[0022] FIG. 14A illustrates a perspective view of an exemplary electronic device according to one embodiment.

[0023] FIG. 14b is an example of a partial cross-sectional view of an electronic device according to one embodiment.

[0024] Figure 1 illustrates an example of a wireless environment including a wearable device and an external electronic device.

[0025] Referring to FIG. 1, a wearable device (101) may include a housing defining an exterior appearance of the wearable device (101). The housing of the wearable device (101) may include a first side facing a part of the user's body (e.g., a finger) and a second side opposite the first side. For example, the housing of the wearable device (101) may have a ring shape. An example of the structure of a wearable device (101) having a ring shape is described with reference to FIGS. 14A and 14B.

[0026] For example, the size of the wearable device (101) may be relatively small compared to the size of the external electronic device (102). For example, the space that can be allocated for a rechargeable battery within the wearable device (101) may be relatively small. For example, due to such space constraints, the rechargeable battery included in the wearable device (101) may have a relatively small capacity. For example, because the rechargeable battery of the wearable device (101) has a relatively small capacity, a method for reducing the power consumed within the wearable device (101) may be required.

[0027] For example, the wearable device (101) may include a first sensor. For example, the first sensor may be used to detect whether the wearable device (101) is being worn by a user of the wearable device (101).

[0028] For example, the wearable device (101) may include a second sensor. For example, the second sensor may be used to obtain biometric information of a user of the wearable device (101).

[0029] For example, the wearable device (101) may acquire biometric information of a user of the wearable device (101) through the second sensor while the second sensor is activated. For example, the wearable device (101) acquiring biometric information of a user of the wearable device (101) through the second sensor may cause power consumption within the wearable device (101). As a non-limiting example, maintaining the second sensor activated while the user of the wearable device (101) is in a situation that does not require acquisition of biometric information may cause unnecessary power consumption within the wearable device (101). For example, a method may be required to identify or detect such a situation to reduce power consumption within the wearable device (101). As a non-limiting example, the method may be executed within the wearable device (101) to deactivate the second sensor.

[0030] For example, the wearable device (101) may include a communication circuit. For example, the communication circuit may be used to transmit (103) information (e.g., acquired through a first sensor) regarding whether the wearable device (101) is worn by a user of the wearable device (101) to an external electronic device (102). For example, the communication circuit may be used to transmit (103) biometric information (e.g., acquired through a second sensor) of a user of the wearable device (101) to the external electronic device (102).

[0031] For example, the external electronic device (102) may include a communication circuit. For example, the communication circuit of the external electronic device (102) may be used to receive (103) information from the wearable device (101) about whether the wearable device (101) is worn by a user of the wearable device (101). For example, the communication circuit of the external electronic device (102) may be used to receive (103) biometric information of a user of the wearable device (101) from the wearable device (101).

[0032] For example, the wearable device (101) may transmit (103) biometric information of a user of the wearable device (101) to an external electronic device via the communication circuit while the communication circuit is activated. For example, transmitting (103) biometric information of a user of the wearable device (101) to an external electronic device via the communication circuit may cause power consumption within the wearable device (101). As a non-limiting example, maintaining the communication circuit activated while the user of the wearable device (101) is in a situation where the user does not require transmitting (103) biometric information to an external electronic device (102) may cause unnecessary power consumption within the wearable device (101). For example, a method may be required to identify or detect such a situation to reduce power consumption within the wearable device (101). As a non-limiting example, the method may be executed within a wearable device (101) to disable communication circuitry.

[0033] As a non-limiting example, a wearable device (101) may be described as a device that (primarily) transmits information to an external electronic device (102) (103) and receives information from the external electronic device (102) (104). For example, the frequency of transmissions (103) from the wearable device (101) to the external electronic device (102) may be greater than the frequency of transmissions (104) from the external electronic device (102) to the wearable device (101). For example, the wearable device (101) may operate relatively less frequently in response to receiving data or information (104) from the external electronic device (102).

[0034] For example, the wearable device (101) may not include a display. For example, the wearable device (101) may include a relatively small display. As a non-limiting example, the display of the wearable device (101) may be a hardware component of the wearable device (101) for performing auxiliary functions of the wearable device (101). For example, the wearable device (101) may be described as a device whose main functions include collecting information about the user's body condition (e.g., biometric information) and transmitting (103) a signal to an external electronic device (102) to provide a service related to the collected information. As a non-limiting example, the frequency of providing visualized information using data received from the external electronic device (102) using the wearable device (101) may be relatively low. For example, the wearable device (101) may not include a speaker. As a non-limiting example, the frequency with which a wearable device provides audio via audio data received from an external electronic device (102) may be relatively low.

[0035] For example, the communication circuit of the wearable device (101) may be disabled to cause relatively low power consumption within the wearable device (101). For example, even if the communication circuit is disabled, the wearable device (101) may not have an error in receiving information or signals (104) from an external electronic device (102).

[0036] For example, the communication circuit of the wearable device (101) can be used to transmit (103) information or signals to an external electronic device (102).

[0037] For example, the frequency with which the wearable device (101) receives input from a user of the wearable device (101) may be relatively low. For example, the wearable device (101) may not include a configuration capable of identifying input from a user of the wearable device (101). For example, the frequency with which the wearable device (101) transmits (103) a signal according to an input from a user to an external electronic device (102) may be relatively low.

[0038] For example, the wearable device (101) can transmit (103) biometric information of a user of the wearable device (101) to an external electronic device (102) via a communication circuit. For example, the biometric information of the user of the wearable device (101) can include information indicating an emergency situation of the user of the wearable device (101).

[0039] For example, the wearable device (101) can obtain information indicating an emergency situation of a user of the wearable device (101) through a second sensor. For example, the second sensor can be composed of at least one sensor. As a non-limiting example, it can include at least one of an acceleration sensor, a gyro sensor, a photoplethysmography (PPG) sensor, a barometric pressure sensor, and an electrode sensor.

[0040] For example, the biometric information of the user of the wearable device (101) may include information indicating an emergency situation of the user of the wearable device (101). For example, the wearable device (101) may identify that the user of the wearable device (101) is in an emergency situation. For example, the wearable device (101) may obtain acceleration information through an acceleration sensor to identify whether the user of the wearable device (101) has fallen. For example, the wearable device (101) may identify an air pressure change rate and an air pressure change through an air pressure sensor in a time interval that includes a point in time when an acceleration greater than a predefined reference size is detected. For example, the wearable device (101) may identify that a fall has occurred in the user of the wearable device (101) based on identifying that the air pressure change rate and the air pressure change amount satisfy a predefined condition. For example, the wearable device (101) can measure the magnitude of an impact applied to the user of the wearable device (101) using an acceleration sensor, a PPG sensor, and / or a barometric pressure sensor. For example, the wearable device (101) can identify that the user of the wearable device (101) has lost consciousness based on the fact that no movement of the user of the wearable device (101) is identified for a specified period of time using an acceleration sensor, a gyro sensor, and / or a barometric pressure sensor.

[0041] For example, the wearable device (101) can transmit (103) information indicating an emergency situation of the user of the wearable device (101) to an external electronic device (102) via a communication circuit. For example, the wearable device (101) can transmit (103) a signal to notify another predetermined user that the user of the wearable device (101) is in an emergency situation using the external electronic device (102). For example, the wearable device (101) can transmit (103) a signal to the external electronic device (102) to call a designated contact (e.g., an SOS call or an emergency contact).

[0042] For example, the communication circuit of the wearable device (101) can be disabled to cause relatively low power consumption within the wearable device (101).

[0043] For example, the wearable device (101) can activate the communication circuit based on the satisfaction of a condition. For example, the wearable device (101) can activate the communication circuit based on the satisfaction of a condition and transmit (103) information or a signal to an external electronic device (102) using the communication circuit. For example, the wearable device (101) can acquire biometric information of a user of the wearable device (101) while the communication circuit is inactive. For example, the wearable device (101) can store the acquired biometric information of the user of the wearable device (101) in a memory. For example, the wearable device (101) can activate the communication circuit and transmit (103) the biometric information of the user of the wearable device (101) stored in the memory to an external electronic device (102) using the activated communication circuit. For example, even if the communication circuit is disabled, the wearable device (101) may transmit information (103) to an external electronic device (102) without error.

[0044] As a non-limiting example, the wearable device (101) may activate the communication circuit upon identifying a number of biometric information of a user of the wearable device (101) that has reached a reference number. As a non-limiting example, the wearable device (101) may activate the communication circuit upon obtaining information indicating an emergency situation of a user of the wearable device (101).

[0045] For example, the wearable device (101) is not limited to a wearable device (101) configured in a ring shape. For example, a method for reducing power consumption in a wearable device other than a wearable device (101) configured in a ring shape may be required. For example, a wearable device other than a wearable device (101) configured in a ring shape may perform the operations exemplified in the descriptions of FIGS. 4 to 12 . As a non-limiting example, the operations exemplified in the descriptions of FIGS. 4 to 12 may be performed in a smart watch. As a non-limiting example, the operations exemplified in the descriptions of FIGS. 4 to 12 may be performed in a smart watch that is in a power-saving mode.

[0046] For example, the communication circuit may be activated or deactivated depending on whether the wearable device (101) is worn by a user of the wearable device (101). For example, the second sensor may be activated or deactivated depending on whether the wearable device (101) is worn by a user of the wearable device (101). Operations depending on whether the wearable device (101) is worn by a user of the wearable device (101) are exemplified in the description of FIG. 2.

[0047] Figure 2 illustrates an example of reducing power consumption within a wearable device.

[0048] Referring to FIG. 2, the wearable device (101) may be in a state (200) in which it is not worn by a user.

[0049] For example, the wearable device (101) may include a first sensor and a second sensor. For example, the first sensor may be used to detect whether the wearable device (101) is being worn by a user of the wearable device (101). For example, the second sensor may be used to obtain biometric information about the user of the wearable device (101).

[0050] For example, within state (200), the first sensor may be activated. For example, within state (200), the first sensor may be activated to detect whether the wearable device (101) is being worn by a user of the wearable device (101).

[0051] For example, within state (200), the second sensor may be deactivated. For example, within state (200), the second sensor may not be able to obtain biometric information of a user of the wearable device (101). For example, within state (200), the second sensor may not need to measure biometric information of a user of the wearable device (101). For example, within state (200), the second sensor may be deactivated to relatively reduce power consumption within the wearable device (101).

[0052] For example, deactivating the second sensor may include the second sensor not acquiring biometric information of the user of the wearable device (101). For example, the wearable device (101) may continue to provide power to the second sensor without acquiring biometric information of the user of the wearable device (101). For example, the amount of power provided to the second sensor may be reduced by deactivating the second sensor.

[0053] For example, deactivating the second sensor may include ceasing to provide power to the second sensor. For example, deactivating the second sensor may include providing low power to the second sensor. For example, deactivating the second sensor may include turning the second sensor off.

[0054] For example, within state (200), the communication circuit may be activated. For example, within state (200), the wearable device (101) may be wirelessly connected (202) to an external electronic device (102) using the communication circuit. For example, within state (200), the location of the wearable device (101) may not be recognized by the user of the wearable device (101). For example, the communication circuit may be activated to transmit information about the location of the wearable device (101) to the external electronic device (102) via the communication circuit.

[0055] For example, the wearable device (101) may be in a state (203) in which it is worn by a user. For example, within the state (203), the wearable device (101) may be worn on a hand (201) of a user of the wearable device (101). For example, within the state (203), the wearable device (101) may be worn on a part (204) (e.g., a finger) of a hand (201) of a user of the wearable device (101).

[0056] For example, as the wearable device (101) is worn by a user of the wearable device (101), the state (200) may become the state (203).

[0057] For example, within state (203), the first sensor may be activated. For example, within state (203), the first sensor may be activated to detect whether the wearable device (101) is maintained being worn by a user of the wearable device (101). For example, within state (203), the first sensor may be activated to detect that the wearable device (101) is not being worn by a user of the wearable device (101).

[0058] For example, within state (203), the second sensor may be activated. For example, within state (203), the second sensor may be activated to obtain biometric information of a user of the wearable device (101). For example, within state (203), the wearable device (101) may store biometric information of the user of the wearable device (101) obtained through the second sensor in a memory.

[0059] For example, within state (203), the communication circuitry may be disabled. For example, within state (203), the communication circuitry may be disabled to relatively lower the power consumed within the wearable device (101).

[0060] For example, disabling the communication circuit may include disabling a wireless connection from the wearable device (101) to an external electronic device (102). For example, the wearable device (101) may disconnect the wireless connection from the wearable device (101) to the external electronic device (102) and maintain power to the communication circuit. For example, the amount of power provided to the communication circuit may be reduced by disabling the communication circuit.

[0061] For example, disabling a communication circuit may include cessation of power to the communication circuit. For example, disabling a communication circuit may include providing low power to the communication circuit. For example, disabling a communication circuit may include turning the communication circuit off.

[0062] For example, within state (203), the communication circuit may be re-activated if a condition is satisfied. For example, the wearable device (101) may activate the communication circuit and wirelessly connect (205) to an external electronic device (102) using the communication circuit. As a non-limiting example, the wearable device (101) may activate the communication circuit upon identifying a number of biometric information of a user of the wearable device (101) that has reached a reference number. As a non-limiting example, the wearable device (101) may activate the communication circuit upon obtaining information indicating an emergency situation of a user of the wearable device (101).

[0063] For example, a method for reducing power consumption within a wearable device (101) may be implemented within the wearable device (101). For example, the wearable device (101) may include components for implementing such a method. The components of the wearable device (101) are exemplified within the description of FIG. 3.

[0064] Figure 3 is a simplified block diagram of an exemplary wearable device and external electronic devices.

[0065] Referring to FIG. 3, the wearable device (101) may be described as a wearable device (101) configured in a ring shape. For example, the wearable device (101) may be described as a wearable device (101) other than the wearable device (101) configured in a ring shape. The wearable device (101) may include at least a part of the electronic device (1302) of FIG. 13, or may correspond to at least a part of the electronic device (1302) of FIG. 13. For example, the wearable device (101) may include at least one processor (300), a memory (310), a first sensor (320), a second sensor (330), a communication circuit (340), and a rechargeable battery (350). For example, the wearable device (101) may further include a microphone (360) and / or a display (370).

[0066] At least one processor (300) may include processing circuitry. For example, at least one processor (300) may include a central processing unit (CPU) (e.g., including processing circuitry). For example, at least one processor (300) may include a graphic processing unit (GPU) (e.g., including processing circuitry) and a neural processing unit (NPU) (e.g., including processing circuitry). For example, at least one processor (300) may be configured to control a memory (310), a first sensor (320), a second sensor (330), a communication circuit (340), and a rechargeable battery (350). At least one processor (300) may be configured to individually or collectively execute instructions stored in the memory (310) to cause the wearable device (101) to perform at least some of the operations illustrated in the description of FIG. 1 or FIG. 2 . At least one processor (300) may be configured to execute instructions stored in the memory (310) to cause the wearable device (101) to perform at least some of the operations illustrated in the descriptions of FIGS. 4 through 12.

[0067] The memory (310) may include one or more storage media. For example, the memory (310) may store various data used by at least one component of the wearable device (101) (e.g., at least one processor (300), the first sensor (320), and / or the second sensor (330)). For example, the data may include input data or output data for software and commands related thereto. The memory (310) may include volatile memory or non-volatile memory. For example, the memory (310) may include a buffer. For example, the buffer within the memory (310) may be used to store values ​​for biometric information of a user of the wearable device (110).

[0068] The first sensor (320) may be composed of at least one sensor. For example, the first sensor (320) may include at least one of a gesture sensor, a pressure sensor, a proximity sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, and an illuminance sensor. For example, the first sensor (320) may be used to detect whether the wearable device (101) is worn by a user of the wearable device (101).

[0069] The second sensor (330) may be composed of at least one sensor. For example, the second sensor (330) may include at least one of an acceleration sensor, a gyro sensor, a photoplethysmography (PPG) sensor, a pressure sensor, an electrode sensor, a body temperature sensor, a heart rate variability (HRV) sensor, and a blood sugar sensor. For example, the second sensor (330) may be used to obtain values ​​for biometric information of a user of the wearable device (101).

[0070] The communication circuit (340) may support legacy Bluetooth and / or BLE (Bluetooth low energy). For example, the communication circuit (340) may be used for communication with an external electronic device (102). For example, the communication circuit (340) may be used to transmit values ​​of biometric information of a user of the wearable device (101) to the external electronic device (102). For example, the communication circuit (340) may be used to receive a signal regarding an input of a user of the wearable device (101) from the external electronic device (102).

[0071] A rechargeable battery (350) may power at least one component of a wearable device (101). For example, the rechargeable battery (350) may include a rechargeable secondary battery. For example, the rechargeable battery (350) may be integrally disposed within the wearable device (101). For example, the rechargeable battery (350) may be used by at least one processor (300) to identify whether the state of charge (SoC) of the rechargeable battery (350) reaches a threshold SoC.

[0072] The microphone (360) may be configured to capture audio generated in the vicinity of the wearable device (101). For example, the microphone (360) may be used to capture audio corresponding to an input from a user of the wearable device (101). For example, the microphone (360) may be used to identify an input from a user of the wearable device (101) to activate the communication circuit (340).

[0073] The display (370) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the strength of a force generated by the touch. For example, the display (370) may be used to identify an input from a user of the wearable device (101) to activate the communication circuit (340). The external electronic device (102) may be described as a smartphone or tablet for receiving values ​​for biometric information about the user of the wearable device (101). For example, the external electronic device (102) may include at least a portion of the electronic device (1301) of FIG. 13, or may correspond to at least a portion of the electronic device (1301) of FIG. 13. The external electronic device (102) may include at least one processor, memory, display, and communication circuit.

[0074] At least one processor may be configured to control memory, a display, and communication circuitry. The memory may include one or more storage media. The display may be configured to display visual information, visual data, images, and / or a user interface. The display may be used to display biometric information about a user of the wearable device (101). The communication circuitry may support legacy Bluetooth and / or Bluetooth low energy (BLE). The communication circuitry may be used to receive values ​​for biometric information about a user of the wearable device (101).

[0075] The wearable device (101) and the external electronic device (102) illustrated in the description of FIG. 3 can execute at least some of the operations illustrated in the description of FIGS. 4 to 12. For example, the operations illustrated in the description of FIGS. 4 to 12 can be caused by (or within) the wearable device (101) under the control of at least one processor (300).

[0076] FIG. 4 is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit of the wearable device is disabled.

[0077] Referring to FIG. 4, in operation 400, at least one processor (300) may be wirelessly connected to an external electronic device (102) using a communication circuit (340). Operation 410 below may be performed while the wearable device (101) is wirelessly connected to the external electronic device (102).

[0078] In operation 410, at least one processor (300) can detect that the wearable device (101) is worn by a user of the wearable device (101) via a first sensor (320).

[0079] For example, the first sensor (320) may be activated. For example, the first sensor (320) may be activated to detect that the wearable device (101) is being worn by a user of the wearable device (101).

[0080] For example, the second sensor (330) may be disabled to relatively reduce power consumption within the wearable device (101).

[0081] In operation 420, at least one processor (300) may deactivate the communication circuit (340) based on detecting that the wearable device (101) is worn by a user of the wearable device (101) via the first sensor (320).

[0082] For example, at least one processor (300) may disable the communication circuit (340) to relatively lower the power consumed within the wearable device (101).

[0083] For example, deactivating the communication circuit (340) may include disabling a wireless connection from the wearable device (101) to an external electronic device (102). For example, at least one processor (300) may disconnect the wireless connection from the wearable device (101) to the external electronic device (102) and continue to provide power to the communication circuit (340). For example, the amount of power provided to the communication circuit (340) may be reduced by disabling the communication circuit (340).

[0084] For example, deactivating the communication circuit (340) may include ceasing to provide power to the communication circuit (340). For example, deactivating the communication circuit (340) may include providing low power to the communication circuit (340). For example, deactivating the communication circuit (340) may include turning the communication circuit (340) off.

[0085] At least one processor (300) may activate a second sensor (330) based on detecting that the wearable device (101) is being worn by a user of the wearable device (101) via the first sensor (320).

[0086] For example, before the wearable device (101) is worn by a user of the wearable device (101), the second sensor (330) may be in an activated state. For example, at least one processor (300) may keep the second sensor activated.

[0087] For example, before the wearable device (101) is worn by a user of the wearable device (101), the second sensor (330) may be in a deactivated state. For example, at least one processor (300) may activate the second sensor.

[0088] For example, at least one processor (300) may need to obtain values ​​for biometric information of a user of the wearable device (101). For example, at least one processor (300) may activate a second sensor (330) to obtain values ​​for biometric information of a user of the wearable device (101).

[0089] As a non-limiting example, the biometric information of the user of the wearable device (101) may include information about the user's condition. As a non-limiting example, the biometric information of the user of the wearable device (101) may include information about the user's movement. As a non-limiting example, the biometric information of the user of the wearable device (101) may include information about the user's heartbeat. As a non-limiting example, the biometric information of the user of the wearable device (101) may include the regularity or variability of the heartbeat of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the pulse (or change in blood volume in a blood vessel) of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the skin temperature of a part of the body of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the electrodermal activity (EDA) of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the blood sugar level of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the blood sugar level of the user of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the air pressure surrounding the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the acceleration of the wearable device (101). As a non-limiting example, the biometric information of the user of the wearable device (101) may include the angular velocity of the wearable device (101). However, the present invention is not limited thereto.

[0090] For example, at least one processor (300) may acquire a value for biometric information of a user of a wearable device (101) through a second sensor. For example, at least one processor (300) may need to activate a communication circuit to transmit the value for the acquired biometric information to an external electronic device (102) using the communication circuit. The activation of the communication circuit as the values ​​for biometric information stored in a buffer within the memory (310) of the wearable device (101) reach a reference number is exemplified in the description of FIG. 5.

[0091] FIG. 5 is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated as values ​​for stored biometric information in a buffer reach a reference number.

[0092] Referring to FIG. 5, at operation 500, at least one processor (300) may disable the communication circuit (340). Operation 510 below may be performed while the communication circuit (340) is disabled.

[0093] In operation 510, at least one processor (300) may obtain values ​​for biometric information of a user of a wearable device (101) through a second sensor (330). For example, at least one processor (300) may store the values ​​for the obtained biometric information in a buffer within a memory (310).

[0094] In operation 520, at least one processor (300) can identify whether the number of values ​​for the biometric information stored in a buffer in the memory (310) has reached a reference number.

[0095] The number of values ​​for the biometric information stored in the buffer within the memory (310) reaching a reference number is exemplified in the description of FIG. 6.

[0096] Figure 6 illustrates an example in which the number of values ​​for biometric information stored in a buffer reaches a reference number.

[0097] Referring to FIG. 6, at least one processor (300) may store values ​​for biometric information of a user of a wearable device (101) in a buffer (601) within a memory (310). For example, values ​​for biometric information of a user of a wearable device (101) may be temporarily stored in a buffer (601) within a memory (310). For example, the buffer (601) within the memory (310) may be used to store values ​​for biometric information of a user of a wearable device (101) while the communication circuit (340) is inactive. For example, the buffer (601) within the memory (310) may prevent values ​​for biometric information of a user of a wearable device (101) obtained while the communication circuit (340) is inactive from being lost before being transmitted to an external electronic device (102).

[0098] For example, the number of values ​​(602) for biometric information of a user of a wearable device (101) stored in a buffer (601) in a memory (310) may be in a state (600) before reaching a reference number.

[0099] For example, the reference number may be predetermined. For example, the reference number may be determined according to the settings of the user of the wearable device (101). For example, the wearable device (101) may receive a signal for determining the reference number from the external electronic device (102) using the activated communication circuit (340). For example, the reference number may be determined in response to the wearable device (101) receiving a signal for determining the reference number from the external electronic device (102). For example, the reference number may be determined according to the cycle in which at least one processor (300) transmits values ​​for the biometric information of the user of the wearable device (101) to the external electronic device (102).

[0100] For example, within the state (600), the number of values ​​(602) for biometric information of a user of a wearable device (101) stored in a buffer (601) within a memory (310) may be less than a reference number. For example, the state (600) may be a state in which the communication circuit (340) is disabled. For example, the state (600) may correspond to a state before the number of values ​​(602) for biometric information of a user of a wearable device (101) stored in a buffer (601) within a memory (310) reaches a reference number in operation 520 of FIG. 5.

[0101] For example, the number of values ​​(604) for biometric information of a user of a wearable device (101) stored in a buffer (601) in a memory (310) may be in a state (603) that has reached a reference number.

[0102] For example, within the state (603), the number of values ​​(604) for the biometric information of the user of the wearable device (101) stored in the buffer (601) within the memory (310) may be a reference number. For example, the state (603) may be a state before (or immediately before) the communication circuit (340) is activated. For example, the state (603) may correspond to a state in which the number of values ​​(604) for the biometric information of the user of the wearable device (101) stored in the buffer (601) within the memory (310) reaches a reference number in operation 520 of FIG. 5.

[0103] Referring again to FIG. 5, at operation 530, at least one processor (300) may re-activate the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) reaches a reference number.

[0104] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0105] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0106] For example, the number of values ​​for the user's biometric information of the wearable device (101) being transmitted may be a reference number. For example, at least one processor (300) may transmit the values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) to an external electronic device (102).

[0107] For example, at least one processor (300) may activate the communication circuit (340) if the value of the user's biometric information of the wearable device (101) exceeds the reference value, even if the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) is less than a reference number. The activation of the communication circuit (340) when the value of the user's biometric information of the wearable device (101) exceeds the reference value may be described in FIG. 9 below.

[0108] For example, at least one processor (300) may activate the communication circuit (340) when the SoC (state of charge) of the rechargeable battery (350) of the wearable device (101) reaches a threshold SoC, even if the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer of the memory (310) is less than a reference number. The activation of the communication circuit (340) when the SoC (state of charge) of the rechargeable battery (350) of the wearable device (101) reaches the threshold SoC may be described in FIG. 10 below.

[0109] For example, at least one processor (300) may activate the communication circuit (340) when receiving an input from a user of the wearable device (101), even if the number of values ​​for biometric information of the user of the wearable device (101) stored in a buffer within the memory (310) is less than a reference number. The activation of the communication circuit (340) by receiving an input from a user of the wearable device (101) may be described in FIG. 11A below.

[0110] For example, at least one processor (300) may activate the communication circuit (340) if the wearable device (101) is not worn by the user of the wearable device (101), even if the number of values ​​for the user's biometric information stored in the buffer in the memory (310) is less than a reference number. The activation of the communication circuit (340) due to the wearable device (101) not being worn by the user of the wearable device (101) may be described in FIG. 11b below.

[0111] For example, at least one processor (300) may transmit values ​​of biometric information of a user of a wearable device (101) to an external electronic device (102) using a communication circuit (340), and may detect whether the wearable device (101) is worn by a user of the wearable device (101) through a first sensor (320). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by a user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by a user of the wearable device (101).

[0112] For example, at least one processor (300) may re-activate the communication circuit (340) and transmit to the external electronic device (102) based on broadcasting values ​​for the user's biometric information of the wearable device (101). Broadcasting values ​​for the user's biometric information of the wearable device (101) is exemplified within the description of FIG. 7.

[0113] Figure 7 illustrates an example in which values ​​for biometric information are transmitted to an external electronic device based on being broadcast.

[0114] Referring to FIG. 7, at least one processor (300) may broadcast (700) values ​​of biometric information of a user of a wearable device (101) using an activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting (700) values ​​of biometric information of a user of a wearable device (101).

[0115] For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102).

[0116] For example, the number of values ​​for the user's biometric information of the wearable device (101) being broadcasted may be a reference number. For example, at least one processor (300) may broadcast the values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) to an external electronic device (102).

[0117] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the communication circuit (340) and detect whether the wearable device (101) is worn by the user of the wearable device (101) through the first sensor (320). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by the user of the wearable device (101).

[0118] Referring again to FIG. 5, at operation 540, at least one processor (300) may keep the communication circuit (340) inactive until the number of values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) reaches a reference number.

[0119] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from, or not perform transmission) transmitting values ​​for biometric information of a user of a wearable device (101) stored in a buffer in a memory (310) to an external electronic device (102) until the number of values ​​for biometric information of a user of a wearable device (101) stored in a buffer in a memory (310) reaches a reference number.

[0120] For example, at least one processor (300) may activate the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated, even if the number of values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) is less than a reference number. The activation of the communication circuit upon the elapse of the reference time is exemplified in the description of FIG. 8.

[0121] FIG. 8 is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated over a period of time.

[0122] Referring to FIG. 8, at operation 800, at least one processor (300) may disable the communication circuit (340). Operation 810 below may be performed while the communication circuit (340) is disabled.

[0123] In operation 810, at least one processor (300) may obtain values ​​for biometric information of a user of a wearable device (101) through a second sensor (330). For example, at least one processor (300) may store the values ​​for the obtained biometric information in a buffer within a memory (310).

[0124] At operation 820, at least one processor (300) may identify whether a reference time has elapsed since the communication circuit (340) was inactive.

[0125] For example, the reference time may be predetermined. For example, the reference time may be determined according to the settings of the user of the wearable device (101). For example, the wearable device (101) may receive a signal for determining the reference time from an external electronic device (102) using the activated communication circuit (340). For example, the reference time may be determined in response to the wearable device (101) receiving a signal for determining the reference time from the external electronic device (102). For example, the reference time may be determined according to a cycle in which at least one processor (300) transmits values ​​for the biometric information of the user of the wearable device (101) to the external electronic device (102).

[0126] At operation 830, at least one processor (300) may re-enable the communication circuit (340) if a reference time has elapsed since the communication circuit (340) was deactivated.

[0127] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0128] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting the values ​​of biometric information of a user of the wearable device (101).

[0129] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0130] For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102).

[0131] For example, the values ​​of the user's biometric information of the wearable device (101) being transmitted (or broadcasted) may be values ​​of the user's biometric information of the wearable device (101) acquired during a reference time since the communication circuit (340) was deactivated. For example, at least one processor (300) may transmit (or broadcast) to an external electronic device (102) the values ​​of the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) during a reference time since the communication circuit (340) was deactivated.

[0132] For example, at least one processor (300) may activate the communication circuit (340) if a value of the user's biometric information of the wearable device (101) exceeds a reference value, even if a reference time has not elapsed since the communication circuit (340) was deactivated. The activation of the communication circuit (340) when a value of the user's biometric information of the wearable device (101) exceeds a reference value may be described in FIG. 9 below.

[0133] For example, at least one processor (300) may activate the communication circuit (340) when the state of charge (SoC) of the rechargeable battery (350) of the wearable device (101) reaches a threshold SoC, even if a reference time has not elapsed since the communication circuit (340) was deactivated. The activation of the communication circuit (340) when the state of charge (SoC) of the rechargeable battery (350) of the wearable device (101) reaches the threshold SoC may be described in FIG. 10 below.

[0134] For example, at least one processor (300) may activate the communication circuit (340) when receiving an input from a user of the wearable device (101), even if a reference time has not elapsed since the communication circuit (340) was deactivated. Activation of the communication circuit (340) by receiving an input from a user of the wearable device (101) may be described in FIG. 11a below. For example, at least one processor (300) may activate the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101), even if a reference time has not elapsed since the communication circuit (340) was deactivated. Activation of the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101) may be described in FIG. 11b below.

[0135] For example, at least one processor (300) may transmit (or broadcast) values ​​for biometric information of a user of the wearable device (101) to an external electronic device (102) using the communication circuit (340), and may detect, through the first sensor (320), whether the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by the user of the wearable device (101).

[0136] In operation 840, at least one processor (300) may keep the communication circuit (340) disabled until a reference time has elapsed since the communication circuit (340) was disabled.

[0137] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from transmitting) values ​​for biometric information of a user of a wearable device (101) stored in a buffer within a memory (310) to an external electronic device (102) until a reference time has elapsed since the communication circuit (340) was deactivated.

[0138] For example, even if a reference time has not elapsed since at least one processor (300) communication circuit (340) was deactivated, if a value for the user's biometric information of the wearable device (101) exceeds a reference value, the communication circuit (340) may be activated. The activation of the communication circuit when the value for the user's biometric information of the wearable device (101) exceeds a reference value is exemplified in the description of FIG. 9.

[0139] FIG. 9 is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated when a value for biometric information exceeds a reference value.

[0140] Referring to FIG. 9, at operation 900, at least one processor (300) may disable the communication circuit (340). Operation 910 below may be performed while the communication circuit (340) is disabled.

[0141] In operation 910, at least one processor (300) may obtain values ​​for biometric information of a user of a wearable device (101) through a second sensor (330). For example, at least one processor (300) may store the values ​​for the obtained biometric information in a buffer within a memory (310).

[0142] In operation 920, at least one processor (300) can identify whether a value of biometric information of a user of the wearable device (101) exceeds a reference value.

[0143] For example, the reference value may be predetermined. For example, the reference value may be determined according to the settings of the user of the wearable device (101). For example, the wearable device (101) may receive a signal for determining the reference value from the external electronic device (102) using the activated communication circuit (340). For example, the reference value may be determined in response to the wearable device (101) receiving a signal for determining the reference value from the external electronic device (102). For example, a value for the biometric information of the user of the wearable device (101) exceeding the reference value may be obtained when the user of the wearable device (101) is in an emergency situation. For example, at least one processor (300) may determine the reference value to identify that the user of the wearable device (101) is in an emergency situation.

[0144] As a non-limiting example, the reference value may include a predetermined acceleration value of the wearable device (101). As a non-limiting example, the reference value may include a value for the pulse (or change in blood volume in a blood vessel) of a user of the wearable device (101). As a non-limiting example, the reference value may include a predetermined blood sugar level value of a user of the wearable device (101). As a non-limiting example, the reference value may include a value for the air pressure around the wearable device (101). However, the present invention is not limited thereto.

[0145] In operation 930, at least one processor (300) may re-activate the communication circuit (340) if the value of the user's biometric information of the wearable device (101) exceeds a reference value.

[0146] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0147] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting the values ​​of biometric information of a user of the wearable device (101).

[0148] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0149] For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102).

[0150] For example, the values ​​of the user's biometric information of the wearable device (101) being transmitted (or broadcasted) may be values ​​of the user's biometric information of the wearable device (101) acquired during a time period between the time when the communication circuit (340) is deactivated and the time when the communication circuit (340) is activated. For example, at least one processor (300) may transmit (or broadcast) to an external electronic device (102) the values ​​of the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) during a time period between the time when the communication circuit (340) is deactivated and the time when the communication circuit (340) is activated.

[0151] For example, at least one processor (300) may activate the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches the reference number, even if the value for the user's biometric information of the wearable device (101) does not exceed the reference number. The activation of the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches the reference number may be referenced within the description of FIG. 5.

[0152] For example, at least one processor (300) may activate the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated, even if the value of the user's biometric information of the wearable device (101) does not exceed a reference value. The activation of the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated may be referenced within the description of FIG. 8.

[0153] For example, at least one processor (300) may activate the communication circuit (340) when the SoC (state of charge) of the rechargeable battery (350) of the wearable device (101) reaches a threshold SoC, even if the value of the biometric information of the user of the wearable device (101) does not exceed a reference value. The activation of the communication circuit (340) when the SoC (state of charge) of the rechargeable battery (350) of the wearable device (101) reaches the threshold SoC may be described in FIG. 10 below.

[0154] For example, at least one processor (300) may activate the communication circuit (340) upon receiving an input from a user of the wearable device (101), even if the value of the user's biometric information of the wearable device (101) does not exceed a reference value. The activation of the communication circuit (340) by receiving an input from a user of the wearable device (101) may be described in FIG. 11A below.

[0155] For example, at least one processor (300) may activate the communication circuit (340) if the wearable device (101) is not worn by the user of the wearable device (101), even if the value of the user's biometric information of the wearable device (101) does not exceed a reference value. The activation of the communication circuit (340) due to the wearable device (101) not being worn by the user of the wearable device (101) may be described in FIG. 11b below.

[0156] For example, at least one processor (300) may transmit (or broadcast) values ​​for biometric information of a user of the wearable device (101) to an external electronic device (102) using the communication circuit (340), and may detect, through the first sensor (320), whether the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by the user of the wearable device (101).

[0157] In operation 940, at least one processor (300) may keep the communication circuit (340) disabled until a value for the user's biometric information of the wearable device (101) exceeds a reference value.

[0158] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from transmitting, or not transmit) values ​​of biometric information of a user of the wearable device (101) stored in a buffer in the memory (310) to an external electronic device (102) until the values ​​of biometric information of the user of the wearable device (101) exceed a reference value.

[0159] For example, even if the value of the biometric information of the user of the wearable device (101) of at least one processor (300) does not exceed a reference value, the communication circuit (340) can be activated when the rechargeable battery (350) of the wearable device (101) reaches a critical SoC (state of charge). The activation of the communication circuit when the SoC (state of charge) of the rechargeable battery (350) of the wearable device (101) reaches the critical SoC is exemplified in the description of FIG. 10.

[0160] FIG. 10 is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated as the SoC of the battery reaches a critical SoC.

[0161] Referring to FIG. 10, at operation 1000, at least one processor (300) may disable the communication circuit (340). Operation 1010 below may be performed while the communication circuit (340) is disabled.

[0162] In operation 1010, at least one processor (300) may obtain values ​​for biometric information of a user of a wearable device (101) through a second sensor (330). For example, at least one processor (300) may store the values ​​for the obtained biometric information in a buffer within a memory (310).

[0163] In operation 1020, at least one processor (300) may identify whether the SoC of the rechargeable battery (350) has reached a threshold SoC.

[0164] For example, the threshold SoC may be predetermined. For example, the threshold SoC may be determined according to a user's setting of the wearable device (101). For example, the wearable device (101) may receive a signal for determining the threshold SoC from an external electronic device (102) using the activated communication circuit (340). For example, the threshold SoC may be determined in response to the wearable device (101) receiving a signal for determining the threshold SoC from the external electronic device (102). In operation 1030, at least one processor (300) may re-enable the communication circuit (340) when the SoC of the rechargeable battery (350) reaches the threshold SoC.

[0165] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0166] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting the values ​​of biometric information of a user of the wearable device (101).

[0167] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0168] For example, a state in which the rechargeable battery (350) is at a critical SoC may be a state in which the SoC of the rechargeable battery (350) is relatively low. For example, in a state in which the rechargeable battery (350) is at a critical SoC, a method for reducing power consumption within the wearable device (101) may be required. For example, values ​​for biometric information of a user of the wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of the wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102). For example, at least one processor (300) may broadcast values ​​for biometric information of a user of the wearable device (101) using the communication circuit (340) and then deactivate the communication circuit again.

[0169] For example, the values ​​of the user's biometric information of the wearable device (101) being transmitted (or broadcasted) may be values ​​of the user's biometric information of the wearable device (101) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340). For example, at least one processor (300) may transmit (or broadcast) to the external electronic device (102) the values ​​of the user's biometric information of the wearable device (101) stored in a buffer in the memory (310) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340).

[0170] For example, at least one processor (300) may activate the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches a reference number, even if the SoC of the rechargeable battery (350) does not reach a critical SoC. The activation of the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches a reference number may be referenced within the description of FIG. 5.

[0171] For example, at least one processor (300) may activate the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated, even if the SoC of the rechargeable battery (350) has not reached a critical SoC. The activation of the communication circuit (340) when the reference time has elapsed since the communication circuit (340) was deactivated may be referenced within the description of FIG. 8.

[0172] For example, at least one processor (300) may activate the communication circuit (340) when a value of the user's biometric information of the wearable device (101) exceeds a reference value, even if the SoC of the rechargeable battery (350) does not reach a threshold SoC. The activation of the communication circuit (340) when the value of the user's biometric information of the wearable device (101) exceeds a reference value may be referenced within the description of FIG. 9.

[0173] For example, at least one processor (300) may activate the communication circuit (340) when receiving an input from a user of the wearable device (101), even if the SoC of the rechargeable battery (350) does not reach a threshold SoC. The activation of the communication circuit (340) by receiving an input from a user of the wearable device (101) may be described in FIG. 11a below. For example, at least one processor (300) may activate the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101), even if the SoC of the rechargeable battery (350) does not reach a threshold SoC. The activation of the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101) may be described in FIG. 11b below.

[0174] For example, at least one processor (300) may transmit (or broadcast) values ​​for biometric information of a user of the wearable device (101) to an external electronic device (102) using the communication circuit (340), and may detect, through the first sensor (320), whether the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by the user of the wearable device (101).

[0175] At operation 1040, at least one processor (300) may keep the communication circuit (340) disabled until the SoC of the rechargeable battery (350) reaches a threshold SoC.

[0176] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from transmitting, or not transmit) values ​​for biometric information of a user of a wearable device (101) stored in a buffer in a memory (310) to an external electronic device (102) until the SoC of the rechargeable battery (350) reaches a threshold SoC.

[0177] For example, even if the SoC of at least one processor (300) rechargeable battery (350) does not reach the critical SoC, the communication circuit (340) can be activated when receiving an input from a user of the wearable device (101). Activation of the communication circuit by receiving an input from a user of the wearable device (101) is exemplified in the description of FIG. 11A. For example, even if the SoC of at least one processor (300) rechargeable battery (350) does not reach the critical SoC, the communication circuit (340) can be activated when detecting that the wearable device (101) is not worn by the user of the wearable device (101). Activation of the communication circuit by detecting that the wearable device (101) is not worn by the user of the wearable device (101) is exemplified in the description of FIG. 11B.

[0178] FIG. 11A is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated by input from a user of the wearable device.

[0179] FIG. 11B is a flowchart illustrating exemplary operations of a wearable device in which a communication circuit is activated when the wearable device is not worn by a user of the wearable device.

[0180] Referring to FIGS. 11A and 11B , at operation 1100, at least one processor (300) may disable the communication circuit (340). Operation 1110 below may be performed while the communication circuit (340) is disabled.

[0181] In operation 1110, at least one processor (300) may obtain values ​​for biometric information of a user of a wearable device (101) through a second sensor (330). For example, at least one processor (300) may store the values ​​for the obtained biometric information in a buffer within a memory (310).

[0182] Referring to FIG. 11A, in operation 1115, at least one processor (300) may receive an input from a user of the wearable device (101). For example, the input from the user of the wearable device (101) may be an input for activating the communication circuit (300).

[0183] For example, at least one processor (300) may receive an input from a user of the wearable device (101) through a second sensor (330). For example, the second sensor (330) may be used to identify a gesture corresponding to an input from a user of the wearable device (101). For example, the gesture corresponding to an input from a user of the wearable device (101) may be predetermined. For example, the gesture corresponding to an input from a user of the wearable device (101) may be determined by a setting of the user of the wearable device (101). For example, the wearable device (101) may receive a signal from an external electronic device (102) using an activated communication circuit (340) to determine a gesture corresponding to an input from a user of the wearable device (101). For example, a gesture corresponding to a user input of a wearable device (101) may be determined in response to the wearable device (101) receiving a signal from an external electronic device (102) that determines a gesture corresponding to the user input of the wearable device (101). For example, at least one processor (300) may receive an input of a user of the wearable device (101) based on identifying a gesture corresponding to the user input of the wearable device (101).

[0184] For example, at least one processor (300) may receive an input from a user of the wearable device (101) via a microphone (360). For example, the microphone (360) may be used to obtain audio corresponding to an input from a user of the wearable device (101). For example, the audio corresponding to an input from a user of the wearable device (101) may be predetermined. For example, the audio corresponding to an input from a user of the wearable device (101) may be determined by a setting of the user of the wearable device (101). For example, the wearable device (101) may receive a signal from an external electronic device (102) using an activated communication circuit (340) to determine an audio corresponding to an input from a user of the wearable device (101). For example, audio corresponding to a user's input of the wearable device (101) may be determined in response to the wearable device (101) receiving a signal from an external electronic device (102) that determines audio corresponding to the user's input of the wearable device (101). For example, at least one processor (300) may receive an input of the user of the wearable device (101) based on obtaining audio corresponding to the user's input of the wearable device (101).

[0185] For example, at least one processor (300) can receive an input from a user of the wearable device (101) through the display (370). For example, a microphone (360) can be used to detect a touch corresponding to an input from a user of the wearable device (101). For example, a touch corresponding to an input from a user of the wearable device (101) can be predetermined. For example, a touch corresponding to an input from a user of the wearable device (101) can be determined by a setting of the user of the wearable device (101). For example, the wearable device (101) can receive a signal from an external electronic device (102) using an activated communication circuit (340) to determine a touch corresponding to an input from a user of the wearable device (101). For example, a touch corresponding to a user input of a wearable device (101) may be determined in response to the wearable device (101) receiving a signal from an external electronic device (102) that determines a touch corresponding to the user input of the wearable device (101). For example, at least one processor (300) may receive a user input of the wearable device (101) based on detecting a touch corresponding to the user input of the wearable device (101).

[0186] At operation 1125, at least one processor (300) may re-enable the communication circuit (340) upon receiving user input.

[0187] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0188] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting the values ​​of biometric information of a user of the wearable device (101).

[0189] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0190] For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102).

[0191] For example, the values ​​of the user's biometric information of the wearable device (101) being transmitted (or broadcasted) may be values ​​of the user's biometric information of the wearable device (101) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340). For example, at least one processor (300) may transmit (or broadcast) to the external electronic device (102) the values ​​of the user's biometric information of the wearable device (101) stored in a buffer in the memory (310) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340).

[0192] For example, even if at least one processor (300) does not receive an input from a user of the wearable device (101), the communication circuit (340) may be activated when the number of values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) reaches a reference number. The activation of the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in a buffer within the memory (310) reaches a reference number may be referenced within the description of FIG. 5.

[0193] For example, at least one processor (300) may activate the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated, even if the processor (300) does not receive input from a user of the wearable device (101). The activation of the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated may be referenced within the description of FIG. 8.

[0194] For example, at least one processor (300) may activate the communication circuit (340) when a value of the user's biometric information of the wearable device (101) exceeds a reference value, even if the processor (300) does not receive an input from the user of the wearable device (101). The activation of the communication circuit (340) when the value of the user's biometric information of the wearable device (101) exceeds a reference value may be referenced within the description of FIG. 9.

[0195] For example, at least one processor (300) may activate the communication circuit (340) when the SoC of the rechargeable battery (350) reaches a threshold SoC, even if the processor (300) does not receive input from a user of the wearable device (101). The activation of the communication circuit (340) when the SoC of the rechargeable battery (350) reaches the threshold SoC may be referenced within the description of FIG. 10.

[0196] For example, at least one processor (300) may activate the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101), even if the processor (300) does not receive input from the user of the wearable device (101). The activation of the communication circuit (340) when the wearable device (101) is not worn by the user of the wearable device (101) may be described in FIG. 11b below.

[0197] For example, at least one processor (300) may transmit (or broadcast) values ​​for biometric information of a user of the wearable device (101) to an external electronic device (102) using the communication circuit (340), and may detect, through the first sensor (320), whether the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may deactivate the communication circuit (340) again based on detecting that the wearable device (101) is worn by the user of the wearable device (101). For example, at least one processor (300) may keep the communication circuit (340) activated based on detecting that the wearable device (101) is not worn by the user of the wearable device (101).

[0198] At operation 11135, at least one processor (300) may keep the communication circuit (340) disabled until receiving user input.

[0199] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from transmitting, or not transmit) values ​​of the user's biometric information of the wearable device (101) stored in a buffer in the memory (310) to the external electronic device (102) until receiving a user's input. Referring to FIG. 11B, in operation 1120, at least one processor (300) may detect, via the first sensor (320), whether the wearable device (101) is worn by the user of the wearable device (101).

[0200] At operation 1130, at least one processor (300) may re-enable the communication circuit (340) if it detects through the first sensor (320) that the wearable device (101) is not being worn by the user of the wearable device (101).

[0201] For example, the wearable device (101) may be set to be taken off by the user of the wearable device (101) so that the user of the wearable device (101) intentionally transmits values ​​for the user's biometric information of the wearable device (101) to the external electronic device (102). For example, the user of the wearable device (101) may cause the communication circuit (340) to be activated by taking off the wearable device (101). For example, the user of the wearable device (101) may cause the values ​​for the user's biometric information of the wearable device (101) to be transmitted to the external electronic device (102).

[0202] For example, at least one processor (300) may transmit values ​​for biometric information of a user of a wearable device (101) to an external electronic device (102) using an activated communication circuit (340).

[0203] For example, at least one processor (300) may broadcast values ​​of biometric information of a user of the wearable device (101) using the activated communication circuit (340). For example, at least one processor (300) may transmit the values ​​to an external electronic device based on broadcasting the values ​​of biometric information of a user of the wearable device (101).

[0204] For example, at least one processor (300) can establish a communication link between the wearable device (101) and an external electronic device (102) using the communication circuit (340). For example, at least one processor (300) can transmit values ​​for biometric information of a user of the wearable device (101) to the external electronic device (102) through the communication link between the wearable device (101) and the external electronic device (102).

[0205] For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast before a communication link is established between the wearable device (101) and an external electronic device (102). For example, values ​​for biometric information of a user of a wearable device (101) may be broadcast without a communication link being established between the wearable device (101) and an external electronic device (102).

[0206] For example, the values ​​of the user's biometric information of the wearable device (101) being transmitted (or broadcasted) may be values ​​of the user's biometric information of the wearable device (101) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340). For example, at least one processor (300) may transmit (or broadcast) to the external electronic device (102) the values ​​of the user's biometric information of the wearable device (101) stored in a buffer in the memory (310) that are not transmitted to the external electronic device (102) by disabling the communication circuit (340).

[0207] For example, even if at least one processor (300) does not detect through the first sensor (320) that the wearable device (101) is not being worn by the user of the wearable device (101), the communication circuit (340) may be activated when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches a reference number. The activation of the communication circuit (340) when the number of values ​​for the user's biometric information of the wearable device (101) stored in the buffer within the memory (310) reaches a reference number may be referenced within the description of FIG. 5.

[0208] For example, at least one processor (300) may activate the communication circuit (340) when a reference time has elapsed since the communication circuit (340) was deactivated, even if the first sensor (320) does not detect that the wearable device (101) is not being worn by the user of the wearable device (101). The activation of the communication circuit (340) when the reference time has elapsed since the communication circuit (340) was deactivated may be referenced within the description of FIG. 8.

[0209] For example, at least one processor (300) may activate the communication circuit (340) if a value of the user's biometric information of the wearable device (101) exceeds a reference value, even if the first sensor (320) does not detect that the wearable device (101) is not being worn by the user of the wearable device (101). The activation of the communication circuit (340) when the value of the user's biometric information of the wearable device (101) exceeds a reference value may be referenced within the description of FIG. 9.

[0210] For example, at least one processor (300) may activate the communication circuit (340) when the state of charge (SoC) of the rechargeable battery (350) of the wearable device (101) reaches a threshold SoC, even if the first sensor (320) does not detect that the wearable device (101) is not being worn by the user of the wearable device (101). The activation of the communication circuit (340) when the state of charge (SoC) of the rechargeable battery (350) of the wearable device (101) reaches the threshold SoC may be referenced within the description of FIG. 10.

[0211] For example, at least one processor (300) may activate the communication circuit (340) upon receiving a user's input, even if the first sensor (320) does not detect that the wearable device (101) is not being worn by the user of the wearable device (101). Activation of the communication circuit (340) upon receiving a user's input may be referenced within the description of FIG. 11A. In operation 1140, the at least one processor (300) may maintain the deactivation of the communication circuit (340) until the first sensor (320) detects that the wearable device (101) is not being worn by the user of the wearable device (101).

[0212] For example, at least one processor (300) may bypass (or skip, or delay, or refrain from transmitting, or not transmit) values ​​for biometric information of a user of the wearable device (101) stored in a buffer in the memory (310) to an external electronic device (102) until the first sensor (320) detects that the wearable device (101) is not being worn by a user of the wearable device (101).

[0213] For example, at least one processor (300) may detect that the wearable device (101) is not being worn by a user of the wearable device (101) through the first sensor (320) and deactivate the second sensor (330). Deactivating the second sensor (330) and activating the communication circuit (340) is exemplified within the description of FIG. 12.

[0214] FIG. 12 is a flowchart illustrating exemplary operations of a wearable device in which a second sensor is deactivated and a communication circuit is activated when the wearable device is not worn by a user of the wearable device.

[0215] Referring to FIG. 12, in operation 1200, at least one processor (300) may detect, through the first sensor (320), that the wearable device (101) is not worn by the user of the wearable device (101). For example, a state in which the wearable device (101) is not worn by the user of the wearable device (101) may correspond to the state (200) of FIG. 2.

[0216] For example, the time point at which it is detected through the first sensor (320) that the wearable device (101) is not being worn by the user of the wearable device (101) may be after (or immediately after) the wearable device (101) is taken off by the user of the wearable device (101). For example, the time point may be after (or immediately after) the state (203) of FIG. 2 is changed to the state (200). For example, at the time point, the wearable device (101) may be caused by the user of the wearable device (101) to transmit values ​​for the biometric information of the user of the wearable device (101) to the external electronic device (102).

[0217] For example, the time point at which it is detected through the first sensor (320) that the wearable device (101) is not being worn by the user of the wearable device (101) may be before the wearable device (101) is worn by the user of the wearable device (101). For example, at the time point, the location of the wearable device (101) may not be recognized by the user of the wearable device (101). For example, at the time point, at least one processor (300) needs to transmit information about the location of the wearable device (101) to the external electronic device (102) using the communication circuit (340).

[0218] In operation 1210, at least one processor (300) may deactivate the second sensor (330). For example, if the wearable device (101) is not worn by the user of the wearable device (101), the second sensor (330) may not be able to obtain biometric information of the user of the wearable device (101). For example, if the wearable device (101) is not worn by the user of the wearable device (101), the second sensor (330) may not need to measure biometric information of the user of the wearable device (101). For example, the second sensor (330) may be deactivated to relatively lower power consumption within the wearable device (101).

[0219] For example, deactivating the second sensor (330) may include the second sensor (330) not obtaining a value for biometric information of a user of the wearable device (101). For example, at least one processor (300) may continue to provide power to the second sensor (330) without obtaining a value for biometric information of a user of the wearable device (101). For example, the amount of power provided to the second sensor (330) may be reduced by deactivating the second sensor (330).

[0220] For example, deactivating the second sensor (330) may include ceasing to provide power to the second sensor (330). For example, deactivating the second sensor (330) may include providing low power to the second sensor (330). For example, deactivating the second sensor (330) may include turning the second sensor (330) off.

[0221] For example, at least one processor (300) can activate a communication circuit (340).

[0222] For example, when the wearable device (101) is not worn by a user of the wearable device (101), the wearable device (101) can be wirelessly connected to an external electronic device (102) using the communication circuit (340).

[0223] For example, if the wearable device (101) is taken off by the user of the wearable device (101) (or immediately after), the communication circuit (340) may be activated to transmit values ​​for the biometric information of the user of the wearable device (101) to the external electronic device (102).

[0224] For example, if the wearable device (101) is not worn by a user of the wearable device (101), the location of the wearable device (101) may not be recognized by the user of the wearable device (101). For example, the communication circuit (340) may be activated to transmit information about the location of the wearable device (101) to an external electronic device (102) through the communication circuit.

[0228] The auxiliary processor (1323) may control at least a portion of functions or states associated with at least one component (e.g., the display module (1360), the sensor module (1376), or the communication module (1390)) of the electronic device (1301), for example, on behalf of the main processor (1321) while the main processor (1321) is in an inactive (e.g., sleep) state, or together with the main processor (1321) while the main processor (1321) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (1323) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (1380) or a communication module (1390)). In one embodiment, the auxiliary processor (1323) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (1301) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (1308)).

The communication module (1390) may operate independently from the processor (1320) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (1390) may include a wireless communication module (1392) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (1394) (e.g., a local area network (LAN) communication module, or a power line communication module). Any of these communication modules may communicate with an external electronic device (1304) via a first network (1398) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (1399) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a local area network or a wide area network)). These various types of communication modules may 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 (1392) may use subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (1396) to verify or authenticate the electronic device (1301) within a communication network such as the first network (1398) or the second network (1399).

[0243] The wireless communication module (1392) 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 communications (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (1392) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (1392) can support various technologies for securing performance in high-frequency bands, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (1392) can support various requirements specified in the electronic device (1301), an external electronic device (e.g., the electronic device (1304)), or a network system (e.g., the second network (1399)). According to one embodiment, the wireless communication module (1392) may support a peak data rate (e.g., 20 Gbps or more) for eMBB implementation, a loss coverage (e.g., 164 dB or less) for mMTC implementation, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC implementation.

In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (1398) or the second network (1399), may be selected from the plurality of antennas by, for example, the communication module (1390). A signal or power may be transmitted or received between the communication module (1390) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (1397).

[0245] According to various embodiments, the antenna module (1397) may form a mmWave antenna module.

[0246] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0247] According to one embodiment, commands or data may be transmitted or received between the electronic device (1301) and an external electronic device (1304) via a server (1308) connected to a second network (1399). Each of the external electronic devices (1302 or 1304) may be the same or a different type of device as the electronic device (1301). According to one embodiment, all or part of the operations executed in the electronic device (1301) may be executed in one or more of the external electronic devices (1302, 1304, or 1308). For example, when the electronic device (1301) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1301) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1301). The electronic device (1301) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example.

[0254] FIG. 14A illustrates a perspective view of an exemplary electronic device according to one embodiment.

[0255] Referring to FIG. 14A, a wearable device (101) (e.g., the wearable device (101) of FIG. 3) may include a housing (1401) that includes a first side (1411) facing a part of a user's body (e.g., a finger) and a second side (1412) opposite the first side (1411). For example, the wearable device (101) may include a ring-shaped housing (1401). For example, the wearable device (101) may be configured in a ring shape.

[0256] For example, the wearable device (101) may be referred to as a wearable device that can be worn by a user. The wearable device (101) may be worn on a part of the user's body (e.g., a finger). For example, the wearable device (101) may be worn on a part of the user's body. For example, the wearable device (101) may be fastened to a part of the user's body. For example, the wearable device (101) may be detachable from a part of the user's body. For example, the wearable device (101) may have a shape corresponding to a part of the user's body in order to be worn on a part of the user's body.

[0257] For example, the wearable device (101) may be worn by the user and thus come into contact with a part of the user's body. For example, the wearable device (101) may be configured to obtain information about the user through a part of the user's body by being worn by the user. For example, the information about the user may include the user's health information. However, the present invention is not limited thereto. For example, the wearable device (101) may provide information about the user through the wearable device (101) and / or an external electronic device connected to the wearable device (101). However, the present invention is not limited thereto.

[0258] For example, at least a portion of the first surface (1411) may come into contact with a part of the user's body when the wearable device (101) is worn by the user. For example, the first surface (1411) may surround a part of the user's body on which the wearable device (101) is worn. For example, the first surface (1411) may cover a part of the user's body on which the wearable device (101) is worn. For example, the first surface (1411) may be configured to pressurize a part of the user's body when the wearable device (101) is worn by the user, thereby fastening the wearable device (101) to the part of the body. For example, the first surface (1411) may be deformable by a part of the user's body. For example, the wearable device (101) can provide information about the user through the first surface (1411) based on haptic technology.

[0259] For example, the second surface (1412) may form an outer appearance of the wearable device (101) together with the first surface (1411). For example, the second surface (1412) may form a ring-shaped housing (1401) together with the first surface (1411). For example, the second surface (1412) may be a surface that is spaced apart from a part of the user's body when the wearable device (101) is worn by the user. For example, the first surface (1411) may be referred to as an inner circumference surface of the housing (1401). The second surface (1412) opposite to the first surface (1411) may be referred to as an outer circumference surface of the housing (1401).

[0260] For example, the second surface (1412) may be exposed to the outside when the wearable device (101) is worn by the user. The second surface (1412) may be composed of at least one of titanium, stainless steel, and ceramic. The second surface (1412) may be composed of a material for protection against external impact and / or scratches. For example, the second surface (1412) may be coated with an additional material for protection of the color and / or appearance of the wearable device (101).

[0261] For example, the first side (1411) may be composed of the same and / or similar material as the second side (1412). For example, at least a portion of the first side (1411) may be composed of at least one of a molding material for acquiring data, transparent plastic, and / or glass. For example, at least a portion of the first side (1411) may be composed of a metal for identifying a biosignal.

[0262] For example, the wearable device (101) may further include a hole (1470) formed by the first surface (1411) for passing a part of the user's body through the wearable device (101) when the wearable device (101) is worn by the user. For example, the hole (1470) may be penetrated by a part of the user's body when the wearable device (101) is worn by the user. The wearable device (101) may be configured to be fastened to a part of the user's body when the user wears the wearable device (101) by including a hole (1470) configured to pass a part of the user's body through the hole.

[0263] For example, the wearable device (101) may further include one or more components between the first side (1411) and the second side (1412). For example, the wearable device (101) may include a communication circuit, one or more sensors, and / or a processor between the first side (1411) and the second side (1412). The arrangement of the one or more components will be described later in FIG. 14B.

[0264] FIG. 14b is an example of a partial cross-sectional view of an electronic device according to one embodiment.

[0265] Referring to FIG. 14B, the wearable device (101) may be formed in a ring shape. For example, the housing (1401) of the wearable device (101) may be formed in a ring shape that can be worn on a user's finger. In FIGS. 14A and 14B, a wearable device (101) having a ring shape with a smooth surface is illustrated as an example, but the present invention is not limited thereto. For example, the wearable device (101) may be implemented as a housing including a plurality of flat surfaces. For example, a wearable device (101) having a ring shape with an unsmooth surface may also be understood as an embodiment of the present disclosure.

[0266] For example, a ring-shaped housing (1401) may include a first side (1411) that comes into contact with a user's body when worn by the user, a second side (1412) that is exposed to the outside, and a side surface between the first side (1411) and the second side (1412). For example, a space may be included between the first side (1411) and the second side (1412) to include (or place) at least one component (e.g., at least one processor (300), a memory (310), a first sensor (320), a second sensor (330), a communication circuit (340), and a rechargeable battery (350)).

[0267] For example, a PCB may be placed between the first side (1411) and the second side (1412) of the wearable device (101). For example, at least one processor (1410), a communication circuit (1420), an acceleration sensor, a gyro sensor, a PPG sensor, a temperature sensor, a memory (1440), and / or a PMIC (1454) may be placed on the PCB (1451). For example, the PCB (1451) may be composed of a rigid region and a flexible region. For example, the rigid region may be referred to as a rigid flexible printed circuit board (RFPCB). For example, the flexible region may be referred to as a flexible printed circuit board (FPCB).

[0268] For example, a PPG sensor may include one or more light-emitting circuits (1433-1), one or more light-receiving circuits (1433-2), and a control circuit (1433-3). For example, the one or more light-emitting circuits (1433-1) and the one or more light-receiving circuits (1433-2) may be arranged toward the first side (1411). For example, the control circuit (1433-3) may be arranged toward the second side (1412).

[0269] For example, the PMIC (1454) can be used to manage power of the wearable device (101). The PMIC (1454) can be used to provide (or distribute) power to components that require power in the wearable device (101). The PMIC (1454) can support a wired charging method (e.g., terminal, pogo pin) or a wireless charging method (e.g., wireless power consortium (WPC), NFC) for charging the wearable device (101) through the charging interface (1453).

[0270] For example, a battery (1452) may be placed between the first side (1411) and the second side (1412) of the wearable device (101). The battery (1452) may be configured with at least one battery (or battery pack). For example, the battery (1452) may be configured such that at least one battery is connected in series and / or in parallel. For example, the battery (1452) may be configured as a flexible battery pack. For example, the battery (1452) may be charged and / or discharged as a secondary battery. For example, the material constituting the battery (1452) may be configured in various ways. For example, the material constituting the battery (1452) may include at least one of lithium ion and mercury.

[0271] For example, an antenna (1455) may be positioned between a first side (1411) and a second side (1412) of a wearable device (101). For example, the antenna (1455) may be composed of a single antenna and / or multiple segmented antennas. For example, the antenna (1455) may be composed of a part of a housing (1401) of the wearable device (101). For example, the antenna (1455) may be electrically connected to a communication circuit (1420) via a PCB (1451).

[0272] Although not illustrated, the wearable device (101) may include various other components in addition to the illustrated components. For example, the wearable device (101) may include a display. The display may be positioned on the outer surface of the housing (1401).

[0273] For example, a wearable device may require a method for detecting that the wearable device is worn by a user through the first sensor while being wirelessly connected to an external electronic device having a display using the communication circuit, and, based on the detection, deactivating the communication circuit and activating the second sensor used to obtain values ​​for the user's biometric information.

[0277] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to disable the communication circuitry by ceasing to provide power to the communication circuitry.

[0278] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to store the values ​​acquired via the second sensor in a buffer within the memory while the communication circuitry is deactivated. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to identify whether the number of the values ​​stored in the buffer reaches a reference number. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to keep the communication circuitry deactivated until the number reaches the reference number.

The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to transmit, to the external electronic device, the values ​​stored in the buffer, using the activated communication circuitry, based on the number reaching the reference number.

[0279] For example, the instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to transmit the values ​​to the external electronic device based on broadcasting the values ​​using the activated communication circuitry.

[0280] For example, the values ​​may be broadcast before a communication link between the wearable device and the external electronic device is established using the activated communication circuit.

The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to identify whether a state of charge (SoC) of the battery reaches a threshold SoC while the communication circuit is disabled. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to activate the communication circuit based on identifying the SoC of the battery that reached the threshold SoC before the count reaches the reference count.

The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to keep the communication circuit disabled based on obtaining the value below the threshold value through the second sensor. The instructions, when individually or collectively executed by the at least one processor, may cause the wearable device to activate the communication circuit based on obtaining the value above the threshold value through the second sensor. When executed individually or collectively by at least one processor, the wearable device may cause the wearable device to transmit, to the external electronic device, values ​​for the biometric information acquired through the second sensor during a time period between the time when the communication circuit is deactivated and the time when the communication circuit is activated, based on acquiring the value exceeding the reference value through the second sensor.
