[0048] Hereinafter, embodiments will be described in detail with reference to the attached drawings. In the description with reference to the attached drawings, identical components are assigned the same reference numerals regardless of the drawing numbers, and redundant descriptions thereof will be omitted.

[0049] FIG. 1 is a drawing for explaining an electronic device according to one embodiment.

[0050] Referring to FIG. 1, an electronic device (110) may include a processor (111) and a memory (112). Only components related to the present embodiments are illustrated in the electronic device (110) illustrated in FIG. 1. It will be apparent to those skilled in the art that the electronic device (110) may further include other general components in addition to the components illustrated in FIG. 1.

[0051] The processor (111) may perform an overall function for controlling the electronic device (110). The processor (111) may control the electronic device (110) overall by executing programs and / or instructions stored in the memory (112). The processor (111) may be implemented as a central processing unit (CPU), a graphics processing unit (GPU), an application processor (AP), etc., provided in the electronic device (110), but is not limited thereto.

[0052] The memory (112) may be hardware that stores data processed and data to be processed within the electronic device (110). In addition, the memory (112) may store applications, drivers, etc. to be driven by the electronic device (110). The memory (112) may include volatile memory such as dynamic random access memory (DRAM) and / or nonvolatile memory.

[0053] A body composition measurement device (120) may refer to a device that measures and analyzes the body composition of a subject. The body composition measurement device (120) may have various structures and shapes for measuring the body composition of a subject. For example, the body composition measurement device (120) may measure body composition using a plurality of electrodes attached to or in contact with the body of the subject.

[0054] Body composition analysis or body composition measurement may be the analysis of the components of the body of the subject or the ratio between the components using physical quantities determined from the body of the user of the electronic device (110) or the subject. Measurement may refer to obtaining a physical quantity using a measuring device. Measurement may also include the process of processing the physical quantity to obtain another type of physical quantity. For example, applying current to two points on the body and measuring the voltage difference with a voltmeter is also called measurement, and further, calculating the impedance between two points on the body based on the applied current value and voltage difference can also be called measurement.

[0055] The electronic device (110) may include, but is not limited to, various computing devices such as mobile phones, smart phones, tablets, e-book devices, laptops, personal computers, desktops, workstations, or servers, various wearable devices such as smart watches, smart glasses, HMDs (Head-Mounted Displays), or smart clothing, various home appliances such as smart speakers, smart TVs, or smart refrigerators, smart cars, smart kiosks, IoT (Internet of Things) devices, WADs (Walking Assist Devices), drones, or robots.

[0056] The electronic device (110) can be connected to the body composition measurement device (120) by wire or wirelessly, and can transmit and receive data. For example, the electronic device (110) can receive data on the body composition of the subject from the body composition measurement device (120). In addition, the electronic device (110) can transmit a command to the body composition measurement device (120) to measure the body composition of the subject. In FIG. 1, the electronic device (110) is illustrated as a device provided separately from the body composition measurement device (120), but depending on the embodiment, the electronic device (110) may be included in the body composition measurement device (120).

[0057] According to one embodiment, the electronic device (110) may determine the difference in body composition of each body part of the subject based on the body composition measured for each body part. In addition, the electronic device (110) may determine a change in the body composition difference by accumulating the body composition differences of the body parts. For example, the electronic device (110) may determine the difference in swelling due to swelling between the healthy side and the affected side of a subject with edema (e.g., a lymphedema patient, a cancer patient, a chronic disease patient, or a rehabilitation patient) and provide the change in the difference in swelling to the subject. For example, cancer patients may include breast cancer patients, gynecological cancer patients, or prostate cancer patients, and chronic disease patients may include heart failure patients, diabetes patients, or renal failure patients.

[0058] According to one embodiment, the electronic device (110) can synchronize the activity events of the examinee with changes in body composition differences and provide them together with the changes in body composition differences. Furthermore, the electronic device (110) can determine feedback capable of reducing the body composition differences of the examinee based on the changes in body composition differences and / or activity events, and provide the determined feedback to the examinee. For example, the electronic device (110) can provide lifestyle correction methods and self-management methods suitable for the examinee individually based on the changes in body composition differences and activity events of the examinee with edema. Through this, the user of the electronic device (110) or the examinee can record lifestyle habits or self-management along with changes in body composition differences, and use this as a reference for more accurately correcting lifestyle habits.

[0059] FIG. 2 is a diagram for explaining a body composition measurement process of an electronic device according to one embodiment.

[0060] Referring to FIG. 2, operations for measuring body composition using a body composition measuring device and providing measurement results are exemplarily illustrated. Operations (210) to (250) may be performed by the electronic device or the body composition measuring device.

[0061] In operation (210), the electronic device or body composition measurement device may provide guidance for beginning body composition measurement of the subject. For example, the electronic device or body composition measurement device may provide guidance regarding the placement of the body composition measurement device, the measurement posture (e.g., positioning of the feet and hands), and the preparation process for measurement to ensure accurate body composition measurement. The guidance may be provided to the subject through an application provided by the electronic device or through the display of the body composition measurement device.

[0062] In operation (220), the electronic device may cause the body composition measurement device to adjust the zero point for body composition measurement. For example, the electronic device may guide the subject to a motion for adjusting the zero point for body weight, and in response to performing the motion, cause the body composition measurement device to adjust the zero point. For example, the electronic device may provide guidance to the subject to press the foot pedal of the body composition measurement device once and confirm the zero point.

[0063] In operation (230), the electronic device can measure the body composition and weight of the subject using a body composition measurement device. During body composition measurement, the electronic device can provide guidance to the subject to maintain a posture and keep their body in contact with the electrodes of the body composition measurement device. The measured weight can be used to measure the body composition of the subject.

[0064] In operation (240), the electronic device may analyze the measurement results based on the measured body components. In one embodiment, the electronic device may determine differences in body composition between body parts of the subject based on the measured body components. The operation of the electronic device analyzing the measurement results is described in detail below in FIG. 3.

[0065] In operation (250), the electronic device can provide the analyzed measurement results to the subject through an application provided by the electronic device or a display of the body composition measurement device. The subject can check the measurement results analyzed by the electronic device.

[0066] Figure 3 is a flowchart illustrating an operating method of an electronic device according to one embodiment.

[0067] In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Operations (310) and (320) may be performed by at least one component (e.g., a processor, etc.) of the electronic device.

[0068] In operation (310), the electronic device can measure the body composition of each body part of the subject. The body parts may include both arms or both legs of the subject. The subject may be a patient with lymphedema, a patient with cancer (e.g., breast cancer, gynecological cancer, or prostate cancer), a patient with a chronic disease (e.g., heart failure, diabetes, or renal failure), or a patient undergoing rehabilitation.

[0069] In operation (320), the electronic device can determine the difference in body composition of body parts based on the measured body components. The electronic device can determine the difference in at least one of extracellular water ratio, muscle mass, and body water content of body parts based on the measured body components. The electronic device can determine the difference in body composition of body parts by subtracting one body component from another body component. The electronic device can determine the difference in swelling of body parts based on the difference in body composition of body parts.

[0070] An electronic device can accumulate determined body composition differences and determine changes in body composition differences of body parts over time. The electronic device can receive information about activity events from the subject, synchronize the activity events with changes in body composition differences, and provide the changes along with the changes in body composition differences. Based on the changes in body composition differences and the activity events, the electronic device can provide feedback to the subject that can reduce the body composition differences of the subject. The electronic device can determine the influence of activity events on changes in body composition differences and, based on the determination results, determine and provide feedback to the subject that can reduce the body composition differences of the subject.

[0071] FIG. 4 is a diagram for explaining an operation of providing information on body composition differences according to one embodiment.

[0072] Referring to FIG. 4, an electronic device can measure and analyze differences in the body composition of a subject and provide information on the differences in body composition to the subject. In the measurement results (400) of FIG. 4, information on differences in body composition (410, 420, 430, 440) provided by the electronic device are exemplarily illustrated.

[0073] The measurement result (400) may be provided to the subject, for example, through an application provided by an electronic device or a display of a body composition measurement device. The measurement result (400) may include information (410, 420, 430, 440) regarding the difference in the body composition of the subject. However, this is merely an example for explanation, and the embodiment is not limited thereto, and may further include various pieces of information.

[0074] Information (410) may indicate the body part where the body composition measurement was performed. The electronic device may provide information on the difference in body composition between the affected body part and the healthy body part. For example, in the case of a breast cancer patient, lymphedema may occur due to damage to the lymph nodes in the affected arm during breast cancer surgery to prevent metastasis. In this case, the electronic device may measure swelling due to swelling in the affected arm and the healthy arm and provide information on the difference in body composition between the affected arm and the healthy arm so as to monitor how much the affected arm is swollen compared to the healthy arm. The difference in body composition may indicate a difference in at least one of, for example, extracellular water ratio, muscle mass, and body water content. The electronic device may determine the difference in swelling between both arms or both legs based on the body composition difference. The body composition difference may include the determined difference in swelling.

[0075] Information (420) may indicate the level of body composition of the affected body part. The electronic device may classify the body composition of the affected body part into one of predetermined level ranges. The predetermined level ranges may include a good range indicating the normal range of body composition and a caution range indicating an abnormal range. For example, the electronic device may display the extracellular water ratio of the affected arm of the subject as one of the predetermined level ranges. Through this, the subject or user can conveniently and intuitively check the current status of the body composition of the affected body part.

[0076] Information (430) may indicate changes in body composition differences between the affected body part and the healthy body part. The electronic device may accumulate the determined body composition differences to determine changes in body composition differences between the body parts over time. For example, the electronic device may determine changes in body composition differences between the affected body part and the healthy body part based on the measured time or date. For example, the electronic device may output the measured body composition differences between the affected body part and the healthy body part as a graph over time. For example, the electronic device may provide information (430) to monitor whether the difference in swelling due to the difference in extracellular water ratio between the affected arm and the healthy arm is satisfactory.

[0077] Information (440) may indicate markers for the subject's activity events or body composition measurements. The subject can check the body composition status or activity events at a given time or date through the markers.

[0078] FIG. 5 is a diagram illustrating an operation for providing feedback according to one embodiment.

[0079] Referring to FIG. 5, the electronic device provides feedback (510) according to the change in body composition of the subject in the output result (500) as an example.

[0080] The electronic device may provide feedback (510) to the subject that can reduce the body composition difference of the subject based on changes in body composition difference and / or activity events. The electronic device may analyze the accumulated body composition difference changes based on cutoffs for changes in body composition difference and cutoffs for absolute values, thereby determining feedback (510) that can reduce the body composition difference of the subject.

[0081] For example, if the change in body composition difference of the affected body part is greater than or equal to a predetermined reference value (e.g., three or more changes due to food intake), the electronic device may provide a notification about the change in body composition difference and determine feedback (510) that can reduce the body composition difference. The feedback (510) may be determined based on an activity event that affected the improvement in the body composition difference of the affected body part. In addition, the electronic device may determine feedback (510) that can reduce the body composition difference of the subject when at least one of the following occurs: the absolute value of the extracellular water ratio of the affected body part is greater than or equal to a predetermined reference value; the difference in extracellular water ratio between the affected body part and the healthy body part is greater than or equal to a predetermined reference value; and the difference between the current and immediately preceding extracellular water ratio results is greater than or equal to a predetermined reference value. In addition, the electronic device may determine feedback (510) that can reduce the body composition difference of the subject when the amount of change in the body composition difference of the subject is greater than or equal to a body composition difference of a normal person. Alternatively, the electronic device may determine feedback (510) when the change in body composition difference of the subject is greater than a predetermined standard value (e.g., +0.003 based on the extracellular water ratio) compared to the change in body composition difference of a normal person.

[0082] In one embodiment, the electronic device may select one of the predefined feedbacks based on the subject's disease or symptoms, or may use artificial intelligence (AI) pre-trained on disease and body composition differences to determine the feedback (510). For example, the electronic device may provide feedback (510) regarding lifestyle recommendations to reduce swelling caused by edema in the affected body part, or recommendations for continuous body composition measurement.

[0083] FIG. 6 is a diagram for explaining an operation that provides a change in body composition difference according to one embodiment.

[0084] Referring to FIG. 6, the electronic device can determine a measured body composition difference change (610) for a specific period of time.

[0085] For example, in breast cancer patients, lymphedema often develops within a year, but it can also develop after 10 years.

[0086] In one embodiment, the electronic device may provide a graph of measured body composition differences (610) over a period set by the user or subject. For example, the electronic device may provide long-term body composition differences (610) over a period of time, such as a year. Furthermore, since the subject may not be aware of worsening symptoms, when providing long-term body composition differences (610), the electronic device may also provide feedback recommending continued body composition measurement and testing.

[0087] Alternatively, according to an embodiment, the electronic device may determine a period (e.g., 1 year, 10 years) for displaying body composition difference changes (610) based on the disease or symptom of the subject, and provide the body composition difference changes (610) for the corresponding period to the subject.

[0088] FIG. 7 is a drawing for explaining an operation of providing a change in body composition difference using a marker according to one embodiment.

[0089] Referring to FIG. 7, the electronic device can synchronize the subject's activity events with changes in body composition differences and present them together. For example, the electronic device can display activity events along with changes in body composition differences on the same time axis.

[0090] In the measurement results (710), the electronic device may provide markers indicating activity events along with changes in the subject's body composition. For example, the activity event may include at least one of physical activity, exercise, massage, diet, lifestyle habits, self-care, and treatment. The markers may be displayed in different forms depending on the activity event. The user may select one or more markers provided by the electronic device.

[0091] In the measurement result (720), the electronic device may display an activity event corresponding to the marker (725) around the marker (725) in response to the user selecting the marker (725). For example, the electronic device may display exercise history corresponding to the marker (725). Furthermore, the electronic device may synchronize the activity event corresponding to the marker (725) with the measurement result (720) in response to the user selecting the marker (725). The electronic device may display the measurement result of the body composition difference measured immediately after the activity event corresponding to the marker (725). Through this, the electronic device may easily confirm whether the activity event had any effect on the body composition difference of the subject immediately afterward. The electronic device may determine the effect of the activity event on the change in body composition difference, and based on the determination result, determine and provide feedback that can reduce the body composition difference of the subject to the test. For example, if a subject's body composition difference decreases more significantly after a specific activity event than after other activity events, the electronic device may determine that the activity event has had a positive impact on body composition changes. Based on this determination, the electronic device may then provide feedback to the subject encouraging continued performance of the activity event.

[0092] In the measurement result (730), the electronic device may display one or more markers included in the measurement result section in response to the user selecting a marker (725) included in the specific measurement result section. The markers may correspond to each activity event of the test subject entered in the corresponding measurement result section. For example, in the measurement result (730) displayed at equal intervals, the electronic device may expand and display the specific measurement result section in response to the user selecting a marker (725) included in the specific measurement result section, and display one or more markers in the expanded measurement result section. The user may select one or more target markers (735) for which he or she wishes to check the activity event among the displayed one or more markers. The electronic device may expand and display the measurement result section whenever the user selects one or more target markers (735), and display an activity event corresponding to each target marker (735). Alternatively, the electronic device may display activity events corresponding to one or more target markers (735) together in response to the user selecting one or more target markers (735).

[0093] FIG. 8 is a diagram for explaining an operation of providing a change in body composition difference according to a time interval according to one embodiment.

[0094] Referring to FIG. 8, the electronic device may provide a pinch zoom function for measurement results (810, 820) to provide changes in body composition of the subject over time. The pinch zoom function may include a zoom in function that enlarges the measurement result (810) when the distance between two points input to the electronic device increases, and a zoom out function that reduces the measurement result (810) when the distance between the two points decreases. Here, the two points input to the electronic device may be input by a user's touch on a display connected to the electronic device, for example.

[0095] In response to a zoom-in input from a user, the electronic device may enlarge the measurement result (810) and reduce the time interval of the displayed measurement result (810). For example, the electronic device may reduce the time interval of the displayed measurement result (810) to provide weekly body composition difference changes for the subject.

[0096] In response to a zoom-out input from a user, the electronic device may reduce the measurement result (810) and expand the time interval of the displayed measurement result (810). For example, the electronic device may expand the time interval of the displayed measurement result (810) to provide a measurement result (820) representing the annual body composition difference change of the subject.

[0097] The electronic device may provide measurement results (810) at different time intervals depending on the distance between two points or the speed at which the two points move when pinch zoom is input. For example, the electronic device may provide changes in the body composition of the subject over a daily, weekly, monthly, annual, or 10-year period, but the embodiment is not limited thereto. In addition, the electronic device may provide measurement results (810) for a time interval corresponding to the location where pinch zoom is input by enlarging or reducing them.

[0098] Additionally, the electronic device may determine feedback differently depending on the time interval at which the measurement results (810) are provided. For example, when providing short-term measurement results (810), the electronic device may provide short-term, recommended feedback to the subject to reduce body composition differences. Alternatively, when providing long-term measurement results (810), the electronic device may provide long-term, recommended feedback to the subject to reduce body composition differences.

[0099] FIG. 9 is a diagram for explaining an operation of providing information on body composition according to one embodiment.

[0100] Referring to FIG. 9, the electronic device can measure the body composition (910) of each body part of the subject and provide information about the body composition (910) of the subject.

[0101] In one embodiment, the electronic device may measure at least one of the subject's body weight, skeletal muscle mass, body fat percentage, and visceral fat level, and provide the subject with the measurement results (920). For example, the electronic device may provide information on body composition (910) along with differences in swelling based on differences in body composition of the subject's body parts.

[0102] Additionally, the electronic device can provide the subject's body composition along with the standard range for body composition of a normal person. The electronic device can determine the body composition that must change for the subject's body composition to fall within the standard range and provide the determined body composition to the subject. For example, the electronic device can determine the amount of weight that must increase or decrease for the subject's weight to fall within the standard range and provide the determined weight in the measurement result (920). Furthermore, the electronic device can determine the skeletal muscle mass or body fat percentage that must change for the subject's skeletal muscle mass or body fat percentage to fall within the standard range after surgery. Through this, the electronic device can help not only reduce body composition differences between body parts of the subject but also ensure that the body composition falls within the standard range. For example, proper body fat management after breast cancer surgery can help prevent complications.

[0103] Fig. 10 is a diagram for explaining an operation of receiving an activity event according to one embodiment.

[0104] Referring to FIG. 10, an electronic device can receive an activity event from a user. In FIG. 10, screens (1010, 1020, 1030) through which the electronic device receives an activity event from a user are exemplarily illustrated.

[0105] On screen (1010), the electronic device may receive an activity event input request from a user. For example, the electronic device may receive the activity event input request in response to the user clicking an "Add Record" button displayed on screen (1010).

[0106] On screen (1020), the electronic device may receive an input of a type of activity event (e.g., food, exercise, compression therapy, self-diagnosis) in response to receiving an activity event input request. The electronic device may display predetermined types of activity events and receive an input of any one of the predetermined types from the user.

[0107] On the screen (1030), the electronic device may, in response to receiving input from the user of one of the predetermined types of activity events, provide an information input field for the activity event for the input type. Through the information input field, the electronic device may receive input of information about the activity event from the user. For example, the electronic device may receive input of activity content (e.g., meal content, exercise content, treatment content) and activity time from the user. For example, in the case of compression therapy, the electronic device may receive input of at least one of the treatment date and time, treatment type, compression intensity, treatment range, and duration. The user may input activity events multiple times a day at desired time periods and compare the results with the lifestyle habits before and after body composition measurement.

[0108] FIG. 11 is a diagram illustrating an operation of synchronizing an activity event to a change in body composition difference according to one embodiment.

[0109] Referring to FIG. 11, the electronic device can synchronize activity events with changes in body composition differences and provide them together with changes in body composition differences.

[0110] The electronic device may receive information about an activity event from an information input field provided on the screen (1110) and synchronize the activity event with a change in body composition difference based on the information entered on the screen (1120). For example, the electronic device may synchronize the activity event with a change in body composition difference by listing the activity event and the body composition measurement time in chronological order in the measurement result (1125). On the screen (1130), the electronic device may display the synchronized activity event and the change in body composition difference by adjusting the time interval in response to a pinch zoom input from the user.

[0111] FIG. 12 is a diagram for explaining an operation of providing a trend for body composition differences according to one embodiment.

[0112] Referring to FIG. 12, an electronic device can provide trends regarding differences in body composition of a subject. In FIG. 12, screens (1210, 1220, 1230) on which the electronic device provides trends regarding differences in body composition of a subject are exemplarily illustrated.

[0113] On screen (1210), the electronic device can determine whether there is sufficient information regarding the subject's body composition differences. For example, the electronic device can determine whether the subject's body composition difference measurement results exceed a predetermined number (e.g., three per week). If the electronic device determines that there is insufficient information regarding the subject's body composition differences, it may not provide trends regarding the subject's body composition differences.

[0114] On screen (1220), if the electronic device determines that there is sufficient information regarding the body composition difference of the subject, the electronic device may provide a trend of the body composition difference of the subject. For example, the electronic device may provide a trend line of the body composition difference for a predetermined time interval (e.g., 1 week, 1 month). The electronic device may determine the trend line of the body composition difference for the predetermined time interval based on the first and last data of the body composition difference for the predetermined time interval. Furthermore, the electronic device may provide feedback that can reduce the body composition difference based on the determined trend of the body composition difference.

[0115] On screen (1230), if the electronic device determines that there is sufficient information regarding the difference in body composition of the subject, it may provide an average level of body composition of the affected body part of the subject. The electronic device may determine the average level by determining the average of the levels of body compositions of the affected body part determined over a predetermined time period. Furthermore, the electronic device may provide feedback that can reduce the body composition difference based on the determined average level of body composition of the affected body part.

[0116] FIG. 13 and FIG. 14 are drawings for explaining an operation of providing a notification message according to one embodiment.

[0117] Referring to FIG. 13, the electronic device may provide a notification message (1325) regarding a change in body composition difference to the subject or user based on the measurement result (1315) of the screen (1310). The notification message (1325) may be provided through a nudge on the screen (1320) of the terminal used by the subject or user.

[0118] According to one embodiment, the electronic device may determine a notification message (1325) based on an activity event and / or a change in body composition difference. Furthermore, the electronic device may determine the notification message (1325) based on a cutoff for a change in body composition difference and / or a cutoff for an absolute value. The notification message (1325) may be, for example, related to a recommendation for periodic body composition measurement, a recommendation for an activity event, a body composition measurement guide, a self-treatment guide, or a lifestyle habit correction. For example, if the electronic device determines that more periodic body composition measurement is required based on an activity event and / or a change in body composition difference, the electronic device may provide a body composition measurement notification to the subject. Furthermore, if the subject measures body composition at a different time than usual, the electronic device may provide a notification regarding a measurement guide for accurate body composition measurement to the subject.

[0119] Referring to FIG. 14, an example of a notification message (1400) regarding a change in body composition difference is illustrated.

[0120] For example, the notification message (1400) may correspond to a notification regarding a self-treatment method. For example, if the electronic device determines that swelling of the affected body part has increased compared to the healthy body part after the subject has performed compression treatment with compression stockings, the electronic device may provide the subject with a notification to perform compression treatment using a bandage for more appropriate treatment.

[0121] FIG. 15 is a diagram for explaining an operation of providing a notification message to a guardian according to one embodiment.

[0122] Referring to FIG. 15, the electronic device may provide a notification message (1525) regarding changes in the body composition of the subject to the screen (1520) of a terminal used by the subject's guardian. For example, the notification message (1525) may be provided as a nudge on the screen (1520) of the terminal used by the guardian, or may be provided through an application.

[0123] According to one embodiment, the subject or user can set whether to notify the guardian. For example, the subject or user can set whether to notify the guardian through the settings button (1515) on the screen (1510). Depending on whether the guardian is notified, the electronic device can provide the guardian with a notification message (1525) regarding changes in the subject's body composition. The electronic device can determine the notification message (1525) based on the subject's activity events and / or changes in body composition. For example, if the subject's body composition requires attention, the electronic device can provide the guardian with a notification to notify the subject of the need to manage the body composition.
