These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0039] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate.

[0044] FIG. 2A is a diagram illustrating a wearable electronic device worn by a user at rest according to one embodiment.

[0045] According to one embodiment, the wearable electronic device (201) may be implemented as various types of electronic devices that can be worn by a user, such as a smart watch, a smart band, a smart ring, wireless earphones, or smart glasses. According to one embodiment, the wearable electronic device (201) may be a device that can be worn on the user's wrist or a device that can be worn on another part of the human body (e.g., an upper arm, a head, a thigh, etc.). According to one embodiment, the wearable electronic device (201) may also be implemented as various types of electronic devices (e.g., a smartphone) that can perform a communication function rather than a type that can be worn by a user. According to one embodiment, the wearable electronic device (201) may be implemented in a manner identical to or similar to the electronic device (101) of FIG. 1.

[0046] According to one embodiment, the wearable electronic device (201) can measure biometric information of a user. For example, the wearable electronic device (201) can obtain a biometric signal (e.g., a PPG signal) for measuring biometric information of a user (203) by outputting light from a sensor (e.g., a PPG sensor) included in the wearable electronic device (201). For example, the biometric signal may refer to a signal corresponding to light that is reflected by the skin of the user (203) from a light emitting unit of the sensor included in the electronic device (201) and at least partially received or obtained by a light receiving unit of the sensor. For example, the biometric signal may include a photoplethysmography (PPG) signal or a PPG measurement signal. The wearable electronic device (201) can analyze the PPG signal to measure various biometric information of the user (e.g., heart rate, pulse, saturation of peripheral oxygen (SpO2), or blood pressure).

[0047] According to one embodiment, the wearable electronic device (201) can determine whether the user is in a resting state. For example, if the user is determined to be in a resting state, the user may exhibit little or no movement. According to one embodiment, the wearable electronic device (201) can determine the user's movement using a sensor (e.g., a motion sensor or an acceleration sensor) included in the wearable electronic device (201) and determine whether the user is in a resting state based on the determined movement. For example, if the user is determined to be in a resting state, the wearable electronic device (201) may not continuously measure the user's biometric information. For example, the wearable electronic device (201) may measure the user's biometric information at designated intervals. Through this, the wearable electronic device (201) can reduce power consumption due to the measurement of biometric information.

[0048] However, if a wearable electronic device is configured to measure a user's biometric information at specified intervals, existing wearable electronic devices may not be able to measure the user's biometric information outside of those times. Consequently, existing wearable electronic devices may not be able to immediately notify the user if an abnormality in the user's heart rate occurs.

[0049] According to one embodiment of the present invention, a wearable electronic device (201) may continuously measure a user's heart rate for a specific period of time when an abnormal heart rate is detected in a state or mode of the wearable electronic device set to measure the user's heart rate at specified time intervals. Through this, the wearable electronic device (201) according to one embodiment may effectively provide a notification to the user indicating an abnormal heart rate.

[0050] FIG. 2b is a schematic block diagram of a configuration of a wearable electronic device according to one embodiment.

[0051] According to one embodiment, a wearable electronic device (201) (e.g., the electronic device (101) of FIG. 1 or the wearable electronic device (201) of FIG. 2A) may include a processor (220), a memory (230), a display (260), a first sensor (270), a second sensor (280), and a communication circuit (290).

[0052] According to one embodiment, the processor (220) can control the overall operation of the wearable electronic device (201). For example, the processor (220) can be implemented in the same or similar manner as the processor (120) of FIG. 1.

[0053] According to one embodiment, the processor (220) (e.g., the processor (120) of FIG. 1) may obtain a biosignal for measuring the user's bioinformation through the first sensor (270).

[0054] According to one embodiment, the first sensor (270) may include a photoplethysmography (PPG) sensor. According to one embodiment, the processor (220) may output a first light to a body part (e.g., skin) of the user using the first sensor (270). According to one embodiment, the processor (220) may obtain a signal (hereinafter, referred to as a biosignal) corresponding to light reflected by the body part of the user using the first sensor (270). For example, the processor (220) may obtain a PPG signal using the first sensor (270). According to one embodiment, the processor (220) may obtain or measure bioinformation including the user's heart rate, oxygen saturation, stress, arrhythmia, and / or blood pressure based on the obtained biosignal (e.g., PPG signal).

[0055] Depending on the implementation, the first sensor (270) may include a plurality of electrodes. The plurality of electrodes may be used to detect or sense a voltage corresponding to electrical resistance or a voltage corresponding to electrical conductivity by directly contacting the user's skin. According to one embodiment, the processor (220) may obtain an electrodermal activity (EDA) including a galvanic skin reflex (GSR), a bioelectrical impedance analysis (BIA) signal, and / or an electrocardiogram (ECG) signal using the first sensor (270). According to one embodiment, the processor (220) may measure bio-information including an electrocardiogram and / or body fat based on the bio-signal. However, the present invention is not limited thereto, and the first sensor (270) may include various types of sensors that may obtain or measure the user's bio-information.

[0056] According to one embodiment, the processor (220) can acquire biosignals at preset time intervals or continuously for a specific period of time using the first sensor (270).

[0057] According to one embodiment, the processor (220) may measure the user's first heart rate using the first sensor (270) for a first period of time (e.g., 30 seconds) in a first state of the wearable electronic device (201) (e.g., a state in which the wearable electronic device (201) is operating in a rest mode) that is set to measure the user's heart rate at a specified time interval (e.g., every 10 minutes). For example, the processor (220) may measure the user's heart rate every 10 minutes in the rest mode. The first heart rate may represent the user's heart rate measured in the first state (e.g., a state in which the wearable electronic device (201) is operating in a rest mode).

[0058] According to one embodiment, the processor (220) may determine whether the first heart rate is outside a designated range. For example, the designated range may be set to a range indicating a normal heart rate. For example, the designated range may indicate a heart rate range that is lower than a first reference value indicating a high heart rate and higher than a second reference value (e.g., a value lower than the first reference value) indicating a low heart rate. For example, the first reference value and the second reference value may be values ​​preset by the user or by the processor (220). Additionally, the first reference value and the second reference value may be determined based on the user's personal information (e.g., height, weight, gender, and / or body fat).

[0059] According to one embodiment, the processor (220) may measure the second heart rate of the user using the first sensor (270) for a second period of time after the first period of time based on determining that the first heart rate is outside a specified range. In this case, the processor (220) may continuously measure the user's heart rate for a specified second period of time (e.g., 10 minutes). For example, the second heart rate may represent the user's heart rate continuously measured during the second period of time. Additionally, the second heart rate may include a plurality of heart rate values ​​continuously measured during the second period of time.

[0060] In one embodiment, the processor (220) may determine whether the percentage of heart rates measured during the second time period that fall outside a specified range exceeds a specified percentage. For example, the specified percentage may represent a percentage (e.g., 80%) for determining an abnormality in the user's heart rate. The specified percentage may be set by the user or automatically by the processor (220).

[0061] According to one embodiment, if it is determined that the ratio of the second heart rate measured during the second time period that falls outside a specified range exceeds the specified ratio, the processor (220) may output a notification indicating an abnormality in the user's heart rate. For example, the processor (220) may display a notification indicating an abnormality in the heart rate through the display (260). The processor (220) may display information about the measured heart rate through the display (260). Depending on the implementation, the processor (220) may output a notification indicating an abnormality in the heart rate through a speaker (not shown).

[0062] According to one embodiment, the processor (220) may store a history of notifications indicating abnormalities in heart rate in the memory (230). In addition, the processor (220) may store information about measured heart rate in the memory (230).

[0063] According to one embodiment, the processor (220) may transmit information about the measured heart rate to an external electronic device (e.g., a terminal in communication with the wearable electronic device (201)) through the communication circuit (290). In addition, the processor (220) may transmit a control signal to the external electronic device through the communication circuit (290) so as to cause the external electronic device to output a notification indicating an abnormality in the heart rate.

[0064] According to one embodiment, the second sensor (280) can obtain a sensing value corresponding to the movement of a user wearing the wearable electronic device (201). The second sensor (280) can be implemented in the same or similar manner as the sensor module (176) of FIG. 1. For example, the second sensor (280) can include at least one of an acceleration sensor, an inertial sensor, a motion sensor, an IR (infrared ray) sensor, a temperature (body temperature) sensor, a gyro sensor, a gravity sensor (or a geomagnetic sensor), a proximity sensor, an illuminance sensor, a TOF sensor, or a barometer sensor. However, the present invention is not limited thereto, and the second sensor (272) can include various types of sensors that can detect the movement of the user.

[0065] According to one embodiment, the processor (220) may use the second sensor (280) to determine whether the user is resting. In addition, the processor (220) may also use the second sensor (280) to determine whether the user is exercising. For example, the processor (220) may compare a sensing value indicating a movement of a user wearing the wearable electronic device (201) with specified values, and determine whether the user is resting or exercising based on the comparison result. For example, if the sensing value indicating the movement of the user is greater than a first specified value, the processor (200) may determine that the user is exercising. Alternatively, the processor (220) may determine that the user is resting if the sensing value indicating the movement of the user is less than a second specified value (e.g., a value less than the first specified value).

[0066] According to one embodiment, the processor (220) may display the user's biometric information (e.g., heart rate) measured using the first sensor (270) on the display (260) (e.g., the display module (160) of FIG. 1). In addition, the processor (220) may display a notification indicating an abnormal heart rate on the display (260) (e.g., the display module (160) of FIG. 1). For example, the notification may include at least one of a heart rate value corresponding to the abnormal heart rate, information explaining the abnormal heart rate, and information regarding emergency measures.

[0067] According to one embodiment, the processor (220) may transmit the user's biometric information measured using the first sensor (270) to an external electronic device (not shown) via a communication circuit (290) (e.g., the communication module (190) of FIG. 1).

[0068] FIG. 3 is a schematic diagram illustrating a structure of a first sensor according to one embodiment.

[0069] Referring to FIG. 3, according to one embodiment, a first sensor (e.g., the first sensor (270) of FIG. 2b) may be placed on the rear side of the wearable electronic device (201) (e.g., the part that comes into contact with the user's wrist). For example, the first sensor (270) may be implemented as a PPG sensor.

[0070] According to one embodiment, the first sensor (270) may include a plurality of light-emitting elements (271, 272) and a plurality of light-receiving elements (276, 277, 278). For example, the plurality of light-emitting elements (271, 272) may include light emitting diodes (LEDs). For example, the plurality of light-receiving elements (276, 277, 278) may include at least one of an avalanche photodiode (APD), a single photon avalanche diode (SPAD), a photodiode, a photomultiplier tube (PMT), a charge-coupled device (CCD), a CMOS array, and a spectrometer. Although, for convenience of explanation, the number, shape, size, type, and position of light-emitting elements and light-receiving elements are illustrated in FIG. 3, the number, shape, size, type, and position of light-emitting elements and light-receiving elements are not limited thereto and may be implemented in various forms.

[0071] According to one embodiment, each of the plurality of light-emitting elements (271, 272) can output light to a body part of a user wearing the wearable electronic device (201) (e.g., the user's skin in contact with the wearable electronic device (201). For example, the light can include at least one of red light, green light, blue light, or infrared light. For example, the electronic device (201) can use light in a green wavelength band to measure a heart rate. Since light in a green wavelength band relatively shallowly penetrates the user's skin, the electronic device (201) can obtain a biosignal with less noise. According to one embodiment, the electronic device (201) can use light in a red wavelength band to measure a heart rate. Since light in the red wavelength band penetrates relatively deeply into the user's skin, the electronic device (201) can measure a more accurate heart rate. According to one embodiment, the electronic device (201) can measure a heart rate and oxygen saturation (SpO2) using light in the infrared ray wavelength band. The electronic device (201) can measure a relatively more diverse range of bio-information using light in the infrared ray wavelength band than when light in other wavelength bands is used. According to one embodiment, the electronic device (201) can measure a user's skin tone using light in the infrared ray wavelength band, red wavelength band, and green wavelength band. According to one embodiment, the electronic device (201) can also measure a user's blood sugar level using light in the blue wavelength band. The electronic device (201) can measure bio-information using light in an appropriate wavelength band.

[0072] According to one embodiment, the plurality of light-receiving elements (276, 277, 278) can receive at least a portion of the light output from the plurality of light-emitting elements (271, 272) that is reflected or transmitted by the user's body tissue (e.g., skin, skin tissue, fat layer, veins, arteries, and / or capillaries, etc.).

[0073] In one embodiment, although not shown, the wearable electronic device (201) may include an analog-to-digital converter (ADC). In one embodiment, the wearable electronic device (201) may convert signals output from a plurality of light-receiving elements (276, 277, 278) from analog signals to digital signals through the ADC. In one embodiment, the ADC may be separately provided between the light-receiving unit (320) and the processor (220).

[0074] According to one embodiment, the processor (220) may acquire a digital signal converted by the ADC as a user's biosignal. The processor (220) may analyze the biosignal to measure or acquire the user's bioinformation (e.g., the user's heart rate).

[0075] According to one embodiment, the wearable electronic device (201) may further include a plurality of electrodes (251, 252, and 253). For example, the first electrode (251) and the second electrode (252) may be positioned on the rear surface of the wearable electronic device (201) (e.g., a portion that comes into contact with the user's wrist). The third electrode (253) may be positioned on the side surface of the wearable electronic device (201) (e.g., above a button located on the side surface). A wearable electronic device (201) can obtain a bio-signal (e.g., an electrodermal activity (EDA) including a galvanic skin reflex (GSR), a bioelectrical impedance analysis (BIA) signal, and / or an electrocardiogram (ECG) signal) for measuring a user's bio-information (e.g., an electrocardiogram, a skin conductance, or a body composition) using a plurality of electrodes (251, 252, and 253). A processor (220) can analyze the bio-signal to measure or obtain the user's bio-information (e.g., an electrocardiogram, a skin conductance, or a body composition).

[0076] The operations of the wearable electronic device (201) described below may be performed or controlled by the processor (220). However, for convenience of explanation, the operations performed or controlled by the processor (220) will be described as being performed by the wearable electronic device (201).

[0077] Meanwhile, the operations of the wearable electronic device (201) will be described below with a focus on the operation of measuring the user's heart rate. However, the technical concept of the present invention can be applied not only to the operation of measuring the user's heart rate, but also to the operation of measuring various biometric information of the user.

[0078] FIG. 4 is a flowchart illustrating the operation of a wearable electronic device according to one embodiment.

[0079] Referring to FIG. 4, according to one embodiment, in operation 401, a wearable electronic device (e.g., the wearable electronic device (201) of FIG. 2A) may measure a first heart rate of the user using a first sensor (e.g., the first sensor (270) of FIG. 2B) for a first period of time (e.g., 30 seconds) in a first state (e.g., a state operating in a resting mode) set to measure a heart rate of the user at a specified time interval. For example, when the specified time arrives, the wearable electronic device (201) may measure the first heart rate of the user using the first sensor (270) for the first period of time.

[0080] According to one embodiment, in operation 403, the wearable electronic device (201) may measure the second heart rate of the user using the first sensor (270) for a second period of time (e.g., 10 minutes) after the first period of time based on determining that the first heart rate is outside the designated range. For example, the wearable electronic device (201) may continuously measure the second heart rate of the user for a longer period of time if it determines that the first heart rate is outside the designated range. For example, the designated range may represent a range of a normal heart rate.

[0081] According to one embodiment, in operation 405, if it is determined that the ratio of heart rates out of a specified range among the second heart rates measured during the second time period exceeds a specified ratio (e.g., 80%), the wearable electronic device (201) may output a notification indicating an abnormality in the user's heart rate. For example, the specified ratio may be set as a ratio for determining an abnormality in the heart rate. For example, the wearable electronic device (201) may output a notification indicating an abnormality in the user's heart rate through auditory, visual, or tactile (e.g., vibration) means.

[0082] According to one embodiment, in operation 407, the wearable electronic device (201) may store information about the measured heart rate and notification details in a memory (e.g., memory (230) of FIG. 2B). In addition, the wearable electronic device (201) may transmit information about the measured heart rate and notification details to an external electronic device that is in communication with the wearable electronic device (e.g., a connection based on Bluetooth communication).

[0083] According to the method described above, the wearable electronic device (201) can continuously measure the user's heart rate for a specific period of time when an abnormal heart rate is detected in a state or mode of the wearable electronic device set to measure the user's heart rate at a specified time interval. Thus, the wearable electronic device (201) according to one embodiment can effectively provide the user with a notification indicating an abnormal heart rate.

[0084] FIG. 5 is a flowchart illustrating a method by which a wearable electronic device according to one embodiment initiates measurement of a second heart rate.

[0085] Referring to FIG. 5, according to one embodiment, a wearable electronic device (e.g., wearable electronic device (201) of FIG. 2A) may determine whether a user is resting in a first state set to measure the user's heart rate at specified intervals. According to one embodiment, in operation 501, the wearable electronic device (e.g., wearable electronic device (201) of FIG. 2A) may determine the user's movement using a second sensor (e.g., second sensor (280) of FIG. 2B).

[0086] According to one embodiment, in operation 503, the wearable electronic device (201) may determine whether the user is resting based on the identified movement of the user. For example, if the sensing value indicating the movement of the user sensed by the second sensor (280) is determined to be less than a specified value, the wearable electronic device (201) may determine that the user is resting. Alternatively, the wearable electronic device (201) may determine that the user is resting if it is determined that the wearable electronic device (201) is operating in a rest mode.

[0087] In one embodiment, if it is determined that the user is not resting (NO of operation 503), the wearable electronic device (201) may re-determine whether the user is resting.

[0088] In one embodiment, if it is determined that the user is resting (e.g., in operation 503), in operation 505, the wearable electronic device (201) may determine whether a designated time (e.g., 0 minutes, 10 minutes, 20 minutes, 30 minutes, 40 minutes, and 50 minutes of every hour) set to measure the user's heart rate has arrived. The wearable electronic device (201) may determine whether a designated time set to measure the user's heart rate has arrived using a preset timer.

[0089] In one embodiment, if it is determined that the designated time has not arrived (NO of operation 505), the wearable electronic device (201) may re-check whether the user is resting.

[0090] According to one embodiment, when it is determined that a designated time has arrived (e.g., operation 505), in operation 507, the wearable electronic device (201) may acquire a first biosignal using the first sensor (270) for a designated first time period (e.g., 30 seconds) to measure a first heart rate. For example, the first biosignal may include a PPG signal acquired during the first time period.

[0091] According to an embodiment, in operation 509, the wearable electronic device (201) may check the signal-to-noise ratio (SNR) of the first biosignal. In addition, the wearable electronic device (201) may check whether the SNR of the first biosignal is greater than a specified value. For example, if the SNR of the first biosignal is determined to be greater than the specified value, the wearable electronic device (201) may determine that the first biosignal is a signal of sufficient quality to measure the user's heart rate. For example, the specified value may represent a reference value for determining whether the first biosignal is a signal of sufficient quality to measure the user's heart rate. For example, when the heart rate is measured as 60 bpm, the wearable electronic device (201) may determine an area corresponding to 60 bpm+5 bpm to 60 bpm-5 bpm as a signal area, and the remaining area as a noise area. For example, the value of signal area / (signal area + noise area) of the first biosignal may be SNR, and the specified value may be set to 0.2.

[0092] Depending on the implementation, the wearable electronic device (201) may determine that the first biosignal is a signal of sufficient quality to measure the user's heart rate if it is determined that the peak of the waveform of the first biosignal is identical to or similar to a peak of a specified shape.

[0093] According to one embodiment, if the SNR of the first biosignal is determined to be greater than the specified value (NO of operation 509), the wearable electronic device (201) may re-determine whether the user is resting.

[0094] According to one embodiment, if it is determined that the SNR of the first biosignal is not greater than a specified value (example of operation 509), in operation 511, the wearable electronic device (201) may determine whether the measured first heart rate is outside a specified range. For example, the specified range may be a range indicating a normal heart rate.

[0095] In one embodiment, if it is determined that the first heart rate is not outside the specified range (NO of operation 511), the wearable electronic device (201) may re-determine whether the user is resting.

[0096] According to one embodiment, if the first heart rate is determined to be outside the specified range (e.g., in operation 511), the wearable electronic device (201) may initiate an operation of measuring a second heart rate in operation 513. For example, if the wearable electronic device (201) is determined to be outside the specified range, the wearable electronic device (201) may initiate an operation of continuously checking or examining the user's heart rate for a longer period of time. The operation of the wearable electronic device (201) measuring the second heart rate will be described in more detail in FIG. 6 below.

[0097] FIG. 6 is a flowchart illustrating a method for a wearable electronic device according to one embodiment to output a notification based on a second heart rate.

[0098] Referring to FIG. 6, according to one embodiment, at operation 601, a wearable electronic device (e.g., the wearable electronic device (201) of FIG. 2A) may initiate an operation of continuously measuring a second heart rate of a user for a second period of time (e.g., 10 minutes) using a first sensor (e.g., the first sensor (270) of FIG. 2B).

[0099] According to one embodiment, in operation 603, the wearable electronic device (201) may determine whether the measurement of the second heart rate is for checking a low heart rate. For example, if the wearable electronic device (201) determines that the first heart rate is lower than a second reference value (e.g., 50 bpm) indicating a low heart rate, the wearable electronic device (201) may perform an operation to check or re-check a low heart rate. Alternatively, if the wearable electronic device (201) determines that the first heart rate is higher than a first reference value (e.g., 120 bpm) indicating a high heart rate, the wearable electronic device (201) may perform an operation to check or re-check a high heart rate.

[0100] According to one embodiment, if it is determined that the measurement of the second heart rate is not for checking a low heart rate (NO in operation 603), in operation 605, the wearable electronic device (201) may use the second sensor (e.g., the second sensor (280) of FIG. 2B) to check the user's movement. For example, if it is determined that the measurement of the second heart rate is not for checking a low heart rate, the wearable electronic device (201) may determine that the measurement of the second heart rate is for checking a high heart rate. Since the user's heart rate may temporarily increase when the user moves a lot, the wearable electronic device (201) may check the degree of the user's movement.

[0101] According to one embodiment, in operation 607, the wearable electronic device (201) may determine whether a sensing value indicating the user's movement is greater than a specified value. In this case, the specified value may include a value indicating a state in which the user is exercising. For example, the wearable electronic device (201) may determine whether a sensing value indicating the user's movement is greater than a specified value during a certain period of time (e.g., a time interval from a time before a certain time to a time after a certain time based on the current time or a time interval from the current time to a certain time).

[0102] According to one embodiment, if the sensing value indicating the user's movement is determined to be greater than a specified value (e.g., in operation 607), in operation 617, the wearable electronic device (201) may stop the operation of measuring the second heart rate. In this case, the wearable electronic device (201) may determine that there is no need to continue checking the second heart rate. In addition, the wearable electronic device (201) may not output a notification indicating an abnormality in the user's heart rate.

[0103] According to one embodiment, if it is determined that the sensing value indicating the user's movement is not greater than a specified value (NO in operation 607), in operation 609, the wearable electronic device (201) may check the wearing state of the wearable electronic device (201). According to one embodiment, if it is determined that the measurement of the second heart rate is for checking a low heart rate (YES in operation 603), in operation 609, the wearable electronic device (201) may check the wearing state of the wearable electronic device (201). For example, the wearable electronic device (201) may use the first sensor (270) to check whether the wearable electronic device (201) is worn by the user.

[0104] According to one embodiment, in operation 611, the wearable electronic device (201) may determine whether the wearing state of the wearable electronic device (201) satisfies a specified condition. For example, the specified condition may be a condition indicating whether the wearing state is maintained sufficiently to measure the user's heart rate for a second period of time. For example, the wearable electronic device (201) may determine whether the wearable electronic device (201) is maintained in a state worn by the user for a second period of time to measure the second heart rate.

[0105] According to one embodiment, if it is determined that the wearing state of the wearable electronic device (201) does not satisfy the specified condition (NO in operation 611), in operation 617, the wearable electronic device (201) may stop the operation of measuring the second heart rate. In this case, the wearable electronic device (201) may determine that there is no need to continue checking the second heart rate. In addition, the wearable electronic device (201) may not output a notification indicating an abnormality in the user's heart rate.

[0106] According to one embodiment, if it is determined that the wearing state of the wearable electronic device (201) satisfies a specified condition (example of operation 611), in operation 613, the wearable electronic device (201) can determine whether a ratio of heart rates out of a specified range among second heart rates measured during a second time period exceeds a specified ratio.

[0107] According to one embodiment, if it is determined that the ratio of heart rates out of the specified range among the second heart rates measured during the second time period exceeds the specified ratio (example of operation 613), in operation 615, the wearable electronic device (201) may output a notification indicating an abnormality in the user's heart rate. After outputting the notification, the wearable electronic device (201) may continue to monitor the user's heart rate. For example, after outputting the notification, the wearable electronic device (201) may sequentially perform operations starting from operation 601 again. That is, after outputting the notification, the wearable electronic device (201) may continuously measure the user's heart rate for a specified time period (e.g., the second time period).

[0108] According to one embodiment, if it is determined that the ratio of heart rates out of the specified range among the second heart rates measured during the second time period does not exceed the specified ratio (NO in operation 613), in operation 617, the wearable electronic device (201) may stop the operation of measuring the second heart rate. In this case, the wearable electronic device (201) may determine that there is no need to continue checking the second heart rate. In addition, the wearable electronic device (201) may not output a notification indicating an abnormality in the user's heart rate. For example, after the wearable electronic device (201) determines not to output a notification, the wearable electronic device (201) may sequentially perform operations starting from operation 501 of FIG. 5 again. That is, after the wearable electronic device (201) determines not to output a notification, the wearable electronic device (201) may measure the user's heart rate again at specified intervals.

[0109] FIG. 7 is a flowchart illustrating an operation of a wearable electronic device outputting a notification according to one embodiment.

[0110] Referring to FIG. 7, in one embodiment, at operation 701, in one embodiment, at operation 601, a wearable electronic device (e.g., the wearable electronic device (201) of FIG. 2A) may measure a second heart rate of a user for a second period of time (e.g., 10 minutes) using a first sensor (e.g., the first sensor (270) of FIG. 2B).

[0111] According to one embodiment, in operation 703, the wearable electronic device (201) may determine whether the measurement of the second heart rate is for checking a low heart rate. For example, if the wearable electronic device (201) determines that the first heart rate is lower than a second reference value (e.g., 50 bpm) indicating a low heart rate, the wearable electronic device (201) may perform an operation to check or re-check a low heart rate. Alternatively, if the wearable electronic device (201) determines that the first heart rate is higher than a first reference value (e.g., 120 bpm) indicating a high heart rate, the wearable electronic device (201) may perform an operation to check or re-check a high heart rate.

[0112] According to one embodiment, if it is determined that the measurement of the second heart rate is not for checking a low heart rate (i.e., for checking a high heart rate) (NO in operation 703), in operation 705, the wearable electronic device (201) may provide information indicating a high heart rate of the user through a notification if the ratio of the heart rate higher than the first reference value among the second heart rates exceeds a specified ratio.

[0113] According to one embodiment, if the measurement of the second heart rate is determined to be for checking a low heart rate (example of operation 703), in operation 707, the wearable electronic device (201) may provide information indicating a low heart rate of the user through a notification if the ratio of the heart rate lower than the second reference value among the second heart rates exceeds a specified ratio.

[0114] FIG. 8 is a flowchart illustrating an operation of a wearable electronic device according to one embodiment of the present invention to stop measuring a second heart rate when an execution command for another function is confirmed.

[0115] Referring to FIG. 8, according to one embodiment, in operation 801, a wearable electronic device (e.g., the wearable electronic device (201) of FIG. 2A) may measure a second heart rate for a second time using a first sensor (e.g., the first sensor (270) of FIG. 2B).

[0116] According to one embodiment, in operation 803, the wearable electronic device (201) may determine whether execution of another function of the wearable electronic device (201) is commanded while measuring the second heart rate. For example, the other function may include a function related to an exercise mode of the wearable electronic device (201). Alternatively, the other function may include a function of measuring heart rate and other biometric information using the first sensor (270) of the wearable electronic device (201).

[0117] In one embodiment, if it is determined that the execution of another function is not commanded (NO in operation 803), in operation 805, the wearable electronic device (201) may continue to measure the second heart rate for a second time period. In another embodiment, if it is determined that a command to execute a function of the wearable electronic device unrelated to measuring the second heart rate is commanded, the wearable electronic device (201) may continue to measure the second heart rate for a second time period.

[0118] According to one embodiment, if it is determined that execution of another function is commanded (example of operation 803), in operation 807, the wearable electronic device (201) may stop measuring the second heart rate. For example, the wearable electronic device (201) may output a notification (e.g., a notification via visual means, auditory means, and / or tactile means) indicating that measurement of the second heart rate has stopped. For example, when a user starts exercising, the wearable electronic device (201) may not be able to accurately measure the user's heart rate because the exercise increases the user's heart rate. In addition, when measuring other biometric information of the user using the first sensor (270), the wearable electronic device (201) may not be able to accurately measure the user's heart rate. Accordingly, when another function of the wearable electronic device (201) is executed, the wearable electronic device (201) may determine that there is no need to continue checking the second heart rate.

[0119] According to another embodiment, the wearable electronic device (201) may not start measuring the second heart rate if it is determined that another function of the wearable electronic device (201) is already running at the step of starting measuring the second heart rate.

[0120] In another embodiment, the wearable electronic device (201) may continue to measure the second heart rate for a second period of time while a function of the wearable electronic device unrelated to measuring the second heart rate is running.

[0121] According to the method described above, the wearable electronic device (201) can continuously measure the user's heart rate for a specific period of time when an abnormal heart rate is detected in a state or mode of the wearable electronic device set to measure the user's heart rate at a specified time interval. Thus, the wearable electronic device (201) according to one embodiment can effectively provide the user with a notification indicating an abnormal heart rate.

[0122] FIG. 9 is a diagram illustrating a notification provided by a wearable electronic device according to one embodiment.

[0123] Referring to FIG. 9, according to an embodiment, a wearable electronic device (e.g., the wearable electronic device (201) of FIG. 2A) may display a notification (910) indicating an abnormality in the user's heart rate on a display (e.g., the display (260) of FIG. 2B) based on a measurement result of a second heart rate. For example, the notification (910) may include information about a heart rate value (e.g., 125 bmp) corresponding to the heart rate abnormality and / or information about heart rate values ​​measured during a second time period. For example, the wearable electronic device (201) may display the heart rate values ​​measured during the second time period as graphical information using a graph and / or dots. Depending on the implementation, the notification (910) may further include a guide (e.g., health-related information) that is helpful for the heart rate abnormality.

[0124] FIG. 10 is a diagram showing information about a user's heart rate provided by a wearable electronic device according to one embodiment.
