[0007] According to one embodiment, by including a plurality of magnets or one or more Hall sensors on the rear of the electronic device, the orientation (or position) of an external device (e.g., an accessory) tagged (or attached) to the electronic device can be identified.

[0008] In one embodiment, different applications can be run on the electronic device, or specific functions of an application can be executed directly, based on the direction (or location) of an external device tagged to the electronic device.

[0009] According to one embodiment, by arranging a plurality of magnetic bodies in a regular polygon, space for an antenna included in an electronic device can be secured, and the design structure of the electronic device can be efficiently implemented.

[0010] According to one embodiment, by enabling an external device to be attached to an electronic device in various directions according to the purpose of the external device, the user's convenience can be improved by simply attaching the external device to a specific location on the electronic device to immediately launch a desired application.

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, a corresponding communication module may communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as NFC (near field communication), RFID (radio frequency identification), BLE (bluetooth low energy), UWB (ultra-wideband), Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) 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 may be integrated into a single component (e.g., a single chip) or implemented as a plurality of separate components (e.g., multiple chips).The wireless communication module (192) can verify or authenticate an electronic device (101) within a communication network, such as a first network (198) or a second network (199), using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0056] 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.

For example, the four magnetic bodies (201, 203, 205, 207) may be arranged in different directions around the wireless charging coil (219). The four magnetic bodies (201, 203, 205, 207) can be formed in a regular polygonal arrangement structure at the same distance from the center of the wireless charging coil (219). When the four magnetic bodies (201, 203, 205, 207) are arranged in a regular polygonal arrangement, there is more empty space compared to a circular arrangement, making it easier to secure space for the antenna and design it.

[0070] The Hall sensor (or magnetic detection sensor) is for detecting a change in the magnetic field of at least one of the four magnetic bodies (201, 203, 205, 207), and may be arranged to correspond to (or be adjacent to) the four magnetic bodies (201, 203, 205, 207). For example, the first Hall sensor (211) may be arranged at a position corresponding to the first magnetic body (201), and the second Hall sensor (213) may be arranged at a position corresponding to the fourth magnetic body (207). Alternatively, unlike the drawing, the two Hall sensors (211, 213) may be arranged adjacent to (or be adjacent to) the second magnetic body (203) or the third magnetic body (205). The drawing is only to help understanding of the invention, and the invention is not limited by the drawing.

[0071] In a second embodiment (220), the electronic device (101) may include four magnetic bodies (201, 203, 205, 207) and four Hall sensors (211, 213, 215, 217). The first magnetic body (201), the second magnetic body (203), the third magnetic body (205), and the fourth magnetic body (207) may be arranged to have a distance apart from each other. For example, the first magnetic body (201), the second magnetic body (203), the third magnetic body (205), and the fourth magnetic body (207) may be arranged in different directions around the wireless charging coil (219). Four Hall sensors (211, 213, 215, 217) may be arranged to correspond to four magnetic bodies (201, 203, 205, 207). For example, the first Hall sensor (211) may be arranged at a position corresponding to the first magnetic body (201), the second Hall sensor (213) may be arranged at a position corresponding to the fourth magnetic body (207), the third Hall sensor (215) may be arranged at a position corresponding to the second magnetic body (203), and the fourth Hall sensor (217) may be arranged at a position corresponding to the third magnetic body (205).

[0072] In a third embodiment (230), the electronic device (101) may include four magnetic bodies (201, 203, 205, 207). The first magnetic body (201), the second magnetic body (203), the third magnetic body (205), and the fourth magnetic body (207) may be arranged to have a distance apart from each other. For example, the first magnetic body (201), the second magnetic body (203), the third magnetic body (205), and the fourth magnetic body (207) may be arranged in different directions around the wireless charging coil (219). The electronic device (101) may not include a Hall sensor. In this case, an external device (e.g., an external device (400) of FIG. 4A) tagged (or contacted, mounted, or attached) to the electronic device (101) may include a Hall sensor.

[0073] In a fourth embodiment (240), the electronic device (101) may include three magnetic bodies (201, 203, 207) and at least one Hall sensor (e.g., a second Hall sensor (213)). The first magnetic body (201), the second magnetic body (203), and the fourth magnetic body (207) may be arranged to have a distance apart from each other. For example, the first magnetic body (201), the second magnetic body (203), and the fourth magnetic body (207) may be arranged in different directions around the wireless charging coil (219). The second Hall sensor (213) may be arranged to correspond to (or be adjacent to) the fourth magnetic body (207). Alternatively, unlike the drawing, the electronic device (101) may only include the first Hall sensor (211) corresponding to the first magnetic body (201). The drawings are provided only to aid understanding of the invention and the invention is not limited by the drawings.

[0074] In one embodiment, each of the plurality of magnetic bodies (201, 203, 205, 207) may be formed in a structure in which the outer S magnetic body radially wraps around the inner N magnetic body so that the S magnetism is directed toward the direction of the inner N magnetic body. For example, each of the plurality of magnetic bodies (201, 203, 205, 207) may be arranged in a Halbach array. However, the plurality of magnetic bodies (201, 203, 205, 207) may have a magnetic body arrangement other than the Halbach array.

[0075] According to one embodiment, the electronic device (101) may further include a wireless charging coil (219) and an NFC (near field communication) antenna (209). Although the drawing illustrates that the NFC antenna (209) (or NFC communication module) is arranged in a circular shape surrounding the wireless charging coil (219), the NFC antenna (209) may also be formed in a rectangular shape adjacent to a side (or corner) of the electronic device (101). The arrangement position and formed size of the wireless charging coil (219) or NFC antenna (209) included in the electronic device (101) may be different from those illustrated. The drawings are provided only to aid understanding of the invention, and the invention is not limited by the drawings.

[0076] FIG. 2b is an exploded perspective view illustrating an example of an electronic device with a magnet and a Hall sensor attached thereto according to one embodiment.

[0077] Referring to FIG. 2B, the electronic device (101) has substantially the same components as the electronic device (101) described in the previous drawing, and the same reference numerals are given to the same components, and a detailed description thereof may be omitted. The electronic device (101) may include a display module (260) (e.g., the display module (160) of FIG. 1) under the front glass (251), and a battery and a main board (270) under the display module (260). The electronic device (101) may include a module case (280) and a wireless charging coil (219) corresponding to a plurality of magnetic bodies (201 to 207) inside the frame (253). The electronic device (101) may include (or arrange) a plurality of magnetic bodies (201 to 207) in the rear cover (255).

[0078] FIG. 3 is a drawing illustrating an example of arranging a Hall sensor corresponding to a magnetic material arranged in an electronic device according to one embodiment.

[0079] Referring to FIG. 3, an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1) may include a plurality of magnetic bodies (or magnet modules) (201, 203, 205, 207) and a plurality of Hall sensors (211, 213, 215, 217) on the rear surface. In FIG. 3, when the electronic device (101) is implemented as the second embodiment (220) of FIG. 2a, an example of the arrangement of the plurality of Hall sensors (211, 213, 215, 217) may be described. However, the same or similar arrangement may also be applied when the electronic device (101) is implemented as the first embodiment (210) of FIG. 2a or the fourth embodiment (240).

[0080] In the first embodiment (310), a plurality of Hall sensors (211, 213, 215, 217) may be arranged adjacent to a plurality of magnetic bodies (201, 203, 205, 207). The Hall sensors are for detecting changes in the magnetic field of the magnetic bodies, and the plurality of Hall sensors (211, 213, 215, 217) may be arranged to correspond to the plurality of magnetic bodies (201, 203, 205, 207). When a plurality of Hall sensors (211, 213, 215, 217) are arranged adjacent to a plurality of magnetic bodies (201, 203, 205, 207), a separate shielding member may not be formed between the plurality of Hall sensors (211, 213, 215, 217) and the plurality of magnetic bodies (201, 203, 205, 207).

[0081] In a second embodiment (320), the plurality of Hall sensors (211, 213, 215, 217) may be arranged in a direction perpendicular to the plurality of magnetic bodies (201, 203, 205, 207). For example, referring to the first attachment cross-section (340), when the plurality of magnetic bodies (201, 203, 205, 207) are arranged on the rear cover of the electronic device (101) (e.g., the rear cover (255) of FIG. 2B), the plurality of Hall sensors (211, 213, 215, 217) may be arranged in a direction below the plurality of magnetic bodies (201, 203, 205, 207) in the front direction of the electronic device (101). In this case, the plurality of Hall sensors (211, 213, 215, 217) may further include a shielding member between the plurality of magnetic bodies (201, 203, 205, 207).

[0082] Looking at the first attachment cross-section (340), a first Hall sensor (211) may be placed under the first magnetic body (201), and a third Hall sensor (215) may be placed under the second magnetic body (203). When the first magnetic body (401) of the external device (400) is attached to the first magnetic body (201) of the electronic device (101), the first Hall sensor (211) can detect a change in the magnetic field strength or wavelength of the first magnetic body (201). When the second magnetic body (403) of the external device (400) is attached to the second magnetic body (203) of the electronic device (101), the third Hall sensor (215) can detect a change in the magnetic field strength or wavelength of the second magnetic body (203).

[0083] In a third embodiment (330), the plurality of Hall sensors (211, 213, 215, 217) may be arranged (or included) within the plurality of magnetic bodies (201, 203, 205, 207). For example, referring to the second attachment cross-section (350), the plurality of Hall sensors (211, 213, 215, 217) may be arranged within (e.g., in the center) the plurality of magnetic bodies (201, 203, 205, 207). In this case, the plurality of Hall sensors (211, 213, 215, 217) may further include a shielding member between the plurality of magnetic bodies (201, 203, 205, 207).

[0084] Looking at the second attachment cross-section (350), a first Hall sensor (211) may be placed under the first magnetic body (201), and a third Hall sensor (215) may be placed under the second magnetic body (203). When the first magnetic body (401) of the external device (400) is attached to the first magnetic body (201) of the electronic device (101), the first Hall sensor (211) can detect a change in the magnetic field strength or wavelength of the first magnetic body (201). When the second magnetic body (403) of the external device (400) is attached to the second magnetic body (203) of the electronic device (101), the third Hall sensor (215) can detect a change in the magnetic field strength or wavelength of the second magnetic body (203).

[0085] FIG. 4A is a drawing illustrating an example of a magnetic body and a Hall sensor attached to an external device according to one embodiment.

[0086] Referring to FIG. 4A, an external device (400) according to an embodiment may be a type of accessory that can be attached to an electronic device (e.g., the electronic device (101) of FIG. 1). According to an embodiment, the external device (400) may include at least one of a stand including a wireless charging pad, a car cradle, a tripod mount, a lighting device, a photography filter, or an electronic pen. The external device (400) may include a plurality of magnetic bodies (or magnet modules) (401, 403, 405, 407) or at least one Hall sensor (411, 413) (e.g., the sensor module (176) of FIG. 1). In order to distinguish the magnetic body included in the external device (400) from the magnetic body included in the electronic device (101), the magnetic body included in the external device (400) may be hereinafter described as an 'external magnetic body'. However, the present invention is not limited by the description. The external device (400) can store device information of the external device (400), including the name (or identifier) ​​or type of the external device (400), in the memory.

[0087] In a first embodiment (410), the external device (400) may include at least one of four external magnetic bodies (401, 403, 405, 407), an NFC tag (409) (or an NFC antenna, an NFC communication module), and a wireless charging coil (419). The four external magnetic bodies (401, 403, 405, 407) may include a first external magnetic body (401), a second external magnetic body (403), a third external magnetic body (405), and a fourth external magnetic body (407). The four external magnetic bodies (401, 403, 405, 407) may be arranged to have a distance apart from each other. For example, the four external magnetic bodies (401, 403, 405, 407) may be arranged in different directions around the wireless charging coil (419). The four external magnetic bodies (401, 403, 405, 407) can be formed in a regular polygonal arrangement structure at the same distance from the center of the wireless charging coil (419). When the four external magnetic bodies (401, 403, 405, 407) are arranged in a regular polygon, there is more empty space compared to a circular arrangement, so securing space for the antenna and design can be made easy. The external device (400) can detect that it is tagged (or in contact with, attached to) the electronic device (101) through the NFC tag (409). The external device (400) can transmit (or share) power to the electronic device (101) through the wireless charging coil (419).

The four external magnetic bodies (401, 403, 405, 407) may be arranged to have a distance apart from each other. For example, four external magnets (401, 403, 405, 407) can be arranged in different directions around the wireless charging coil (419).

[0089] The two external Hall sensors (411, 413) may be arranged to correspond to (or be adjacent to) the four external magnetic bodies (401, 403, 405, 407). For example, the first external Hall sensor (411) may be arranged at a position corresponding to the first external magnetic body (401), and the second Hall sensor (413) may be arranged at a position corresponding to the fourth external magnetic body (407). Alternatively, unlike the drawing, the two external Hall sensors (411, 413) may be arranged adjacent to (or be adjacent to) the second external magnetic body (403) or the third external magnetic body (405). The drawing is only to help understanding of the invention, and the invention is not limited by the drawing.

The four external magnetic bodies (401, 403, 405, 407) may be arranged to have a distance apart from each other. For example, four external magnets (401, 403, 405, 407) may be arranged in different directions around the wireless charging coil (419). Four external Hall sensors (411, 413, 415, 417) may be arranged to correspond to the four external magnets (401, 403, 405, 407). For example, the first external Hall sensor (411) may be arranged at a position corresponding to the first external magnet (401), the second external Hall sensor (413) may be arranged at a position corresponding to the fourth external magnet (407), the third external Hall sensor (415) may be arranged at a position corresponding to the second external magnet (403), and the fourth external Hall sensor (417) may be arranged at a position corresponding to the third external magnet (405).

[0091] In a fourth embodiment (440), the external device (400) may include at least one of four external magnetic bodies (401, 403, 405, 407) and an NFC tag (409). The four external magnetic bodies (401, 403, 405, 407) may include a first external magnetic body (401), a second external magnetic body (403), a third external magnetic body (405), and a fourth external magnetic body (407). The four external magnetic bodies (401, 403, 405, 407) may be arranged to have a distance apart from each other.

[0092] In one embodiment, each of the plurality of external magnetic bodies (401, 403, 405, 407) may be formed in a structure in which the inner S magnetic body radially wraps around the outer N magnetic body so that the S magnetism is oriented in the direction of the outer N magnetic body. For example, each of the plurality of external magnetic bodies (401, 403, 405, 407) may be arranged in a Halbach arrangement. However, the plurality of external magnetic bodies (401, 403, 405, 407) may have a magnetic body arrangement other than the Halbach arrangement.

[0093] FIG. 4b is an exploded perspective view illustrating an example of an external device with a magnet and a Hall sensor attached thereto according to one embodiment.

[0094] Referring to FIG. 4B, the external device (400) has substantially the same components as the external device (400) described in the previous drawing, and the same reference numerals are given to them, and a detailed description thereof may be omitted. The external device (400) may include a cover (451), a module case (460), a PCB board (470), and a case (453). The module case (460) may include (or arrange) a plurality of external magnetic materials (401 to 407) and a wireless charging coil (419). Depending on the embodiment, the module case (460) may further include an external Hall sensor (e.g., a first external Hall sensor (211) or an NFC antenna (209).

[0095] FIG. 5 is a diagram illustrating an example of controlling an operation when an external device is tagged to an electronic device according to one embodiment.

[0096] Referring to FIG. 5, an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1) can detect that an external device (e.g., the external device (400) of FIG. 4A) is tagged (or contacted, attached). To this end, the electronic device (101) can be implemented as one of the first embodiment (210) to the fourth embodiment (240) of FIG. 3A. The external device (400) can be implemented as at least one of the first embodiment (410) to the fourth embodiment (440) of FIG. 4A.

[0097] As in the first attachment example (510), when the external device (400) is vertically attached (or tagged) to the electronic device (101), the electronic device (101) may provide a first user interface (550). The electronic device (101) may detect a change in a magnetic field of at least one of a plurality of magnetic bodies (e.g., the first magnetic body (201) to the fourth magnetic body (207) of FIG. 3A) using at least one Hall sensor (e.g., the first Hall sensor (211) to the fourth Hall sensor (217) of FIG. 3A). The electronic device (101) may identify (or determine) that the external device (400) is vertically attached based on the detected change in the magnetic field. For example, when the external device (400) is a wireless charging pad holder, the first user interface (550) may include a notification (or pop-up) for executing a wireless charging (or low-power charging) function (or mode). The electronic device (101) can perform wireless charging based on user input through the first user interface (550).

[0098] As in the second attachment example (530), when the external device (400) is attached horizontally to the electronic device (101), the electronic device (101) can provide a second user interface (570). The electronic device (101) can detect a change in the magnetic field of at least one of a plurality of magnetic bodies (e.g., the first magnetic body (201) to the fourth magnetic body (207) of FIG. 3A) using at least one Hall sensor (e.g., the first Hall sensor (211) to the fourth Hall sensor (217) of FIG. 3A). The electronic device (101) can identify (or determine) that the external device (400) is attached horizontally based on the detected change in the magnetic field. For example, when the external device (400) is a wireless charging pad holder, the second user interface (550) can include an application list related to a video streaming service or an execution screen of an application. The electronic device (101) can provide a video streaming service while wirelessly charging based on user input through the second user interface (570).

The instructions, when executed by the processor, may cause the electronic device to detect a change in a magnetic field of at least one of the plurality of magnetic bodies using the one or more Hall sensors, and to control an operation of the electronic device based on the detected change in the magnetic field.

[0100] The one or more Hall sensors may be included in numbers less than, more than, or corresponding to the number of the plurality of magnetic bodies.

[0101] The electronic device further includes a display module (260), and the one or more Hall sensors are disposed under the display module, and the plurality of magnetic bodies are disposed to overlap vertically under the one or more Hall sensors disposed under the display module, or the one or more Hall sensors disposed under the display module may be formed so as to be disposed inside the plurality of magnetic bodies.

[0102] Each of the above plurality of magnetic materials can be configured to be arranged in a Halbach array.

[0103] The electronic device further includes a wireless charging coil and a short-range wireless communication module arranged to surround the wireless charging coil, and the plurality of magnetic bodies may be configured to be arranged around the short-range wireless communication module.

[0104] The above instructions, when executed by the processor, may cause the electronic device to detect tagging of an external device using the short-range wireless communication module and to identify the external device.

[0105] The electronic device further includes a display module (260), and the instructions, when executed by the processor, can cause the electronic device to display information of the identified external device on the display module.

[0106] The instructions, when executed by the processor, may cause the electronic device to detect a change in a magnetic field through the one or more Hall sensors when tagging of an external device is detected, identify an attached position of the external device based on the detected change in the magnetic field, and execute an application based on the identified attached position of the external device.

[0107] The above instructions, when executed by the processor, may cause the electronic device to connect to the external device via low-power Bluetooth and transmit a command associated with the executed application to the external device via the low-power Bluetooth.

[0108] The instructions, when executed by the processor, may cause the electronic device to detect a change in a magnetic field through the one or more Hall sensors when tagging of an external device is detected, identify an attachment location of the external device based on the detected change in the magnetic field, execute a first function of an application when the identified attachment location is a first location, and execute a second function of the application when the identified attachment location is a second location, or execute a first application when the identified attachment location is the first location, and execute a second application when the identified attachment location is the second location.

[0110] The above instructions, when executed by the processor, may cause the electronic device to collect a usage history of the electronic device while it is attached to the external device, and to execute an application differently depending on the attached position of the external device by further considering the collected usage history of the electronic device.

[0111] The instructions, when executed by the processor, may cause the electronic device to execute a specific application based on at least one of a type of an external device tagged to the electronic device, an attached position of the external device, an attached location of the external device, a movement trajectory of the external device, or a usage history of the electronic device.

The electronic device (101) may display information about the external device (400) while the external device (400) is attached.

[0116] In operation 607, the electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) through the Hall sensor (213). The electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) through the Hall sensor (213) while the external device (400) is attached. The electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) by including two Hall sensors (211, 213) or by using four Hall sensors (211 to 217). Hereinafter, the electronic device (101) can be described as including four Hall sensors (211 to 217). However, the present invention is not limited by the description. The plurality of magnetic bodies (201 to 207) included in the electronic device (101) may be formed in a structure in which the outer S magnetic body radially wraps around the inner N magnetic body so that the S magnetism is directed toward the direction of the magnetic body. The plurality of external magnetic bodies (401 to 407) included in the external device (400) may be formed in a structure in which the inner S magnetic body radially wraps around the outer N magnetic body so that the S magnetism is directed toward the direction of the magnetic body. The four Hall sensors (211 to 217) may detect changes in the intensity and wavelength of the magnetic field when the plurality of magnetic bodies (201 to 207) are tagged (or attached) to the plurality of external magnetic bodies (401 to 407) included in the external device (400).

[0117] In operation 609, the electronic device (101) can identify the attached position of the external device (400). The attached position (or attachment direction, tagging mode) may indicate whether the external device (400) is attached to the electronic device (101) in a horizontal direction (or horizontal direction) or a vertical direction (or vertical direction). For example, when the electronic device (101) includes two Hall sensors (211, 213), at least two magnetic bodies (401, 407) of the external device (400) may have a magnetic field strength stronger than that of the remaining two magnetic bodies (403, 405). This may be for identifying the attached position of the external device (400) with the two Hall sensors (211, 213). Alternatively, when the electronic device (101) includes four Hall sensors (211 to 217), the electronic device (101) can identify the attached position of the external device (400) based on the magnetic field changes caused by the plurality of magnetic bodies (201 to 207). The electronic device (101) can identify the attached position of the external device (400) while the external device (400) is attached.

[0118] In operation 611, the electronic device (101) can execute an application according to the attached position of the external device (400). For example, if the external device (400) is a wireless charging pad holder, and the electronic device (101) is attached to the electronic device (101) in a vertical direction, the electronic device (101) can execute an application (or pop-up, notification) related to wireless charging, and if the external device (400) is attached to the electronic device (101) in a horizontal direction, the electronic device (101) can execute an application related to a video streaming service. For example, if the external device (400) is a car cradle, and the electronic device (101) is attached to the electronic device (101) in a vertical direction, the electronic device (101) can execute a map application, and if the external device (400) is attached to the electronic device (101) in a horizontal direction, the electronic device (101) can execute an application related to a music streaming service. The electronic device (101) can execute an application according to the attached position of the external device (400) while the external device (400) is attached.

[0119] According to one embodiment, the electronic device (101) collects the usage history of the electronic device (101) after attaching the external device (400), and further considers the collected usage history of the electronic device (101) to execute applications differently according to the attached position of the external device (400). Each user may have a different pattern of using the electronic device (101) after attaching the external device (400). The electronic device (101) may execute an application that provides a desired function to the user so that the user can immediately perform the desired function without additional input from the user based on the usage history of the electronic device (101). The electronic device (101) may execute various applications or execute specific functions of the applications without additional user input depending on what the external device (400) is or the attached position of the external device (400).

[0120] In operation 613, the electronic device (101) may transmit a command (or instruction) associated with the executed application to the external device (400). To perform operation 613, the electronic device (101) may be connected to the external device (400) via low-power Bluetooth prior to operation 613. For example, the command may be to start wireless charging or turn on a light source. However, when the external device (400) is tagged to the electronic device (101) or when wireless charging is automatically started or the light source is turned on after a certain period of time, operation 613 may be omitted. The electronic device (101) may transmit a command (or instruction) associated with the executed application to the external device (400) while the external device (400) is attached.

[0121] FIG. 7 is a flowchart (700) illustrating an operating method of an electronic device according to one embodiment.

[0122] Referring to FIG. 7, in operation 701, a processor (e.g., the processor (120) of FIG. 1) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to an embodiment may detect and identify an external device (e.g., the external device (400) of FIG. 4A). According to an embodiment, the external device (400) may include at least one of a stand including a wireless charging pad, a car cradle, a tripod mount, a lighting device, a photography filter, or an electronic pen. The external device (400) may include a plurality of external magnetic bodies (or magnet modules) (e.g., a plurality of magnetic bodies (401, 403, 405, 407) of FIG. 4A) and an NFC tag (e.g., the NFC tag (409) of FIG. 4A). Alternatively, depending on the embodiment, the external device (400) may further include a wireless charging coil (e.g., wireless charging coil (419) of FIG. 4A) or at least one Hall sensor (e.g., at least one Hall sensor (411, 413) of FIG. 4A) (e.g., sensor module (176) of FIG. 1).

[0123] The electronic device (101) may include a plurality of magnetic bodies (e.g., a plurality of magnetic bodies (201 to 207) of FIG. 2A), at least one Hall sensor (e.g., a plurality of Hall sensors (211 to 217) of FIG. 2A), a wireless charging coil (e.g., a wireless charging coil (219) of FIG. 2A), and an NFC antenna (e.g., an NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) using the NFC antenna (e.g., the NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) when the NFC tag (409) of the external device (400) corresponds to the NFC antenna (209). The processor (120) may read tag information (or tag value) of the external device (400) to identify the external device (400). The tag of the external device (400) The information may be pre-stored in the external device (400). The tag information may include device information of the external device (400). The device information of the external device (400) may include the name (or identifier) ​​or type of the external device (400).

[0124] In operation 703, the processor (120) may display information about the external device (400). The processor (120) may guide the user on a display (e.g., the display module (160) of FIG. 1) that the external device (400) is at least one of a wireless charging stand, a car cradle, a tripod mount, a lighting device, a photographic filter, or an electronic pen. The processor (120) may display information about the external device (400) while the external device (400) is attached.

[0125] In operation 705, the processor (120) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) through the Hall sensor (213). The electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) by including two Hall sensors (211, 213) or by using four Hall sensors (211 to 217). The plurality of magnetic bodies (201 to 207) included in the electronic device (101) can be formed in a structure in which an outer S magnetic body radially wraps an inner N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). The plurality of outer magnetic bodies (401 to 407) included in the external device (400) can be formed in a structure in which an inner S magnetic body radially wraps an outer N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). Each Hall sensor can detect changes in the intensity and wavelength of a magnetic field when multiple magnetic bodies (201 to 207) are tagged to multiple external magnetic bodies (401 to 407) included in an external device (400). Each Hall sensor can transmit the detected change in the magnetic field to the processor (120). Alternatively, the processor (120) can read the detected change in the magnetic field from each Hall sensor. The processor (120) can detect the magnetic fields of the multiple magnetic bodies (201 to 207) through the Hall sensors (213) while the external device (400) is attached.

[0126] In operation 707, the processor (120) may identify the attached position of the external device (400). The attached position (or attachment direction, tagging mode) may indicate whether the external device (400) is attached to the electronic device (101) in a horizontal direction (or horizontal direction) or a vertical direction (or vertical direction). For example, if the electronic device (101) includes two Hall sensors (211, 213), at least two magnetic bodies (401, 407) of the external device (400) may have a magnetic field strength stronger than that of the remaining two magnetic bodies (403, 405). This may be for identifying the attached position of the external device (400) with the two Hall sensors (211, 213). An example of identifying the attached position of an external device (400) using two Hall sensors (211, 213) will be described in detail with reference to the drawings below. Alternatively, when the electronic device (101) includes four Hall sensors (211 to 217), the processor (120) can identify the attached position of the external device (400) based on changes in magnetic fields caused by a plurality of magnetic bodies (201 to 207). The processor (120) can identify the attached position of the external device (400) while the external device (400) is attached.

[0127] In operation 709, the processor (120) may execute an application according to the attached position of the external device (400). For example, if the external device (400) is a wireless charging pad holder, and the processor (120) is attached to the electronic device (101) in a vertical direction, the processor may execute an application (or a pop-up, a notification) related to wireless charging, and if the external device (400) is attached to the electronic device (101) in a horizontal direction, the processor may execute an application related to a video streaming service. For example, if the external device (400) is a car cradle, and the processor (120) is attached to the electronic device (101) in a vertical direction, the processor (120) may execute a map application, and if the external device (400) is attached to the electronic device (101) in a horizontal direction, the processor may execute an application related to a music streaming service. The processor (120) can execute an application according to the attached position of the external device (400) while the external device (400) is attached.

[0128] According to one embodiment, the processor (120) collects the usage history of the electronic device (101) after attaching the external device (400), and may execute applications differently according to the attached position of the external device (400) by further considering the collected usage history of the electronic device (101). Each user may have a different pattern of using the electronic device (101) after attaching the external device (400). The processor (120) may execute an application that provides a desired function to the user so that the user can immediately perform the desired function without additional input from the user based on the usage history of the electronic device (101).

[0129] FIG. 8A is a diagram illustrating an example of identifying an attached position of an external device in an electronic device according to one embodiment.

[0130] Referring to FIG. 8A, when an electronic device (e.g., the electronic device (101) of FIG. 1) according to an embodiment includes four magnetic bodies (e.g., the four magnetic bodies (201 to 207) of FIG. 2A) and two Hall sensors (e.g., the first Hall sensor (211) and the second Hall sensor (213) of FIG. 2A) (e.g., the first embodiment (210) of FIG. 2A), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4A) (shaded) of an external device (e.g., the external device (400) of FIG. 4A)) may be formed to have a magnetic field intensity stronger than the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4A).

[0131] A first attachment example (810) may be one in which an external device (400) is attached to an electronic device (101) in a first direction (e.g., front). A processor of the electronic device (101) (e.g., processor (120) of FIG. 1) may detect a first magnetic field (e.g., a strong magnetic field) of a first external magnetic body (401) through a first Hall sensor (211) and may detect a first magnetic field of a fourth external magnetic body (407) through a second Hall sensor (213). Since a strong (or high) magnetic field is detected by both the first Hall sensor (211) and the second Hall sensor (213), the processor (120) may determine (or identify) that the external device (400) is attached in the first direction.

[0132] A second attachment example (820) may be one in which the external device (400) is attached to the electronic device (101) in a second direction. The processor (120) may detect a second magnetic field (e.g., a weak magnetic field) of the second external magnetic body (403) through the first Hall sensor (211) and may detect a first magnetic field of the first external magnetic body (401) through the second Hall sensor (213). Since the magnetic field detected by the first Hall sensor (211) is lower than the magnetic field detected by the second Hall sensor (213), the processor (120) may determine (or identify) that the external device (400) is attached in the second direction.

[0133] A third attachment example (830) may be one in which the external device (400) is attached to the electronic device (101) in a third direction. The processor (120) may detect a first magnetic field of the fourth external magnetic body (407) through the first Hall sensor (211) and detect a second magnetic field of the third external magnetic body (405) through the second Hall sensor (213). Since the magnetic field detected by the first Hall sensor (211) is higher than the magnetic field detected by the second Hall sensor (213), the processor (120) may determine (or identify) that the external device (400) is attached in the third direction.

[0134] The fourth attachment example (840) may be that the external device (400) is attached to the electronic device (101) in the fourth direction. The processor (120) may detect the second magnetic field of the third external magnetic body (405) through the first Hall sensor (211) and detect the second magnetic field of the second external magnetic body (403) through the second Hall sensor (213). Since a weak (or low) magnetic field is detected from both the first Hall sensor (211) and the second Hall sensor (213), the processor (120) may determine (or identify) that the external device (400) is attached in the fourth direction.

[0135] Accordingly, the processor (120) can identify the attached position (or attachment direction) of the external device (400) based on the magnetic field change detected by the first hall sensor (211) and the second hall sensor (213).

[0136] FIG. 8b is a diagram illustrating an example of identifying an attachment location of an external device in an electronic device according to one embodiment.

[0137] Referring to FIG. 8B, the electronic device (101) may further include two Hall sensors (e.g., the third Hall sensor (215) and the fourth Hall sensor (217) of FIG. 2A), for a total of four Hall sensors (e.g., the second embodiment (220) of FIG. 2A). In this case, the four external magnetic bodies (401 to 407) included in the external device (400) may be formed with the same magnetic field strength.

[0138] A fifth attachment example (850) may be that the external device (400) is attached to the electronic device (101) at a first attachment location (e.g., the center of the external device (400)). The processor (120) may detect a magnetic field of the first external magnetic body (401) through the first Hall sensor (211), a magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213), a magnetic field of the second external magnetic body (403) through the third Hall sensor (215), and a magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since magnetic fields are detected from all of the first Hall sensors (211) to the fourth Hall sensors (217), the processor (120) may determine (or identify) that the external device (400) is attached at the first attachment location.

[0139] The sixth attachment example (860) may be that the external device (400) is attached to the electronic device (101) at a second attachment location (e.g., left attachment of the external device (400)). The processor (120) may detect the magnetic field of the second external magnetic body (403) through the second Hall sensor (213) and may detect the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since the magnetic fields are detected by the second Hall sensor (213) and the fourth Hall sensor (217), the processor (120) may determine (or identify) that the external device (400) is attached at the second attachment location.

[0140] The seventh attachment example (870) may be that the external device (400) is attached to the electronic device (101) at a third attachment location (e.g., right attachment of the external device (400)). The processor (120) may detect the magnetic field of the third external magnetic body (405) through the first Hall sensor (211) and may detect the magnetic field of the second external magnetic body (403) through the third Hall sensor (215). Since the magnetic fields are detected by the first Hall sensor (211) and the third Hall sensor (215), the processor (120) may determine (or identify) that the external device (400) is attached at the third attachment location.

[0141] The eighth attachment example (880) may be that the external device (400) is attached to the electronic device (101) at a fourth attachment location (e.g., attached to the right side of the external device (400) downward from the electronic device (101). The processor (120) may detect the magnetic field of the third external magnetic body (405) through the third Hall sensor (215) and may detect the magnetic field of the second external magnetic body (403) through the fourth Hall sensor (217). Since the magnetic fields are detected by the third Hall sensor (215) and the fourth Hall sensor (217), the processor (120) may determine (or identify) that the external device (400) is attached at the fourth attachment location.

[0142] Accordingly, the processor (120) can identify the attachment location (or attachment location) of the external device (400) based on the magnetic field change detected by at least one of the first hall sensor (211) to the fourth hall sensor (217).

[0143] FIG. 9A is a diagram illustrating an example of executing an application when an external device is tagged in a vertical direction in an electronic device according to one embodiment.

[0144] Referring to FIG. 9A, as in the first drawing example (910), when an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1) includes four magnetic bodies (e.g., the four magnetic bodies (201 to 207) of FIG. 2A) and two Hall sensors (e.g., the first Hall sensor (211) and the second Hall sensor (213) of FIG. 2A) (e.g., the first embodiment (210) of FIG. 2A), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4A) (shaded) of an external device (e.g., the external device (400) of FIG. 4A)) may have a magnetic field strength stronger than that of the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4A).

[0145] As in the first drawing example (910) and the first attachment example (920), the electronic device (101) can be tagged (or attached) vertically with the external device (400). The processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) can detect a first magnetic field (e.g., a strong magnetic field) of the first external magnetic body (401) through the first Hall sensor (211) and can detect a first magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213). Since a strong (or high) magnetic field is detected by both the first Hall sensor (211) and the second Hall sensor (213), the processor (120) determines that the external device (400) is attached vertically and can provide the first user interface (930). The first user interface (930) may include a guide for registering the wallet with the smart tag function when the external device (400) is a smart wallet.

[0146] FIG. 9b is a diagram illustrating an example of executing an application when an external device is tagged in a horizontal direction in an electronic device according to one embodiment.

Since the magnetic field detected by the first Hall sensor (211) is lower than the magnetic field detected by the second Hall sensor (213), the processor (120) determines that the external device (400) is attached horizontally and can provide a second user interface (960). The second user interface (960) can include an execution screen of the most recently executed application when the external device (400) is a wireless charging stand.

[0149] FIG. 9c is a diagram illustrating another example of executing an application when an external device is tagged in a vertical direction in an electronic device according to one embodiment.

[0150] Referring to FIG. 9c, as in the third attachment example (970), when the electronic device (101) includes four magnetic bodies (201 to 207), a first Hall sensor (211) and a second Hall sensor (213), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4a) (shaded) of the external device (400) can be formed to have a stronger magnetic field intensity than the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4a).

[0151] As in the third attachment example (970), the electronic device (101) can be tagged (or attached) vertically with the external device (400). The processor (120) can detect the first magnetic field of the first external magnetic body (401) through the first Hall sensor (211) and the first magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213). Since a strong (or high) magnetic field is detected from both the first Hall sensor (211) and the second Hall sensor (213), the processor (120) determines that the external device (400) is attached vertically and can provide the third user interface (980). The third user interface (980) can include an execution screen of a route finding (or map) application when the external device (400) is a car cradle.

[0152] FIG. 9d is a diagram illustrating another example of executing an application when an external device is tagged in a horizontal direction in an electronic device according to an embodiment.

[0153] Referring to FIG. 9d, when the electronic device (101) includes four magnetic bodies (201 to 207), a first Hall sensor (211), and a second Hall sensor (213), as in the fourth attachment example (990), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4a) (shaded) of the external device (400) can have a magnetic field strength stronger than that of the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4a).

Since the magnetic field detected by the first Hall sensor (211) is lower than the magnetic field detected by the second Hall sensor (213), the processor (120) determines that the external device (400) is attached horizontally and can provide the fourth user interface (995). The fourth user interface (995) can include an execution screen of a music application when the external device (400) is a car cradle.

[0155] According to one embodiment, the processor (120) may collect the usage history of the electronic device (101) after attaching the external device (400), and may execute an application other than the music application by further considering the collected usage history of the electronic device (101).

[0160] Referring to FIG. 10b, when the electronic device (101) includes four magnetic bodies (201 to 207), a first Hall sensor (211), and a second Hall sensor (213), as in the second attachment example (1030), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4a) (shaded) of the external device (400) can have a magnetic field strength stronger than that of the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4a).

[0161] As in the second attachment example (1030), the electronic device (101) can be tagged (or attached) horizontally with the external device (400). The processor (120) can detect the second magnetic field of the second external magnetic body (403) through the first Hall sensor (211) and can detect the first magnetic field of the first external magnetic body (401) through the second Hall sensor (213). Since the magnetic field detected by the first Hall sensor (211) is lower than the magnetic field detected by the second Hall sensor (213), the processor (120) determines that the external device (400) is attached horizontally and can provide the second user interface (1040). The second user interface (1040) can include an execution screen of a camera application for taking pictures in a specified mode (e.g., horizontal shooting mode) (or recent shooting mode) when the external device (400) is a tripod mount. The processor (120) can activate a camera positioned on the rear of the electronic device (101) and execute a camera application to provide a second user interface (1040). The processor (120) can also provide a pop-up for taking pictures in a horizontal shooting mode using the second user interface (1040).

[0162] FIG. 10c is a diagram illustrating an example of executing an application differently depending on the attached position of an external device in an electronic device according to one embodiment.

[0163] Referring to FIG. 10c, when the electronic device (101) includes four magnetic bodies (201 to 207), a first Hall sensor (211) and a second Hall sensor (213), such as in the third attachment example (1050) or the fourth attachment example (1060), at least two magnetic bodies (e.g., the first external magnetic body (401) and the fourth external magnetic body (407) of FIG. 4a) (shaded) of the external device (400) can be formed to have a stronger magnetic field intensity than the remaining two magnetic bodies (e.g., the second external magnetic body (403) and the third external magnetic body (405) of FIG. 4a).

[0164] As in the third attachment example (1050), the electronic device (101) can be tagged (or attached) vertically with the external device (400). The processor (120) can detect the first magnetic field of the first external magnetic body (401) through the first Hall sensor (211) and can detect the first magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213). Since a strong (or high) magnetic field is detected from both the first Hall sensor (211) and the second Hall sensor (213), the processor (120) can determine that the external device (400) is attached vertically. If the external device (400) is a wireless charging stand and is attached vertically, the processor (120) can execute the first designated application.

[0165] As in the fourth attachment example (1060), the electronic device (101) can be tagged (or attached) horizontally with the external device (400). The processor (120) can detect the second magnetic field of the second external magnetic body (403) through the first Hall sensor (211) and can detect the first magnetic field of the first external magnetic body (401) through the second Hall sensor (213). Since the magnetic field detected by the first Hall sensor (211) is lower than the magnetic field detected by the second Hall sensor (213), the processor (120) can determine that the external device (400) is attached horizontally. If the external device (400) is a wireless charging stand and is attached horizontally, the processor (120) can execute the second designated application.

[0166] FIG. 11 is a flowchart (1100) illustrating a method for executing an application according to an attachment location of an external device in an electronic device according to one embodiment.

[0167] Referring to FIG. 11, in operation 1101, a processor (e.g., processor (120) of FIG. 1) of an electronic device (e.g., electronic device (101) of FIG. 1) according to an embodiment may detect and identify an external device (e.g., external device (400) of FIG. 4A). According to an embodiment, the external device (400) may include at least one of a stand including a wireless charging pad, a car cradle, a tripod mount, a lighting device, a photography filter, or an electronic pen. The external device (400) may include a plurality of external magnetic bodies (or magnet modules) (e.g., a plurality of magnetic bodies (401, 403, 405, 407) of FIG. 4A) and an NFC tag (e.g., NFC tag (409) of FIG. 4A). Alternatively, depending on the embodiment, the external device (400) may further include a wireless charging coil (e.g., wireless charging coil (419) of FIG. 4A) or at least one Hall sensor (e.g., at least one Hall sensor (411, 413) of FIG. 4A) (e.g., sensor module (176) of FIG. 1).

[0168] The electronic device (101) may include a plurality of magnetic bodies (e.g., a plurality of magnetic bodies (201 to 207) of FIG. 2A), at least one Hall sensor (e.g., a plurality of Hall sensors (211 to 217) of FIG. 2A), a wireless charging coil (e.g., a wireless charging coil (219) of FIG. 2A), and an NFC antenna (e.g., an NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) using the NFC antenna (e.g., the NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) when the NFC tag (409) of the external device (400) corresponds to the NFC antenna (209). The processor (120) may read tag information (or tag value) of the external device (400) to identify the external device (400). The tag of the external device (400) The information may be pre-stored in the external device (400). The tag information may include device information of the external device (400). The device information of the external device (400) may include the name (or identifier) ​​or type of the external device (400).

[0169] In operation 1103, the processor (120) may display information of an external device (400). The processor (120) may guide the user on a display (e.g., the display module (160) of FIG. 1) that the external device (400) is at least one of a wireless charging-enabled stand, a car cradle, a tripod mount, a lighting device, a photography filter, or an electronic pen.

[0170] In operation 1105, the processor (120) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) through the Hall sensor (213). The electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) by including two Hall sensors (211, 213) or by using four Hall sensors (211 to 217). The plurality of magnetic bodies (201 to 207) included in the electronic device (101) can be formed in a structure in which an outer S magnetic body radially wraps an inner N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). The plurality of outer magnetic bodies (401 to 407) included in the external device (400) can be formed in a structure in which an inner S magnetic body radially wraps an outer N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). Each Hall sensor can detect changes in the intensity and wavelength of a magnetic field when multiple magnetic bodies (201 to 207) are tagged to multiple external magnetic bodies (401 to 407) included in an external device (400). Each Hall sensor can transmit the detected change in the magnetic field to the processor (120). Alternatively, the processor (120) can read the change in the magnetic field detected by each Hall sensor.

[0171] In operation 1107, the processor (120) may connect an external device (400) to a low-power Bluetooth. When the external device (400) is detected, the processor (120) may connect the external device (400) to a low-power Bluetooth through a low-power Bluetooth communication module (e.g., the communication module (190) of FIG. 1). Although the drawing illustrates that operation 1107 is performed after operation 1105, operations 1105 and 1107 may be performed in parallel (e.g., simultaneously), or operation 1107 may be performed before operation 1105. This is merely an example, and the present invention is not limited by the example.

[0172] In operation 1109, the processor (120) may execute an application based on the change in the detected magnetic field. The processor (120) may identify the attached position of the external device (400) or the attachment location of the external device (400) based on the change in the detected magnetic field. The attached position (or attachment direction, tagging mode) may indicate whether the external device (400) is tagged horizontally (or horizontally) or vertically (or vertically) to the electronic device (101). Alternatively, the attachment location may indicate whether the external device (400) is tagged centrally, to the right, to the left, or downwardly to the electronic device (101).

[0173] According to one embodiment, when the electronic device (101) includes two Hall sensors (211, 213), at least two magnetic bodies (401, 407) of the external device (400) may form a magnetic field having a stronger intensity than the remaining two magnetic bodies (403, 405). Alternatively, when the electronic device (101) includes four Hall sensors (211 to 217), the processor (120) may identify the attachment location of the external device (400) based on the magnetic field changes caused by the plurality of magnetic bodies (201 to 207).

[0174] For example, if the external device (400) is a lighting device, and the processor (120) is attached to the center of the electronic device (101), it can execute a camera application in a designated mode, and if the external device (400) is attached to the right side of the electronic device (101), it can execute a camera application in a selfie mode.

[0175] In operation 1111, the processor (120) may transmit a command (or instruction) associated with the executed application to the external device (400). The processor (120) may transmit a command to the external device (400) to start wireless charging or turn on a light source via low-power Bluetooth. The external device (400) may receive the command from the electronic device (101) to start wireless charging or turn on the light source.

[0176] FIGS. 12A and 12B are diagrams illustrating an example of an application execution according to an attachment location of an external device in an electronic device according to one embodiment.

[0177] Referring to FIG. 12a, as in the first drawing example (1210), an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1) may include four magnetic bodies (e.g., four magnetic bodies (201 to 207) of FIG. 2a) and four Hall sensors (e.g., four Hall sensors (211 to 213) of FIG. 2a) (e.g., the second embodiment (220) of FIG. 2a).

[0178] The first drawing example (1210) and the first attachment example (1220) may be such that the external device (400) is attached to the electronic device (101) at a first attachment location (e.g., the center of the external device (400)). The processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may detect the magnetic field of the first external magnetic body (401) through the first Hall sensor (211), the magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213), the magnetic field of the second external magnetic body (403) through the third Hall sensor (215), and the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since a magnetic field is detected from all of the first Hall sensors (211) to the fourth Hall sensors (217), the processor (120) can determine (or identify) that the external device (400) is attached to the first attachment location. When the external device (400), which is a lighting device, is attached to the first attachment location, the processor (120) can provide a first user interface (1230). The first user interface (1230) can include an execution screen of a camera application that activates the rear camera of the electronic device (101) (e.g., a preview image of the rear camera). The processor (120) can display the first user interface (1230) on a display (e.g., the display module (160) of FIG. 1) while transmitting a command to turn on the light source to the external device (400). The external device (400) can turn on the light source based on the command received from the electronic device (101).

[0179] Referring to FIG. 12b, as in the second drawing example (1250) and the second attachment example (1260), the electronic device (101) may include four magnetic bodies (201 to 207) and four Hall sensors (211 to 213) (e.g., the second embodiment (220) of FIG. 2a).

[0180] The second drawing example (1250) and the second attachment example (1260) may be an example in which the external device (400) is attached to the electronic device (101) at a second attachment location (e.g., left attachment of the external device (400)). The processor (120) may detect the magnetic field of the second external magnetic body (403) through the second Hall sensor (213) and may detect the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since the magnetic fields are detected by the second Hall sensor (213) and the fourth Hall sensor (217), the processor (120) may determine (or identify) that the external device (400) is attached at the second attachment location. When the external device (400), which is a lighting device, is attached at the second attachment location, the processor (120) may provide a second user interface (1270). The second user interface (1270) may include an execution screen (e.g., a preview image of the front camera) of a camera application that activates the front camera of the electronic device (101) (e.g., selfie mode). The processor (120) may display the second user interface (1270) on the display module (160) while transmitting a command to turn on the light source to the external device (400). The external device (400) may turn on the light source based on the command received from the electronic device (101).

[0181] FIGS. 13a and 13b are diagrams illustrating another example of executing an application according to an attachment location of an external device in an electronic device according to one embodiment.

[0182] Referring to FIG. 13a, as in the first drawing example (1310), an electronic device according to an embodiment (e.g., electronic device (101) of FIG. 1) may include four magnetic bodies (e.g., four magnetic bodies (201 to 207) of FIG. 2a) and four Hall sensors (e.g., four Hall sensors (211 to 213) of FIG. 2a) (e.g., second embodiment (220) of FIG. 2a).

[0183] The first drawing example (1310) and the first attachment example (1320) may be such that the external device (400) is attached to the electronic device (101) at a first attachment location (e.g., the center of the external device (400)). The processor of the electronic device (101) (e.g., the processor (120) of FIG. 1) may detect the magnetic field of the first external magnetic body (401) through the first Hall sensor (211), the magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213), the magnetic field of the second external magnetic body (403) through the third Hall sensor (215), and the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since a magnetic field is detected from all of the first hall sensors (211) to the fourth hall sensors (217), the processor (120) can determine (or identify) that the external device (400) is attached to the first attachment location. When the external device (400), which is a lighting device, is attached to the first attachment location, the processor (120) can provide a first user interface (1330). The first user interface (1330) can include an execution screen of a camera application that activates the rear camera of the electronic device (101) (e.g., a preview image of the rear camera). The processor (120) can display the first user interface (1330) on a display (e.g., the display module (160) of FIG. 1) while transmitting a command to turn on the light source to the external device (400). The external device (400) can turn on the light source based on the command received from the electronic device (101).

[0184] Referring to FIG. 13b, as in the second drawing example (1350) and the second attachment example (1360), the electronic device (101) may include four magnetic bodies (201 to 207) and four Hall sensors (211 to 213) (e.g., the second embodiment (220) of FIG. 2a).

[0185] The second drawing example (1350) and the second attachment example (1360) may be an example in which the external device (400) is attached to the electronic device (101) at a second attachment location (e.g., left attachment of the external device (400)). The processor (120) may detect the magnetic field of the second external magnetic body (403) through the second Hall sensor (213) and may detect the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since the magnetic fields are detected by the second Hall sensor (213) and the fourth Hall sensor (217), the processor (120) may determine (or identify) that the external device (400) is attached at the second attachment location. When the external device (400), which is a lighting device, is attached at the second attachment location, the processor (120) may provide a second user interface (1370). The third user interface (1370) may include an execution screen (e.g., a preview image of the front camera) of a camera application that activates the front camera of the electronic device (101) (e.g., selfie mode). The processor (120) may display the second user interface (1370) on the display module (160) while transmitting a command to turn on the light source to the external device (400). The external device (400) may turn on the light source based on the command received from the electronic device (101).

[0186] FIG. 14 is a flowchart (1400) illustrating a method for executing an application according to a movement trajectory of an external device in an electronic device according to one embodiment.

[0187] Referring to FIG. 14, in operation 1401, a processor (e.g., the processor (120) of FIG. 1) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to an embodiment may detect and identify an external device (e.g., the external device (400) of FIG. 4A). According to an embodiment, the external device (400) may include at least one of a stand including a wireless charging pad, a car cradle, a tripod mount, a lighting device, a photography filter, or an electronic pen. The external device (400) may include a plurality of external magnetic bodies (or magnet modules) (e.g., the plurality of magnetic bodies (401, 403, 405, 407) of FIG. 4A) and an NFC tag (e.g., the NFC tag (409) of FIG. 4A). Alternatively, depending on the embodiment, the external device (400) may further include a wireless charging coil (e.g., wireless charging coil (419) of FIG. 4A) or at least one Hall sensor (e.g., at least one Hall sensor (411, 413) of FIG. 4A) (e.g., sensor module (176) of FIG. 1).

[0188] The electronic device (101) may include a plurality of magnetic bodies (e.g., a plurality of magnetic bodies (201 to 207) of FIG. 2A), at least one Hall sensor (e.g., a plurality of Hall sensors (211 to 217) of FIG. 2A), a wireless charging coil (e.g., a wireless charging coil (219) of FIG. 2A), and an NFC antenna (e.g., an NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) using the NFC antenna (e.g., the NFC antenna (209) of FIG. 2A). The processor (120) may detect tagging of the external device (400) when the NFC tag (409) of the external device (400) corresponds to the NFC antenna (209). The processor (120) may read tag information (or tag value) of the external device (400) to identify the external device (400). The tag of the external device (400) The information may be pre-stored in the external device (400). The tag information may include device information of the external device (400). The device information of the external device (400) may include the name (or identifier) ​​or type of the external device (400).

[0189] In operation 1403, the processor (120) may display information of an external device (400). The processor (120) may guide the user on a display (e.g., the display module (160) of FIG. 1) that the external device (400) is at least one of a wireless charging-enabled stand, a car cradle, a tripod mount, a lighting device, a photographic filter, or an electronic pen.

[0190] In operation 1405, the processor (120) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) through the Hall sensor (213). The electronic device (101) can detect the magnetic fields of the plurality of magnetic bodies (201 to 207) by including two Hall sensors (211, 213) or by using four Hall sensors (211 to 217). The plurality of magnetic bodies (201 to 207) included in the electronic device (101) can be formed in a structure in which an outer S magnetic body radially wraps an inner N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). The plurality of outer magnetic bodies (401 to 407) included in the external device (400) can be formed in a structure in which an inner S magnetic body radially wraps an outer N magnetic body so that the S magnetism is directed toward the direction of the outer device (400). Each Hall sensor can detect changes in the intensity and wavelength of a magnetic field when multiple magnetic bodies (201 to 207) are tagged to multiple external magnetic bodies (401 to 407) included in an external device (400). Each Hall sensor can transmit the detected change in the magnetic field to the processor (120). Alternatively, the processor (120) can read the change in the magnetic field detected by each Hall sensor.

[0191] In operation 1407, the processor (120) may detect a movement trajectory of the external device (101) based on a change in the detected magnetic field. For example, initially, a magnetic field may be detected from all four Hall sensors (211 to 217), but a magnetic field may be detected from only at least one of the second Hall sensor (213), the third Hall sensor (215), or the fourth Hall sensor (217).

[0192] In operation 1409, the processor (120) may execute an application based on the movement trajectory of the external device (101). For example, if the movement trajectory of the external device (101) is detected while executing a first function of the application (e.g., taking a landscape photo), the processor (120) may execute (or change) a second function of the application (e.g., selfie mode).

[0193] FIGS. 15A and 15B are drawings illustrating an example of an application execution according to a movement trajectory of an external device in an electronic device according to one embodiment.

[0194] Referring to FIG. 15A, as in the first attachment example (1510), an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1) may include four magnetic bodies (e.g., the four magnetic bodies (201 to 207) of FIG. 2A) and four Hall sensors (e.g., the four Hall sensors (211 to 213) of FIG. 2A) (e.g., the second embodiment (220) of FIG. 2A). The first attachment example (1510) may be one in which an external device (e.g., the external device (400) of FIG. 4A) is attached to the electronic device (101) at a first attachment location (e.g., the center of the external device (400)). A processor of an electronic device (101) (e.g., processor (120) of FIG. 1) can detect a magnetic field of a first external magnetic body (401) through a first Hall sensor (211), a magnetic field of a fourth external magnetic body (407) through a second Hall sensor (213), a magnetic field of a second external magnetic body (403) through a third Hall sensor (215), and a magnetic field of a third external magnetic body (405) through a fourth Hall sensor (217). Since magnetic fields are detected by all of the first Hall sensors (211) to the fourth Hall sensors (217), the processor (120) can determine (or identify) that the external device (400) is attached to the first attachment location.

[0195] Thereafter, the processor (120) can detect a first movement trajectory (1520) based on the magnetic field changes detected by the four Hall sensors (211 to 213). In the first movement trajectory (1520), the processor (120) may not detect a magnetic field from the first Hall sensor (211), the third Hall sensor (215), and the fourth Hall sensor (1217), and may detect the magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213). Alternatively, the processor (120) may detect a stronger magnetic field from the second Hall sensor (213) than from the first Hall sensor (211), the third Hall sensor (215), and the fourth Hall sensor (1217). In this case, the processor (120) can detect a movement trajectory change (1521) centered on the fourth external magnetic body (407) of the external device (400).

[0196] Subsequently, the processor (120) can detect a second movement trajectory (1530) based on the magnetic field changes detected by the four Hall sensors (211 to 213). In the second movement trajectory (1530), the processor (120) may not detect a magnetic field from the first Hall sensor (211), the third Hall sensor (215), and the fourth Hall sensor (1217), and may detect a magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213). Alternatively, the processor (120) may detect a stronger magnetic field from the second Hall sensor (213) than from the first Hall sensor (211), the third Hall sensor (215), and the fourth Hall sensor (1217).

[0197] Moving on, the external device (400) can be attached to the electronic device (101) at a second attachment location (e.g., left attachment of the external device (400)), as in the second attachment example (1540). The processor (120) can detect the magnetic field of the second external magnetic body (403) through the second Hall sensor (213) and can detect the magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since the magnetic fields are detected by the second Hall sensor (213) and the fourth Hall sensor (217), the processor (120) can determine (or identify) that the external device (400) is attached at the second attachment location. When the external device (400), which is a lighting device, is attached at the second attachment location, the processor (120) can execute a second function of the application (e.g., selfie mode). The processor (120) may display a first execution screen of the camera application (e.g., a preview image of a rear camera) in the first attachment example (1510), and then display a second execution screen of the camera application (e.g., a preview image of a front camera) in the second attachment example (1540).

[0198] Referring to FIG. 15B, a third attachment example (1550) may be one in which the external device (400) is attached to the electronic device (101) at a first attachment location (e.g., the center of the external device (400)). The processor (120) may detect a magnetic field of the first external magnetic body (401) through the first Hall sensor (211), a magnetic field of the fourth external magnetic body (407) through the second Hall sensor (213), a magnetic field of the second external magnetic body (403) through the third Hall sensor (215), and a magnetic field of the third external magnetic body (405) through the fourth Hall sensor (217). Since magnetic fields are detected from all of the first Hall sensors (211) to the fourth Hall sensors (217), the processor (120) may determine (or identify) that the external device (400) is attached at the first attachment location.

[0199] Thereafter, the processor (120) can detect the movement trajectory of the external device (400) based on the magnetic field changes detected by the four Hall sensors (211 to 213). The processor (120) can detect that the external device (400) is attached to the electronic device (101) at the second attachment location (1570) based on the movement trajectory of the external device (400).

[0200] The processor (120) can execute the second function (1580) of the application when the external device (400) is attached to the second attachment location (1570). For example, the external device (400) can be a lighting device, a speaker, a microphone for photography, or a front recognition sensor. The processor (120) can display the first execution screen of the camera application (e.g., a preview image of the rear camera) in the third attachment example (1550), and then display the second execution screen of the camera application (e.g., a preview image of the front camera) in the fourth attachment example (1580).

[0201] Fig. 16 is a flowchart illustrating an operation method of an external device according to one embodiment.

[0202] Referring to FIG. 16, in operation 1601, a processor (e.g., a processor (120) of FIG. 1) of an external device (e.g., an external device (400) of FIG. 4A) according to an embodiment may detect and identify an electronic device (101). According to an embodiment, the external device (400) may include at least one of a stand including a wireless charging pad, a car cradle, a tripod mount, a lighting device, a photographic filter, or an electronic pen. The external device (400) may include a plurality of external magnetic bodies (or magnet modules) (e.g., a plurality of magnetic bodies (401, 403, 405, 407) of FIG. 4A), at least one Hall sensor (e.g., at least one Hall sensor (411, 413) of FIG. 4A) (e.g., a sensor module (176) of FIG. 1), and an NFC tag (e.g., an NFC tag (409) of FIG. 4A). In 16, the electronic device (101) may include a plurality of magnetic bodies (e.g., a plurality of magnetic bodies (201 to 207) of FIG. 2A), a wireless charging coil (e.g., a wireless charging coil (219) of FIG. 2A), and an NFC antenna (e.g., an NFC antenna (209) of FIG. 2A). That is, in the embodiment of FIG. 16, the electronic device (101) may not detect the tagging of the external device (400), and the external device (400) may detect the tagging of the electronic device (101). In this case, the electronic device (101) may not include a Hall sensor.

[0203] In operation 1603, the processor (120) can detect the magnetic fields of the plurality of magnetic bodies (401, 403, 405, 407) through at least one Hall sensor. The plurality of magnetic bodies (201 to 207) included in the electronic device (101) can be formed in a structure in which an outer S magnetic body radially wraps around an inner N magnetic body so that the S magnetism is directed toward the direction of the magnetic body. The plurality of outer magnetic bodies (401 to 407) included in the external device (400) can be formed in a structure in which an inner S magnetic body radially wraps around an outer N magnetic body so that the S magnetism is directed toward the direction of the magnetic body. Each Hall sensor can detect a change in the intensity and wavelength of the magnetic field when the plurality of magnetic bodies (201 to 207) are tagged to the plurality of outer magnetic bodies (401 to 407) included in the external device (400). Each Hall sensor can transmit the change in the detected magnetic field to the processor (120). Alternatively, the processor (120) can read the change in the magnetic field detected by each Hall sensor.

[0204] In operation 1605, the processor (120) may connect an external device (400) to a low-power Bluetooth. When an electronic device (101) is detected, the processor (120) may connect an external device (400) to a low-power Bluetooth through a low-power Bluetooth communication module (e.g., the communication module (190) of FIG. 1). Although the drawing illustrates that operation 1605 is performed after operation 1603, operations 1603 and 1605 may be performed in parallel (e.g., simultaneously), or operation 1605 may be performed before operation 1603. This is merely an example, and the present invention is not limited by the example.

[0205] In operation 1607, the processor (120) can transmit the change value of the detected magnetic field. In the embodiment of FIG. 16, the electronic device (101) does not detect the tagging of the external device (400), and since the external device (400) detects the tagging of the electronic device (101), the external device (400) can transmit the change value of the magnetic field to the electronic device (101). The processor (120) can transmit the change value of the detected magnetic field to the electronic device (101) via the low-power Bluetooth.

[0206] In operation 1609, the processor (120) may receive a command from the electronic device (101). The electronic device (101) may identify the attached position of the external device (400) or the attachment location of the external device (400) based on the change value of the magnetic field received from the external device (400). For example, if the external device (400) is a lighting device and the external device (400) is attached to the center of the electronic device (101), the electronic device (101) may execute a camera application in a designated mode, and if the external device (400) is attached to the right side of the electronic device (101), the camera application in a selfie mode may be executed. The electronic device (101) may transmit a command associated with the executed application to the external device (400).

[0207] In operation 1611, the processor (120) may perform an operation based on the received command. The processor (120) may start wireless charging or turn on a light source based on the command received from the electronic device (101).

Based on changes in the magnetic fields of the plurality of magnetic bodies (201 to 207), the processor (120) can identify that the external device (400) is attached to the first attachment location (1710, 1720) which is the center of the electronic device (101). Additionally, the processor (120) can identify that the external device (400) is attached to a second attachment location (1730) (e.g., the right side of the electronic device (101)) which is a side of the electronic device (101) or a third attachment location (1740) (e.g., the right side of the electronic device (101)) which is another side of the electronic device (101) based on changes in the magnetic fields of the plurality of magnetic bodies (201 to 207).

[0211] Referring to FIG. 17B, the processor (120) can identify that an external device (400) is attached in a horizontal direction (1750) based on changes in the magnetic fields of a plurality of magnetic bodies (201 to 207).

[0214] Referring to FIG. 17d, as in the first movement trajectory example (1790), the processor (120) can detect the movement trajectory of a square-shaped external device (400) based on the magnetic field changes of the plurality of magnetic bodies (201 to 207). Alternatively, as in the second movement trajectory example (1595), the processor (120) can detect the movement trajectory of a rectangular-shaped external device (400) based on the magnetic field changes of the plurality of magnetic bodies (201 to 207).
