[0002] Current smart watches can measure the user's electrocardiogram, heart rate, respiration, blood oxygen, blood pressure, body temperature and other physiological signals, specifically using electrodes or light-emitting diodes (LEDs) on the back of the dial body to measure physiological signals. When the back of the dial is in direct contact with the human body, the smart watch can detect the user's physiological signals using electrode signals or light signals.

[0003] When there is poor contact between the back of the dial and the user's skin, or when relative sliding occurs, it will affect the quality of the electrode signal or the optical signal, seriously affecting the accuracy of the measurement results. Summary of the invention

[0004] The embodiments of the present application provide a wearable device control method, a wearable device, and a storage medium, which can improve the accuracy of measuring physiological signals by wearable devices such as smart watches.

[0005] In a first aspect, a wearable device control method is provided, the method comprising: if a measurement instruction of a physiological signal is detected, determining a contact pressure value between the wearable device and a wearing part of the wearable device;

[0006] The tightness of the fixing part of the wearable device can also be adjusted according to the above contact pressure value and a preset pressure threshold, where the pressure threshold is a threshold of the contact pressure that ensures that the wearable device detects the physiological signal.

[0007] In the method provided in the first aspect of the embodiment of the present application, the contact pressure between the fixing part (such as a watch strap) of the wearable device and the wearing part can be detected, so that the watch strap can be adjusted according to the obtained contact pressure, which can prevent the watch strap from being too loose or too tight. By adjusting the tightness of the watch strap, the contact pressure between the wearing part and the wearable device is within a range suitable for measuring physiological signals, which can provide a good measurement environment, so that the wearable device can detect physiological signals with higher signal quality, reduce interference with optical signals or electrical signals, and improve the accuracy of the measurement results.

[0070] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0071] The wearable device may generally include a main body 1 and a fixing part 2. The main body 1 supports data interaction between the wearable device and other devices, supports interaction with the cloud, and can also provide a variety of software functions. The fixing part 2 is used to fix the wearable device. The wearable device may be a wearable watch, a wearable helmet, wearable glasses, etc. The embodiment of the present application does not limit the specific form of the wearable device.

[0072] Figure 1 Taking a smart watch type wearable device as an example, the main body 1 may be a dial, and the fixing part 2 may be a strap. When the smart watch is worn and contacts the wearing part, the smart watch can measure various physiological signals.

[0073] Specifically, Figure 2 This is a schematic diagram of the structure of a smart watch. Figure 2 The back of the smart watch dial is provided with electrodes 1, 2, a light emitting device 3 and a light detecting device 4. The light detecting device 4 may be a light emitting diode (LED).

[0074] In a possible implementation, when the physiological signal measurement function of the smart watch is activated, the light emitting device 3 can emit light of a specific wavelength to the skin, and the light reflected back through the skin tissue is received by the light detection device 4. The smart watch can also convert the optical signal received by the light detection device 4 into an electric signal, and then convert it into a digital signal through a digital-to-analog converter. According to the DC and AC signals extracted from the digital signal, the characteristics of blood flow are determined, thereby determining physiological signals, such as human electrocardiogram, heart rate, respiration, blood oxygen, blood pressure, body temperature, etc.

[0075] In another possible implementation, when the physiological signal measurement function of the smart watch is activated, electrodes 1 and 2 can measure the electrical signals generated by the human heart beat, and the smart watch can perform digital-to-analog conversion on the measured electrical signals to obtain digital signals. A signal graph similar to a traditional electrocardiogram can be extracted from the digital signals to determine information such as heart rate and electrocardiogram.

[0076] When there is poor contact between the smart watch and the wearing part, for example, the smart watch slips due to user movement, or the smart watch strap is too loose, it will affect the quality of the optical signal or electrical signal, seriously affecting the accuracy of the measurement results.

[0077] In view of the above problems, the embodiment of the present application provides a wearable device control method, which can detect the contact pressure between the fixing part (such as a watch strap) of the wearable device and the wearing part, so as to adjust the watch strap according to the obtained contact pressure, and avoid the watch strap being too loose or too tight. By adjusting the tightness of the watch strap, the contact pressure between the wearing part and the wearable device is within a range suitable for measuring physiological signals, which can provide a good measurement environment, reduce interference with optical signals or electrical signals, ensure that the wearable device can measure physiological signals of good quality, and improve the accuracy of the measurement results.

[0078] The present application embodiment provides a wearable device control method. Figure 3 , the method comprises the following steps:

[0079] Step 301: If a measurement instruction of a physiological signal is detected, a contact pressure value between the wearable device and a wearing part of the wearable device is determined.

[0080] When the function button for measuring physiological signals on the display interface of the wearable device is clicked, or the button for measuring physiological signals on the wearable device is clicked, the wearable device can detect the measurement instruction of the physiological signal. In the method provided in the embodiment of the present application, in order to avoid the influence of the measurement result of the physiological signal caused by the fixing part of the wearable device being too loose or too tight, after the wearable device detects the measurement instruction of the physiological signal, it will not measure the physiological signal immediately, but execute step 301 to determine the tightness of the wearable device.

[0081] In a possible implementation, the wearable device determines the tightness of the fixing part of the wearable device by detecting the contact pressure value between the fixing part of the wearable device and the wearing part. The contact pressure value is used to indicate the size of the contact pressure between the wearing part of the wearable device and the wearable device. The contact pressure can be the pressure caused by the wearing part (e.g., the user's wrist) on the wearable device after the wearable device is worn.

[0082] Specifically, the wearable device can detect the pressure value of the contact point between the wearable device and the wearing part, and determine the contact pressure value between the wearable device and the wearing part according to the pressure value detected at the contact point. Among them, the contact point is set on the wearable device for detecting the pressure between the wearable device and the wearing part. The contact point can be a pressure sensor. Of course, the contact point can also be other devices for detecting pressure, and the embodiments of the present application do not limit this. In addition, the embodiments of the present application do not specifically limit the position of the contact point on the wearable device, as long as it can detect the contact pressure value.

[0083] It should be noted that the wearing part in the embodiment of the present application can be the wrist, the neck, the ankle, or the head wearing area, and this embodiment does not specifically limit the wearing part.

[0084] Step 302: adjusting the tightness of the wearable device fixing part according to the contact pressure value and a preset pressure threshold, where the pressure threshold is a threshold of the contact pressure that ensures that the wearable device detects the physiological signal.

[0085] It should be noted that the fixings of the wearable device (for example, the strap of a smart watch) should not be too loose when measuring physiological signals. This is because when the fixings of the wearable device are too loose, too many interference signals will be introduced, which will interfere with the optical signals or electrical signals used to measure physiological signals, seriously affecting the accuracy of the measurement results. Of course, the fixings of the wearable device should not be too tight when measuring physiological signals. This is because when the fixings of the wearable device are too tight, it will have a certain impact on the physiological state of the wearing part, and may also affect the accuracy of the measurement results. For example, when the fixings of the wearable device are too tight, it affects the measurement of heart rate.

[0086] That is to say, in order to more accurately measure physiological signals, the tightness of the fixing parts of the wearable device should be within a reasonable range to provide a good measurement environment. When the tightness of the fixing parts is within a reasonable range, the contact pressure between the wearing part and the wearable device is also within a reasonable range.

[0087] In an embodiment of the present application, the pressure threshold can be used to characterize the reasonable range of the contact pressure between the wearable device and the wearing part when the tightness of the fixing part of the wearable device is within a reasonable range. For example, the pressure threshold can be a threshold of the contact pressure that ensures that the wearable device detects the physiological signal. When the contact pressure between the wearable device and the wearing part is within the range indicated by the pressure threshold, the wearable device can measure the physiological signal normally, that is, the wearable device measures the physiological signal in a good measurement environment.

[0088] In one possible implementation, the pressure threshold includes a threshold (Fthres). For example, the pressure threshold is F0. If the currently detected contact pressure is greater than F0, it indicates that the fixing of the wearable device is too tight, and the wearable device can loosen the fixing to reduce the contact pressure between the wearable device and the wearing part. If the currently detected contact pressure is less than F0, it indicates that the fixing of the wearable device is too loose, and the wearable device can tighten the fixing to increase the contact pressure between the wearable device and the wearing part. If the currently detected contact pressure is equal to F0, it indicates that the tightness of the fixing of the wearable device is appropriate, and the tightness of the fixing can be left unchanged.

[0089] In another possible implementation, the pressure threshold includes two thresholds. For example, the pressure threshold includes a first threshold (Fthres 1) and a second threshold (Fthres 2). The first threshold may be less than the second threshold, the first threshold is the minimum contact pressure value to ensure that the wearable device detects the physiological signal, and the second threshold is the maximum contact pressure value to ensure that the wearable device detects the physiological signal. When the first threshold is equal to the second threshold, that is, the pressure threshold includes a threshold, the specific judgment process refers to the previous text and will not be repeated here.

[0090] If the contact pressure value currently detected by the wearable device is less than the first threshold, it indicates that the fixing of the wearable device is too loose, and the wearable device can tighten the fixing to increase the contact pressure between the wearable device and the wearing part. If the contact pressure value currently detected by the wearable device is greater than the first threshold, it indicates that the fixing of the wearable device is too tight, and the wearable device can fix the fixing in a different way to reduce the contact pressure between the wearable device and the wearing part. If the contact pressure value currently detected by the wearable device is greater than or equal to the first threshold, and less than or equal to the second threshold, it indicates that the tightness of the fixing of the wearable device is appropriate, and the tightness of the fixing may not be adjusted.

[0091] Embodiments of the present application Figure 3 In the wearable device control method provided, when a measurement instruction of a physiological signal is detected, the contact pressure value between the wearable device and the wearing part of the wearable device can be determined, and then the tightness of the fixing part of the wearable device can be adjusted according to the contact pressure value and a preset pressure threshold, so that the contact pressure between the wearable device and the wearing part is handled within a reasonable range, providing a good measurement environment, reducing the interference of the external environment on the measurement signal (for example, an electrical signal or an optical signal), ensuring that the wearable device can measure a physiological signal of good quality, thereby improving the accuracy of the measurement result.

[0092] Embodiments of the present application Figure 3 The specific implementation process of "determining the contact pressure value between the wearable device and the wearing part of the wearable device" in the method shown includes: one or more contact points on the wearable device can detect the pressure between the wearable device and the wearing part to obtain one or more pressure values. Further, the wearable device can also determine the contact pressure value between the wearable device and the wearing part of the wearable device based on the measured one or more pressure values.

[0093] For example, the wearable device detects the pressure between the wearing part and N contact points to obtain N pressure values; the wearable device can also determine the contact pressure value according to the N pressure values, where N is an integer greater than or equal to 1.

[0094] In a specific implementation, the N pressure values ​​may be weighted and summed to obtain the above contact pressure value. Specifically, the following two possibilities may be included:

[0095] The first type is that the weighting coefficients corresponding to the N pressure values ​​are the same, that is, the wearable device calculates the average value of the N pressure values ​​and uses the average value as the contact pressure value.

[0096] For example, there are three contact points on the wearable device, including contact point 1 and contact point 2 on the wearable device body, and contact point 3 on the wearable device fixture. The pressure values ​​detected at contact point 1, contact point 2, and contact point 3 are F1, F2, and F3 respectively. The contact pressure value can be the average value of F1, F2, and F3, that is, (F1+F2+F3) / 3.

[0097] The first type is that the weighting coefficients corresponding to the N pressure values ​​are different.

[0098] For example, the weight coefficients of F1, F2, and F3 mentioned above are different. In one possible implementation, the weight coefficient corresponding to the contact point on the wearable device body is greater than the weight coefficient corresponding to the contact point on the wearable device fixture. For example, the weight coefficients corresponding to F1, F2, and F3 are a, b, and c, where a, b, and c are values ​​greater than 0 and less than 1, and a and b are both greater than 1. For example, a=b=0.4, c=0.2, then the contact pressure value=0.4*F1+0.4*F2+0.2*F3. Among them, "*" represents a multiplication operation.

[0099] It should be noted that the method for calculating the contact pressure value based on the pressure values ​​corresponding to multiple contact points is not limited to the method described above. The contact pressure value can also be calculated by other methods as long as it can characterize the pressure between the wearable device and the wearing part. The embodiments of the present application do not limit this.

[0100] In the method provided in the embodiment of the present application, the pressure value between the wearable device and the wearing part can be detected by using the contact points on the wearable device, so as to determine the contact pressure between the wearable device and the wearing part according to the detected pressure value, thereby providing a basis for reasonably adjusting the tightness of the fixing parts of the wearable device.

[0101] Embodiments of the present application Figure 3 The specific implementation process of adjusting the tightness of the fixing of the wearable device according to the contact pressure value and the preset pressure threshold includes: when the contact pressure value between the fixing and the wearing part is too large, loosening the fixing of the wearable device; when the contact pressure value between the fixing and the wearing part is too small, tightening the fixing of the wearable device.

[0102] For example, when the contact pressure value is less than a first threshold, the fixing part of the wearable device is tightened; when the contact pressure value is greater than a second threshold, the fixing part of the wearable device is loosened.

[0103] In the wearable device control method provided in the embodiment of the present application, after adjusting the tightness of the fixing member, the wearable device can further detect the contact pressure value to determine whether the contact pressure value after adjusting the tightness of the fixing member is within a reasonable range. Figure 4 As shown, Figure 3 The method shown also includes step 303 and step 304:

[0104] Step 303: Update the contact pressure value between the wearable device and the wearing part according to the current tightness of the fixing part of the wearable device.

[0105] It should be noted that after executing step 302, the contact pressure between the fixing part of the wearable device and the wearing part also changes due to the change in tightness of the fixing part of the wearable device. The wearable device can also update the contact pressure value between the wearable device and the wearing part according to the current tightness of the fixing part of the wearable device, that is, determine the current contact pressure value to determine whether the current contact pressure value is within a reasonable range that can ensure that the wearable device detects the physiological signal.

[0106] In a possible implementation, executing step 303 may be executing "determining the contact pressure value between the device on the passenger ship and the wearing location of the wearable device" in step 301 to determine the current contact pressure value.

[0107] Step 304: When the updated contact pressure value matches the preset pressure threshold, the physiological signal is measured.

[0108] Specifically, if the current contact pressure value matches the preset pressure threshold, it indicates whether the current contact pressure value is within a reasonable range that can ensure that the wearable device can detect the physiological signal, and a good measurement environment can be provided, and the wearable device performs physiological signal measurement.

[0109] In a specific implementation, the wearable device can emit light of a specific wavelength and receive light signals reflected back through the skin tissue of the wearing part. The received light signals are processed to determine physiological signals. Alternatively, the wearable device can use electrodes to measure the electrical signals generated by the heart beat of the wearing object (e.g., human body), and the measured electrical signals are processed to determine physiological signals.

[0110] It should be noted that the measurement of physiological signals by the wearable device includes but is not limited to the methods described above, and the physiological signals of the wearer of the wearable device can also be measured by other measurement methods, which is not limited in the embodiments of the present application.

[0111] Figure 4 In the method shown, after adjusting the tightness of the fixing part, the wearable device can also re-detect the contact pressure value between the wearable device and the wearing part, that is, determine the current contact pressure value, to determine whether the current contact pressure value is within a reasonable range that can ensure that the wearable device can detect the physiological signal, thereby ensuring that the wearable device can subsequently measure the physiological signal in a good measurement environment.

[0112] In the wearable device control method provided in the embodiment of the present application, the wearable device may also indicate to adjust the wearable device to a balanced state before adjusting the tightness of the fixing member. Figure 5 As shown, Figure 3 The method shown also includes step 301a and step 301b:

[0113] Step 301a: Determine the wearing state according to the pressure value corresponding to the first contact point and the pressure value corresponding to the second contact point.

[0114] It should be noted that before the wearable device performs tightness adjustment of the fixing member, the wearing state of the device can also be monitored, wherein the wearing state of the device can include a balanced wearing state and an unbalanced wearing state.

[0115] Specifically, it is possible to determine whether the wearable device is in a balanced wearing state based on the pressure values ​​detected by two contact points symmetrically set on the wearable device. For example, the pressure values ​​corresponding to the first contact point and the second contact point symmetrically set on the wearable device are used to determine whether the wearable device is in a balanced wearing state. The pressure value corresponding to the first contact point may be the pressure value detected at the first contact point, and the pressure value corresponding to the second contact point may be the pressure value detected at the second contact point.

[0116] In a specific implementation, taking a wearable watch as an example, the first contact point and the second contact point are symmetrically arranged on the side of the dial of the wearable watch facing the wearing part (e.g., the user's wrist), for example, the pressure sensor is symmetrically arranged on the back of the dial of the wearable watch. Alternatively, the first contact point and the second contact point are symmetrically arranged on the side of the wearable watch band that fits the wearing part.

[0117] Among them, the symmetrical arrangement of the first contact point and the second contact point can be considered to mean that the first contact point, the second contact point are at the same distance from the center line of the wearable device body. For example, the first contact point, the second contact point are at the same distance from the center line of the dial of the wearable watch.

[0118] The wearable device can determine whether the wearable device is in a balanced wearing state according to the pressure value corresponding to the first contact point and the pressure value corresponding to the second contact point, including: if the difference between the pressure value corresponding to the first contact point and the pressure value corresponding to the second contact point is less than or equal to a preset threshold, it can be determined that the wearable device is in a balanced wearing state. On the contrary, if the difference between the pressure value corresponding to the first contact point and the pressure value corresponding to the second contact point is greater than the preset threshold, it can be determined that the wearable device is in an unbalanced wearing state.

[0119] Step 301b: determine whether to output prompt information according to the wearing state; the prompt information is used to instruct the wearable device to be adjusted to a balanced wearing state.

[0120] Specifically, when the wearable device determines that it is currently in an unbalanced wearing state, it outputs a prompt message to prompt the wearer to adjust the wearing state of the wearable device. The prompt message may be a voice message, or a text message displayed on the device display interface, or a graphic displayed on the device display interface, which is not limited in the present embodiment of the application.

[0121] Figure 5 In the provided method, the wearable device can prompt to adjust the device to a balanced wearing state. When the wearable device is in a balanced wearing state, the wearable device body is in uniform contact with the skin of the wearing part. Under this premise, the measurement of physiological signals can obtain more accurate measurement results.

[0122] Optionally, after step 301b, the wearable device may also update the contact pressure value between the wearable device and the contact part according to the current wearing state, so as to adjust the tightness of the fixing part of the wearable device according to the updated contact pressure value. For example, after step 301b, the operation of determining the contact pressure between the wearable device and the wearing part in step 301 may also be performed. Specifically, the N contact points set on the wearable device may detect the pressure value between the wearable device and the contact part again, and determine the current contact pressure value according to the detected N pressure values.

[0123] The embodiment of the present application also provides a wearable device control method, which can prevent the wearable device from affecting the measurement result due to the looseness of the fixing part. Figure 6 As shown, the method comprises the following steps:

[0124] 601. The wearable device detects an instruction to measure a physiological signal.

[0125] The instruction for measuring the physiological signal may be an instruction for measuring an electrocardiogram (ECG) signal or an instruction for measuring a photoplethysmography (PPG) signal.

[0126] 602. The wearable device determines a contact pressure value between the wearable device and the wearing part.

[0127] Specifically, a contact point (eg, a pressure sensor) provided on the wearable device begins to measure a pressure value between the wearable device and the wearing part, and determines a contact pressure value between the wearable device and the wearing part according to the measured pressure value.

[0128] 603. The wearable device determines whether the contact pressure value is less than a pressure threshold.

[0129] Taking a pressure threshold as an example, the wearable device can determine whether the contact pressure value is less than the pressure threshold, that is, determine whether the fixing part of the wearable device is too loose to provide a good measurement environment.

[0130] If the current contact pressure value is less than the pressure threshold, step 604 is executed; if the current contact pressure value is greater than or equal to the pressure threshold, step 605 is executed.

[0131] 604. Tighten the fixing part of the wearable device.

[0132] In a specific implementation, the wearable device can instruct the adjustment component of the wearable device to tighten the fixing part of the wearable device to increase the contact pressure between the wearable device and the contact part, reduce the interference of the external environment on the physiological signal (for example, ECG signal or PPG signal), and improve the measurement accuracy of the wearable device.

[0133] It should be noted that the reference Figure 6 After executing step 604, steps 602 to 603 may be executed to detect the current contact pressure value. If the current contact pressure value is greater than the pressure threshold, step 605 is executed. If the current contact pressure value is still less than the pressure threshold, step 604 is executed again to tighten the fixing of the wearable device until the contact pressure value between the wearable device and the wearing part is greater than or equal to the pressure threshold.

[0134] 605. Measure physiological signals.

[0135] Figure 6 In the provided method, by detecting the contact pressure between the wearable device and the wearing part, it is identified whether the wearable device is worn too loose. If it is determined that the wearable device is worn too loose, the fixing part of the wearable device is tightened to increase the contact pressure between the wearable device and the contact part, reduce the interference of the external environment on the physiological signal (for example, ECG signal or PPG signal), and improve the measurement accuracy of the wearable device.

[0136] The present application embodiment provides a wearable device, such as Figure 7As shown, the wearable device includes: a main body 1 and a fixing part 2. Specifically, the main body 1 includes a measuring part 10. The measuring part 10 is used to transmit or receive a measurement signal. The measuring part 10 may include an electrode, an electrode, a light-emitting device, and a light-detecting device. N contact points are arranged on the fixing part 2, and the N contact points are arranged on a side of the main body 1 facing the wearing part. Alternatively, the N contact points are arranged on a side of the fixing part 2 that is in contact with the wearing part.

[0137] refer to Figure 7 The wearable device further includes an adjusting component 3. The adjusting component 3 is coupled to the fixing member 2, and the tightness of the fixing member 2 can be adjusted by rotating the adjusting component 3. In a possible implementation, the adjusting component 3 can be arranged at a location where the fixing member 2 is connected to the main body 1.

[0138] In a possible implementation, the contact points of the wearable device are symmetrically arranged. Figure 7 Two pressure detection points are used as an example, namely contact point 20 and contact point 21. Figure 7 The contact points 20 and 21 are symmetrically arranged, and the distances between the contact points 20 and 21 and the center line of the main body 1 are the same. In a possible implementation, the contact points 20 and 21 can also be symmetrically arranged on the back of the main body 1.

[0139] In one possible implementation, the contact point included in the wearable device is a pressure sensor. Taking the wearable device as a wearable watch (e.g., a smart watch in an embodiment of the present application) as an example, the pressure sensor is arranged on the side of the dial of the wearable watch facing the wearing part, for example, the pressure sensor is arranged on the back of the dial of the wearable watch. Alternatively, the pressure sensor is arranged on the side where the strap of the wearable device fits the wearing part.

[0140] Figure 8 is a possible implementation of the adjustment component 3. Figure 8 The adjusting component 3 includes a braking component 30 and a coupling component 31. The coupling component 31 is coupled to the fixing component 2, and the braking component 30 is used to control the coupling component to rotate in a loosening direction or a tightening direction according to the instruction of the main body 1. The tightening direction is the direction of shortening the fixing component 2, and the loosening direction is the direction of extending the fixing component 2.

[0141] In a possible implementation, the braking component 30 may be a driving motor, and the coupling component 31 may be a gear.

[0142] by Figure 7The wearable device shown is used as an example. When the physiological signal measurement button or the physiological signal measurement function button is triggered, the main body 1 of the wearable device can detect the instruction to measure the physiological signal. Further, the main body 1 obtains the pressure value F0 currently detected by the contact point 20 from the contact point 20, and obtains the pressure value F1 currently detected by the contact point 21 from the contact point 21.

[0143] The main body 1 can determine the contact pressure value F according to F0 and F1 * , according to the contact pressure value F * Determine whether to adjust the tightness of the fixing member 2. For example, add F0 and F1 and calculate the average value to obtain the contact pressure value F * Taking the pressure threshold including the first threshold and the second threshold mentioned above as an example, if the contact pressure value F * If the contact pressure value F is less than the first threshold, the main body 1 sends a signal to the adjustment component 3 to instruct the adjustment component 3 to tighten the fixing member 2 to increase the contact pressure between the wearable device and the wearing part. * If the contact pressure value F is greater than the second threshold, the main body 1 sends a signal to the adjustment component 3, instructing the adjustment component 3 to loosen the fixing member 2 to reduce the contact pressure between the wearable device and the wearing part. * If the pressure is between the first threshold and the second threshold, it indicates that the contact pressure between the wearable device and the wearing part is within a reasonable range and is suitable for measuring physiological signals, then the tightness of the fixing device does not need to be adjusted.

[0144] Specifically, when the contact pressure value F * When the torque is less than the first threshold, the main body 1 sends a signal 1 to the drive motor 30, instructing the drive motor 30 to rotate counterclockwise (i.e., a tightening direction provided in the embodiment of the present application) to drive the gear 31 to rotate counterclockwise, thereby tightening the fixing member 2 (for example, Figure 7 The contact pressure between the wearable device and the wearing part is increased. When the contact pressure value F * When the pressure difference is greater than the second threshold, the main body 1 sends a signal 2 to the drive motor 30, instructing the drive motor 30 to rotate clockwise (i.e., a loosening direction provided in an embodiment of the present application) to drive the gear 31 to rotate clockwise, thereby loosening the fixing part 2 and reducing the contact pressure between the wearable device and the wearing part.

[0145] After adjusting the tightness of the fixing 2, the contact pressure between the wearable device and the wearing part is within a reasonable range, which can provide a good measurement environment. The main body 1 can measure physiological signals.

[0146] Optionally, before the subject 1 measures the physiological signal, the subject 1 may also determine whether the wearable device is in a balanced wearing state based on the pressure values ​​detected by the two symmetrically arranged contact points. For example, whether the wearable device is in a balanced wearing state is determined based on the pressure values ​​F0 and F1 detected by the contact points 20 and 21. Specifically, if |F0-F1| is less than or equal to a preset threshold, it indicates that the wearable device is in a balanced wearing state; if |F0-F1| is greater than a preset threshold, it indicates that the wearable device is in an unbalanced wearing state. Wherein "||" is an absolute value operation.

[0147] When the main body 1 determines that the wearable device is not in a balanced wearing state, it outputs a prompt message to prompt the wearer to adjust the wearing state of the wearable device. The specific implementation of the prompt message is as described above, and the embodiment of the present application does not limit this.

[0148] refer to Fig. 9 Taking a wearable watch as an example, the prompt information may be a prompt interface. When the smart watch detects that the smart watch is in an unbalanced wearing state, an "arrow" is displayed on the display interface of the wearable device, and the smart watch is adjusted in a specified direction in combination with the text prompt displayed on the interface, so that the smart watch is in a balanced wearing state.

[0149] It should be noted that after adjusting the wearing state of the wearable device according to the prompt information output by the wearable device, the wearable device can detect the wearing state again. When it is detected that the wearable device is in a balanced wearing state, the physiological signal is measured.

[0150] It should be understood that although Figure 3 to Figure 6 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 3 to Figure 6 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
