According to various embodiments, the stable state may be determined based on motion data of the electronic device 101 provided from the motion sensor 403 and/or the biosignal provided from the PPG sensor 405 . For example, the processor 120 may acquire acceleration data from the motion sensor 403 (eg, at least one inertial sensor), and maintain the magnitude of the acceleration of the electronic device 101 below a predetermined magnitude (eg, : If it is confirmed that the state less than a certain size lasts more than a threshold time), the user can confirm that it is in a stable state. For example, the processor 120 may obtain a bio-signal from the PPG sensor 405, and based on the obtained bio-signal, the user's heart rate (HR) and/or stress is within a certain range (eg, : less than a certain value), it can be confirmed that the user is in a stable state. According to various embodiments, the processor 120 may confirm that the user is in a stable state based on the combination of the above-described motion data and biosignals. According to various embodiments, when it is confirmed that the user is in a stable state, the processor 120 may measure the user's blood pressure. This is because it is difficult to determine whether the user has high blood pressure disease or whether a high blood pressure value is measured because the user has a high blood pressure disease, even if it is confirmed that the measured blood pressure value is higher than a certain value if the user performed vigorous exercise before blood pressure measurement. . Alternatively, if the user is exercising vigorously, a dynamic noise (motion artifact) is generated in the blood pressure measurement process, or the light reflected by the PPG sensor 405 due to the electronic device 101 not being sufficiently in close contact with the user's body. This is because, in addition, noise may be received together, and blood pressure measurement may be inaccurate. Alternatively, the blood pressure ejected from the heart may not be uniform or the sympathetic nerve and/or the parasympathetic nerve may become unstable, so that the blood pressure measurement result may be inaccurate.

According to various embodiments, the processor 120 may measure the user's blood pressure using the PPG sensor 405 . For example, the processor 120 may receive a biosignal (eg, a biosignal in digital form) output and provided by the PPG sensor 405 , and measure the user's blood pressure based on the received biosignal. have. For example, the processor 120 may measure the user's blood pressure based on a pulse wave analysis (PWA) method. The blood pressure measurement method based on the PWA method may be a method of estimating blood pressure based on a waveform characteristic and/or a waveform pattern of the biosignal output from the PPG sensor 405 . The biosignal output from the PPG sensor 405 may include a direct current (DC) component having a constant value and an alternating current (AC) component having a varying magnitude. Here, the AC component may indicate a degree to which at least a portion of the light emitted from the light emitting unit of the PPG sensor 405 is absorbed, reflected, and/or scattered by the user's body. More specifically, at least a part of the emitted light is absorbed in bones, tissues, blood vessels, etc. of the user's body, and the rest is reflected and/or scattered. There may be a difference in the degree of absorption of light at a specific wavelength depending on the degree, hemoglobin, melanin, and the like. Accordingly, the AC component may represent a waveform having a feature point based on the difference in the degree of light absorption. The processor 120 may estimate the user's blood pressure based on the characteristics of the waveform, such as a peak, a valley, a second ^peak , and a delay of the above-described AC component. have. According to an embodiment, the processor 120 is, based on the characteristics and/or pattern of the waveform of the biosignal output and provided by the PPG sensor 405, a cardiac output (CO) value and/or total peripheral A total peripheral resistance value may be checked, and blood pressure variability (BPV) may be estimated based on a cardiac output value and/or a total peripheral resistance value. As another example, the processor 120 may measure the user's blood pressure based on the PWV method. The processor 120 may use the ECG sensor to determine when the user's blood is ejected from the heart, and use the PPG sensor 405 to determine when the blood arrives at the wearing part (eg, hand). Also, based on the difference between the time when the blood is ejected from the heart and the time when the blood arrives at the wearing part, the speed of the pulse wave may be calculated. Meanwhile, the processor 120 may measure the user's ballistocardiogram (BCG) to calculate the speed of the pulse wave. The processor 120 may estimate the user's blood pressure by checking the stored blood pressure value mapped to correspond to the calculated speed. According to various embodiments, the processor 120 may obtain a plurality of blood pressure values by repeatedly measuring the user's blood pressure a plurality of times or by measuring the user's blood pressure a plurality of times in a preset cycle. The processor 120 may calculate an average value of a plurality of acquired blood pressure values and/or select any one value as a representative value, and estimate it as the user's blood pressure. According to an embodiment, the processor 120 may determine the user's heart rate (or pulse rate), blood oxygen saturation and / or data on stress may be obtained.

According to various embodiments, the processor 120 may calibrate the measured blood pressure value based on the user's posture when measuring the blood pressure. For example, the processor 120 corrects the measured blood pressure value based on the difference between the height of the user's heart and the height at which the electronic device 101 is worn based on the user's posture, and the corrected blood pressure value can also be checked as the user's blood pressure.

According to various embodiments, the processor 120 measures the user's blood pressure and calculates it in the form of various parameters related to blood pressure, such as systolic blood pressure (SBP), diastolic blood pressure (DBP), or mean arterial pressure (MAP). And by estimation, the user's biometric information (eg, blood pressure data) may be obtained and provided to the user. For example, biometric information (eg, blood pressure data) may be output through various output devices such as the display 401 or a speaker (eg, the sound output module 155 of FIG. 1 ).

According to various embodiments, the memory 130 may store various data or information sensed, obtained, and/or confirmed of the present disclosure.

According to various embodiments, the display 401 may display the user's biometric information in the form of text and/or images. For example, the displayed biometric information may include information on heart rate (or pulse rate), blood oxygen saturation, stress, and/or blood pressure. According to various embodiments, the display 401 may display guide information based on the user's biometric information in the form of text and/or images.

Although not shown, the electronic device 101 may include a battery (eg, the battery 189 of FIG. 1 ) and/or various user interfaces (eg, a touch screen or a microphone). Although not shown, the electronic device 101 may include a communication module (eg, the communication module 190 of FIG. 1 ), and a server (eg, the server 108 of FIG. 1 ) and/or an external electronic device ( Example: The user's biometric information may be transmitted to the

electronic devices

102 and 104 of FIG. 1 ) by wire and/or wirelessly.

5 illustrates an electronic device (eg, the electronic device 101 of FIG. 1 ) measuring a user's blood pressure (eg, a wearer's blood pressure) based on a user's posture (eg, a wearer's posture), according to various embodiments of the present disclosure; It is a flowchart 500 for explaining a measuring method.

According to various embodiments, in operation 510 , the electronic device 101 may detect a user's posture using at least one motion sensor (eg, the motion sensor 403 of FIG. 4 ). For example, the electronic device 101 may, based on motion data acquired from at least one motion sensor (eg, the motion sensor 403 ), a posture of the user's body, a posture of a wearing part, and/or a movement of a wearing part. A pattern may be identified, and a user posture may be identified based on at least one of them.

According to various embodiments, in operation 530 , the electronic device 101 may check the number and/or duration of the user's posture (eg, a time at which the user's posture is sensed). For example, the number of user postures may be counted when it is confirmed that the user posture continues for a predetermined time or longer. According to various embodiments, the electronic device 101 may identify the frequency of the detected user postures based on the number and/or duration of the user postures. According to various embodiments, the electronic device 101 performs a frequency rank of the detected user postures based on the histories of the plurality of user postures (eg, the detected number of times, the sensed duration, and/or the frequency). ) can also be checked.

According to various embodiments, in operation 550 , the electronic device 101 performs at least one motion sensor 403 and/or at least one PPG sensor ( Example: Using the PPG sensor 405 of FIG. 4 ), it is possible to check whether the user is in a stable state. According to various embodiments, the electronic device 101 determines whether the detected user posture corresponds to a frequent posture (eg, a candidate posture for blood pressure measurement) based on the number and/or duration of the confirmed user posture. can be checked. According to various embodiments, when it is confirmed that the detected posture corresponds to a frequent posture (eg, a candidate posture for blood pressure measurement), the electronic device 101 determines that the user's physical and/or mental state is in a stable state (eg, It is possible to check whether the condition is suitable for blood pressure measurement). According to various embodiments of the present disclosure, the electronic device 101 , based on the motion data obtained from the at least one motion sensor 403 and/or the biosignal obtained from the at least one PPG sensor 405 , may and/or whether the mental state is a stable state (eg, a state suitable for blood pressure measurement). For example, the electronic device 101 detects a user's posture corresponding to the user's frequent posture using at least one motion sensor (eg, the motion sensor 403 ), and then sets the detected frequent posture to a threshold value. If it is confirmed that the period of time (eg, 30 seconds) or more or the state in which the magnitude of the acceleration of the electronic device 101 is less than a predetermined magnitude continues for more than a threshold time (eg, 5 minutes), it may be confirmed that the user is in a stable state. For example, the electronic device 101 obtains a user's biosignal using at least one PPG sensor (eg, the PPG sensor 405 ), so that the user's heartbeat and/or stress is within a certain range (eg, : less than a certain value) (or it is confirmed that the heart rate and/or stress is maintained below a certain value for a critical time (eg, 5 minutes) or more), the user may be confirmed to be in a stable state. According to an embodiment, the electronic device 101 may perform the operation 570 to be described later after performing the operation of determining whether the user is in a stable state a plurality of times (eg, twice). According to an embodiment, the electronic device 101 measures the user's heart rate first, and when it is confirmed that the user is in a resting state, measures the user's stress and when it is confirmed that the stress level is less than a predetermined value, the electronic device ( 101), if it is determined that the magnitude of the acceleration is less than a predetermined magnitude by measuring the magnitude of the acceleration, operation 570, which will be described later, may be performed. According to an embodiment, the electronic device 101 may measure the user's blood pressure at a preset cycle irrespective of operations 510 to 550 described above, and when the user's frequent posture is sensed, at least one It is also possible to adjust parameters (eg, the interval, time period, and/or number of repetitions for measuring blood pressure). For example, when the user's frequent posture is sensed, the electronic device 101 may decrease the blood pressure measurement period, lengthen the blood pressure measurement period, and/or increase the number of repetitions. As an example, the electronic device 101, based on that the detected user's posture corresponds to a frequent posture, according to at least one parameter (eg, period, period, and/or number of repetitions) mapped to the corresponding frequent posture, It can also measure the user's blood pressure.

According to various embodiments, in operation 570 , when it is confirmed that the user is in a stable state, the electronic device 101 may measure the user's blood pressure using at least one PPG sensor 405 . For example, the electronic device 101 may measure the user's blood pressure based on the PWA method and/or the PWV method. According to various embodiments, the electronic device 101 does not measure the user's blood pressure if it is not confirmed that the user is in a stable state after the user's frequent posture is detected, or if the user's blood pressure is being measured Blood pressure measurement can be stopped. For example, the electronic device 101 may measure the user's blood pressure at a preset period (eg, 1 hour) regardless of operations 510 to 550 described above, and when it is confirmed that the user is not in a stable state, the user Blood pressure measurement may be discontinued.

7 is a flowchart 700 for explaining a method of determining, by an electronic device (eg, the electronic device 101 of FIG. 1 ), a candidate posture for blood pressure measurement, according to various embodiments of the present disclosure.

According to various embodiments, in operation 710 , the electronic device 101 may learn a plurality of user postures using at least one motion sensor (eg, the motion sensor 403 of FIG. 4 ). For example, the electronic device 101 identifies at least one posture element based on motion data obtained from at least one motion sensor (eg, the motion sensor 403 ), and based on this, the user's posture can be confirmed (eg, estimated). The electronic device 101 may categorize the identified user postures and store motion data corresponding to each in a memory (eg, the memory 130 of FIG. 1 ) in association with the user posture type.

For example, the electronic device 101 checks the number of times and/or durations (eg, time at which the learned user postures are sensed) of the learned user postures, and a specified period (eg, 1 day or 1 day). Based on the number of times and/or durations detected during the week), it is possible to check the frequency of each of the learned user postures. For example, the number of learned user postures may be checked and counted when the learned user postures are maintained for a predetermined time or longer.

Referring to Table 1, the user postures and the corresponding accumulated counts (and/or daily average counts) and/or accumulated times may be mapped and stored. In Table 1, 'accumulated number' indicates the accumulated value of the number of times a user's posture was detected during a specified period (eg, one week), and 'average number of times' is the number of times a user's posture was detected on average during a day. , may represent the frequency of each user's posture. In Table 1, 'accumulated time' may represent an accumulated value of a time (eg, a duration) at which a user's posture is sensed. According to various embodiments, frequency data of user postures may be updated whenever user postures are detected, and based on the updated frequency data, at least one candidate posture to be described later may be changed.

8 is a flowchart 800 for explaining a method of determining a parameter for measuring a user's blood pressure according to various embodiments of the present disclosure.

According to various embodiments, in operation 810 , the electronic device (eg, the electronic device 101 of FIG. 1 ) may determine a parameter for measuring blood pressure based on a user posture and/or behavior session. For example, the parameter for measuring blood pressure may include a cycle, period, and/or repetition number of measuring blood pressure.

According to various embodiments, the electronic device 101 may detect a user's posture and determine a parameter for measuring blood pressure based on the sensed user's posture. According to various embodiments of the present disclosure, when a user posture corresponding to any one of at least one candidate posture for blood pressure measurement is not detected, the electronic device 101 performs a preset parameter (eg, a preset period, a preset period, and / or a preset number of repetitions) may be determined as a parameter for blood pressure measurement. According to various embodiments, when a user posture corresponding to any one of at least one candidate posture for blood pressure measurement is detected, the electronic device 101 sets a different cycle, period, and/or repetition number from a preset parameter. It can be determined as a parameter for measurement. For example, a parameter determined when a user posture corresponding to any one of at least one candidate posture for blood pressure measurement is detected (in other words, a parameter corresponding to a frequent posture) may include a period shorter than a preset period or a preset period. A period longer than the period may include a number of repetitions greater than a preset number of repetitions. According to an embodiment, when a user posture corresponding to any one of at least one candidate posture for measuring blood pressure is detected, the electronic device 101 determines a parameter corresponding to the detected user posture as a parameter for measuring blood pressure. Also, it will be described in more detail with reference to the drawings to be described later.

According to various embodiments, the electronic device 101 monitors the user's state and/or the user's posture, sets the user's behavior session, and selects a parameter for measuring blood pressure according to a time period corresponding to the behavior session. It may be determined, and it will be described in more detail with reference to the drawings to be described later.

According to various embodiments, the electronic device 101 may measure the user's blood pressure based on the determined parameter in operation 830 . For example, the electronic device 101 may measure the user's blood pressure based on a parameter corresponding to a frequent force, a parameter corresponding to a detected user posture, or a parameter corresponding to a user action session. According to an embodiment, the electronic device 101 stores the measured blood pressure value and/or data obtained therefrom in a memory (eg, the memory 130 of FIG. 1 ), and/or a display (eg, FIG. 1 ) 4 may be output (eg, displayed) through the display 401).

According to various embodiments, the electronic device 101 may measure the user's blood pressure based on different parameters according to the user's postures.

For example, the first posture 910 and the third posture 950 are candidate postures for blood pressure measurement, and the second posture 930 is a posture not learned by the electronic device 101 or blood pressure measurement. It may be a posture that is not included in the candidate posture for

According to various embodiments, when the first posture 910 is detected, the electronic device 101 measures the user's blood pressure based on the first set of parameters, and when the third posture 950 is detected, the electronic device 101 The user's blood pressure may be measured based on two sets of parameters. According to an embodiment, the first set of parameters and the parameters corresponding to the second set are parameters corresponding to frequent postures, and are preset parameters (eg, preset period, preset period, and/or preset number of repetitions). may be different from For example, the first and second sets of parameters may include a period shorter than a preset period, a period longer than the preset period, and a number of repetitions greater than the preset number of repetitions. According to an embodiment, the first set of parameters and the parameters corresponding to the second set may include a period, a period, and/or a number of repetitions of measuring blood pressure, and may include parameters that are at least partially different. For example, the first set of parameters comprises a first period, a first period and/or a first number of iterations, and the second set of parameters comprises a second period, a second period and/or a second number of iterations. and at least one of the periods, periods, or repetition times may be different. For example, if the first posture 910 corresponds to a candidate posture having a higher number (or frequency) than the third posture 950 , the first period is shorter than the second period or the first period may be longer than the second period of time, and/or the first number of repetitions may be greater than the second number of repetitions.

According to various embodiments, when the second posture 930 is sensed or the posture of the user is not detected (“X”), the electronic device 101 performs a preset parameter (eg, a preset period, a preset period). and/or a preset number of repetitions) may measure the user's blood pressure. According to an embodiment, when the second posture 930 is detected or the user's posture is not detected (“X”), the electronic device 101 may not measure the user's blood pressure.

10 is a flowchart 1000 for explaining a method of measuring a user's blood pressure by an electronic device (eg, the electronic device 101 of FIG. 1 ) according to various embodiments of the present disclosure.

According to various embodiments, the electronic device 101 may monitor the user's posture in operation 1010 . For example, the electronic device 101 uses at least one motion sensor (eg, the motion sensor 403 of FIG. 4 ) to use at least one posture element (eg, a posture of the user's body, a posture of a worn part). and/or a movement pattern of the wearing part), and based on this, the user's posture may be confirmed. According to an embodiment, the electronic device 101, irrespective of the operation of monitoring the user's posture, based on a preset parameter (eg, a preset period, a preset period, and/or a preset number of repetitions), blood pressure can also be measured.

According to various embodiments, in operation 1030 , the electronic device 101 may determine whether the monitored posture of the user corresponds to a candidate posture. For example, the electronic device 101 may check whether the checked user's posture is included in at least one candidate posture (eg, frequent posture) determined based on the number (or frequency) of the user postures detected. can

According to various embodiments, when it is determined that the monitored posture corresponds to the candidate posture, the electronic device 101 may determine whether the user is in a stable state in operation 1050 . According to various embodiments, the electronic device 101 provides motion data of the electronic device 101 provided from the motion sensor 403 and/or a biosignal provided from a PPG sensor (eg, the PPG sensor 405 of FIG. 4 ). Based on this, it is possible to check whether the user is in a stable state. For example, after the user's posture corresponding to the candidate posture is detected, the electronic device 101 maintains the magnitude of the acceleration of the electronic device 101 to be less than a certain amount (eg, a state that is less than a certain amount is longer than a threshold time) persistent) (e.g., physically stable), and/or if the user's heart rate (HR) and/or stress is found to be within a certain range (e.g., below a certain level) (e.g., mentally stable) , it can be confirmed that the user is in a stable state. According to an embodiment, the electronic device 101 may simultaneously or sequentially perform an operation of checking whether the state is physically stable and an operation of determining whether the state is mentally stable. For example, the electronic device 101 first performs an operation to determine whether a state is physically stable, and then performs an operation to determine whether a state is mentally stable or performs an operation to determine whether a state is mentally stable first. After performing, it is possible to perform an operation to check whether the state is physically stable. As another example, the electronic device 101 measures the user's heart rate to determine whether the user is in a resting state, when it is confirmed that the user is in a resting state, measures the user's stress and determines that the measured stress is within a certain range, and is physically stable. You can also check the status.

According to various embodiments, if it is determined that the monitored posture does not correspond to the candidate posture, the electronic device 101 may perform operation 1010 again.

According to various embodiments, when it is confirmed that the user is in a stable state, the electronic device 101 may measure the user's blood pressure in operation 1070 .

According to various embodiments, reference numeral 1301 may indicate information about a user's blood pressure value (in other words, blood pressure value [mmHg]) (hereinafter, blood pressure value information). For example, as shown in FIG. 13A , “118” may indicate the highest value of the user's blood pressure value, and “76” may indicate the lowest value of the user's blood pressure value.

According to various embodiments, the blood pressure value information 1301 may indicate the user's current blood pressure value. For example, the electronic device 101 may include various user interfaces (eg, a touch screen, a physical key, a microphone, and/or a motion sensor) (eg, the display 401 of FIG. 4 , the key input device 202 of FIG. 2A ). , 290), through the input module 150 of FIG. 1 and/or the motion sensor 403 of FIG. 4 ), an input (eg, a touch input, a key input, a voice input, and/or a motion) for initiating blood pressure measurement of the user. input) can be received.

According to various embodiments, the blood pressure value information 1301 may indicate a current blood pressure value of the user identified based on a blood pressure value measured a plurality of times. For example, when performing an operation of measuring the user's blood pressure, the electronic device 101 may sequentially (or repeatedly) measure the user's blood pressure a plurality of times. An average value of the blood pressure values measured several times may be calculated, and the calculated average value may be displayed as the current blood pressure value of the user.

According to various embodiments, the blood pressure value information 1301 may indicate a blood pressure value measured for a user's preset period (eg, during one day). For example, the electronic device 101 performs an operation (eg, start operation) of measuring the user's blood pressure based on reception of an input for starting measurement of the user's blood pressure, detection of a frequent posture, and/or a preset period. It may be performed multiple times to obtain a plurality of blood pressure values, and based on the obtained plurality of blood pressure values, a blood pressure value measured for a user's preset period (eg, during one day) may be determined.
