Description

Method for guiding the wearing direction of a wearable device and electronic device thereof

[0001] Various embodiments of the present disclosure relate to a method for guiding the wearing direction of a wearable device and an electronic device.

[0002] With the advancement of digital technology, various types of electronic devices, such as mobile terminals, personal digital assistants (PDAs), electronic notebooks, smartphones, tablet PCs (personal computers), and wearable devices, are becoming widely used. These electronic devices are constantly undergoing improvements in hardware and / or software to support and enhance their functionality.

[0003] For example, an electronic device can connect to a laptop, wearable earbuds (e.g., earphones, headphones), wearable display devices (e.g., AR glasses), and head-mounted devices (e.g., HMD, head-mounted display) using short-range wireless communication such as Bluetooth or Wi-Fi Direct to output or exchange information (or content). For example, an electronic device can connect to wearable earbuds and wearable display devices, output audio through the wearable earbuds, and output video through the wearable display devices. Considering the user's convenience, an electronic device can connect to multiple wearable devices to provide various functions.

[0004] Wearable devices have the advantage of being wearable, but if the device's location on the user's body changes, sensor information (e.g., biometric data) detected by the wearable device may become inaccurate. Inaccurate biometric data can potentially cause incorrect functions, resulting in user inconvenience.

[0005] In one embodiment, a method and device for determining a wearing direction of a wearable device based on first sensing data acquired from an IR sensor, guiding the wearing direction based on the determination result, and re-determining the wearing direction of the wearable device based on second sensing data acquired thereafter to confirm whether the wearable device is worn correctly may be disclosed.

[0006] According to one embodiment of the present disclosure, a wearable device (201) includes a biometric sensor (220), an IR sensor (225), a communication module (240), a memory (245) for storing instructions, and a processor (230), wherein the instructions, when executed by the processor, cause the wearable device to obtain first sensing data from the IR sensor when the wearable device is worn on a user's finger, determine a wearing direction of the wearable device based on the obtained first sensing data, guide the wearing direction of the wearable device based on the determination result, and after guiding the wearing direction, re-determine the wearing direction of the wearable device based on second sensing data obtained from the IR sensor.

[0007] An electronic device (101) according to an embodiment of the present disclosure includes a communication module (190), a memory (130) for storing instructions, and a processor (120), wherein the instructions, when executed by the processor, cause the electronic device to obtain first sensing data from a wearable device (201) connected through the communication module, determine a wearing direction of the wearable device based on the obtained first sensing data, provide a notification guiding the wearing direction of the wearable device based on the determination result, and after guiding the wearing direction, re-determine the wearing direction of the wearable device based on second sensing data obtained from the wearable device.

[0008] A method of operating a wearable device (201) according to an embodiment of the present disclosure may include an operation of acquiring first sensing data from an IR sensor (225) included in the wearable device when the wearable device is worn on a user's finger, an operation of determining a wearing direction of the wearable device based on the acquired first sensing data, an operation of guiding the wearing direction of the wearable device based on the determination result, and an operation of re-determining the wearing direction of the wearable device based on second sensing data acquired from the IR sensor after guiding the wearing direction.

[0009] According to one embodiment, by re-determining the wearing direction of the wearable device based on sensing data acquired after guiding the wearing direction, it is possible to efficiently confirm whether the wearable device is worn correctly.

[0010] According to one embodiment, if the wearable device is not worn correctly (e.g., worn in the wrong direction), the wearing direction of the wearable device can be quickly determined by changing the sensing cycle to a short period.

[0011] According to one embodiment, if the wearable device is not worn correctly (e.g., worn in the wrong direction), the wearing direction of the wearable device can be efficiently determined by shortening the sensing cycle after the user confirms the notification of the wearing direction.

[0012] According to one embodiment, when the wearable device is not worn correctly (e.g., worn backwards), more accurate biometric information can be provided to the user by correcting the biometric data sensed by the wearable device.

The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service.

[0057] The processor (230) may control the operation of the wearable device (201). The processor (230) may control other components included in the wearable device (201) (e.g., a touch sensor (210), an inertial sensor (215), a communication module (240), etc.) and perform various data processing or calculations. For example, the processor (230) may determine the rotational state of the wearable device (201) based on sensing data (or sensing information) acquired from the inertial sensor (215). Alternatively, the processor (230) may determine the wearing state of the wearable device (201) based on sensing information acquired from the IR sensor (225). The processor (230) may control the sensing information to be periodically transmitted to the electronic device (101) through the communication module (240). The processor (230) may include at least one of a main processor (e.g., a microcontroller unit), a sensor hub, a bay processor, or a neural processor. The processor (230) may be identical to or similar to the processor (120) of FIG. 1.

[0058] The processor (230) acquires first sensing data from the IR sensor (225) as the wearable device (201) is worn on the user's finger, determines the wearing direction of the wearable device (201) based on the acquired first sensing data, guides the wearing direction of the wearable device (201) based on the determination result, and after guiding the wearing direction, re-judges the wearing direction of the wearable device (201) based on second sensing data acquired from the IR sensor (225). For example, the processor (230) may determine the wearing direction of the wearable device (201) as a forward direction (e.g., a first direction) when the acquired first sensing data exceeds a first sensing range (or a sensing value, a sensing threshold), and may determine the wearing direction of the wearable device (201) as a reverse direction (e.g., a second direction) when the acquired first sensing data exceeds a second sensing range that is lower than the first sensing range.

[0059] The above-mentioned forward direction refers to a state in which the wearable device (201) is worn correctly, for example, the housing in which the IR sensor (225) is positioned may be worn in such a way that it comes into contact with the inside of the user's finger (e.g., the palm direction). The above-mentioned reverse direction refers to a state in which the wearable device (201) is not worn correctly, for example, the housing in which the IR sensor (225) is positioned may be worn in such a way that it comes into contact with the outside of the user's finger (e.g., the back of the hand) or the side of the finger, rather than the inside of the user's finger.

[0060] According to one embodiment, the measurement value of the IR sensor (225) when the wearable device (201) is worn correctly may be higher than the measurement value of the IR sensor (225) when the wearable device (201) is worn incorrectly. If the processor (230) determines that the wearable device (201) is worn in a reverse direction, the processor (230) may guide the user to wear the wearable device (201) in the forward direction. The processor (230) may transmit the notification to an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (201) through the communication module (240) to wear the wearable device (201) in the forward direction, and may guide the user to wear the wearable device (201) in the forward direction through the electronic device (101).

[0061] According to one embodiment, after guiding the wearing direction, the processor (230) may change the second sensing cycle shorter than the first sensing cycle of the IR sensor (225) and re-determine the wearing direction of the wearable device (201) based on the second sensing data acquired according to the changed second sensing cycle. At this time, after providing the notification of the wearing direction, the processor (230) may identify whether the user has confirmed the notification of the wearing direction, and after the user has confirmed the notification of the wearing direction, may change the second sensing cycle shorter than the first sensing cycle of the IR sensor (225).

[0062] If the acquired second sensing data exceeds the first sensing range, the processor (230) may re-evaluate the wearing direction of the wearable device (201) as forward and change the sensing cycle of the IR sensor (225) to the first sensing cycle. If the processor (230) re-evaluates the wearing direction of the wearable device (201) as forward, the processor (230) may acquire biometric data from the biometric sensor and transmit the acquired biometric data to the electronic device (101). If the processor (230) re-evaluates the wearing direction of the wearable device (201) as reverse, the processor (230) may acquire biometric data from the biometric sensor and transmit a correction notification of the acquired biometric data and the acquired biometric data to the electronic device (101).

[0063] The interface (235) may be physically connected to the wearable device case (205). For example, when the interface (235) is physically connected to the wearable device case (205), the battery (250) may be charged through the charging module (255). The charging module (255) may manage power supplied to the wearable device (201). The charging module (255) may charge the battery (250) with power received through the interface (235). The charging module (255) may be the same as or similar to the power management module (188) of FIG. 1. The battery (250) may supply power to at least one component of the wearable device (201). The battery (250) may be the same as or similar to the battery (189) of FIG. 1.

[0064] The memory (245) can map and store an angle corresponding to the touch detection range (or touch area) of the touch sensor (210). When a plurality of touch sensors (210) are mounted on the wearable device (201), the angle corresponding to the touch detection range of each touch sensor can be mapped. In addition, the memory (245) can store sensing information. The sensing information can store sensing information obtained from the inertial sensor (215) or posture information calculated by the processor (230) based on the sensing information. The sensing information can include biometric information obtained from the biometric sensor (220) and touch information obtained from the touch sensor (210). In addition, the sensing information can include proximity information when the wearable device (201) includes a proximity sensor.

[0065] Although not shown, the wearable device (201) may further include an output module capable of providing information to the user. For example, the output module may include at least one of a display (e.g., a display module (160) of FIG. 1), an LED, a speaker (e.g., an audio output device (155) of FIG. 1), and a haptic module (e.g., a haptic module (179) of FIG. 1). The output module may display notification information, light or blink an LED, output an audio signal, or output vibration under the control of the processor (230).

[0066] The wearable device case (205) may include a ring interface (260), a detection module (265), a case processor (270), a power interface (275), a case battery (280), and a case charging module (285).

[0067] The ring interface (260) may be physically connected to the interface (235) of the wearable device (201). The detection module (265) may detect whether the wearable device (201) is mounted (or accommodated) in the wearable device case (205). The detection module (265) may transmit to the case processor (270) when the wearable device (201) is mounted in the accommodation portion of the wearable device case (205). The detection module (265) may include at least one sensor that detects whether the wearable device (201) is positioned in the wearable device case (205). For example, the detection module (265) may be a circuit that periodically “pings” contact portions (e.g., the interface (235)) that are in contact with (or connected to) the wearable device (201). The detection module (265) may be a magnetic sensor, a light sensor, a switch, a Hall effect sensor, a flux sensor, a capacitive sensor, a photodetector, a proximity detector, a momentary switch, a mechanical sensor, or an electrical sensor. The case battery (280) may supply power to at least one component of the wearable device case (205). The case battery (280) may be the same as or similar to the battery (189) of FIG. 1. The power interface (275) may be physically connected to an external power source.

[0068] The case processor (270) may control the operation of the wearable device case (205). The case processor (270) may control other components included in the wearable device case (205) (e.g., detection module (265), charging module (285)) and perform various data processing or calculations. For example, when the wearable device (201) is connected, the case processor (270) may control the wearable device (201) to be charged.

[0069] The case charging module (285) can manage power supplied to the wearable device (201) or the wearable device case (205). The case charging module (285) can supply power to the wearable device (201). The case charging module (285) can charge the battery (280) with power received through the power interface (275). The case charging module (285) can be the same as or similar to the power management module (188) of FIG. 1.

[0070] FIGS. 3A and 3B are diagrams illustrating a configuration of a wearable device according to one embodiment.

[0071] FIG. 3A is a diagram illustrating a wearable device and a wearable device case according to one embodiment.

[0072] Referring to FIG. 3A, a wearable device (e.g., the wearable device (201) of FIG. 2) according to various embodiments may be accommodated (or mounted) in a wearable device case (e.g., the wearable device case (205) of FIG. 2). When the wearable device (201) is removed from the wearable device case (205), the power may be turned on. For example, when the power of the wearable device (201) is turned on, the touch sensor (210), the inertial sensor (215), the biometric sensor (220), or the IR sensor (225) may be driven. When the wearable device (201) is mounted in the wearable device case (205), the power of the wearable device (201) may be turned off or charged.

[0073] A wearable device case (205) may include a housing having a receiving portion (or space portion) configured to receive (or store) a wearable device (201) and a cover attached to the housing. The receiving portion may be configured to magnetically attract and retain the wearable device (201) within the case (250). The wearable device case (205) may control the wearable device (201) to be turned off or charged when the wearable device (201) is mounted in the receiving portion or the cover is closed.

[0074] According to one embodiment, the wearable device (201) may be formed in a circular shape. Although the drawing illustrates an example in which the wearable device (201) is formed in a circular ring shape, the wearable device (201) may be formed in various shapes such as a square or a polygon. For example, when the wearable device (201) is formed in a ring shape, even if the inner surface of the housing is formed in a circular shape in consideration of the user's wearing feeling, the outer surface of the housing may be formed in various shapes such as a square or a polygon.

[0075] The inner surface of the housing of the wearable device (201) may refer to a surface (e.g., an inner surface) that comes into contact with a finger when the user wears the ring-type wearable device (201) on the finger. The outer surface of the housing may refer to a surface (e.g., an outer surface) that does not come into contact with a finger when the user wears the ring-type wearable device (201) on the finger. When the user wears the wearable device (201) on the finger, a biometric sensor (e.g., a biometric sensor (220) of FIG. 2) or an IR sensor (e.g., an IR sensor (225) of FIG. 2) may be arranged on the inner surface of the housing so as to come into contact with the user's finger.

[0076] According to one embodiment, the wearable device (201) may be formed such that the outer surface (or area) of the housing where the IR sensor (225) is disposed is hardware-wise distinct from the outer surface of the housing where the IR sensor (225) is not disposed. For example, a small furrow (groove) may be formed on the outer surface of the housing where the IR sensor (225) is disposed.

[0077] FIG. 3b is a drawing illustrating an example of a wearable device worn on a user's finger according to one embodiment.

[0078] Referring to the reference numeral (250) of FIG. 3B, the user may wear the wearable device (201) on the user's second finger. The correct wearing direction (e.g., forward direction, first direction) of the wearable device (201) may be such that the housing in which the IR sensor (225) is disposed is in contact with the inside of the user's finger (e.g., the surface toward the palm). The incorrect wearing direction (e.g., second direction) of the wearable device (201) may be such that the housing in which the IR sensor (225) is disposed is in contact with, for example, the outside of the user's finger (e.g., the surface toward the back of the hand) or the side of the finger, rather than the inside of the user's finger. The biometric sensor (220) may obtain accurate biometric information when it comes into contact with a specific part of the user's body (e.g., the inside of the finger, the palm). If the biometric sensor (220) does not come into contact with a specific part, somewhat inaccurate biometric information may be obtained. Depending on the wearing direction of the wearable device (201), the measurement value (or signal, current) measured by the biosensor (220) or IR sensor (225) can be determined.

[0079] The wearable device (201) can identify (or determine) the wearing direction of the wearable device (201) based on sensing data acquired from the IR sensor (225). For example, if the wearable device (201) is determined to be worn in an upright position, the wearable device (201) can guide the user to the correct wearing direction of the wearable device (201). If the wearable device (201) includes an output module, the wearable device (201) can guide the user to wear the housing in which the IR sensor (225) is positioned in the palm direction through the output module. Alternatively, the wearable device (201) can guide the wearing direction through an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (201). The electronic device (101) can guide the correct wearing direction of the wearable device (201) through a user interface displayed on a display (e.g., the display module (160) of FIG. 1). The user interface can include at least one of text, an image, a video, or audio. The electronic device (101) can guide the correct wearing direction of the wearable device (201) through a voice through a speaker (e.g., the audio output module (155) of FIG. 1).

[0080] According to one embodiment of the present disclosure, a wearable device (201) includes a biometric sensor (220), an IR sensor (225), a communication module (240), a memory (245) for storing instructions, and a processor (230), wherein the instructions, when executed by the processor, cause the wearable device to obtain first sensing data from the IR sensor when the wearable device is worn on a user's finger, determine a wearing direction of the wearable device based on the obtained first sensing data, guide the wearing direction of the wearable device based on the determination result, and after guiding the wearing direction, re-determine the wearing direction of the wearable device based on second sensing data obtained from the IR sensor.

[0081] The above instructions, when executed by the processor, may cause the wearable device to determine the wearing direction of the wearable device as forward when the acquired first sensing data exceeds a first sensing range, and to determine the wearing direction of the wearable device as reverse when the acquired first sensing data exceeds a second sensing range lower than the first sensing range.

[0082] The above instructions, when executed by the processor, may cause the wearable device to guide the user to wear the wearable device in the correct direction if the wearable device is determined to be not in the correct direction.

[0083] The above instructions, when executed by the processor, may cause the wearable device to transmit to an electronic device connected to the wearable device a message to wear the wearable device in the forward direction, and to guide the user to wear the wearable device in the forward direction through the electronic device.

[0084] The above instructions, when executed by the processor, may cause the wearable device to change the first sensing cycle of the IR sensor to a second sensing cycle shorter than the first sensing cycle after guiding the wearing direction, and to re-determine the wearing direction of the wearable device based on second sensing data acquired according to the changed second sensing cycle.

[0085] The instructions, when executed by the processor, may cause the wearable device to identify whether the user has confirmed the notification of the wearing direction after providing the notification of the wearing direction, and to change the second sensing cycle of the IR sensor to a shorter first sensing cycle after the user has confirmed the notification of the wearing direction.

[0086] The above instructions, when executed by the processor, may cause the wearable device to re-determine the wearing direction of the wearable device as forward when the acquired second sensing data exceeds the first sensing range, and to cause the IR sensor to return to the first sensing cycle from the second sensing cycle.

[0087] The above instructions, when executed by the processor, may cause the wearable device to obtain biometric data from the biometric sensor and transmit the obtained biometric data to an electronic device connected to the wearable device when the wearable device re-determines the wearing direction of the wearable device as being in the forward direction.

[0088] The above instructions, when executed by the processor, may cause the wearable device to acquire biometric data from the biometric sensor when the wearable device re-determines the direction of wearing the wearable device as being reversed, and to transmit a correction notification of the acquired biometric data and the acquired biometric data to an electronic device connected to the wearable device.

[0089] An electronic device (101) according to an embodiment of the present disclosure includes a communication module (190), a memory (130) for storing instructions, and a processor (120), wherein the instructions, when executed by the processor, cause the electronic device to obtain first sensing data from a wearable device (201) connected through the communication module, determine a wearing direction of the wearable device based on the obtained first sensing data, provide a notification guiding the wearing direction of the wearable device based on the determination result, and after guiding the wearing direction, re-determine the wearing direction of the wearable device based on second sensing data obtained from the wearable device.

[0090] The above instructions, when executed by the processor, may cause the electronic device to change the cycle of a sensor for determining the wearing direction using the wearable device after guiding the wearing direction.

[0091] The above instructions, when executed by the processor, may cause the electronic device to detect whether the user has acknowledged the notification, and if the user has acknowledged the notification, to instruct the wearable device to change the cycle of a sensor for determining the wearing direction.

[0092] The above instructions, when executed by the processor, may cause the electronic device to change the cycle of a sensor for determining the wearing direction of the wearable device when the wearing direction of the wearable device is determined to be the correct direction as a result of re-determining the wearing direction of the wearable device.

[0093] The instructions, when executed by the processor, may cause the electronic device to, when the wearing direction of the wearable device is determined to be orthogonal as a result of re-determining the wearing direction of the wearable device, acquire biometric data from the wearable device and store the biometric data in the memory, and, when the wearing direction of the wearable device is determined to be non-orthogonal as a result of re-determining the wearing direction of the wearable device, acquire biometric data from the wearable device, correct the biometric data, and store the corrected biometric data in the memory.

[0094] Figure 4 is a flowchart (400) illustrating an operating method of a wearable device according to one embodiment.

[0095] Referring to FIG. 4, in operation 401, a processor (e.g., a processor (230) of FIG. 2) of a wearable device (e.g., a wearable device (201) of FIG. 2) according to an embodiment may obtain sensing data (or a sensing value, sensing information) in response to wearing the wearable device (201). The wearable device (201) may be a ring-type wearable device worn on a user's finger. The processor (230) may identify whether the wearable device (201) is worn on the user's finger using an IR sensor (e.g., an IR sensor (225) of FIG. 2) included in the wearable device (201). The processor (230) may identify whether the wearable device (201) is worn on the user's finger based on sensor data obtained from the IR sensor (225). When it is confirmed that the wearable device (201) is worn on the user's finger, the processor (230) can then obtain first sensor data from the IR sensor (225).

[0096] In operation 403, the processor (230) may determine (or identify) the wearing direction of the wearable device (201) based on the acquired sensing data. Hereinafter, the sensing data acquired in operation 401 may be described as first sensing data. If the first sensing data exceeds a first sensing range (or sensing value, sensing threshold), the processor (230) may determine the wearing direction of the wearable device (201) as a forward direction (e.g., a first direction). If the acquired first sensing data exceeds a second sensing range that is lower than the first sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as a reverse direction (e.g., a second direction). The above-mentioned forward direction refers to a state in which the wearable device (201) is worn correctly, for example, the housing in which the IR sensor (225) is positioned may be worn in such a way that it comes into contact with the inside of the user's finger (e.g., the palm direction). The above-mentioned reverse direction refers to a state in which the wearable device (201) is not worn correctly, for example, the housing in which the IR sensor (225) is positioned may be worn in such a way that it comes into contact with the outside of the user's finger (e.g., the back of the hand) or the side of the finger, rather than the inside of the user's finger.

[0097] According to one embodiment, the measurement value of the IR sensor (225) when the wearable device (201) is worn correctly may be higher than the measurement value of the IR sensor (225) when the wearable device (201) is worn incorrectly.

[0098] In operation 405, the processor (230) may guide the wearing direction according to the determination result. If the wearable device (201) is correctly worn in the forward direction as a result of the determination, the processor (230) may omit operation 405. If the wearable device (201) is not correctly worn in the forward direction (e.g., the second direction) as a result of the determination, the processor (230) may guide the wearing direction so that the user wears the wearable device (201) correctly. For example, the processor (230) may transmit information to an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (201) through a communication module (e.g., the communication module (240) of FIG. 2) to wear the wearable device (201) in the forward direction, and may guide the user to wear the wearable device (201) in the forward direction through the electronic device (101).

[0099] According to one embodiment, when the wearable device (201) further includes an output module capable of providing information to the user, the processor (230) may guide the user to wear the wearable device (201) in a forward orientation through the output module. For example, the output module may include at least one of a display (e.g., a display module (160) of FIG. 1), an LED, a speaker (e.g., an audio output device (155) of FIG. 1), and a haptic module (e.g., a haptic module (179) of FIG. 1). The output module may display notification information, light or blink an LED, output an audio signal, or output vibration under the control of the processor (230).

[0100] In operation 407, the processor (230) may re-determine the wearing direction of the wearable device (201) based on the sensing data acquired thereafter. Hereinafter, the sensing data acquired in operation 407 may be described as second sensing data. The second sensing data may refer to sensing data acquired later than the first sensing data (e.g., the sensing data acquired in operation 401). To help understanding the invention, the sensing data is divided into first and second, but the invention is not limited by the description. When the second sensing data exceeds the first sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as forward. Alternatively, when the second sensing data exceeds the second sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as reverse.

[0101] According to one embodiment, after guiding the wearing direction (e.g., after operation 405), the processor (230) may change the first sensing cycle of the IR sensor (225) to a second sensing cycle that is shorter than the first sensing cycle, and re-determine the wearing direction of the wearable device (201) based on the second sensing data acquired according to the changed second sensing cycle. The processor (230) may change the sensing cycle of the IR sensor (225) to the second sensing cycle to quickly determine the wearing direction of the wearable device (201). At this time, after providing the notification of the wearing direction, the processor (230) may identify whether the user has confirmed the notification of the wearing direction. For example, when the notification of the wearing direction is provided through the electronic device (101), the electronic device (101) may detect whether the user has confirmed the notification. The user can check the wearing direction notification by selecting (or touching) the wearing direction notification displayed on the display of the electronic device (101) (e.g., the display module (160) of FIG. 1).

[0102] When the user confirms the notification, the electronic device (101) can transmit whether or not the user has confirmed the notification to the wearable device (201). When the processor (230) is notified from the electronic device (101) that the user has confirmed the notification, the processor (230) can change the second sensing cycle of the IR sensor (225) to a shorter first sensing cycle. According to one embodiment, the processor (230) can wait (e.g., maintain the first sensing cycle) without changing the sensing cycle of the IR sensor (225) until the processor (230) is notified from the electronic device (101) that the user has confirmed the notification.

[0103] According to one embodiment, when the wearing direction of the wearable device (201) is re-determined as forward, the processor (230) may change the sensing cycle of the IR sensor (225) from the second sensing cycle to the first sensing cycle. When the wearing direction of the wearable device (201) is re-determined as forward, the processor (230) may acquire biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2) and transmit the acquired biometric data to the electronic device (101). When the wearing direction of the wearable device (201) is re-determined as reverse, the processor (230) may acquire biometric data from the biometric sensor (220) and transmit a correction notification of the acquired biometric data and the acquired biometric data to the electronic device (101). The correction notification of the acquired biometric data may be a notification (e.g., guidance) to the electronic device (101) that the biometric data is inaccurate because the wearable device (201) is not worn properly, and thus correction of the biometric data is necessary.

[0104] FIG. 5 is a diagram illustrating an example of measuring sensing data in a wearable device according to one embodiment.

[0105] Referring to FIG. 5, an IR sensor (e.g., the IR sensor (225) of FIG. 1) included in a wearable device (e.g., the wearable device (201) of FIG. 2) according to one embodiment can obtain sensing data for determining the wearing direction of the wearable device (201). For example, referring to the reference numeral (510), the IR sensor (225) can include a light receiving unit (501) and a light emitting unit (503). The IR sensor (225) can obtain the sensing data by outputting a signal through the light emitting unit (503) and obtaining a signal reflected by the signal output through the light receiving unit (501). When the wearable device (201) is properly worn in the forward direction, the light output from the light emitting unit (503) can be transmitted to the dermal layer. However, if the wearable device (201) is not worn correctly in the right direction, the light output from the light emitting unit (503) may not be transmitted to the dermis layer and may be reflected from the epidermis layer. Similarly, a biometric sensor (e.g., the biometric sensor (220) of FIG. 2) may acquire biometric data such as an electrocardiogram or blood pressure value. If the biometric data is measured as a signal reflected from the epidermis layer by the light output from the light emitting unit of the biometric sensor (220), the biometric data may not be accurate because the signal is not reflected from the dermis layer where blood vessels are present.

[0106] For example, on the outside of the finger, the light output from the light emitting unit (503) may not reach the dermis layer due to the proximity of the finger bone, and there is a high probability that it will be reflected in the epidermis layer. The first wearing state (530) illustrates an example in which the user wears the wearable device (201) in an incorrect wearing direction (e.g., reverse direction, second direction). The second wearing state (550) illustrates an example in which the user wears the wearable device (201) in the correct wearing direction (e.g., forward direction, first direction).

[0107] In the first wearing state (530), as seen in the first cross-sectional view (531) and the first front view (535), the distance between the finger bone (505) of the user's finger (507) and the IR sensor (225) of the wearable device (201) may be close. In the second wearing state (550), as seen in the second cross-sectional view (551) and the second front view (555), the distance (e.g., the second distance) between the finger bone (505) of the user's finger (507) and the IR sensor (225) of the wearable device (201) may be far. That is, the distance (e.g., the first distance) between the finger bone (505) and the IR sensor (225) in the first wearing state (530) may be shorter than the distance (e.g., the second distance) between the finger bone (505) and the IR sensor (225) in the second wearing state (550). In the first wearing state (530), light output from the IR sensor (225) may be reflected from the epidermis layer rather than the dermis layer by the finger bone (505). In the second wearing state (550), light output from the IR sensor (225) may be reflected from the dermis layer.

[0108] Blood vessels exist in the dermis layer and may be positioned closer to the inside of the finger. Therefore, measuring biometric data with a signal reflected from the dermis layer, as in the second wearing state (550), may be more accurate than measuring biometric data with a signal reflected from the epidermis layer, as in the first wearing state (530). Accordingly, the wearable device (201) may guide the correct wearing direction of the wearable device (201) so that the part where the IR sensor (225) is positioned is in contact with the inside of the finger for more accurate biometric data measurement.

[0109] FIG. 6 is a flowchart (600) illustrating a method for determining a wearing direction in a wearable device according to one embodiment. FIG. 6 may further specify operations 403 to 407 of FIG. 4.

[0110] Referring to FIG. 6, in operation 601, a processor (e.g., the processor (230) of FIG. 2) of a wearable device (e.g., the wearable device (201) of FIG. 2) according to an embodiment may identify (or determine) a wearing direction of the wearable device (201) based on sensing data. Hereinafter, the sensing data mentioned in operation 601 may be described as first sensing data. If the first sensing data exceeds a first sensing range (or sensing value, sensing threshold), the processor (230) may determine the wearing direction of the wearable device (201) as a forward direction (e.g., the first direction). If the acquired first sensing data exceeds a second sensing range that is lower than the first sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as a reverse direction (e.g., the second direction). The above-mentioned forward direction refers to a state in which the wearable device (201) is worn correctly, for example, the housing in which the IR sensor (225) is placed may be worn so that it comes into contact with the inside of the user's finger (e.g., the palm direction). The above-mentioned reverse direction refers to a state in which the wearable device (201) is not worn correctly, for example, the housing in which the IR sensor (225) is placed may be worn so that it comes into contact with the outside of the user's finger (e.g., the surface toward the back of the hand) or the side of the finger, rather than the inside of the user's finger. According to one embodiment, the measurement value of the IR sensor (225) in the case in which the wearable device (201) is worn correctly may be higher than the measurement value of the IR sensor (225) in the case in which the wearable device (201) is worn incorrectly.

[0111] In operation 603, the processor (230) can determine whether the wearing direction of the wearable device (201) is forward. If the wearing direction of the wearable device (201) is forward, the processor (120) can perform operation 613, and if the wearing direction of the wearable device (201) is not forward, the processor (120) can perform operation 605.

[0112] If the wearing direction of the wearable device (201) is not the forward direction, in operation 605, the processor (230) may provide a wearing direction notification. If the wearable device (201) is not worn correctly in the forward direction (e.g., the second direction) as a result of the determination, the processor (230) may guide the user to the wearing direction so that the wearable device (201) is worn correctly. For example, the processor (230) may transmit information to an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (201) through a communication module (e.g., the communication module (240) of FIG. 2) to wear the wearable device (201) in the forward direction, and may guide the user to wear the wearable device (201) in the forward direction through the electronic device (101).

[0113] According to one embodiment, when the wearable device (201) further includes an output module capable of providing information to the user, the processor (230) may guide the user to wear the wearable device (201) in a forward orientation through the output module. For example, the output module may include at least one of a display (e.g., a display module (160) of FIG. 1), an LED, a speaker (e.g., an audio output device (155) of FIG. 1), and a haptic module (e.g., a haptic module (179) of FIG. 1). The output module may display notification information, light or blink an LED, output an audio signal, or output vibration under the control of the processor (230).

[0114] In operation 607, the processor (230) may determine whether the user has confirmed the notification regarding the wearing direction. For example, if the wearing direction notification is provided through the electronic device (101), the electronic device (101) may detect whether the user has confirmed the notification. If the user has confirmed the notification, the electronic device (101) may transmit whether the user has confirmed the notification to the wearable device (201). The processor (230) may wait until the electronic device (101) receives the user's notification confirmation. Alternatively, operation 607 may be omitted depending on the embodiment.

[0115] In operation 609, the processor (230) may change the sensing cycle of the IR sensor (225) to be shorter. The processor (230) may change the sensing cycle of the IR sensor (225) to be shorter in order to quickly re-determine the wearing direction of the wearable device (201) when the wearable device (201) is not worn correctly in the forward direction. The sensing cycle of the IR sensor (225) may be a first sensing cycle until operation 605 or operation 607. After the processor (230) guides the wearing direction (e.g., after operation 605), the processor (230) may change the sensing cycle of the IR sensor (225) to a second sensing cycle that is shorter than the first sensing cycle. Alternatively, when the processor (230) receives a notification from the electronic device (101) that the user has confirmed the notification (e.g., after operation 607), the processor (230) may change the sensing cycle of the IR sensor (225) to a second sensing cycle that is shorter than the first sensing cycle. According to one embodiment, the processor (230) may wait (e.g., maintain the first sensing cycle) without changing the sensing cycle of the IR sensor (225) until the electronic device (101) notifies the user that the notification has been confirmed.

[0116] In operation 611, the processor (230) may re-determine the wearing direction of the wearable device (201) based on the second sensing data. Hereinafter, the sensing data acquired in operation 611 may be described as second sensing data. The second sensing data may refer to sensing data acquired later than the first sensing data (e.g., the sensing data mentioned in operation 601). When the second sensing data exceeds the first sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as forward. Alternatively, when the second sensing data exceeds the second sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as reverse.

[0117] According to one embodiment, when the wearing direction of the wearable device (201) is re-determined as forward, the processor (230) may change the sensing cycle of the IR sensor (225) from the second sensing cycle to the first sensing cycle. When the wearing direction of the wearable device (201) is re-determined as forward, the processor (230) may acquire biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2) and transmit the acquired biometric data to the electronic device (101). When the wearing direction of the wearable device (201) is re-determined as reverse, the processor (230) may acquire biometric data from the biometric sensor (220) and transmit a correction notification of the acquired biometric data and the acquired biometric data to the electronic device (101). The correction notification of the acquired biometric data may be a notification (e.g., guidance) to the electronic device (101) that the biometric data is inaccurate because the wearable device (201) is not worn properly, and thus correction of the biometric data is necessary.

[0118] When the wearable device (201) is worn in the forward direction, in operation 613, the processor (230) can acquire and transmit biometric data. The processor (230) can acquire biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2) and transmit the acquired biometric data to the electronic device (101).

[0119] FIG. 7 is a flowchart illustrating a method for guiding a wearing direction in a wearable device and electronic device according to one embodiment.

[0120] Referring to FIG. 7, in operation 701, a wearable device (e.g., the wearable device (201) of FIG. 2) according to an embodiment may be paired (or connected) with an electronic device (e.g., the electronic device (101) of FIG. 1) according to an embodiment. Pairing may mean a state in which a discovery process and a mutual authentication process between the electronic device (101) and the wearable device (201) are completed. Since the pairing operation corresponds to a conventional technology, a detailed description thereof may be omitted. When the electronic device (101) is connected to the wearable device (201), the wearable device (201) may display wearing guidance information of the wearable device (201) through a display (e.g., the display module (160) of FIG. 1). When the wearable device (201) is detected to be worn on a user's body, the wearable device (201) may periodically, in real time, or selectively transmit sensing information detected by each sensor to the electronic device (101).

[0121] For example, the sensing information may include touch information acquired from the touch sensor (210), sensing information acquired from the inertial sensor (215), posture information calculated based on the sensing information, biometric information acquired from the biometric sensor (220), or wearing direction information acquired from the IR sensor (225). The electronic device (101) may determine the user's status based on the sensing information of the wearable device (201) or utilize it as auxiliary information for controlling the function of the electronic device (101). The user's status may include at least one of sleep, exercise, work, rest, heart rate, or blood pressure status. When the electronic device (101) executes a set application (e.g., a health application), the electronic device (101) may provide the user's status information (e.g., 8 hours of sleep, quality of sleep, exercise time, work time, rest time).

[0122] In operation 703, the wearable device (201) may acquire sensing data. The sensing data may be acquired from the IR sensor (225) to determine the wearing direction of the wearable device (201). The sensing data acquired in operation 703 may be referred to as first sensing data.

[0123] In operation 705, the wearable device (201) can identify (or determine) the wearing direction of the wearable device (201). If the first sensing data exceeds a first sensing range (or sensing value, sensing threshold), the wearable device (201) can determine the wearing direction of the wearable device (201) as a forward direction (e.g., a first direction). If the acquired first sensing data exceeds a second sensing range that is lower than the first sensing range, the wearable device (201) can determine the wearing direction of the wearable device (201) as a reverse direction (e.g., a second direction). The forward direction means a state in which the wearable device (201) is properly worn, and for example, the wearable device (201) can be worn so that the housing in which the IR sensor (225) is arranged is in contact with the inside of the user's finger (e.g., a palm direction). The above reverse direction refers to a state in which the wearable device (201) is not worn correctly, for example, the housing in which the IR sensor (225) is placed may be worn so that it comes into contact with the outside of the user's finger (e.g., the back of the hand) or the side of the finger, rather than the inside of the user's finger. According to one embodiment, the measurement value of the IR sensor (225) when the wearable device (201) is worn correctly may be higher than the measurement value of the IR sensor (225) when the wearable device (201) is worn incorrectly.

[0124] In operation 707, the wearable device (201) may notify an electronic device (e.g., the electronic device (101) of FIG. 1) of the wearing direction of the wearable device (201). The wearable device (201) may transmit to the electronic device (101) whether the wearing direction of the wearable device (201) is forward or backward. Alternatively, the wearable device (201) may transmit the first sensor data to the electronic device (101), and the electronic device (101) may identify the wearing direction of the wearable device (201) based on the first sensor data.

[0125] In operation 709, the electronic device (101) may provide a notification of the wearing direction of the wearable device (201). If the wearable device (201) is not worn correctly in the correct direction (e.g., the second direction), the electronic device (101) may guide the user to the wearing direction so that the wearable device (201) is worn correctly. For example, the electronic device (101) may guide the user to the correct wearing direction of the wearable device (201) through a user interface displayed on a display (e.g., the display module (160) of FIG. 1). The user interface may include at least one of text, an image, a video, or audio. The electronic device (101) may guide the user to the correct wearing direction of the wearable device (201) through a voice through a speaker (e.g., the audio output module (155) of FIG. 1).

[0126] In operation 711, the electronic device (101) can transmit whether the wearing direction notification has been confirmed. The electronic device (101) can detect whether the user has confirmed the notification. The user can confirm the wearing direction notification by selecting (or touching) the wearing direction notification displayed on the display of the electronic device (101) (e.g., the display module (160) of FIG. 1). If the user has confirmed the notification, the electronic device (101) can transmit whether the user has confirmed the notification to the wearable device (201).

[0127] In operation 713, if the wearable device (201) is notified from the electronic device (101) that the user has checked the notification, the wearable device (201) may change the sensing cycle of the IR sensor (225) to a shorter cycle. For example, the wearable device (291) may change the sensing cycle of the IR sensor (225) set to a first sensing cycle to a second sensing cycle shorter than the first sensing cycle. According to one embodiment, if the wearable device (201) is not properly worn in the forward direction, the wearable device (291) may wait (e.g., maintain the first sensing cycle) without changing the sensing cycle of the IR sensor (225) until the wearable device (201) is not properly worn in the forward direction and is notified from the electronic device (101) that the user has checked the notification.

[0128] In operation 715, the wearable device (201) may acquire sensing data. Hereinafter, the sensing data acquired in operation 715 may be described as second sensing data. The second sensing data may refer to sensing data acquired later than the first sensing data (e.g., the sensing data acquired in operation 703). To facilitate understanding of the invention, the sensing data is divided into first and second, but the invention is not limited by the description.

[0129] In operation 717, the wearable device (201) can re-determine the wearing direction of the wearable device (201). The wearable device (201) can re-determine the wearing direction of the wearable device (201) based on the second sensing data. If the second sensing data exceeds the first sensing range, the wearable device (201) can determine the wearing direction of the wearable device (201) as forward. Alternatively, if the second sensing data exceeds the second sensing range, the wearable device (201) can determine the wearing direction of the wearable device (201) as reverse.

[0130] In operation 719, the wearable device (201) can acquire biometric data. If the wearable device (201) is determined to be worn in a forward direction, the wearable device (201) can acquire biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2). The wearable device (201) can acquire biometric data from the biometric sensor (220) in real time, periodically, or selectively (e.g., according to settings of the wearable device (201) or user settings).

[0131] In operation 721, the wearable device (201) can transmit the acquired biometric data to the electronic device (101). The wearable device (201) can transmit the acquired biometric data to the electronic device (101) in real time, periodically, or selectively (e.g., according to the settings of the wearable device (201) or user settings).

[0132] FIG. 8 is a flowchart (800) illustrating a method for guiding the wearing direction of a wearable device according to one embodiment. FIG. 8 may further specify operations 405 to 407 of FIG. 4.

[0133] Referring to FIG. 8, in operation 801, a processor (e.g., the processor (230) of FIG. 2) of a wearable device (e.g., the wearable device (201) of FIG. 2) according to an embodiment may provide a correct wearing direction notification. If the wearable device (201) is not correctly worn in the forward direction (e.g., the second direction), the processor (230) may guide the user to the correct wearing direction of the wearable device (201). For example, the processor (230) may transmit information to an electronic device (e.g., the electronic device (101) of FIG. 1) connected to the wearable device (201) through a communication module (e.g., the communication module (240) of FIG. 2) to notify the user to wear the wearable device (201) in the forward direction, and may guide the user to wear the wearable device (201) in the forward direction through the electronic device (101).

[0134] According to one embodiment, when the wearable device (201) further includes an output module capable of providing information to the user, the processor (230) may guide the user to wear the wearable device (201) in a forward orientation through the output module. For example, the output module may include at least one of a display (e.g., a display module (160) of FIG. 1), an LED, a speaker (e.g., an audio output device (155) of FIG. 1), and a haptic module (e.g., a haptic module (179) of FIG. 1). The output module may display notification information, light or blink an LED, output an audio signal, or output vibration under the control of the processor (230).

[0135] In operation 803, the processor (230) can identify whether the user has confirmed the notification regarding the wearing direction. For example, if the wearing direction notification is provided through the electronic device (101), the electronic device (101) can detect whether the user has confirmed the notification. If the user has confirmed the notification, the electronic device (101) can transmit whether the user has confirmed the notification to the wearable device (201). The processor (230) can receive whether the user has confirmed the notification regarding the wearing direction from the electronic device (101) through the communication module (240).

[0136] In operation 805, the processor (230) may change (or set) the IR sensor (225) to a second sensing cycle. The processor (230) may change the sensing cycle of the IR sensor (225) to a short cycle in order to quickly re-determine the wearing direction of the wearable device (201) if the wearable device (201) is not worn correctly in the forward direction. The sensing cycle of the IR sensor (225) may be the first sensing cycle until operations 801 and 803. The processor (230) may wait (e.g., maintain the first sensing cycle) without changing the sensing cycle of the IR sensor (225) until the electronic device (101) notifies that the user has confirmed the notification. After the user has confirmed the notification of the wearing direction (e.g., after operation 803), the processor (230) may change the sensing cycle of the IR sensor (225) to a second sensing cycle that is shorter than the first sensing cycle. According to one embodiment, after providing the notification of the wearing direction (e.g., after operation 801), the processor (230) may change to a second sensing cycle that is shorter than the first sensing cycle of the IR sensor (225).

[0137] In operation 807, the processor (230) may identify the wearing direction of the wearable device (201) based on the sensing data. Hereinafter, the sensing data acquired in operation 6807 may be described as second sensing data. The second sensing data may refer to sensing data acquired after changing to the second sensing cycle. If the second sensing data exceeds the first sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as forward. Alternatively, if the second sensing data exceeds the second sensing range, the processor (230) may determine the wearing direction of the wearable device (201) as reverse.

[0138] In operation 809, the processor (230) can determine whether the wearing direction of the wearable device (201) is forward. If the wearing direction of the wearable device (201) is forward, the processor (230) can perform operation 813, and if the wearing direction of the wearable device (201) is not forward, the processor (230) can perform operation 811.

[0139] If the wearing direction of the wearable device (201) is not the correct direction, in operation 811, the processor (230) may notify that the biometric data needs to be corrected. If the wearing direction of the wearable device (201) is re-determined as the reverse direction, the processor (230) may obtain the biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2). The processor (230) may transmit a correction notification of the obtained biometric data and the obtained biometric data to the electronic device (101) through the communication module (240). The correction notification of the obtained biometric data may be a notification (e.g., guidance) to the electronic device (101) that the biometric data is inaccurate because the wearable device (201) is not worn correctly, and thus the biometric data needs to be corrected. According to one embodiment, the processor (230) may not change the sensing cycle of the IR sensor (225) even after operation 811 (e.g., maintain the second sensing cycle). The processor (230) may determine the wearing direction of the wearable device (201) based on the sensing data acquired in the second sensing cycle even after operation 811.

[0140] If the wearing direction of the wearable device (201) is in the forward direction, in operation 813, the processor (230) can change (or set) the IR sensor (225) to the first sensing cycle. If the processor (230) determines again that the wearable device (201) is correctly worn in the forward direction, the processor (230) can change the sensing cycle of the IR sensor (225) back to the original. The processor (230) can change the sensing cycle of the IR sensor (225) from the second sensing cycle to the first sensing cycle.

[0141] In operation 815, the processor (230) can acquire and transmit biometric data. The processor (230) can acquire biometric data from the biometric sensor (220) and transmit the acquired biometric data to the electronic device (101) through the communication module (240).

[0142] FIG. 9 is a flowchart (900) illustrating a method for guiding a wearing direction in an electronic device according to one embodiment.

[0143] Referring to FIG. 9, in operation 901, 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 provide a wearing direction notification. The wearing direction notification may guide a wearing direction of a wearable device (e.g., the wearable device 201 of FIG. 2) paired with the electronic device (101). When the processor (120) is connected to the wearable device (201), the processor (120) may display wearing guidance information of the wearable device (201) through a display (e.g., the display module (160) of FIG. 1). The processor (120) may display a user interface including a correct wearing direction of the wearable device (201) on the display module (160). The user interface may include at least one of text, an image, a video, or audio. The processor (120) can guide the correct wearing direction of the wearable device (201) by voice through a speaker (e.g., the audio output module (155) of FIG. 1).

[0144] In operation 903, the processor (120) can identify (or detect) whether the user has confirmed the wearing direction notification. The user can confirm the wearing direction notification by selecting (or touching) the wearing direction notification displayed on the display module (160) of the electronic device (101). If the user has confirmed the notification, the processor (120) can transmit whether the user has confirmed the notification to the wearable device (201).

[0145] In operation 905, the processor (120) can determine whether the user has confirmed the wearing direction notification. If the user has confirmed the wearing direction notification, the processor (120) can perform operation 907, and if the user has not confirmed the wearing direction notification, the processor (120) can perform operation 906.

[0146] If the user does not confirm the wearing direction notification, in operation 906, the processor (120) may wait for a change in the sensing cycle. The processor (120) may wait for a change in the sensing cycle until the user confirms the wearing direction notification. After a certain period of time (e.g., 1 minute, 5 minutes, 10 minutes), the processor (120) may return to operation 905 to determine whether the user has confirmed the wearing direction notification. Alternatively, operation 906 may be omitted. If the user has not confirmed the wearing direction notification, the processor (120) may perform operation 905 in real time, periodically, or selectively.

[0147] If the user confirms the above-mentioned wearing direction notification, in operation 907, the processor (120) may instruct a change to the second sensing cycle. The processor (120) may instruct the wearable device (201) to change the sensing cycle of the IR sensor (e.g., the IR sensor (225) of FIG. 2) of the wearable device (201) to the second sensing cycle through a communication module (e.g., the communication module (190) of FIG. 1). Before operation 907, the IR sensor (225) of the wearable device (201) may be set to the first sensing cycle. The wearable device (201) may change the sensing cycle of the IR sensor (225) to the second sensing cycle according to the instruction of the electronic device (101).

[0148] In operation 909, the processor (120) can identify the wearing direction of the wearable device (201) based on the sensing data. The processor (120) can receive the sensing data from the wearable device (201) to identify the wearing direction of the wearable device (201). The processor (120) can receive the sensing data from the wearable device (201) after changing to the second sensing cycle. Alternatively, the processor (120) can also receive the wearing direction of the wearable device (201) from the wearable device (201).

[0149] In operation 911, the processor (120) can determine whether the wearing direction of the wearable device (201) is forward. If the wearing direction of the wearable device (201) is forward, the processor (120) can perform operation 915, and if the wearing direction of the wearable device (201) is not forward, the processor (120) can perform operation 913.

[0150] If the wearing direction of the wearable device (201) is not orthogonal, in operation 913, the processor (120) may acquire and correct biometric data from the wearable device (201). The wearable device (201) may acquire biometric data from a biometric sensor (e.g., the biometric sensor (220) of FIG. 2) and transmit the biometric data to the electronic device (101). If the wearing direction of the wearable device (201) is not orthogonal, the wearable device (201) may notify (e.g., provide guidance) to the electronic device (101) that the biometric data is not accurate and thus needs to be corrected. If the wearing direction of the wearable device (201) is not orthogonal, the processor (120) may correct the biometric data acquired from the wearable device (201) and provide the corrected biometric data to the user. The correction of the biometric data may use a correction method (or algorithm) based on the fact that the biometric data is not measured in the correct wearing direction.

[0151] If the wearing direction of the wearable device (201) is in the forward direction, in operation 915, the processor (120) may instruct to change the first sensing cycle. If the processor (120) determines again that the wearable device (201) is correctly worn in the forward direction, the processor (120) may change the sensing cycle of the IR sensor (225) back to the original. The processor (120) may instruct the wearable device (201) to change the sensing cycle of the IR sensor (225) from the second sensing cycle to the first sensing cycle.

[0152] In operation 917, the processor (120) may acquire and provide biometric data. The wearable device (201) may acquire biometric data from the biometric sensor (220) and transmit the data to the electronic device (101). The processor (120) may provide the biometric data acquired from the wearable device (201) to the user without correction. Here, providing the biometric data without correction may mean that no correction is made related to the wearing direction of the wearable device (201).

[0153] A method of operating a wearable device (201) according to an embodiment of the present disclosure may include an operation of acquiring first sensing data from an IR sensor (225) included in the wearable device when the wearable device is worn on a user's finger, an operation of determining a wearing direction of the wearable device based on the acquired first sensing data, an operation of guiding the wearing direction of the wearable device based on the determination result, and an operation of re-determining the wearing direction of the wearable device based on second sensing data acquired from the IR sensor after guiding the wearing direction.

[0154] The above-described judging operation may include an operation of judging the wearing direction of the wearable device as forward when the acquired first sensing data exceeds a first sensing range, and an operation of judging the wearing direction of the wearable device as reverse when the acquired first sensing data exceeds a second sensing range that is lower than the first sensing range.
