[0029] Figure 1 illustrates an example of a wireless environment including electronic devices and wearable devices.

[0030] Referring to FIG. 1, the wearable device (110) may include at least one sensor. For example, the at least one sensor may be used to obtain biometric information of a user of the wearable device (110). For example, the at least one sensor may be used to detect whether the wearable device (110) is worn by a user. For example, the at least one sensor may include an acceleration sensor, an IMU (inertial measurement unit) sensor, a heart rate sensor, a body temperature sensor, a proximity sensor, and / or a biosensor. However, the present invention is not limited thereto.

[0031] For example, the wearable device (110) may include a communication circuit. For example, the wearable device (110) may transmit information about whether the wearable device (110) is worn by a user of the wearable device (110) to the electronic device (100) through the communication circuit. For example, the wearable device (110) may transmit sensing data acquired through at least one sensor to the electronic device (100) through the communication circuit.

[0032] For example, the wearable device (110) can be wirelessly connected to the electronic device (100) using a communication circuit. For example, the wearable device (110) can establish a communication link between the wearable device (110) and the electronic device (100) using the communication circuit. For example, the wearable device (110) can transmit sensing data to the electronic device (100) through the communication link between the wearable device (110) and the electronic device (100). For example, the wearable device (110) can transmit information related to the wearable device (110) to the electronic device (100) through the communication link between the wearable device (110) and the electronic device (100).

[0033] For example, the wearable device (110) may not be wirelessly connected to the electronic device (100). For example, a wearable device (110) that is not wirelessly connected to the electronic device (100) may include the wearable device (110) before being wirelessly connected to the electronic device (100). For example, the wearable device (110) may transmit information related to the wearable device (110) to the electronic device (100) via a communication circuit. For example, the wearable device (110) may advertise information related to the wearable device (110) via a communication circuit. For example, the wearable device (110) may broadcast information related to the wearable device (110) via a communication circuit.

[0034] For example, the wearable device (110) may include a wearable device (110) having a ring shape. For example, the wearable device (110) may include a housing that defines the appearance of the wearable device (110). For example, the housing of the wearable device (110) may include a first side facing a part of the user's body (e.g., a finger) and a second side opposite the first side. For example, the housing of the wearable device (110) may have a ring shape. An example of the structure of a wearable device (110) having a ring shape will be described and illustrated in more detail with reference to FIGS. 13A and 13B .

[0035] For example, the electronic device (100) may be one of various types of mobile devices, such as smartphones having various form factors (e.g., bar-type smartphones, foldable-type smartphones, or rollable-type smartphones), tablets, wearable devices, cellular phones, laptop computers, and / or other similar computing devices.

[0036] For example, the electronic device (100) may include a communication circuit. For example, the electronic device (100) may receive information related to the wearable device (110) from the wearable device (110) through the communication circuit. For example, the electronic device (100) may transmit a signal for controlling the wearable device (110) to the wearable device (110) through the communication circuit. For example, the electronic device (100) may transmit a signal causing activation of at least one sensor of the wearable device (110) to the wearable device (110) through the communication circuit.

[0037] Figure 2 illustrates an example of a user navigating his or her wearable device.

[0038] Referring to FIG. 2, state (201) may be represented as a state in which a user (200) searches for a wearable device (110) of the user (200). Searching for a wearable device (110) may be referred to as an operation for identifying the wearable device (110) of the user (200) among wearable devices (e.g., the wearable device (110) and the wearable device (210)). For example, state (201) may be described as a state in which the user (200) attempts to distinguish the wearable device (110) among the wearable devices (110) and the wearable devices (210).

[0039] For example, in state (201), the wearable device (110) may not include a display. As a non-limiting example, the wearable device (110) may include a display of a relatively small size. For example, the display of the wearable device (110) may be a hardware component for performing auxiliary functions of the wearable device (110).

[0040] For example, in state (201), the wearable device (110) may not include a speaker. As a non-limiting example, the wearable device (110) may include a speaker for relatively low volume audio. For example, the housing of the wearable device (110) may be substantially identical to the housing of the wearable device (210). For example, the exterior of the wearable device (110) may be substantially identical to the exterior of the wearable device (210). For example, the exterior of the wearable device (110) may be similar to the exterior of the wearable device (210). For example, the user (200) may have difficulty distinguishing between the wearable device (110) and the wearable device (210).

[0041] For example, in state (201), the wearable device (210) may have the same hardware components as the wearable device (110). For example, the wearable device (210) may not include a display and / or a speaker. For example, the wearable device (210) may have substantially the same appearance as the wearable device (110). For example, the user (200) may perceive the appearance of the wearable device (110) and the appearance of the wearable device (210) as being the same. For example, the user (200) may have difficulty distinguishing the wearable device (110) from the wearable device (210) because the appearances of the wearable device (110) and the wearable device (210) are the same. For example, as the number of wearable devices increases, the user (200) may have increasing difficulty in searching for (or identifying) the wearable devices (110). For example, a method for searching for (or identifying) the wearable devices (110) may be required.

[0042] For example, the user (200) may use a method of searching for the wearable device (110) of the user (200) among wearable devices (e.g., the wearable device (110) and the wearable device (210)) using the electronic device (100). For example, the electronic device (100) may search for the wearable device (110) of the user (200) among the wearable devices by performing at least some of the operations exemplified in FIG. 5. In other words, the electronic device (100) may execute operations to identify the wearable device (110) of the user (200) among the wearable devices.

[0043] For example, a wearable device to be described later (e.g., the wearable device (401) of FIG. 4) may include components (or hardware components) for providing such a method. The components will be described and exemplified in more detail with reference to FIG. 4.

For example, the display (330) may include light-emitting elements and circuits (e.g., transistors) that control the light-emitting elements to emit light. For example, each of the light-emitting elements may include an organic light emitting diode (OLED) or a micro LED. However, the present invention is not limited thereto. For example, the display (330) may include a liquid crystal display (LCD). For example, the display (330) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0052] A camera (340) may be available to acquire images and / or videos. The camera (340) may include one or more optical sensors (e.g., a charged coupled device (CCD) sensor, a complementary metal oxide semiconductor (CMOS) sensor) that generate electrical signals representing the color and / or brightness of light. A plurality of optical sensors included in the camera (340) may be arranged in the form of a two-dimensional array. The camera (340) may acquire electrical signals from each of the plurality of optical sensors substantially simultaneously, thereby generating an image corresponding to light reaching the optical sensors of the two-dimensional array and including a plurality of pixels arranged two-dimensionally. For example, the electronic device (301) may further include a flash light that is arranged to face the direction in which the camera (340) receives light and outputs light in the direction.

[0053] For example, at least one processor (300) may execute instructions stored in the memory (320) to identify a wearable device (e.g., the wearable device (401) of FIG. 4). For example, the instructions, when individually or collectively executed by the at least one processor (300), may cause the electronic device (301) to display identification information of the wearable device through the display (330).

For example, whether a visual object (770) that emits light in a light-emitting manner (710) is moving can be related to a movement (940) of the wearable device (401). For example, the electronic device (301) can identify that a visual object (770) that emits light in a light-emitting manner (710) is moving based on the motion information having the first value.

[0126] For example, the wearable device (701) may not have movement (940). For example, the movement information of the wearable device (701) may have the second value. For example, the electronic device (301) may identify that the visual object (780) corresponding to the wearable device (701) is not moving based on the movement information having the second value received from the wearable device (701).

[0127] Referring back to FIG. 9A, at operation 930, the electronic device (301) (e.g., at least one processor (300)) may display identification information via the display (330) based on identifying that a visual object (770) emitting light in a light-emitting manner (710) is moving. For example, the identification information may be associated with a visual object (770) within a preview image (740). For example, operation 930 may correspond to operation 519 of FIG. 5.

[0128] Referring to FIG. 9B, the electronic device (301) may display identification information (950) through the display (330) based on identifying that a visual object (770) that emits light in a light-emitting manner (710) is moving. For example, the electronic device (301) may display identification information (950) as an overlay on the visual object (770) through the display (330) based on identifying that a visual object (770) that emits light in a light-emitting manner (710) is moving. For example, the identification information (950) may correspond to the identification information (750) of FIG. 7A. For example, the size of the identification information (950) may be larger than the size of the identification information (750).

[0129] For example, the electronic device (301) may display a visual object (960) along with identification information (950) through the display (330) based on identifying that a visual object (770) that emits light in a light-emitting manner (710) is moving. For example, the visual object (960) may be used to highlight the visual object (770). For example, the visual object (960) is represented as a square with a dotted line, but this is merely an example. For example, the visual object (960) may be represented as a circle with a solid line, a check mark, etc., but is not limited thereto.

[0130] For example, the electronic device (301) may not display identification information (760) of the wearable device (701) based on identifying that the visual object (780) is not moving. For example, the electronic device (301) may stop displaying identification information (760) of the wearable device (701) based on identifying that the visual object (780) is not moving. For example, the electronic device (301) may refrain from displaying identification information (760) of the wearable device (701) based on identifying that the visual object (780) is not moving.

[0131] For example, a user of a wearable device (401) can cause identification information (950) and / or identification information (950) among identification information (760) to be displayed through a display (330) by causing movement (940) of the wearable device (401). For example, a user of a wearable device (401) can identify the wearable device (401) among a plurality of wearable devices by using movement (940) of the wearable device (401).

[0132] Figure 10 illustrates examples of operations in which a wearable device emits light using candidate light emission information received from an electronic device and light emission information received from another wearable device. In the following embodiments, 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.

[0133] Referring to FIG. 10, in operation 1010, the wearable device (701) may advertise (or broadcast) a third signal via a communication circuit. For example, the wearable device (701) may transmit the third signal to the wearable device (401) via the communication circuit. For example, the third signal may include light emission information of the wearable device (701). For example, the light emission information of the wearable device (701) may indicate the light emission method of the light emission element of the optical sensor of the wearable device (701).

[0134] For example, the wearable device (401) can receive a third signal through the communication circuit (410). For example, the wearable device (401) can identify the light emission information of the wearable device (701) based on receiving the third signal.

[0135] In operation 1020, the electronic device (301) (e.g., at least one processor (300)) may transmit a first signal to the wearable device via the communication circuit (310). For example, the electronic device (301) may advertise the first signal via the communication circuit (310). For example, the electronic device (301) may broadcast the first signal via the communication circuit (310).

[0136] For example, a wearable device (401) may receive a first signal via a communication circuit (410). For example, the first signal may include information that causes the wearable device receiving the first signal to emit light. For example, the information may include candidate light emission methods.

[0137] For example, the wearable device (401) may execute operations 1030, 1040, and / or 1050 based on the first signal. For example, the electronic device (301) may execute operations 1030, 1040, and / or 1050 in parallel based on the first signal.

[0138] In operation 1030, the wearable device (401) may determine, based on the first signal, light emission information corresponding to one of the candidate light emission methods within the first signal. For example, the wearable device (401) may select light emission information corresponding to one of the candidate light emission methods.

[0139] For example, the wearable device (401) may determine light emission information corresponding to one of the candidate light emission methods in the first signal using the light emission information of the wearable device (701) in the third signal. For example, the wearable device (401) may identify, based on the first signal, the remaining candidate light emission methods excluding the light emission information of the wearable device (701) in the third signal from among the candidate light emission methods in the first signal. For example, the wearable device (401) may determine (or select) light emission information corresponding to one of the remaining candidate light emission methods.

[0140] For example, by the wearable device (401) determining light emission information corresponding to one of the remaining candidate light emission methods, the light emission method (710) of the optical sensor (430) of the wearable device (401) and the light emission method (720) of the optical sensor (730) of the wearable device (701) can be distinguished. For example, by distinguishing the light emission method (710) and the light emission method (720), the accuracy with which the electronic device (301) identifies the wearable device (401) can be increased.

[0141] In operation 1040, the wearable device (401) may advertise a second signal including luminescence information and / or identification information (750) through the communication circuit (410) based on the first signal. For example, the wearable device (401) may broadcast the second signal through the communication circuit (410) based on the first signal. For example, the wearable device (401) may transmit the second signal to the electronic device (301) through the communication circuit (410) based on the first signal. For example, operation 1040 may correspond to operation 516 of FIG. 5 .

[0142] In operation 1050, the wearable device (401) may control the optical sensor (430) to emit light in a light-emitting manner (710) based on the first signal. For example, the wearable device (401) may cause the light-emitting element of the optical sensor (430) to emit light in a light-emitting manner (710). For example, operation 1050 may correspond to operation 517 of FIG. 5 .

For example, the electronic device (301) may execute operation 1070 based on identifying the visual object that emits light in the light-emitting manner using at least some of the images acquired through the camera (340). For example, the electronic device (301) may execute operation 1080 based on failing to identify the visual object that emits light in the light-emitting manner using at least some of the images acquired through the camera (340). For example, operation 1060 may correspond to operation 518 of FIG. 5.

[0144] In operation 1070, the electronic device (301) (e.g., at least one processor (300)) may display identification information (750) through the display (330) based on identifying a visual object that emits light in the light-emitting manner using at least some of the images. For example, operation 1070 may correspond to operation 519 of FIG. 5.

[0145] At operation 1080, the electronic device (301) (e.g., at least one processor (300)) may display a message (790) via the display (330) based on not identifying a visual object that emits light in the light-emitting manner using at least some of the images. For example, operation 1080 may correspond to operation 520 of FIG. 5 .

For example, the fourth signal may be represented as a signal for establishing a communication link (1130) between the electronic device (301) and the wearable device (1101).

[0148] In operation 1120, the electronic device (301) and the wearable device (1101) may establish a communication link (1130). As a non-limiting example, the communication link (1130) may be established based on an input to a user interface displayed on the display (330) of the electronic device (301) in response to an advertisement of the wearable device (1101). As a non-limiting example, the communication link (1130) may be established based on an input to a user interface displayed on the display (330) in response to a signal (or packet) transmitted (or broadcast) (or advertised) from the electronic device (301) in response to an advertisement of the electronic device (301).

[0149] In operation 1140, the electronic device (301) (e.g., at least one processor (300)) may execute operation 1140 based on an input for navigation of the wearable device (1101). For example, the input for navigation of the wearable device (1101) may be referred to as the input of operation 512 of FIG. 5.

[0150] For example, the electronic device (301) may transmit a fifth signal via a communication link (1130) using a communication circuit (310). For example, the fifth signal may include luminescence information. For example, luminescence information within the fifth signal may be distinguished from luminescence information within the second signal.

[0151] For example, the wearable device (1101) may receive a fifth signal via the communication link (1130). For example, the wearable device (1101) receiving the fifth signal via the communication link (1130) may be controlled by at least one processor of the wearable device (1101).

[0177] 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)).

[0178] According to one embodiment, commands or data may be transmitted or received between the electronic device (1201) and an external electronic device (1204) via a server (1208) connected to a second network (1299). Each of the external electronic devices (1202 or 1204) may be the same or a different type of device as the electronic device (1201). According to one embodiment, all or part of the operations executed in the electronic device (1201) may be executed in one or more of the external electronic devices (1202, 1204, or 1208). For example, when the electronic device (1201) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (1201) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (1201).

[0179] Figure 13a illustrates an exemplary wearable device.

[0180] Referring to FIG. 13A, a wearable device (1300) may include a housing (1310).

[0181] According to one embodiment, the wearable device (1300) can be worn by a user. For example, the wearable device (1300) can include the wearable device (401), the wearable device (701), and / or the wearable device (1101). The user can refer to a person who wears the wearable device (1300). The wearable device (1300) can be worn on a part (1370) of the user's body. For example, the wearable device (1300) can be worn on a part (1370) of the user's body. For example, the wearable device (1300) can be fastened to a part (1370) of the user's body. For example, the wearable device (1300) may be detachable from a part of the user's body (1370).

[0182] For example, the wearable device (1300) may be worn by a user and thus come into contact with a part of the user's body (1370). For example, the wearable device (1300) may be configured to obtain information related to the user through a part of the user's body (1370) by being worn by the user. For example, the wearable device (1300) may provide the user with information indicating the user's status based on the information obtained related to the user. For example, the wearable device (1300) may be configured to display information indicating the user's status through a display module (not shown) of the wearable device (1300) and / or an electronic device (e.g., an electronic device (301) of FIG. 3) connected to the wearable device (1300), thereby providing the user with information indicating the user's status. The wearable device (1300) may be referred to as the wearable device (401) of FIG. 4 in that it provides information related to a user wearing the wearable device (1300) to the user through an electronic device (301) connected to the wearable device (1300). However, the present invention is not limited thereto.

[0183] For example, the part of the user's body (1370) on which the wearable device (1300) is worn may be the user's finger. For example, the wearable device (1300) may be referred to as a finger-worn electronic device. For example, the housing (1310) of the wearable device (1300) may have a ring shape so that the wearable device (1300) may be worn on the user's finger. However, the present invention is not limited thereto. The wearable device (1300), which may be referred to as a wearable device, may have a shape corresponding to the part of the user's body (1370) so that it may be worn on the part of the user's body (1370).

[0184] According to one embodiment, the housing (1310) may include a first side (1310a) facing a first body part (1370) of a user while the wearable device (1300) is worn on the user's first body part (1370), and a second side (1310b) opposite the first side (1310a). The first body part (1370) may be one of the user's fingers. For example, at least a portion of the first side (1310a) may come into contact with the user's first body part (1370) when the wearable device (1300) is worn on the user. For example, the first side (1310a) may surround the user's first body part (1370) on which the wearable device (1300) is worn. For example, the first surface (1310a) may cover a first body part (1370) of a user on whom the wearable device (1300) is worn. For example, the first surface (1310a) may be configured to pressurize the first body part (1370) of the user when the wearable device (1300) is worn by the user, thereby fastening the wearable device (1300) to the first body part (1370).

[0185] For example, the second surface (1310b) may form an exterior of the electronic device (301) together with the first surface (1310a). For example, the second surface (1310b) may form a ring-shaped housing (1310) together with the first surface (1310a). For example, the second surface (1310b) may be a surface spaced apart from the first body part (1370) of the user when the electronic device (301) is worn on the user's first body part (1370). For example, while the electronic device (301) is worn on the user's first body part (1370), the first surface (1310a) may be a surface closest to the first body part (1370) of the user. The second surface (1310b) opposite the first surface (1310a) may be the surface furthest from the first body part (1370). For example, the first surface (1310a) may be referred to as the inner circumference surface of the housing (1310). The second surface (1310b) opposite the first surface (1310a) may be referred to as the outer circumference surface of the housing (1310).

[0186] Although the wearable device (1300) is described as being worn on the user's first body part (1370), it is not limited thereto. It should be noted that the first body part (1370) is intended to describe a part of the user's body (1370) on which the wearable device (1300) is worn, and does not limit the part of the user's body (1370) on which the wearable device (1300) is worn, or limit the arrangement relationship between the part of the body (1370) and the wearable device (1300). For example, the first body part (1370) may be one of the user's fingers, but is not limited thereto.

[0187] According to one embodiment, the housing (1310) may include a first frame (1311) defining a first surface (1310a), and a second frame (1312) defining a second surface (1310b) and coupled to the first frame (1311). For example, the first frame (1311) may be a portion of the housing (1310) that includes the first surface (1310a). For example, the first frame (1311) may come into contact with a part (1370) of a user's body when the wearable device (1300) is worn by the user. For example, the first surface (1310a) may form at least a portion of the exterior of the first frame (1311). A second surface (1310b) opposite the first surface (1310a) may form at least a portion of the exterior of the second frame (1312). For example, the first frame (1311) may be referred to as an inner wall of the housing (1310) at the point where it comes into contact with a part of the user's body (1370) while the wearable device (1300) is worn by the user. The first side (1310a) of the first frame (1311) may be referred to as an inner surface of the housing (1310) at the point where it at least partially surrounds a part of the user's body (1370) on which the wearable device (1300) is worn. For example, the second frame (1312) may be referred to as an outer wall of the housing (1310) at the point where it is coupled with the first frame (1311) to surround the first frame (1311). The second surface (1310b) of the second frame (1312) may be referred to as the outer surface of the housing (1310) in that it is the periphery that does not come into contact with a part of the body (1370) on which the wearable device (1300) is worn by the user while the wearable device (1300) is worn.For example, referring to FIG. 13B, the first frame (1311) may provide a medium for a path of light emitted from the light emitting portion (1351). The first frame (1311) may include, but is not limited to, at least one of silicon, epoxy, and acrylic.

[0188] For example, the second frame (1312) can surround the first frame (1311). For example, the second frame (1312) can support the first frame (1311). For example, the second frame (1312) can form the exterior of the housing (1310) together with the first frame (1311). For example, the second frame (1312) can be a portion of the housing (1310) that includes a second surface (1310b) opposite to the first surface (1310a). The second frame (1312) can include at least one of metal and titanium, but is not limited thereto. The housing (1310) of the wearable device (1300) can provide various user experiences to the user by including a first frame (1311) and a second frame (1312) made of different materials.

[0190] Referring to FIG. 13B, the wearable device (1300) may include electronic components within a housing (1310) to perform functions of the wearable device (1300). For example, the wearable device (1300) may include a processor (1301), a communication module (1302), a memory (1303), an antenna module (1304), and a power management module (1305). The power management module (1305) may be implemented as at least a part of a power management integrated circuit (PMIC).

[0191] According to one embodiment, a wearable device (1300) may include a battery (1330) for charging the wearable device (1300), and a printed circuit board (PCB) (1340) within a housing (1310) connected to the battery (1330). For example, a processor (1301), a communication module (1302), a memory (1303), and a power management module (1305) may be mounted on the printed circuit board (1340). The power management module (1305) may be configured to manage power supplied to the wearable device (1300).

[0194] The communication module (1302) can connect an external electronic device and a wearable device (1300). Through the communication module (1302), the processor (1301) can control at least some of the electronic components within the wearable device (1300) based on a user input inputted to the external electronic device, or can cause an event for executing a function of the external electronic device.

However, the present invention is not limited thereto.

[0195] According to one embodiment, the communication module (1302) may connect the wearable device (1300) to an external electronic device through near field communication. For example, the communication module (1302) may connect the wearable device (1300) to an external electronic device based on the external electronic device being within a specified distance range from the wearable device (1300). However, the present invention is not limited thereto. The communication module (1302) may establish a wireless communication network for communication with an external electronic device through WiFi, NFC, Zigbee, Bluetooth, RFID (Radio Frequency Identification), or a combination thereof. The communication module (1302) can transmit user input to the wearable device (1300) to the external electronic device or receive user input to the external electronic device from the external electronic device through a short-range wireless communication network between the wearable device (1300) and the external electronic device.
