[0027] In the various embodiments of the present disclosure described below, a hardware-based approach is described as an example. However, since the various embodiments of the present disclosure include techniques using both hardware and software, the various embodiments of the present disclosure do not exclude a software-based approach.

[0029] Figure 1 illustrates an example of a situation in which a user wearing a finger-worn electronic device washes their hands.

[0030] FIG. 1 illustrates an example of a situation in which a user (100) washes his hands while wearing a plurality of wearable devices. When the user (100) washes his hands, the moisture level measured at at least a part of the user's (100) body (e.g., fingers (130) or wrist (150)) may change. For example, the moisture level of said body part may be referred to as skin hydration, or skin humidity.

[0031] For example, the plurality of wearable devices may include a finger-wearing electronic device (103) and a wrist-wearing electronic device (105). For example, the finger-wearing electronic device (103) may be referred to as a first wearable device, a ring, or a smart ring. For example, the wrist-wearing electronic device (105) may be referred to as a second wearable device, a watch, or a smart watch.

[0032] The finger-wearing electronic device (103) may be worn on a part of the user's (100) body. For example, the finger-wearing electronic device (103) may be worn (or contacted, adjacent to, or fitted) on the user's (100) finger (130). For example, the finger-wearing electronic device (103) may have a ring shape. The wrist-wearing electronic device (105) may be worn on another part of the user's (100) body. For example, the wrist-wearing electronic device (105) may be worn (or contacted) on the user's (100) wrist (150). In FIG. 1, the finger (130) and wrist (150) of the same arm of the user (100) are shown for convenience of explanation, but the present disclosure is not limited thereto.

[0033] Referring to FIG. 1, a finger-worn electronic device (103) and a wrist-worn electronic device (105) can each be connected to an electronic device (101). For example, the finger-worn electronic device (103) can communicate with the electronic device (101). For example, the wrist-worn electronic device (105) can communicate with the electronic device (101). Also, for example, the finger-worn electronic device (103) can communicate with the wrist-worn electronic device (105). For example, the communication can be performed using a communication technique (e.g., Bluetooth). ® , BLE(Bluetooth low energy) ® , LTE (long term evolution), 5G (5 th It may include establishing a connection using (generation), 6G). In FIG. 1, the finger-worn electronic device (103) is illustrated as communicating with the electronic device (101) and / or the wrist-worn electronic device (105), but the present disclosure is not limited thereto. For example, the finger-worn electronic device (103) may not communicate with the electronic device (101) and the wrist-worn electronic device (105) (or may not have a connection established).

[0034] For example, a user (100) may wash their hands while wearing both a finger-worn electronic device (103) and a wrist-worn electronic device (105). For example, while the user (100) is washing their hands, water (110) may come into direct contact with the finger (130) on which the finger-worn electronic device (103) is worn. In the present disclosure below, when water (110) comes into direct contact with the finger (130) or a certain part of the finger (130) comes into contact with water (110), the finger-worn electronic device (103) (or finger (130)) may be defined as being located in the water (110) (or inside the water (110). Being located in the water (110) may indicate being immersed (sink or dip) in the water (110). In contrast, if the finger (130) does not come into contact with the water (110), or if less than a certain portion of the finger (130) comes into contact with the water (110), the finger-wearing electronic device (103) (or the finger (130)) may be defined as being located outside the water (110).

[0035] For example, while the user (100) is washing their hands, the water (110) may not come into direct contact with the wrist (150) on which the wrist-worn electronic device (105) is worn. For example, as the water (110) comes into contact with a part of the user's (100) body (e.g., fingers (130)), at least some of the water (110) may splash onto the wrist (150). In other words, the water (110) may come into indirect contact with the wrist (150). However, the present disclosure is not limited thereto. If the user (100) washes not only their hands but also their arms, the wrist-worn electronic device (105) may also come into direct contact with the water (110).

[0036] Referring to FIG. 1, in real life, when a user (100) is wearing wearable devices, there is a high probability that water (110) will be exposed to parts of the user's (100) body. In the example of FIG. 1, water (110) is shown coming into contact with parts of the user's (100) body (e.g., fingers (130) or wrist (150)) while washing hands, but the present disclosure is not limited thereto. For example, water (110) may come into contact with parts of the user's (100) body (e.g., fingers (130) or wrist (150)) when the user (100) performs water sports (e.g., swimming) or performs household chores (e.g., laundry).

[0037] Referring to the above description, since the wrist-worn electronic device (105) is worn on the wrist (150), it may be difficult to detect whether a part of the user's (100) body (e.g., fingers (130)) is in direct contact with water (110). As an example without limitation, the wrist-worn electronic device (105) may recognize the user's (100) hand washing using at least one sensor of the wrist-worn electronic device (105) to guide the user (100) to properly perform hand washing. For example, the at least one sensor of the wrist-worn electronic device (105) may be a motion sensor capable of detecting the user's (100) movements or an audio sensor (e.g., a microphone, a VPU (voice pickup unit)). As a non-limiting example, a wrist-worn electronic device (105) may recognize the user (100) washing their hands by using sensing data regarding the movement of the user (100)'s wrist (150) or audio data regarding water (110). The wrist-worn electronic device (105) may recognize the user (100) washing their hands but may not recognize the results of the hand washing. For example, the results of the hand washing may include the skin hydration of the user (100)'s body part (e.g., finger (130)) that is in direct contact with the water (110).

[0038] The present disclosure can identify whether a part of a user's (100) body is located in water (110) by using a finger-worn electronic device (103) located on a part of the body that is in direct contact with water (110). The present disclosure can identify whether a part of a user's (100) body is located in water (110) and then out of water (110) by using the finger-worn electronic device (103). The present disclosure can measure the skin hydration level of the user (100) and provide a notification to the user (100) to manage hand health by using the finger-worn electronic device (103) after identifying whether the part of the user's (100) body is located in water (110). As an example, without limitation, the present disclosure can generate and provide the notification by using a trained model running on the finger-worn electronic device (103). As an example without limitation, the present disclosure may provide the notification not only directly by the finger-wearing electronic device (103), but also through an external electronic device connected to the finger-wearing electronic device (103) (e.g., a wrist-wearing electronic device (105) or an electronic device (101)).

[0039] The present disclosure allows for the detection of the skin hydration level of a part of the user's body, the time of exposure to water (110), and the frequency of exposure to water (110) when the user (100) performs at least one action with respect to water (110) as well as hand washing using a finger-worn electronic device (103). At this time, the finger-worn electronic device (103) can classify the at least one action (e.g., hand washing, water sports, household activities) and provide information for managing hand health. Accordingly, the user (100) can prevent diseases such as eczema.

[0040] Figure 2 is a schematic view of an exemplary finger-worn electronic device.

[0041] Referring to FIG. 2, a finger-worn electronic device (103) may be connected to the electronic device (101) and / or wrist-worn electronic device (105) of FIG. 1 based on a wireless network (or communication method). For example, the wireless network may include networks such as LTE (long term evolution), 5G NR (new radio), Wi-Fi (wireless fidelity), Zigbee, NFC (near field communication), Bluetooth, BLE (Bluetooth low-energy), or a combination thereof. In the example of FIG. 2, the finger-worn electronic device (103) (e.g., a smart ring) and the electronic device (101) (e.g., a smartphone, a mobile terminal) may be connected using the Bluetooth or BLE communication method. In the example of FIG. 2, the finger-worn electronic device (103) (e.g., a smart ring) and the wrist-worn electronic device (105) (e.g., a smart watch) may be connected using the Bluetooth or BLE communication method. The finger-wearing electronic device (103) of FIG. 2 may be an example of an electronic device (1302) connected to the electronic device (1301) of FIG. 13 (or the electronic device (101) of FIG. 1).

For example, at least one processor (210), at least one sensor (220), a charging circuit (230), a communication circuit (240), a memory (250), and a display (260) may be electrically and / or operably coupled with each other by a communication bus. In the following, the operably coupled hardware components may mean that a direct connection or an indirect connection between the hardware components is established via a wired or wireless connection so that a second hardware component is controlled by a first hardware component among the hardware components. Although illustrated based on different blocks, embodiments are not limited thereto, and some of the hardware components illustrated in FIG. 2 (e.g., at least one processor (210), charging circuit (230), communication circuit (240), or memory (250)) may be included in a single integrated circuit such as a system on a chip (SoC) or a system in package (SIP). The type and / or number of hardware components included in the finger-wearing electronic device (103) are not limited to those illustrated in FIG. 2. For example, the finger-wearing electronic device (103) may include only some of the hardware components illustrated in FIG. 2. As a non-limiting example, the finger-wearing electronic device (103) may not include a display (260).

[0043] According to one embodiment, at least one processor (210) of a finger-wearing electronic device (103) may include a hardware component for processing communication and / or data based on one or more instructions. The hardware component for processing data may include, for example, an arithmetic and logic unit (ALU), a floating point unit (FPU), and a field programmable gate array (FPGA). As an example, the hardware component for processing data may include a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing unit (DSP), a microcontroller (MCU), and / or a neural processing unit (NPU). For example, at least one processor (210) may have the structure of a multi-core processor such as a dual core, a quad core, or a hexa core. The at least one processor (210) of FIG. 2 may have substantially the same properties as the processor (1320) of FIG. 13.

[0044] For example, at least one processor (210) may include various processing circuits and / or multiple processors. For example, the term “processor” as used herein, including in the claims, may include various processing circuits including at least one processor, and one or more of said at least one processor may be configured to perform the various functions described below in a distributed manner, individually and / or collectively. As used below, where “processor,” “at least one processor,” and “one or more processors” are described as being configured to perform various functions, these terms encompass, for example, but not limited to, situations where one processor performs some of the cited functions and other processor(s) perform other parts of the cited functions, and also situations where one processor can perform all of the cited functions. Additionally, said at least one processor may include a combination of processors that perform the enumerated / disclosed various functions, for example, in a distributed manner. At least one processor may execute program instructions to achieve or perform the various functions.

[0045] According to one embodiment, at least one sensor (220) of the finger-wearing electronic device (103) may include an electrode sensor (221). For example, the electrode sensor (221) may be used to measure electrical characteristics (e.g., current, voltage, resistance, capacitance) using a plurality of electrodes.

[0046] For example, the plurality of electrodes of the electrode sensor (221) may be visually exposed through at least a portion of the housing of the finger-wearing electronic device (103) (e.g., the housing (300) of FIG. 3a). Specific details regarding the electrode sensor (221) may be referenced below in FIG. 3a through FIG. 5c.

[0047] As a non-limiting example, a finger-worn electronic device (103) can identify biometric information (e.g., pH (power of hydrogen), HRM (heart rate monitor), ECG (electrocardiogram), BIA (bioelectrical impedance analysis)) using an electrode sensor (221). For example, the finger-worn electronic device (103) can identify biometric information by performing processing on sensing data obtained from the plurality of electrodes to obtain the biometric information. As a non-limiting example, three electrodes of the electrode sensor (221) may be used to identify (or measure) the ECG. As a non-limiting example, four electrodes of the electrode sensor (221) may be used to identify (or measure) the BIA.

[0048] As a non-limiting example, the finger-wearing electronic device (103) can measure whether a part of a user's body (e.g., user (100) of FIG. 1) is in contact with water or measure the skin hydration level of the user's body part by identifying the electrical characteristics based on sensing data obtained using the electrode sensor (221). Measuring whether a part of the user's body is in contact with water may include determining whether the finger-wearing electronic device (103) is located in water. For example, the electrode sensor (221) may be referred to as a moisture sensing sensor, a moisture sensing module, a moisture sensor, a resistance sensor, a touch sensor, or a second sensor.

As a non-limiting example, the light-emitting part may include a light-emitting diode (e.g., LED) or a vertical cavity surface emitting laser (VCSEL) that emits light. For example, the light may include visible light or infrared light. For example, the receiver may be configured to receive reflected light of the light emitted from the light-emitting part. For example, the receiver may include an optical filter for receiving or not receiving the reflected light. As a non-limiting example, the reflected light may be reflected when the light emitted from the light-emitting part hits a part of the user's body. For example, the light-emitting part may be referred to as a light sensor, an infrared sensor, or a light-emitting element. For example, the receiver may be referred to as a light-receiving element or a light-receiving diode. In the above example, the optical sensor (223) is described as including a light-emitting part and a receiver part, but the present disclosure is not limited thereto. For example, the optical sensor (223) may include a plurality of light-emitting parts disposed at adjacent positions and a receiver part disposed at spaced-apart positions.

[0051] As a non-limiting example, a finger-worn electronic device (103) can measure whether a part of a user's body (e.g., user (100) of FIG. 1) is in contact with water or measure the skin hydration level of the user's body part by identifying the wavelength of light (or wavelength change) based on sensing data obtained using an optical sensor (223).

For example, the at least one charging port may include an electrode for charging as a wired interface, or an antenna for charging (e.g., a near field communication (NFC) antenna) as a wireless interface. In FIG. 2, the charging circuit (230) (or the PMIC of the charging circuit (230)) and at least one processor (210) are depicted as separate hardware components, but the present disclosure is not limited thereto. For example, the above PMIC and at least one processor (210) may be implemented as a single processor.

[0057] As a non-limiting example, the finger-wearing electronic device (103) can detect whether the finger-wearing electronic device (103) is located in water by identifying electrical characteristics based on data obtained through the electrode used for charging as the wired interface of the charging circuit (230).

[0058] According to one embodiment, a communication circuit (240) of a finger-worn electronic device (103) may be used to perform communication with an external electronic device (e.g., an electronic device (101) and / or a wrist-worn electronic device (105)).

For example, the electronic device (101) may be referred to as a source device, a master device, or a motor terminal for the finger-worn electronic device (103). For example, at least one processor (210) may control the operation of the communication circuit (240). As a non-limiting example, at least one processor (210) may include a processor for controlling the operation or function of the communication circuit (240). As a non-limiting example, the communication circuit (240) may include a processor for controlling the operation to perform communication with the electronic device (101) by being controlled by at least one processor (210). The processor for controlling the operation or function of the communication circuit (240) may be referred to as a communication processor or a BT processor.

The non-volatile memory may include, for example, programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), flash memory, a hard disk, a compact disk, and an embedded multimedia card (eMMC). The specific details regarding the memory (250) of FIG. 2 can be substantially applied in the same way as the details regarding the memory (1330) of FIG. 13.

[0060] According to one embodiment, within the memory (250) of the finger-wearing electronic device (103), one or more instructions (or commands) representing operations and / or actions to be performed on data by at least one processor (210) of the finger-wearing electronic device (103) may be stored. A set of one or more instructions may be referred to as a program, firmware, operating system, process, routine, sub-routine, and / or application. Hereinafter, the statement that an application is installed within the electronic device (e.g., finger-wearing electronic device (103)) may mean that one or more instructions provided in the form of an application are stored within the memory (250), and said one or more applications are stored in an executable format (e.g., a file having an extension specified by the operating system of the finger-wearing electronic device (103)) by the processor of the electronic device.

The number of displays (260) included in the finger-wearing electronic device (103) may be one or more. For example, the display (260) may be controlled by at least one processor (210) and / or a graphics processing unit (GPU) (not shown) to output visualized information to a user. The display (260) may include a flat panel display (FPD) and / or electronic paper. The FPD may include a liquid crystal display (LCD), a plasma display panel (PDP), a digital mirror device (DMD), one or more light-emitting diodes (LEDs), and / or micro LEDs. The LEDs may include organic LEDs (OLEDs). Specific details regarding the display (260) of FIG. 2 may be an example of the display module (1360) of FIG. 13. As a non-limiting example, the finger-worn electronic device (103) may not include the display (260).

[0062] As a non-limiting example, the finger-wearing electronic device (103) can detect whether the finger-wearing electronic device (103) is located in water by identifying an electrical characteristic (or a change in electrical characteristic) based on data obtained using the display (260) of the charging circuit (230) (or the touch circuit or touch panel of the display (260)).

[0063] Although not illustrated in FIG. 2, the finger-wearing electronic device (103) may include output means for outputting information in a form other than a visualized form. As an example, but not limited to, the finger-wearing electronic device (103) may further include a speaker for outputting acoustic information and an actuator (or motor) for providing haptic feedback based on vibration. Additionally, the finger-wearing electronic device (103) may include an input device (e.g., a microphone) (or an audio sensor) for acquiring (or receiving, detecting) acoustic information from the outside. For example, the audio sensor may include an accelerometer or a piezoelectric sensor that detects sound based on vibration. For example, the audio sensor may be referred to as a VPU.

[0064] Specific details regarding the structure of the finger-wearing electronic device (103) as described above are illustrated and explained below with reference to FIGS. 3a to 3c.

[0065] FIG. 3a illustrates an example of a perspective view of a finger-worn electronic device.

[0066] Referring to FIG. 3a, the finger-wearing electronic device (103) of FIG. 2 may include a housing (300) comprising a first surface (301) facing a part of the user's body (e.g., finger) and a second surface (302) opposite to the first surface (301). For example, the finger-wearing electronic device (103) may include a ring-shaped housing (300). For example, the finger-wearing electronic device (103) may be configured (or formed) in a ring shape.

[0067] For example, the finger-wearing electronic device (103) may be referred to as a wearable device that can be worn by a user. The finger-wearing electronic device (103) may be worn on a part of the user's body (e.g., a finger). For example, the finger-wearing electronic device (103) may be worn on a part of the user's body. For example, the finger-wearing electronic device (103) may be fastened to a part of the user's body. For example, the finger-wearing electronic device (103) may be detachable from a part of the user's body. For example, the finger-wearing electronic device (103) 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.

[0068] For example, the finger-worn electronic device (103) may come into contact with a part of the user's body by being worn by the user. For example, the finger-worn electronic device (103) may be configured to obtain information about the user through a part of the user's body by being worn by the user. For example, the information about the user may include the positional relationship between the user's body part and water, or the moisture (or skin hydration) of the user's body part. For example, the information about the user may include the user's biometric (or health) information. However, it is not limited thereto. For example, the finger-worn electronic device (103) may provide information about the user through the finger-worn electronic device (103) and / or an external electronic device (e.g., the electronic device (101) of FIG. 1) connected to the finger-worn electronic device (103). However, it is not limited thereto.

[0069] For example, at least a portion of the first surface (301) may come into contact with a portion of the user's body when the finger-wearing electronic device (103) is worn by the user. For example, the first surface (301) may surround a portion of the user's body where the finger-wearing electronic device (103) is worn. For example, the first surface (301) may cover a portion of the user's body where the finger-wearing electronic device (103) is worn. For example, the first surface (301) may be configured so that the finger-wearing electronic device (103) is fastened to a portion of the body by pressurizing a portion of the user's body when the finger-wearing electronic device (103) is worn by the user. For example, the first surface (301) may be deformable by a portion of the user's body. For example, the finger-worn electronic device (103) can provide information about the user through the first surface (301) based on haptic technology.

[0070] For example, the second surface (302) can form the exterior of the finger-wearing electronic device (103) together with the first surface (301). For example, the second surface (302) can form a ring-shaped housing (300) together with the first surface (301). For example, the second surface (302) may be a surface spaced apart from a part of the user's body when the finger-wearing electronic device (103) is worn by the user. For example, the first surface (301) may be referred to as the inner circumference side of the housing (300) or the inner side of the housing (300). The second surface (302), opposite to the first surface (301), may be referred to as the outer circumference side of the housing (300) or the outer side of the housing (300).

[0071] For example, the second surface (302) may be exposed to the outside while the finger-wearing electronic device (103) is worn by the user. The second surface (302) may be composed of at least one of titanium, stainless steel, and ceramic. The second surface (302) may be composed of a material for protection against external impact and / or scratches. For example, the second surface (302) may be coated with an additional material to protect the color and / or appearance of the finger-wearing electronic device (103).

[0072] For example, the first surface (301) may be composed of the same and / or similar material as the second surface (302). For example, at least a portion of the first surface (301) may be composed of at least one of a molding material for acquiring data, a transparent plastic, and / or glass. For example, at least a portion of the first surface (301) may be composed of a metal for identifying biosignals.

[0073] For example, the housing (300) may define a first surface (301), a second surface (302), and a third surface (303) between the first surface (301) and the second surface (302). For example, the third surface (303) may extend from the first surface (301) to the second surface (302). For example, the third surface (303) may be referred to as a lateral side of the housing (300). As an example without limitation, the third surface (303) may be composed of at least one of a dielectric material or a conductive material.

[0074] For example, the finger-wearing electronic device (103) may include a hole (399) formed by a first surface (301) to allow a part of the user's body to pass through when the finger-wearing electronic device (103) is worn by the user. For example, the hole (399) may be penetrated by a part of the user's body when the finger-wearing electronic device (103) is worn by the user. The finger-wearing electronic device (103) may be configured to be fastened to a part of the user's body when the user wears the finger-wearing electronic device (103) by including a hole (399) configured to allow said part of the user's body to pass through.

[0075] For example, the finger-wearing electronic device (103) may further include one or more hardware components between the first surface (301) and the second surface (302). By example, without limitation, the first surface (301), the second surface (302), and the third surface (303) may define the size and shape for receiving the one or more hardware components. For example, the finger-wearing electronic device (103) may include the communication circuit (240) of FIG. 2, at least one sensor (220), and / or at least one processor (210) between the first surface (301) and the second surface (302). Examples of the one or more hardware components and exemplary arrangements of the one or more hardware components will be described later in FIG. 3b and FIG. 3c.

[0076] FIG. 3b illustrates an example of a partial cross-sectional view of a finger-wearing electronic device. FIG. 3c illustrates an example of a partial perspective view of a finger-wearing electronic device.

[0077] Referring to FIG. 3b, the finger-wearing electronic device (103) may be formed in a ring shape. For example, the housing (300) of the finger-wearing electronic device (103) may be formed in a ring shape that can be worn on a user's finger. FIG. 3b illustrates a finger-wearing electronic device (103) in a ring shape with a smooth surface as an example, but is not limited thereto. For example, the finger-wearing electronic device (103) may be implemented as a housing comprising a plurality of planes. For example, a finger-wearing electronic device (103) in a ring shape with a non-smooth surface may also be understood as an embodiment of the present disclosure.

[0078] For example, the ring-shaped housing (300) may include a first surface (301) that contacts the user's body when worn by the user, a second surface (302) that is exposed to the outside, and a third surface (303) between the first surface (301) and the second surface (302). For example, the space between the first surface (301) and the second surface (302) may include at least one component for inclusion (or placement).

[0079] For example, a PCB (390) may be placed between the first surface (301) and the second surface (302) of the finger-wearing electronic device (103). For example, at least one processor (310), at least one sensor, a charging circuit, a communication circuit, and / or memory may be placed on the PCB (390). For example, the PCB (390) may be composed of a rigid region and a flexible region. For example, the rigid region may be referred to as a rigid flexible printed circuit board (RFPCB). For example, the flexible region may be referred to as a flexible printed circuit board (FPCB). For example, at least one processor (310) may be an example of at least one processor (210) of FIG. 2. As an example, but not limited to, the PCB (390) may be formed in a multi-layer structure. For example, the PCB (390) may include lines (or transmission lines) of the multilayer structure (e.g., 4 layers) for electrical connection between one or more components.

[0080] For example, the at least one sensor placed on the PCB (390) may include electrodes (321-1, 321-2) used as electrode sensors, an optical sensor (323-1, 323-2), a temperature sensor (325) including a temperature sensor for measuring the temperature of a user (or inside the finger-wearing electronic device (103)), a motion sensor (327) for measuring the movement of the finger-wearing electronic device (103), a temperature sensor (329) for measuring an external temperature, and a sensor package (370) including the electrode sensor and the optical sensor. The at least one sensor of FIG. 3b may be an example of the at least one sensor (220) of FIG. 2. Specific details regarding the electrodes (321-1, 321-2) which are external electrodes may be referenced below in FIG. 5a to 5c.

[0081] Specific details regarding the sensor package (370) of FIG. 3b may be referenced below in FIG. 4a to 4c. Specific details regarding the temperature sensor (325) of FIG. 3b may be referenced below in FIG. 6.

[0082] As a non-limiting example, the electrodes (321-1, 321-2) may be electrodes (or external electrodes) that are visually exposed through at least a portion of the second surface (302) (or third surface (303)) of the housing (300) of the finger-wearing electronic device (103) among the electrode sensors included in the finger-wearing electronic device (103). Alternatively, the electrodes of the temperature sensor (325) or the electrode sensor included in the sensor package (370) may be electrodes (or internal electrodes) that are visually exposed through at least a portion of the first surface (301) of the housing (300) of the finger-wearing electronic device (103) among the electrode sensors included in the finger-wearing electronic device (103). The electrodes (321-1, 321-2) of FIG. 3b may be an example of the electrode sensor (221) of FIG. 2.

[0083] As a non-limiting example, the external electrode may represent an electrode exposed through at least a portion of the second surface (302) and / or third surface (303) of the housing (300). As a non-limiting example, the external electrode may be visually exposed across a portion of the first surface (301), a portion of the second surface (302), and the third surface (303) of the housing (300), such as the electrode (321-1) shown in FIG. 3C. Unlike the external electrode, the internal electrode may represent an electrode visually exposed through at least a portion of the first surface (301) of the housing (300).

[0084] As a non-limiting example, the light-emitting part (323-1) among the optical sensors (323-1, 323-2) may be used to emit light, and the receiver part (323-2) among the optical sensors (323-1, 323-2) may be used to receive light. The optical sensors (323-1, 323-2) of FIG. 3b may be an example of the optical sensor (223) of FIG. 2. When the light emitted by the light-emitting part included in the finger-wearing electronic device (103) is visible light, the color (or wavelength) of the visible light may vary depending on the use of the light-emitting part.

[0085] For example, the charging circuit disposed on the PCB (390) may include a battery (331), an electrode (333) for wired charging, and a PMIC (335). However, the present disclosure is not limited thereto. For example, the charging circuit may include additional other components or may not include some of the components (e.g., the electrode (333)). The charging circuit of FIG. 3b may be an example of the charging circuit (230) of FIG. 2.

[0086] For example, a battery (331) may be placed between the first surface (301) and the second surface (302) of the finger-wearing electronic device (103). The battery (331) may consist of at least one battery (or battery pack). For example, the battery (331) may be configured such that at least one battery is connected in series and / or parallel. For example, the battery (331) may consist of a flexible battery pack. For example, the battery (331) may be charged and / or discharged as a secondary battery. For example, the material constituting the battery (331) may be configured in various ways. For example, the material constituting the battery (331) may include at least one of solid-state, lithium ion, and mercury. For example, a battery (331) composed of all-solid materials may include a solid electrolyte having a higher energy density and a lower risk of explosion, instead of the liquid electrolyte of a lithium-ion battery (331). However, the present disclosure is not limited to examples of the materials constituting the battery (331).

[0087] For example, the PMIC (335) may be used to manage the power of the finger-wearing electronic device (103). The PMIC (335) may be used to provide (or distribute) power to components in the finger-wearing electronic device (103) that require power. The PMIC (335) may support a wired charging method (e.g., electrode (333), pogo pin) or a wireless charging method using an antenna (341) (e.g., WPC (wireless power consortium), NFC) for charging the finger-wearing electronic device (103).

[0088] For example, the communication circuit placed on the PCB (390) may include an antenna (341) and a communication processor (343). For example, the antenna (341) may be used to communicate with an external electronic device based on a communication technique (e.g., Bluetooth, BLE). As an example, without limitation, the antenna (341) may be used for wireless charging of the finger-wearing electronic device (103). For example, the antenna (341) may be placed between the first surface (301) and the second surface (302) of the finger-wearing electronic device (103). For example, the antenna (341) may be composed of a single antenna and / or multiple segmented antennas. For example, the antenna (341) may be formed as part of the housing (300) of the finger-wearing electronic device (103). For example, the antenna (341) may be electrically connected to the communication processor (343) through the PCB (390). The arrangement of the antenna (341) of the finger-worn electronic device (103) is merely exemplary for convenience of explanation and is not limited thereto. For example, in FIG. 3b, the communication processor (343) is shown as a separate component from at least one processor (310), but is not limited thereto. The communication circuit of FIG. 3b may be an example of the communication circuit (240) of FIG. 2.

[0089] For example, a microphone (380) (or a piezoelectric sensor, an accelerometer) may be placed on the PCB (390). For example, an actuator (385) for providing haptic feedback may be placed on the PCB (390).

[0090] For example, the display (360) may be disposed on at least one surface of the housing (300). As an example without limitation, the display (360) may be disposed on a second surface (302) of the housing (300). For example, the display (360) may include a touch sensor (or touch panel).

[0091] FIG. 3c illustrates an example of a partial perspective view of a finger-wearing electronic device (103) to explain the positions of the electrodes (321-1, 321-2) of the finger-wearing electronic device (103) of FIG. 3b. For example, the partial cross-sectional view of the finger-wearing electronic device (103) of FIG. 3c may show a drawing in which internal components are visually exposed through the first surface (301).

[0092] Referring to FIG. 3c, the finger-wearing electronic device (103) may include a PCB (390). For example, the PCB (390) may be placed inside the housing (300) of the finger-wearing electronic device (103). In the example of FIG. 3c, for convenience of explanation, some of the components included in the finger-wearing electronic device (103) are shown, but the present disclosure is not limited thereto.

[0093] Referring to FIG. 3c, the battery (331), the electrode for wired charging (333), the PMIC (335), the antenna (341), and the electrodes (321-1, 321-2) used as electrode sensors may be placed on the PCB (390). As a non-limiting example, the electrode for wired charging (333) may be visually exposed through a portion of the first surface (301) of the housing (300). As a non-limiting example, the electrode (321-1) among the electrodes (321-1) may be visually exposed through a portion of the first surface (301), a portion of the second surface (302), and a third surface (303) of the housing (300). In other words, the electrode (321-1) may have a 'C' shape. As a non-limiting example, electrode (321-2) among the electrodes (321-1, 321-2) may be visually exposed through at least a portion of the second surface (302) of the housing (300). For example, the electrodes (321-1, 321-2) may be used to obtain data indicating electrical characteristics by being positioned toward the outside of the finger-wearing electronic device (103). Specific examples of the positioning state, connection state, and positional relationship of the electrodes (321-1, 321-2) may be referenced in FIGS. 5a through 5c.

[0094] FIG. 4a illustrates an example of a perspective view of a sensor package of a finger-worn electronic device.

[0095] Referring to FIG. 4a, a sensor package (370) included in the housing (300) of the finger-wearing electronic device (103) of FIG. 3b is shown. For example, the sensor package (370) may be mounted (or placed) on a PCB (390).

[0096] The sensor package (370) may include a first sensor (410) and a second sensor (420). For example, the first sensor (410) may be an example of the optical sensor (223) of FIG. 2. For example, the second sensor (420) may be an example of the electrode sensor (221) of FIG. 2. It may include an enclosure (400) that forms (or defines) the exterior of the sensor package (370).

[0097] For example, the enclosure (400) may accommodate a first sensor (410). For example, the light-emitting part (411) of the first sensor (410) may be accommodated within the enclosure (400). For example, the receiver part (412) of the first sensor (410) may be accommodated within the enclosure (400). In FIGS. 4a and 4b, the first sensor (410) is illustrated as including one light-emitting part (411) and one receiver part (412), but the present disclosure is not limited thereto. For example, the first sensor (410) may include two light-emitting parts or three or more components. Specific details regarding the first sensor (410) accommodated within the enclosure (400) may be referenced below in FIG. 4b.

[0098] For example, the second sensor (420) may be placed on a surface forming the exterior of the enclosure (400). For example, the surface forming the exterior of the enclosure (400) may be referred to as the top side of the enclosure (400). For example, the second sensor (420) may include a first electrode (421) and a second electrode (422). For example, the first electrode (421) may include a first portion (421a) and second portions (421b) extending from the first portion (421a). For example, the second portions (421b) may be spaced apart from each other. For example, the second electrode (422) may include a third portion (422a) and fourth portions (422b) extending from the third portion (422a). For example, the fourth parts (422b) may be spaced apart from each other. For example, the second parts (421b) and the fourth parts (422b) may be intersected (or interleaved, or alternately arranged). As a non-limiting example, the second parts (421b) and the fourth parts (422b) may be spaced apart and intersected so that each of the first electrode (421) and the second electrode (422) may have a comb shape. The second sensor (420) having a comb shape can relatively easily perform the acquisition of data for identifying electrical characteristics (e.g., resistance) by utilizing a relatively large cross-sectional area.

[0099] For example, a portion of the sensor package (370) may be visually exposed through a portion of the first surface (301) of the housing (300). By example, without limitation, said portion may include a second sensor (420). By example, without limitation, said portion may include the second sensor (420) and the top side of the enclosure (400).

[0100] FIG. 4b illustrates an example of a partial cross-sectional view of a sensor package.

[0101] Referring to FIG. 4b, a sensor package (370) may be placed on a PCB (390). For example, the sensor package (370) may be electrically connected to pads (490) on the PCB (390) through connecting members (480). As a non-limiting example, the PCB (390) may include pads (490) to increase the possibility of electrical connection. For example, the pads (490) may be used to reduce electrical disconnection that may be caused by tolerance. For example, each connecting member (480) may be placed on each of the pads (490).

[0102] The sensor package (370) may include an enclosure (400). For example, the enclosure (400) may form (or define) the exterior of the sensor package (370). For example, the enclosure (400) may include a cover (401) that defines the top side of the exterior of the sensor package (370). For example, the enclosure (400) may include a wall (402) that defines the lateral side of the exterior of the sensor package (370). For example, the enclosure (400) may include a substrate (403) that defines the bottom side of the exterior of the sensor package (370). For example, the enclosure (400) may include a partition wall (405) between spaces for accommodating the first sensor (410). For example, the enclosure (400) can be made of plastic.

[0103] For example, the spaces may include a first space and a second space. Each of the spaces may be defined by a cover (401), a wall (402), a substrate (403), and a partition wall (405). For example, the first space may include a first light-transmitting portion (431) including a first opening (431a) and a first portion (431b). For example, the second space may include a second light-transmitting portion (432) including a second opening (432a) and a second portion (432b). For example, the opening may be referred to as a window.

[0104] For example, at least a portion of the first space may be filled with a material (e.g., epoxy) that transmits light and prevents water from entering from the outside of the sensor package (370). The material may be referred to as a light-transmitting material. For example, the at least portion of the first space filled with the material may include a first light-transmitting portion (431) and a first opening (431a). For example, at least a portion of the second space may be filled with a material (e.g., epoxy) that transmits light and prevents water from entering from the outside of the sensor package (370). However, the present disclosure is not limited thereto. For example, the at least portion of the first space filled with the material may include a first light-transmitting portion (431), a first opening (431a), and a first portion (431b). The material may be referred to as a light-transmitting material. For example, the at least portion of the second space filled with the material may include a second light-transmitting portion (432) and a second opening (432a). However, the present disclosure is not limited thereto. For example, the at least portion of the second space filled with the material may include a second light-transmitting portion (432), a second opening (432a), and a second portion (432b).

[0105] For example, a light-emitting part (411) of the first sensor (410) may be accommodated within the first space of the enclosure (400). For example, the light-emitting part (411) may be placed on a substrate (403) corresponding to the first space. For example, the light-emitting part (411) may be placed in an area of ​​the substrate (403) corresponding to the first opening (431a) to emit light toward the outside of the housing (300). For example, the light-emitting part (411) may be placed below the first light-transmitting part (431). The first part (431b) may represent a part below the first light-transmitting part (431) (or a part below the light-emitting part (411)) within the first space.

[0106] For example, a receiver (412) of the first sensor (410) may be accommodated within the second space of the enclosure (400). For example, the receiver (412) may be placed on a substrate (403) corresponding to the second space. For example, the receiver (412) may be placed in an area of ​​the substrate (403) corresponding to the second opening (432a) to receive reflected light from outside the housing (300). For example, the receiver (412) may be placed below the second light-transmitting portion (432). The second portion (432b) may represent a portion below the second light-transmitting portion (432) (or a portion below the receiver (412)) within the second space.

[0107] As described above, in FIG. 4b, the first sensor (410) is illustrated as including one light-emitting part (411) and one receiver part (412), but the present disclosure is not limited thereto. For example, the first sensor (410) may include two light-emitting parts or three or more components.

[0108] The partition wall (405) of the enclosure (400) may include (or define) a surface (405a) that forms the exterior of the enclosure (400). For example, the surface (405a) may be part of a cover (401) that defines the top side of the enclosure (400). As a non-limiting example, a second sensor (420) may be placed on the surface (405a). However, the present disclosure is not limited thereto. For example, the second sensor (420) may be placed on a cover (401) that includes the surface (405a). Specific details regarding this may be referenced in FIG. 4c.

[0109] A second sensor (420) disposed on the surface (405a) may include a first electrode (421) and a second electrode (422). For example, the second sensor (420) may include a via (425) for electrical connection between the first electrode (421) or the second electrode (422) and a sensor processor (or sensor IC (integrated circuitry)). As an example without limitation, the sensor processor may be included in at least one processor (310) of FIG. 3b (or at least one processor (210) of FIG. 2) or controlled by at least one processor (310) of FIG. 3b (or at least one processor (210) of FIG. 2). For example, the via (425) may be disposed within the partition wall (405). For example, a first pad (427-1) may be included to reduce (or prevent) the tolerance that may occur between the partition wall (405) and the surface (405a) of the partition wall (405). For example, the first pad (427-1) may be placed below the surface (405a) of the partition wall (405). Additionally, a second pad (427-2) may be included to reduce (or prevent) the tolerance that may occur between the partition wall (405) and the substrate (403). For example, the second pad (427-2) may be placed between the partition wall (405) and the substrate (403).

[0110] Referring to FIG. 4b, the sensor package (370) may be implemented via an AoP (antenna on package) or TMV (through mold via) interposer to place the electrodes (421, 422) of the second sensor (420) on a part of the enclosure (400) (e.g., a surface (405a)). As an example without limitation, the partition wall (405) may be formed via molding. Alternatively, the sensor package (370) may be implemented via a package assembly including the electrodes (421, 422). By using the sensor package (370) in which the first sensor (410) and the second sensor (420) are implemented through a single device (or package), internal mounting space of the finger-wearing electronic device (103) can be secured. In addition, when using the sensor package (370), the positions of the first sensor (410) and the second sensor (420), which can be used to measure moisture in a body part of a user (e.g., user (100) of FIG. 1), are similar, so the accuracy of the measurement using different types of data (e.g., sensor data according to the optical sensor and sensor data according to the electrode sensor) can be increased.

[0111] FIG. 4c illustrates an example of the structure of the electrodes of a sensor package.

[0112] Referring to FIG. 4c, an example of the structure of the second sensor (420) (or electrodes (421, 422) of FIG. 4a and 4b) is illustrated. Unlike the second sensor (420) positioned between the first sensor (410) (or between the first opening (431a) and the second opening (432a)) as illustrated in FIG. 4a and 4b, FIG. 4c illustrates a second sensor (420) positioned to surround the first opening (431a) and the second opening (432a).

[0113] Referring to FIG. 4c, the second sensor (420) may include a first electrode (421) and a second electrode (422). The second sensor (420) of FIG. 4c may have a shape different from the comb shape exemplified in FIG. 4a and FIG. 4b. For example, the first electrode (421) of the second sensor (420) may be placed on a portion of the cover (401) defining the first opening (431a) and the second opening (432a). Also, for example, the second electrode (422) of the second sensor (420) may be placed on a portion of the cover (401) defining the first opening (431a) and the second opening (432a). In this case, the second electrode (422) may be spaced apart from the first electrode (421).

[0114] As illustrated in FIG. 4c, the cross-sectional area of ​​the second sensor (420) can be increased by arranging the first electrode (421) and the second electrode (422), respectively, to surround the openings (431a, 432a). Accordingly, the accuracy of the data measured by the second sensor (420) can be increased. The structure of the first electrode (421) and the second electrode (422), respectively, illustrated in FIG. 4c is merely exemplary and the present disclosure is not limited thereto.

[0115] FIG. 5a illustrates examples of electrodes placed on the housing of a finger-wearing electronic device.

[0116] FIG. 5a illustrates examples (501, 502, 503, 504) of electrodes (or external electrodes) disposed on the housing (300) of a finger-wearing electronic device (103). The examples (501, 502, 503, 504) illustrated in FIG. 5a are merely exemplary states in which electrodes are disposed, and the present disclosure is not limited thereto.

[0117] Referring to example (501), electrodes (511, 512) may be placed on a third surface (303) of the housing (300). For example, the third surface (303) of the housing (300) may be formed of an insulating material (or an insulator). For example, electrode (511) may be placed in a portion of the third surface (303) (e.g., 12 o'clock direction), and electrode (512) may be placed in a different portion of the third surface (303) (e.g., 6 o'clock direction). For example, each of electrode (511) and electrode (512) may be surrounded by the third surface (303) formed of an insulating material. For example, electrode (511) and electrode (512) may be an example of an electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0118] Referring to example (502), the electrode (520) may be placed on a third surface (303) of the housing (300). For example, the third surface (303) of the housing (300) may be formed of an insulating material (or an insulator). For example, the electrode (520) may be placed in a portion of the third surface (303) (e.g., 12 o'clock direction). For example, the electrode (520) may be surrounded by the third surface (303) formed of an insulating material. Unlike example (501), in example (502), one electrode (520) may be placed on the third surface (303). For example, the electrode (520) may be an example of an electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0119] Although not illustrated in the example (502) of FIG. 5a, the housing (300) may further include other electrodes. For example, the other electrode may be placed on a different part of the third surface (303) (e.g., back) opposite to the part of the third surface (303) (e.g., front) shown in the example (502) of FIG. 5a. For example, the different part of the third surface (303) may represent a side opposite to the part of the third surface (303) with respect to the second surface (302). For example, the different part of the third surface (303) may be formed of an insulating material. For example, the other electrode may be placed in a portion of the different part of the third surface (303). As a non-limiting example, the portion of the different part of the third surface (303) where the other electrode is placed may be at the 6 o'clock position. This may be because the portion of the part of the third surface (303) where the electrode (521) is placed is at the 12 o'clock position. For example, the other electrode may be surrounded by the third surface (303) formed of an insulating material. In other words, unlike example (501), in example (502), electrodes may be placed in different parts of the third surface (303) rather than in the same part (or front side).

[0120] Referring to example (503), the electrode (530) may be placed on a second surface (302) of the housing (300). For example, the second surface (302) of the housing (300) may be formed of a conductive material and an insulating material (or an insulator). For example, the electrode (530) may be placed in a portion of the second surface (302). The portion may be surrounded by an insulating material (535) forming the second surface (302). The remaining portion of the second surface (302), excluding the insulating material (535), may be formed of a conductive material or of a conductive material and an insulating material. For example, the electrode (530) may be an example of an electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0121] Referring to Example (504), the electrode (530) may be disposed on the third surface (303) of the housing (300). For example, the third surface (303) of the housing (300) may be formed of an insulating material (or an insulator). In Example (504), unlike Examples (501, 502, 503), the area of ​​the third surface (303) may be formed narrowly by the conductive portion of the first surface (301) of the housing (300) and the conductive portion of the second surface (302). For example, the first thickness of the conductive portion of the first surface (301) of each of Examples (501, 502, 503) may be thinner than the second thickness of the conductive portion of the second surface (302). However, the present disclosure is not limited thereto. The third surface (303) may be formed by an insulating material (or insulator) that constitutes the remaining space excluding the space defined by the first thickness and the second thickness. In example (504), as the thickness of the first surface (301) is formed to the second thickness, the space of the third surface (303) may be relatively narrow. At this time, in order to place the electrode (540) in a part area (e.g., 12 o'clock direction) of the third surface (303), the third surface (303) may include an insulating material (545) as in example (503). For example, the part area of ​​the third surface (303) where the electrode (540) is placed may be surrounded by the insulating material (545). For example, the electrode (540) may be an example of an electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0122] As illustrated in examples (501, 502, 503, 504), the external electrode may be placed on a part of the second surface (302) or the third surface (303) of the housing (300) of the finger-wearing electronic device (103). Additionally, the external electrode illustrated in the examples (501, 502, 503, 504) of FIG. 5a is shown as being formed in a circular shape, but the present disclosure is not limited thereto. For example, as with the electrode (321-1) of FIG. 3c, the external electrode may be placed on at least a part of the second surface (302) and the third surface (303) (and the first surface (301)) by having a 'C' shape.

[0123] FIG. 5b illustrates an example of the connection state between a printed circuit board (PCB) and an electrode within a finger-wearing electronic device.

[0124] Referring to FIG. 5b, an example (550) of the connection state between the PCB (390) and the electrode (551) within the finger-wearing electronic device (103) is illustrated. The example (550) in FIG. 5b may represent an enlarged view of the area containing the electrode (321-1) within a partial cross-sectional view of the finger-wearing electronic device (103) of FIG. 3b. The electrode (551) in FIG. 5b may be an example of an external electrode that is visually exposed through a second surface (302) (or a third surface (303)) on the housing (300). For example, the electrode (551) may be an example of the electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0125] Referring to FIG. 5b, the PCB (390) may include a first part (390a) and a second part (390b). In FIG. 5b, for convenience of explanation, the first part (390a) and the second part (390b) are shown as separated, but the present disclosure is not limited thereto. For example, the first part (390a) and the second part (390b) may be connected through other parts of the PCB (390).

[0126] In the example (550) of FIG. 5b, the first portion (390a) of the PCB (390) may represent a portion of the PCB (390) that is not connected to the electrode (551). The first portion (390a) may be placed (or mounted, assembled, or fixed) in an area (or edge) of the insulating material (555) inside the housing (300). Accordingly, the first portion (390a) may be at least partially surrounded by the insulating material (555) inside the housing (300). Alternatively, the second portion (390b) of the PCB (390) may represent a portion of the PCB (390) that is connected to the electrode (551). For example, the second portion (390b) may be connected to the electrode (551) through a pad (559) placed in an opening portion that is not included in the insulating material (555) inside the housing (300). For example, the second part (390b) may be covered by a pad (559) so as not to come into contact with a substance (e.g., water) from the outside and may be hidden from view from the outside. For example, the second part (390b) may be electrically connected to the electrode (551) through the pad (559). For example, the electrode (551) may be surrounded by an insulating material (555) so as not to be visible from the outside of the finger-wearing electronic device (103). A portion (553) of the electrode (551) may come into contact with the pad (559).

[0127] FIG. 5c illustrates an example of the positional relationship of electrodes placed on the housing of a finger-wearing electronic device.

[0128] FIG. 5c illustrates a cross-sectional view of a finger-wearing electronic device (103) in the xy plane when viewed from the +z axis direction. Referring to FIG. 5c, the finger-wearing electronic device (103) may include electrodes (551a, 551b). Each of the electrodes (551a, 551b) in FIG. 5c may be an example of the electrode (551) in FIG. 5b. In other words, each of the electrodes (551a, 551b) in FIG. 5c may be an example of an external electrode that is visually exposed through a second surface (302) (or a third surface (303)) on the housing (300). For example, the electrodes (551a, 551b) may be an example of the electrode sensor (221) of at least one sensor (220) in FIG. 2.

[0129] For example, the electrode (551a) may be placed at a first position (561) on the second surface (302) of the finger-wearing electronic device (103). By example, without limitation, the first position (561) may be located in the +y-axis direction and the -x-axis direction within the housing (300) of the finger-wearing electronic device (103). For example, the electrode (551b) may be placed at a second position (562) on the second surface (302) of the finger-wearing electronic device (103). By example, without limitation, the second position (562) may be located in the -y-axis direction and the +x-axis direction within the housing (300) of the finger-wearing electronic device (103). In other words, the first position (561) may be placed furthest from the second position (562) on the housing (300) (or the second surface (302)) of the finger-wearing electronic device (103). As a non-limiting example, the distance (565) between the first position (561) (or a point of the first position (561)) and the second position (562) (or a point of the second position (562)) may be longer than the diameter (570) of the circle formed by the second surface (302) of the finger-wearing electronic device (103).

[0130] For example, the finger-wearing electronic device (103) can acquire sensing data using electrodes (551a, 551b) placed at a first position (561) and a second position (562). For example, the finger-wearing electronic device (103) can identify electrical characteristics (or changes in electrical characteristics) using the acquired sensing data. At this time, by using the electrodes (551a, 551b) placed at the first position (561) and the second position (562), the finger-wearing electronic device (103) can more accurately identify the positional relationship between the finger of the user wearing the finger-wearing electronic device (103) and water. In other words, since the first position (561) and the second position (562) are located furthest from the finger-wearing electronic device (103), the finger-wearing electronic device (103) can more accurately determine whether part of the finger-wearing electronic device (103) is located in water or the whole of the finger-wearing electronic device (103) is located in water by using the electrodes (551a, 551b) of the first position (561) and the second position (562).

[0131] FIG. 6 illustrates an example of a perspective view of a temperature sensor for a finger-worn electronic device.

[0132] Referring to FIG. 6, a temperature sensor (325) included in the housing (300) of the finger-wearing electronic device (103) of FIG. 3b is shown. For example, the temperature sensor (325) may be placed on a PCB (not shown) (e.g., the PCB (390) of FIG. 3b).

[0133] The temperature sensor (325) may include a first part (610), a second part (620), and an electrode (630). For example, the first part (610) may be a part that contacts (or is placed on) the PCB. For example, the first part (610) may be referred to as a package substrate or a sensor package substrate. For example, the first part (610) may be composed of a material with relatively low thermal conductivity. For example, the second part (620) may be placed on the first part (610). For example, the second part (620) may be a material with relatively high thermal conductivity. As an example, but not limited to, a finger-worn electronic device (103) may measure the temperature of the user's finger through the electrode (630) of the temperature sensor (325) when worn on the user's finger. Heat from the user's finger in contact with the electrode (630) may be conducted to the second part (620). The temperature sensor (325) can measure the temperature using the heat in the second part (620). As a non-limiting example, the temperature sensor (325) may include a heat-conducting material in the space between the electrode (630) and the second part (620) to conduct the heat from the electrode (630) to the second part (620). As a non-limiting example, the temperature sensor (325) may include a pin extending from the second part (620) to conduct the heat from the electrode (630) to the second part (620). For example, the pin may be composed of a material for conducting the heat. For example, the pin may be connected from the second part (620) to the electrode (630) through the PCB on which the temperature sensor (325) is mounted or through the first part (610). In the example of FIG. 6, a temperature sensor (325) including a temperature sensor for measuring the temperature of a finger as shown in FIG. 3b is shown, but the present disclosure is not limited thereto.The description of the temperature sensor (325) in Fig. 6 can be substantially applied to a structure including a temperature sensor (329) and an electrode for measuring the external temperature of a finger-worn electronic device (103).

[0134] As a non-limiting example, the first part (610) of the temperature sensor (325) may be mounted on the PCB. For example, the first part (610) may be mounted (or installed) on the surface of the PCB via a connecting member (e.g., a pin, a ball, a pad).

[0135] As a non-limiting example, the electrode (630) of the temperature sensor (325) may surround the second part (620) of the temperature sensor (325). For example, as shown above in FIG. 6, the electrode (630) may cover the second part (620) of the temperature sensor (325) so that it is not visible from the outside of the temperature sensor (325). For example, the second part (620) may be covered by the electrode (630) when viewing the temperature sensor (325) in the z-axis direction. For example, a part of the electrode (630) may be in contact with the first part (610) of the temperature sensor (325). However, the present disclosure is not limited thereto. For example, the electrode (630) of the temperature sensor (325), illustrated below in FIG. 6, may be positioned so that a portion of the second part (620) of the temperature sensor (325) is not visible from the outside of the temperature sensor (325), and another portion of the second part (620) is visible from the outside of the temperature sensor (325). In this case, the electrode (630) may have a 'C' shape. For example, the second part (620) may not be covered by the electrode (630) when viewing the temperature sensor (325) in the z-axis direction. The shape of the electrode (630) illustrated in FIG. 6 is merely exemplary and the present disclosure is not limited thereto.

[0136] A temperature sensor (325) having a structure in which a second part (620) is completely covered by an electrode (630) shown above in FIG. 6 can be robust against a molding for forming a housing (300) (or a first surface (301) of the housing (300)) of a finger-wearing electronic device (103). For example, when forming the housing (300) through molding, the second part (620) of the temperature sensor (325) can be shielded from the molding material filled by the electrode (630). Thus, compared to the temperature sensor (325) shown below in FIG. 6, the structure of the finger-wearing electronic device (103) can be formed more easily. A temperature sensor (325) having a structure in which the second part (620) is partially covered by the electrode (630) shown below in FIG. 6 may have a structure in which the assembly of the second part (620) and the electrode (630) is simple compared to the temperature sensor (325) shown above in FIG. 6.

[0137] A portion of the temperature sensor (325) may be visually exposed through a portion of the first surface (301). For example, said portion may include an electrode (630). For example, by exposing said portion of the temperature sensor (325) (or the electrode (630)) through the first surface (301), said portion may come into contact with the user's finger when worn by the user.

[0138] As a non-limiting example, the finger-wearing electronic device (103) may use the electrode (630) of the temperature sensor (325), which is visually exposed through a portion of the first surface (301), as an electrode sensor. For example, the electrode (630) of the temperature sensor (325) may be referred to as an internal sensor. In other words, the finger-wearing electronic device (103) may identify electrical characteristics based on sensing data obtained using the electrode (630). Accordingly, the finger-wearing electronic device (103) may identify the positional relationship between the user's finger and water. The electrode (630) of the temperature sensor (325) may be an example of the electrode sensor (221) of at least one sensor (220) of FIG. 2.

[0139] In FIGS. 3a through 6, examples of the structure of a finger-wearing electronic device (103) and at least one sensor (220) included in the finger-wearing electronic device (103) are described. In FIG. 7 below, an example of a method is described in which the finger-wearing electronic device (103) identifies a positional relationship regarding the finger of a user wearing the finger-wearing electronic device (103) and provides a notification based on sensing data (or data) obtained using at least one sensor (220).

[0140] FIG. 7 illustrates an example of a flow of operations for a finger-worn electronic device to detect that it is located in water, acquire a value indicating moisture, and provide a notification.

[0141] At least some of the above methods of FIG. 7 may be performed by the finger-wearing electronic device (103) of FIG. 2. For example, at least some of the above methods may be controlled by at least one processor (210) of the finger-wearing electronic device (103). In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0142] In operation (700), at least one processor (210) can detect that it is worn on a user's finger. For example, at least one processor (210) can detect that the finger-wearing electronic device (103) is worn on a part of the user's body (or finger). As an example without limitation, at least one processor (210) can detect the wearing of the finger-wearing electronic device (103) using data obtained using at least one sensor (220). The data obtained using at least one sensor (220) may include at least one of data obtained using an electrode sensor (221), data obtained using an optical sensor (223), data obtained using a temperature sensor (225), or data obtained using a motion sensor.

[0143] In operation (705), at least one processor (210) can identify the location of the finger-wearing electronic device (103) in water based on resistance data. For example, at least one processor (210) can identify whether the finger-wearing electronic device (103) is located in water or out of water based on the resistance data obtained using at least one sensor (220). For example, the resistance data can be obtained using the electrode sensor (221) of at least one sensor (220). At least one processor (210) can perform a comparison between the resistance identified based on the resistance data and at least one reference resistance. For example, based on the result of the comparison, at least one processor (210) can identify the location of the finger-wearing electronic device (103) in water. Specific details regarding operation (705) may be referenced below in FIG. 8.

[0144] As a non-limiting example, the data regarding the resistance may be obtained using internal electrodes of the electrode sensor (221) (e.g., the first electrode (421) and the second electrode (422) of the second sensor (420) of the sensor package (370). As a non-limiting example, the data regarding the resistance may be obtained using one internal electrode of the electrode sensor (221) (e.g., the first electrode (421) and the second electrode (422) of the second sensor (420) of the sensor package (370) or the electrode (630) of the temperature sensor (325)) and one external electrode (e.g., electrode (321-1) or electrode (321-2)). As a non-limiting example, the data regarding the resistance may be obtained using external electrodes of the electrode sensor (221) (e.g., electrode (321-1) and electrode (321-2)).

[0145] In the above example, the case in which whether the finger-wearing electronic device (103) is located in water or out of water is identified based on data regarding the resistance obtained using the electrode sensor (221) is described, but the present disclosure is not limited thereto. For example, the finger-wearing electronic device (103) may obtain data regarding the optical characteristics (e.g., wavelength) of light using the optical sensor (223) and identify whether the finger-wearing electronic device (103) is located in water or out of water based on said data. Or, for example, the finger-wearing electronic device (103) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on data obtained using the display (260) (or touch panel). Alternatively, for example, the finger-wearing electronic device (103) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on data regarding the characteristics of the vibration of the haptic sensor being transmitted to the microphone (or VPU). Alternatively, for example, the finger-wearing electronic device (103) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on data regarding electrical characteristics obtained using an electrode for wired charging (e.g., electrode (333) in FIG. 3b). Alternatively, for example, the finger-wearing electronic device (103) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on data regarding the characteristics of a signal (e.g., frequency, amplitude) obtained using an ultrasonic sensor included in at least one sensor (220).

[0146] In operation (710), at least one processor (210) may provide a notification based on a value indicating moisture. For example, at least one processor (210) may obtain the value indicating moisture if the finger-wearing electronic device (103), identified as being located in water, is located out of water for a reference time from the point in time when it is identified that the finger-wearing electronic device (103) is located out of water. For example, the value indicating moisture of the user's finger may be obtained based on data obtained using at least one sensor (220). For example, the value indicating moisture may be identified using wavelengths (e.g., two wavelengths) obtained using an optical sensor (223) or by using a change in capacitance using an electrode sensor (221).

[0147] For example, at least one processor (210) may perform a comparison between a value indicating the moisture and at least one reference value. For example, at least one processor (210) may provide a notification based on the result of the comparison. For example, the notification may be displayed via a display (260) or via an external electronic device (e.g., electronic device (101) or wrist-worn electronic device (105)) connected to a finger-worn electronic device (103). Alternatively, for example, the notification may be provided via auditory information (e.g., sound) or tactile information (e.g., vibration) as well as visual information. Specific details regarding the operation (710) may be referenced below in FIG. 9.

[0148] In operation (715), at least one processor (210) can provide a notification indicating the result of at least one action performed by the user regarding water.

[0149] For example, at least one processor (210) can identify the at least one action by using information indicating the location of the user's finger (or finger-wearing electronic device (103)) and water. For example, the at least one action may include hand washing, water sports, or household activities (or work).

[0150] In a non-limiting example, at least one processor (210) can recognize that a user performs a hand-rubbing motion using data obtained through a motion sensor, recognize the sound of flowing water using data obtained through a microphone, and identify (or recognize) the at least one motion as hand washing with flowing water when the length of time (or period of submersion) of the finger-wearing electronic device (103) being placed in water is relatively short.

[0151] In a non-limiting example, at least one processor (210) can recognize that a user performs a hand-rubbing motion using data obtained through a motion sensor, recognize the sound of water falling instead of the sound of flowing water using data obtained through a microphone, and identify (or recognize) the at least one motion as hand washing in standing water when the length of time (or period of submersion) of the finger-wearing electronic device (103) being placed in water is relatively long.

[0152] As a non-limiting example, at least one processor (210) can recognize that the user's hand is rotated using data obtained using a motion sensor, and when the finger-wearing electronic device (103) is periodically positioned in water, the at least one motion can be identified (or recognized) as swimming.

[0153] As a non-limiting example, at least one processor (210) may recognize the at least one action as a water sport upon receiving input from a user instructing to perform a water sport (e.g., snorkeling, diving).

[0154] As an example not limited to, at least one processor (210) can identify (or recognize) the at least one action as a household activity (e.g., laundry, dishwashing) or work when the user's hand moves in the water while the finger-wearing electronic device (103) is placed in the water for a long time (e.g., 5 minutes) or longer, and the area in which the user's hand moves is within a relatively narrow range.

[0155] Alternatively, for example, at least one processor (210) may provide information indicating the location of the user's finger (or finger-wearing electronic device (103)) and water to a trained model (or machine learning) running on the finger-wearing electronic device (103), and obtain (or generate) the at least one action (or result according to the at least one action) from the trained model.

[0156] Identifying the above at least one operation may be performed prior to operation (715), prior to operation (710), or while performing operation (705). When recognizing the above at least one operation as described above, the temperature of the finger wearing the finger-wearing electronic device (103) or the water temperature may be further considered. In the case of a temperature sensor (225) that measures temperature based on contact, a certain amount of time is required for thermal equilibrium, and the temperature sensor (225) that measures temperature based on contact may obtain valid data when the finger-wearing electronic device (103) is placed in water for more than the said certain amount of time.

[0157] For example, the result may include at least one of the user’s water exercise information, guide information for the user’s hand washing, or record information for the user’s hand care. For example, at least one processor (210) may provide a notification indicating the result. For example, the notification indicating the result may be provided immediately (e.g., instance notification) before providing the notification in the operation (710), or it may be provided after data for a certain period (e.g., day, week, or month) has been collected (or stored). Specific details regarding the actions performed based on the trained model of the operation (715) may be referenced below in FIG. 10.

[0158] FIG. 8 illustrates an example of a motion flow for detecting that a finger-worn electronic device is located in water.

[0159] At least some of the above methods of FIG. 8 may be performed by the finger-wearing electronic device (103) of FIG. 2. For example, at least some of the above methods may be controlled by at least one processor (210) of the finger-wearing electronic device (103). In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. FIG. 8 illustrates examples of specific operations of the operation (705) of FIG. 7.

[0160] In operation (800), at least one processor (210) can obtain data regarding resistance using electrodes. For example, at least one processor (210) can obtain data regarding resistance using electrodes included in the electrode sensor (221) among at least one sensor (220). In the above example, data regarding resistance is exemplified as being obtained, but the present disclosure is not limited thereto. For example, the data regarding resistance may be referenced as data regarding electrical characteristics (e.g., impedance, voltage, capacitance). For example, the resistance may be calculated based on a change (or amount of change) in electrical characteristics.

[0161] As a non-limiting example, the electrodes used to obtain data regarding the resistance may include internal electrodes of the electrode sensor (221) (e.g., the first electrode (421) and the second electrode (422) of the second sensor (420) of the sensor package (370). Or, as a non-limiting example, the electrodes used to obtain data regarding the resistance may include one internal electrode of the electrode sensor (221) (e.g., the first electrode (421) and the second electrode (422) of the second sensor (420) of the sensor package (370) or the electrode (630) of the temperature sensor (325)) and one external electrode (e.g., electrode (321-1) or electrode (321-2)). Or, as a non-limiting example, the electrodes used to obtain data regarding the resistance may include external electrodes of the electrode sensor (221) (e.g., electrode (321-1) and electrode (321-2)).

[0162] In operation (805), at least one processor (210) can determine whether the resistance exceeds a reference resistance. For example, at least one processor (210) can determine whether the resistance exceeds the reference resistance based on data regarding the resistance. The reference resistance may represent a magnitude of resistance for distinguishing whether the finger-wearing electronic device (103) is located in water or out of water.

[0163] In operation (805), at least one processor (210) may perform operation (810) when the resistance exceeds the reference resistance. Alternatively, in operation (805), at least one processor (210) may perform operation (815) when the resistance is less than or equal to the reference resistance.

[0164] In the above example, it is described as comparing one reference resistor with the resistor, but the present disclosure is not limited thereto. For example, the resistor may be compared with two reference resistors. For example, at least one processor (210) may perform an operation (810) if the resistor exceeds a first reference resistor. Alternatively, at least one processor (210) may perform an operation (815) if the resistor is less than or equal to a second reference resistor that is less than the first reference resistor.

[0165] In operation (810), at least one processor (210) can identify that the finger-wearing electronic device (103) is located in water. For example, at least one processor (210) can identify that the finger-wearing electronic device (103) is located in water by determining that the resistance exceeds the reference resistance.

[0166] In operation (815), at least one processor (210) can identify that the finger-wearing electronic device (103) is located out of water. For example, at least one processor (210) can identify that the finger-wearing electronic device (103) is located out of water by determining that the resistance is less than or equal to the reference resistance.

[0167] Although not illustrated in FIG. 8, at least one processor (210) may generate information indicating that the finger-wearing electronic device (103) is located in water and / or information indicating that the finger-wearing electronic device (103) is located out of water. For example, at least one processor (210) may provide (or transmit) information indicating that the finger-wearing electronic device (103) is located in water and / or information indicating that the finger-wearing electronic device (103) is located out of water to a trained model. For example, the trained model may be learned to identify at least one action performed by a user regarding water and to generate a result according to said at least one action.

[0168] In FIG. 8, a case is illustrated in which at least one processor (210) identifies the location of water in the finger-wearing electronic device (103) based on a comparison of the resistance and the reference resistance, but the present disclosure is not limited thereto. For example, at least one processor (210) may identify the location of water in the finger-wearing electronic device (103) by further using other data obtained using another sensor of at least one sensor (220).

[0169] For example, the other data may include data regarding the optical properties of light (e.g., wavelength) obtained using an optical sensor (223). For example, at least one processor (210) may identify a change (or amount of change) in optical properties based on data regarding the optical properties of light obtained using the optical sensor (223). At least one processor (210) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on a comparison between a value calculated based on the change and a reference value.

[0170] Alternatively, for example, the other data may include data obtained using a display (260) (or a touch panel). For example, at least one processor (210) may identify a change (or amount of change) in electrical characteristics based on data regarding electrical characteristics obtained using the display (260). At least one processor (210) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on a comparison between a value calculated based on the change and a reference value.

[0171] Alternatively, for example, the other data may include data regarding the characteristics of how the vibration of the haptic sensor is transmitted to the microphone (or VPU). For example, at least one processor (210) may identify a change (or amount of change) in the vibration (or waveform) based on data regarding the vibration obtained using the display (260). At least one processor (210) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on a comparison between a value calculated based on the change and a reference value.

[0172] Alternatively, for example, the other data may include data regarding electrical characteristics obtained using an electrode for wired charging (e.g., electrode (333) in FIG. 3b). For example, at least one processor (210) may identify a change (or amount of change) in electrical characteristics based on data regarding electrical characteristics obtained using an electrode for wired charging (e.g., electrode (333) in FIG. 3b). At least one processor (210) may identify whether the finger-worn electronic device (103) is located in water or out of water based on a comparison between a value calculated based on the change and a reference value.

[0173] Alternatively, for example, the other data may include data regarding the characteristics (e.g., frequency, amplitude) of a signal obtained using an ultrasonic sensor. For example, at least one processor (210) may identify a change (or amount of change) in the characteristics of the signal based on the data regarding the signal obtained using an ultrasonic sensor. At least one processor (210) may identify whether the finger-wearing electronic device (103) is located in water or out of water based on a comparison between a value calculated based on the change and a reference value.

[0174] FIG. 9 illustrates an example of a flow of operation for a method of obtaining a value indicating the moisture of a finger after a finger-worn electronic device is placed out of water, and providing a notification based on the value.

[0175] At least some of the above methods of FIG. 9 may be performed by the finger-wearing electronic device (103) of FIG. 2. For example, at least some of the above methods may be controlled by at least one processor (210) of the finger-wearing electronic device (103). In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. FIG. 9 illustrates examples of specific operations of the operation (710) of FIG. 7.

[0176] Although not illustrated in FIG. 9, at least one processor (210) can identify that the finger-wearing electronic device (103) is located in water according to the operation (805) and operation (810) of FIG. 8. After identifying that the finger-wearing electronic device (103) is located in water (or while the finger-wearing electronic device (103) is located in water), at least one processor (210) can acquire data according to the operation (800) of FIG. 8.

[0177] In operation (900), at least one processor (210) can identify the time when the finger-wearing electronic device (103) is located out of water. At least one processor (210) can identify that the finger-wearing electronic device (103) is located out of water based on data obtained after identifying that the finger-wearing electronic device (103) is located in water. In other words, at least one processor (210) can identify that the finger-wearing electronic device (103) has moved from inside water to being located out of water. The movement of the finger-wearing electronic device (103) may be caused by the movement of the finger of the user wearing the finger-wearing electronic device (103).

[0178] At least one processor (210) can identify (or store, cache) the time when the finger-wearing electronic device (103) located in water comes out of the water. After identifying the time, at least one processor (210) can identify the location of the finger-wearing electronic device (103) in the water by repeatedly (or periodically) performing the method of FIG. 8.

[0179] In operation (905), at least one processor (210) can determine whether the finger-wearing electronic device (103) is positioned out of water for a reference time from the time. For example, the reference time may represent the time for the moisture (or residual moisture) of the finger to dry (or be removed) to a certain level after the finger-wearing electronic device (103) is moved out of water.

[0180] As a non-limiting example, at least one processor (210) may determine whether the finger-wearing electronic device (103) is located out of water during the reference time from the time based on other data obtained after identifying the time. The other data may be data obtained after identifying the time among the data obtained according to the operation (800) of FIG. 8.

[0181] In operation (905), at least one processor (210) may perform operation (915) if the finger-wearing electronic device (103) is positioned out of water during the reference time from the said time (or during a time of length exceeding the reference time). In operation (905), at least one processor (210) may perform operation (910) if the finger-wearing electronic device (103) is positioned back in water within the reference time from the said time.

[0182] In operation (910), at least one processor (210) can identify the location of the finger-wearing electronic device (103) in water based on resistance data. For example, if at least one processor (210) determines that the finger-wearing electronic device (103) is again located in water within the reference time from the time, it can identify the location of the finger-wearing electronic device (103) in water based on resistance data. Operation (910) may substantially correspond to operation (705) of FIG. 7 (or the method of FIG. 8). Specific details regarding operation (910) may be referenced to operation (705) of FIG. 7 and the method of FIG. 8.

[0183] In operation (915), at least one processor (210) may obtain a value indicating the moisture of the finger. For example, at least one processor (210) may obtain the value indicating the moisture of the finger when determining that the finger-wearing electronic device (103) is positioned out of water for a reference time from the time (or for a length of time exceeding the reference time). For example, the value indicating the moisture of the finger may indicate skin hydration. As an example without limitation, the value may be obtained based on data obtained using at least one sensor (220). For example, the value indicating the moisture may be identified using wavelengths (e.g., two wavelengths) obtained using an optical sensor (223) or identified using a change in capacitance using an electrode sensor (221).

[0184] In operation (920), at least one processor (210) can determine whether the value is less than a first reference value. For example, the first reference value can be used to determine whether the finger is dry with low moisture (or residual moisture) of the finger.

[0185] In operation (920), at least one processor (210) may perform operation (925) as it determines that the value is less than the first reference value. In operation (920), at least one processor (210) may perform operation (930) as it determines that the value is greater than or equal to the first reference value.

[0186] In operation (925), at least one processor (210) may provide a first notification. For example, at least one processor (210) may recognize that the user's finger is dry as it determines that the value is less than the first reference value. For example, at least one processor (210) may provide the first notification guiding the user that there is a lack of moisture (or residual moisture) in the finger as it determines that the value is less than the first reference value.

[0187] For example, the first notification may be provided based on an output device. As an example without limitation, at least one processor (210) may display the first notification, which is a visual object to guide the user that the finger is dehydrated, through a display (260). As an example without limitation, at least one processor (210) may output the first notification, which is sound information to guide the user that the finger is dehydrated, through a speaker. As an example without limitation, at least one processor (210) may output the first notification, which is haptic feedback to guide the user that the finger is dehydrated, through an actuator. As an example without limitation, the first notification may include information to induce the user to use hand cream.

[0188] In operation (930), at least one processor (210) can determine whether the value exceeds the second reference value. For example, if the value is greater than or equal to the first reference value, at least one processor (210) can determine whether the value exceeds the second reference value which exceeds the first reference value.

[0189] In operation (930), at least one processor (210) may perform operation (935) as it determines that the value exceeds the second reference value. In operation (930), at least one processor (210) may perform operation (940) as it determines that the value is less than or equal to the second reference value (and greater than or equal to the first reference value).

[0190] In operation (935), at least one processor (210) may provide a second notification. For example, at least one processor (210) may recognize that the user's finger is wet as it determines that the value exceeds the second reference value. For example, at least one processor (210) may provide the second notification guiding the user to unworn the finger-wearing electronic device (103) as it determines that the value exceeds the second reference value.

[0191] For example, the second notification may be provided based on an output device. In an example, without limitation, at least one processor (210) may display the second notification, which is a visual object to guide the user to unworn the finger-worn electronic device (103), through a display (260). In an example, without limitation, at least one processor (210) may output the second notification, which is acoustic information to guide the user to unworn the finger-worn electronic device (103), through a speaker. In an example, without limitation, at least one processor (210) may output the second notification, which is haptic feedback to guide the user to unworn the finger-worn electronic device (103), through an actuator. In an example, without limitation, the second notification may include information to indicate drying after unworn the finger-worn electronic device (103). For example, the second notification may include information for notifying of the drying of the finger-wearing electronic device (103) and / or the drying of the finger (or hand) wearing the finger-wearing electronic device (103).

[0192] In operation (940), at least one processor (210) may update data to provide a third notification. For example, at least one processor (210) may update the trained model with data to provide the third notification indicating the result of at least one action performed by the user regarding water. Updating the data to provide the third notification to the trained model may include transmitting and storing the data to provide the third notification to the trained model.

[0193] As a non-limiting example, at least one processor (210) may perform an operation (940) after providing the first notification. As a non-limiting example, at least one processor (210) may perform an operation (940) after providing the second notification. As a non-limiting example, at least one processor (210) may recognize that the moisture of the user's finger is at an appropriate level when the value is less than or equal to the second reference value and greater than or equal to the first reference value, and may perform an operation (940).

[0194] FIG. 10 illustrates an example of a flow of operations for obtaining a result based on at least one action performed by a user regarding water based on a trained model, and providing a notification indicating the result.

[0195] At least some of the above methods of FIG. 10 may be performed by the finger-wearing electronic device (103) of FIG. 2. For example, at least some of the above methods may be controlled by at least one processor (210) of the finger-wearing electronic device (103). In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. FIG. 10 illustrates examples of specific operations of the operation (715) of FIG. 7.

[0196] In operation (1000), at least one processor (210) may provide information to a trained model indicating the position of the finger-wearing electronic device (103) in water. For example, at least one processor (210) may generate information indicating that the finger-wearing electronic device (103) is located in water and / or information indicating that the finger-wearing electronic device (103) is located out of water, depending on operation (810) and / or operation (815) of FIG. 8. For example, at least one processor (210) may provide (or transmit) to the trained model information indicating that the finger-wearing electronic device (103) is located in water and / or information indicating that the finger-wearing electronic device (103) is located out of water. For example, the trained model may be trained to identify at least one action performed by a user regarding water and to generate a result according to said at least one action.

[0197] In FIG. 10, the information indicating the position of the finger-worn electronic device (103) regarding water is shown to be provided to the trained model, but the present disclosure is not limited thereto. For example, at least one processor (210) may further provide the trained model with additional data obtained using at least one sensor (220) while the user performs at least one action regarding water. As an example without limitation, the additional data may include sensing data obtained through a motion sensor (e.g., an accelerometer or a gyroscope). As an example without limitation, the additional data may include data obtained through a microphone (or VPU).

[0198] As an example without limitation, providing the information and additional data to the trained model may be performed for a specific period of time. For example, the specific period of time may be pre-set by the user. As an example without limitation, the length of the specific period of time may be a time length corresponding to one operation, one day, one week, or one month.

[0199] As an example without limitation, the information and additional data may be used to generate statistics aggregated according to one or more conditions. For example, the one or more conditions may include the time and frequency of actions performed while the information and additional data are acquired (e.g., the total time and number of times hands are washed per day). For example, the one or more conditions may include the frequency and duration of the user's hand being placed in water during actions performed while the information and additional data are acquired. For example, the one or more conditions may include the water temperature (or average water temperature) of the actions performed while the information and additional data are acquired, the temperature of the hand (or fingers) before the actions are performed, or the temperature of the hand (or fingers) after the actions are performed. For example, the one or more conditions may include the skin hydration level before the actions performed while the information and additional data are acquired and the skin hydration level after the actions are performed. For example, one or more of the above conditions may include a time during which the residual moisture of the finger-wearing electronic device (103) is maintained at a certain level or higher after the operation performed while the information and the additional data are acquired is performed.

[0200] In operation (1005), at least one processor (210) can obtain a result according to at least one action performed by the user regarding water from the trained model.

[0201] For example, at least one processor (210) can identify the at least one action performed by the user with respect to water by using the trained model by providing the information (and the additional data) to the trained model. For example, at least one processor (210) can output information regarding the at least one action identified (or determined, recognized) from the trained model. For example, the at least one action may include hand washing, water sports, and household activities. As an example without limitation, at least one processor (210) may also identify an action different from the at least one action (or an action unrelated to water) (e.g., walking, running) by providing the information (and the additional data) to the trained model.

[0202] For example, at least one processor (210) may generate a result according to the at least one action using the trained model. As an example without limitation, the trained model may generate the result by further using the at least one action and other additional data (e.g., water temperature, skin temperature). The result according to the at least one action may include at least one of record information regarding the user’s water sports (or automatic exercise records), guide information for the user’s hand washing, or record information for the user’s hand care. As an example without limitation, if the at least one action is the water sports, the result may include record information regarding the user’s water sports (or automatic exercise records). As an example without limitation, if the at least one action is hand washing, the result may include guide information for the user’s hand washing. As an example without limitation, if the at least one action is the household activity, the result may include record information for the user’s hand care.

[0203] In operation (1010), at least one processor (210) may provide a notification indicating the result. For example, the notification may be referred to as the third notification of operation (940).

[0204] As a non-limiting example, at least one processor (210) may provide the notification indicating the result while performing the operation (915). In other words, at least one processor (210) may provide the notification indicating the result when the finger-wearing electronic device (103) is located out of the water during the reference time from the time the finger-wearing electronic device (103) located in the water comes out of the water. The notification provided therein may be referred to as an instance notification. For example, the instance notification may include the notification indicating the result based on data (or statistics) of a relatively short period (e.g., one hand wash, one exercise, one virtual activity).

[0205] As a non-limiting example, at least one processor (210) may provide the notification indicating the result after updating it based on data (or statistics) of a certain period. In other words, at least one processor (210) may update the result by updating it based on data of the certain period (e.g., day, week, or month). The certain period may represent a relatively long period. At least one processor (210) may provide the notification indicating the updated result. Providing the notification indicating the updated result may be referred to as providing a hand health service.

[0206] As an example not limited to, the hand health service may include hand washing guidance. For example, to provide the hand washing guidance, at least one processor (210) may determine how often the user has washed their hands and how correctly they have washed their hands. As an example not suggested, at least one processor (210) may provide a notification suggesting hand washing if the user has not washed their hands for a certain period of time or if foreign matter is present on the optical sensor and electrode sensor.

[0207] As a non-limiting example, the hand health service may include a skin moisturization notification. For example, for the skin moisturization notification, at least one processor (210) may notify the need for skin moisturization by comparing the skin oil / moisture status and balance of the hand (or finger) and the condition of the skin before and after the operation regarding water. Even if the current oil / moisture and balance of the skin is good, at least one processor (210) may provide a notification to maintain a healthy state by notifying skin moisturization, taking into account the surrounding environment and the temperature of the skin and the water temperature, if the time of underwater activity is above a certain level.

[0208] As an example not limited to, the hand health service may include a notification of the need to dry the hands. For example, for the hand drying notification, at least one processor (210) may notify of the need to dry the skin if the user's hand (or finger) (or finger-worn electronic device (103)) has been submerged in water for a long time (or has been placed in water) or if residual moisture is maintained in the finger-worn electronic device (103) for a certain period of time or longer. At least one processor (210) may notify without a separate prediction if the waiting time to measure the oil / moisture level of the skin during the process of generating the statistics based on data collection exceeds a certain period of time. Accordingly, at least one processor (210) can prevent skin inflammation problems caused by long-term use of the finger-worn electronic device (103) in advance.

[0209] As a non-limiting example, among the hand health services, the skin moisturization notification and the hand dryness need notification may be provided via instance notification. Each of the skin moisturization notification and the hand dryness need notification may be provided in the first notification and the second notification provided in the operation (925) and operation (935) of FIG. 9. However, the present disclosure is not limited thereto.

[0210] As an example not limited to, the hand health service may include an appropriate water temperature guide. For example, for the appropriate water temperature guide, at least one processor (210) may provide guidance on an appropriate water temperature based on the external temperature, the temperature of the hand (or fingers), and changes in temperature. For example, since washing hands with relatively cold water on a cold and dry day can cause frostbite or dryness, at least one processor (210) may provide guidance on washing hands with relatively lukewarm water. For example, if the water temperature measured using a temperature sensor (225) is above a certain temperature (e.g., 42°C), since the user may feel hot when water of that temperature comes into contact with the user's hand, at least one processor (210) may provide a notification to warn the user. Alternatively, for example, when the user takes a bath, at least one processor (210) can measure the water temperature for the bath using a temperature sensor (225) and indicate that the water temperature is an appropriate temperature for the bath.

[0211] As an example not limited to, the hand health service may include an eczema incidence rate prediction. For the eczema incidence rate prediction, at least one processor (210) may provide a notification regarding the eczema incidence rate to the user by predicting the eczema incidence rate when the user has a habit of performing virtual activities (e.g., washing dishes, doing laundry) without wearing gloves, or when the user wears gloves for a long time and does not remove them, thereby exposing the hands to a humid environment for a long time. When predicting the eczema incidence rate, the time spent submerged in water for each water-related action and the time during which residual moisture on the hand (or finger, finger-worn electronic device (103)) is maintained above a certain level after the water-related action may be taken into consideration.

[0212] As an example without limitation, the hand health service may include providing comprehensive statistics related to water contact. The provision of comprehensive statistics may be performed using the statistics generated using the information and the additional data, or using results predicted by the trained model based on the provision of the information and the additional data.

[0213] In the examples of FIGS. 9 and 10, cases are illustrated in which at least one processor (210) (or, finger-wearing electronic device (103)) directly provides a notification (e.g., the first notification, the second notification, and the third notification), but the present disclosure is not limited thereto. For example, at least one processor (210) may cause the external electronic device to provide the notification by providing information for the notification to the external electronic device. Examples of the notification provided by the external electronic device may be referenced below in FIGS. 11a and 11b.

[0214] FIG. 11a illustrates an example of a notification indicating the result of at least one action performed by a user regarding water, displayed on an electronic device connected to a finger-wearing electronic device.

[0215] FIG. 11a illustrates an example of a notification, which is visual information displayed on an electronic device (101) connected to a finger-wearing electronic device (103). For example, the electronic device (101) may be an example of an external electronic device connected to the finger-wearing electronic device (103).

[0216] The electronic device (101) may receive information for the notification from the finger-wearing electronic device (103). As an example, without limitation, the electronic device (101) may also receive other information for the notification from other wearable devices (e.g., wrist-wearing electronic device (105)) in addition to the finger-wearing electronic device (103). Specific details regarding this may be referenced in FIG. 12b below.

[0217] The electronic device (101) can generate a notification using the received information. In FIG. 11a, an example of the notification being visual information (or a visual object) is illustrated, but the present disclosure is not limited thereto. For example, the notification may include auditory information or tactile information.

[0218] As an example without limitation, the above notification may be displayed through a screen (or representation, UI (user interface)) of a software application for health management. For example, an electronic device (101) may run the software application. The electronic device (101) may display a screen (1110) based on running the software application. For example, the screen (1110) may be a screen for providing information for hand health.

[0219] As a non-limiting example, the screen (1110) may include a plurality of visual objects (1120, 1125, 11230, 1135) which are information for hand health. For example, the visual object (1120) may include a graph indicating a hand health score. For example, the hand health score may be information that scores hand health over a week. For example, the visual object (1125) may include text indicating the hand health score and the moisture status of the user's hand (or finger) for a selected date (1121) within the week. Although not illustrated in FIG. 11a, the visual object (1125) may further include sentences (or paragraphs) containing more detailed information.

[0220] For example, the visual object (1130) may include graphs indicating scores for factors affecting the hand health score. For example, the factors may include hand washing frequency, hand washing according to the correct method, time the hand is placed in water other than during hand washing, skin hydration, and water temperature (or external temperature). For example, the visual object (1135) may include text indicating water temperature by action.

[0221] As a non-limiting example, the electronic device (101) may display one of the menus (1151, 1152, 1153, 1154) exemplified on the screen (1150). For example, each of the menus (1151, 1152, 1153, 1154) may be displayed as a pop-up on a different screen (e.g., a home screen). Or, for example, the menus (1151, 1152, 1153, 1154) exemplified on the screen (1150) may be displayed within the screen (1110).

[0222] For example, menu (1151) may include text indicating that the user's hand moisture is low and moisturization is needed. For example, menu (1152) may include text indicating that the user's hand moisture is high and drying is needed. For example, menu (1153) may include text indicating that periodic hand washing is needed. For example, menu (1154) may include text indicating that water temperature is adjusted (e.g., increased water temperature). Although the hand-shaped icons included in each of the menus (1151, 1152, 1153, 1154) of FIG. 11a are exemplified as being identical, the present disclosure is not limited thereto. For example, menus (1151, 1152, 1153, 1154) may include different icons. For example, menu (1151) may include an icon indicating that moisturization is needed. For example, the menu (1151) may include an icon indicating that drying is required.

[0223] FIG. 11b illustrates an example of a notification indicating the result of at least one action performed by a user regarding water, displayed on a wrist-worn electronic device connected to a finger-worn electronic device.

[0224] FIG. 11b illustrates an example of a notification, which is visual information displayed on a wrist-worn electronic device (105) connected to a finger-worn electronic device (103). For example, the wrist-worn electronic device (105) may be an example of an external electronic device connected to the finger-worn electronic device (103).

[0225] The wrist-worn electronic device (105) can receive information for the notification from the finger-worn electronic device (103). Specific details regarding this may be referenced in FIG. 12a below.

[0226] A wrist-worn electronic device (105) can generate a notification using the received information. In FIG. 11b, an example of the notification being visual information (or a visual object) is illustrated, but the present disclosure is not limited thereto. For example, the notification may include auditory information or tactile information.

[0227] As an example without limitation, the above notification may be displayed through a screen (or representation, UI (user interface)) of a software application for health management. For example, a wrist-worn electronic device (105) may run the software application. The wrist-worn electronic device (105) may display a screen (1160) or a screen (1170) based on running the software application.

[0228] As a non-limiting example, the screen (1160) may include a notification to guide the user to rest when the user's action is water sports (e.g., swimming). As a non-limiting example, the screen (1170) may include a notification to guide the user to an appropriate bathing method when the user's action is bathing. For example, when the user is bathing, the finger-worn electronic device (103) may measure the water temperature for bathing using a temperature sensor (225) and provide guidance that the water temperature is an appropriate temperature for bathing.

[0229] FIG. 12a illustrates an example of signal flow between a finger-worn electronic device and a wrist-worn electronic device for acquiring data related to actions performed by a user regarding water and providing notifications.

[0230] FIG. 12a illustrates an example of a signal flow between a finger-wearing electronic device (103) and a wrist-wearing electronic device (105) for providing hand health services on the wrist-wearing electronic device (105) based on data related to actions performed by the user regarding water. Although not illustrated in FIG. 12a, the finger-wearing electronic device (103) and the wrist-wearing electronic device (105) may establish a connection for communication. After the connection is established, the wrist-wearing electronic device (105) may detect that the finger-wearing electronic device (103) is worn on the user's finger.

[0231] In operation (1200), the wrist-worn electronic device (105) can detect that the user's finger is positioned in water. For example, the wrist-worn electronic device (105) can detect that the user's finger is positioned in water by using data obtained using at least one sensor included in the wrist-worn electronic device (105). For example, the at least one sensor may include a motion sensor (e.g., accelerometer, gyroscope), a temperature sensor, or a barometric pressure sensor. Alternatively, for example, the wrist-worn electronic device (105) can detect that the user's finger is positioned in water by using data obtained using a microphone (or VPU) included in the wrist-worn electronic device (105).

[0232] In operation (1205), the finger-wearing electronic device (103) can detect that the user's finger is positioned in water. For example, the finger-wearing electronic device (103) can detect that the user's finger is positioned in water according to the method described in FIG. 8. As an example without limitation, the finger-wearing electronic device (103) can acquire resistance data using an electrode sensor (221) and detect that the user's finger is positioned in water based on the acquired resistance data.

[0233] Although not illustrated in FIG. 12a, the finger-wearing electronic device (103) may store data used to detect when the user's finger is positioned in water during operation (1205). By example, without limitation, the stored data may include data representing the movement of the user's finger (or hand) obtained using a motion sensor, data representing sound obtained using a microphone (or VPU), and data representing the temperature of the finger-wearing electronic device (103) or the water obtained using a temperature sensor.

[0234] As a non-limiting example, the data obtained by the wrist-worn electronic device (105) in operation (1200) (or the sensor used to obtain said data) may be different from the data obtained by the finger-worn electronic device (103) in operation (1205) (or the sensor used to obtain said data). By using different sensors, power consumption between the wrist-worn electronic device (105) and the finger-worn electronic device (103) can be reduced.

[0235] As a non-limiting example, data acquired by the wrist-worn electronic device (105) in operation (1200) (or a sensor used to acquire said data) and data acquired by the finger-worn electronic device (103) in operation (1205) (or a sensor used to acquire said data) may be at least partially identical (or overlapped). For example, by using at least partially identical sensors, the accuracy of distinguishing (or identifying) the movements performed by the user's finger in water based on the data acquired by the wrist-worn electronic device (105) and the finger-worn electronic device (103) may be increased.

[0236] In FIG. 12a, the operation (1205) and the operation (1200) are shown to be performed simultaneously, but the present disclosure is not limited thereto. For example, the operation (1205) may be performed first, or the operation (1200) may be performed first.

[0237] In operation (1210), the finger-worn electronic device (103) may transmit the data acquired while positioned in water to the wrist-worn electronic device (105). For example, the data may be acquired while the finger-worn electronic device (103) (or the user's hand or finger) is positioned in water. As an example without limitation, the finger-worn electronic device (103) may perform compression on the data and then transmit the compressed data to the wrist-worn electronic device (105) in order to reduce the amount of data transmitted while positioned in water.

[0238] As an example not limited to, the operation (1210) may be performed upon detecting that the finger-worn electronic device (103) located in water is located out of water. Since communication performance is low while located in water, the transmission of the data may be performed when the finger-worn electronic device (103) is located out of water. In other words, the finger-worn electronic device (103) may refrain from transmitting the data to the wrist-worn electronic device (105) while located in water, and the finger-worn electronic device (103) may transmit the data to the wrist-worn electronic device (105) after the time it is located out of water. Referring to the description below, the data may authorize the wrist-worn electronic device (105) to provide notifications for hand health services (e.g., visual information, auditory information, or tactile information).

[0239] Although not illustrated in FIG. 12a, when the finger-wearing electronic device (103) detects that it is located out of water, it may transmit information indicating that the finger-wearing electronic device (103) (or the user's finger) is located out of water to the wrist-wearing electronic device (105). Accordingly, the wrist-wearing electronic device (105) may stop acquiring data used to detect that it is located in water.

[0240] In operation (1215), the wrist-worn electronic device (105) can perform data integration. For example, the wrist-worn electronic device (105) can perform integration of directly acquired data and data acquired from the finger-worn electronic device (103). This integration can be used to increase the accuracy of distinguishing (or identifying) the actions performed by the user's finger in water.

[0241] In operation (1220), the finger-wearing electronic device (103) can obtain a value indicating moisture. For example, the finger-wearing electronic device (103) can identify the time at which the finger-wearing electronic device (103) is identified as being out of water. The finger-wearing electronic device (103) can identify that the finger-wearing electronic device (103) is out of water based on data obtained after identifying that the finger-wearing electronic device (103) is in water. In other words, the finger-wearing electronic device (103) can identify that the finger-wearing electronic device (103) has moved from inside the water and is now located out of water. The finger-wearing electronic device (103) can determine whether the finger-wearing electronic device (103) is located out of water for a reference time from the said time. For example, the above reference time may represent the time for the moisture (or residual moisture) of the finger to dry (or be removed) to a certain level after the finger-wearing electronic device (103) is moved out of the water.

[0242] In a non-limiting example, the finger-wearing electronic device (103) can obtain the value indicating the moisture of the finger when determining that the finger-wearing electronic device (103) is positioned out of water for a reference time from the time (or for a length of time exceeding the reference time).

[0243] In operation (1225), the finger-wearing electronic device (103) may transmit the value indicating moisture to the wrist-wearing electronic device (105). As an example without limitation, the finger-wearing electronic device (103) may transmit to the wrist-wearing electronic device (105) in response to acquiring the value indicating moisture of the finger.

[0244] In operation (1230), the wrist-worn electronic device (105) may provide a notification. The wrist-worn electronic device (105) may provide the notification upon receiving the value indicating the moisture. In other words, the notification may be provided after the finger has been placed out of the water for a certain period of time or longer.

[0245] As a non-limiting example, a wrist-worn electronic device (105) may generate and provide the notification using data integrated from the action (1215). The notification may indicate at least one action performed by the user in the water and the result of said at least one action. For example, the notification may include at least one of visual information, auditory information, or tactile information. A specific example of a method for providing the notification may be referenced in FIG. 11b.

[0246] FIG. 12b illustrates an example of signal flow between an electronic device, a finger-worn electronic device, and a wrist-worn electronic device for acquiring data related to actions performed by a user regarding water and providing notifications.

[0247] FIG. 12b illustrates an example of signal flow between an electronic device (101), a finger-worn electronic device (103), and a wrist-worn electronic device (105) for providing hand health services in the electronic device (101) based on data related to actions performed by a user regarding water. Although not illustrated in FIG. 12b, the finger-worn electronic device (103) and the electronic device (101) may establish a connection for communication. Additionally, the electronic device (101) and the wrist-worn electronic device (105) may establish a connection for communication. After the connection is established, the electronic device (101) may detect that the finger-worn electronic device (103) is worn on the user's finger and that the wrist-worn electronic device (105) is worn on the user's wrist. In the example of FIG. 12b, unlike FIG. 12a, a connection between the finger-worn electronic device (103) and the wrist-worn electronic device (105) is depicted as not being established, but the present disclosure is not limited thereto. For example, a connection can be established between a finger-worn electronic device (103) and a wrist-worn electronic device (105).

[0248] In operation (1240), the wrist-worn electronic device (105) can detect that the user's finger is positioned in water. For example, the wrist-worn electronic device (105) can detect that the user's finger is positioned in water by using data obtained using at least one sensor included in the wrist-worn electronic device (105). For example, the at least one sensor may include a motion sensor (e.g., accelerometer, gyroscope), a temperature sensor, or a barometric pressure sensor. Alternatively, for example, the wrist-worn electronic device (105) can detect that the user's finger is positioned in water by using data obtained using a microphone (or VPU) included in the wrist-worn electronic device (105).

[0249] In operation (1245), the finger-wearing electronic device (103) can detect that the user's finger is positioned in water. For example, the finger-wearing electronic device (103) can detect that the user's finger is positioned in water according to the method described in FIG. 8. As an example without limitation, the finger-wearing electronic device (103) can acquire resistance data using an electrode sensor (221) and detect that the user's finger is positioned in water based on the acquired resistance data.

[0250] Although not illustrated in FIG. 12b, the finger-wearing electronic device (103) may store data used to detect when the user's finger is positioned in water during operation (1245). As an example without limitation, the stored data may include data representing the movement of the user's finger (or hand) obtained using a motion sensor, data representing sound obtained using a microphone (or VPU), and data representing the temperature of the finger-wearing electronic device (103) or the water obtained using a temperature sensor.

[0251] As a non-limiting example, the data obtained by the wrist-worn electronic device (105) in operation (1240) (or the sensor used to obtain said data) may be different from the data obtained by the finger-worn electronic device (103) in operation (1245) (or the sensor used to obtain said data). By using different sensors, power consumption between the wrist-worn electronic device (105) and the finger-worn electronic device (103) can be reduced.

[0252] As a non-limiting example, data obtained by the wrist-worn electronic device (105) in operation (1240) (or the sensor used to obtain said data) and data obtained by the finger-worn electronic device (103) in operation (1245) (or the sensor used to obtain said data) may be at least partially identical (or overlapped). For example, by using at least partially identical sensors, the accuracy of distinguishing (or identifying) the movements performed by the user's finger in water based on the data obtained by the wrist-worn electronic device (105) and the finger-worn electronic device (103) may be increased.

[0253] In FIG. 12b, the operation (1245) and the operation (1240) are depicted as being performed simultaneously, but the present disclosure is not limited thereto. For example, the operation (1245) may be performed first, or the operation (1240) may be performed first.

[0254] In operation (1250), the wrist-worn electronic device (105) may transmit the data acquired while positioned in water to the electronic device (101). For example, the data may be acquired while the user's hand (or fingers) is positioned in water. As an example without limitation, the wrist-worn electronic device (105) may perform compression on the data and then transmit the compressed data to the electronic device (101) in order to reduce the amount of data transmitted while positioned in water.

[0255] In operation (1255), the finger-wearing electronic device (103) may transmit the data acquired while positioned in water to the electronic device (101). For example, the data may be acquired while the finger-wearing electronic device (103) (or the user's hand or finger) is positioned in water. As an example without limitation, the finger-wearing electronic device (103) may perform compression on the data and then transmit the compressed data to the electronic device (101) in order to reduce the amount of data transmitted while positioned in water.

[0256] As an example not limited to, the operation (1255) may be performed upon detecting that the finger-wearing electronic device (103) located in water is located out of water. Since communication performance is low while located in water, the transmission of the data may be performed when the finger-wearing electronic device (103) is located out of water. In other words, the finger-wearing electronic device (103) may refrain from transmitting the data to the electronic device (101) while located in water, and the finger-wearing electronic device (103) may transmit the data to the electronic device (101) after the time it is located out of water. Referring to the description below, the data may authorize the electronic device (101) to provide a notification for hand health services (e.g., visual information, auditory information, or tactile information).

[0257] Although not illustrated in FIG. 12b, when the finger-wearing electronic device (103) detects that it is located out of water, information indicating that the finger-wearing electronic device (103) (or the user's finger) is located out of water may be transmitted to the electronic device (101). Accordingly, the electronic device (101) may transmit a command to the wrist-wearing electronic device (105) to stop acquiring data used to detect that it is located in water. Accordingly, the wrist-wearing electronic device (105) may stop acquiring data. However, the present disclosure is not limited thereto. For example, when the finger-wearing electronic device (103) detects that it is located out of water, information indicating that the finger-wearing electronic device (103) (or the user's finger) is located out of water may be transmitted directly to the wrist-wearing electronic device (105). Accordingly, the wrist-wearing electronic device (105) may stop acquiring data used to detect that it is located in water.

[0258] In operation (1260), the electronic device (101) can perform data integration. For example, the electronic device (101) can perform integration of data obtained from a wrist-worn electronic device (105) and data obtained from a finger-worn electronic device (103). The integration can be used to increase the accuracy of distinguishing (or identifying) the movements performed by the user's finger in water.

[0259] In operation (1265), the finger-wearing electronic device (103) can obtain a value indicating moisture. For example, the finger-wearing electronic device (103) can identify the time at which the finger-wearing electronic device (103) is identified as being out of water. The finger-wearing electronic device (103) can identify that the finger-wearing electronic device (103) is out of water based on data obtained after identifying that the finger-wearing electronic device (103) is in water. In other words, the finger-wearing electronic device (103) can identify that the finger-wearing electronic device (103) has moved from inside the water and is now located out of water. The finger-wearing electronic device (103) can determine whether the finger-wearing electronic device (103) is located out of water for a reference time from the said time. For example, the above reference time may represent the time for the moisture (or residual moisture) of the finger to dry (or be removed) to a certain level after the finger-wearing electronic device (103) is moved out of the water.

[0260] In a non-limiting example, the finger-wearing electronic device (103) can obtain the value indicating the moisture of the finger when determining that the finger-wearing electronic device (103) is positioned out of water for a reference time from the time (or for a length of time exceeding the reference time).

[0261] In operation (1270), the finger-wearing electronic device (103) may transmit the value indicating moisture to the electronic device (101). As an example without limitation, the finger-wearing electronic device (103) may transmit to the electronic device (101) in response to acquiring the value indicating moisture of the finger.

[0262] In operation (1275), the electronic device (101) may provide a notification. The electronic device (101) may provide the notification upon receiving the value indicating the moisture. In other words, the notification may be provided after the finger has been placed out of the water for a certain period of time or longer.

[0263] As a non-limiting example, the electronic device (101) may generate the notification and provide the notification by using data integrated in the operation (1260). The notification may indicate at least one action performed by the user in the water and the result of said at least one action. For example, the notification may include at least one of visual information, auditory information, or tactile information. A specific example of a method for providing the notification may be referenced in FIG. 11a.

[0264] FIGS. 12a and 12b assume that the wearable devices are different devices (e.g., wrist-worn electronic device (105) and finger-worn electronic device (103)), but the present disclosure is not limited thereto. For example, the present disclosure may be substantially applicable to wearable devices being the same devices (e.g., two finger-worn electronic devices). Additionally, in conjunction with FIG. 1, the present disclosure may be applicable not only to cases where the wearable devices are worn on the same body part (e.g., left arm) (e.g., wrist-worn electronic device (105) is worn on the wrist of the left arm and finger-worn electronic device (105) is worn on the index finger of the left arm), but also to cases where the wearable devices are worn on different body parts (e.g., the wrist of the left arm and the index finger of the right arm).

[0265] FIG. 13 is a block diagram of an electronic device in a network environment according to various embodiments.

[0266] Referring to FIG. 13, in a network environment (1300), an electronic device (1301) may communicate with an electronic device (1302) through a first network (1398) (e.g., a short-range wireless communication network) or with at least one of an electronic device (1304) or a server (1308) through a second network (1399) (e.g., a long-range wireless communication network). According to one embodiment, the electronic device (1301) may communicate with the electronic device (1304) through a server (1308). According to one embodiment, the electronic device (1301) may include a processor (1320), memory (1330), input module (1350), sound output module (1355), display module (1360), audio module (1370), sensor module (1376), interface (1377), connection terminal (1378), haptic module (1379), camera module (1380), power management module (1388), battery (1389), communication module (1390), subscriber identification module (1396), or antenna module (1397). In some embodiments, at least one of these components (e.g., connection terminal (1378)) may be omitted from the electronic device (1301), or one or more other components may be added. In some embodiments, some of these components (e.g., sensor module (1376), camera module (1380), or antenna module (1397)) may be integrated into a single component (e.g., display module (1360)).

[0267] The processor (1320) can, for example, execute software (e.g., program (1340)) to control at least one other component (e.g., hardware or software component) of the electronic device (1301) connected to the processor (1320) and can perform various data processing or operations. According to one embodiment, as at least part of the data processing or operations, the processor (1320) can store commands or data received from other components (e.g., sensor module (1376) or communication module (1390)) in volatile memory (1332), process the commands or data stored in volatile memory (1332), and store the resulting data in non-volatile memory (1334). According to one embodiment, the processor (1320) may include a main processor (1321) (e.g., a central processing unit or an application processor) or an auxiliary processor (1323) that can operate independently or together with it (e.g., a graphics processing unit, a neural processing unit (NPU), an image signal processor, a sensor hub processor, or a communication processor).
