Wearable electronic device and method for detecting changes in finger size using the same

[0001] The embodiments of the present disclosure relate to a wearable electronic device and a method for detecting changes in finger size using the same.

[0002] Various electronic devices such as smartphones, tablet PCs, PMPs (portable multimedia players), PDAs (personal digital assistants), laptop personal computers, and / or wearable electronic devices are becoming widespread.

[0003] For example, a wearable electronic device may include a smart watch or a smart ring. The wearable electronic device may be equipped with various sensors (e.g., motion sensors, biosensors) to obtain information related to the health or exercise of a user wearing the wearable electronic device.

[0004] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art related to the present disclosure.

[0005] While a user is using a wearable electronic device, such as a smart ring, on their finger, the size of the finger may change due to changes in body weight or swelling. Consequently, the user may feel pain in the finger wearing the wearable electronic device.

[0006] A wearable electronic device may require a method to detect or predict changes in the user's finger size due to changes in body weight or edema, thereby inducing the removal of the wearable electronic device.

[0007] A wearable electronic device according to an embodiment of the present disclosure may include a plurality of pressure sensors spaced apart from each other within the internal space of the wearable electronic device. The wearable electronic device may detect the size of a finger by checking whether the difference between a plurality of pressure values ​​obtained from the plurality of pressure sensors falls within a specified range. Additionally, the wearable electronic device may detect the user's activity state (e.g., exercise state) by checking whether the difference between the obtained plurality of pressure values ​​falls within a specified range.

[0008] A wearable electronic device according to an embodiment of the present disclosure may include an opening formed in a part of a housing and a distance measuring sensor disposed in close proximity to the opening. The wearable electronic device may measure the distance between one end of the opening and the other end of the opening using the distance measuring sensor. The wearable electronic device may detect the size of a finger by checking whether the measured distance between one end of the opening and the other end of the opening exceeds a specified distance.

[0072] In one embodiment, the wearable electronic device (200) may include a battery (189) and a substrate (240) disposed in the internal space of a housing (201). In one embodiment, the battery (189) and the substrate (240) may be disposed in directions facing each other. However, this is not limited thereto.

[0073] In one embodiment, the substrate (240) may be positioned in such a way that it is attached to the inner circumference of the housing (201). For example, the substrate (240) may include a flexible printed circuit board (FPCB). For example, the substrate (240) may have a bendability to correspond to the curvature of the wearable electronic device (200) (e.g., an internal curvature corresponding to the opening (2001) of the housing (201).

However, it is not limited thereto. For example, the wearable electronic device (200) may include more than five pressure sensors or fewer than five pressure sensors.

[0123] In one embodiment, a plurality of pressure sensors (410), for example, a first pressure sensor (410a), a second pressure sensor (410b), a third pressure sensor (410c), a fourth pressure sensor (410d), and a fifth pressure sensor (410e), may be spaced apart (e.g., spaced apart or spaced at a certain angle) within the internal space of a housing (401) having a ring shape. In one embodiment, the positions at which each of the plurality of pressure sensors (410), for example, the first pressure sensor (410a), the second pressure sensor (410b), the third pressure sensor (410c), the fourth pressure sensor (410d), and the fifth pressure sensor (410e) is placed may be different.

[0124] For example, each of the plurality of pressure sensors (410), for example, a first pressure sensor (410a), a second pressure sensor (410b), a third pressure sensor (410c), a fourth pressure sensor (410d), and a fifth pressure sensor (410e), may be positioned in close proximity to one of the connector (425), a charging circuit (420), an optical sensor (e.g., a first optical sensor (250a), a second optical sensor (250b), a third optical sensor (250c)), and a battery (189). For example, the first pressure sensor (410a) may be positioned in close proximity to the optical sensor (250b). The second pressure sensor (410b) may be positioned in close proximity to the charging circuit (420). The third pressure sensor (410c) and the fourth pressure sensor (410d) may be positioned in close proximity to the battery (189). The fifth pressure sensor (410e) can be placed close to the connector (425).

[0125] This is not limited to this, and multiple pressure sensors (410) may be arranged to face each other or arranged at an angle of 90 degrees to each other.

[0126] In one embodiment, when the wearable electronic device (200) is worn on a user's finger, a plurality of pressure sensors (410) can detect (or sense) pressure occurring between the user's finger (e.g., bone) placed in the housing (201) and the opening (2001). In one embodiment, the plurality of pressure sensors (410) can measure (or acquire, detect, sense) pressure applied in the direction in which the plurality of pressure sensors (410) are placed, as they are spaced apart in the internal space of the housing (401) which has a ring shape. The plurality of pressure sensors (410) can distinguish between pressure (e.g., force) applied inside (e.g., opening (2001)) of the wearable electronic device (200) or pressure (e.g., force) applied outside of the wearable electronic device (200) by using the measured (or acquired, detected, sensed) pressure data (e.g., pressure values) and changes in the data (e.g., pressure values).

[0127] In one embodiment, pressure (e.g., force) applied inside the wearable electronic device (200) (e.g., opening (2001)) may mean pressure (e.g., force) applied from inside the wearable electronic device (200) (e.g., opening (2001)) to the outside direction (451, 453, 455, 457, 459) of the wearable electronic device (200). When pressure (e.g., force) is applied from inside the wearable electronic device (200) (e.g., opening (2001)) to the outside direction (451, 453, 455, 457, 459) of the wearable electronic device (200), multiple pressure values ​​measured through multiple pressure sensors (410) may have similar values ​​(or changes in similar values). For example, if a user's finger wearing the wearable electronic device (200) swells, the size of the user's finger may be larger than the size of the user's finger before swelling. As the size of the user's finger increases, pressure (e.g., force) may be applied from the inside of the wearable electronic device (200) (e.g., opening (2001)) to the outside direction (451, 453, 455, 457, 459) of the wearable electronic device (200).

[0128] In one embodiment, each of the plurality of pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) can measure a pressure value corresponding to the pressure (e.g., force). When pressure (e.g., force) is applied from the opening (2001) of the wearable electronic device (200) toward the outside direction (451, 453, 455, 457, 459) of the wearable electronic device (200), the pressure values ​​measured through each of the plurality of pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) may have similar values. As the pressure values ​​measured through each of the multiple pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) have similar values, the difference between the multiple pressure values ​​may be within a specified range. If the difference between the multiple pressure values ​​is within a specified range, the wearable electronic device (200) may determine that pressure has occurred due to finger swelling (or edema) with a finger size of the user wearing the wearable electronic device (200).

[0129] In one embodiment, pressure (e.g., force) applied from the outside of the wearable electronic device (200) may mean pressure (e.g., force) applied from the outside of the wearable electronic device (200) in the direction (461, 463) of the inside of the wearable electronic device (200) (e.g., opening (2001)). When pressure (e.g., force) is applied from the outside of the wearable electronic device (200) in the direction (461, 463) of the inside of the wearable electronic device (200) (e.g., opening (2001)), one pressure value (or at least two pressure values) among a plurality of pressure values ​​measured through a plurality of pressure sensors (410) may be different from at least two other pressure values ​​(e.g., at least three other pressure values).

[0130] In FIG. 4 according to one embodiment, the pressure values ​​measured through the first pressure sensor (410a), the second pressure sensor (410b), and the fourth pressure sensor (410d) among the plurality of pressure sensors (410) and the pressure values ​​measured through the second pressure sensor (410b) and the fifth pressure sensor (410e) among the plurality of pressure sensors (410) are described as being different.

[0131] For example, as pressure (e.g., force) is applied from the outside of the wearable electronic device (200) toward the inside of the wearable electronic device (200) (e.g., opening (2001)) (461, 463), the pressure values ​​measured through the first pressure sensor (410a), the second pressure sensor (410b), and the fourth pressure sensor (410d) and the pressure values ​​measured through the second pressure sensor (410b) and the fifth pressure sensor (410e) among the plurality of pressure sensors (410) do not have similar values, so the difference between the plurality of pressure values ​​may not be included within a specified range. If the difference between the plurality of pressure values ​​is not included within a specified range, the wearable electronic device (200) may determine that pressure has been generated by user activity. For example, pressure generated by user activity may include pressure generated by the user's exercise or user input for executing a specific function.

[0163] In one embodiment, the wearable electronic device (200) may be worn on a part of the user's body, for example, a finger. When the wearable electronic device (200) is worn on the user's finger, a part of the finger may come into contact with the inner surface of the housing (201, 401) of the wearable electronic device (200).

[0164] In one embodiment, the processor (350) can compare a plurality of pressure values ​​obtained in operation 910. In operation 915, the processor (350) can determine that pressure corresponding to the finger size of a user wearing the wearable electronic device (200) has occurred if, based on the comparison result, the difference between the plurality of pressure values ​​is included within a specified range.

[0165] In one embodiment, pressure according to the user's finger size may include pressure according to finger swelling (or edema). For example, when the finger swells, the user's finger size may be larger than the user's finger size before swelling. As the user's finger size increases, pressure (e.g., force) may be applied from the inside of the wearable electronic device (200) (e.g., opening (e.g., opening (2001) in FIG. 2 and FIG. 4)) to the outside of the wearable electronic device (200) (e.g., 451, 453, 455, 457, 459 in FIG. 4). In this case, each of the plurality of pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) may measure a pressure value corresponding to the pressure (e.g., force). When pressure (e.g., force) is applied from the inside (e.g., opening (2001)) of the wearable electronic device (200) to the outside direction of the wearable electronic device (200) (e.g., 451, 453, 455, 457, 459 of FIG. 4), the pressure values ​​measured through each of the plurality of pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) may have similar values. As the pressure values ​​measured through each of the multiple pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) have similar values, the difference between the multiple pressure values ​​may be included within a specified range.

[0166] In one embodiment, the processor (350) may determine that pressure due to finger swelling (or edema) has occurred, with the size of the finger of a user wearing the wearable electronic device (200) as the difference between a plurality of pressure values ​​falls within a specified range.

[0167] FIG. 10 is a flowchart illustrating a finger size detection method according to one embodiment of the present disclosure.

[0168] In the following embodiments, each operation of FIG. 10 may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation of FIG. 10 may be changed, and at least two operations may be performed in parallel.

[0169] According to one embodiment, operations 1010 to 1030 of FIG. 10 can be understood as being performed in a processor (e.g., processor (350) of FIG. 3) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4).

[0170] Since the operations 1010 to 1025 of FIG. 10 according to one embodiment are substantially the same as the operations 905 to 915 of FIG. 9 described above, a detailed description thereof may be replaced by the description of FIG. 9.

[0171] In one embodiment, the processor (350) can obtain multiple pressure values ​​through multiple pressure sensors (e.g., pressure sensor (331) of FIG. 3, multiple pressure sensors (410) of FIG. 4) in operation 1010. The processor (350) can compare the obtained multiple pressure values ​​in operation 1015. In operation 1020, the processor (350) can check whether the difference between the multiple pressure values ​​falls within a specified range. If the difference between the multiple pressure values ​​falls within a specified range (e.g., YES in operation 1020), the processor (350) can determine in operation 1025 that pressure has occurred according to the finger size of the user wearing the wearable electronic device (200).

[0172] In one embodiment, pressure according to the size of the finger of a user wearing the wearable electronic device (200) may include pressure according to finger swelling (or edema).

[0173] In one embodiment, if the difference between a plurality of pressure values ​​is not included within a specified range (e.g., NO of operation 1020), the processor (350) may determine that pressure caused by user activity occurred in operation 1030.

[0174] In one embodiment, pressure caused by user activity may include pressure caused by user movement. However, it is not limited thereto. Pressure caused by user activity may also include user input for executing a specific function.

[0175] In one embodiment, pressure caused by user activity may include pressure (e.g., force) applied from outside the wearable electronic device (200) in the direction of the opening of the wearable electronic device (200) (e.g., opening (2001) in FIG. 2 and FIG. 4) (e.g., 461, 463 in FIG. 4). In this case, the pressure values ​​measured through each of the plurality of pressure sensors (410) (e.g., first pressure sensor (410a), second pressure sensor (410b), third pressure sensor (410c), fourth pressure sensor (410d), and fifth pressure sensor (410e)) may have different values. For example, at least one or two pressure values ​​among the pressure values ​​measured through a plurality of pressure sensors (410) (e.g., a first pressure sensor (410a), a second pressure sensor (410b), a third pressure sensor (410c), a fourth pressure sensor (410d), and a fifth pressure sensor (410e)) may differ from at least two or three other pressure values. For example, among the plurality of pressure sensors (410), the pressure value measured by at least one pressure sensor that detects pressure (e.g., force) applied in the direction of the opening of the wearable electronic device (200) (e.g., opening (2001) in FIG. 2 and FIG. 4) (e.g., 461, 463 in FIG. 4) from outside the wearable electronic device (200) may differ from the pressure values ​​measured by at least two pressure sensors that do not detect pressure (e.g., force) applied in the direction of the opening of the wearable electronic device (200) (e.g., opening (2001) in FIG. 2 and FIG. 4) (e.g., 461, 463 in FIG. 4) from outside the wearable electronic device (200). Accordingly, the difference between the plurality of pressure values ​​may not be included within a specified range, and based on this, the processor (350) may determine that pressure has been generated by the user's activity.

[0176] In one embodiment, based on a plurality of pressure values, it was determined that pressure according to the user's finger size or pressure due to the user's activity was generated, but is not limited thereto.

[0177] For example, the processor (350) may determine whether pressure according to the size of the user's finger or pressure caused by the user's activity has occurred by using multiple pressure values ​​as well as blood flow information obtained through at least one biometric sensor (e.g., PPG sensor (231-1, 231-2, 231-3, 232-1, 232-2) of FIG. 2), temperature information obtained through a temperature sensor (e.g., temperature sensor (211) of FIG. 2), and / or electrical characteristics of the skin.

[0178] In one embodiment, when a user wears at least one second wearable electronic device (not shown) (e.g., a wearable electronic device worn on another finger, a wearable electronic device wearable on the wrist and / or ankle), the processor (350) may receive a plurality of pressure values, blood flow information, temperature information, and / or electrical characteristics of the skin from at least one second wearable electronic device. In this case, the processor (350) may determine whether pressure according to the user's finger size or pressure caused by the user's activity has occurred by considering the plurality of pressure values, blood flow information, temperature information, and / or electrical characteristics of the wearable electronic device (200), as well as the plurality of pressure values, blood flow information, temperature information, and / or electrical characteristics of the skin received from at least one second wearable electronic device.

[0179] FIG. 11 is a flowchart illustrating a method for outputting a notification related to the attachment and detachment of a wearable electronic device (200) according to one embodiment of the present disclosure.

[0180] In the following embodiments, each operation of FIG. 11 may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation of FIG. 11 may be changed, and at least two operations may be performed in parallel.

[0181] According to one embodiment, operations 1105 to 1130 of FIG. 11 may be understood to be performed in a processor (e.g., processor (350) of FIG. 3) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4).

[0182] FIG. 11 according to one embodiment may be an additional operation of operation 1025 of FIG. 9 or FIG. 10 described above.

[0183] In one embodiment, the processor (350) may obtain a reference pressure value based on a plurality of pressure values ​​obtained through a plurality of pressure sensors (e.g., pressure sensor (331) of FIG. 3, a plurality of pressure sensors (410) of FIG. 4) in operation 1105. For example, the reference pressure value may include a minimum pressure value, a maximum pressure value, a mode pressure value, an intermediate pressure value, a final pressure value, or an average pressure value among the plurality of pressure values. However, it is not limited thereto.

[0184] In one embodiment, the processor (350) can estimate the level of swelling of the user's finger based on a reference pressure value in operation 1110. In operation 1115, the processor (350) can store the estimated level of swelling of the user's finger in memory (e.g., memory (320) of FIG. 3). For example, the processor (350) can score the level of swelling of the user's finger based on the reference pressure value and store it in memory (320).

[0185] In one embodiment, the processor (350) can determine in operation 1120 whether the swelling level exceeds a first specified swelling level or whether the swelling change amount exceeds a specified swelling change amount.

[0186] In one embodiment, if the swelling level exceeds a first specified swelling level or the amount of swelling change exceeds a specified amount of swelling change (e.g., YES of operation 1120), the processor (350) can determine in operation 1125 whether the swelling level is predicted to exceed a second specified swelling level within a specific time.

[0187] In one embodiment, if it is predicted that the swelling level will exceed the second specified swelling level within a specific time (e.g., YES of operation 1125), the processor (350) may output a notification related to the removal of the wearable electronic device (200) in operation 1130. For example, if it is predicted that the swelling level will exceed the second specified swelling level within a specific time (e.g., about 1 hour), the processor (350) may determine that it is difficult to remove the wearable electronic device (200) within a specific time (e.g., about 1 hour) and output a notification related to the removal of the wearable electronic device (200).

[0188] For example, the processor (350) may emit light through a light-emitting PPG sensor (e.g., the light-emitting PPG sensors (231-1, 231-2, 231-3) of FIG. 2) to output a notification that induces the removal of the wearable electronic device (200). It is not limited thereto. For example, if the wearable electronic device (200) includes a speaker (e.g., the acoustic output module (155) of FIG. 1), the processor (350) may output a notification that induces the removal of the wearable electronic device (200) through the speaker. In one embodiment, the processor (350) may output a notification that induces the removal of the wearable electronic device (200) through a haptic module (179). In one embodiment, when communication is established with at least one external electronic device (e.g., a smartphone, a smart watch, and / or a wireless audio device), a signal related thereto may be transmitted to at least one external electronic device to output a notification inducing the removal of the wearable electronic device (200) through the communication-established at least one external electronic device.

[0189] In one embodiment, although not illustrated, if the detachment of the wearable electronic device (200) is not detected even though there is a situation where the wearable electronic device (200) is difficult to detach (e.g., a situation where high pressure is expected that makes it difficult for a finger to come off the wearable electronic device (200)), the processor (350) can acquire multiple pressure values ​​through multiple pressure sensors (410) at specified time intervals. Based on the acquired multiple pressure values, if the processor (350) determines that the wearable electronic device (200) is in a situation where it can be detached, it can output a notification related to the detachment of the wearable electronic device (200).

[0190] In one embodiment, if the swelling level does not exceed a first specified swelling level or the swelling change amount does not exceed a specified swelling change amount (e.g., NO of operation 1120), the processor (350) may branch to operation 905 (or operation 1010) to obtain multiple pressure values ​​through multiple pressure sensors (410).

[0191] In one embodiment, if the swelling level does not exceed a second specified swelling level within a specific time (e.g., NO of operation 1125), the processor (350) may branch to operation 905 (or operation 1010) to obtain multiple pressure values ​​through multiple pressure sensors (410).

[0192] In one embodiment, although not illustrated, the processor (350) may analyze changes in finger swelling and provide guidance information to the user. For example, the processor (350) may record changes in finger swelling on a daily, weekly, monthly, and / or yearly basis and may analyze changes in finger swelling on a daily, weekly, monthly, and / or yearly basis. Based on the analyzed changes in finger swelling, the processor (350) may provide guidance information suitable for the user. For example, the guidance information may include the time when finger swelling mainly occurs and / or the cause of finger swelling. However, it is not limited thereto. For example, the processor (350) may provide the user with information on when finger swelling occurs during the day, for example, morning, lunchtime, or late night. In one embodiment, the processor (350) may predict (or estimate) the cause of finger swelling based on female cycles, stress records, and / or exercise records, and provide the user with the cause of finger swelling.

[0193] In one embodiment, although not illustrated, if dietary information is stored in memory (320), the processor (350) may refer to the dietary information and provide the user with food presumed to have caused swelling of the finger. Accordingly, the user may be able to correct their dietary habits.

[0194] FIG. 12 is a flowchart illustrating a method for providing an exercise guide according to one embodiment of the present disclosure.

[0195] In the following embodiments, each operation of FIG. 12 may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation of FIG. 12 may be changed, and at least two operations may be performed in parallel.

[0196] According to one embodiment, operations 1205 to 1215 of FIG. 12 may be understood to be performed in a processor (e.g., processor (350) of FIG. 3) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4).

[0197] FIG. 12 according to one embodiment may be an additional operation of the operation 1030 of FIG. 10 described above.

[0198] In one embodiment, the processor (350) can obtain movement information of the wearable electronic device (200) through a motion sensor (e.g., the motion sensor (335) of FIG. 3) in operation 1205. In one embodiment, the motion sensor (335) may include at least one of a 3-axis sensor, a 6-axis sensor, an accelerometer, or a gyroscope. The processor (350) can obtain movement information of the wearable electronic device (200) through the motion sensor (335). For example, the movement information of the wearable electronic device (200) obtained through the motion sensor (335) may include acceleration information of the wearable electronic device (200), posture information (e.g., angle information, direction information), and / or coordinate information according to the movement of the wearable electronic device (200) (e.g., gesture information, movement information). However, it is not limited thereto.

[0199] In one embodiment, the processor (350) can determine the type of movement based on the movement information of the wearable electronic device (200) and a plurality of pressure sensor information in the operation.

[0200] For example, the processor (350) can measure changes in movement of the wearable electronic device (200) based on movement information of the wearable electronic device (200). The processor (350) can measure changes in multiple pressure values ​​based on multiple pressure sensor information obtained through multiple pressure sensors (e.g., pressure sensor (331) of FIG. 3, multiple pressure sensors (410) of FIG. 4). For example, the processor (350) can obtain multiple pressure values ​​through multiple pressure sensors (e.g., pressure sensor (331) of FIG. 3, multiple pressure sensors (410) of FIG. 4) at specified time intervals (e.g., time interval set on the wearable electronic device (200) or time interval set by the user) (or periods). The processor (350) can store the multiple pressure sensor values ​​obtained at specified time intervals as multiple pressure sensor information in memory (e.g., memory (320) of FIG. 3). The processor (350) can measure changes in multiple pressure values ​​based on multiple pressure sensor information.

[0201] In one embodiment, the memory (320) may store a learning model for each exercise type that has learned changes in pressure values ​​and / or changes in movement according to the movement of each exercise type. Exercise types may include bare-hand exercises (e.g., push-ups, mountain climbers, sit-ups), equipment exercises (e.g., rowing machine, pull-ups, bench press), and / or ball sports (e.g., golf, baseball, tennis). However, they are not limited thereto.

[0202] In one embodiment, the processor (350) can determine a type of motion corresponding to a change in movement of the measured wearable electronic device (200) and a change in a plurality of pressure values ​​based on a learning model for each type of motion stored in memory (320).

[0203] In one embodiment, the processor (350) may provide information related to the determined exercise type in the 1215 operation. When the exercise type is determined, the processor (350) may obtain movement information and / or pressure values ​​related to the exercise performance using a motion sensor (335) and / or a plurality of pressure sensors (410). Based on the obtained movement information and / or pressure values ​​related to the exercise performance, the processor (350) may analyze whether the exercise is strenuous on the fingers or hands and provide information related to the exercise type, for example, the risk of finger injury, to the user. Not limited thereto, the processor (350) may provide count information (e.g., push-up count information, sit-up count information) and / or posture guide information to the user based on the obtained movement information and / or pressure values ​​related to the exercise performance.

[0204] As seen in FIGS. 9, 10, 11, and 12 according to various embodiments, the wearable electronic device (200) can distinguish pressure according to finger size or pressure according to user activity based on multiple pressure values ​​obtained through multiple pressure sensors. If the wearable electronic device (200) confirms that pressure according to finger size (e.g., pressure due to finger edema (or swelling)) is detected based on multiple pressure values, it can provide a notification related to the removal of the wearable electronic device so that the user does not feel pain in the finger wearing the wearable electronic device. If the wearable electronic device (200) confirms that pressure according to user activity is detected based on multiple pressure values, or if an activity, e.g., an exercise state, is detected, it can provide a notification related to the exercise state so that the user can assist in performing exercise.

[0205] FIG. 13 is a drawing for explaining a method of providing a notification based on daily recorded user finger swelling information according to one embodiment of the present disclosure.

[0206] FIG. 14 is a drawing for explaining a method of providing a notification based on time-recorded user finger swelling information according to one embodiment of the present disclosure.

[0207] According to one embodiment, FIG. 13 is a graph showing swelling information of a user's finger recorded by date, and FIG. 14 is a graph showing swelling information of a user's finger recorded by time.

[0208] Referring to FIG. 13, the x-axis represents daily (1310) and the y-axis represents the average value (kPa) (1320) of the pressure sensor. Referring to FIG. 14, the x-axis represents time (1410) and the y-axis represents the average value (kPa) (1420) of the pressure sensor.

[0209] Referring to FIGS. 13 and 14, in one embodiment, a plurality of reference pressure values ​​may be set to determine the swelling level of a user. For example, the plurality of reference pressure values ​​may include a minimum pressure average reference pressure value (1330) (e.g., about 0.2 kPa), an absolute swelling detection pressure value (1335) (e.g., about 2.0 kPa), a relative swelling detection pressure value (1340) (e.g., about 2.2 kPa), and a pain detection pressure value (1345) (e.g., about 20 kPa) on a daily basis.

[0210] In FIG. 13 and FIG. 14 according to one embodiment, when the level of swelling of the finger is greater than or equal to the relative swelling detection pressure value (1340), it is assumed that finger swelling has been detected and will be explained.

[0211] In FIG. 13 and FIG. 14 according to one embodiment, there were evening gatherings (e.g., company dinners, parties, drinking appointments) on the 1st, 7th, 12th, 19th, and 26th days, and the 4th to 8th days may be the female cycle.

[0212] In one embodiment, the processor (e.g., the processor (350) of FIG. 3) can determine, based on the daily median (1445) and considering the evening gathering, that swelling of the finger due to salt intake at night occurred on the 1st day (1351), 7th day (1353), 12th day (1355), 19th day (1357), and 26th day (1359), and that swelling of the finger due to the female cycle occurred on the 4th to 8th days.

[0213] In one embodiment, when the user inputs the food consumed, the processor (350) may provide the user with the food that caused the swelling of the finger. This is not limited thereto, and the processor (350) may estimate the cause of the swelling of the finger by checking dinner appointment information in the calendar or messages, or by checking late-night snack information through payment history and application usage information. Based on the cause of the swelling of the finger estimated through the late-night snack information, the processor (350) may provide the user with the food that caused the swelling of the finger.

[0214] In FIG. 13 according to one embodiment, it can be seen that on January 6, a pressure value (1353, 1460) exceeding a pain detection pressure value (1345) (e.g., about 20 kPa) is detected. In this case, the processor (350) may use an absolute swelling detection pressure value (1335) (e.g., about 2.0 kPa) to induce removal so that the user can remove the wearable electronic device (200) in advance by confirming the possibility of finger pain due to swelling of the finger. For example, if an absolute swelling detection pressure value (1335) (e.g., about 2.0 kPa) is used, a notification regarding the removal of the wearable electronic device (200) may be output when the swelling level of the finger reaches about 18 kPa (1455), which is about 90% of the pain detection pressure value (1345) (e.g., about 20 kPa) (1465) (e.g., 4:00 AM on January 6). This is not limited to this, but the processor (350) may also output a notification regarding the removal of the wearable electronic device (200) before a specific time (e.g., 1 hour) based on a trend. For example, by using a logarithmic trend, it is predicted that the pain detection pressure value (1345) (e.g., about 20 kPa) will be reached at 6 a.m., and a notification regarding the removal of the wearable electronic device (200) may be output at 5 a.m., which is a specific time (e.g., 1 hour) before.

[0215] In one embodiment, the processor (350) can predict the timing of finger swelling through learning (e.g., substantially the same as the female cycle) when it is determined from data over several months that finger pain may occur according to a monthly cycle, and provide the user with the possibility of finger pain in advance before going to sleep. For example, the processor (350) can predict that finger pain may occur during the female cycle from January 4 to 8 and provide the user with a notification recommending that the wearable electronic device (200) be removed and the user go to sleep on the evening of January 3.

[0216] In one embodiment, when using a relative swelling detection pressure value (1340) (e.g., about 2.2 kPa), the reference pressure value can be personalized. For example, pressure changes due to swelling of the finger may have a large daily / monthly range of variation and a large trend of increase or decrease, whereas in the case of a situation where the finger width has increased (e.g., a situation where the finger width increases due to weight gain or loss, or a situation where the finger width increases due to growth), the trend direction may be constant or the level of change may be small. Taking this into account, the daily median and maximum values ​​due to swelling of the finger may be changed. In one embodiment, although the minimum pressure value may change over a certain period, if the pressure value does not drop and remains constant for a certain period, the processor (350) may determine that the finger width has increased rather than the finger swelling and provide a notification suggesting a size exchange of the wearable electronic device (200) (e.g., a notification suggesting wearing a wearable electronic device (200) that is one size larger (or one size smaller).

[0217] FIG. 15 is a cross-sectional view of a wearable electronic device (200) viewed from the front, according to one embodiment of the present disclosure.

[0218] Referring to FIG. 15, the wearable electronic device (200) may include at least some similarities to the electronic device (101) of FIG. 1 and / or the wearable electronic device (200) of FIG. 2 and FIG. 4, or may further include other embodiments of the electronic device and / or the wearable electronic device.

[0219] The wearable electronic device (200) illustrated in FIG. 15 according to one embodiment may include a ring-type (e.g., ring shape, ring form) wearable electronic device. The housing (401) of the wearable electronic device (200) (e.g., the housing (201) of FIG. 2) may be formed of a metal material. For example, at least a portion (1510) of the housing (401) of the wearable electronic device (200) illustrated in FIG. 15 according to one embodiment may be formed of a flexible material.

[0220] In one embodiment, the wearable electronic device (200) may include at least one distance detection sensor (e.g., the distance detection sensor (333) of FIG. 3). For example, the at least one distance detection sensor may include a distance measuring sensor (1530), and / or a strain sensor (1520) (or a resistance sensor, a capacitance sensor). However, it is not limited thereto.

[0221] In one embodiment, the distance measuring sensor (1530) may be placed in the internal space (1511) of at least a portion (1510) of the housing (401) formed of a flexible material. For example, the distance measuring sensor (1530) may be placed on one side of at least a portion of the housing (401) formed of a flexible material. The other side of at least a portion of the housing (401) may be formed as a flexible portion (1540).

[0222] In one embodiment, the distance measuring sensor (1530) can measure the distance between at least one side of a portion of the housing (401) and at least one other side (or flexible portion (1540)) of a portion of the housing (401).

[0223] In one embodiment, the distance measuring sensor (1530) may include a light-emitting part and a light-receiving part. In one embodiment, the light-emitting part may generate a light signal (e.g., LED, laser, VCSEL) or an acoustic signal (e.g., sound, ultrasound, surface acoustic wave (SAW), body acoustic wave (BAW). The light-receiving part may include an image sensor comprising a plurality of photodiodes or a plurality of pixels.

[0224] In one embodiment, a light-emitting part may be disposed on one side of at least a portion of a housing (401) formed of a flexible material, and a light-receiving part may be disposed on the other side of at least a portion of the housing (401). In this case, the processor (350) may cause a light signal to be emitted through the light-emitting part. The light-receiving part may receive at least a portion of the light signal emitted from the light-emitting part. Based on at least a portion of the light signal received through the light-receiving part, the processor (350) may measure the distance between one side of at least a portion of the housing (401) and the other side of at least a portion of the housing (401) (or the flexible part (1540)).

[0225] This is not limited thereto, and a light-emitting part and a light-receiving part may be disposed on at least one side of a portion of a housing (401) formed of a flexible material, and a reflective part may be disposed on at least one side of a portion of the housing (401). In this case, the processor (350) may cause a light signal to be emitted through the light-emitting part. At least a portion of the light signal emitted from the light-emitting part may be reflected by the reflective part and received by the light-receiving part. Based on at least a portion of the light signal received through the light-receiving part, the processor (350) may measure the distance between at least one side of a portion of the housing (401) and at least one side of a portion of the housing (401) (or the flexible part (1540)).

[0226] In one embodiment, when a light signal is emitted through a light-emitting unit, a light-receiving unit can detect (or confirm) that the center of the received light is moving away from the center of the wearable electronic device (200). In one embodiment, in the case of a sound wave signal, a change in pressure value can be estimated through a shift of the peak wavelength, a change in intensity, a change in phase, a calculation of the time of arrival, or a combination thereof.

[0227] In one embodiment, the light-emitting part may generate a light signal, and the generated light signal may be reflected by the reflecting part, and by the light-receiving part detecting the reflected light, the distance between at least one side of the housing (401) and at least one other side of the housing (401) (or the flexible part (1540)) can be measured.

[0228] In one embodiment, when the distance between at least one side of the housing (401) of the wearable electronic device (200) and at least the other side (or flexible part (1540)) of the housing (401) of the wearable electronic device (200) exceeds a specified distance due to pressure (e.g., force) applied from the inside of the wearable electronic device (200) (e.g., opening (2001) of FIG. 3) to the outside direction (1550) of the wearable electronic device (200), the processor (350) may determine that pressure has been generated according to the finger size of the user wearing the wearable electronic device (200).

[0229] In one embodiment, when the distance between at least one side of the housing (401) of the wearable electronic device (200) and at least the other side (or soft part (1540)) of the housing (401) does not exceed a specified distance due to pressure (e.g., force) applied from the outside of the wearable electronic device (200) toward the inside (e.g., opening (2001)) of the wearable electronic device (200), the processor (350) may determine that pressure has been generated by the user's activity.

[0230] In one embodiment, the strain sensor (1520) may be placed in the internal space (1511) of at least a portion (1510) of the housing (401) formed of a flexible material.

Not limited thereto, a resistance sensor or a capacitance sensor may be placed in the internal space (1511) of at least a portion (1510) of the housing (401) instead of the strain sensor (1520).

[0231] In one embodiment, a strain sensor (1520), a resistance sensor, or a capacitance sensor may detect a change in curvature of the wearable electronic device (200) (e.g., a change in curvature of at least a portion of the housing (401) formed of a flexible material). Based on the change in curvature of the wearable electronic device (200) (e.g., a change in curvature of at least a portion of the housing (401) formed of a flexible material) detected through the strain sensor (1520), the resistance sensor, or the capacitance sensor, the processor (350) may determine whether pressure has occurred due to the size of the finger of the user wearing the wearable electronic device (200) or due to the user's activity. For example, the processor (350) can determine whether pressure is generated according to the size of the finger of the user wearing the wearable electronic device (200) or pressure is generated due to the user's activity, based on the direction in which the wearable electronic device (200) changes due to the change in curvature of the wearable electronic device (200) detected through the strain sensor (1520).

[0232] In one embodiment, when a change in curvature of the wearable electronic device (200) exceeds a specified change value due to pressure (e.g., force) applied from the inside (e.g., opening (2001)) of the wearable electronic device (200) to the outside direction (1550) of the wearable electronic device (200), the processor (350) may determine that pressure has occurred according to the finger size of the user wearing the wearable electronic device (200).

[0233] In one embodiment, if the change in curvature of the wearable electronic device (200) does not exceed a specified change value due to pressure (e.g., force) applied from the outside of the wearable electronic device (200) toward the inside of the wearable electronic device (200) (e.g., opening (2001)) (1560), the processor (350) may determine that pressure has been generated by the user's activity.

[0234] In one embodiment, the processor (350) can detect a change in resistance due to bending of the resistance circuit pattern through a resistance sensor to determine whether pressure has occurred due to the size of the finger of the user wearing the wearable electronic device (200) or due to the user's activity. In one embodiment, the processor (350) can detect a change in capacitance through a capacitance sensor to determine whether pressure has occurred due to the size of the finger of the user wearing the wearable electronic device (200) or due to the user's activity.

[0236] In one embodiment, if the change in resistance (or change in capacitance detected through a capacitance sensor) due to bending of the resistance circuit pattern by pressure (e.g., force) applied from the outside of the wearable electronic device (200) toward the inside of the wearable electronic device (200) (e.g., opening (2001)) (1560) does not exceed a specified change value, the processor (350) may determine that pressure caused by user activity has occurred.

[0250] According to one embodiment of FIG. 18 <1810> Referring to the above, the housing (401) of the wearable electronic device (200) (e.g., the housing (201) of FIG. 2) is formed of a metal material, and at least a portion (1510) of the housing (401) of the wearable electronic device (200) may be formed of a soft material.

[0251] In one embodiment, the wearable electronic device (200) may include at least one distance detection sensor (e.g., the distance detection sensor (333) of FIG. 3). For example, the at least one distance detection sensor may include a distance measuring sensor (1530) and / or a strain sensor (1520) (or a resistance sensor, a capacitance sensor).

Not limited thereto, a strain sensor (1520) may detect a change in curvature of the wearable electronic device (200). Based on whether the detected change in curvature of the wearable electronic device (200) exceeds a specified change value, the processor (350) may determine that pressure has occurred due to the finger size of the user wearing the wearable electronic device (200) or due to the user's activity.

[0255] FIG. 19 is a drawing for explaining at least one distance detection sensor (333) according to one embodiment of the present disclosure.

[0256] FIG. 19, according to various embodiments, is a schematic diagram showing an unfolded configuration of a housing (401) (e.g., housing (201) of FIG. 2) and a substrate (240).

[0257] Referring to FIG. 19, a wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2 to 4) may include a substrate (240) disposed in the internal space of a housing (401). At least a portion of the housing (401) may be formed into a molding portion (405) that encloses the component included (or disposed) in the substrate (240) to secure it. In one embodiment, at least another portion of the housing (401) may be formed from a flexible material (1913).

[0258] In one embodiment, the wearable electronic device (200) may include at least one distance detection sensor (e.g., the distance detection sensor (333) of FIG. 3).

[0259] For example, of Fig. 19 <1910> As illustrated in the figure, at least one distance detection sensor (333) may include a strain sensor (1520). The strain sensor (1520) may be connected to at least a portion of the substrate (240) and placed on at least another portion of the housing (401) formed of a flexible material (1913).

[0260] In one embodiment, of FIG. 19 <1950> As illustrated in Fig. 15, at least one distance detection sensor (333) may include a distance measuring sensor (e.g., the distance measuring sensor (1530) of Fig. 15). The distance measuring sensor (1530) may include a light-emitting part (1955) and a light-receiving part (1960). The light-emitting part (1955) and the light-receiving part (1960) may face each other when the wearable electronic device (200) is implemented in a ring shape.

[0261] FIG. 20 is a drawing for explaining a method for detecting finger size according to one embodiment of the present disclosure.

[0262] In FIG. 20 according to various embodiments, the size of the wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2 to 4) has a radius of “10” (2001) (e.g., R10), and at least a portion of the housing of the wearable electronic device (200) formed of a flexible material (e.g., the housing (201) of FIG. 2, the housing (401) of FIG. 4) is described as being configured to be about 5 degrees.

[0263] Referring to FIG. 20, when the inner diameter of the wearable electronic device (200) measured by at least one distance detection sensor (e.g., distance detection sensor (333) of FIG. 3) increases by about 0.1 mm (2030), the size of the wearable electronic device (200) may have a radius of “10.1” (2030).

[0264] In one embodiment, a light-emitting part may be disposed on at least one side (2010) of a housing (401) formed of a flexible material, and a light-receiving part may be disposed on at least one other side (2005) of the housing (401).

[0265] According to one embodiment, the first distance (2040) at which a light signal emitted through a light-emitting part is received by a light-receiving part as the inner diameter of the wearable electronic device (200) changes may be greater than the second distance (2020) at which a light signal emitted through a light-emitting part is received by a light-receiving part when the inner diameter of the wearable electronic device (200) does not change. Based on the change in the distance at which the light signal reaches the wearable electronic device (200), the wearable electronic device (200) may determine that pressure is generated according to the finger size of the user wearing the wearable electronic device (200).

[0266] According to one embodiment, the first distance (2040) at which a light signal emitted through a light-emitting part is received by a light-receiving part as the inner diameter of the wearable electronic device (200) changes may be smaller than the second distance (2020) at which a light signal emitted through a light-emitting part is received by a light-receiving part when the inner diameter of the wearable electronic device (200) does not change. In this case, the processor (350) may determine that pressure is generated by the user's activity in the wearable electronic device (200).

[0267] FIG. 21 is a drawing for explaining a distance detection sensor (333) according to one embodiment of the present disclosure.

[0268] Figure 21 <2110> Referring to the above, a substrate (240) may be disposed in the internal space of a housing (401) (e.g., housing (201) of FIG. 2) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4). The area in the internal space of the housing (401) where the substrate (240) is disposed may include a molding portion (405) (e.g., resin) formed to surround at least one component disposed on the substrate (240) in order to secure the component.

[0269] In one embodiment, the wearable electronic device (200) may include a plurality of light receiving units. For example, a first light receiving unit (2115) may be disposed on a first surface of the substrate (240) (e.g., a surface facing direction ① (e.g., a surface facing the opening (2001) of FIG. 2), and a second light receiving unit (2120) may be disposed on a second surface of the substrate (240) (e.g., a surface facing direction ② (e.g., a surface facing in the opposite direction to the opening (2001) of FIG. 2). This is not limited thereto, and FIG. 21 <2130> Referring to the first surface of the substrate (240) (e.g., the surface facing direction ①), a plurality of light receiving parts (2135) (e.g., a light receiving part array) may be arranged.

[0270] Figure 21 <2150> Referring to the above, if the wearable electronic device (200) includes a plurality of light receiving units (2135) (e.g., a light receiving unit array), a light signal (2155) emitted through a light emitting unit (e.g., a light emitting unit (1955) of FIG. 19) can be reflected by a reflection unit (2160) and received by a plurality of light receiving units (2135) (e.g., a light receiving unit array).

[0271] In one embodiment, the processor (350) can determine whether pressure has been generated according to the size of the finger of a user wearing the wearable electronic device (200) or pressure has been generated due to the user's activity, based on a light signal received through a plurality of light receiving units (2135) (e.g., a light receiving unit array).

[0272] FIG. 22 is a flowchart illustrating a finger size detection method according to one embodiment of the present disclosure.

[0273] In the following embodiments, each operation of FIG. 22 may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation of FIG. 22 may be changed, and at least two operations may be performed in parallel.

[0274] According to one embodiment, operations 2205 to 2220 of FIG. 22 can be understood as being performed in a processor (e.g., processor (350) of FIG. 3) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4).

[0275] In one embodiment, the processor (350) can measure the distance between the two ends of the housing of the wearable electronic device (200) (e.g., the housing (201) of FIG. 2, the housing (401) of FIG. 4) in operation 2205 through a distance detection sensor (e.g., the distance detection sensor (333) of FIG. 3). For example, the distance detection sensor (333) may be placed in the internal space of the housing (201, 401) near an opening formed in a part area of ​​the housing (201, 401) (e.g., the opening (1611) of FIG. 16). The processor (350) can measure the length between one end of the opening (1611) and the other end of the opening (1611) through the distance detection sensor (333).

[0276] In one embodiment, the processor (350) may determine in operation 2210 whether the distance between the two ends of the housing (201, 401) of the measured wearable electronic device (200) exceeds a specified distance. If it is determined that the distance between the two ends of the housing (201, 401) of the measured wearable electronic device (200) exceeds a specified distance (e.g., YES in operation 2210), the processor (350) may determine in operation 2215 that pressure has occurred according to the finger size of the user wearing the wearable electronic device (200). For example, if the distance between the two ends of the housing (201, 401) of the wearable electronic device (200) exceeds a specified distance due to pressure (e.g., force) applied from the inside of the wearable electronic device (200) (e.g., opening (2001) in FIG. 3) to the outside of the wearable electronic device (200) (e.g., 1550 in FIG. 15, 1620 in FIG. 16), the processor (350) may determine that pressure has been generated according to the finger size of the user wearing the wearable electronic device (200).

[0277] In one embodiment, pressure according to the size of the finger of a user wearing the wearable electronic device (200) may include pressure according to finger swelling (or edema).

[0278] In one embodiment, if it is determined that the distance between the two ends of the housing (201, 401) of the measured wearable electronic device (200) does not exceed a specified distance (e.g., NO of operation 2210), the processor (350) may determine in operation 2220 that pressure caused by user activity has occurred. For example, if the distance between the two ends of the housing (201, 401) does not exceed a specified distance due to pressure (e.g., force) applied from the outside of the wearable electronic device (200) toward the inside of the wearable electronic device (200) (e.g., opening (2001)) (e.g., 1560 in FIG. 15, 1630 in FIG. 16), the processor (350) may determine that pressure caused by user activity has occurred.

[0279] In one embodiment, the pressure caused by the user's activity may include the pressure caused by the user's movement. However, it is not limited thereto.

[0280] In FIG. 22 according to various embodiments, it is described that an opening (1611) is formed in a part of the housing (201, 401), but this is not limited thereto. For example, the opening (1611) formed in a part of the housing (201, 401) may include a flexible material (e.g., a flexible part). In this case, a distance detection sensor (333) may be disposed on one side of the housing (201, 401) within the internal space of the flexible material (e.g., a flexible part) formed in a part of the housing (201, 401).

[0281] FIG. 23 is a flowchart illustrating a method for outputting a notification related to the attachment and detachment of a wearable electronic device (200) according to one embodiment of the present disclosure.

[0282] In the following embodiments, each operation of FIG. 23 may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation of FIG. 23 may be changed, and at least two operations may be performed in parallel.

[0283] According to one embodiment, operations 2305 to 2330 of FIG. 23 can be understood as being performed in a processor (e.g., processor (350) of FIG. 3) of a wearable electronic device (e.g., electronic device (101) of FIG. 1, wearable electronic device (200) of FIG. 2 to 4).

[0284] FIG. 23 according to one embodiment may be an additional operation of operation 2215 of FIG. 22 described above.

[0285] In one embodiment, the processor (350) may obtain a reference distance in operation 2305 based on the distance between the two ends of the housing of the wearable electronic device (200) (e.g., the housing (201) in FIG. 2, the housing (401) in FIG. 4) measured by a distance detection sensor (e.g., the distance detection sensor (333) in FIG. 3). For example, the reference distance may include a minimum distance, a maximum distance, a mode distance, an intermediate distance, a final distance, or an average distance among the distances between the two ends of the plurality of measured housings (401). However, it is not limited thereto.

[0286] In one embodiment, the processor (350) can estimate the level of swelling of the user's finger based on a reference distance in operation 2310. In operation 2315, the processor (350) can store the estimated level of swelling of the user's finger in memory (e.g., memory (320) of FIG. 3). For example, the processor (350) can score the level of swelling of the user's finger based on the reference distance and store it in memory (320).

[0287] In one embodiment, the processor (350) can determine in the 2320 operation whether the swelling level exceeds a first specified swelling level or whether the swelling change amount exceeds a specified swelling change amount.

[0288] In one embodiment, if the swelling level exceeds a first specified swelling level or the amount of swelling change exceeds a specified amount of swelling change (e.g., YES of operation 2320), the processor (350) can determine in operation 2325 whether the swelling level is predicted to exceed a second specified swelling level within a specific time.

[0289] In one embodiment, if it is predicted that the swelling level will exceed the second specified swelling level within a specific time (e.g., YES of operation 2325), the processor (350) may output a notification related to the removal of the wearable electronic device (200) in operation 2330. For example, if it is predicted that the swelling level will exceed the second specified swelling level within a specific time (e.g., about 1 hour), the processor (350) may determine that it is difficult to remove the wearable electronic device (200) within a specific time (e.g., about 1 hour) and output a notification related to the removal of the wearable electronic device (200).

[0290] For example, the processor (350) may emit light through a light-emitting PPG sensor (e.g., the light-emitting PPG sensors (231-1, 231-2, 231-3) of FIG. 2) to output a notification that induces the removal of the wearable electronic device (200). It is not limited thereto. For example, if the wearable electronic device (200) includes a speaker (e.g., the acoustic output module (155) of FIG. 1), the processor (350) may output a notification that induces the removal of the wearable electronic device (200) through the speaker. In one embodiment, the processor (350) may output a notification that induces the removal of the wearable electronic device (200) through a haptic module (179). In one embodiment, when communication is established with at least one external electronic device (e.g., a smartphone, a smart watch, and / or a wireless audio device), a signal related thereto may be transmitted to at least one external electronic device to output a notification inducing the removal of the wearable electronic device (200) through the communication-established at least one external electronic device.

[0291] In one embodiment, although not illustrated, if the detachment of the wearable electronic device (200) is not detected even when there is a situation where the wearable electronic device (200) is difficult to detach (e.g., a situation where high pressure is expected that makes it difficult for a finger to come off the wearable electronic device (200)), the processor (350) can measure the distance between the two ends of the housing (401) of the wearable electronic device (200) through the distance detection sensor (333) at specified time intervals. Based on the measured distance between the two ends of the housing (401) of the wearable electronic device (200), if the processor (350) determines that the wearable electronic device (200) is in a situation where it can be detached, it can output a notification related to the detachment of the wearable electronic device (200).

[0292] In one embodiment, if the swelling level does not exceed a first specified swelling level or the amount of swelling change does not exceed a specified amount of swelling change (e.g., NO of operation 2320), the processor (350) branches to operation 2205 to measure the distance between the two ends of the housing (401) of the wearable electronic device (200) through the distance detection sensor (333).

[0293] In one embodiment, if the swelling level does not exceed a second specified swelling level within a specific time (e.g., NO of operation 2325), the processor (350) branches to operation 2205 to measure the distance between the two ends of the housing (401) of the wearable electronic device (200) through the distance detection sensor (333).

[0294] In one embodiment, although not illustrated, the processor (350) may analyze changes in finger swelling and provide guidance information to the user. For example, the processor (350) may record changes in finger swelling on a daily, weekly, monthly, and / or yearly basis and may analyze changes in finger swelling on a daily, weekly, monthly, and / or yearly basis. Based on the analyzed changes in finger swelling, the processor (350) may provide guidance information suitable for the user. For example, the guidance information may include the time when finger swelling mainly occurs and / or the cause of finger swelling. However, it is not limited thereto. For example, the processor (350) may provide the user with information on when finger swelling occurs during the day, for example, morning, lunchtime, or late night. In one embodiment, the processor (350) may predict (or estimate) the cause of finger swelling based on female cycles, stress records, and / or exercise records, and provide the user with the cause of finger swelling.

[0295] In one embodiment, although not illustrated, if dietary information is stored in memory (320), the processor (350) may refer to the dietary information and provide the user with food presumed to have caused swelling of the finger. Accordingly, the user may be able to correct their dietary habits.

[0296] As seen in FIG. 22 and FIG. 23 according to various embodiments, the wearable electronic device (200) can distinguish pressure according to finger size or pressure according to user activity based on distance information obtained through the distance detection sensor (333) (e.g., distance between one side of at least part of the housing (201) and the other side of at least part of the housing (201)). When the wearable electronic device (200) confirms that pressure according to finger size has been detected based on the distance information obtained through the distance detection sensor (333), it can provide a notification regarding the removal of the wearable electronic device so that the user does not feel pain in the finger wearing the wearable electronic device.

[0297] FIG. 24 is a drawing for explaining a method of providing a notification according to one embodiment of the present disclosure.

[0298] Referring to FIG. 24, a wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2 to 4) may output a notification related to the removal of the wearable electronic device (200) when it is predicted that the swelling level of the finger exceeds a first specified swelling level, or that the amount of swelling change exceeds a specified amount of swelling change, and that the swelling level exceeds a second specified swelling level within a specific time.

[0299] This is not limited thereto, and if the wearable electronic device (200) is connected to the first external electronic device (2400) in communication, it may output a notification related to the removal of the wearable electronic device (200) through the first external electronic device (2400). For example, if the wearable electronic device (200) predicts that the swelling level of the finger exceeds a first specified swelling level, or that the amount of swelling change exceeds a specified amount of swelling change, and that the swelling level exceeds a second specified swelling level within a specific time, the wearable electronic device (200) may transmit a signal to the first external electronic device (2400) requesting the output of a notification related to the removal of the wearable electronic device (200). Based on receiving a signal from the wearable electronic device (200) requesting the output of a notification related to the removal of the wearable electronic device (200), the first external electronic device (2400) of FIG. 24 <2410> As illustrated in the figure, a user interface (2415) containing a notification regarding the removal of the wearable electronic device (200) can be displayed on a display (e.g., the display module (160) of FIG. 1). For example, the user interface (2415) containing a notification regarding the removal of the wearable electronic device (200) may include a graph (2420) indicating swelling of the user's finger in relation to the female cycle and information (2425) analyzing the swelling of the user's finger. However, it is not limited thereto.

[0300] In one embodiment, when a situation in which the width of the finger has increased rather than swelling of the finger (e.g., a situation in which the width of the finger increases due to weight gain or loss, or a situation in which the width of the finger increases due to growth) is detected, the wearable electronic device (200) may provide a notification suggesting a size exchange of the wearable electronic device (200) (e.g., a notification suggesting the wearing of a wearable electronic device (200) that is one size larger (or one size smaller). For example, if the wearable electronic device (200) changes the minimum pressure value for a certain period but the pressure value does not drop and remains constant for a certain period, it may determine that the width of the finger has increased rather than swelling of the finger and provide a notification suggesting a size exchange of the wearable electronic device (200).

[0301] It is not limited thereto, and when the wearable electronic device (200) is connected to the first external electronic device (2400) via communication, it may output a notification suggesting a size exchange of the wearable electronic device (200) through the first external electronic device (2400). For example, if the wearable electronic device (200) detects a situation where the width of the finger has increased rather than swelling of the finger (e.g., a situation where weight has been gained or lost, or a situation where the width of the finger increases due to growth), it may transmit a signal to the first external electronic device (2400) requesting the output of a notification suggesting a size exchange of the wearable electronic device (200). Based on receiving the signal requesting the output of a notification suggesting a size exchange of the wearable electronic device (200), the first external electronic device (2400) of FIG. 24 <2450> As illustrated in the figure, the wearable electronic device (200) may display a user interface (2455) on the display (160) that includes a notification suggesting a size exchange of the wearable electronic device (200). For example, the user interface (2455) that includes a notification suggesting a size exchange of the wearable electronic device (200) may include a graph (2460) indicating the condition of the user's finger and information (2465) suggesting a size exchange of the wearable electronic device (200). However, it is not limited thereto.

[0302] FIG. 25 is a drawing for explaining a method of providing a notification according to one embodiment of the present disclosure.

[0303] Referring to FIG. 25, a wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2 to 4) can determine a type of movement based on movement information of the wearable electronic device (200) and information from a plurality of pressure sensors. For example, the wearable electronic device (200) can measure a change in movement of the wearable electronic device (200) based on movement information of the wearable electronic device (200) through a motion sensor (e.g., the motion sensor (335) of FIG. 3). The wearable electronic device (200) can measure a change in a plurality of pressure values ​​based on information from a plurality of pressure sensors obtained through a plurality of pressure sensors (e.g., the pressure sensor (331) of FIG. 3, the plurality of pressure sensors (410) of FIG. 4). For example, the multiple pressure sensor information may include multiple pressure values ​​obtained through multiple pressure sensors (e.g., pressure sensor (331) of FIG. 3, multiple pressure sensors (410) of FIG. 4) at specified time intervals (or specified periods).

[0304] In one embodiment, a memory (e.g., memory (320) of FIG. 3) may store a learning model for each exercise type that has learned changes in pressure values ​​and / or changes in movement according to the movement of each exercise type. Exercise types may include bodyweight exercises (e.g., push-ups, mountain climbers, sit-ups), equipment exercises (e.g., rowing machine, pull-ups, bench press), and / or ball sports (e.g., golf, baseball, tennis). However, they are not limited thereto.

[0305] In one embodiment, the wearable electronic device (200) can determine an exercise type corresponding to changes in movement of the wearable electronic device (200) and changes in a plurality of pressure values ​​based on an exercise type-specific learning model stored in memory (320). The wearable electronic device (200) can provide information related to the determined exercise type. For example, the information related to the exercise type may include count information (e.g., push-up count information, sit-up count information) and / or posture guide information based on movement information and / or pressure values ​​according to the exercise performance.

[0306] This is not limited thereto, and if the wearable electronic device (200) is communicationally connected with a second external electronic device (2500) (e.g., a smart watch), it may also provide information related to the exercise type through the second external electronic device (2500). For example, the wearable electronic device (200) may transmit a signal requesting the output of information related to the exercise type to the second external electronic device (2500). Based on receiving the signal requesting the output of information related to the exercise type from the wearable electronic device (200), the second external electronic device (2500) of FIG. 25 <2510> and <2530> As illustrated in the figure, a user interface (2515, 2535) containing information related to an exercise type can be displayed on a display (e.g., the display module (160) of FIG. 1). For example, the user interface (2515, 2535) containing information related to an exercise type may include exercise time information, calorie information, and / or count information (e.g., number of repetitions, sets). However, it is not limited thereto.

[0307] In one embodiment, information related to the type of exercise may include information on the risk of finger injury. For example, the wearable electronic device (200) may analyze whether the exercise is strenuous on the finger or hand based on movement information and / or pressure values ​​during exercise performance, and provide information related to the type of exercise, for example, information on the risk of finger injury, to the user.

[0308] This is not limited thereto, but if the wearable electronic device (200) is communicationally connected with a second external electronic device (2500) (e.g., a smart watch), it may provide information related to the type of exercise, for example, information on the risk of finger injury, through the second external electronic device (2500). For example, the wearable electronic device (200) may transmit a signal requesting the output of information on the risk of finger injury to the second external electronic device (2500). Based on receiving the signal requesting the output of information related to the type of exercise, for example, information on the risk of finger injury, from the wearable electronic device (200), the second external electronic device (2500) of FIG. 25 <2550> As illustrated in [Image], a user interface (2555) containing information related to the type of exercise, for example, information on the risk of finger injury, can be displayed on the display (160).

[0309] As seen in FIG. 24 and FIG. 25 according to various embodiments, when communication is connected with at least one external electronic device, the user can intuitively check the current state (e.g., finger state, exercise state) by providing a notification related to the removal of the wearable electronic device, information suggesting a size exchange of the wearable electronic device (200), or information related to the type of exercise through at least one external electronic device.

[0310] FIG. 26 is a drawing illustrating user input for executing a specific function as an example of pressure by user activity according to one embodiment of the present disclosure.

[0311] In FIG. 12 and FIG. 25 according to various embodiments, information related to the type of exercise based on the pressure from the user's exercise is described as an example of pressure from the user's activity, but is not limited thereto. For example, the pressure from the user's activity may include user input for executing a specific function.

[0312] For example, referring to FIG. 26, a wearable electronic device (e.g., the electronic device (101) of FIG. 1, the wearable electronic device (200) of FIG. 2 to 4) may be worn on a user's finger (2610). The wearable electronic device (200) may detect user input on the outer surface of the housing of the wearable electronic device (200) (e.g., the housing (201) of FIG. 2) while the wearable electronic device (200) is worn on the user's finger (2610) (e.g., the surface that does not come into contact with the finger when the wearable electronic device (200) is worn on the user's finger (e.g., the outer surface). For example, user input may include pressure (e.g., force) applied to the outer surface of the housing (201) of the wearable electronic device (200) by the user's other finger. For example, a specific function that is performed when pressure (e.g., force) is applied to the outer surface of the housing (201) of the wearable electronic device (200) may be pre-set. For example, the specific function may include a biometric information measurement function, a pairing function with at least one external electronic device (e.g., the first external electronic device (2400) of FIG. 24, the second external electronic device (2500) of FIG. 25), or a payment function. However, it is not limited thereto.

[0313] For example, when pressure (e.g., force) is applied from the outside of the wearable electronic device (200) toward the inside of the wearable electronic device (200) (e.g., the opening (2001) in FIG. 2) (e.g., 461 and / or 463 in FIG. 4), one pressure value (or at least two pressure values) among a plurality of pressure values ​​measured through a plurality of pressure sensors (e.g., the plurality of pressure sensors (410) in FIG. 4) may differ from at least two other pressure values ​​(e.g., at least three other pressure values). In this case, the wearable electronic device (200) may detect pressure caused by user activity, for example, user input to execute a specific function, and may perform said specific function mapped to the user input.

[0318] A method for detecting a change in finger size according to one embodiment may include an operation of checking whether the level of swelling of the finger is predicted to exceed a second specified level of swelling within a specific time when the level of swelling of the finger exceeds a first specified level of swelling, or when the amount of change in swelling based on the user's swelling data stored in memory (320) exceeds a specified amount of change in swelling. A method for detecting a change in finger size according to one embodiment may include an operation of outputting a notification related to the removal of the wearable electronic device (200) when it is predicted that the level of swelling of the finger exceeds the second specified level of swelling within a specific time.

[0319] Each of the plurality of pressure sensors (331, 410) according to one embodiment may be positioned in close proximity to one of the connector (425), charging circuit (420), optical sensor (250a, 250b, 250c), and battery (189) of the wearable electronic device (200).
