For example, if the electronic device (101) includes a main processor (121) and a secondary processor (123), the secondary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a specified function. The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0033] The auxiliary processor (123) may control at least a part of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. According to one embodiment, the display module (160) 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.

[0039] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0040] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0041] The interface (177) may support one or more designated protocols that may be used to directly or wirelessly connect the electronic device (101) with an external electronic device (e.g., the electronic device (102)).

According to one embodiment, the haptic module (179) can include, for example, a motor, a piezoelectric element, or an electrical stimulation device.

[0044] The camera module (180) can capture still images and videos. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0045] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented as, for example, at least a part of a power management integrated circuit (PMIC).

[0046] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0047] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. 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).

[0048] 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. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) may support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0049] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). According to one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). According to one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. According to some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0050] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) 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 a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0051] 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)).

[0052] 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 by 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 (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0053] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may display information about a wearable device using a display. For example, the electronic device may display information about a wearable device using the display based on identifying that the wearable device is located on the display of the electronic device. When the electronic device is connected to multiple wearable devices, it may be necessary to identify the wearable device located on the display of the electronic device. In the following specification, technical features for identifying a wearable device (or an identifier (ID) of the wearable device) located on the display of the electronic device will be described.

[0054] Figure 2 illustrates examples of electronic devices and wearable devices.

[0055] Referring to FIG. 2, the electronic device (101) may correspond to the electronic device (101) of FIG. 1. The electronic device (101) may include a display (312). For example, the electronic device (101) may display information about the wearable device (200) through the display (312).

[0056] According to one embodiment, the electronic device (101) can establish a connection with the wearable device (200). The wearable device (200) can be connected to the electronic device (101) using various radio access technologies (RATs) (e.g., Bluetooth communication, wireless local area network (WLAN)). For example, the wearable device (200) can control the electronic device (101) or be controlled by the electronic device (101). As an example, the wearable device (200) can receive a request for information about a user from the electronic device (101). The wearable device (200) can transmit information about the user to the electronic device (101) based on the request received from the electronic device (101).

[0057] According to one embodiment, the electronic device (101) may display information about the wearable device (200) based on identifying that the wearable device (200) is positioned on the display (312) of the electronic device (101). For example, the wearable device (200) may include a display that is too small to display information, or may not include a display. Accordingly, the electronic device (101) may display a user interface (201) for displaying information about the wearable device (200) based on identifying that the wearable device (200) is positioned on the display (312) of the electronic device (101). For example, information about the wearable device (200) may include at least one of information about a user identified through the wearable device (200), remaining battery power of the wearable device (200), information about an account of the wearable device (200), and / or information about a function that can be performed on the wearable device (200). The electronic device (101) may, based on identifying that the wearable device (200) is located on the display (312) of the electronic device (101), display at least one of information about a user identified through the wearable device (200), remaining battery power of the wearable device (200), information about an account of the wearable device (200), and / or information about a function that can be performed on the wearable device (200) through the user interface (201).

[0058] For example, the user interface (201) may include a visual object (202) indicating that the wearable device (200) is in contact with the display (312). For example, the visual object (202) may indicate an area where the wearable device (200) is in contact with the display (312). For example, the visual object (202) may indicate that information about the wearable device (200) is being displayed through the display (312). For example, the visual object (202) may be displayed to provide various visual effects indicating that the wearable device (200) is in contact with the display (312). As an example, the visual object (202) may indicate that information about the wearable device (200) is being loaded. As an example, the visual object (202) may include an object indicating that the wearable device (200) is being scanned.

[0059] According to one embodiment, the wearable device (200) may be configured to be worn on a part of the user's body (e.g., a finger). For example, the wearable device (200) may be worn on a part of the user's body. For example, the wearable device (200) may be fastened to a part of the user's body. For example, the wearable device (200) may be detachable from a part of the user's body. For example, the wearable device (200) may have a shape corresponding to a part of the user's body in order to be worn on a part of the user's body.

[0060] For example, the wearable device (200) may be worn by the user and thus come into contact with a part of the user's body. For example, the wearable device (200) may be configured to obtain information about the user through a part of the user's body by being worn by the user. For example, the wearable device (200) may provide information about the user through the wearable device (200) and / or an electronic device (101) connected to the wearable device (200). However, the present invention is not limited thereto.

[0061] According to one embodiment, the wearable device (200) may include a housing (210) including a first side (211) facing a part of a user's body (e.g., a finger) and a second side (212) opposite the first side (211). For example, the wearable device (200) may include a ring-shaped housing (210). As an example, the wearable device (200) may be configured in a ring shape. In FIG. 2, an example in which the shape of the wearable device (200) is configured in a ring shape is illustrated, but the present invention is not limited thereto. The shape and form of the wearable device (200) are not limited to the embodiment, and may include various shapes (e.g., square, oval, etc.) that can be worn on a part of a user's body (e.g., a finger, a wrist, an earlobe).

[0062] According to one embodiment, at least a portion of the first surface (211) may come into contact with a part of the user's body when the wearable device (200) is worn by the user. For example, the first surface (211) may surround a part of the user's body on which the wearable device (200) is worn. For example, the first surface (211) may cover a part of the user's body on which the wearable device (200) is worn. For example, the first surface (211) may be configured to pressurize a part of the user's body when the wearable device (200) is worn by the user, thereby fastening the wearable device (200) to the part of the body. For example, the first surface (211) may be deformable by a part of the user's body. For example, the wearable device (200) can provide information about the user through the first surface (211) based on haptic technology. For example, the smart ring device (200) can provide information indicating that the user's heart rate is higher than a specified heart rate by outputting vibration. For example, the smart ring device (200) can provide notifications about the user's health status by outputting vibration. For example, the smart ring device (200) can provide notifications about a schedule set by the user by outputting vibration.

[0063] For example, the second surface (212) may form an outer appearance of the wearable device (200) together with the first surface (211).

According to one embodiment, one of the main processor and the secondary processor may be activated depending on the state and / or operation of the wearable device (200). For example, the secondary processor may be activated when the battery of the wearable device (200) is low.

[0098] For example, the PPG sensor (327) may include a transmissive PPG sensor and / or a reflective PPG sensor.

[0099] For example, the PPG sensor (327) can output light toward the user's skin via one of an LED (e.g., green, red, or IR (infrared)), a laser, and a VCSEL (vertical cavity surface emitting laser). The PPG sensor (327) can identify light reflected and / or transmitted from the user's skin via at least one of a PD and / or a CMOS (complementary metal oxide semiconductor) camera. The PPG sensor (327) can store the identified value via an analog to digital converter (ADC) in the memory (240) (or buffer) based on the reflected and / or transmitted light.

[0100] For example, a transmissive PPG sensor can identify light passing through a blood vessel through a PD positioned opposite the LED. The transmissive PPG sensor can identify the user's blood flow based on the intensity of the light passing through the blood vessel. For example, a reflective PPG sensor can output light toward the user's skin through an LED. The reflective PPG sensor can identify light that is reflected by the blood vessel and at least partially received through a PD positioned on substantially the same surface as the LED. The reflective PPG sensor can identify the user's blood flow based on the intensity of the light reflected by the blood vessel. For example, multiple light sources can be used, such as LEDs.

For example, the wearable device (200) may identify external light based on a sensing frequency (or a specified cycle) by using the light-receiving circuit. For example, the wearable device (200) may identify external light 60 times per second (i.e., 60 Hz) by using the light-receiving circuit. For example, the wearable device (200) may acquire 2^60 bits of data per second. As the sensing frequency increases, the wearable device (200) may acquire more data in the same amount of time.

[0182] For example, a window (1191) may be disposed on one side of a display panel (1195). The window (1191) may be disposed to protect the display panel (1195) and transmit light emitted from the display panel (1195) to the outside. For example, the adhesive layers (1192, 1194) may include an optically clear adhesive (OCA). For example, a polarizing layer (1193) may be disposed to transmit light vibrating along a designated linear trajectory. For example, a protective layer (1196) may be disposed to protect the display (312) by absorbing external impact. The protective layer (1196) may include a light-blocking layer (e.g., an embo layer) and a cushion layer. A metal layer (1197) may be disposed to prevent interference by external electrical signals.

[0183] According to one embodiment, a magnetic field can be emitted using a coil included in the wearable device (200). The electronic device (101) can identify the magnetic field emitted from the wearable device (200) using an electromagnetic induction circuit (315). Based on the identified magnetic field, the electronic device (101) can identify that the wearable device (200) is positioned on the display (312). The electronic device (101) can identify an area on the display (312) where the wearable device (200) is positioned.

[0184] According to one embodiment, the wearable device (200) may be positioned on the display (312) of the electronic device (101). The wearable device (200) may include a component capable of inducing an electrical change (or a change in capacitance) of the touchscreen panel (316). Based on the positioning of the wearable device (200) on the display (312) of the electronic device (101), an electrical change of the touchscreen panel (316) may occur. The electronic device (101) may identify that the wearable device (200) is positioned on the display (312) based on the electrical change of the touchscreen panel (316). The electronic device (101) may identify an area on the display (312) where the wearable device (200) is positioned.

[0185] FIG. 11b illustrates an example of an operation of an electronic device to identify that a wearable device is positioned on a display.

[0186] Referring to FIG. 11b, in the above-described embodiment, an example was described in which the electronic device (101) outputs a light-emitting signal of a first pattern through the display (312) and the wearable device (200) identifies a light-receiving signal of a second pattern. However, in FIG. 11b, the wearable device (200) can output a light-emitting signal of a first pattern and the electronic device (101) can identify a light-receiving signal of a second pattern.

[0187] According to one embodiment, the electronic device (101) may transmit a signal to the wearable device (200) that causes the wearable device (200) to output a light-emitting signal of a first pattern based on identifying a touch input of a specified shape. The wearable device (200) may output the light-emitting signal of the first pattern using the light-emitting circuit (327-1) based on the received signal. The electronic device (101) may identify that the wearable device (200) is positioned on the display (312) using at least one of a camera, a proximity sensor, and / or an optical fingerprint sensor based on the light-emitting signal.

[0188] For example, the wearable device (200) may be positioned in an area (1110) corresponding to a location where at least one of a camera, a proximity sensor, and / or an optical fingerprint sensor is disposed. The area (1110) may include an area in which a light-emitting signal output from the wearable device (200) is identified using at least one of the camera, the proximity sensor, and / or the optical fingerprint sensor. The electronic device (101) may identify a first pattern of light-emitting signals output from the wearable device (200) using at least one of the camera, the proximity sensor, and / or the optical fingerprint sensor. The electronic device (101) may identify that the wearable device (200) is positioned in the area (1110) on the display (312) based on identifying that a second pattern of the light-receiving signal corresponds to the first pattern.

[0189] FIG. 12A illustrates an example of the operation of a wearable device for identifying a second pattern of a light-receiving signal.

[0190] FIG. 12b illustrates an example of the operation of a wearable device for identifying a second pattern of a light-receiving signal.

[0191] FIG. 12c illustrates an example of the operation of a wearable device for identifying a second pattern of a light-receiving signal.

[0192] Referring to FIG. 12A, the wearable device (200) can obtain a light-receiving signal (1201) using one or more light-receiving circuits (327-2) based on a light-emitting signal output through the display (312) of the electronic device (101). The light-receiving signal (1201) can be referred to as a PPG analog signal. The light-receiving signal (1201) identified by the wearable device (200) can include noise caused by a change in brightness of the display (312) and / or external light (e.g., sunlight). Therefore, the wearable device (200) can identify the second pattern based on performing a sampling operation and / or a quantization operation.

[0193] According to one embodiment, the wearable device (200) can convert an optical signal into an electrical signal using one or more light-receiving circuits (327-2). By converting the optical signal into an electrical signal, the wearable device (200) can identify the light-receiving signal (1201).

[0194] The wearable device (200) can convert the light reception signal (1201) into a digital signal (1202) using an analog to digital converter (ADC). For example, the wearable device (200) can convert the light reception signal (1201) into a digital signal (1202) based on a sampling operation. The wearable device (200) can sample the light reception signal (1201) based on a specified sampling period. Since the digital signal (1202) identified through the sampling operation also includes noise, a quantization operation can be performed for noise filtering.

[0195] The wearable device (200) may change the digital signal (1202) into a quantized digital signal (1203) based on a quantization operation. For example, the wearable device (200) may perform the quantization operation based on integrating two or more sensor values ​​for noise filtering. For example, the wearable device (200) may determine an integrated value as an average value (or a median value) of values ​​over a certain time period. The wearable device (200) may set values ​​over a certain time period as an integrated value. As the number of integrated values ​​increases, noise in the light-receiving signal (1201) may be removed. According to an embodiment, the wearable device (200) may identify the identified integrated values ​​as a second pattern (or bit information regarding the second pattern).

[0196] The wearable device (200) can identify a second pattern based on the quantized digital signal (1203). For example, in order to increase reliability, the wearable device (200) can identify a value in a section where the quantized digital signal (1203) is greater than or equal to a reference value (1205) as a first value (e.g., '1'), and can identify a value in a section where the quantized digital signal (1203) is less than the reference value (1205) as a second value (e.g., '0'). The wearable device (200) can identify a second pattern (e.g., '101010') based on the quantized digital signal (1203) and the reference value (1205). According to an embodiment, the operations of the wearable device (200) described above can be preset through signal exchange between the electronic device (101) and the wearable device (200). At least one of the wearable device (200) and / or the electronic device (101) can identify whether the second pattern identified in the wearable device (200) corresponds to the first pattern.

[0197] According to one embodiment, accuracy may be improved as the amount of sampled data increases and the sensing time increases. However, as the amount of sampled data increases and the sensing time increases, noise may increase or usability may decrease. The electronic device (101) and / or the wearable device (200) may determine an optimal data size. The electronic device (101) may set the output of the display (312) based on the optimal data size. The wearable device (200) may set the sensing time based on the optimal data size.

[0198] Referring to FIG. 12b, the wearable device (200) may not be aware of the range of the light-emitting signal output from the display (312). For example, if the sensitivity of one or more light-receiving circuits (327-2) is set high, the light may be saturated and the light-receiving signal may not be discernible.

[0199] For example, the wearable device (200) can identify the second pattern based on the quantized digital signal (1211). The wearable device (200) can identify a value in a section where the quantized digital signal (1211) is greater than or equal to a reference value (1213) as a first value (e.g., '1'), and can identify a value in a section where the quantized digital signal (1211) is less than the reference value (1213) as a second value (e.g., '0'). If the reference value (1213) is set too low, the second pattern may be identified only by the first value.

[0200] According to one embodiment, the electronic device (101) may first transmit the maximum and minimum values ​​of the light emission signal to the wearable device (200). In an OLED-based display, the electronic device (101) may transmit the maximum value of the light emission signal to the wearable device (200) based on displaying white. In an OLED-based display, the electronic device (101) may transmit the minimum value of the light emission signal to the wearable device (200) based on displaying black.

[0201] The wearable device (200) can identify the maximum and minimum values ​​of the quantized digital signal (1212) based on the maximum and minimum values ​​of the luminescence signal. The wearable device (200) can identify the reference value (1214) based on the maximum and minimum values ​​of the quantized digital signal (1212). For example, the wearable device (200) can identify the maximum value of the quantized digital signal (1212) in a time interval (1215). The wearable device (200) can identify the minimum value of the quantized digital signal (1212) in a interval (1216). The wearable device (200) can identify the reference value (1204) based on the identified maximum and minimum values. The wearable device (200) can identify a second pattern (e.g., '10101') after a time interval (1216) based on the quantized digital signal (1212) and the reference value (1204).

[0202] Referring to FIG. 12C, the wearable device (200) can identify a second pattern based on a peak value of a light-receiving signal. For example, the wearable device (200) can change the light-receiving signal (1221) into a digital signal (1222) based on a sampling operation. The wearable device (200) can identify a peak value by identifying timings at which a value greater than a surrounding value of the digital signal (1222) does not exist. The wearable device (200) can identify time points (e.g., time points (1223), (1224), and (1225)) at which peak values ​​(or valley values) occur. The wearable device (200) can normalize the time intervals between the time points at which peak values ​​occur. The wearable device (200) can identify the second pattern based on the time intervals. For example, the value of the time interval between time points (1223) and (1224) can be identified as a first value (e.g., '1'). The value of the time interval between time points (1224) and (1225) can be identified as a second value (e.g., '0'). The method for identifying the second pattern described in Fig. 12c has a higher algorithmic complexity than the methods described in Figs. 12a and 12b, and requires a lot of sensing data, which may result in a longer sampling time. However, the method for identifying the second pattern described in Fig. 12c is robust to noise in the optical signal, so the second pattern can be identified more accurately.

[0203] According to the method illustrated in FIG. 12A and / or FIG. 12C, the color and brightness of the display (312) may change, or the display (312) may blink. Accordingly, an unnatural screen may be provided to the user. By changing the display cycle and increasing the sampling cycle, the light emission signal may be set so that the user does not perceive the change in the light emission signal.

[0204] According to an embodiment, the direction of the PPG sensor (327) may change depending on the direction in which the wearable device (200) is placed on the display (312). Accordingly, the electronic device (101) may output a light-emitting signal radially. The electronic device (101) may output a light-emitting signal not only inside the area in contact with the wearable device (200) but also outside the area, thereby improving the accuracy of the light-receiving signal identified by the wearable device (200).

[0205] FIG. 13 illustrates an example of the operation of an electronic device and multiple wearable devices when multiple wearable devices are positioned on a display of the electronic device.

[0206] Referring to FIG. 13, according to operations 1311 to 1321, the electronic device (101) can identify that a plurality of wearable devices are positioned on the display (312) of the electronic device (101). The electronic device (101) can display information about each of the plurality of wearable devices through the display (312). The plurality of wearable devices can include a first wearable device (1301) and a second wearable device (1302). Each of the first wearable device (1301) and the second wearable device (1302) can correspond to a wearable device (200).

[0207] In operation 1311, the electronic device (101) may establish a connection with the first wearable device (1301). In operation 1312, the electronic device (101) may establish a connection with the second wearable device (1302). For example, the electronic device (101) may establish a connection with the first wearable device (1301) and the second wearable device (1302) using short-range communication (e.g., Bluetooth, BLE, or wireless LAN). The order of operations 1311 and 1312 may be changed.

[0208] In steps 1311 and 1312, after the electronic device (101) establishes a connection with the first wearable device (1301) and the second wearable device (1302), the first wearable device (1301) and the second wearable device (1302) may be positioned on the display (312) of the electronic device (101). For example, the first wearable device (1301) may be positioned in a first area on the display (312) of the electronic device (101). The second wearable device (1302) may be positioned in a second area on the display (312) of the electronic device (101).

[0209] In operation 1313, the electronic device (101) can identify a first touch input of a specified shape and a second touch input of a specified shape. The electronic device (101) can identify a first touch input by a first wearable device (1301) in a first area. The electronic device (101) can identify a second touch input by a second wearable device (1302) in a second area. The electronic device (101) may not be able to identify whether a device located in the first area is the first wearable device (1301) or the second wearable device (1302). The electronic device (101) may not be able to identify whether a device located in the second area is the first wearable device (1301) or the second wearable device (1302). The electronic device (101) may perform the following operations to distinguish between devices located in the first area and the second area.

[0210] In operation 1314, the electronic device (101) may request the first wearable device (1301) to identify the light-emitting signal. For example, the electronic device (101) may transmit a signal to the first wearable device (1301) that causes the first wearable device (1301) to identify the light-emitting signal.

[0211] In operation 1315, the electronic device (101) may request the second wearable device (1302) to identify the light-emitting signal. For example, the electronic device (101) may transmit a signal to the second wearable device (1302) that causes the second wearable device (1302) to identify the light-emitting signal.

[0212] In operation 1316, the electronic device (101) may output a first light-emitting signal in a first region and a second light-emitting signal in a second region. For example, the first light-emitting signal may have a first pattern. The second light-emitting signal may have a third pattern. The electronic device (101) may output the first light-emitting signal based on the first pattern. The electronic device (101) may output the second light-emitting signal based on the third pattern.

[0213] In operation 1317, the first wearable device (1301) is positioned in a first area on the display (312) of the electronic device (101), and thus can identify a first light-emitting signal having a first pattern. Based on the first light-emitting signal, the first wearable device (1301) can identify the first light-receiving signal using a light-receiving circuit (or one or more light-receiving circuits) of the first wearable device (1301). The first light-receiving signal can have a second pattern. The first wearable device (1301) can identify the second pattern of the first light-receiving signal.

[0214] In operation 1318, the second wearable device (1302) is positioned in the second area on the display (312) of the electronic device (101), and thus can identify the second light-emitting signal having the third pattern. Based on the second light-emitting signal, the second wearable device (1302) can identify the second light-receiving signal using a light-receiving circuit (or one or more light-receiving circuits) of the second wearable device (1302). The second light-receiving signal can have a fourth pattern. The second wearable device (1302) can identify the fourth pattern of the second light-receiving signal.

[0215] In operation 1319, the first wearable device (1301) may transmit information about the first light-receiving signal to the electronic device (101). The electronic device (101) may receive information about the first light-receiving signal from the first wearable device (1301). The information about the first light-receiving signal may include information about the second pattern and / or information about the identifier of the first wearable device (1301).

[0216] The electronic device (101) can identify that the second pattern corresponds to the first pattern. Based on the second pattern corresponding to the first pattern, the electronic device (101) can identify that the first wearable device (1301) is located in the first area.

[0217] In operation 1320, the second wearable device (1302) may transmit information about the second light-receiving signal to the electronic device (101). The electronic device (101) may receive information about the second light-receiving signal from the second wearable device (1302). The information about the second light-receiving signal may include information about the fourth pattern and / or information about the identifier of the second wearable device (1302).

[0218] The electronic device (101) can identify that the fourth pattern corresponds to the third pattern. Based on the fourth pattern corresponding to the third pattern, the electronic device (101) can identify that the second wearable device (1302) is located in the second area.

[0219] In operation 1321, the electronic device (101) can display information about the first wearable device (1301) through a first user interface including a first area. The electronic device (101) can display information about the second wearable device (1302) through a second user interface including a second area. Operations for displaying information about the first wearable device (1301) and operations for displaying information about the second wearable device (1302) can be performed independently.

[0220] FIG. 14 illustrates an example of the operation of an electronic device, an external electronic device, and a wearable device when the wearable device is connected to an external electronic device.

[0221] Referring to FIG. 14, the electronic device (101) may not be connected to the wearable device (200). The wearable device (200) may be connected to an external electronic device (1401). Depending on the embodiment, the user of the wearable device (200) and the user of the electronic device (101) may be distinguished. For example, an account registered in the wearable device (200) and an account registered in the electronic device (101) may be different from each other.

[0222] In operation 1411, the wearable device (200) may establish a connection with an external electronic device (1401). A connection between the electronic device (101) and the wearable device (200) may not be established.

[0223] In a state where a connection between the electronic device (101) and the wearable device (200) is not established, the wearable device (200) can be positioned on the display (312) of the electronic device (101).

[0224] In operation 1412, the electronic device (101) can identify a touch input of a specified shape. For example, the electronic device (101) can identify a touch input of a specified shape based on identifying that at least one touch point forms a specified shape.

[0225] In operation 1413, the electronic device (101) may transmit a signal to an external electronic device (1401) to notify that a wearable device recognition procedure will be performed. The external electronic device (1401) may receive a signal from the electronic device (101) to notify that a wearable device recognition procedure will be performed.

[0226] For example, when the electronic device (101) and the external electronic device (1401) are not connected, the electronic device (101) may transmit a signal based on broadcasting to notify that a wearable device recognition procedure will be performed. For example, the electronic device (101) may transmit a signal based on broadcasting to notify peripheral devices including the external electronic device (1401) that a wearable device recognition procedure will be performed.

[0227] According to an embodiment, when an electronic device (101) and an external electronic device (1401) are connected, the electronic device (101) may request the external electronic device (1401) connected to the electronic device (101) to identify a light-emitting signal emitted from an area corresponding to a touch input. The electronic device (101) may transmit a signal to the external electronic device (1401) to request the external electronic device (1401) to identify a light-emitting signal emitted from an area corresponding to the touch input. According to an embodiment, the electronic device (101) may transmit a signal to the external electronic device (1401) to inform that a wearable device recognition procedure will be performed.

[0228] In operation 1414, the external electronic device (1401) may request the wearable device (200) connected to the external electronic device (1401) to identify a light-emitting signal output from the electronic device (101). The external electronic device (1401) may transmit a signal to the wearable device (200) that causes the wearable device (200) to identify the light-emitting signal output from the electronic device (101).

[0229] For example, the external electronic device (1401) can identify whether there is a wearable device connected to the external electronic device (1401). The external electronic device (1401) can identify that the wearable device (200) is connected to the external electronic device (1401).

[0230] An external electronic device (1401) can identify whether a wearable device (200) connected to the external electronic device (1401) is worn by a user. Based on identifying that the wearable device (200) is not worn by a user, the external electronic device (1401) can request the wearable device (200) to identify a light-emitting signal output from the electronic device (101). Based on identifying that the wearable device (200) is worn by a user, the external electronic device (1401) can identify that the wearable device (200) is not positioned on the display (312) of the electronic device (101). Therefore, the external electronic device (1401) can request the wearable device (200) to identify a light-emitting signal output from the electronic device (101) only when the wearable device (200) is not worn by a user.

[0231] In operation 1415, the wearable device (200) can identify a light-emitting signal by identifying external light based on a request received from an external electronic device (1401). The wearable device (200) can obtain a light-receiving signal based on the light-emitting signal. The wearable device (200) can identify a second pattern for the light-receiving signal.

[0232] In operation 1416, the wearable device (200) may transmit information about a light-receiving signal identified in the wearable device (200) to an external electronic device (1401). The external electronic device (1401) may receive information about the light-receiving signal identified in the wearable device (200) from the wearable device (200). For example, the information about the light-receiving signal may indicate a second pattern regarding the light-receiving signal.

[0233] In some embodiments, the above-described operation 1415 may not be performed. For example, the wearable device (200) may detect a light-emitting signal based on a request for identification of a light-emitting signal. The wearable device (200) may transmit information indicating that the light-emitting signal has been detected to an external electronic device (1401). The information indicating that the light-emitting signal has been detected may be an example of information about a light-receiving signal. For example, the wearable device (200) may not identify a second pattern for the light-receiving signal, but may transmit only information indicating that the light-emitting signal has been detected to the external electronic device.

[0234] In operation 1417, the external electronic device (1401) may transmit information about a light-receiving signal received from the wearable device (200) to the electronic device (101). For example, the external electronic device (1401) may transmit authentication information of the wearable device (200) to the electronic device (101) together with information about the light-receiving signal received from the wearable device (200). The electronic device (101) may receive information about the light-receiving signal and authentication information about the wearable device (200) from the external electronic device (1401).

[0235] In operation 1418, the electronic device (101) may display information about the wearable device (200). For example, the electronic device (101) may identify that a device located on the display (312) of the electronic device (101) is the wearable device (200) based on identifying that a second pattern regarding a light-receiving signal identified in the wearable device (200) corresponds to a first pattern regarding a light-emitting signal. The electronic device (101) may display information about the wearable device (200) through a user interface that includes an area corresponding to a touch input. For example, the electronic device (101) may establish a connection with an external electronic device (1401). The electronic device (101) may receive information about the wearable device (200) from the external electronic device (1401) and display the received information about the wearable device (200) through the display (312).

[0236] FIG. 15A illustrates an example of the operation of an electronic device, an external electronic device, and a plurality of wearable devices when a plurality of wearable devices are positioned on a display of the electronic device.

[0237] Referring to FIG. 15A, in operation 1501, the electronic device (101) may establish a connection with the first wearable device (1301). Operation 1501 may correspond to operation 1311 of FIG. 13.

[0238] In operation 1502, an external electronic device (1401) may establish a connection with a second wearable device (1302). Operation 1502 may correspond to operation 1411 of FIG. 14.

[0239] After the first wearable device (1301) is connected to the electronic device (101) and the second wearable device (1302) is connected to the external electronic device (1401), the first wearable device (1301) can be positioned in a first area on the display (312) of the electronic device (101). After the first wearable device (1301) is connected to the electronic device (101) and the second wearable device (1302) is connected to the external electronic device (1401), the second wearable device (1302) can be positioned in a second area on the display (312) of the electronic device (101).

[0240] In operation 1503, the electronic device (101) can identify a first touch input of a specified shape and a second touch input of a specified shape. The electronic device (101) can identify a first touch input by a first wearable device (1301) in a first area. The electronic device (101) can identify a second touch input by a second wearable device (1302) in a second area. The electronic device (101) may not be able to identify whether a device located in the first area is the first wearable device (1301) or the second wearable device (1302). The electronic device (101) may not be able to identify whether a device located in the second area is the first wearable device (1301) or the second wearable device (1302). The electronic device (101) may perform the following operations to distinguish between devices located in the first area and the second area.

[0241] In operation 1504, the electronic device (101) may request the first wearable device (1301) connected to the electronic device (101) to identify the light-emitting signal. For example, the electronic device (101) may transmit a signal to the first wearable device (1301) that causes the first wearable device (1301) to identify the light-emitting signal. Operation 1504 may correspond to operation 1314 of FIG. 13.

[0242] In operation 1505, the electronic device (101) may transmit a signal to an external electronic device (1401) to notify that a wearable device recognition procedure will be performed.
