet emptying time T1 is equal to Tre1-Tls 1.

When the coincidence time is 0, namely the coincidence time is not coincident with the coincidence time, the situation that the feet are not in the flight state is indicated, and at the moment, the mobile terminal can display that the feet are in the flight time, or the feet are not displayed.

Because the left foot and the right foot are in cyclic flight and landing, the mobile terminal continuously acquires the current flight time of the two feet, can display the current flight time of the two feet in real time, and can also calculate and display the average value (such as the arithmetic average value) of the flight time of the two feet in a preset time or in one movement.

As shown in fig. 5, the specific process of the mobile terminal obtaining the motion information of the motion state according to the comparison result between the pressure value collected by the shoe and the reference value is as follows:

s301, when two adjacent pressure values in the pressure values collected by the shoe are changed from being larger than or equal to the reference value to being smaller than the reference value, obtaining the collecting time of the pressure value smaller than the reference value as the emptying starting time.

S302, when two adjacent pressure values in the pressure values collected by the shoe are changed from being smaller than the reference value to being larger than or equal to the reference value, the collection time of the pressure value larger than or equal to the reference value is obtained and is used as the emptying termination time.

And S303, judging whether the left shoe and the right shoe are overlapped in the soaring starting time to the soaring ending time. When there is no coincidence, the flow proceeds to step S304; when there is coincidence, the flow proceeds to step S305.

And S304, judging that the feet are not in the empty state.

When the left and right shoes are not overlapped from the rising starting time to the rising ending time, the left and right feet are not simultaneously raised, and the state that the feet are not raised is judged.

s305, judging the state of feet soaring.

When the left and right shoes are overlapped from the starting time to the ending time of the soaring, the left and right feet are soared simultaneously, and the soaring state of the two feet is judged.

S306, counting the times of the feet soaring within the preset time, and judging whether the times of the feet soaring are larger than a threshold value. When the number of times is greater than the threshold value, the process proceeds to step S307; when the number of times is less than or equal to the threshold value, the flow proceeds to step S308.

The preset time and the threshold value can be set according to actual needs, for example, the preset time can be set to 30 seconds, 1 minute, 5 minutes, 10 minutes, and the like.

and S307, judging that the exercise state is a running state.

and when the number of times of the feet in the vacated state within the preset time is larger than a threshold value, judging that the current motion state is a running state. Alternatively, when the number of times is larger than a set value larger than the threshold value, it may be determined that the jumping state is present.

And S308, judging that the motion state is a walking state.

and when the number of times of the feet in the vacated state in the preset time is less than or equal to a threshold value, judging that the current motion state is a walking state, wherein the walking state is slow walking (walking), fast walking and the like.

further, since the pressure value collected by the shoe may be larger than the user's weight due to the impact of the leg on the ground in the running state, the mobile terminal may count the average (e.g., arithmetic average) of the pressure values collected by the shoe in the running state, which are larger than or equal to the user's weight, and display the average as the value of the supporting force of the single foot. The left foot supporting force value and the right foot supporting force value can be respectively calculated and displayed.

Specifically, in the running state, the mobile terminal compares the pressure value acquired by the shoe with the pre-stored weight value of the user, extracts the pressure value greater than or equal to the weight value, and after the running state is finished, calculates the average value of all the extracted pressure values, wherein the average value is the single-foot supporting force value. Further, the maximum pressure value can be selected from the extracted pressure values to be used as the maximum single foot supporting force value.

as shown in fig. 6, the specific process of the mobile terminal obtaining the motion information of the one-foot supporting time according to the comparison result between the pressure value collected by the shoe and the reference value is as follows:

S401, when two adjacent pressure values in the pressure values collected by the shoe are changed from being smaller than the reference value to being larger than or equal to the reference value, the collection time of the pressure value larger than or equal to the reference value is obtained and used as the support starting time.

when two adjacent pressure values continuously collected by the shoe change from being smaller than the reference value to being larger than or equal to the reference value, the shoe starts to change from the emptying state to the grounding state, and the collection time of the pressure value larger than or equal to the reference value is the support (grounding) starting time of the primary grounding state.

s402, when two adjacent pressure values in the pressure values collected by the shoe are changed from being larger than or equal to the reference value to being smaller than the reference value, the collection time of the pressure value smaller than the reference value is obtained and used as the support termination time.

When two adjacent pressure values continuously collected by the shoe change from being greater than or equal to the reference value to being smaller than the reference value, the shoe starts to change from the grounding state to the emptying state, and the collection time of the pressure value smaller than the reference value is the support (grounding) termination time of the primary grounding state.

And S403, calculating the difference between the support ending time and the support starting time, and taking the difference as the single-foot support time.

respectively obtaining the support termination time and the support starting time of the left shoe and the right shoe, subtracting the support starting time from the support termination time of the left shoe to obtain the support time of the left foot, and subtracting the support starting time from the support termination time of the right shoe to obtain the support time of the right foot.

Because the left foot and the right foot are in cyclic flight and landing, the mobile terminal continuously acquires the current single-foot supporting time, can display the current single-foot supporting time in real time, and can also calculate and display the average value (such as the arithmetic average value) of the single-foot supporting time in the preset time or in one movement.

as shown in fig. 7, the specific process of the mobile terminal obtaining the motion information of the supporting time of both feet according to the comparison result between the pressure value collected by the shoe and the reference value is as follows:

S501, when two adjacent pressure values in the pressure values collected by the shoe are changed from being smaller than the reference value to being larger than or equal to the reference value, the collection time of the pressure value larger than or equal to the reference value is obtained and used as the support starting time.

s502, when two adjacent pressure values in the pressure values collected by the shoe are changed from being larger than or equal to the reference value to being smaller than the reference value, the collection time of the pressure value smaller than the reference value is obtained and used as the support termination time.

s503, calculating the coincidence time of the left shoe and the right shoe from the support starting time to the support ending time, and taking the coincidence time as the supporting time of the feet.

As shown in fig. 8, in a set of the support starting time and the support ending time which are the closest to the left shoe and the right shoe, the support starting time of the right shoe is Trs2, and the support ending time is Tre 2; the support start time of the left shoe is Tls2 and the support end time is Tle 2. And Tle2 is greater than Tre2, Tls2 is greater than Trs2, the superposition time of the two is the time period from Tls2 to Tre2, and therefore the supporting time T2 of the two feet is Tre2-Tls 2.

When the coincidence time is 0, that is, the coincidence time is not coincident with the time, it indicates that the state of supporting both feet does not occur, and at this time, the mobile terminal may display that the time of supporting both feet is 0 or not display the time of supporting both feet.

because the left foot and the right foot are in cyclic flight and landing, the mobile terminal continuously acquires the current supporting time of the two feet, can display the current supporting time of the two feet in real time, and can also calculate and display the average value (such as the arithmetic average value) of the supporting time of the two feet in a preset time or in one movement.

The specific mode that the mobile terminal acquires the motion information of the step frequency according to the comparison result of the pressure value acquired by the shoe and the reference value is as follows: counting the change times of two adjacent pressure values in the pressure values collected by the shoe in unit time from being smaller than the reference value to being larger than or equal to the reference value or from being larger than or equal to the reference value to being smaller than the reference value; and calculating the sum of the change times of the left shoe and the right shoe, and taking the calculation result as the step frequency.

When two adjacent pressure values acquired by the shoe change from being smaller than the reference value to being larger than or equal to the reference value, the shoe changes from the soaring state to the landing state, and the change times are the steps of a single foot; the number of steps of the left foot and the right foot moving in unit time is counted respectively, and then the sum is carried out, so that the number of steps of the left foot and the right foot moving together in unit time (namely the number of times of alternation of the two legs in unit time), namely the step frequency, is obtained.

in other embodiments, the detection data sent by the shoe may not include the collection time, and the shoe collects the pressure value at a preset frequency (e.g. 1KHZ), at this time, the mobile terminal may obtain the motion information of the single foot flight time or the single foot support time by:

optionally, the mobile terminal first counts the number of pressure values continuously smaller than the reference value in the pressure values collected by the shoe, then calculates a quotient obtained by dividing the counted number by a preset frequency, and takes the quotient as the single foot flight time. Specifically, the mobile terminal can count the number through a counter, and when the pressure value is smaller than the reference value, the counter is increased by 1; and when the pressure value is greater than or equal to the reference value, acquiring the number accumulated by the current counter as the number of the pressure values which are continuously smaller than the reference value, simultaneously resetting the counter, starting counting again by the counter until the pressure value is smaller than the reference value again, and repeating the steps in a circulating manner.

optionally, the mobile terminal first counts the number of pressure values continuously greater than or equal to the reference value among the pressure values collected by the shoe, then calculates a quotient obtained by dividing the counted number by a preset frequency, and takes the quotient as the single-foot supporting time.
