[0039] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0040] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0041] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0042] The wearable device provided in this application can be a portable device that can be integrated into the user's clothes or accessories, has computing functions, and can be connected to mobile phones and various terminal devices. For example, the wearable device 100 can be a smart watch, a blood pressure bracelet, an upper arm blood pressure monitor, etc. This application does not specifically limit the type of wearable device.

[0043] It should be noted that the wearable device provided in the embodiment of the present application has a blood pressure measurement function and / or a blood oxygen measurement function and / or a heart rate measurement function.

[0044] Wearable devices usually use the principle of oscillometric method to measure blood pressure. Specifically, the vibration caused by blood flowing and hitting the blood vessel wall is used to obtain the fluctuation envelope originating from the blood vessel wall, and the blood pressure value is obtained through the relationship between the fluctuation envelope and the arterial blood pressure. During the specific measurement, the wearable device needs to be worn on the human limbs, and the airbag of the wearable device is used to compress the artery of the user being measured. When the blood pressure in the artery of the user being measured hits the airbag, the air pressure inside the airbag produces pressure fluctuations, and then the blood pressure index of the user being measured is calculated through the fluctuation of the air pressure inside the airbag.

[0045] Wearable devices usually use photoelectric measurement to measure heart rate, specifically, a beam of light is emitted to the surface of the skin, and the light intensity at different times is obtained through the changes in blood flow caused by the heartbeat, and the heart rate value is obtained through the light intensity at different times. Similar to blood pressure measurement, when measuring heart rate, the wearable device needs to be worn on the human limbs. When a beam of light with a fixed wavelength is irradiated onto the surface of the skin, the light beam will transmit the light to the sensor by transmission or reflection. In this process, the light intensity detected by the sensor will be weakened due to absorption by the skin muscles and blood. The absorption of light by the skin, muscle tissue, etc. remains constant throughout the blood circulation, but the blood volume in the skin will change pulsatingly under the action of the heart. When the heart contracts, the peripheral blood volume is the largest, the light absorption is also the largest, and the detected light intensity is the smallest. When the heart is in diastole, on the contrary, the maximum light intensity is detected, that is, the detected light intensity changes pulsatingly, so as to calculate the user's heart rate value.

[0046] Wearable devices usually use photoelectric measurement to measure blood oxygen, specifically emitting red light and infrared light to the skin surface. Since oxygen-saturated hemoglobin is reddish, when receiving red light, the reflectivity of red light is higher, while the reflectivity of infrared light is lower. Conversely, when oxygen-saturated hemoglobin is insufficiently oxygenated, the reflectivity of red light is lower, while the reflectivity of infrared light is higher. By analyzing the different reflectivities of red light and infrared light, the blood oxygen value is obtained. Similar to heart rate measurement, when measuring blood oxygen, the wearable device needs to be worn on a person's limbs.

[0047] In summary, when the wearable device performs the above-mentioned measurement functions, it is necessary to wear the wearable device on a person's limbs, but the tightness of wearing will affect the accuracy of the measurement results. Take blood pressure measurement as an example. For example, if the wearable device is worn too loosely, the airbag needs to be filled with more gas to compress the artery of the measured user. At this time, the pressure in the airbag increases compared to when it is worn normally, which will cause the measured blood pressure value to be higher. On the contrary, if the wearable device is worn too tightly, the pressure in the airbag decreases compared to when it is worn normally, which will cause the measured blood pressure value to be lower. It can be seen that the tightness of wearing the wearable device will affect the accuracy of the measurement results. Based on this, the embodiment of the present application provides a method for detecting the wearing of a wearable device and a wearable device.

[0048] Figure 1 1 is a schematic diagram of a structure of a wearable device 100 provided in an embodiment of the present application. In some embodiments, the wearable device 100 may be a smart watch or a bracelet that can be worn around a user's wrist.

[0049] like Figure 1 As shown, the wearable device 100 may include a main body 110, a wristband 120 and a blood pressure detection component 130. The wristband 120 may surround and fit a user's body part, such as the user's wrist, upper arm, ankle or other body part, so that the main body 110 is fitted to the user's part to be detected. The wearable device 100 may implement a blood pressure measurement function through the blood pressure detection component 130.

[0050] The blood pressure detection component 130 may include an airbag 131, an air pump 132 and an air pressure sensor (not shown). The airbag 131 may be arranged on the inner surface of the wristband 120. The air pump 132 may be arranged inside the main body 110 and communicated with the airbag 131 through the air tube 133 to inflate or deflate the airbag 131. The air pressure sensor may also be arranged inside the main body 110 and connected to the airbag 131 to detect the air pressure change of the airbag 131.

[0051] It can be understood that the inner surface of the wristband 120 can be the side of the wristband 20 that fits in contact with the user's body part.

[0052] For example, when a user measures blood pressure by wearing the wearable device 100 on the wrist, the wearable device 100 can control the air pump 132 to start the inflation action, and the air pump 132 can inflate the airbag 31 through the trachea 133, so that the airbag 131 is pressurized and expanded, thereby compressing the radial artery of the wrist. In this case, the air pressure in the airbag 131 can produce air pressure fluctuations. The wearable device 100 can obtain the air pressure wave signal in the airbag 131 through the air pressure sensor, and calculate the user's diastolic and systolic pressure based on the air pressure wave signal to achieve the blood pressure measurement function.

[0053] When the blood pressure measurement process is completed, the wearable device 100 can control the air pump 132 to stop the inflation action, and the gas in the airbag 131 can be discharged through the air pump 132 to be in a state where the blood pressure can be measured again.

[0054] Optionally, in some embodiments, the wearable device may further include a photoplethysmography (PPG) sensor, which is used to collect the user's heart rate and blood oxygen.

[0055] The following first introduces several scenarios in which the wearable device wearing detection method provided in the embodiments of the present application is applicable in conjunction with a graphical user interface (GUI).

[0056] It should be noted that in the GUI involved below, the wearable device is taken as a smart watch as an example, but it should not be understood as a specific limitation on the embodiments of the present application.

[0057] Figure 2 A set of GUIs provided by an embodiment of the present application is shown.

[0058] like Figure 2 As shown, the smart watch displays an interface 201, which is a desktop. The smart watch displays an icon 202 on the interface 201, which corresponds to the wearing detection function. When the smart watch detects that the user clicks the icon 202, it can respond to the operation and detect the tightness of the smart watch. When it is determined that the smart watch is worn too loose, it can display the following information: Figure 2 The GUI shown in (b) in FIG. 1 may display the following information when it is determined that the wearing is too tight: Figure 2 The GUI shown in (c) in FIG. 1 may display the following when worn normally: Figure 2 GUI shown in (d).

[0059] like Figure 2 As shown in (b) in the figure, when the smart watch completes the detection and determines that it is worn too loose, the detection result can be displayed on the interface 203: "It is currently worn too loose, please adjust it in time."

[0060] like Figure 2 As shown in (c) in the figure, when the smart watch completes the detection and determines that the wearer is too tight, the detection result can be displayed on the interface 203: "It is currently worn too tight, please adjust it in time."

[0061] like Figure 2 As shown in (d) in the figure, when the smart watch completes the detection and determines that it is worn normally, the detection result can be displayed on the interface 203: "It is currently worn normally, no adjustment is required."

[0062] Optionally, in some embodiments, the smart watch may further display a re-wearing detection control 204 on the interface 203. The smart watch detects that the user clicks the re-wearing detection control 204, and in response to the operation, the tightness of the smart watch can be detected again, and the detection result can be displayed on the interface 203 again.

[0063] For example, when the smart watch detects the tightness of the wearing for the first time and detects that it is worn too loose, it can output the detection result of wearing too loose. After seeing the detection result, the user can make corresponding adjustments. After the adjustment, the user does not need to return interface 203 to interface 201 and then click icon 202 in interface 201, but can directly click the re-wearing detection control 204 in interface 203 to trigger the wearing detection function of the smart watch.

[0064] It should be noted that the method for detecting the tightness of a smart watch is described below and will not be elaborated here.

[0065] In the embodiment of the present application, the smart watch can detect whether the user is wearing it normally, thereby ensuring the accuracy of functions such as blood pressure measurement, heart rate measurement, and blood oxygen measurement, which helps to improve the user experience.

[0066] Optionally, in some embodiments, when the smart watch determines that the wearing is too tight or too loose, adjustment prompt information can also be displayed.

[0067] For example, Figure 2 As shown in (e) in the figure, when the smart watch determines that the strap is worn too tight, it can display an adjustment prompt message: "Please loosen the strap a bit."

[0068] For example, Figure 2 As shown in (f) in the figure, when the smart watch determines that the strap is too loose, it can display an adjustment prompt message: "Please tighten the strap."

[0069] Understandably, Figure 2 (e) and (f) are only examples. The adjustment prompt information displayed by the smart watch is determined according to the tightness of the user's wearing and is not fixed.

[0070] In the embodiment of the present application, the smart watch can detect whether the user is wearing it normally. When it is determined that the user is wearing it too tightly or too loosely, it can output adjustment prompt information to prompt the user how to make adjustments, thereby ensuring the accuracy of blood pressure measurement, heart rate measurement, blood oxygen measurement and other functions, and helping to improve the user experience.

[0071] It should be noted that Figure 2In the example shown, the desktop 201 includes a control for triggering the wearing detection function, but this is not limited to the embodiments of the present application. In other embodiments of the present application, the interface or service card of the application may include a control for triggering the wearing detection function.

[0072] It should also be noted that the operation of triggering wearing detection in the embodiment of the present application not only includes the user clicking on the control used to trigger the wearing detection function, but also may include the user pressing the crown (for example, pressing the crown three times in a row), rotating the crown (for example, rotating the crown two turns), preset gestures, etc.

[0073] Figure 2 The GUI for wearing detection of a smart watch in response to a user triggering the wearing detection function is introduced. The following will introduce the GUI for wearing detection of a smart watch when performing physiological parameter measurements (for example, blood pressure measurement, heart rate measurement, etc.). The following will mainly introduce blood pressure measurement as an example.

[0074] Figure 3 Another set of GUIs provided by an embodiment of the present application is shown.

[0075] like Figure 3 As shown, the smart watch displays interface 301, which is a desktop. The smart watch displays an icon 302 on interface 301, which corresponds to the blood pressure measurement function. When the smart watch detects that the user clicks on icon 302, it can respond to the operation and perform blood pressure measurement. Before performing blood pressure measurement, the smart watch can first perform a wearing detection, and the smart watch can automatically trigger the wearing detection, that is, Figure 3 The GUI shown in FIG. 1 can also trigger wearing detection in response to a manual operation determined by the user, such as Figure 4 When it is determined that the fit is too loose, the following GUI may be displayed: Figure 3 The GUI shown in (b) in FIG. 1 may display the following information when it is determined that the wearing is too tight: Figure 3 The GUI shown in (c) in FIG. 1 can measure blood pressure and display the following when the wearer wears the device normally: Figure 3 GUI shown in (d).

[0076] like Figure 3 As shown in (b) in the figure, when the smart watch determines that the wearer is wearing the clothes too loosely, the detection result can be displayed on the interface 303: "The wearer is wearing the clothes too loosely at present. Please adjust the wearer's clothes in time before measuring the blood pressure again."

[0077] like Figure 3 As shown in (c) in the figure, when the smart watch determines that the wearer is wearing it too tight, the detection result can be displayed on the interface 303: "It is currently wearing it too tight, please adjust it in time before measuring your blood pressure."

[0078] like Figure 3As shown in (d) in FIG. 2 , when the smart watch determines that the wearing is normal, the blood pressure measurement can be performed and the blood pressure measurement result can be displayed on the interface 203 .

[0079] In the embodiment of the present application, the smart watch can detect whether the user is wearing it normally before measuring blood pressure, thereby ensuring the accuracy of the blood pressure measurement function and helping to improve the user experience.

[0080] Optionally, in some embodiments, when the smart watch determines that the wearing is too loose or too tight, a re-wearing detection control 304 may be displayed on the interface 303. The smart watch detects that the user clicks the re-wearing detection control 304, and in response to the operation, the wearing detection may be performed again.

[0081] Optionally, in some embodiments, when the smart watch determines that the wear is normal and the blood pressure measurement is completed, the smart watch can also display a blood pressure measurement control 305 on the interface 303. The smart watch detects that the user clicks the blood pressure measurement control 305 again, and in response to the operation, the blood pressure measurement can be performed again.

[0082] Optionally, in some embodiments, when the smart watch determines that the wearer is too tight or too loose, it can also display adjustment prompt information. It should be understood that the description of the smart watch displaying adjustment prompt information can refer to the description of Figure 2 The description of (e) and (f) in the figure is not repeated here for the sake of brevity.

[0083] In an embodiment of the present application, the smart watch can detect whether the user is wearing the watch properly before measuring blood pressure. When it is determined that the user is wearing the watch too tightly or too loosely, it can output adjustment prompt information to prompt the user how to adjust it, thereby ensuring the accuracy of blood pressure measurement and helping to improve the user experience.

[0084] Figure 3 In the GUI shown, the smart watch can automatically detect the tightness of the wearer before measuring the blood pressure. In other embodiments of the present application, the smart watch can determine whether to detect the tightness of the wearer before measuring the blood pressure according to the user's operation. Figure 4 Provide explanation.

[0085] Figure 4 Another set of GUIs provided by an embodiment of the present application is shown.

[0086] like Figure 4 As shown in (a) of FIG. 1 , the smart watch displays an interface 401, which may be a desktop. The smart watch displays an icon 402 on the interface 401, which corresponds to the blood pressure measurement function. When the smart watch detects that the user clicks the icon 402, it can respond to the operation by displaying the following: Figure 4 GUI shown in (b) in .

[0087] like Figure 4 As shown in (b), in response to the user clicking on icon 402, the smart watch can display an option box 403, which is used to output prompt information, and the prompt information is used to prompt the user whether to perform a wearing test. When the smart watch detects that the user clicks on the confirmation control 404, the wearing test can be performed first, and when it is determined that the wearing is normal, the blood pressure measurement can be performed. When the smart watch detects that the user clicks on the cancel control 405, the blood pressure measurement can be performed.

[0088] It is understandable that when the smart watch adjusts the wearing tightness in response to the user clicking the confirmed control 404, if it is detected that the wearing is too tight or too loose, similar to Figure 2 or Figure 3 As shown in the GUI, the smart watch can display the test results. For detailed description, please refer to the above text and will not be repeated here.

[0089] Figure 3 and Figure 4 The GUIs shown in the figure all perform wearing detection before blood pressure measurement. In other embodiments of the present application, the smart watch can also perform wearing detection after completing blood pressure measurement. Figure 5 Make an introduction.

[0090] Figure 5 Another set of GUIs provided by an embodiment of the present application is shown.

[0091] like Figure 5 As shown, the smart watch displays interface 501, which may be a desktop. The smart watch displays icon 502 on interface 501, which corresponds to the blood pressure measurement function. When the smart watch detects that the user clicks on icon 502, it can respond to the operation and display the following: Figure 5 GUI shown in (b) in .

[0092] like Figure 5 As shown in (b) in FIG. 5 , in response to the user clicking on icon 502 , the smart watch can measure blood pressure and display the blood pressure measurement result on interface 503 .

[0093] like Figure 5As shown in (c)-(d) in FIG. 1 , the smart watch can store the average value of the blood pressure measurement results over a period of time (e.g., one week), and can compare the difference between the average value and the blood pressure measurement result of this time. When the difference between the two is greater than a threshold, the smart watch can display an option box 504, which is used to output a prompt message, and the prompt message is used to prompt the user whether to perform a wearing test. When the smart watch detects that the user clicks the confirmation control 505, it can perform a wearing test, and after the test is completed, the test result is displayed on the interface 506: "The current wear is too loose, please adjust it in time before measuring blood pressure."

[0094] Optionally, in some embodiments, the smart watch may also display adjustment prompt information on interface 506 . Please refer to the above for the specific description, which will not be repeated here.

[0095] Optionally, in some embodiments, the smart watch may also display a re-wearing detection control 507 and / or a re-blood pressure measurement control 508 on the interface 506 . Please refer to the above for the specific description, which will not be repeated here.

[0096] In an embodiment of the present application, after completing the blood pressure measurement, the smart watch can compare the blood pressure measurement result with the previous blood pressure measurement result. If the difference is large, a wearing detection can be performed to prompt the user to make adjustments, which helps to improve the user experience.

[0097] The above describes several scenarios in which the method for detecting wearing a wearable device provided in the embodiment of the present application is applicable. The following describes the method for detecting wearing a wearable device provided in the embodiment of the present application.

[0098] Figure 6 FIG. 6 is a schematic flow chart of a wearable device wearing detection method 600 provided in an embodiment of the present application. Figure 6 As shown, the method includes:

[0099] S601, if it is detected that a preset condition is met, the airbag is inflated with gas.

[0100] Specifically, the wearable device can fill the airbag with gas when detecting that a preset condition is met, wherein the time for filling the gas is T seconds, T>0.

[0101] In some embodiments, detecting that a preset condition is satisfied is: detecting an operation by a user triggering wearing detection.

[0102] For example, Figure 2 As shown, the smart watch detects that the user clicks on icon 202, and icon 202 corresponds to the wearing detection function.

[0103] For example, Figure 2As shown, the smart watch detects that the user clicks the operation of wearing detection control 204 again.

[0104] For example, Figure 3 As shown, the smart watch detects that the user clicks the operation of wearing detection control 304 again.

[0105] For example, Figure 4 As shown, the option box 403 includes a confirmation control 404 and a cancel control 405. The option box 403 is used to output prompt information, and the prompt information is used to prompt the user whether to perform a wearing detection. The smart watch detects that the user clicks the confirmation control 404.

[0106] For another example, the smart watch detects that the user presses the crown three times in succession.

[0107] For another example, the smart watch detects that the user rotates the crown twice.

[0108] For another example, the smart watch detects a preset gesture of the user, and the preset gesture corresponds to the wearing detection function.

[0109] In some embodiments, the detection of satisfying a preset condition is: detecting that a user triggers an operation of measuring a physiological parameter, wherein the physiological parameter includes one or more of the following: blood pressure, heart rate, and blood oxygen.

[0110] For example, Figure 3 As shown, the smart watch detects that the user clicks on icon 302, and icon 302 corresponds to the blood pressure measurement function.

[0111] In some embodiments, the detection that the preset condition is satisfied is: detecting that the difference between the measured physiological parameter value and the average value of the physiological parameter values ​​measured in the first time period is greater than a threshold.

[0112] For example, Figure 5 As shown, when the smart watch detects that the difference between the blood pressure value measured this time and the average blood pressure value measured in the past week is greater than a threshold, wearing detection can be performed.

[0113] S602, detecting the volume expansion rate of the airbag within T seconds.

[0114] Specifically, when the wearable device fills the airbag with gas through an air pump, the volume expansion rate of the airbag can be detected to determine whether it is worn tight or not. The volume expansion rate can be understood as a parameter used to characterize the speed of airbag expansion. When the airbag expands quickly, the volume expansion rate of the airbag is large, and when the airbag expands slowly, the volume expansion rate of the airbag is small. When the airbag is not pressed against the user's skin, the volume expansion rate of the airbag may be constant. When the airbag begins to press against the user's skin, the volume expansion rate of the airbag begins to slow down due to the influence of the resistance from the user's skin. It is not difficult to understand that when the airbag is filled with gas at the same inflation rate, the tighter the wearable device is worn, the earlier the airbag is subjected to the resistance from the user's skin, and the smaller the volume expansion rate of the airbag. Therefore, the tightness of the wearable device can be judged by detecting the volume expansion rate of the airbag.

[0115] In some embodiments, since the air pump has a duty cycle when working, the airbag will deflate in the working gap of the air pump, and as the volume of the airbag increases, the resistance of the airbag from the skin will also increase, and the deflation rate of the airbag in the working gap of the air pump will also increase. It is not difficult to understand that at the same time, the tighter the wearable device is worn, the greater the resistance of the airbag from the skin, and the greater the deflation rate of the airbag in the working gap of the air pump. Therefore, the wearable device can determine the volume expansion rate of the airbag within T seconds according to formulas (1) and (2).

[0116]

[0117]

[0118] Among them, P0 is the pressure inside the airbag when the airbag is not inflated, P t is the pressure inside the airbag at time t when the airbag is inflated, W'(t) is the difference between the inflation rate and the deflation rate at time t, n'0 is the amount of gas, ε is the volume expansion rate of the airbag in T seconds, T is the time for inflating the airbag, and T>0.

[0119] W'(t) is determined based on the inflation rate and deflation rate at time t, where the inflation rate and deflation rate are quantities related to the air pump and airbag pressure. When the hardware specifications of the air pump are fixed, the inflation rate and deflation rate can be determined based on the duty cycle of the air pump and the pressure of the airbag.

[0120] For example, the inflation rate and deflation rate of the same air pump at different duty cycles and different airbag pressures can be experimentally measured, and the wearable device can then store the measurement results so that they can be used when calculating the volume expansion rate of the airbag.

[0121] It should be noted that the above formulas (1) and (2) are only examples and are not to be construed as limitations on the present application. The method for implementing the wearable device wearing detection provided in the embodiment of the present application by measuring the volume expansion rate of the airbag by other methods should also fall within the scope of protection of the present application.

[0122] S603: Determine a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds.

[0123] Specifically, after the wearable device determines the volume expansion rate of the airbag, it can determine the wearing detection result according to the relationship between the measured volume expansion rate and the first threshold.

[0124] In some embodiments, when the volume expansion rate is greater than a first threshold, it is determined that the fit is too loose.

[0125] For example, if the first threshold is 2 and the measured volume expansion rate is 5, it can be determined that the wearable device is worn too loosely.

[0126] In some embodiments, when the volume expansion rate is less than a second threshold, it is determined that the fit is too tight.

[0127] For example, if the second threshold is 1.5 and the measured volume expansion rate is 1.3, it can be determined that the wearable device is worn too tightly.

[0128] In some embodiments, when the volume expansion rate is greater than or equal to the second threshold and less than or equal to the first threshold, it is determined that the wearing is normal.

[0129] For example, if the first threshold is 2, the second threshold is 1.5, and the measured volume expansion rate is 1.8, it can be determined that the wearable device is worn normally.

[0130] S604, displaying a first interface, where the first interface includes a wearing detection result.

[0131] Specifically, after the wearable device determines the wearing detection result, the wearing detection result can be displayed on the first interface.

[0132] For example, Figure 2 As shown in (b) in FIG. 2 , the smart watch displays the wearing detection result on the interface 203 .

[0133] In the embodiment of the present application, the wearable device can determine whether the wearing is normal by detecting the volume expansion rate of the airbag, thereby ensuring the accuracy of the physiological parameter measurement results without adding hardware and increasing additional costs.

[0134] Since the air pump is affected by factory deviations, air path blockages caused during use, etc., there may be large deviations when the air pump inflates the airbag, which may cause inaccurate wearing test results.

[0135] For example, assuming that user #1 wears wearable device #1 normally, user #2 wears wearable device #2 normally, wearable device #1 is equipped with air pump #1, wearable device #2 is equipped with air pump #2, air pump #1 and air pump #2 are air pumps of the same model, air pump #1 has air path blockage, air pump #2 does not have air path blockage, air pump #1 and air pump #2 inflate airbag #1 and airbag #2 respectively with the same power. It is not difficult to understand that due to the air path blockage of air pump #1, the volume expansion rate of airbag #1 will be lower than the volume expansion rate of airbag #2, and may be lower than the second threshold, thereby resulting in a false judgment that user #1 is wearing it too tightly.

[0136] In summary, if Figure 7 As shown, in some embodiments of the present application, before executing S601, the method further includes:

[0137] S605, detecting the performance of the air pump, and determining a first weighted parameter according to the performance of the air pump.

[0138] Specifically, the wearable device can detect the performance of the air pump and determine the first weighted parameter according to the performance of the air pump.

[0139] S603, determining a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds, including:

[0140] S6031: Determine a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds and the first weighted parameter.

[0141] Specifically, the wearable device can determine the first weighted volume expansion rate of the airbag within T seconds based on the volume expansion rate of the airbag within T seconds and the first weighted parameter, and then determine the wearing detection result of the wearable device based on the first weighted volume expansion rate of the airbag within T seconds.

[0142] In some embodiments, the wearable device may determine a first weighted volume expansion rate of the airbag within T seconds according to formulas (3) and (4).

[0143]

[0144]

[0145] Among them, β t is the first weighted volume expansion rate of the airbag at time t, β is the first weighted volume expansion rate of the airbag within T seconds, and A is the first weighted parameter.

[0146] It can be understood that when the performance of the air pump is poor, the air pump corresponds to a larger first weighted parameter, and when the performance of the air pump is better, the air pump corresponds to a smaller first weighted parameter, thereby eliminating the inaccuracy of the wearing detection results caused by the differences between the performances of the various air pumps.

[0147] The method for detecting the performance of the air pump is not limited in the embodiments of the present application. The following are several possible methods for detecting the performance of the air pump.

[0148] One possible method is to fill the air bag with gas, and when the pressure of the air bag reaches a first pressure, perform a deflation process, and then determine the performance of the air pump according to the deflation rate.

[0149] Exemplarily, the deflation rate may be determined according to equations (5) and (6).

[0150]

[0151] P m V m =P0V0 (6)

[0152] Where v is the deflation rate, V m is the volume of the airbag when the pressure is the first pressure, P0 is the pressure inside the airbag when the airbag is not inflated, V0 is the volume of the airbag when the airbag is not inflated, P m is the first pressure, m is the pressure of the airbag, P m It is understood that since P0 and V0 are known, V can be determined by formula (5): m Then, the pressure of the airbag is detected by P m The time becomes P0, so the deflation rate can be calculated.

[0153] A possible method is that the air pump fills the airbag with gas at a first duty cycle, determines the filling time of the gas when the pressure of the airbag reaches a second pressure, and then determines the performance of the air pump based on the filling time, wherein the first duty cycle is greater than 0 and less than or equal to 100%.

[0154] It is understandable that when the filling time is short, the performance of the air pump is better, and when the filling time is long, the performance of the air pump is worse.

[0155] In the embodiment of the present application, the wearable device can first evaluate the performance of the air pump, and then determine whether the wearing is normal based on the performance of the air pump and the volume expansion rate of the airbag, thereby ensuring the accuracy of the physiological parameter measurement results without adding hardware and increasing additional costs.

[0156] In addition to the impact of air pump performance on the wearing test results, the user's wearing posture will also affect the wearing test results.

[0157] For example, taking the wearable device as a smart watch, suppose the smart watch is worn too loosely and the smart watch needs to be worn before measuring blood pressure. Because the smart watch requires the user to press the wrist against the chest when measuring blood pressure, this operation will cause the airbag to be squeezed, and the measured volume expansion rate of the airbag will become smaller, which may be misjudged as normal wearing.

[0158] In summary, if Figure 8 As shown, in some embodiments of the present application, before executing S601, the method further includes:

[0159] S606: Detect the wearing posture of the user, and determine a second weighting parameter according to the wearing posture of the user.

[0160] Specifically, the wearable device can detect the wearing posture of the user and determine the second weighted parameter according to the wearing posture.

[0161] For example, taking the wearable device as a smart watch, if the smart watch detects that the user presses the wrist against the chest, the second weighted parameter is 1.5; if the smart watch does not detect that the user presses the wrist against the chest, the second weighted parameter is 1.

[0162] For example, the wearable device can perform detection through an inertial measurement unit (IMU) and a microphone. When the wearable device detects the ups and downs of the user's wrist through the IMU and detects the heartbeat signal through the microphone, the wearable device can determine that the user is pressing his wrist against his chest.

[0163] S603, determining a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds, including:

[0164] S6032: Determine a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds and the second weighted parameter.

[0165] Specifically, the wearable device can determine the second weighted volume expansion rate of the airbag within T seconds based on the volume expansion rate of the airbag within T seconds and the second weighted parameter, and then determine the wearing detection result of the wearable device based on the second weighted volume expansion rate of the airbag within T seconds.

[0166] In some embodiments, the wearable device may determine the second weighted volume expansion rate of the airbag within T seconds according to formulas (7) and (8).

[0167]

[0168]

[0169] Among them, ωt is the second weighted volume expansion rate of the airbag at time t, ω is the second weighted volume expansion rate of the airbag within T seconds, and B is the second weighted parameter.

[0170] In the embodiment of the present application, the wearable device can first detect the user's wearing posture, and then determine whether the wearing is normal based on the user's wearing posture and the volume expansion rate of the airbag, thereby ensuring the accuracy of the physiological parameter measurement results without adding hardware and increasing additional costs.

[0171] Since both the air pump performance and the user's wearing posture will affect the wearing detection result, in some embodiments of the present application, the wearable device may first detect the user's wearing posture and the air pump performance.

[0172] like Fig. 9 As shown, before executing S601, the method further includes:

[0173] S605, detecting the performance of the air pump and determining a first weighted parameter according to the performance of the air pump

[0174] S606: Detect the wearing posture of the user, and determine a second weighting parameter according to the wearing posture of the user.

[0175] It should be understood that the embodiment of the present application does not limit the execution order of S605 and S606, that is, S605 and S606 can be executed simultaneously, S605 can be executed first and then S606, or S606 can be executed first and then S605.

[0176] S603, determining a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds, including:

[0177] S6033: Determine a wearing detection result of the wearable device according to the volume expansion rate of the airbag within T seconds, the first weighted parameter, and the second weighted parameter.

[0178] Specifically, the wearable device can determine a third weighted volume expansion rate based on the volume expansion rate of the airbag within T seconds, the first weighted parameter and the second weighted parameter, and then determine the wearing detection result of the wearable device based on the third weighted volume expansion rate of the airbag within T seconds.

[0179] In some embodiments, the wearable device may determine the third weighted volume expansion rate of the airbag within T seconds according to formulas (9) and (10).

[0180]

[0181]

[0182] Among them, δ tis the third weighted volume expansion rate of the airbag at time t, and δ is the third weighted volume expansion rate of the airbag within T seconds.

[0183] Optionally, in some embodiments, the method further comprises:

[0184] Determine and adjust the prompt information according to the volume expansion rate of the airbag within T seconds;

[0185] The adjustment prompt information is displayed on the first interface.

[0186] Exemplarily, Table 1 shows the corresponding relationship between the volume expansion rate and the adjustment prompt information.

[0187] Table 1 Correspondence between volume expansion rate and adjustment prompt information

[0188]

[0189]

[0190] For example, Figure 2 As shown in (e) in the figure, when the smart watch determines that the strap is worn too tight, an adjustment prompt message can be displayed on interface 203: "Please loosen the strap a bit."

[0191] In an embodiment of the present application, the wearable device can display adjustment prompt information based on the volume expansion rate. The adjustment prompt information can prompt the user how to adjust and the adjustment range, so that the user can adjust the tightness more accurately, ensuring the accuracy of the physiological parameter measurement results without adding hardware and adding additional costs.

[0192] It should be noted that in the above embodiments, the example of a wearable device that can detect both loose wearing and tight wearing is taken, but the embodiments of the present application are not limited thereto. In other embodiments, the wearable device can use the above method to only detect loose wearing, or can also only detect tight wearing. It is not difficult to understand that when the wearable device only detects loose wearing, or can also only detect tight wearing, only one threshold can be set to determine whether the wear is too loose or too tight.

[0193] For example, the threshold is set to a first threshold, and when the volume expansion rate is greater than the first threshold, it is determined that the wearing is too loose.

[0194] For another example, the threshold is set to a second threshold, and when the volume expansion rate is less than the second threshold, it is determined that the wearing is too tight.

[0195] The above mainly introduces a method for wearing detection of a wearable device provided in an embodiment of the present application from the perspective of a wearable device.

[0196] The embodiment of the present application can divide the processor in the wearable device into functional modules (or units) according to the above method example.
