[0050] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0051] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0052] Currently, with the rapid development of science and technology, hearing aids are no longer limited to improving the auditory experience of the hearing-impaired, but are gradually moving towards intelligence and multi-functions. In order to meet users' needs for health management and daily activity monitoring, many modern hearing aids have integrated pedometer modules to help wearers easily track their steps, thereby encouraging a more active lifestyle.
[0053] However, this design faces a significant challenge in practical application: since the hearing aid is worn directly on the head, the head will inevitably move during daily activities (such as walking, running, or slight body shaking). Although this natural head movement has limited impact on the hearing aid function, it greatly affects the data accuracy of the pedometer module. Because traditional pedometer algorithms rely on accurate analysis of acceleration changes in fixed parts (such as wrists, pockets, etc.), and the complex movement pattern of the head makes it difficult for this algorithm to accurately distinguish between true walking movements and simple head shaking.
[0054] Therefore, how to improve the accuracy of the pedometer function in hearing aids is a technical problem that needs to be solved by those skilled in the art.
[0055] In an embodiment of the present application, the first data is obtained by the three-axis accelerometer, and the second data is obtained by the gyroscope, wherein the first data is the data collected by the three-axis accelerometer, and the second data is the data collected by the gyroscope, and data for step counting can be obtained; then the data corresponding to the z-axis in the first data is used as the first target data, and the data of the Z-axis in the three-axis accelerometer can be used as the target data, so as to use the time point of the acceleration mutation in the Z-axis data as the time point when the user takes a step; the peak value in the first target data is detected, and the acquisition time corresponding to the peak value is used as the target time, so as to further determine the time when the user takes a step; then the data corresponding to the target time in the second data is used as the second target data, and the number of steps is calculated according to the second target data, and the steps determined based on the three-axis accelerometer can be auxiliary verified based on the data collected by the gyroscope, thereby filtering out the false steps caused by the shaking of the head. Thus, the present application improves the accuracy of the step counting function of the hearing aid.
[0056] It should be noted that the pedometer method of the hearing aid system of the present application is performed by the hearing aid. In the following embodiments, for the sake of convenience, the description of the performing body is omitted.
[0057] Based on this, the embodiment of the present application provides a step counting method for a hearing aid system, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the step counting method for the hearing aid system of the present application.
[0058] In this embodiment, the step counting method of the hearing aid system is applied to a hearing aid, and the hearing aid includes: a gyroscope and a three-axis accelerometer. The step counting method of the hearing aid system includes steps S10 to S40:
[0059] Step S10, acquiring first data through the three-axis accelerometer, and acquiring second data through the gyroscope, wherein the first data is data acquired by the three-axis accelerometer, and the second data is data acquired by the gyroscope;
[0060] It can be understood that in this embodiment, the gyroscope is used to verify the steps determined based on the three-axis accelerometer, so as to avoid the technical problem that the calculated number of steps is higher than the actual number of steps due to the shaking of the user's head, thereby improving the accuracy of the step count.
[0061] Step S20, taking the data corresponding to the z-axis in the first data as the first target data;
[0062] It is understandable that when the user wearing the hearing aid is in motion (such as running or walking), each time the user takes a step, the user's foot will touch the ground, causing a sudden change in the user's vertical acceleration, so that an obvious peak value will be recorded on the z-axis data of the three-axis accelerometer. Therefore, in this embodiment, only the data in the z-axis direction of the three-axis accelerometer needs to be obtained.
[0063] Step S30, detecting a peak value in the first target data, and taking a collection time corresponding to the peak value as a target time;
[0064] It can be understood that the peak value refers to the local maximum value in the target data. There are usually multiple peak values in the target data obtained within the preset time. When the target data is not verified by the data collected by the gyroscope, the number of peak values can be used as the number of steps. However, in the present embodiment, the three-axis accelerometer is arranged in the hearing aid, and the hearing aid is usually worn on the head, and the head will shake with the user's body movements, thereby causing the data collected by the three-axis accelerometer to have peak values even if the user does not exercise (does not walk or run), resulting in a high number of steps calculated only by the three-axis accelerometer. Therefore, in the present embodiment, after determining the peak value in the target data, it is also necessary to use the collection time corresponding to each peak value as the target time, so as to find the data corresponding to the target time in the data collected by the gyroscope based on the target time, and then further judge the number of steps of the user based on the data corresponding to the target time in the gyroscope.
[0065] Step S40: taking the data in the second data corresponding to the target time as the second target data, and calculating the number of steps according to the second target data.
[0066] It can be understood that after the user's steps are preliminarily identified based on the data collected by the three-axis accelerometer, the false steps caused by head shaking can be filtered out from the preliminarily identified steps based on the second target data. Thus, the present application can improve the accuracy of step counting in the hearing aid.
[0067] In an embodiment of the present application, the first data is obtained by the three-axis accelerometer, and the second data is obtained by the gyroscope, wherein the first data is the data collected by the three-axis accelerometer, and the second data is the data collected by the gyroscope, and data for step counting can be obtained; then the data corresponding to the z-axis in the first data is used as the first target data, and the data of the Z-axis in the three-axis accelerometer can be used as the target data, so as to use the time point of the acceleration mutation in the Z-axis data as the time point when the user takes a step; the peak value in the first target data is detected, and the acquisition time corresponding to the peak value is used as the target time, so as to further determine the time when the user takes a step; then the data corresponding to the target time in the second data is used as the second target data, and the number of steps is calculated according to the second target data, and the steps determined based on the three-axis accelerometer can be auxiliary verified based on the data collected by the gyroscope, thereby filtering out the false steps caused by the shaking of the head. Thus, the present application improves the accuracy of the step counting function of the hearing aid.
[0068] Furthermore, based on the above-mentioned first embodiment of the step counting method for the hearing aid system of the present application, a second embodiment of the step counting method for the hearing aid system of the present application is proposed.
[0069] Please refer to Figure 2 In this embodiment, the above step S40 includes:
[0070] Step S401, calculating the head rotation speed according to the second target data;
[0071] Step S402, if it is detected that the head rotation speed is lower than a preset threshold, the peak value is used as a target peak value;
[0072] It is understandable that when the user is exercising, the user's head will also shake a little, but the shaking during exercise will not be as violent as a sudden shake or nod of the head. The gyroscope records the rotation of the head. When the user is running normally, the rotation speed of the head is not high. Therefore, when the accelerometer detects a peak, if the gyroscope shows that the head rotation speed is low, this peak is regarded as a step. If the user shakes his head suddenly, an abnormal peak may also be recorded in the Z-axis data collected by the accelerometer, but at this time the gyroscope detects that the head rotation speed is very high, and this peak will be ignored in the step counting process and will not be counted as a step.
[0073] Step S403: taking the number of target peaks as the number of steps.
[0074] Therefore, the present application can determine multiple target peaks from multiple peaks based on the head rotation speed, and then, the number of target peaks can be used as the number of steps.
[0075] In a feasible implementation manner, the above step S401 includes:
[0076] Step S4011, extracting the x-axis angular velocity, the y-axis angular velocity and the z-axis angular velocity in the second target data;
[0077] Step S4012, calculating the square sum of the x-axis angular velocity, the y-axis angular velocity and the z-axis angular velocity, and taking the arithmetic square root of the square sum as the head rotation speed.
[0078] For example, when the x-axis angular velocity, the y-axis angular velocity, and the z-axis angular velocity are a, b, and c respectively, the head rotation speed v can be expressed as:
[0079]
[0080] In a feasible implementation manner, the hearing aid further includes a GNSS receiver, and the method further includes:
[0081] Step S50, receiving positioning information through the GNSS receiver;
[0082] It is understandable that if the user is in motion, the positioning information received by the GNSS receiver on the hearing aid will change. Correspondingly, if the user is at rest, the positioning information received by the GNSS receiver on the hearing aid will not change. Therefore, on the basis of calculating the number of steps based on the hearing aid, the accurate number of steps can be further calculated based on the positioning information.
[0083] Based on this, the above step S40 further includes:
[0084] Step S404: Calculate the number of steps according to the positioning information and the second target data.
[0085] For example, in this embodiment, only when the positioning information indicates that the user's position has changed, and there is a peak in the target data, and the second target data at the time corresponding to the peak indicates that the head rotation speed is lower than a preset threshold, will it be determined that the user's step count has changed, and then the user's step count will be counted. Otherwise, it is determined that the user's step count has not changed.
[0086] Therefore, the present application can further improve the accuracy of calculating the number of steps by integrating a GNSS receiver into the hearing aid.
[0087] In a feasible implementation manner, before the above step S20, the method further includes:
[0088] Step S60, filtering the first data to obtain filtered first data;
[0089] Based on this, the above step S20 also includes:
[0090] Step S201, taking the data corresponding to the z-axis in the filtered first data as the first target data;
[0091] Furthermore, before the above step S40, the method further includes:
[0092] Step S70, filtering the second data to obtain filtered second data;
[0093] Based on this, the above step S40 further includes:
[0094] Step S405: taking the data corresponding to the target time in the filtered second data as the second target data.
[0095] It is understandable that there is noise in the data collected by the gyroscope and the three-axis accelerometer, and the noise will affect the step count. Therefore, after obtaining the first data collected by the three-axis accelerometer and the second data collected by the gyroscope, when using the first data and the second data to count the number of steps, it is necessary to filter out the noise in the first data and the second data through a filter to improve the data quality used for counting the number of steps.
[0096] Please refer to Figure 3 In a feasible implementation manner, after the above step S40, the method further includes:
[0097] Step S80, when it is detected that the number of steps reaches a preset step threshold, outputting a step reaching threshold prompt voice;
[0098] Step S90, obtaining a preset exercise strategy corresponding to the step count threshold, and outputting the exercise strategy through voice.
[0099] It should be noted that the step count reminder voice is a voice preset in the hearing aid to remind the user to reach the step count target. The exercise strategy refers to the exercise plan after reaching the step count threshold. For example, the exercise strategy can be walking slowly, adjusting breathing, etc.
[0100] In this embodiment, different exercise strategies can be set for different step count thresholds. For example, for a step count threshold with a smaller value, the exercise strategy may be to adjust breathing to support continuous exercise; for a step count threshold with a larger value, the exercise strategy may be to walk slowly to maintain physical strength while exercising and improve the safety of exercise.
[0101] In this embodiment, the present application improves the user experience by outputting a voice prompt for reaching the step count target and outputting an exercise strategy.
[0102] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the step counting method of the hearing aid system of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
