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).

[0040] 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.

[0045] FIG. 2 is a cross-sectional view of a wearable electronic device (200) viewed from the front according to one embodiment of the present disclosure.

[0046] The wearable electronic device (200) illustrated in FIG. 2 may be at least partially similar to the electronic device (101) of FIG. 1, or may further include other embodiments of the electronic device. For example, the wearable electronic device (200) may include a smart ring that can be worn on a body part (e.g., a finger). However, the present invention is not limited thereto.

[0047] In describing the wearable electronic device (200) of the present disclosure, a ring-type (e.g., ring-shaped, ring-shaped) wearable electronic device worn on a user's finger is illustrated, but is not limited thereto. For example, the wearable electronic device (200) may include a bracelet-type wearable electronic device, an open-type electronic device with a portion open, or a curved or non-curved electronic device.

[0048] Referring to FIG. 2, a wearable electronic device (200) may include a housing (201) formed in an annular shape including an opening (2001) therein. In one embodiment, the housing (201) may include a first surface (e.g., an outer surface) that is exposed to an external environment when the wearable electronic device (200) is worn on a body part (e.g., a finger), and a second surface (e.g., an inner surface) that is located in an opposite direction to the first surface and at least partially contacts the skin of the finger when the wearable electronic device (200) is worn. For example, the inner surface of the housing (201) may refer to a surface (e.g., an inner side) that comes into contact with a finger when a user wears a ring-type wearable electronic device (200) on the finger. The outer surface of the housing (201) may refer to a surface (e.g., an outer side) that does not come into contact with a finger when a user wears a ring-type wearable electronic device (200) on the finger. For example, the outer circumference of the housing (201) may correspond to a large circular circumference, and the inner circumference may correspond to a small circular circumference.

[0049] In one embodiment, the opening (2001) may be formed to be sized to fit a user's finger through it.

[0050] In one embodiment, the wearable electronic device (200) may include a battery (189) and a substrate (240) disposed in an internal space of a housing (201). In one embodiment, the battery (189) and the substrate (240) may be disposed in opposite directions to each other, but the present invention is not limited thereto.

[0051] In one embodiment, the substrate (240) may be arranged in a manner that it is attached to the inner surface of the housing (201). For example, the substrate (240) may include a flexible printed circuit board (FPCB). For example, the substrate (240) may have a bendability to correspond to the curvature of the wearable electronic device (200) (e.g., the inner curvature corresponding to the opening (2001) of the housing (201). In some embodiments, the substrate (240) may include a substrate or a plurality of hard type substrates (PCBs, printed circuit boards) that include a hard type region having a width and length that are not interfered with the curvature of the housing (201).

[0052] In one embodiment, a plurality of electrical elements may be arranged on the substrate (240). For example, the plurality of electrical components may include at least one biometric sensor (e.g., a photoplethysmogram (PPG) sensor (231-1, 231-2, 231-3, 232-1, 232-2)) arranged to detect (or acquire) biometric information of the user through at least a portion (e.g., a first side, a second side) of the housing (201), an inertial sensor (220) (e.g., a three-axis sensor, a six-axis sensor, an acceleration sensor, a gyro sensor) for detecting movement of the wearable electronic device (200), a temperature sensor (211), a processor (120) (e.g., the processor (120) of FIG. 1), a memory (130) (e.g., the memory (130) of FIG. 1), a communication circuit (190) (e.g., the communication module (190) of FIG. 1), and / or a power management module (188) (e.g., the power management module (188) of FIG. 1).

[0053] In one embodiment, at least one biometric sensor (e.g., PPG sensor (231-1, 231-2, 231-3, 232-1, 232-2) (e.g., photoplethysmography sensor, photoplethysmography sensor)) can obtain biometric information of the user.

[0054] In one embodiment, the PPG sensors (231-1, 231-2, 231-3, 232-1, 232-2) can measure the pulse wave of the user located in a second direction along the second surface (e.g., inner surface) of the housing (201). For example, the PPG sensors can include light-emitting PPG sensors (231-1, 231-2, 231-3) that emit light and light-receiving PPG sensors (232-1, 232-2) that receive light.

[0055] In one embodiment, PPG sensors (231-1, 231-2, 231-3, 232-1, 232-2) (e.g., photoplethysmography sensor, photoplethysmography sensor) arranged based on the second surface (e.g., inner surface) of the housing (201) can detect blood flow (e.g., blood flow) using light. For example, when blood flows along a blood vessel, the amount of blood flow changes slightly, and the PPG sensor can measure the pulse wave (plethysmogram, PTG) of a user (e.g., a user wearing the wearable electronic device (200) on a finger) based on the amount of change in the amount of blood flow. The PPG sensor may include a light-emitting-PPG sensor (231-1, 231-2, 231-3) that emits light and a light-receiving-PPG sensor (232-1, 232-2) that receives light. For example, through the light-emitting PPG sensor (231-1, 231-2, 231-3), the emitted light may be at least partially reflected by an object, and at least a portion of the reflected light may be received through the light-receiving PPG sensor (232-1, 232-2). The processor (120) may measure the user's pulse wave based on the received light. According to one embodiment, the PPG sensors (231-1, 231-2, 231-3, 232-1, 232-2) may be controlled by the PPG control module (231). According to one embodiment, the PPG sensor is not limited to a specific method (e.g., reflective, transmissive), and is not limited to a blood flow measurement method based on a specific method. For example, the PPG sensor may be implemented in a reflective manner, a transmissive manner, and other methods.

[0056] In one embodiment, the temperature sensor (211) may measure the user's body temperature. However, the temperature sensor (211) may also measure the temperature of at least one of a plurality of electrical elements included in the wearable electronic device (200).

[0057] In one embodiment, when the occurrence of an event is detected, the processor (120) can emit light through the light-emitting PPG sensor (231-1, 231-2, 231-3) that emits light from the PPG sensor, thereby providing (e.g., outputting) visual notification information related to the event.

[0058] In one embodiment, the inertial sensor (220) may include at least one of a 3-axis sensor, a 6-axis sensor, an acceleration sensor, and / or a gyro sensor. In one embodiment, the inertial sensor (220) may determine a placement angle, a placement pose, and / or a placement position based on a set specific posture (e.g., an upright posture) of the wearable electronic device (200). The inertial sensor (220) may obtain coordinate information (e.g., gesture information, movement information) according to the posture, position, and / or movement of the wearable electronic device (200). In one embodiment, the processor (120) may detect various movements of the wearable electronic device (200) (e.g., finger movements of a user wearing the wearable electronic device (200)) based on the inertial sensor (220).

[0082] In various embodiments, the light emitting unit (310) may emit light (320, 347, and / or 365) when the occurrence of an event is detected under the control of a processor of the wearable electronic device (200) (e.g., processor (120) of FIG. 1).

Light (347 and / or 365) reflected (or collected) by the light guide member is scattered (349 and / or 367) by the light scattering member (e.g., the first light scattering member (343) and / or the second light scattering member (363)) and transmitted to the outside, thereby being recognized by the user's eyes (351), so that the user can intuitively check visual notification information related to the event.

[0083] In FIGS. 3A and 3B according to various embodiments, the wearable electronic device (200) is described as including a single light-emitting unit (e.g., light-emitting unit (310)), but is not limited thereto. For example, the wearable electronic device (200) may also include multiple light-emitting units. In this regard, various embodiments will be described in FIGS. 4A and 4B described below.

[0084] FIG. 4A is a diagram illustrating a wearable electronic device (200) including a plurality of light-emitting units (310, 415) according to one embodiment of the present disclosure.

[0085] According to one embodiment, FIG. 4a <410> is a cross-sectional view of a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) including a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)) viewed from the front. FIG. 4a according to one embodiment. <430> is a drawing of a wearable electronic device (200) including a plurality of light-emitting parts (310, 415) viewed from one side (e.g., direction ①).

[0086] Fig. 4a <410> and <430> Referring to FIG. 2 , the wearable electronic device (200) may include a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)). For example, the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)) may be disposed on the substrate (240) so as to face a specific direction (e.g., toward the opening (2001)). For example, the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)) may be disposed on the substrate (240) so as to be adjacent to each other (e.g., disposed parallel to each other) when the wearable electronic device (200) is viewed from the front. For another example, a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)) may be arranged on a substrate (240) so as to overlap each other when the wearable electronic device (200) is viewed from one side (e.g., direction ①).

[0087] In one embodiment, the plurality of light emitting units (e.g., the first light emitting unit (310) and the second light emitting unit (415)) may have different wavelengths.

[0088] In one embodiment, a plurality of light emitting units (e.g., first light emitting unit (310) and / or second light emitting unit (415)) may emit light (e.g., first light 320 and / or second light 420)) when an event is detected under the control of a processor (e.g., processor 120 of FIG. 1) of the wearable electronic device (200). For example, when an event is detected, the first light emitting unit (310) may emit first light (320) in a first wavelength range (e.g., green wavelength range) under the control of the processor (120). When an event is detected, the second light emitting unit (415) may emit second light (420) in a second wavelength range (e.g., red wavelength range) under the control of the processor (120).

[0089] In one embodiment, when light (e.g., first light (320) and / or second light (420)) is emitted through first light emitting unit (310) and second light emitting unit (415) having different wavelengths, a new wavelength range can be additionally implemented. For example, when first light (320) of a first wavelength range (e.g., green series wavelength range) is emitted through first light emitting unit (310) and second light (420) of a second wavelength range (e.g., red series wavelength range) is emitted through second light emitting unit (415), light of a new wavelength range, e.g., a third wavelength range (e.g., yellow series wavelength range), can be implemented.

[0090] In various embodiments, the first light emitting unit (310) and / or the second light emitting unit (415) may emit light (e.g., the first light (320) and / or the second light (420)) when the occurrence of an event is detected under the control of a processor (e.g., the processor (120) of FIG. 1) of the wearable electronic device (200). As the occurrence of the event is detected, the first light (320) emitted through the first light emitting unit (310) may be reflected (or collected) by a light guide member (e.g., the first light guide member (341) and / or the second light guide member (361)). In addition, as the occurrence of the event is detected, the second light (420) emitted through the second light emitting unit (415) may be reflected (or collected) by a light guide member (e.g., the first light guide member (341) and / or the second light guide member (361)). The light (320 and / or 420) reflected (or collected) by the light guide member is scattered by the light scattering member (e.g., the first light scattering member (343) and / or the second light scattering member (363)) and transmitted to the outside, thereby being recognized by the user's eyes (e.g., 351 in FIG. 3B), so that the user can intuitively check visual notification information related to the event.

[0091] FIG. 4a according to various embodiments <430> In , when the wearable electronic device (200) is viewed from one side (e.g., direction ①), the first light emitting unit (310) arranged on the back of the second light emitting unit (415) is shown as being visible, but since a plurality of light emitting units (e.g., the first light emitting unit (310) and the second light emitting unit (415)) are arranged to overlap each other, when the wearable electronic device (200) is viewed from one side (e.g., direction ①), the first light emitting unit (310) arranged on the back of the second light emitting unit (415) may not be visible.

[0092] Although the wearable electronic device (200) according to various embodiments is described as including two light-emitting units in FIG. 4A, this is not limited thereto. For example, the wearable electronic device (200) may include more than two light-emitting units.

[0093] FIG. 4b is a diagram illustrating a wearable electronic device (200) including a plurality of light-emitting units (310, 415) according to one embodiment of the present disclosure.

[0094] According to one embodiment, FIG. 4b <450> is a cross-sectional view of a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) including a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)) viewed from the front. FIG. 4b according to one embodiment. <470> is a drawing of a wearable electronic device (200) including a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)) viewed from one side.

[0095] Fig. 4b <450> and <470> Referring to FIG. 2 , the wearable electronic device (200) may include a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)). For example, the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)) may be disposed on the substrate (240) so as to face a specific direction (e.g., toward the opening (2001)). For example, the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)) may be disposed on the substrate (240) so as to overlap each other when the wearable electronic device (200) is viewed from the front.

[0096] In one embodiment, multiple light emitting units (e.g., first light emitting unit (310) and second light emitting unit (415)) may have the same wavelength.

[0097] In one embodiment, the wearable electronic device (200) includes a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (415)), such that at least one light-emitting unit can be used to measure (or obtain) a user's biometric information, and at least one other light-emitting unit can be used to output visual notification information related to an event.

[0098] For example, at least one of the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)) can measure (or obtain) the user's biometric information by emitting the first light (320) under the control of the processor (e.g., the processor (120) of FIG. 1) of the wearable electronic device (200). At least another of the plurality of light-emitting units (e.g., the first light-emitting unit (310) and the second light-emitting unit (415)), for example, the second light-emitting unit (415), can be electrically connected (e.g., coupled) to a second light guide member (361) and a second light-scattering member (363) that are arranged close to the second light-emitting unit (415) (e.g., arranged in a second lateral direction (e.g., in the direction ③) from the second light-emitting unit (415). Under the control of the processor of the wearable electronic device (200) (e.g., the processor (120) of FIG. 1), the second light (460) emitted through the second light emitting unit (415) can be reflected (or collected) by the second light guide member (361) that is electrically connected. The second light reflected (or collected) by the second light guide member (361) can be transmitted to the outside through the second light scattering member (363), thereby allowing the user to recognize visual notification information related to the event.

[0099] In one embodiment, when the wearable electronic device (200) includes a plurality of light-emitting units, for example, a first light-emitting unit (310) and a second light-emitting unit (415), a partition member (475) may be disposed between the first light-emitting unit (310) and the second light-emitting unit (415). By disposing the partition member (475) between the first light-emitting unit (310) and the second light-emitting unit (415), interference that may occur between the first light (320) emitted through the first light-emitting unit (310) and the second light (460) emitted through the second light-emitting unit (415) may be prevented.

[0100] As illustrated in FIGS. 4A and 4B according to various embodiments, the first light (320) emitted through the first light emitting unit (310) and / or the second light (460) emitted through the second light emitting unit (415) is transmitted in a first side direction (e.g., direction ②) and / or a second side direction (e.g., direction ③) by at least one light guide member (e.g., first light guide member (341) and / or second light guide member (361)) and at least one light scattering member (e.g., first light scattering member (343) and / or second light scattering member (363)) when the wearable electronic device (200) is viewed from one side (e.g., direction ①), so that the user can intuitively check visual notification information related to an event even when the user is wearing the wearable electronic device (200).

[0101] FIG. 5 is a cross-sectional view of a wearable electronic device (200) including a plurality of light-emitting units (310, 510) according to one embodiment of the present disclosure, viewed from the front.

[0102] Referring to FIG. 5, a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) may include a plurality of light-emitting units, for example, a first light-emitting unit (310) and a second light-emitting unit (510). The first light-emitting unit (310) and the second light-emitting unit (510) may include a laser diode.

[0103] In one embodiment, the first light emitting portion (310) and the second light emitting portion (510) may be disposed on a substrate (e.g., the substrate (240) of FIG. 2) so as to face a specific direction (e.g., toward the opening (2001)). For example, the first light emitting portion (310) and the second light emitting portion (510) may be disposed in the internal space of the housing (201) so as to face each other with the opening (2001) interposed therebetween when the wearable electronic device (200) is viewed from the front.

[0104] As illustrated in FIG. 5 according to one embodiment, a plurality of light-emitting units (e.g., a first light-emitting unit (310) and a second light-emitting unit (510)) are arranged in the internal space of the housing (201) so as to face each other when the wearable electronic device (200) is viewed from the front, and light (e.g., a first light (520) and a second light (530)) emitted through the plurality of light-emitting units (e.g., a first light (310) and a second light (510)) is transmitted to the outside by a light guide member (e.g., a first light guide member (341) and / or a second light guide member (361) of FIGS. 4A and 4B) and a light-scattering member (e.g., a first light-scattering member (343) and / or a second light-scattering member (363) of FIGS. 4A and 4B), thereby ensuring that there is no area where light is not irradiated. Accordingly, regardless of the direction in which the user wears the wearable electronic device (200), the user can check visual notification information related to the event through light (e.g., scattered light (349, 367) of FIG. 3b) transmitted to the outside of the wearable electronic device (200) (e.g., in the lateral direction (e.g., direction ② and / or direction ③ of FIGS. 3b and 4b)).

[0105] FIG. 6A is a cross-sectional view of a wearable electronic device (200) including a light-emitting unit (610) according to one embodiment of the present disclosure, viewed from the front. FIG. 6B is a view of a wearable electronic device (200) including a light-emitting unit (610) according to one embodiment of the present disclosure, viewed from one side.

[0106] Referring to FIGS. 6A and 6B, a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) may include a light-emitting unit (610) (e.g., the light-emitting-PPG sensors (231-1, 231-2, 231-3) of FIG. 2).

[0107] In one embodiment, the wearable electronic device (200) may include a substrate (240) disposed within an interior space of the housing (201). For example, the substrate (240) may have a bendability to correspond to a curvature of the wearable electronic device (200) (e.g., an internal curvature corresponding to an opening (2001) of the housing (201).

[0108] In one embodiment, a light emitting portion (610) may be disposed on the substrate (240). For example, the light emitting portion (610) may be disposed on the substrate (240) so as to face a specific direction (e.g., toward the opening (2001)).

[0109] In one embodiment, the light emitting portion (610) may include a laser diode.

[0110] In one embodiment, when the light emitting unit (610) includes a laser diode, light (640) emitted through the laser diode may have a straight line. Accordingly, the wearable electronic device (200) may include at least one light scattering member for scattering the light (640) having a straight line. The at least one light scattering member may be arranged in the internal space of the housing (201) so as to face the light emitting unit (610) with the opening (2001) interposed therebetween when the wearable electronic device (200) is viewed from the front.

[0111] In one embodiment, the at least one light-scattering member may include a first light-scattering member (620). In one embodiment, the first light-scattering member (620) may include a diffuse reflection member.

[0112] For example, the diffuse reflection member may include a grating structure. Light (640) entering the grating structure may be reflected (650, 660) at multiple angles. The multiple angles may be determined by the grating structure.

[0113] As another example, the diffuse reflection member may include a diffusion optics structure (or a mirror structure). Light (640) input to the diffusion optics structure may be reflected (650, 660) in multiple directions, regardless of a specific angle.

[0114] In one embodiment, light (640) emitted through the light emitting portion (610) may be reflected (650, 660) by the first light scattering member (620) and transmitted to the outside. As the light (640) is reflected (650) by the first light scattering member (620) and transmitted to the outside, it may be recognized through the user's eyes (351).

[0115] In one embodiment, the wearable electronic device (200) may include a light receiving portion (630) that receives light emitted through the light emitting portion (610) and reflected (660) by the first light scattering member (620).

[0116] In one embodiment, when the diffuse reflection member is formed of a grating structure, light (640) emitted through the light emitting portion (610) can be reflected (650, 660) at multiple angles by the grating structure, and the light receiving portion (630) can be placed in an internal space of the housing (201) corresponding to one of the multiple angles.

[0117] In one embodiment, a processor (e.g., processor (120) of FIG. 1) of a wearable electronic device (200) can determine whether the wearable electronic device (200) is worn on a user's finger based on light received through a light receiving unit (630). For example, the processor (120) can determine whether the wearable electronic device (200) is worn on a user's finger or whether a charging cradle is inserted through a circular opening (2001) at the center of the wearable electronic device (200), based on light received through the light receiving unit (630).

[0118] In one embodiment, when light emitted through the light emitting portion (610) and back-scattered by an object (e.g., a finger or a charging cradle) present in the annular opening (2001) at the center of the wearable electronic device (200) is received by the light receiving portion (630), the processor (120) can determine that the wearable electronic device (200) is worn on the user's finger.

[0119] In one embodiment, when the light (640) emitted through the light emitting unit (610) is not received by the light receiving unit (630), the processor (120) can determine that the wearable electronic device (200) is in a state where the charging cradle is inserted through the annular opening (2001) at the center of the wearable electronic device (200). For example, the charging cradle may be made of plastic, and thus, the light (640) emitted through the light emitting unit (610) may not be transmitted (or passed) to the charging cradle. In other words, when the charging cradle is inserted through the annular opening (2001) at the center of the wearable electronic device (200), back-scattering may not occur like the user's finger described above, and thus, no light may be received by the light receiving unit (630). Based on this, if the light (640) emitted through the light emitting unit (610) is not received by the light receiving unit (630), the processor (120) can determine that the wearable electronic device (200) is in a state where the charging cradle is inserted through the annular opening (2001) in the center of the wearable electronic device (200).

[0120] In FIGS. 6A and 6B according to various embodiments, the wearable electronic device (200) is described as including a single light-emitting unit (e.g., light-emitting unit (610)), but this is not limited thereto. For example, the wearable electronic device (200) may also include multiple light-emitting units. In this regard, various embodiments will be described in FIG. 7 described below.

[0121] FIG. 7 is a cross-sectional view of a wearable electronic device (200) including a plurality of light-emitting units (610, 710) according to one embodiment of the present disclosure, viewed from the front.

[0122] Referring to FIG. 7, a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) may include a plurality of light-emitting units, for example, a first light-emitting unit (610) and a second light-emitting unit (710) (e.g., light-emitting-PPG sensors (231-1, 231-2, 231-3) of FIG. 2). For example, the first light-emitting unit (610) and the second light-emitting unit (710) may be disposed on a substrate (e.g., the substrate (240) of FIG. 2) so as to face a specific direction (e.g., toward the opening (2001)).

[0123] In one embodiment, the first light emitting unit (610) and the second light emitting unit (710) may include laser diodes.

[0124] In one embodiment, the wearable electronic device (200) may include a first light-scattering member (620) for scattering first light emitted through the first light-emitting member (610) and a second light-scattering member (720) for scattering second light emitted through the second light-emitting member (710).

[0125] In one embodiment, the first light-scattering member (620) may be disposed in the internal space of the housing (201) so as to face the first light-emitting unit (610) with the opening (2001) interposed therebetween when the wearable electronic device (200) is viewed from the front. The second light-scattering member (720) may be disposed in the internal space of the housing (201) so as to face the second light-emitting unit (710) with the opening (2001) interposed therebetween when the wearable electronic device (200) is viewed from the front.

[0126] As illustrated in FIG. 7 according to one embodiment, by including a plurality of light-emitting units (e.g., a first light-emitting unit (610) and a second light-emitting unit (710)) and a plurality of light-scattering members (e.g., a first light-scattering member (620) and a second light-scattering member (720)) for scattering a plurality of lights emitted through the plurality of light-emitting units (e.g., the first light-scattering member (610) and the second light-scattering member (710)), the light reflected (650, 730) by the plurality of light-scattering members (e.g., the first light-scattering member (620) and the second light-scattering member (720)) is transmitted to the outside, thereby ensuring that there is no area where light is not irradiated. Accordingly, regardless of the direction in which the user wears the wearable electronic device (200), the user can check visual notification information related to an event through the reflected (650, 730) light.

[0127] FIG. 8 is a drawing for explaining a form in which a plurality of light-emitting units (811, 813, 815, 817) are arranged in a wearable electronic device (200) according to one embodiment of the present disclosure.

[0128] FIG. 8 according to one embodiment <810> Referring to , the housing (201) of a wearable electronic device (e.g., the wearable electronic device (200) of FIG. 2) may be formed in a circular shape.

[0129] In one embodiment, the wearable electronic device (200) may include a plurality of light-emitting units, for example, a first light-emitting unit (811), a second light-emitting unit (813), a third light-emitting unit (815), and / or a fourth light-emitting unit (817).

[0130] In one embodiment, the first light emitting portion (811), the second light emitting portion (813), the third light emitting portion (815), and / or the fourth light emitting portion (817) may be disposed on at least a portion of a substrate (e.g., the substrate (240) of FIG. 2) disposed in an interior space of the housing (201) along a shape of the housing (201), for example, an annular shape. For example, the first light emitting portion (811), the second light emitting portion (813), the third light emitting portion (815), and / or the fourth light emitting portion (817) may be disposed on at least a portion of the substrate (240) so as to correspond to each other, with the opening (2001) interposed therebetween, along the annular shape of the housing (201). For example, the first light emitting portion (811) and the third light emitting portion (815) may be disposed on at least a portion of the substrate (240) so as to correspond to each other, with the opening (2001) interposed therebetween. The second light emitting portion (813) and the fourth light emitting portion (817) can be arranged on at least a portion of the substrate (240) so as to correspond to each other with the opening (2001) therebetween.

[0131] It is not limited to this, and according to one embodiment, FIG. 8 <850> Referring to FIG. 8 , the first light-emitting portion (811), the second light-emitting portion (813), the third light-emitting portion (815), and / or the fourth light-emitting portion (817) may be disposed on at least a portion of the substrate (240) disposed in an internal space of the housing (201) corresponding to one area of ​​the wearable electronic device (200) (e.g., a lower area when the wearable electronic device (200) is viewed from the front).

[0132] According to the embodiments of FIGS. 2 to 8 described above, the processor of the wearable electronic device (200) (e.g., the processor (120) of FIG. 1) may emit light through at least one light-emitting unit when the occurrence of an event is detected.

[0133] In one embodiment, the event may include an event for emitting light through at least one light-emitting unit. For example, the event may include information related to measuring (or acquiring) biometric information of the wearable electronic device (200), information related to pairing with an external electronic device (e.g., the electronic device (102) or the electronic device (104) of FIG. 1), and / or status information of the wearable electronic device (200).

[0134] In one embodiment, information related to measuring (or acquiring) biometric information of a wearable electronic device (200) may include status information related to a biometric sensor (e.g., photoplethysmogram (PPG) sensors 231-1, 231-2, 231-3, 232-1, 232-2 of FIG. 2). For example, information related to measuring (or acquiring) biometric information of a wearable electronic device (200) may include information indicating a status of measuring (or acquiring) biometric information through a biometric sensor and / or biometric information acquired through the biometric sensor.

[0135] In one embodiment, the status information of the wearable electronic device (200) may include temperature information inside the wearable electronic device (200), external humidity information, remaining battery capacity information (e.g., battery (189) of FIG. 1), status information related to wearing the wearable electronic device (200), status information related to charging of the wearable electronic device (200), and / or status information related to the location of the wearable electronic device (200).

[0136] In one embodiment, the processor (120) can control the brightness, color, light emission state, and / or the number of light emission units that emit light through at least one light emitter in response to an event that has occurred. The processor (120) can cause light to be emitted through at least one light emitter based on the controlled brightness, color, light emission state, and number of light emission units that emit light.

[0137] For example, as described above with reference to FIG. 8, when the wearable electronic device (200) includes a plurality of light-emitting units, for example, a first light-emitting unit (811), a second light-emitting unit (813), a third light-emitting unit (815), and a fourth light-emitting unit (817), the processor (120) can control the light to be sequentially emitted through the first light-emitting unit (811), the second light-emitting unit (813), the third light-emitting unit (815), and the fourth light-emitting unit (817). As the light is sequentially emitted through the first light-emitting unit (811), the second light-emitting unit (813), the third light-emitting unit (815), and the fourth light-emitting unit (817), the light can be emitted in a form such as rotating in a specific direction (e.g., left or right).

[0138] For another example, the processor (120) can check the remaining capacity information of the battery (189) and cause at least some of the plurality of light-emitting units to emit light corresponding to the remaining capacity information of the battery (189).

[0139] For another example, as discussed above with reference to FIGS. 6A and 6B, the processor (120) may determine, based on light received through a light receiving unit (e.g., light receiving unit (630) of FIG. 6A), whether the wearable electronic device (200) is worn on the user's finger or inserted into a charging cradle through a circular opening (e.g., opening (2001) of FIG. 2) in the center of the wearable electronic device (200). The processor (120) may cause light corresponding to the state (e.g., the state in which the wearable electronic device (200) is worn on the user's finger or inserted into a charging cradle) to be emitted through at least one light emitting unit.

[0140] As another example, an external electronic device that is communicatively connected to a wearable electronic device (200) may execute a function for finding the wearable electronic device (200). In this case, the processor (120) of the wearable electronic device (200) may cause light to be emitted through at least one light-emitting unit based on a signal received from the communicatively connected external electronic device (200) (e.g., a signal related to execution of the function for finding the wearable electronic device (200).

[0141] In various embodiments, based on the detection of the occurrence of the aforementioned event, the processor (120) may emit light through at least one light emitting unit, and transmit the light to the outside by a light guide member (e.g., the first light guide member (341) and / or the second light guide member (361) of FIGS. 3A and 3B) and / or a light scattering member (e.g., the first light scattering member (343) and / or the second light scattering member (363) of FIGS. 3A and 3B) (or the first light scattering member (620) and / or the second light scattering member (720) of FIGS. 6 and 7), so that a user may recognize the light. Accordingly, the user may more intuitively confirm visual notification information related to the event through the light.

[0142] In one embodiment, the processor (120) may provide auditory notification information through an audio module (e.g., audio module (170) of FIG. 1) disposed within the wearable electronic device (200) and / or tactile notification information through a haptic module (e.g., haptic module (179) of FIG. 1)) along with visual notification information emitting light through at least one light-emitting unit.
