[0070] FIG. 4A illustrates a perspective view of an exemplary electronic device according to one embodiment.

[0071] Referring to FIG. 4A, an electronic device (400) (e.g., the electronic device (101) of FIG. 1) may include a housing (401) that includes a first side (411) facing a part of a user's body (e.g., a finger) and a second side (412) opposite the first side (411). For example, the electronic device (400) may include a ring-shaped housing (401). As an example, the electronic device (400) may be configured in a ring shape.

[0072] According to one embodiment, the electronic device (400) may be referred to as a wearable device that can be worn by a user. The electronic device (400) may be worn on a part of the user's body (e.g., a finger). For example, the electronic device (400) may be fastened to a part of the user's body. For example, the electronic device (400) may be detachable from a part of the user's body. For example, the electronic device (400) 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.

[0073] For example, the electronic device (400) may be worn by the user and thus come into contact with a part of the user's body. For example, the electronic device (400) may be configured to obtain information about the user through a part of the user's body by being worn by the user. As an example, the information about the user may include the user's health information. However, the present invention is not limited thereto. For example, the electronic device (400) may provide information about the user through the electronic device (400) and / or an external electronic device connected to the electronic device (400). However, the present invention is not limited thereto.

[0074] According to one embodiment, at least a portion of the first surface (411) may come into contact with a part of the user's body when the electronic device (400) is worn by the user. For example, the first surface (411) may surround a part of the user's body on which the electronic device (400) is worn. For example, the first surface (411) may cover a part of the user's body on which the electronic device (400) is worn. For example, the first surface (411) may be configured to pressurize or provide pressure to a part of the user's body when the electronic device (400) is worn by the user, thereby allowing the electronic device (400) to be fastened to the part of the body. For example, the first surface (411) may be deformable by a part of the user's body. For example, the electronic device (400) can provide information about the user through the first side (411) based on haptic technology.

[0075] For example, the second surface (412) may form an outer appearance of the electronic device (400) together with the first surface (411). For example, the second surface (412) may form a ring-shaped housing (401) together with the first surface (411). For example, the second surface (412) may be a surface spaced apart from a part of the user's body when the electronic device (400) is worn by the user. For example, the first surface (411) may be referred to as an inner circumference surface of the housing (401). The second surface (412) opposite to the first surface (411) may be referred to as an outer circumference surface of the housing (401).

[0076] For example, the second side (412) may be exposed to the outside when the electronic device (400) is worn by the user. The second side (412) may be composed of at least one of titanium, stainless steel, and ceramic. The second side (412) may be composed of a material for protection against external impact and / or scratches. Depending on the embodiment, the second side (412) may be coated with an additional material for protection of the color and / or the appearance of the electronic device (400).

[0077] For example, the first side (411) may be composed of the same and / or similar material as the second side (412). In some embodiments, at least a portion of the first side (411) may be composed of at least one of a molding material for acquiring data, transparent plastic, and / or glass. In some embodiments, at least a portion of the first side (411) may be composed of a metal for identifying a biosignal.

[0078] According to one embodiment, the electronic device (400) may further include a hole (470) formed by the first surface (411) for passing a part of the user's body through the electronic device (400) when the user wears the electronic device. For example, the hole (470) may be penetrated by a part of the user's body when the user wears the electronic device (400). By including the hole (470) configured to pass a part of the user's body through the hole, the electronic device (400) may be configured to be fastened to a part of the user's body when the user wears the electronic device (400).

[0079] According to one embodiment, the electronic device (400) may further include one or more components between the first side (411) and the second side (412). For example, the electronic device (400) may include a communication circuit, one or more sensors, and / or a processor between the first side (411) and the second side (412). The arrangement of the one or more components will be described later in FIG. 4B.

[0080] FIG. 4b is an example of a partial cross-sectional view of an electronic device according to one embodiment.

[0081] Referring to FIG. 4B, the electronic device (400) may be formed in a ring shape. For example, the housing (401) of the electronic device (400) may be formed in a ring shape that can be worn on a user's finger. In FIGS. 4A and 4B, an electronic device (400) having a ring shape with a smooth surface is illustrated as an example, but the present invention is not limited thereto. For example, the electronic device (400) may be implemented as a housing including a plurality of flat surfaces. For example, an electronic device (400) having a ring shape with an unsmooth surface may also be understood as an embodiment of the present disclosure.

[0082] According to one embodiment, the ring-shaped housing (401) may include a first side (411) that comes into contact with the user's body when worn by the user, a second side (412) that is exposed to the outside, and a side surface between the first side (411) and the second side (412). For example, the first side (411) and the second side (412) may include a space for including (or arranging) at least one or more components (e.g., a processor (410), a communication circuit (420), a sensor (430), and a memory (440)).

[0083] According to one embodiment, a PCB (451) may be disposed between a first side (411) and a second side (412) of an electronic device (400). For example, a processor (410), a communication circuit (420), an acceleration sensor (431), a gyro sensor (432), a photoplethysmography (PPG) sensor (433), a temperature sensor (434), a memory (440), and / or a PMIC (454) may be disposed on the PCB (451). For example, the PCB (451) may be composed of a rigid region and a flexible region. As an example, the rigid region may be referred to as a rigid flexible printed circuit board (RFPCB). As an example, the flexible region may be referred to as a flexible printed circuit board (FPCB).

[0084] For example, the PPG sensor (433) may include one or more light-emitting circuits (433-1), one or more light-receiving circuits (433-2), and a control circuit (433-3). As an example, the one or more light-emitting circuits (433-1) and the one or more light-receiving circuits (433-2) may be arranged toward the first side (411). As an example, the control circuit (433-3) may be arranged toward the second side (412).

[0085] For example, the PMIC (454) can be used to manage power of the electronic device (400). The PMIC (454) can be used to provide (or distribute) power to components that require power in the electronic device (400). The PMIC (454) can support a wired charging method (e.g., terminal, pogo pin) or a wireless charging method (e.g., wireless power consortium (WPC), NFC) for charging the electronic device (400) through the charging interface (453).

[0086] According to one embodiment, a battery (452) may be disposed between the first side (411) and the second side (412) of the electronic device (400). The battery (452) may be configured with at least one battery (or battery pack). For example, the battery (452) may be configured such that at least one battery is connected in series and / or in parallel. For example, the battery (452) may be configured as a flexible battery pack. For example, the battery (452) may be charged and / or discharged as a secondary battery. For example, the material constituting the battery (452) may be configured in various ways. For example, the material constituting the battery (452) may include at least one of lithium ion and mercury.

[0087] According to one embodiment, an antenna (455) may be disposed between the first side (411) and the second side (412) of the electronic device (400). For example, the antenna (455) may be composed of a single antenna and / or a plurality of segmented antennas. According to an embodiment, the antenna (455) may be composed of a part of the housing (401) of the electronic device (400). For example, the antenna (455) may be electrically connected to the communication circuit (420) via the PCB (451).

[0088] Although not illustrated, the electronic device (400) may include various other components in addition to the illustrated components. For example, the electronic device (400) may include a display. The display may be positioned on the outer surface of the housing (401).

[0089] According to one embodiment, a first wearable device (e.g., electronic device 200 of FIG. 2 or electronic device 300 of FIG. 3) and a second wearable device (e.g., electronic device 400 of FIGS. 4A and 4B) may be worn by a user and operated. For example, the first wearable device may be worn on a first part of the user's body (e.g., wrist). The second wearable device may be worn on a second part of the user's body (e.g., finger). The second wearable device may be configured in a ring shape. The second wearable device may be operated while being positioned at a designated location and / or in a designated direction on the second part of the user's body. However, since the second wearable device is configured in a ring shape, it may rotate on the second part of the user's body. If the second wearable device is rotated on the second part of the user's body, data acquired through at least one sensor included in the second wearable device may be inaccurate. Therefore, a method for identifying whether the second wearable device has been rotated may be required.

[0090] The first wearable device (or the electronic device connected to the first wearable device and the second wearable device) can identify whether the second wearable device is rotated based on information about the orientation of the first wearable device and information about the orientation of the second wearable device, and guide the second wearable device to be placed at a designated location and / or in a designated direction on a second part of the user's body.

[0091] The operation of the first wearable device (or the electronic device connected to the first wearable device and the second wearable device) according to the above-described embodiment may be described below. The first wearable device described below may correspond to the electronic device (200) of FIGS. 2A and 2B and / or the electronic device (300) of FIG. 3. The second wearable device described below may correspond to the electronic device (400) of FIGS. 4A and 4B.

[0092] FIG. 5 illustrates an example of an environment including a first wearable device and a second wearable device, according to one embodiment.

[0093] Referring to FIG. 5, the first wearable device (510) and the second wearable device (520) can operate while being worn by a user. The first wearable device (510) can be worn on a first part of the user's body (e.g., a wrist). The second wearable device (520) can be worn on a second part of the user's body (e.g., a finger).

[0094] For example, the first wearable device (510) and the second wearable device (520) may be worn on the same arm of the user. As an example, the first wearable device (510) and the second wearable device (520) may be worn on the user's left arm. The first wearable device (510) may be worn on the wrist of the left arm, and the second wearable device (520) may be worn on one of the fingers of the left arm. As an example, the first wearable device (510) and the second wearable device (520) may be worn on the user's right arm. The first wearable device (510) may be worn on the wrist of the right arm, and the second wearable device (520) may be worn on one of the fingers of the right arm.

[0095] According to one embodiment, the first wearable device (510) may correspond to the electronic device (200) of FIGS. 2A and 2B or the electronic device (300) of FIG. 3. The second wearable device (520) may correspond to the electronic device (400) of FIGS. 4A and 4B.

[0096] For example, the first wearable device (510) may be configured in a watch shape. The second wearable device (520) may be configured in a ring shape. When the second wearable device (520) is configured in a ring shape, it can be rotated on the user's finger. Since at least one sensor of the second wearable device (520) is arranged as shown in FIG. 4B, the second wearable device (520) can operate when at least one sensor of the second wearable device (520) is arranged toward the user's palm. When the second wearable device (520) is rotated on the user's finger, at least one sensor may not be arranged toward the user's palm. When at least one sensor is not arranged toward the user's palm, information (or data) acquired through the at least one sensor may not be accurate.

[0097] For example, a state in which at least one sensor is positioned toward the user's palm may be referred to as a normal wearing state. A state in which the angle between the direction in which a designated portion of the second wearable device (520) (e.g., the portion in which at least one sensor is positioned) is facing and the direction in which the palm is facing is within a designated range may be referred to as a normal wearing state. For example, even if one of the sensors of the second wearable device (520) is not positioned directly toward the user's palm, if the angle between the direction in which a designated portion of the second wearable device (520) (e.g., the portion in which at least one sensor is positioned) is facing and the direction in which the palm is facing is within a predefined designated range (or tolerance), the second wearable device (520) is still in a normal wearing state. A state in which at least one sensor is not positioned toward the user's palm may be referred to as an abnormal wearing state. If the angle between the direction in which a designated portion of the second wearable device (520) (e.g., a portion in which at least one sensor is placed) is facing and the direction in which the palm is facing is outside a predefined range (or tolerance), the second wearable device (520) may be in an abnormal wearing state.

[0098] For example, the second wearable device (520) may include affordances (e.g., grooves, electrodes, displays, or indicators) on the exterior of the second wearable device (520) to guide a normal wearing state. A user of the second wearable device (520) may position (or align) the second wearable device (520) to operate in the normal wearing state through the affordances. For example, a user of the second wearable device (520) may position and / or reposition the second wearable device (520) on a body part (e.g., a finger) to align (fit and / or touch) the electrodes, display, and / or indicators so that the second wearable device (520) operates in the normal wearing state.

[0099] According to one embodiment, the first wearable device (510) may be connected to the second wearable device (520). For example, the user of the first wearable device (200) and the user of the second wearable device (520) may be the same. The first wearable device (510) and the second wearable device (520) may be owned (or used) by the same user.

[0100] For example, the second wearable device (520) may be a device that is connected to the first wearable device (510) at a close range and used (simultaneously) by the same user. The second wearable device (520) may be used to control the operation of the first wearable device (510). The second wearable device (520) may be used to receive information acquired through the first wearable device (510) and process the received information. The first wearable device (510) may control the second wearable device (520). The user may change the setting information of the second wearable device (520) using the first wearable device (510).

[0101] According to one embodiment, the first wearable device (510) may identify that the second wearable device (520) is operating in an abnormal wearing state based on information received from the second wearable device (520). The first wearable device (510) may provide a notification to guide changing at least one of the position or orientation of the second wearable device (520) so that the second wearable device (520) can operate in a normal wearing state. Specific operations for the first wearable device (510) to perform the above-described operation will be described later with reference to FIGS. 7 to 16.

[0102] According to an embodiment, the first wearable device (510) and the second wearable device (520) may be controlled by an external electronic device. The external electronic device may use information obtained from the first wearable device (510) and / or information obtained from the second wearable device (520) to identify that the second wearable device (520) is operating in an abnormal wearing state. The external electronic device may provide a notification to guide changing at least one of the position or orientation of the second wearable device (520) so that the second wearable device (520) can operate in a normal wearing state. A specific example in which the first wearable device (510) and the second wearable device (520) are controlled by an external electronic device will be described later with reference to FIGS. 17A and 17B.

[0103] FIG. 6 is a simplified block diagram of a first wearable device and a second wearable device according to one embodiment.

[0104] Referring to FIG. 6, the first wearable device (510) and the second wearable device (520) can operate in a connected state. For example, the first wearable device (510) and the second wearable device (520) can be used to obtain (or identify) information about a user. The first wearable device (510) can be used to control the second wearable device (520).

[0105] According to one embodiment, the first wearable device (510) may include a processor (511), a communication circuit (512), a sensor (513), a memory (514), and / or a display (515). Depending on the embodiment, the first wearable device (510) may include at least one of the processor (511), the communication circuit (512), the sensor (513), the memory (514), and / or the display (515). For example, at least some of the processor (511), the communication circuit (512), the sensor (513), the memory (514), and / or the display (515) may be omitted depending on the embodiment.

[0106] According to one embodiment, the processor (511) may correspond to the processor (120) of FIG. 1. The processor (511) may be operatively or operably coupled with or connected to the communication circuit (512), the sensor (513), the memory (514), and the display (515). The processor (511) being operatively or operably coupled with the communication circuit (512), the sensor (513), the memory (514), and the display (515) may mean that the processor (511) can control the communication circuit (512), the sensor (513), the memory (514), and the display (515). For example, the communication circuit (512), the sensor (513), the memory (514), and the display (515) may be controlled by the processor (511).

[0107] Although illustrated based on different blocks, the embodiment is not limited thereto, and some of the hardware of FIG. 3 (e.g., at least a portion of the processor (511), the communication circuit (512), and the memory (514)) may be included in a single integrated circuit such as a system on a chip (SoC).

[0108] According to one embodiment, the processor (511) may be configured with at least one processor. For example, the processor (511) may be configured with a main processor that performs high-performance processing and a secondary processor that performs low-power processing. At least some of the sensors (513) may be connected to the secondary processor. At least some of the sensors connected to the secondary processor may acquire data about the user for 24 hours. 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 first wearable device (510). For example, the secondary processor may be activated when the battery of the first wearable device (510) is low. For example, the main processor may be activated when more accurate data about the user is required.

[0109] According to one embodiment, the processor (511) may include a hardware component for processing data based on one or more instructions. The hardware component for processing data may include, for example, an arithmetic and logic unit (ALU), a field programmable gate array (FPGA), and / or a central processing unit (CPU).

[0110] For example, the processor (511) may include an application processor, a supplementary processor (e.g., a sensor hub, a microcontroller unit (MCU)), a central processor unit (CPU), a neural processing unit (NPU), a graphic processing unit (GPU), and / or a processor for IoT (e.g., a processor integrated with a communication module).

[0111] According to one embodiment, the processor (511) can determine the operating time of the sensor (513). The processor (511) can control the operation of the sensor (513). The processor (511) can process information obtained from the sensor (513).

[0112] According to one embodiment, the first wearable device (510) may include a communication circuit (512). The communication circuit (512) may correspond to at least a portion of the communication module (190) of FIG. 1.

For example, the communication circuit (512) may be used to perform Bluetooth communication, wireless local area network (WLAN) communication, Zigbee communication, near field communication (NFC), ultra wide band (UWB) communication, radio-frequency identification (RFID) communication, or ANT+ communication. For example, the communication circuit (512) may be used to perform cellular communication. For example, the processor (511) may establish a connection with another electronic device (e.g., the second wearable device (520)) through the communication circuit (512). For example, the processor (511) may identify (or measure) the location of the first wearable device (510) based on a wireless signal (e.g., a global positioning system (GPS) signal) received or transmitted by the communication circuit (512). In some embodiments, the communication circuit (512) may be configured to be integrated with the processor (511).

[0113] According to one embodiment, the first wearable device (510) may include a sensor (513). The sensor (513) may be used to obtain various information.

For example, the sensor (513) may be composed of at least one sensor. For example, the sensor (513) may correspond to the sensor module (176) of FIG. 1.

[0114] For example, the sensor (513) may include an acceleration sensor (513-1). The acceleration sensor (513-1) may be used to identify a change in acceleration of the first wearable device (510). As an example, the acceleration sensor (513-1) may identify (or measure, detect) acceleration of the first wearable device (510) in three directions including the x-axis, the y-axis, and the z-axis. As an example, the acceleration sensor (513-1) may be configured to identify acceleration that is about four times or more the acceleration of gravity in any axis. As an example, the acceleration sensor (513-1) may have a resolution of a specified size (e.g., 16 bits).

[0115] For example, the sensor (513) may include a gyro sensor (513-2). The gyro sensor (513-2) may identify (or measure, detect) the angular velocity of the first wearable device (510) in three directions including the x-axis, the y-axis, and the z-axis. According to an embodiment, the first wearable device (510) may include an inertial sensor including an acceleration sensor (513-1) and a gyro sensor (513-2).

[0116] For example, the first wearable device (510) may use at least one of an acceleration sensor (513-1) and / or a gyro sensor (513-2) to identify at least one of data regarding movement of the first wearable device (510), data regarding a user's gesture, data regarding an amount of impact, data regarding an orientation of the first wearable device (510), and / or activity information of the user (e.g., sitting, moving, sports activity, etc.).

[0117] For example, the sensor (513) may include a photoplethysmography (PPG) sensor (513-3). The PPG sensor (513-3) may be used to measure pulse (or a change in blood volume within a blood vessel) by identifying a change in light sensitivity according to a change in blood vessel volume. The PPG sensor (513-3) may include one or more photodiodes (PDs) and one or more light emitting diodes (LEDs). For example, the PPG sensor (513-3) may be used to identify a change in blood flow within a blood vessel during a heartbeat. The PPG sensor (513-3) may identify a change in blood flow within a blood vessel during a heartbeat when the light sensor is in contact with the skin over a peripheral blood vessel. The processor (511) may identify blood flow and a change in blood flow based on the PPG signal and waveform.

[0118] For example, the PPG sensor (513-3) may include a transmissive PPG sensor and / or a reflective PPG sensor.

[0119] For example, the PPG sensor (513-3) 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 (513-3) 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 (513-3) can store the identified value in the memory (514) (or buffer) via an ADC (analog to digital converter) based on the reflected and / or transmitted light.

[0120] 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, green light, which is complementary to blood, can be used as the LED.

[0121] For example, the sensor (513) may include a temperature sensor (513-4). The temperature sensor (513-4) may be used to identify (or measure) the skin temperature of a part of the user's body (e.g., the wrist). For example, the temperature sensor (513-4) may include a contact temperature sensor and a non-contact temperature sensor. The identified temperature value may be stored in the memory (514) or transmitted to the processor (511). The processor (511) may identify (or estimate) the user's condition, the environment in which the user is located, and / or the user's body temperature based on the identified temperature value.

[0122] Although not shown, the sensor (513) may further include various sensors for obtaining (or identifying, measuring, detecting) various data about the user and / or the first wearable device (510).

[0123] According to one embodiment, the first wearable device (510) may include a memory (514). The memory (514) may be used to store information or data. For example, the memory (514) may be used to store data obtained from a user. For example, the memory (514) may correspond to the memory (130) of FIG. 1. For example, the memory (514) may be a volatile memory unit or units. For example, the memory (514) may be a non-volatile memory unit or units. As another example, the memory (514) may be another form of computer-readable media, such as a magnetic or optical disk. For example, the memory (514) may store data obtained based on operations performed by the processor (511) (e.g., algorithm execution operations). For example, the memory (514) may store data obtained from a sensor (513) (e.g., information about the user). According to an embodiment, the memory (514) may be configured in an integrated form with the processor (511).

[0124] Although not illustrated in FIG. 6, the first wearable device (510) may further include various components. For example, the first wearable device (510) may further include at least one of an antenna, a power management integrated circuit (PMIC), a battery, and a flexible printed circuit board (FPCB). According to an embodiment, the first wearable device (510) may further include a biometric sensor (e.g., an electrocardiogram (ECG) sensor) including a PPG sensor (513-3).

[0125] According to one embodiment, the first wearable device (510) may include a display (515). The display (515) may output visualized information to the user. For example, the display (515) may be controlled by a processor (511) including a circuit such as a graphic processing unit (GPU) to output visualized information to the user. For example, the display (515) may correspond to the display module (160) of FIG. 1.

[0126] For example, the display (515) may be used to display a screen for displaying information about the user. For example, the display (515) may be used to provide notifications to guide the user's posture. For example, the display (515) may be used to provide notifications to guide a change in at least one of the position or orientation of the second wearable device (520).

[0127] According to an embodiment, the second wearable device (520) may include a processor (521), a communication circuit (522), a sensor (523), and / or a memory (524). According to an embodiment, the second wearable device (520) may include at least one of the processor (521), the communication circuit (522), the sensor (523), and / or the memory (524). For example, at least some of the processor (521), the communication circuit (522), the sensor (523), and / or the memory (524) may be omitted according to an embodiment. For example, the second wearable device (520) may correspond to the electronic device (101) of FIG. 1. For example, the second wearable device (520) may include at least some of the components of the electronic device (101) of FIG. 1.

[0128] For example, the processor (521) may correspond to the processor (511) of the first wearable device (510). For example, the communication circuit (522) may correspond to the communication circuit (512) of the first wearable device (510). For example, the memory (524) may correspond to the memory (514) of the first wearable device (510).

[0129] According to one embodiment, the sensor (523) can be used to obtain various information. For example, the sensor (523) can correspond to the sensor (513) of the first wearable device (510). The sensor (523) can include at least one of an acceleration sensor (523-1), a gyro sensor (523-2), a PPG sensor (523-3), and / or a temperature sensor (523-4). According to an embodiment, the sensor (523) can obtain information that is distinct from the information obtained by the sensor (513) of the first wearable device (510). For example, the sensor (523) can be used to identify (or measure) data about the user from a second part of the user's body (e.g., a finger).

[0130] According to one embodiment, the second wearable device (520) may further include various components in addition to the illustrated components. According to one embodiment, the second wearable device (520) may further include a display.

[0131] Figure 7 illustrates a flowchart of the operations of a first wearable device according to one embodiment. In the following embodiments, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0132] In operation 710, the processor (511) of the first wearable device (510) may obtain first information regarding the orientation of the first wearable device (510) worn on a first part of the user's body. For example, the processor (511) may obtain first information regarding the orientation of the first wearable device (510) worn on the first part of the user's body using a sensor (513) (e.g., an acceleration sensor (513-1) or a gyro sensor (513-2)).

[0133] For example, the first information may include a first rotation angle of the first wearable device (510) along a specified axis. For example, the specified axis may be set to a direction in which a finger faces when the first wearable device (510) is worn on the user's wrist. The processor (511) may identify the first rotation angle based on whether the first wearable device (510) is rotated clockwise (or counterclockwise) with respect to the specified axis. For example, the processor (511) may identify the first rotation angle based on a direction in which a display (515) of the first wearable device (510) faces and a direction in which the specified axis faces. The first rotation angle may refer to an angle by which the first wearable device (510) is rotated according to the rotation of the user's forearm bone (or wrist). For example, a specific operation for identifying the first rotation angle will be described later in Fig. 8a.

[0134] In operation 720, the processor (511) may receive second information regarding the orientation of the second wearable device (520) from the second wearable device (520) worn on a second part of the user's body. For example, the processor (521) of the second wearable device (520) may obtain second information regarding the orientation of the second wearable device (520) worn on the second part of the user's body using a sensor (523) (e.g., an acceleration sensor (523-1) or a gyro sensor (523-2)). The processor (521) of the second wearable device (520) may transmit the second information regarding the orientation of the second wearable device (520) to the first wearable device (510). The processor (511) of the first wearable device (510) can identify the second information based on receiving second information about the orientation of the second wearable device (520) from the second wearable device (520).

[0135] For example, the second information may include a second rotation angle of the second wearable device (520) along a specified axis. For example, the specified axis may be set to correspond to a direction perpendicular to a plane corresponding to a hole of the second wearable device (520). For example, the specified axis may be set to a direction in which a finger of a user faces when the second wearable device (520) is worn on the user's finger. The second wearable device (520) (or the processor (521) of the second wearable device (520)) may identify the second rotation angle based on whether the second wearable device (520) is rotated clockwise (or counterclockwise) with respect to the specified axis. For example, the second wearable device (520) (or the processor (521) of the second wearable device (520)) can identify the second rotation angle based on the direction in which a designated portion of the second wearable device (520) is facing and the direction in which the designated axis is facing.

[0136] According to one embodiment, the second rotation angle may be identified based on a movement of the user (e.g., rotation of the forearm bone (or wrist)) or a rotation of the second wearable device (520) relative to a second part of the user's body (e.g., a finger). For example, a specific operation for identifying the second rotation angle will be described below in FIG. 8B.

[0137] According to one embodiment, the processor (511) may synchronize an axis (hereinafter, referred to as the first axis) for identifying a first rotation angle in the first wearable device (510) and an axis (hereinafter, referred to as the second axis) for identifying a second rotation angle in the second wearable device (520). For example, the first axis for identifying the first rotation angle in the first wearable device (510) may be set to a direction in which a finger is facing when the first wearable device (510) is worn on the user's wrist. The second axis for identifying the second rotation angle in the second wearable device (520) may be set to correspond to a direction perpendicular to a plane corresponding to a hole in the second wearable device (520). The processor (511) may perform an operation for setting the first axis and the second axis to be substantially identical. For example, the processor (511) may perform an operation to set the first axis and the second axis to be substantially the same before acquiring the first information and receiving the second information. The operation of the processor (511) to set the first axis and the second axis to be substantially the same will be described later in FIG. 15.

[0138] In operation 730, the processor (511) may provide a notification to guide changing at least one of the position or direction of the second wearable device (520) on the second part of the user's body. For example, the processor (511) may provide a notification to guide changing at least one of the position or direction of the second wearable device (520) on the second part of the user's body (e.g., a finger) based on the first information and the second information.

[0139] According to one embodiment, the processor (511) can identify a posture of the second wearable device (520) based on the first information and the second information. The processor (511) can identify a position of the second wearable device (520) with respect to the first wearable device (510) based on the first information and the second information. The processor (511) can identify a rotation angle of the second wearable device (520) with respect to the first wearable device (510) based on the first information and the second information. The processor (511) can identify a positional relationship between the first wearable device (510) and the second wearable device (520) based on the first information and the second information.

[0140] According to one embodiment, the processor (511) may identify whether a difference between the first rotation angle and the second rotation angle is outside a specified range based on the first information and the second information. Based on the difference between the first rotation angle and the second rotation angle being outside the specified range, the processor (511) may identify that the second wearable device (520) has been rotated on a second part of the user's body. Based on identifying that the second wearable device (520) has been rotated on the second part of the user's body, the processor (511) may identify a wearing state of the second wearable device (520) as an abnormal wearing state. For example, a normal wearing state may mean a state in which an angle between a direction in which a specified part of the second wearable device (e.g., a part in which at least one sensor is arranged) faces and a direction in which a palm faces is within a specified range. For example, an abnormal wearing state may mean a state in which the angle between the direction in which a designated part of the second wearable device (520) (e.g., a part in which at least one sensor is placed) is facing and the direction in which the palm is facing is outside a designated range.

[0141] According to one embodiment, the processor (511) may provide a notification to guide the user to change the wearing state of the second wearable device (520) from an abnormal wearing state to a normal wearing state based on the first information and the second information. Accordingly, the notification for the first wearable device (510) guides the user to change the wearing state of the second wearable device (520) from an abnormal wearing state to a normal wearing state, thereby enabling the second wearable device (520) to provide information on a second part of the user's body.

[0142] For example, the second wearable device (520) may include an affordance (e.g., a groove, an electrode, a display, or an indicator) on the outside of the second wearable device (520) to guide the normal wearing state. The processor (511) may provide a notification to the user to place (or align) the second wearable device (520) so that the second wearable device (520) operates in the normal wearing state through the affordance.

[0143] According to one embodiment, the processor (511) can identify a value for the movement of the first wearable device (510) and a value for the movement of the second wearable device (520). The processor (511) can obtain first information based on identifying that the value for the movement of the first wearable device (510) and the value for the movement of the second wearable device (520) are within a specified movement range. The processor (511) can perform operation 710 based on identifying that the value for the movement of the first wearable device (510) and the value for the movement of the second wearable device (520) are within a specified movement range. The processor (511) can obtain the first information and the second information based on identifying that the movement of the user is not identified. The processor (511) may not be able to accurately identify the positional relationship between the first wearable device (510) and the second wearable device (520) when the user moves. Therefore, the processor (511) may perform operations 710 and 720 to identify the positional relationship between the first wearable device (510) and the second wearable device (520) only when the user's movement is not identified.

[0144] FIG. 8A illustrates an example of a first rotation angle of a first wearable device according to one embodiment.

[0145] FIG. 8b illustrates an example of a second rotation angle of a second wearable device according to one embodiment.

[0146] Referring to FIG. 8A, the processor (511) of the first wearable device (510) can identify data regarding three vectors using the acceleration sensor (513-1) and / or the gyro sensor (513-2) to identify a first rotation angle of the first wearable device (510). The processor (511) can identify three vectors to identify the first rotation angle of the first wearable device (510).

[0147] According to one embodiment, the processor (511) of the first wearable device (510) is a vector ( ), vector( ), and vector ( ) can be identified. For example, the first vector ( ) is a unit vector that points from the first part to the second part (e.g., finger) of the user when the first wearable device (510) is worn on the first part (e.g., wrist) of the user's body. Vector ( ) is a unit vector pointing in the opposite direction to the direction in which the display (515) of the first wearable device (510) is facing. Vector ( ) is a vector ( ) can be perpendicular to the vector ( ) may be an acceleration value in the direction of gravity identified through the acceleration sensor (513-1) in a state where the movement of the first wearable device (510) is not identified. Since the acceleration sensor (513-1) identifies acceleration in the direction of gravity, the vector ( ) can mean the acceleration value in the direction of gravity.

[0148] For example, vector( ) is a vector ( ) and vector( ) can be distinguished. Vector( ) is composed as follows:

[0149]

[0150] In mathematical expression 1, vector ( ) is composed as in mathematical formula 2. Vector ( ) is a vector ( ) vector( ) is a projection vector for the vector ( ) is configured as in mathematical formula 3.

[0151]

[0152]

[0153] Referring to mathematical expression 3, vector ( ) is a vector ( ), vector( ) is a component belonging to a plane perpendicular to it.

[0154] The processor (511) is a vector ( ) and vector( ) between the first rotation angles ( ) can be identified. The first rotation angle ( ) is configured as in mathematical formula 4.

[0155]

[0156] As described above, the processor (511) has a first rotation angle ( ) can be identified. The first rotation angle ( ) is a vector ( ) can mean the angle of rotation based on the axis corresponding to the direction of the axis.

[0157] Referring to FIG. 8B, the processor (521) of the second wearable device (520) can identify data regarding three vectors using the acceleration sensor (523-1) and / or the gyro sensor (523-2) to identify a second rotation angle of the second wearable device (520). The processor (521) can identify three vectors to identify the second rotation angle of the second wearable device (520).

[0158] According to one embodiment, the processor (521) of the second wearable device (520) is a vector ( ), vector( ), and vector ( ) can be identified. For example, the first vector ( ) is a unit vector that points toward the tip (e.g., toward the fingernail) of the second part (e.g., finger) of the user's body when the second wearable device (520) is worn on the second part (e.g., finger) of the user's body. Vector ( ) is a unit vector in the downward direction of the second wearable device (520). For example, the vector ( ) is a unit vector of the direction in which the palm of the finger faces when the second wearable device (520) is worn on the user's finger in a normal wearing state. Vector ( ) is a vector ( ) can be perpendicular to the vector ( ) may be an acceleration value in the direction of gravity identified through the acceleration sensor (523-1) in a state where the movement of the second wearable device (520) is not identified. Since the acceleration sensor (523-1) identifies acceleration in the direction of gravity, the vector ( ) can mean the acceleration value in the direction of gravity.

[0159] For example, vector( ) is a vector ( ) and vector( ) can be distinguished. Vector( ) is composed as follows:

[0160]

[0161] In mathematical expression 5, vector ( ) is composed as in mathematical formula 6. Vector ( ) is a vector ( ) vector( ) is a projection vector for the vector ( ) is configured as in mathematical formula 7.

[0162]

[0163]

[0164] Referring to mathematical expression 7, vector ( ) is a vector ( ), vector( ) is a component belonging to a plane perpendicular to it.

[0165] The processor (521) is a vector ( ) and vector( ) between the second rotation angles ( ) can be identified. The second rotation angle ( ) is configured as in mathematical formula 8.

[0166]

[0167] As described above, the processor (521) has a second rotation angle ( ) can be identified. The second rotation angle ( ) is a vector ( ) can mean the angle of rotation based on the axis corresponding to the direction of the axis.

[0168] Referring to FIGS. 8A and 8B, the processor (511) (or processor (521)) is a vector ( ) and vector( ) can be synchronized. The processor (511) is a vector ( ) and vector( ) can be set identically. The processor (511) is a vector ( ) and vector( ) can be synchronized. The processor (511) is a vector ( ) and vector( ) can be set identically.

[0169] vector( ) and vector( ) are synchronized, and vectors ( ) and vector( ) are synchronized, the processor (511) determines the first rotation angle ( ) and the second rotation angle ( ) can be identified. The processor (511) determines the first rotation angle ( ) and the second rotation angle ( ), the second wearable device (520) can identify the size of the rotation angle on the second part of the user's body from the normal wearing state.

[0170] As described above, vector( ) and vector( ) and synchronize the vector ( ) and vector( ) will be described later in FIG. 15.

[0171] In the following drawings 9 to 13, the first rotation angle (identified according to the user's movement (e.g., the movement of the user's wrist or the movement of the finger) ) and the second rotation angle ( ) can be described as an example. In the embodiments described below, based on the synchronization procedure described later in FIG. 15, vector ( ) and vector( ) can be set identically (or similarly). Based on the synchronization procedure described later in Fig. 15, the vector ( ) and vector( ) can be set identically (or similarly).

[0172] FIG. 9 illustrates examples of a first rotation angle and a second rotation angle according to one embodiment.

[0173] Referring to FIG. 9, the first wearable device (510) can be worn on the user's wrist. The second wearable device (520) can be worn on the user's finger (e.g., index finger). The user can perform a posture (900) while wearing the first wearable device (510) and the second wearable device (520).

[0174] In detail (900), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the first rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0175] In detail (900), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the second rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0176] In the posture (900), the first rotation angle ( ) and the second rotation angle ( ) can be configured as shown in the following mathematical expression 9.

[0177]

[0178] Referring to FIG. 9, the processor (511) receives a second rotation angle ( ) can receive information about the orientation of the second wearable device (520). The processor (511) can receive information about the first rotation angle ( ) can be identified. The processor (511) can, in the posture (900), identify the first rotation angle ( ) and the second rotation angle ( ) can be identified as 0 degrees of difference.

[0179] According to an embodiment, the processor (511) of the first wearable device (510) receives a vector ( ) data, vector ( ) and data on vectors ( ) can receive data about the vector ( ) data, vector ( ) and data on vectors ( ), based on the data on the second rotation angle ( ) can be identified. The processor (511) identifies the second rotation angle ( ) and the first rotation angle ( ) can be identified as 0 degrees of difference.

[0180] FIG. 10 illustrates examples of a first rotation angle and a second rotation angle according to one embodiment.

[0181] Referring to FIG. 10, a first wearable device (510) may be worn on a user's wrist. A second wearable device (520) may be worn on a user's finger (e.g., an index finger). The user may perform a posture (1020) while wearing the first wearable device (510) and the second wearable device (520). The posture (1020) may include a posture changed according to the movement of the wrist in the posture (1010). The posture (1020) may include a posture in which the hand is moved (or rotated) in a direction (1011) in the posture (1010). For example, the posture (1010) may correspond to the posture (900) illustrated in FIG. 9.

[0182] In detail (1020), the vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the first rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0183] In detail (1010), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the second rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0184] Since the posture (1010) corresponds to the posture (900) shown in Fig. 9, in the posture (1010), the first rotation angle ( ) and the second rotation angle ( ) can be composed as follows:

[0185]

[0186] As the user's hand moves along the direction (1011), the vector ( ), vector( ), and vector ( ) may be changed. For example, as the user's hand moves (or rotates) along the direction (1011), the second wearable device (520) may also move (or rotate) along the direction (1011). Based on the second wearable device (520) moving along the direction (1011), the vector ( ) is a vector ( ) can be changed. Based on the second wearable device (520) moving along the direction (1011), the vector ( ) and vector( ) can be maintained. For example, based on the second wearable device (520) moving along the direction (1011), the vector ( ) and vector( ) can move. For example, based on the second wearable device (520) moving along the direction (1011), the vector ( ) and vector( ) can be maintained.

[0187] In detail (1020), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the second rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0188] In the detail (1020), the first rotation angle ( ) and the second rotation angle ( ) can be composed as follows:

[0189]

[0190] Referring to FIG. 10, the processor (511) receives a second rotation angle ( ) can receive information about the orientation of the second wearable device (520). The processor (511) can receive information about the first rotation angle ( ) can be identified. The processor (511) determines, in the posture (1020), the first rotation angle ( ) and the second rotation angle ( ) can be identified as 0 degrees. Even when the user's posture changes from posture (1010) to posture (1020), the first rotation angle ( ) and the second rotation angle ( ) can be identified as 0 degrees.

[0191] According to an embodiment, the processor (511) of the first wearable device (510) receives a vector ( ) data, vector ( ) and data on vectors ( ) can receive data about the vector ( ) data, vector ( ) and data on vectors ( ), based on the data on the second rotation angle ( ) can be identified. The processor (511) identifies the second rotation angle ( ) and the first rotation angle ( ) can be identified as 0 degrees of difference.

[0192] FIG. 11 illustrates examples of a first rotation angle and a second rotation angle according to one embodiment.

[0193] Referring to FIG. 11, the first wearable device (510) may be worn on the user's wrist. The second wearable device (520) may be worn on the user's finger (e.g., index finger). The user may perform a posture (1100) while wearing the first wearable device (510) and the second wearable device (520). The posture (1100) may refer to a posture in which the user's hand is moved upward (e.g., in the z-axis direction). The posture (1100) may refer to a posture in which only the user's finger is moved upward while the user's wrist is fixed.

[0194] In detail (1100), the vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the first rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0195] In detail (1100), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) as components of, for example, vectors ( ) and vector( ) can be distinguished. Vector( ) is a vector ( ) vector( ) is a projection vector for . According to the above mathematical expression 6, the vector ( ) can be identified. According to the above mathematical expression 7, the vector ( ) can be identified. Vector( ) is a vector ( ) can be parallel to each other. Therefore, the second rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0196] At the position (1100), the first rotation angle ( ) and the second rotation angle ( ) can be composed as follows:

[0197]

[0198] Referring to FIG. 11, the processor (511) receives a second rotation angle ( ) can receive information about the orientation of the second wearable device (520). The processor (511) can receive information about the first rotation angle ( ) can be identified. The processor (511) can, in the posture (1100), identify the first rotation angle ( ) and the second rotation angle ( ) can be identified as 0 degrees of difference.

[0199] For example, even if the user's posture changes from posture (900) shown in Fig. 9 to posture (1100), the vector ( ) and vector( ) may not change the plane formed by the vector ( ) and vector( ) can be maintained at 0 degrees.

[0200] According to an embodiment, the processor (511) of the first wearable device (510) receives a vector ( ) data, vector ( ) and data on vectors ( ) can receive data about the vector ( ) data, vector ( ) and data on vectors ( ), based on the data on the second rotation angle ( ) can be identified. The processor (511) identifies the second rotation angle ( ) and the first rotation angle ( ) can be identified as 0 degrees of difference.

[0201] FIG. 12 illustrates examples of a first rotation angle and a second rotation angle according to one embodiment.

[0202] Referring to FIG. 12, the first wearable device (510) may be worn on the user's wrist. The second wearable device (520) may be worn on the user's finger (e.g., index finger). The user may perform a posture (1200) while wearing the first wearable device (510) and the second wearable device (520). The posture (1200) may refer to a posture in which the user's hand moves upward (e.g., in the z-axis direction) as illustrated in FIG. 11, and the user's hand moves (or rotates) along the direction (1211). The posture (1200) may refer to a posture in which the user's wrist is fixed, only the finger moves upward, and the user's finger moves (or rotates) along the direction (1211).

[0203] In detail (1200), the vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the first rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0204] In detail (1200), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) and vector( ) can be distinguished. Vector( ) is a vector ( ) vector( ) is a projection vector for . According to the above mathematical expression 6, the vector ( ) can be identified. According to the above mathematical expression 7, the vector ( ) can be identified. Vector( ) and vector( ) between the second rotation angles ( ) can be identified.

[0205] At the position (1200), the first rotation angle ( ) and the second rotation angle ( ) can be composed as follows:

[0206]

[0207] Referring to FIG. 12, the processor (511) receives a second rotation angle ( ) can receive information about the orientation of the second wearable device (520). The processor (511) can receive information about the first rotation angle ( ) can be identified. The processor (511) determines, in the posture (1200), the first rotation angle ( ) and the second rotation angle ( ) can be identified as β(beta) degrees. For example, β(beta) degrees can be identified as less than 90 degrees depending on the user's (or person's) wrist range of motion.

[0208] According to an embodiment, the processor (511) of the first wearable device (510) receives a vector ( ) data, vector ( ) and data on vectors ( ) can receive data about the vector ( ) data, vector ( ) and data on vectors ( ), based on the data on the second rotation angle ( ) can be identified.

[0209] FIG. 13 illustrates examples of a first rotation angle and a second rotation angle according to one embodiment.

[0210] Referring to FIG. 13, the first wearable device (510) may be worn on the user's wrist. The second wearable device (520) may be worn on the user's finger (e.g., index finger). The user may assume a posture (1311) while the first wearable device (510) and the second wearable device (520) are worn. The posture (1311) may correspond to the posture (1100) illustrated in FIG. 11. While the user's posture is maintained in the posture (1311), the posture (or position, direction) of the second wearable device (520) may change. The posture of the second wearable device (520) may change from the posture (1310) to the posture (1320). Based on the second wearable device (520) being rotated in the direction (1312) while being worn on the user's finger, the posture of the second wearable device (520) can be changed from posture (1310) to posture (1320).

[0211] While the posture of the second wearable device (520) is posture (1320), with respect to the first wearable device (510), vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) can be perpendicular to the vector ( ) is a vector ( ) can be parallel to each other. Therefore, the first rotation angle ( ) can be 0 degrees (or an angle range corresponding to 0 degrees).

[0212] While the posture of the second wearable device (520) is posture (1320), the vector ( ), vector( ), and vector ( ) can be identified. Vector( ) is a vector ( ) and vector( ) can be distinguished. Vector( ) is a vector ( ) vector( ) is a projection vector for . According to the above mathematical expression 6, the vector ( ) can be identified. According to the above mathematical expression 7, the vector ( ) can be identified. Vector( ) and vector( ) between the second rotation angles ( ) can be identified.

[0213] While the posture of the second wearable device (520) is posture (1320), the first rotation angle ( ) and the second rotation angle ( ) can be composed as follows:

[0214]

[0215] Referring to FIG. 13, the processor (511) receives a second rotation angle ( ) can receive information about the orientation of the second wearable device (520). The processor (511) can receive information about the first rotation angle ( ) can be identified. The processor (511) determines, in the posture (1320), the first rotation angle ( ) and the second rotation angle ( ) can be identified as α(alpha) degrees. For example, α(alpha) degrees can be identified as less than 180 degrees as the second wearable device (520) is rotated on the user's finger.

[0216] According to an embodiment, the processor (511) of the first wearable device (510) receives a vector ( ) data, vector ( ) and data on vectors ( ) can receive data about the vector ( ) data, vector ( ) and data on vectors ( ), based on the data on the second rotation angle ( ) can be identified.

[0217] Referring to FIGS. 12 and 13, based on whether the user's posture is posture (1200) or the posture of the second wearable device (520) is posture (1320), the first rotation angle ( ) and the second rotation angle ( ) can be identified. For example, since the range of motion of the user's (or person's) wrist is limited, while the user's posture is posture (1200), the first rotation angle ( ) and the second rotation angle ( ) may be within a specified range. The first rotation angle ( identified while the posture of the second wearable device (520) is posture (1320) ) and the second rotation angle ( ) may be outside the specified range. Therefore, the first rotation angle ( of the second wearable device (520) ) and the second rotation angle ( ) is outside a specified range, the processor (511) (or processor (521)) can identify that the second wearable device (520) has been rotated while worn on the user's finger. For example, the processor (511) (or processor (521)) can identify that the first rotation angle ( ) and the second rotation angle of the second wearable device (520) ), it can be determined that the second wearable device (520) has been rotated on the user's finger.

[0218] For example, the specified range can be set as in the following mathematical formula.

[0219]

[0220] Referring to Equation 15, the specified range can be changed based on the user. For example, the specified range can be identified based on a specified model (e.g., an artificial intelligence model) indicated by a plurality of parameters. As an example, the processor (511) identifies a first rotation angle ( ) based on the wearing history of the first wearable device (510) and the second wearable device (520). ) and the second rotation angle ( ) can be used to train a specified model. The processor (511) can identify a specified range based on the output value of the (trained) specified model. The first rotation angle ( of the first wearable device (510) ) and the second rotation angle of the second wearable device (520) ) is outside the specified range and within the specified range, the specified model is identified for training the algorithm at the first rotation angle ( ) and the second rotation angle ( ) can be trained using training data having numerous (pairs) of values. For example, a designated range can be identified based on the accuracy of biometric information. The processor (511) (or the processor (521) of the second wearable device (520)) can identify the designated range based on the accuracy of data (or biometric information) acquired through the sensor (523) of the second wearable device (520).

[0221] For example, in Equation 15, γ(gamma) and δ(delta) can be set as shown in the following equation.

[0222]

[0223] According to one embodiment, the processor (511) has a first rotation angle ( ) and the second rotation angle ( ) is outside a specified range, it can be identified that the second wearable device (520) is worn in an abnormal wearing state. For example, the processor (511) may determine that the first rotation angle ( ) and the second rotation angle ( ) is outside a specified range, it can be identified that the second wearable device (520) is worn in a rotated state. If the second wearable device (520) is worn in a rotated state, the position of the sensor (523) for obtaining data about the user's body may operate in a changed state. If the second wearable device (520) is worn in a rotated state, inaccurate data may be obtained. Therefore, the processor (511) can provide a notification to guide the user to wear the second wearable device (520) in a normal wearing state. For example, the second wearable device (520) may include an affordance (e.g., a groove, an electrode, a display, or an indicator) on the outside of the second wearable device (520) to guide the normal wearing state. The processor (511) may provide a notification to guide a method of wearing the second wearable device (520) through the affordance. For example, the notification provided from the first wearable device (510) may include at least one of a screen including a user interface, a sound (e.g., voice), and / or vibration. The user may place (or arrange) the second wearable device (520) to operate in a normal wearing state through the affordance. In response to the user rotating the second wearable device (520) to a normal wearing state, the processor (511) may notify the user that the second wearable device (520) has reached the normal wearing state, and the notification provided from the first wearable device (510) may include at least one of a screen including a user interface, a sound (e.g., voice), and / or vibration.

[0224] A specific example of a notification provided by the first wearable device (510) will be described later in FIG. 14.

[0225] FIG. 14 illustrates an example of a notification for guiding a change in position or orientation of a second wearable device, according to one embodiment.

[0226] Referring to FIG. 14, in state (1410), the second wearable device (520) may be worn on a second part of the user's body (e.g., a finger). For example, the second wearable device (520) may be worn in an abnormal wearing state. The second wearable device (520) may be rotated on the second part of the user's body. The affordance (1401) on the housing of the second wearable device (520) may not be positioned in the direction in which the back of the hand faces, and may not be positioned substantially in the center, such as in the direction in which the back of the hand faces.

[0227] The processor (511) of the first wearable device (510) can identify a difference between a first rotation angle of the first wearable device (510) and a second rotation angle of the second wearable device (520). The processor (511) can identify that the difference between the first rotation angle and the second rotation angle is outside a specified range (e.g., 0 to 90 degrees).

[0228] According to one embodiment, the processor (511) may provide a notification to guide a change in at least one of the position and / or orientation of the second wearable device (520) based on identifying that a difference between the first rotation angle and the second rotation angle is outside a specified range (e.g., 0 to 90 degrees).

[0229] For example, the processor (511) may display a screen (1411) through the display (515) based on identifying that a difference between the first rotation angle and the second rotation angle is outside a specified range (e.g., 0 to 90 degrees). The processor (511) may display a screen (1411) including a user interface for guiding changing at least one of a position and / or an orientation of the second wearable device (520) based on identifying that a difference between the first rotation angle and the second rotation angle is outside a specified range (e.g., 0 to 90 degrees).

[0230] For example, the screen (1411) may include a visual object (1412) representing the shape of the second wearable device (520) and text (1413) indicating that abnormal wearing of the second wearable device (520) has been identified.

[0231] The processor (511) may display the screen (1421) after the screen (1411) is displayed. For example, the screen (1421) may be displayed based on a specified time elapsed after the screen (1411) is displayed. Based on a specified time elapsed after the screen (1411) is displayed, the processor (511) may change the screen displayed through the display (515) from the screen (1411) to the screen (1421). For example, the screen (1421) may be displayed based on an input to the screen (1411). The processor (511) may display the screen (1421) based on identifying an input (e.g., a touch input, an input to a button of the first wearable device (510)) identified while the screen (1411) is displayed. The processor (511) can display the screen (1421) based on detecting a change in the difference between the first rotation angle and the second rotation angle, but the difference between the first rotation angle and the second rotation angle is still maintained within a specified range (e.g., 0 to 90 degrees).

[0232] For example, the screen (1421) may include a visual object (1422) representing the shape and affordance of the second wearable device (520) and text (1423) for guiding a change in the position and / or orientation of the second wearable device (520). The visual object (1422) may be displayed to guide the affordance of the second wearable device (520) to face a specified direction.

[0233] In state (1420), the processor (511) can identify that the second wearable device (520) is worn in a normal wearing state. The affordance (1401) on the housing of the second wearable device (520) can be positioned in a direction toward the back of the hand. For example, the processor (511) can identify that the difference between the first rotation angle and the second rotation angle is within a specified range (e.g., 0 to 90 degrees).

[0234] Figure 15 illustrates an example of a synchronization procedure according to one embodiment.

[0235] Referring to FIG. 15, the processor (511) (or processor (521)) is a vector ( ) and vector( ) can be synchronized. The processor (511) is a vector ( ) and vector( ) can be set identically. The processor (511) is a vector ( ) and vector( ) can be synchronized. The processor (511) is a vector ( ) and vector( ) can be set identically.

[0236] The first wearable device (510) and the second wearable device (520) are vectors ( ) and vector( ) and synchronize the vector ( ) and vector( ) can perform a synchronization process to synchronize them.

[0237] In state (1510), the processor (511) may identify that the second wearable device (520) is worn. For example, the processor (511) may identify that the second wearable device (520) is worn on a second part of the user's body. Based on identifying that the second wearable device (520) is worn, the processor (511) may display a screen (1511). The screen (1511) may include text (1512) indicating that wearing of the second wearable device (520) has been detected.

[0238] At state (1520), the processor (511) may identify that a calibration process (or synchronization process) is to be performed. The processor (511) may identify that the calibration process is required to identify the first rotation angle and the second rotation angle. For example, the processor (511) may identify that the calibration process is to be performed again based on a specified time elapsed after the calibration process was performed. For example, the processor (511) may identify that the calibration process is required based on identifying that the second wearable device (520) is being worn for the first time.

[0239] According to one embodiment, the processor (511) may display a screen (1521). The screen (1521) may include a visual object (1522) indicating the wearing direction (or normal wearing state) of the second wearable device (520) and text (1523) for guiding the wearing direction.

[0240] In state (1530), the processor (511) may display a screen (1531) to guide the user's posture based on identifying that the second wearable device (520) is worn in a specified location and orientation. For example, the screen (1531) may include a visual object (1532) indicating a posture (1534) that the user should perform and text (1533) indicating the posture that the user should perform and the duration for which the posture should be maintained. In one or more embodiments, the visual object (1522) may indicate the wearing direction of the affordance (1404) on the housing of the second wearable device (520) located in the direction in which the back of the hand is facing. It should be noted that the affordance (1401) may be illustrated as being in the direction in which the back of the hand is facing, but this is for convenience of explanation and understanding. The affordance (1401) may be designed in a different orientation than the normal wearing state according to at least one embodiment.

[0241] For example, the processor (511) may guide the user to maintain the posture (1534) for a specified period of time. As an example, the processor (511) may guide the user to maintain the posture (1534) for a specified period of time through sound and / or vibration. According to an embodiment, the posture (1534) may include a state in which the user maintains the posture with the elbows and palms touching the desk while wearing the first wearable device (510) and the second wearable device (520).

[0242] While in the position (1534), the vectors shown in Figures 8a and 8b ( ) and vector( ) can be set in the same (or similar) direction. While the detail (1534) is, the vector ( ) and vector( ) can be maintained in the direction of gravity. While the posture (1534) is maintained, the processor (511) operates the vector ( ) and vector( ) can be synchronized.

[0243] In state (1540), the processor (511) may display a screen (1541) to guide the user's posture based on identifying that the posture (1534) is maintained for a specified period of time. The processor (511) may display a vector ( ) and vector( ) can be displayed to guide the user's posture based on identifying that the user's posture is synchronized.

[0244] For example, the screen (1541) may include a visual object (1542) indicating a posture (1544) that the user should perform and text (1543) indicating the posture that the user should perform and how long the posture should be maintained.

[0245] For example, the processor (511) may guide the user to maintain the posture (1544) for a specified period of time. As an example, the processor (511) may guide the user to maintain the posture (1544) for a specified period of time through sound and / or vibration.

[0246] While in detail (1544), vector ( ) and vector( ) can be set in the same (or similar) direction. While the detail (1544) is, the vector ( ) and vector( ) can be maintained in the direction of gravity. While the posture (1544) is maintained, the processor (511) operates the vector ( ) and vector( ) can be synchronized.

[0247] FIG. 16 illustrates a flowchart regarding the operation of a first wearable device according to one embodiment.

[0248] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0249] In operation 1610, the processor (511) can identify the wearing of the second wearable device (520). The processor (511) can establish a connection with the second wearable device (520). Based on data acquired through a sensor (523) of the second wearable device (520), the processor (511) can identify that the second wearable device (520) is worn on a second part of the user's body.

[0250] At operation 1620, the processor (511) may determine whether a calibration process should be performed. For example, the processor (511) may determine whether the calibration process should be performed based on identifying the wearing of the second wearable device (520). For example, the calibration process may correspond to the process illustrated in FIG. 15 .

[0251] At operation 1630, the processor (511) may perform a compensation process. For example, the processor (511) may perform the compensation process if the compensation process is to be performed. For example, the processor (511) may perform the compensation process based on identifying that the compensation process is to be performed.

[0252] For example, the processor (511) may identify that a calibration process is required to identify the first rotation angle and the second rotation angle. For example, the processor (511) may identify that the calibration process needs to be performed again based on the passage of a specified amount of time after the calibration process has been performed. For example, the processor (511) may identify that the calibration process is required based on the identification that the second wearable device (520) is being worn for the first time.

[0253] At operation 1640, the processor (511) may determine whether motion occurs during a specified period of time. For example, if a correction process does not need to be performed, the processor (511) may determine whether motion occurs during a specified period of time. For example, if a correction process has been performed, the processor (511) may determine whether motion occurs during a specified period of time, such as whether a period of time has elapsed since the last correction process was performed.

[0254] The processor (511) can identify whether the user's movement has not occurred for a specified period of time to determine whether the second wearable device (520) has rotated on the second part of the user's body. For example, if movement has occurred for the specified period of time, the processor (511) can perform operation 1640 again.

[0255] According to one embodiment, the processor (511) can identify whether no movement of the user occurs for a specified period of time based on monitoring the movement of the first wearable device (510) and the second wearable device (520).

[0256] In operation 1650, the processor (511) may identify first information and second information. For example, if no movement occurs for a specified period of time, the processor (511) may identify (or obtain) first information regarding the orientation of the first wearable device (510). The processor (511) may identify (or receive) second information regarding the orientation of the second wearable device (520).

[0257] For example, the first information may include a first rotation angle of the first wearable device (510) along a specified axis. The second information may include a second rotation angle of the second wearable device (520) along the specified axis.

[0258] In operation 1660, the processor (511) may identify whether at least one of the position or orientation of the second wearable device (520) requires a change. For example, the processor (511) may identify whether at least one of the position or orientation of the second wearable device (520) requires a change based on the first information and the second information. The processor (511) may identify whether at least one of the position or orientation of the second wearable device (520) requires a change based on whether a difference between the first rotation angle and the second rotation angle is outside a specified range.

[0259] In operation 1670, the processor (511) may provide a notification guiding a change in at least one of the position or orientation of the second wearable device (520). For example, if a change in at least one of the position or orientation of the second wearable device is required, the processor (511) may provide a notification guiding a change in at least one of the position or orientation of the second wearable device (520) based on displaying the screen (1411) and / or the screen (1412) illustrated in FIG. 14 through the display (515).

[0260] In operation 1680, the processor (511) may identify normal wearing of the second wearable device (520). For example, the processor (511) may identify that the second wearable device (520) is worn in a normal wearing state based on identifying that no change in at least one of the position or orientation of the second wearable device (520) is required.

[0261] FIG. 17A illustrates an example of an environment including a first wearable device, a second wearable device, and an electronic device, according to one embodiment.

[0262] FIG. 17b illustrates a flowchart of the operation of an electronic device according to one embodiment.

[0263] Referring to FIG. 17A, an electronic device (1701) can be connected to a first wearable device (510) and a second wearable device (520). The electronic device (1701) can control the first wearable device (510) and the second wearable device (520). For example, the electronic device (1701) (or a processor of the electronic device (1701)) can use information obtained from the first wearable device (510) and information obtained from the second wearable device (520) to identify that the second wearable device (520) is operating in an abnormal wearing state. The electronic device (1701) can provide a notification to guide changing at least one of the position or direction of the second wearable device (520) so that the second wearable device (520) can operate in a normal wearing state. For example, the notification may be provided from the electronic device (1701) or the first wearable device (510). The operation of the electronic device (1701) for providing the notification will be described in operations 1710 to 1760 of FIG. 17B.

[0264] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0265] Referring to FIG. 17B, in operation 1710, the electronic device (1701) can identify that the first wearable device (510) is worn on a first part of the user's body and the second wearable device (520) is worn on a second part of the user's body. For example, the electronic device (1701) can identify that the first wearable device (510) is worn on the first part of the user's body based on data acquired through a sensor (513) of the first wearable device (510). The electronic device (1701) can identify that the second wearable device (520) is worn on the second part of the user's body based on data acquired through a sensor (523) of the second wearable device (520).

[0266] In operation 1720, the electronic device (1701) can identify a designated axis for identifying a first rotation angle of the first wearable device (510) and a second rotation angle of the second wearable device (520).
