If the device is not worn properly, it will directly affect the accuracy of the wearable device's monitoring of the user's heart rate, blood oxygen and exercise conditions, and thus affect the user experience.

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] The core of this application is to provide a wearable device wearing status detection method and related components, combine the acceleration data and impedance value data collected by the wearable device, analyze and determine the cause of abnormal wearing of the wearable device, and promptly remind the user to adjust the wearing status, thereby improving the user experience.

[0054] With the continuous development of science and technology, various wearable devices have entered people's lives and improved people's quality of life. In the process of using wearable devices, the wearing state of wearable devices is crucial to the user's experience. At present, infrared ranging and other technical means can be used to detect whether the wearable device is in a wearing state. However, when it is determined that the wearable device is worn abnormally, due to the complexity of the abnormal wearing situation, it can be roughly divided into loose wearing, not fully contacting the user's skin, and not contacting the user's skin. Infrared ranging cannot determine which wearing abnormal situation is currently in.

[0055] In order to improve the accuracy of wearing status monitoring of wearable devices, remind users to adjust the wearing status, and thus improve user experience, the embodiment of the present application provides a method for detecting the wearing status of a wearable device, which combines acceleration data and impedance value data collected by the wearable device, analyzes and determines the cause of the current abnormal wearing of the wearable device, and then promptly reminds users to make adjustments, thereby improving user experience.

[0056] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0057] Figure 1 A flowchart of a method for detecting the wearing status of a wearable device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0058] S10: Obtaining the impedance value collected by the wearable device;

[0059] The wearable device provided in the embodiment of the present application is a device with a bioelectrode, and when the wearable device comes into contact with the user's skin, the user's impedance value data can be collected. Therefore, before acquiring the wearable device, it can be determined based on the infrared measurement of the wearable device whether the distance between the wearable device and the user's skin is within a preset range. If it is within the preset range, it is determined that the wearable device is in contact with the skin, and the impedance value collected by the wearable device is obtained at this time.

[0060] S11: respectively determining a first ratio and a second ratio of the number of valid sample points of the impedance value in the first preset impedance interval and the second preset impedance interval within the preset time length to the total number of sample points within the preset time length; wherein the maximum value in the first preset impedance interval is less than or equal to the minimum value in the second preset impedance interval;

[0061] In a specific embodiment, after obtaining the user's impedance value, in order to determine whether the wearable device is worn normally, a first ratio and a second ratio of the number of valid sample points of the acquired impedance value in the first preset impedance interval and the second preset impedance interval within the preset time length to the total number of sample points of all impedance values ​​within the preset time length are respectively determined.

[0062] For example, the total number of sample points within the preset time length T1 is Y, the first preset impedance interval is [Thr1, Thr2], and the number of valid sample points within the first preset impedance interval [Thr1, Thr2] is X1, the second preset impedance interval is [Thr3, Thr4], and the number of valid sample points within the second preset impedance interval [Thr3, Thr4] is X2, the first ratio is P1, the second ratio is P2, then P1=X1 / Y, P2=X2 / Y.

[0063] S12: When the first ratio is less than a preset threshold, determining that the wearable device is worn abnormally, and determining the current motion state of the user according to the acceleration data collected by the wearable device;

[0064] Figure 2(a) is a schematic diagram of impedance value data and combined acceleration data of a wearable device provided in an embodiment of the present application. Figure 2(a) illustrates the impedance value data and combined acceleration data when the wearable device is not worn and the user is in a stationary state or a moving state. The horizontal axis of the curve A1 in Figure 2(a) represents the number of sample points, and the vertical axis represents the impedance value. It can be understood that the number of sample points is related to the sampling rate. For example, when the sampling rate is 50 / second, the value of 200 in the horizontal axis represents that the number of samples of the internal impedance value in 4 seconds is 200. As can be seen from Figure 2(a), when the wearable device is not worn, that is, it does not contact the user's skin, the user's impedance value data does not change significantly.

[0065] Figure 2(b) is a schematic diagram of impedance value data and combined acceleration data of another wearable device provided in an embodiment of the present application. Figure 2(b) illustrates the impedance value data and combined acceleration data when the wearable device is normally worn and the user is in a stationary state or in motion. It can be seen from Figure 2(b) that when the wearable device is in good contact with the skin, that is, when it is normally worn, the user's impedance value data also does not change significantly.

[0066] FIG2(c) is a schematic diagram of impedance value data and combined acceleration data of another wearable device provided in an embodiment of the present application. FIG2(c) illustrates the impedance value data and combined acceleration data of the user in motion when the tightness of the wearable device does not meet the preset conditions, for example, when the wearable device is worn loosely. It can be seen from FIG2(c) that when the wearable device is worn abnormally, that is, when the tightness of the wearable device does not meet the preset conditions, the user's impedance value data changes significantly.

[0067] Figure 2(d) is a schematic diagram of impedance value data and combined acceleration data of another wearable device provided in an embodiment of the present application. Figure 2(d) illustrates the impedance value data and combined acceleration data when the wearable device is worn but does not fully contact the user's skin, and the user is in a stationary state. It can be seen from Figure 2(d) that when the wearable device is worn abnormally, that is, the wearable device does not fully contact the skin, the user's impedance value data is larger than the impedance value data when the contact is good.

[0068] according to Figure 2(a)-Figure 2(d)It can be seen that when the wearable device is worn normally, the impedance value of the user does not change much regardless of whether the user is in a stationary state or in motion, and the fluctuation range is relatively fixed. Therefore, when the first ratio is greater than or equal to the preset threshold value K1, that is, P1≥K1, it can be determined that the current wearable device is worn normally. If the first ratio is less than the preset threshold value, that is, P1<K1, it is determined that the wearable device is worn abnormally, and the user's current motion state is determined based on the acceleration data collected by the wearable device, so as to further combine the user's current motion state with the impedance value data to determine the cause of the current wearing abnormality.

[0069] It should be noted that Figure 2(a) shows the normal wearing condition. Figure 2(c)-Figure 2(d) For the case of abnormal wearing, it can be seen from the figure that the maximum impedance value when wearing normally is less than the minimum impedance value when wearing abnormally. In addition, when the wearable device is worn abnormally, the fluctuation range of the impedance value is large and unstable. Therefore, in order to further determine the cause of the abnormal wearing of the wearable device, it is necessary to determine whether the wearable device is worn normally based on the first ratio, and further determine the cause of the abnormal wearing based on the second ratio. Therefore, the maximum value in the first preset impedance interval is less than or equal to the minimum value in the second preset impedance interval. In other words, when it is determined that the current wearable device is worn abnormally, since the fluctuation range of the impedance value is large and unstable when wearing abnormally, it is necessary to expand the impedance value interval to further determine the cause of the abnormal wearing.

[0070] S13: Determine whether the second ratio meets a preset condition to determine the reason why the wearable device is abnormally worn in the current motion state.

[0071] After determining the current motion state of the user in step S12, it is determined whether the second ratio meets a preset condition to determine the reason why the wearable device is abnormally worn in the current motion state.

[0072] Specifically, if the current motion state is a stationary state, when the second ratio is less than the first preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the wearable device does not contact the user's skin; when the second ratio is not less than the first preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the wearable device does not completely contact the user's skin.

[0073] If the previous motion state is the motion state, when the second ratio is less than the second preset value, it is determined that the reason for the abnormal wearing of the wearable device is that it does not contact the user's skin; when the second ratio is not less than the second preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the tightness of the wearable device does not meet the preset conditions.

[0074] The detection method of the wearing state of the wearable device provided in the embodiment of the present application includes: obtaining the impedance value collected by the wearable device, and respectively determining the first ratio and the second ratio of the effective sample points of the impedance value in the first preset impedance interval and the second preset impedance interval within the preset time length to the total sample points within the preset time length, wherein the maximum value in the first preset impedance interval is less than or equal to the minimum value in the second preset impedance interval. When the first ratio is less than the preset threshold value, it is determined that the wearable device is worn abnormally, and the current motion state of the user is determined based on the acceleration data collected by the wearable device, and the reason for the abnormal wearing of the wearable device in the current motion state is determined by judging whether the second ratio meets the preset conditions. It can be seen that the technical solution provided by the present application preliminarily determines whether the current wearable device is worn abnormally based on the impedance data of the user, and then combines the acceleration data and the impedance value data to determine the reason for the abnormal wearing of the wearable device, accurately reminds the user of the current wearing condition of the wearable device, and then promptly reminds the user to make adjustments to improve the user experience.

[0075] In a specific embodiment, when the current motion state is a static state, determining whether the second ratio satisfies a preset condition to determine the reason why the wearable device is abnormally worn in the current motion state includes:

[0076] Determining whether the second ratio is less than the first preset value;

[0077] If it is less than the first preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the wearable device does not contact the user's skin;

[0078] If it is not less than the first preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the wearable device does not completely contact the user's skin.

[0079] As shown in Figure 2(d), when the wearable device is worn abnormally, and the current motion state of the user is determined to be static according to the acceleration data, the reasons for the abnormal wearing include not contacting the user's skin and not completely contacting the user's skin. Specifically, when it is determined that the second ratio is less than the first preset value, it is determined that the wearable device is not in contact with the user's skin, that is, the user is not wearing the wearable device, and when it is determined that the second ratio is not less than the first preset value, it is determined that the wearable device is not completely in contact with the user's skin.

[0080] Further, when the current motion state is the motion state, determining whether the second ratio satisfies a preset condition to determine the reason why the wearable device is abnormally worn in the current motion state includes:

[0081] Determine whether the second ratio is less than a second preset value; wherein the second preset value is less than the first preset value;

[0082] If it is less than the second preset value, it is determined that the reason for the abnormal wearing of the wearable device is that it does not contact the user's skin;

[0083] If it is not less than the second preset value, it is determined that the reason for the abnormal wearing of the wearable device is that the tightness of the wearable device does not meet the preset condition.

[0084] As shown in FIG2(c), when the wearable device is worn abnormally, and the current motion state of the user is determined to be a motion state according to the acceleration data, the reasons for the abnormal wearing include not contacting the user's skin and the wearing tightness not meeting the preset condition. Specifically, when it is determined that the second ratio is less than the second preset value, it is determined that the wearable device is not in contact with the user's skin, that is, the user is not wearing the wearable device. When it is determined that the second ratio is not less than the second preset value, it is determined that the wearing tightness of the wearable device does not meet the preset condition, that is, the wearable device is worn relatively loosely, and it cannot be guaranteed that the user can accurately measure the physiological characteristic data such as heart rate when using the wearable device.

[0085] It is worth noting that, as can be seen from FIG. 2(c) and FIG. 2(b), the minimum impedance value of the user's current state in motion is smaller than the minimum impedance value in a stationary state, that is, the contact between the wearable device and the user's skin changes with the motion conditions. Therefore, the first preset value is greater than the second preset value.

[0086] In summary, after the wearable device is initially determined to be abnormally worn through the first ratio, the motion state of the wearable device is determined based on the acceleration data collected by the wearable device, and then the motion state is combined with the second ratio to determine the cause of the abnormal wearing. After determining the cause, the abnormal wearing signal and the corresponding abnormal cause are sent to the terminal to remind the user to adjust the wearing state in time.

[0087] The wearable device wearing state detection method provided in the embodiment of the present application determines the wearable device wearing abnormality, determines the user's current motion state according to the acceleration data, and determines whether the second ratio meets the preset conditions, thereby determining the cause of the wear abnormality. That is, the motion state and the impedance value are combined to determine the cause of the wearable device wearing abnormality, and the user is reminded to adjust the wearing state in time, thereby improving the accuracy of the wearable device in collecting physiological characteristics, thereby improving the user experience.

[0088] As a preferred embodiment, determining the current motion state of the user based on the acceleration data collected by the wearable device includes:

[0089] Determine the total acceleration corresponding to the X-axis acceleration, Y-axis acceleration and Z-axis acceleration at each moment within a preset time length;

[0090] Determine whether the number of times the combined acceleration is greater than a threshold is greater than a preset number;

[0091] If it is greater than the preset number, the user's current motion state is determined to be a motion state;

[0092] If it is not greater than the preset number, it is determined that the user's current motion state is a stationary state.

[0093] In fact, when determining the user's current motion state, it is necessary to obtain the acceleration data collected by the wearable device within a preset time, that is, to establish a spatial coordinate system, and obtain the acceleration on the X-axis, the acceleration on the Y-axis, and the acceleration on the Z-axis at different times within the preset time, that is, the X-axis acceleration a x , Y-axis acceleration a y and Z-axis acceleration a z . And the total acceleration A is calculated by the following formula:

[0094]

[0095] After obtaining the combined accelerations A, when the number of combined accelerations A greater than the threshold is greater than a preset number, it can be determined that the current state of the user is a moving state; otherwise, it is determined that the current state of the user is a stationary state.

[0096] It is worth noting that it is necessary to ensure that the number of combined accelerations obtained within the preset time length each time is the same. If not, it is determined whether the ratio of the number of combined accelerations A greater than the threshold to the total number satisfies the preset ratio. If so, it is determined that the user's current state is a moving state, otherwise, it is determined that the user's current state is a stationary state.

[0097] The wearable device wearing state detection method provided in the embodiment of the present application determines the current motion state of the user by determining the combined acceleration corresponding to the X-axis acceleration, Y-axis acceleration and Z-axis acceleration at each moment within a preset time, and when it is determined that the number of times the combined acceleration is greater than the threshold is greater than the preset number, the user's current state is determined to be a motion state, otherwise, the user's current state is determined to be a static state. The cause of abnormal wear of the wearable device can then be determined based on the current user's motion state combined with the impedance value.

[0098] On the basis of the above embodiment, in order to further improve the detection accuracy of the wearing state of the wearable device, after determining that the cause of the abnormal wearing of the wearable device is that the wearable device does not contact the user's skin, the method further includes:

[0099] Determine whether the distance between the wearable device and the skin is within a preset range based on infrared ranging;

[0100] If it is within the preset range, it is determined that the cause of the abnormal wearing of the wearable device is wrong;

[0101] If it is not within the preset range, a warning signal indicating that the wearable device is worn abnormally is output.

[0102] It can be understood that after determining that the reason for the abnormal wearing of the wearable device is that it does not contact the user's skin according to the second ratio, in order to further determine whether the judgment is correct, it is possible to determine whether the distance between the wearable device and the skin is within a preset range based on infrared ranging. If it is within the preset range, the reason for the abnormal wearing of the wearable device may be a wrong judgment. At this time, an abnormal judgment signal is output to remind the user.

[0103] Furthermore, when it is confirmed that the distance between the wearable device and the skin is not within a preset range, it can be determined that the wearable device is indeed not worn, that is, not in contact with the skin. At this time, a prompt signal is output indicating that the reason for the abnormal wearing of the wearable device is that it does not contact the user's skin, so as to remind the user to adjust the wearing status in time.

[0104] The method for detecting the wearing status of a wearable device provided in the embodiment of the present application, after determining that the cause of the abnormal wearing of the wearable device is that it does not contact the user's skin, further determines whether the cause of the abnormal wearing of the wearable device is accurately detected through infrared ranging, thereby improving the detection accuracy of the wearing status of the wearable device and further improving the user experience.

[0105] As a preferred embodiment, in order to further improve the detection accuracy of the wearing state of the wearable device on the basis of the above embodiment and save resources, before obtaining the impedance value collected by the wearable device, it also includes:

[0106] Determine whether the distance between the wearable device and the skin is within a preset range based on infrared ranging;

[0107] If it is within the preset range, proceed to the step of obtaining the impedance value collected by the wearable device;

[0108] If it is not within the preset range, enter the step of determining whether the distance between the wearable device and the skin is within the preset range based on infrared ranging.

[0109] It is understandable that if the user's impedance value is always obtained, when the user is not wearing the wearable device, it will undoubtedly cause a waste of resources. Therefore, infrared ranging can be used to determine whether the distance between the wearable device and the skin is within a preset range to preliminarily determine whether the user is wearing the wearable device. Specifically, if it is within the preset range, it is determined that the wearable device is in a wearing state. At this time, the wearable device can collect the user's impedance value to further determine whether the wearable device is worn normally based on the impedance value.

[0110] If it is not within the preset range, it is determined that the current user is not wearing the wearable device. In order to avoid wasting resources, there is no need to judge the wearing status of the wearable device based on the impedance value. It is only necessary to continue to determine whether the distance between the wearable device and the skin is within the preset range based on infrared ranging.

[0111] It should be noted that in addition to judging the wearing status of the wearable device based on infrared ranging, it can also be determined based on capacitance value and other methods, which is not limited to this application.

[0112] The method for detecting the wearing status of a wearable device provided in the embodiment of the present application determines whether the distance between the wearable device and the skin is within a preset range based on infrared ranging before obtaining the impedance value collected by the wearable device, thereby avoiding waste of resources and improving the detection accuracy of the wearing status of the wearable device.

[0113] During implementation, in order to avoid collecting invalid impedance value data, which would reduce the detection accuracy of the wearing status of the wearable device, after obtaining the impedance value collected by the wearable device, the impedance value is subjected to sliding mean filtering to filter out invalid data and avoid noise interference.

[0114] The wearing status detection method of a wearable device provided in an embodiment of the present application performs a sliding mean filtering on the impedance value after acquiring the impedance value collected by the wearable device, thereby avoiding the collection of invalid impedance value data, which may lead to misjudgment of the wearing status of the wearable device, and further improving the user experience.
