The communication module (190) may operate independently from the processor (120) (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 (190) may include a wireless communication module (192) (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 (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (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 LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0037] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0039] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to one surface (e.g., a bottom surface) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent to another surface (e.g., a top surface or a side surface) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0040] 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)).

[0041] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) 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.

For example, at least one processor (301) may identify the coupling of the first magnet (311) and the second magnet (321) and / or the coupling of the first ring (201) and the second ring (202) based on the magnetic force between the first magnet (311) and the second magnet (321) detected through the Hall sensor (303). The at least one processor (301) may be configured to connect the wearable device (200) to an external electronic device (101) through a communication circuit (302) based on identifying the coupling of the first ring (201) and the second ring (202).The at least one processor (301) may, based on identifying the coupling of the first ring (201) and the second ring (202), display visual information indicating that the first ring (201) and the second ring (202) are coupled on a display (e.g., a display module (160) of FIG. 1) of the external electronic device (101) connected to the wearable device (200) through the communication circuit (302), or provide audio information indicating that the first ring (201) and the second ring (202) are coupled through an audio module (e.g., an audio module (170) of FIG. 1) of the external electronic device (101). However, the present invention is not limited thereto.

[0056] According to one embodiment, the second ring (202) may be configured substantially identically or similarly to the first ring (201). For example, the second ring (202) may include a second processor (301b), a second communication circuit (302b), second Hall sensors (303c, 303d), a second power management circuit (305b), and a second memory (306b) mounted on the second flexible printed circuit board (32). The second power management circuit (305b) may be configured to manage power supplied to the second ring (202). The second ring (202) may include a second battery (304b) for supplying power to a plurality of electronic components mounted on the second flexible printed circuit board (32), a second charging interface (307b) for receiving power from an external power source for charging the second battery (304b), and a second antenna (308b).

[0057] The electronic components included in the first ring (201) and the second ring (202) of the wearable device (200) are not limited to the configuration described above. For example, the first ring (201) and the second ring (202) may each include various sensors, including a temperature sensor, a proximity sensor, a motion sensor, and a pressure sensor.

[0058] According to one embodiment, the first ring (201) may include a first housing (310) including a first magnet (311), and a first sensor (350) within the first housing (310). The second ring (202) may include a second housing (320) including a second magnet (321), and a second sensor (360) within the second housing (320).

[0059] For example, the first housing (310) may include a first side (310a) facing a part of the user's body (20) when the user wears the wearable device (200), and a second side (310b) opposite the first side (310a). The first ring (201) may include a plurality of electronic components disposed between the first side (310a) and the second side (310b). For example, the first sensor (350) may face the first side (310a) of the first housing (310) to detect information related to the user through the part of the user's body (20) on which the wearable device (200) is worn. For example, the first magnet (311) may be at least partially exposed to the outside of the first housing (310). The first magnet (311) may be attached to the second magnet (321) so as to be detachably coupled to the second magnet (321) of the second ring (202). For example, the first magnet (311) may be configured to detachably couple the first housing (310) to the second housing (320) through the magnetic force between the first magnet (311) and the second magnet (321).

[0060] For example, the second housing (320) may be configured substantially the same as or similar to the first housing (210). For example, the second housing (320) may include a third side (320a) facing a part of the user's body when the user wears the wearable device (200), and a fourth side (320b) opposite the third side (320a). The second ring (202) may include a plurality of electronic components disposed between the third side (320a) and the fourth side (320b). For example, the second sensor (360) may face the third side (320b) of the second housing (320) in order to detect information related to the user through the part (20) of the user's body on which the wearable device (200) is worn. For example, the second magnet (321) may be at least partially exposed to the outside of the second housing (320). The second magnet (321) may be attached to the first magnet (311) of the first ring (201) so as to be detachably coupled to the first magnet (311). For example, the second magnet (321) may have a polarity opposite to that of the first magnet (311), thereby allowing the second housing (320) to be detachably coupled to the first housing (310) via the first magnet (311).

[0061] According to one embodiment, the first sensor (350) may include a first light-emitting unit (351) configured to emit light toward a part of the body (20) of a user on whom the wearable device (200) is worn, and a first light-receiving unit (352) configured to receive at least a portion of light emitted from the first light-emitting unit (351) and reflected from the part of the body (20) of the user. For example, the first light-emitting unit (351) may include a plurality of light-emitting units (351a, 351b, 351c). The plurality of light-emitting units (351a, 351b, 351c) may face the first surface (310a) of the first housing (310) so as to emit light toward the part of the body (20) of the user on whom the wearable device (200) is worn, respectively. For example, the first light-receiving unit (352) may include a plurality of light-receiving units (352a, 352b, 352c). The plurality of light-receiving units (352a, 352b, 352c) may each face the first surface (310a) of the first housing (310) to receive at least a portion of the light emitted from the first light-emitting unit (351) and reflected by a part of the body (20) of the user wearing the wearable device (200). For example, the first sensor (350) may be configured to detect biometric information of the user by having the first light-receiving unit (352) receive at least a portion of the light emitted from the first light-emitting unit (351) and reflected by a part of the body (20) of the user.

[0062] According to one embodiment, the second sensor (360) may be configured substantially identically or similarly to the first sensor (350). For example, the second sensor (360) may include a second light-emitting portion (361) configured to emit light toward a portion (20) of a body of a user on whom the wearable device (200) is worn, and a second light-receiving portion (362) configured to receive at least a portion of light emitted from the second light-emitting portion (361) and reflected from the portion (20) of the body of the user. For example, the second light-emitting portion (361) may include a plurality of other light-emitting portions (361a, 361b 361c) facing the third side (320a) of the second housing (320). The second light receiving unit (362) may include a plurality of other light receiving units (362a, 362b, 362c) for receiving at least a portion of the light emitted from the second light emitting unit (361) and reflected by a part of the user's body (20).

[0063] According to one embodiment, the first sensor (350) and the second sensor (360) may each include at least one of an optical sensor module or a heart rate measurement (HRM) sensor module using photoplethysmography (PPG), but are not limited thereto. The first light-emitting unit (351) and the second light-emitting unit (361) may be referred to as a light emitting diode (LED), and the first light-receiving unit (352) and the second light-receiving unit (362) may be referred to as a photo diode, but are not limited thereto.

[0064] According to one embodiment, when only one of the first ring (201) and the second ring (202) is worn on a part of the user's body (20), the accuracy of information (e.g., biometric information) related to the user obtained through the first sensor (350) or the second sensor (360) may be reduced depending on the position of the first sensor (350) or the second sensor (360). The wearable device (200) may require a structure for increasing the accuracy of the information related to the user.

[0065] According to one embodiment, the second sensor (360) may be configured to receive at least a portion of light emitted from the first light emitting portion (351) and passing through a part (20) of the user's body through a second housing (320) coupled to the first housing (310) via a second light receiving portion (362). For example, the second housing (320) may be detachably coupled to the first housing (310) through a magnetic force between the first magnet (311) and the second magnet (321). The second ring (202) may be coupled to the first ring (201) by the second housing (320) being detachably coupled to the first housing (310). The second sensor (360) within the second ring (202) may be placed above the first ring (201) while the first ring (201) and the second ring (202) are combined.

[0066] For example, the first housing (310) may include a first hole (315) for passing a part of the user's body (20). The second housing (320) may further include a second hole (325) configured to pass the part of the user's body (20) by being connected to the first hole (315) while the first ring (201) is coupled with the second ring (202). While the first housing (310) and the second housing (320) are coupled by a magnetic force between the first magnet (311) and the second magnet (321), at least a portion of the light emitted from the first light-emitting portion (351) of the first sensor (350) may be received by the second light-receiving portion (362) of the second sensor (360) across the first hole (315) and the second hole (325). For example, while the first ring (201) and the second ring (202) are coupled, the wearable device (200) can be worn on a part of the user's body (20) by having the first hole (315) and the second hole (325) penetrate the part of the user's body (20). At least a portion of the light emitted from the first light-emitting portion (351) can pass through the part of the user's body (20) that penetrates the first hole (315) and the second hole (325) and be received by the second light-receiving portion (362). For example, the first sensor (350) can emit light toward the first surface (310a) of the first housing (310) by using the first light-emitting portion (351). At least a portion of the light emitted from the first light emitting portion (351) toward the first surface (310a) may pass through a part of the user's body (20) and be transmitted to the second light receiving portion (362) through the third surface (320a) of the second housing (320). For example, by attaching the second magnet (321) to the first magnet (311), the position of the second sensor (360) relative to the first sensor (350) may be limited so that the second light receiving portion (362) receives at least a portion of the light from the first sensor (350).The second sensor (360) for the first sensor (350) is positioned to receive at least a portion of the light emitted from the first light-emitting portion (351) of the first sensor (350) by the magnetic force between the first magnet (311) and the second magnet (321) and passing through a part of the user's body (20), thereby increasing the accuracy of the information related to the user provided by the wearable device (200).

[0067] According to one embodiment, the first sensor (350) may be configured to receive, through the first light-receiving portion (352), at least a portion of light emitted from the second light-emitting portion (361) and passing through a part (20) of the user's body, through the second housing (320) coupled to the first housing (310). For example, while the first housing (310) and the second housing (320) are coupled by the magnetic force between the first magnet (311) and the second magnet (321), at least a portion of light emitted from the second light-emitting portion (361) of the second sensor (360) may be received by the first light-receiving portion (352) of the first sensor (350) across the second hole (325) and the first hole (315). For example, while the first ring (201) and the second ring (202) are coupled, the wearable device (200) can be worn on a part of the user's body (20) by having the first hole (315) and the second hole (325) penetrate the part of the user's body (20). At least a portion of the light emitted from the second light-emitting portion (361) can pass through the part of the user's body (20) that penetrates the second hole (325) and the first hole (315) and be received by the first light-receiving portion (352). For example, the second sensor (360) can emit light toward the third surface (320a) of the second housing (320) by using the second light-emitting portion (361). At least a portion of the light emitted from the second light emitting portion (361) toward the third surface (320a) can pass through a part of the user's body (20) and be transmitted to the first light receiving portion (352) through the first surface (310a) of the first housing (310). For example, by attaching the second magnet (321) to the first magnet (311), the position of the first sensor (350) relative to the second sensor (360) can be limited so that the first light receiving portion (352) receives at least a portion of the light from the second sensor (360).The first sensor (350) is positioned so as to receive at least a portion of the light emitted from the second light emitting portion (361) of the second sensor (360) by the magnetic force between the first magnet (311) and the second magnet (321) and passing through a part of the user's body (20), thereby increasing the accuracy of the information related to the user provided by the wearable device (200).

[0068] In one embodiment, the first housing (310) may include a first side (310c) on which a first magnet (311) is disposed. The second housing (320) may include a second side (320c) on which a second magnet (321) is disposed and configured to be attached to the first side (310c) by a magnetic force between the first magnet (311) and the second magnet (321). For example, the first side (310c) may extend from the first side (210a) of the first housing (210) to the second side (210b). For example, the first magnet (311) may be attached to the first side (310c). For example, the first magnet (311) may be at least partially exposed to the outside of the first housing (310) through the first side (310c). For example, the second side (320c) may extend from the third side (320a) of the second housing (210) to the fourth side (320b). For example, the second magnet (321) may be attached to the second side (320c). For example, the second side (320c) may be detachably attached to the first side (310c) by the magnetic force between the first magnet (311) and the second magnet (321). For example, the second side (320c) may be attached to the first side (310c) by the first magnet (311) and the second magnet (321), thereby connecting the second hole (325) to the first hole (315). The second side (320c) may be configured to be attached to the first side (310c) so that light emitted from the first light-emitting portion (351) is received by the second light-receiving portion (362) across the first hole (315) and the second hole (325). The first side (310c) may be configured to be attached to the second side (320c) so that light emitted from the second light-emitting portion (361) is received by the first light-receiving portion (352) across the second hole (325) and the first hole (315).

[0069] According to one embodiment, the first housing (310) may include a third magnet (312) disposed on the first side (310c) and facing the first magnet (311). The second housing (320) may include a fourth magnet (322) disposed on the second side (320c) and facing the second magnet (321). The position of the second sensor (360) with respect to the first sensor (350) may be configured to be fixed by a magnetic force between the first magnet (311) and the second magnet (321) and a magnetic force between the third magnet (312) and the fourth magnet (322).

[0070] For example, the first magnet (311) can be attached to the second magnet (321) by an attractive force with the second magnet (321). The third magnet (312) can be attached to the fourth magnet (322) by an attractive force with the fourth magnet (322). The first magnet (311) can repel the fourth magnet (322) by a repulsive force. The second magnet (321) can repel the third magnet (321) by a repulsive force. The wearable device (200) can fix the position of the second ring (201) with respect to the first ring (201) by the first magnet (311) being attached to the second magnet (321) and the third magnet (312) being attached to the fourth magnet (322). The second ring (201) can be fastened to the first ring (201) so that at least a portion of the light emitted from the first light emitting unit (351) in the first sensor (350) passes through a part (20) of the body of the user wearing the wearable device (200) and is received by the second light receiving unit (362) in the second sensor (360). The first ring (201) may be fastened to the second ring (202) so that at least a portion of the light emitted from the second light emitting portion (361) in the second sensor (360) passes through a part (20) of the body of the user wearing the wearable device (200) and is received by the first light receiving portion (352) in the first sensor (350). The wearable device (200) may include magnets (311, 312, 321, 322) configured to fix the position of the second sensor (360) with respect to the first sensor (350), thereby increasing the accuracy of the information related to the user provided by the sensor modules (350, 360).

[0071] In one embodiment, the second sensor (360) may face the first sensor (350) while the first ring (201) is coupled with the second ring (202). For example, the second sensor (360) may be positioned symmetrically with respect to the first sensor (350) while the first ring (201) and the second ring (202) are coupled by the magnetic force between the first magnet (311) and the second magnet (321). For example, the second sensor (360) may be positioned adjacent to a portion of the first face (310a) that the first sensor (350) faces while the first ring (201) is coupled with the second ring (202). The first sensor (350) may be positioned adjacent to a portion of the third face (320a) that the second sensor (360) faces. The second sensor (360) is configured to face the first sensor (350) while the first ring (201) is coupled with the second ring (202), thereby increasing the accuracy of the user-related information provided by the wearable device (200). For example, the angle between the axis connecting the center of the first hole (315) and the first sensor (350) and the axis connecting the center of the second hole (325) and the second sensor (360) may be positioned within a range of approximately 90 degrees to 180 degrees. However, the present invention is not limited thereto.

[0072] According to one embodiment, the wearable device (200) may provide information related to electronic components of the first ring (201) and / or electronic components of the second ring (202) to an external electronic device (101) connected to the wearable device (200) via a communication circuit (302). At least one processor (301) may control at least some of the electronic components of the first ring (201) and / or at least some of the electronic components of the second ring (202) based on a user input received by the external electronic device (101). At least one processor (301) may be configured to bypass power supply to at least one of the first sensor (350) or the second sensor (360) via a power management circuit (305) based on a user input received by the external electronic device (101). For example, at least one processor (301) may be configured to bypass power supply to at least one of the first light-emitting unit (351) and the second light-emitting unit (361) and to bypass power supply to at least one of the second light-receiving unit (362) and the second light-receiving unit (362) through the power management circuit (305) based on a user input received by the external electronic device (101). The wearable device (200) is configured to control power supply to electronic components within the wearable device (200) based on the coupling of the first ring (201) and the second ring (202), thereby reducing unnecessary power consumption and providing various user experiences to the user. Controlling electronic components within the wearable device (200) based on the user input will be described later with reference to FIGS. 5A and 5B.

[0073] According to the above-described embodiment, the wearable device (200) can provide various user experiences to the user by including a first ring (201) and a second ring (202) detachably coupled to the first ring (201). The wearable device (200) can increase the accuracy of the user-related information provided by the sensor modules (350, 360) by including magnets (311, 312, 321, 322) configured to fix the position of the second sensor (360) of the second ring (202) with respect to the first sensor (350) of the first ring (201) while the first ring (201) and the second ring (202) are coupled.

[0074] Figure 4 illustrates an exemplary wearable device.

[0075] Referring to FIG. 4, a wearable device (200) may include a first housing (310) including a first magnet (311), and a first ring (201) including a first sensor (350) within the first housing (310). The wearable device (200) may include a second housing including a second magnet (321), and a second ring (202) including a second sensor (360) within the second housing (320), and being detachably coupled to the first ring (201) by a magnetic force between the first magnet (311) and the second magnet (321). The first sensor (350) may include a first light-emitting unit (e.g., the first light-emitting unit (351) of FIG. 3A) configured to emit light toward a part of the body of a user wearing the wearable device (200) (e.g., the part of the body (20) of FIG. 2), and a first light-receiving unit (e.g., the first light-receiving unit (352) of FIG. 3A). The second sensor (360) may include a second light-receiving unit (e.g., the second light-receiving unit (362) of FIG. 3B) configured to receive at least a portion of light emitted from the first light-emitting unit (351) and passing through the part of the body (20) of the user through the second housing (320) coupled to the first housing (310) and the second light-emitting unit (e.g., the second light-receiving unit (361) of FIG. 3B).

[0076] Hereinafter, redundant descriptions of the configurations described in FIGS. 3a to 3d are omitted.

[0077] Referring to FIG. 4, unlike FIGS. 3A to 3D, while the first ring (201) and the second ring (202) are coupled by the first magnet (311) and the second magnet (321), the second sensor (360) may not face the first sensor (350). For example, at least a portion of the light emitted from the first light emitting portion (351) of the first sensor (350) may be reflected by a part of the user's body (20) and then received by the second light receiving portion (362) of the second sensor (360). The second sensor (360) may be configured to detect the user's biometric information through at least a portion of the light emitted from the first light emitting portion (351). For example, at least a portion of the light emitted from the second light emitting portion (361) of the second sensor (360) may be reflected by a part of the user's body (20) and then received by the first light receiving portion (352) of the first sensor (350). The first sensor (350) may be configured to detect the user's biometric information through at least a portion of the light emitted from the second light emitting portion (361). For example, the first housing (310) may include a first hole (315), and the second housing (320) may include a second hole (325) connected to the first hole (315) while the first ring (201) and the second ring (202) are coupled. The angle between the axis connecting the center of the first hole (315) and the first sensor (350) and the axis connecting the center of the second hole (325) and the second sensor (360) may be positioned within a range of approximately 0 degrees to 90 degrees or less. However, it is not limited thereto.

[0078] According to the above-described embodiment, the wearable device (200) is configured to fix the position of the second sensor (360) of the second ring (202) relative to the first sensor (350) of the first ring (201) while the first ring (201) and the second ring (202) are coupled, thereby increasing the accuracy of the user-related information provided by the sensor modules (350, 360).

[0079] FIG. 5a and FIG. 5b are flow charts illustrating the operation of a processor of an exemplary wearable device.

[0080] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0081] The operations of FIG. 5a and FIG. 5b may be performed by at least one processor (301) of FIG. 3a and FIG. 3b.

[0082] Referring to FIGS. 5A and 5B , in operation 501, at least one processor (301) may be configured to identify the engagement of a first ring (e.g., the first ring (201) of FIG. 3A ) and a second ring (e.g., the second ring (202) of FIG. 3B ) by a Hall sensor (e.g., the Hall sensor (303) of FIG. 3A ). For example, the at least one processor (301) may identify the engagement of the first ring (201) and the second ring (202) by a change in magnetic force between the first magnet (e.g., the first magnet (311) of FIG. 3A ) and the second magnet (e.g., the second magnet (321) of FIG. 3B ) detected by the Hall sensor (303).

[0083] Referring to FIG. 5A, in operation 503, at least one processor (301) may be configured to identify whether the first ring (201) and the second ring (202) are coupled. For example, the at least one processor (301) may identify the coupling of the first ring (201) and the second ring (202) based on identifying the attractive force between the first magnet (311) and the second magnet (321) detected through the Hall sensor (303). For example, the at least one processor (301) may identify that the first ring (201) and the second ring (202) are separated based on identifying that no magnetic force is detected through the Hall sensor (303).

[0084] In operation 505, at least one processor (301) may be configured to provide information related to the first ring (201) and the second ring (202) to an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (200) via a communication circuit (e.g., the communication circuit (302) of FIG. 3A) based on identifying that the first ring (201) and the second ring (202) are coupled. For example, a first processor of a first ring (201) (e.g., a first processor (301a) of FIG. 3A) may provide information related to the first ring (201) through a first communication circuit (e.g., a first communication circuit (302a) of FIG. 3A) or provide information related to a second ring (202) obtained through a first antenna (e.g., a first antenna (308a) of FIG. 3A) through an external electronic device (101). For example, a second processor of a second ring (202) (e.g., a second processor (301b) of FIG. 3b) may provide information related to the first ring (201) through a second communication circuit (e.g., a second communication circuit (302b) of FIG. 3b) or may provide information related to the second ring (202) obtained through a second antenna (e.g., a second antenna (308b) of FIG. 3b) through an external electronic device (101).

[0085] In operation 507, at least one processor (301) may be configured to identify a user input received by the external electronic device (101) connected to the wearable device (200) via the communication circuit (302). For example, at least one processor (301) may be configured to identify a user input received by the external electronic device (101) via the communication circuit (302), a processor of the external electronic device (101) (e.g., the processor (120) of FIG. 1), and a communication circuit of the external electronic device (101) (e.g., the communication circuit (190) of FIG. 1).

[0086] In operation 509, at least one processor (301) may be configured to control power supply to at least some of the electronic components within a first housing (e.g., the first housing (310) of FIG. 3A) including a first sensor (e.g., the first sensor (350) of FIG. 3A) and at least some of the electronic components within a second housing (e.g., the second housing (320) of FIG. 3B) including a second sensor (e.g., the second sensor (360) of FIG. 3B) based on identifying a user input, via a power management circuit (e.g., the power management circuit (305) of FIGS. 3A and 3B). For example, the user input inputted to the external electronic device (101) may be an input for bypassing power supply to at least some of the electronic components of the first ring (201) and / or at least some of the electronic components of the second ring (202). For example, the first processor (301a) may be configured to control the first power management circuit (e.g., the first power management circuit (305a) of FIG. 3a) to bypass power supply to at least one of the first light-emitting unit (e.g., the first light-emitting unit (351) of FIG. 3a) and the first light-receiving unit (e.g., the first light-receiving unit (352) of FIG. 3a) of the first sensor (350) based on identifying a user input. For example, the second processor (301b) may be configured to control the second power management circuit (e.g., the second power management circuit (305b) of FIG. 3b) to bypass power supply to at least one of the second light-emitting unit (e.g., the second light-emitting unit (361) of FIG. 3b) and the second light-receiving unit (e.g., the second light-receiving unit (362) of FIG. 3b) of the second sensor (360) based on identifying a user input. For example, at least one processor (301) can turn off power to the first ring (201) or turn off power to the second ring (202) via the power management circuit (305).However, without limitation thereto, at least one processor (301) may be configured to bypass power supply to at least some of the electronic components illustrated in FIGS. 3A and 3B based on user input received from an external electronic device (101).

[0087] In operation 511, at least one processor (301) may be configured to bypass providing at least some of the information related to the first ring (201) and the second ring (202) through the external electronic device (101) based on identifying that the first ring (201) and the second ring (202) have been separated. For example, at least one processor (301) may be configured to bypass providing at least some of the information related to the first ring (201) and the second ring (202) based on identifying that a magnetic force detected by the Hall sensor (303) is not identified.

[0088] Referring to FIG. 5B, in operation 513, at least one processor (301) may be configured to identify an intensity (s1) of a first signal representing information related to the user received by the light-receiving unit (e.g., the first light-receiving unit (352) of FIG. 3A) through the first sensor (350) based on identifying the coupling of the first ring (201) and the second ring (202). For example, the at least one processor (301) may identify an intensity of a signal emitted from the first light-emitting unit (351) and reflected by a part of the user's body (e.g., the part of the body (20) of FIG. 2) and transmitted to the first light-receiving unit (352). For example, the at least one processor (301) may identify an intensity of a signal emitted from the second light-emitting unit (361) and transmitted to the first light-receiving unit (352) through a part of the user's body (20).

[0089] In operation 515, at least one processor (301) may be configured to identify, based on identifying the coupling of the first ring (201) and the second ring (202), an intensity (s2) of a second signal representing information related to the user received by another light-receiving unit (e.g., the second light-receiving unit (362) of FIG. 3B) through the second sensor (360). For example, the at least one processor (301) may identify an intensity of a signal emitted from the second light-emitting unit (361), reflected by a part of the user's body (20), and transmitted to the second light-receiving unit (362). For example, the at least one processor (301) may identify an intensity of a signal emitted from the first light-emitting unit (351), passed through a part of the user's body (20), and transmitted to the second light-receiving unit (362).

[0090] In operation 517, at least one processor (301) may provide information indicating the intensity (s1) of the first signal and the intensity (s2) of the second signal to the external electronic device (101) via the communication circuit (302). For example, at least one processor (301) may provide information related to the intensity (s1) of the first signal and the intensity (s2) of the second signal via the communication circuit (302) and the processor (120) of the external electronic device (101), thereby providing the user with various user experiences using the first sensor (350) or the second sensor (360).

[0091] According to the above-described embodiment, at least one processor (301) of the wearable device (200) is configured to control electronic components of the first ring (201) and the second ring (202) through an external electronic device (101), thereby providing various user experiences to the user.

[0092] Figures 6a and 6b illustrate exemplary wearable devices.

[0093] Referring to FIGS. 6A and 6B, a wearable device (200) may include a first housing (310) including a first magnet (311), and a first ring (201) including a first sensor (350) within the first housing (310). The wearable device (200) may include a second housing including a second magnet (321), and a second ring (202) including a second sensor (360) within the second housing (320), and being detachably coupled to the first ring (201) by a magnetic force between the first magnet (311) and the second magnet (321). The first sensor (350) may include a first light-emitting unit (e.g., the first light-emitting unit (351) of FIG. 3A) configured to emit light toward a part of the body of a user wearing the wearable device (200) (e.g., the part of the body (20) of FIG. 2), and a first light-receiving unit (e.g., the first light-receiving unit (352) of FIG. 3A). The second sensor (360) may include a second light-receiving unit (e.g., the second light-receiving unit (362) of FIG. 3B) configured to receive at least a portion of light emitted from the first light-emitting unit (351) and passing through the part of the body (20) of the user through the second housing (320) coupled to the first housing (310) and the second light-emitting unit (e.g., the second light-receiving unit (361) of FIG. 3B). According to one embodiment, the first housing (310) may further include a first hole (315) for passing a part of the user's body (20). The second housing (320) may further include a second hole (325) configured to pass a part of the user's body (20) by being connected to the first hole (315) while the first ring (201) is coupled to the second ring (202).

[0094] Referring to FIG. 6A, the wearable device (200) may include a third ring (203) positioned between the first ring (201) and the second ring (202) while the first ring (201) and the second ring (202) are coupled. The first ring (201) and the second ring (202) may each be rotatable with respect to the third ring (203). For example, the third ring (203) may include a material having magnetism. For example, the first ring (201) may be attached to one side of the third ring (203) by a magnetic force between the first magnet (311) and the third ring (203). For example, the second ring (202) may be attached to the other surface opposite to the one surface of the third ring (203) by the magnetic force between the second magnet (321) and the third ring (203). For example, the third ring (203) may be referred to as a metal ring, but is not limited thereto.

[0095] For example, the first ring (201) and the second ring (202) may be rotatable while attached to the third ring (203). The first ring (201) and / or the second ring (202) may be rotatable in a first rotational direction (601) and a second rotational direction (602) opposite to the first rotational direction, respectively, with respect to the third ring (203). For example, a Hall sensor (e.g., Hall sensor (303) of FIG. 3A) within the wearable device (200) may detect a change in magnetic force between the first magnet (311) and the third ring (203) and / or a change in magnetic force between the second magnet (321) and the third ring (203). At least one processor (e.g., at least one processor (301) of FIG. 3A) within the wearable device (200) may be configured to identify rotation of the first ring (201) and / or rotation of the second ring (202) with respect to the third ring (203) based on a change in magnetic force detected from the Hall sensor (303). The at least one processor (301) may be configured to control an external electronic device (101) connected to the wearable device (200) based on identifying the rotation of the first ring (201) and / or the rotation of the second ring (202) with respect to the third ring (203). For example, at least one processor (301) may control the external electronic device (101) to adjust the volume of a speaker (e.g., an audio module (170) of FIG. 1) within the external electronic device (101) through a processor (e.g., a processor (120) of FIG. 1) within the external electronic device (101) based on identifying the rotation of the first ring (201) and / or the rotation of the second ring (202).For example, at least one processor (301) may control the external electronic device (101) to change visual information displayed by a display (e.g., a display module (160) of FIG. 1) of the external electronic device (101) based on identifying the rotation of the first ring (201) and / or the rotation of the second ring (202) through the processor (120) within the external electronic device (101). For example, at least one processor (301) may control the external electronic device (101) to cause a camera (e.g., a camera module (180) of FIG. 1) of the external electronic device (101) to zoom in or out based on identifying the rotation of the first ring (201) and / or the rotation of the second ring (202). However, the present invention is not limited thereto.

[0096] Although the third ring (203) is described as being positioned between the first ring (201) and the second ring (202) and rotatably connecting the first ring (201) and the second ring (202) with respect to the third ring (203), it is not limited thereto. The third ring (203) may include a plurality of electronic components as described with reference to FIGS. 3A and 3B. The third ring (203) may include at least one processor (301), thereby providing information related to whether the third ring (203) is coupled with the first ring (201) and / or the second ring (202) through an external electronic device (101) connected to the third ring (203). However, without being limited thereto, the wearable device (200) may be configured such that three or more ring-shaped devices are detachably coupled to each other to generate an event for executing a function of the external electronic device (101) or such that each of the ring-shaped devices shares the function of a plurality of electronic components included in the ring-shaped devices.

[0097] Referring to FIG. 6B, the first magnet (311) may include a first set of magnets (610) spaced apart from each other at a specified interval along the first hole (315). The second ring (202) may be configured to be rotatable relative to the first ring (201) through a magnetic force between the first set of magnets (610) and the second magnet (321) while being coupled to the first ring (201).

[0098] For example, the first set of magnets (610) may include first magnets (611, 612, 613, 614, 615, 616, 617, 618) spaced at a specified interval. The second magnet (321) may be positioned on the first magnets (611, 612, 613, 614, 615, 616, 617, 618) respectively by causing the second ring (202) to rotate in a first rotational direction (601) relative to the first ring (201) and in a second rotational direction (602) opposite to the first rotational direction (601). Since the polarities of each of the first magnets (611, 612, 613, 614, 615, 616, 617, 618) and the second magnet (321) are different from each other, the second ring (202) can maintain a coupling with the first ring (201) through the magnetic force between each of the first magnets (611, 612, 613, 614, 615, 616, 617, 618) and the second magnet (321) while rotating with respect to the first ring (201). For example, the second magnet (321) may include a second set of magnets (620) spaced apart at a specified interval. The magnets (620) of the second set can reduce the detachment of the second ring (202) from the first ring (201) while the second ring (202) rotates in a first rotational direction (601) and a second rotational direction (602) opposite to the first rotational direction, through the magnetic force with the magnets (610) of the first set.

[0099] For example, the second magnet (321) may include a second set of magnets (620) spaced apart from each other and having a different polarity from the first set of magnets (610) so as to be coupled to at least a portion of the first set of magnets (610). For example, the second set of magnets (620) may include second magnets (621, 622, 623) spaced apart at a specified interval on the second side (320c). Each of the second magnets (621, 622, 623) is positioned at a position corresponding to at least some of the first magnets (611, 612, 613, 614, 615, 616, 617, 618), so that the second side (320c) can be attached to the first side (310c) through magnetic force with at least some of the first magnets (611, 612, 613, 614, 615, 616, 617, 618).

[0100] According to one embodiment, the Hall sensor (303) may be configured to detect a change in magnetic force between each of the first set of magnets (610) and the second magnet (321). For example, the Hall sensor (303) may be disposed within the second ring (202). The Hall sensor (303) may be attached to a second side (320c) of the second ring (202) on which the second magnet (321) is disposed. The second side (320c) may include metal so as to be attachable to the first side (310c) via the first set of magnets (610) on the first side (310c). However, the present invention is not limited thereto. Unlike as illustrated, the Hall sensor (303) may be disposed within the first ring (201). The Hall sensor (303) may be attached to a first side (310c) of the first ring (201) on which a first set of magnets (610) are arranged. The first side (310c) may include a metal so as to be attachable to the second side (320c) via a second magnet (321) on the second side (320c). At least one processor (301) of the wearable device (200) may be configured to identify a rotation and / or a rotational direction (e.g., a first rotational direction (601) and a second rotational direction (602)) of the second ring (202) with respect to the first ring (201) through a change in magnetic force between the first set of magnets (610) and the second magnet (321) detected by the Hall sensor (303). The at least one processor (301) may be configured to control the external electronic device (101) through a processor (120) within the external electronic device (101) based on identifying the rotation and / or rotational direction of the second ring (202) with respect to the first ring (201).For example, at least one processor (301) may control the external electronic device (101) through the processor (120) of the external electronic device (101) to adjust the volume of a speaker within the external electronic device (101), change visual information displayed by a display of the external electronic device (101), or cause a camera of the external electronic device (101) to zoom in or out, based on identifying the rotation of the second ring (202) with respect to the first ring (201). However, the present invention is not limited thereto.

[0101] According to the above-described embodiment, the wearable device (200) may be configured to control an external electronic device (101) connected to the wearable device (200) through rotation of the second ring (202) relative to the first ring (201), by including a second ring (202) configured to be rotatably coupled to the first ring (201).

[0102] Figure 7 is a flowchart illustrating the operation of a processor of an exemplary wearable device.

[0103] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0104] The operation of FIG. 7 may be performed by at least one processor (301) of FIG. 3A. Operation 701 may correspond to operation 501 of FIGS. 5A and 5B.

[0105] In operation 703, at least one processor (301) may be configured to identify a rotation of the second ring (202) relative to the first ring (201) through a magnetic force between a first set of magnets (e.g., the first set of magnets (610) of FIG. 6B) and a second magnet (e.g., the second magnet (321) of FIG. 3B) based on identifying an engagement of the first ring (e.g., the first ring (201) of FIG. 3A) and the second ring (e.g., the second ring (202) of FIG. 3B). For example, the at least one processor (301) may be configured to identify a rotation of the second ring (202) relative to the first ring (201) through a change in a magnetic force detected by a Hall sensor (e.g., the Hall sensor (303) of FIG. 3A). For example, the Hall sensor (303) may include a plurality of Hall sensors (e.g., the first Hall sensors (303a, 303b) of FIG. 3A, and the second Hall sensors (303c, 303d) of FIG. 3B) included in the first ring (201) and / or the second ring (202). Since the first ring (201) or the second ring (202) each includes a plurality of Hall sensors, at least one processor (301) may be configured to acquire 2-axis data via the plurality of Hall sensors. The at least one processor (301) may be configured to identify, via at least a portion of the data acquired by the plurality of Hall sensors, the rotation of the second ring (202) with respect to the first ring (201) and / or the rotation of the first ring (201) with respect to the second ring (202). For example, although not illustrated in FIGS. 3A and 3B, the wearable device (200) may further include a magnetic sensor. At least one processor (301) may be configured to acquire 3-axis data via the magnetic sensor.The at least one processor (301) may be configured to identify, through at least a portion of the data acquired via the magnetic sensor, rotation of the second ring (202) with respect to the first ring (201) and / or rotation of the first ring (201) with respect to the second ring (202).

[0106] In operation 705, at least one processor (301) may be configured to control the external electronic device (e.g., the electronic device (101) of FIG. 1) through a communication circuit (e.g., the communication circuit (302) of FIG. 3A) based on identifying the rotation of the second ring (202) relative to the first ring (201). For example, the at least one processor (301) may control the external electronic device (101) to adjust the volume of the external electronic device (101) based on identifying the rotation of the second ring (202) relative to the first ring (201). However, the present invention is not limited thereto.

[0107] According to the above-described embodiment, at least one processor (301) of the wearable device (200) is configured to control an external electronic device (101) based on identifying the rotation of the second ring (202) with respect to the first ring (201), thereby providing a variety of user experiences to the user.

[0108] Figure 8 illustrates an exemplary wearable device.

[0109] Referring to FIG. 8, a wearable device (200) may include a first housing (310) including a first magnet (311), and a first ring (201) including a first sensor (350) within the first housing (310). The wearable device (200) may include a second housing including a second magnet (321), and a second ring (202) including a second sensor (360) within the second housing (320), and being detachably coupled to the first ring (201) by a magnetic force between the first magnet (311) and the second magnet (321). The first sensor (350) may include a first light-emitting unit (e.g., the first light-emitting unit (351) of FIG. 3A) configured to emit light toward a part of the body of a user wearing the wearable device (200) (e.g., the part of the body (20) of FIG. 2), and a first light-receiving unit (e.g., the first light-receiving unit (352) of FIG. 3A). The second sensor (360) may include a second light-receiving unit (e.g., the second light-receiving unit (362) of FIG. 3B) configured to receive at least a portion of light emitted from the first light-emitting unit (351) and passing through the part of the body (20) of the user through the second housing (320) coupled to the first housing (310) and the second light-emitting unit (e.g., the second light-receiving unit (361) of FIG. 3B).

[0110] According to one embodiment, the second housing (320) may include at least one conductive pin (810). The first housing (310) may include at least one connector hole (820) that is electrically connected to at least one conductive pin (810) while the first ring (201) is coupled to the second ring (202). For example, the first magnet (311) may be disposed on a first side (310c) of the first housing (310). The second magnet (321) may be disposed on a second side (320c) of the second housing (320). The at least one conductive pin (810) may protrude from the second side (320c) on which the second magnet (321) is disposed. At least one connector hole (820) may be formed on the first side (310c) where the first magnet (311) is arranged. For example, the at least one conductive pin (810) may include a plurality of conductive pins (811, 812, 813, 814). The at least one connector hole (820) may include a plurality of connector holes (821, 822, 823, 824). The plurality of conductive pins (811, 812, 813, 814) may be inserted into the plurality of connector holes (821, 822, 823, 824) while the first ring (201) is coupled with the second ring (202), thereby electrically connecting the first ring (201) and the second ring (202).

[0111] According to one embodiment, the first ring (201) may include a first memory (e.g., the first memory (306a) of FIG. 3a) within a first housing (310). The second ring (202) may include a second memory (e.g., the second memory (306b) of FIG. 3b) within a second housing (320). The first ring (201) may be configured to transmit data from the first memory (306a) to the second memory (306b) or receive data from the second memory (306b) to the first memory (306a) via the at least one conductive pin (810) connected to the at least one connector hole (820). For example, a first processor (e.g., a first processor (301a) of FIG. 3A) of a first ring (201) may be configured to transmit at least some of the data stored in a first memory (306a) to a second memory (306b) based on a user input received from an external electronic device (e.g., an electronic device (101) of FIG. 1). For example, a second processor (e.g., a second processor (301b) of FIG. 3B) of a second ring (202) may be configured to transmit at least some of the data stored in a second memory (306b) to the first memory (306a) based on a user input received from an external electronic device (101).

[0112] According to one embodiment, the first ring (201) may include a first battery (e.g., the first battery (304a) of FIG. 3A) for supplying power. The second ring (202) may include a second battery (304b) for supplying power to the second ring (202). The first ring (201) may be configured to supply power from the first battery (304a) to the second battery (304b) or to receive power from the second battery (304b) to the first battery (304a) through the at least one conductive pin (810) connected to the at least one connector hole (820). For example, the first processor (301a) of the first ring (201) may be configured to supply power from the first battery (304a) to the second battery (304b) through the first power management circuit (305a) based on a user input received from the external electronic device (101). For example, the second processor (301b) of the second ring (202) may be configured to supply power from the second battery (304b) to the first battery (304a) through the second power management circuit (305b) based on a user input received from the external electronic device (101).

[0113] For example, unlike as illustrated in FIGS. 3A and 3B , the second ring (202) may have a substantially different configuration from the first ring (201). The second ring (202) may, for example, not include at least one processor (301). The size and / or capacity of the second battery (304b) disposed inside the second housing (320) of the second ring (202) may be larger than the size and / or capacity of the first battery (304a) in the first ring (201). The second ring (202) may be configured to charge the first ring (201) through the second battery (304b) having a larger capacity than the first battery (304a) by being connected to the first ring (201). For example, the size and / or capacity of the second memory (306b) disposed inside the second housing (320) of the second ring (202) may be larger than the size and / or capacity of the first memory (306a) in the first ring (201). The second ring (202) may be connected to the first ring (201) and may store data from the first ring (201) through the second memory (306b) having a larger capacity than the first memory (306a).
