[0002] With the development of the times, in the era of health consumption, people's demand for weight scales is not limited to measuring body weight. As people's understanding of health knowledge becomes deeper and deeper, body fat percentage has become an important indicator for people who seek health to understand their own health level. Therefore, people's demand for body fat scales is also increasing.

[0003] In the related art, it is common to measure the human body fat content by the bioelectrical impedance method, which essentially calculates the human body fat content by emitting a weak current from an electrode and introducing the current into the body to measure the impedance. For example, when using a body fat scale, a person can complete a body fat test by simply standing barefoot on the cross electrode area on the surface of the body fat scale.

[0030] Hereinafter, the technical means in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and obviously, the described embodiments are only a part of the embodiments of the present application, and are not all of the embodiments. Based on the embodiments of the present application, all other embodiments that a person skilled in the art can obtain without creative efforts are all within the scope of protection of the present application.

[0031] In this specification, the term "and / or" merely describes the related relationship of related objects and indicates that three types of relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In this specification, the character " / " generally indicates that the related objects before and after it are in an "or" relationship. In this specification, the character "multiple" indicates two or more. In this specification, the term "at least one" represents any combination of at least two of any one or more of the multiple types. For example, including at least one of A, B, and C can represent including any one or more elements selected from the set consisting of A, B, and C.

[0032] The control method of the present application is mainly applied to related weighing devices, such as a body fat scale, which identifies a user's foot motion and realizes the user's control over the user display screen of the body fat scale based on the foot motion.

[0033] Currently, the way in which a user controls a body fat scale is mainly that the user downloads the corresponding APP from the corresponding official website according to the type of body fat scale to the mobile phone and controls the body fat scale through the APP, but the user can only view various data measured by the APP independently, or can only perform simple operations such as on / off based on the buttons on the body fat scale, and cannot realize more appropriate control operations. Therefore, when controlling the user display screen of a body fat scale using the conventional control method, the user cannot directly operate the user display screen of the body fat scale with the limbs, but must download the APP and operate it through the mobile phone when using it. This increases the complexity of the interaction process, greatly increases the difficulty of using the body fat scale, and greatly affects the user's experience. Based on this, the present application provides a method for controlling the user display screen of a body fat scale, and the technical means used in the present application will be described in detail below.

[0034] Please refer to FIG. 1. FIG. 1 is a flowchart of an embodiment of a method for controlling a user display screen of a body fat scale according to the present application.

[0035] In step 11, the user's foot motion is identified in the wake-up state.

[0036] Specifically, the body fat scale enters the wake-up state by determining that both feet of the user are standing on the body fat scale. For example, after the body fat scale is turned on and started, it is determined whether both feet of the user are standing on the body fat scale, and if both feet of the user are standing on the body fat scale, the body fat scale enters the wake-up state, and in the wake-up state, the user may control the user display screen of the body fat scale based on the foot movement. In this embodiment, by identifying the foot movement of the user in the wake-up state, it is possible to avoid detection that occurs when some kind of erroneous operation or an object is dropped on the body fat scale.

[0037] The wake-up state indicates that the body fat scale is currently in a queued operating state, and the processor of the body fat scale is running and can perform corresponding operations after receiving a command.

[0038] Preferably, after detecting that there is a weight change in the body fat scale, the body fat scale passes a safety current through the object to measure the impedance of the object. If the impedance is within a predetermined impedance magnitude range, it is confirmed that a human is standing on the body fat scale. This further prevents an object similar to a human weight from falling onto the body fat scale and causing a false detection. The predetermined impedance magnitude range may be set based on an average impedance range of a human body before shipping the body fat scale.

[0039] In one embodiment of the present application, the body fat scale acquires a weight change amount of a user, and in response to the weight change amount being within a predetermined range, determines that both feet of the user are standing on the body fat scale. The size of the predetermined range may be set before shipment, or may be set by the user according to the needs of the user, for example, the actual weight of the user, and is not limited herein. In this embodiment, by determining whether both feet of the user are standing on the body fat scale based on the weight change amount of the user, the wake-up state is entered, so that it is possible to avoid interference caused by the user touching the body fat scale with one foot or placing another object on the body fat scale, and it is possible to improve the control accuracy of the body fat scale entering the wake-up state.

[0040] After entering the wake-up mode, the body fat scale opens the user display screen, and identifies the user's foot motion when the user display screen is in a display state. In this manner, the body fat scale first opens the user display screen, initializes the user display screen, and then identifies the user's foot motion, making it easy for the user to control the user display screen based on the content of the user display screen, which not only improves the user experience, especially the experience of a beginner of the body fat scale, but also improves the accuracy of controlling the user display screen.

[0041] Preferably, a display or the like is provided in the body fat scale, and the user display screen may be displayed on the display. Alternatively, a projection device may be provided in the body fat scale, and after entering the wake-up mode, the body fat scale controls the projection device to project the user display screen onto a projection receiving area, such as the ground or a wall surface.

[0042] Preferably, a motion detection sensor is installed in the body fat scale, and in this embodiment, step 11 can be realized by the method shown in FIG.

[0043] In step 21, information about the user's movements on the body fat scale is obtained by the movement detection sensor.

[0044] Specifically, the motion detection sensor includes a vibration sensor, the motion information includes vibration information, and the step of acquiring the motion information of the user on the body fat scale by the motion detection sensor includes the step of acquiring the vibration information by the vibration sensor.

[0045] Specifically, a vibration sensor is a device or element that measures the vibration of an object. The principle is to determine the vibration state of an object by detecting minute displacements or speed changes caused by vibrations on the surface of the object. Vibration sensors include acceleration sensors, piezoelectric sensors, laser interferometers, and the like. When a user performs foot movements on a body fat scale, the user steps on the body fat scale, causing the body fat scale to vibrate. In this embodiment, the body fat scale can accurately obtain information on the user's movements on the body fat scale using the vibration sensor.

[0046] In one embodiment of the present application, the vibration sensor may be an acceleration sensor, and the body fat scale obtains vibration information of the body fat scale through the acceleration sensor. The acceleration sensor is a sensor that detects a vibration situation by measuring the acceleration of an object. The acceleration sensor is usually manufactured using a microelectromechanical system (MEMS), and its operating principle is based on Newton's second law. When the object vibrates, the acceleration sensor measures the acceleration of the object to calculate vibration characteristic parameters of the object, i.e., vibration information.

[0047] In one embodiment of the present application, the vibration sensor may be a piezoelectric sensor. A piezoelectric vibration sensor is a sensor that converts mechanical vibration into an electrical signal, and its operating principle is based on the piezoelectric effect. The piezoelectric effect refers to a phenomenon in which a crystalline material is subjected to mechanical stress, which generates an uneven charge distribution, resulting in a potential difference. By utilizing this effect, the mechanical vibration of an object can be converted into an electrical signal, thereby realizing vibration detection and measurement. A piezoelectric vibration sensor is usually manufactured from a piezoelectric ceramic material, and its structure includes parts such as a vibration sensing element, a signal amplifier, a filter, a microprocessor, and an output interface. When an object vibrates, the vibration sensing element generates a weak electrical signal due to the uneven distribution of minute charges. The signal amplifier amplifies the weak electrical signal, the filter filters out noise and interference signals, and the microprocessor performs digitization processing and analysis on the signal to extract useful vibration characteristic parameters. Finally, the output interface outputs an analog voltage signal or a digital signal for connection to a data collection system or a control system. The piezoelectric vibration sensor has the advantages of high sensitivity, high accuracy, low power consumption, etc., and is suitable for measuring small vibration signals. Piezoelectric vibration sensors are widely used in fields such as vibration monitoring and fault diagnosis of mechanical equipment, vibration monitoring and safety assessment of structures, acoustic vibration monitoring, and non-contact measurement.

[0048] In step 22, the user's foot motion is identified based on the motion information.

[0049] The body fat scale identifies the user's foot motion based on the vibration information. Specifically, the vibration information includes a vibration change amount. In this embodiment, step 22 can be realized by the method shown in FIG. 3, and the method in this embodiment includes steps 31 and 32.

[0050] In step 31, if the vibration change amount is equal to or greater than the vibration sensitivity, it is determined that the user has performed a foot movement.

[0051] When the body fat scale acquires that the amount of vibration change is equal to or greater than the vibration sensitivity, it determines that the user has performed a foot movement.

[0052] Specifically, the vibration sensitivity is used by the body fat scale to determine whether the acquired vibration change amount is equal to the vibration change amount threshold value by the user, and the method of acquiring the vibration sensitivity may be realized by a method of inputting or introducing the vibration sensitivity by the user, or may be extracted from the database of the body fat scale. For example, the vibration sensitivity may be stored in advance in the database of the body fat scale, and the body fat scale can acquire the vibration sensitivity by calling up the database. Of course, the vibration sensitivity may be introduced by the user, or the user may collect the vibration sensitivity in advance and introduce it to the body fat scale. Therefore, there are many methods for acquiring the vibration sensitivity, and no particular limitation is imposed here.

[0053] In step 32, the motion type of the foot action is determined.

[0054] The body fat scale further determines an action type based on the identified user's foot action, and determines the user's specific operation on the user display screen, thereby facilitating the body fat scale to control, such as switching, the user display screen. The body fat scale may store a mapping relationship between the action type and the specific operation on the user display screen in advance or set by the user, and different users may set the mapping relationship based on their own operation habits, which can realize personalized control of the user display screen and improve the user experience, and since the users set the mapping relationship based on their own operation habits, the efficiency of the users controlling the user display screen can be improved.

[0055] In one embodiment of the present application, the body fat scale determines the number of foot steps, which is the number of foot actions that occur within a predetermined time, and determines whether the user's foot action is a single click action or a double click action based on the number of foot steps. The length of the predetermined time may be set before shipment or may be set by the user according to the needs of the user, and is not limited here.

[0056] The body fat scale continuously detects vibration information and determines the number of foot movements based on the amount of vibration change, where the minimum value of the amount of vibration change during one foot movement is equal to or greater than a threshold, and the difference between the sensitivity and the threshold is the vibration fluctuation value of the body fat scale during one foot movement of the user.

[0057] For example, if the specified time is 2 s, if the body fat scale obtains that the user has performed a foot movement multiple times (multiple times includes twice and more than twice) within 2 s, it determines that the user's current foot movement is a double-click movement, and if the body fat scale obtains that the user has performed a single foot movement within 2 s, it determines that the user's current foot movement is a single-click movement.

[0058] In one embodiment of the present application, the body fat scale determines that a foot action is a double click action in response to the interval time between two adjacent foot actions performed by the user being equal to or less than an interval threshold value. The size of the interval threshold value may be set before shipment or may be set by the user according to the needs of the user, and is not limited here.

[0059] For example, when the interval threshold is 2 s, if the body fat scale obtains that the user performs one foot movement and there are no other foot movements within 2 s, it determines that this foot movement is a single-click movement, and the single-click movement can be applied to the user switching pages on the user display screen of the body fat scale, making it easy for the user to view corresponding graphs of his / her body fat, body weight and muscle weight, or detection result diagrams of body fat, body weight and muscle weight, etc.

[0060] If the body fat scale obtains that the user performs two foot movements and the interval time between two adjacent foot movements is 1 second, it determines that this foot movement is a double click movement, which can be applied to the user checking options or physical data on the user display screen of the body fat scale. Since the operation time required for switching or checking is short, it can not only be distinguished from other operations, but also improve the efficiency of controlling the user display screen.

[0061] If the body fat scale detects that the user performs three foot movements and that the interval time between two adjacent foot movements among the three foot movements is 3 seconds, it determines that the detected foot movement is a triple-click movement, which is applicable to quick user switching, and enables the user to quickly switch pages on the display screen and reduces erroneous touching.

[0062] Based on the fact that different numbers of foot movements of the user correspond to different movement types, different control operations are performed on the user display screen, and the movement type can be identified based on only the number of foot movements, thereby reducing the difficulty of identifying the movement type and improving the accuracy and efficiency of controlling the user display screen.

[0063] In one embodiment of the present application, the body fat scale obtains the duration of the continuous strong step of the foot action, and determines whether the user's foot action is a long press action or a short press action based on the duration of the continuous strong step.

[0064] If the continuous stepping time is equal to or longer than the predetermined stepping time, the user's foot action is determined to be a long press action, and if the continuous stepping time is shorter than the predetermined stepping time, the user's foot action is determined to be a short press action. The length of the predetermined stepping time may be set before shipment or may be set by the user according to his / her needs, and is not limited here.

[0065] "Continuous strong stepping" means that the user's foot steps on the body fat scale without loosening and continuously applies pressure to the body fat scale. Continuous strong stepping allows the user's foot to be identified as a foot movement even when it is simply resting on the body fat scale, and prevents multiple stepping movements from being mistakenly identified as a single foot movement, thereby improving the accuracy of identifying foot movements.

[0066] For example, if the specified stepping time is 3 seconds, and the continuous strong stepping time of the user's foot motion acquired by the body fat scale is 4 seconds, the current foot motion is determined to be a long press motion, and a long press motion can be used when the user turns off the body fat scale. Because an off operation usually needs to last for several seconds, the long press motion filters out erroneous operations. For example, if the continuous strong stepping time of the user's foot motion acquired by the body fat scale is 2 seconds, the current foot motion is determined to be a short press motion, and a short press motion can be used when the user switches pages or selects an option on the user display screen of the body fat scale. Because the operation time required for switching or selecting an option is short, the short press motion not only can be distinguished from an off operation, etc., but also improves the efficiency of controlling the user display screen.

[0067] In one embodiment of the present application, the body fat scale determines that the vibration area in which the foot movement occurs is the movement area, and determines whether the user's foot movement is a left foot movement and / or a right foot movement based on the movement area.

[0068] For example, if the body fat scale detects that the motion area where the foot motion occurs is the left surface of the body fat scale and that the vibration area changes from right to left, it determines that the user's foot motion is a left foot motion, and the left foot motion can be applied to the user switching a page or option on the user display screen of the body fat scale to a previous operation screen; if the body fat scale detects that the motion area where the foot motion occurs is the right surface of the body fat scale and that the vibration area changes from left to right, it determines that the user's foot motion is a right foot motion, and the right foot motion can be applied to the user switching a page or option on the user display screen of the body fat scale to a next operation screen.

[0069] The control effects corresponding to the foot movements in the above embodiment are merely exemplary, and the correspondence between the foot movements and the control effects is not unique, and may be adjusted and exchanged at the time of shipment and when the user uses the device. In other embodiments, the user's movement type may be realized by other interactive actions, either of which may be realized by the user's foot movements on the surface of the body fat scale, or may be realized by a combination of the foot movements and other information.

[0070] In step 12, the user display screen of the body fat scale is controlled based on the foot movement.

[0071] Specifically, after determining the motion type of the user's foot motion, the body fat scale further controls a user display screen of the body fat scale to perform a corresponding operation based on the motion type of the foot motion, the operation including at least one of an operation of determining a current page on the user display screen, an operation of switching options of the current page on the user display screen, and an operation of switching pages of the user display screen.

[0072] For the correspondence between the action types and the operations on the user operation screen, please refer to the above description.

[0073] Specifically, the display contents of the user display screen include at least one of a detection result diagram of body fat, body weight, and muscle weight, a correspondence graph of body fat, body weight, and muscle weight, a curve comparison diagram of any two or more of body fat, body weight, and muscle weight, and basic user information.

[0074] Referring to Fig. 4, Fig. 4 is a screen schematic diagram of a first embodiment of a user display screen of a body fat scale according to the present application. The user display screen includes basic information of users, i.e., user accounts, and each account includes the avatar and user name of each user, etc. When a user performs a foot movement in a set foot movement area of ​​the body fat scale to improve the identification accuracy of the foot movement, the body fat scale can obtain the movement type of the user's foot movement, realize a switching operation or a determination operation of an option of a current page on the display page, and complete the switching or selection for the user account.

[0075] Preferably, when a user uses the body fat scale, the user display screen of the body fat scale displays a message asking whether the user is using the scale for the first time, and the user can select "Yes" or "No" on the user display screen by moving his / her foot to realize a confirmation operation of the current page on the user display screen. If the user is using the scale for the first time, i.e., if the user selects "Yes", the user display screen provides an initial registration screen for user registration. In the initial registration, referring to Fig. 5, Fig. 5 is a screen schematic diagram of a second embodiment of the user display screen of the body fat scale according to the present application, and the body fat scale can realize personalized setting of user information by providing different avatars for user selection.

[0076] In another embodiment of the present application, reference is made to Fig. 6, which is a schematic diagram of a third embodiment of a user display screen of the body fat scale of the present application. After a user selects his / her user account on the user display screen, the display content of which is user basic information as shown in Fig. 4, the body fat scale will display the user's current weight on the user display screen, and display it in large bold letters in the center of the display screen for the user to confirm.

[0077] In another embodiment of the present application, the content of the user display screen may include a graph corresponding to the user's physical data. Refer to FIG. 7, which is a screen schematic diagram of a fourth embodiment of the user display screen of the body fat scale of the present application. The curve comparison chart may include three change curves of the user's weight, body fat, and muscle weight. By determining the change trend of the user's physical data based on the change in the curve comparison chart, the user can better understand the change of his / her physical data, and adjust his / her fitness regime, lifestyle, etc. accordingly.

[0078] Preferably, the curve comparison diagram may further include two change curves of the user's body fat and weight. The user can grasp the change relationship between his / her body fat and weight based on the changes in the curve comparison diagram, and thus not only pay attention to the weight but also pay attention to the change of the body fat, so that the user can properly adjust his / her body data in terms of diet, training, etc., and ensure that the user can achieve the goal of weight loss when he / she is healthy.

[0079] Preferably, the graph may further include a change curve of body fat, so that the user can intuitively feel the changes in physical constitution that he or she has achieved through fitness training or other methods based on the changes in the graph.

[0080] Preferably, the curve comparison chart may further include two change curves of the user's heart rate and body fat, which can help the user to understand the relationship between his / her heart condition and body fat in detail, and thus suggest to the user that the body fat percentage needs to be maintained at a normal level to ensure heart health.

[0081] Preferably, after the display of the curve comparison diagram on the user display screen is completed, the display screen may further include personalized recommendation content related to the user's lifestyle, which is generated based on the user's body data such as the user's weight, body fat, muscle weight, etc. For example, the display content on the user display screen may further include a recommendation for the user's daily energy intake value, a recommendation for the user's daily energy consumption required for training, a recommendation for the user's daily water intake value, daily recommended exercises, etc. The personalized recommendation content allows the user to more reasonably achieve goals such as weight loss and muscle gain based on his or her own body data.

[0082] Unlike the existing technology, the control method according to the present application is applied to a body fat scale, and the body fat scale identifies the user's foot motion in a wake-up state and controls the user display screen of the body fat scale based on the foot motion. In this manner, compared with the conventional body fat scale control method, the method of identifying the user's foot motion and controlling the body fat scale used in the present application controls the user display screen of the body fat scale according to the user's foot motion, thereby simplifying the user's operation of controlling the user display screen of the body fat scale, and thus the user does not need to download an APP or squat down to pick up the body fat scale, thereby simplifying the user's operation and improving the convenience of the user to control the user display screen of the body fat scale, thereby allowing the user to more easily interact with the body fat scale.

[0083] In one application scenario, when the body fat scale identifies that both feet of the user are standing on the body fat scale, it enters a wake-up state and then opens a user display screen. In the current page, the body fat scale obtains the user's vibration information for the body fat scale, and if it determines that the user's foot action is a single-click action, it controls to switch options in the current page, if it determines that the user's foot action is a double-click action, it controls to determine options or the user's physical data in the current display screen, if it determines that the user's foot action is a single-click action, it controls to switch the current page to another page, if it determines that the user's foot action is a long press action, it controls to turn off the body fat scale.

[0084] Naturally, in other application scenarios, a correspondence between the foot action type and the operation of the user display screen may be set according to the user's own operating habits, or other foot action types and operations may be added, without any specific limitations.

[0085] In another embodiment, the method shown in FIG. 8 is used to control the user display screen according to different control modes, and FIG. 8 is a flow chart of an embodiment in which the body fat meter according to the present application controls the display screen according to different control modes. The method of this embodiment includes steps 81 to 83.

[0086] In step 81, the wakeup state is entered and the control mode is acquired.

[0087] Specifically, the body fat scale enters the wake-up state in a manner in step 11, which will not be repeated here. The control modes are two modes that control how the body fat scale displays the user display screen, and the user may select them himself on the user display screen.

[0088] In step 82, if the control mode is a foot control mode, steps are performed to identify the user's foot motion in the wake-up state.

[0089] Specifically, if the current control mode of the body fat scale is the foot control mode, execute step 11 to identify the user's foot motion, control the user display screen of the body fat scale based on the user's foot motion, and execute subsequent steps.

[0090] In step 83, if the control mode is the automatic control mode, the user display screen of the body fat scale is controlled based on a predetermined time interval.

[0091] Specifically, when the current control mode of the body fat scale is the automatic control mode, the user display screen of the body fat scale is switched within a predetermined time interval; for example, when the predetermined time interval is 3 s, the current user display screen of the body fat scale is automatically switched to the next user display screen within 3 s.

[0092] In one embodiment of the present application, if the body fat scale does not identify a foot motion within a predetermined time, it automatically switches pages and controls the display screen to execute an operation on the user display screen, for example. The length of the predetermined time may be set before shipment or may be set by the user according to the needs of the user, and is not limited here.

[0093] The methods of the above-mentioned embodiments may be implemented by a body fat scale, which will be described below with reference to FIG. 9, which is a schematic diagram of a first embodiment of a body fat scale according to the present application.

[0094] 9, a body fat scale 90 of this embodiment includes a case 91, a processor 92, and a motion detection sensor 93. A display for displaying a user display screen or a projection device for projecting and displaying the user display screen is installed in the case 91, and the processor 92 is installed within the case 91, identifies the user's foot motion in a wake-up state, and controls the user display screen displayed on the body fat scale based on the foot motion.

[0095] Compared with conventional body fat scales, the body fat scale 90 of this embodiment controls the body fat scale 90 by identifying the user's foot movements, and controls the user display screen of the body fat scale 90 according to the user's foot movements, thereby simplifying the user's operation of controlling the user display screen of the body fat scale 90. Therefore, by realizing control of the user display screen of the body fat scale 90 without the user having to download an APP, the user operation can be simplified and the user can more easily interact with the body fat scale 90.

[0096] Furthermore, in this embodiment, by identifying the user's foot motion in the wake-up state, it is possible to prevent the user from performing unnecessary foot operations.

[0097] A display or the like may be provided in the body fat scale 90, and the user display screen may be displayed by the display. Alternatively, a projection device may be provided in the body fat scale 90, and after the body fat scale 90 enters the wake-up mode, the projection device is controlled to project the user display screen onto a projection receiving area, such as the ground or a wall surface. The display may protrude from the surface of the body fat scale.

[0098] Preferably, the body fat scale 90 of this embodiment further includes a motion detection sensor 93 that is installed in the case and connected to the processor 92 to acquire motion information of the user on the body fat scale, and the processor 92 determines the user's foot motion based on the motion information.

[0099] Compared to conventional body fat scales, a motion detection sensor is installed on the surface of body fat scale 90 of this embodiment, and motion detection sensor 93 acquires information about the user's motion on the body fat scale. Processor 92 determines the user's foot motion based on the motion information, and when the user performs a foot motion on the body fat scale, the user steps on the body fat scale, causing the body fat scale to vibrate. In this embodiment, the body fat scale can accurately acquire information about the user's motion on the body fat scale through the vibration sensor, improving the accuracy of interaction.

[0100] In one embodiment of the present application, the motion detection sensor 93 includes a vibration sensor, the motion information includes vibration information, and the vibration sensor obtains vibration information of the case.

[0101] A vibration sensor is a device or element that measures the vibration of an object, and determines the vibration state of the object by detecting minute displacements or speed changes caused by vibrations on the surface of the object. When a user performs foot movements on the body fat scale, the user steps on the body fat scale, causing the body fat scale to vibrate. In this embodiment, the body fat scale can accurately obtain information on the user's movements on the body fat scale using the vibration sensor.

[0102] Preferably, the vibration sensor includes one or more of an acceleration sensor, a velocity sensor, a displacement sensor, and a force sensor.

[0103] An acceleration sensor is a sensor that detects vibration conditions by measuring the acceleration of an object. Acceleration sensors are usually manufactured with MEMS and their operating principle is based on Newton's second law. When an object vibrates, the acceleration sensor measures the acceleration of the object to calculate the vibration characteristic parameters of the object, i.e., vibration information.

[0104] An acceleration sensor is a sensor that measures the moving speed of an object, and can detect and measure the moving speed of an object and convert it into an electrical signal. A speed sensor generates electromagnetic induction using an electromagnetic coil, and this electromagnetic induction changes when an object vibrates, and measures the vibration information of the object based on the changed electromagnetic induction.

[0105] Displacement sensors, also called linear sensors, are linear devices that belong to the metal induction class and their role is to convert various physical quantities to be measured into electrical quantities. For example, potentiometer-type displacement sensors use a potentiometer element to convert the mechanical displacement of an object (for example, the vibration displacement of the surface of a body fat scale) into impedance or voltage that has a linear or arbitrary functional relationship with the mechanical displacement of the object, and output it to measure vibration information of the object.

[0106] In the force sensor, four strain gauges form a Wheatstone bridge, and the strain gauges are firmly attached to the elastic body, so that the strain gauges deform in the same way as the elastic body, and the impedance changes due to the customized small volume force sensor, and the output signal of the Wheatstone bridge provides these deformation information, thus the magnitude of the force acting on the strain gauge can be calculated and the vibration information of the object can be measured.

[0107] The vibration sensor may be a piezoelectric vibration sensor, which can realize vibration detection and measurement by converting mechanical vibration of an object into an electrical signal.

[0108] In one embodiment of the present application, a foot movement area and a display area are provided on the body fat scale 90, the user display screen is displayed in the display area, and the foot movement detection sensor 93 is provided in the foot movement area, so that the foot movement area and the display area do not overlap.

[0109] By setting up the foot operation area and the display area separately, visual interference by the feet with the user display screen is reduced, thereby not only improving the accuracy of controlling the user display screen, but also preventing situations where the user is unable to see the data information on the user display screen clearly due to the feet blocking the view.

[0110] Preferably, the foot motion area includes an optimal foot area, the distance between the left side of the optimal foot area and the left side of the case 91 and the distance between the right side of the optimal foot area and the right side of the case 91 are greater than a distance threshold, and the distance difference between the distance between the left side of the optimal foot area and the right side of the optimal foot area and the distance between both feet when the user is standing naturally is less than the distance threshold, and the area sensitivity of the optimal foot area is greater than the area sensitivity of other areas of the foot motion area.

[0111] The area sensitivity refers to a vibration change threshold value at which a region receives vibration information and is identified as a foot motion. Since the optimal foot region of the foot motion region has the highest area sensitivity, the foot motion acquired by the body fat scale when the user is naturally standing on the body fat scale is the most accurate foot motion, and the foot motion performed by the user in the optimal foot region can be accurately and quickly identified by the body fat scale. The motion detection sensor 93 may be installed corresponding to the optimal foot region.

[0112] The display area and the foot action area are both on the side of the case 91 facing the user, and the two areas may be flush or have a certain elevation difference.

[0113] In another embodiment, as shown in Figs. 10 to 12, Fig. 10 is a schematic perspective configuration diagram of a second embodiment of a body fat scale according to the present application. Fig. 11 is a schematic plan view of the embodiment of Fig. 10. Fig. 12 is a schematic bottom view of the embodiment of Fig. 10. Display 111 is installed in the center front of case 91, and other positions may be set as foot operating areas, and a bracket, a battery box, etc. may be installed on the downward side of case 91.

[0114] The above description is merely an embodiment of the present application and does not limit the scope of protection of the present application. Any equivalent structure or equivalent flow conversion made by using the contents of the specification and drawings of the present application, or direct or indirect applications in other related technical fields, are also included in the scope of protection of the present application.
