[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B, and C.

[0044] The control method provided in this application is mainly used for body fat scales and other related weighing equipment. The body fat scale recognizes the user's foot movements and enables the user to control the user display interface of the body fat scale based on the foot movements.

[0045] At present, the main way for users to control body fat scales includes that users go to the corresponding official website according to the type of body fat scale and download the corresponding APP to the mobile phone. The body fat scale can be controlled through the APP. The various measured data can only be viewed independently through the APP, or only simple operations such as turning on and off the body fat scale can be performed according to the buttons on the body fat scale. Some more targeted control operations cannot be achieved. Therefore, when using the existing control method to control the user display interface of the body fat scale, the user cannot directly operate the user display interface of the body fat scale through the body, but needs to download the APP and operate it through the mobile phone when using it. This will increase the complexity of the interaction process, greatly increase the threshold for using the body fat scale, and have a great impact on the user experience. Based on this, the present application provides a method for controlling the user display interface of a body fat scale. The technical solution adopted in the present application is described in detail below.

[0046] See also Figure 1 , Figure 1 It is a flow chart of an embodiment of a method for controlling a user display interface of a body fat scale provided in the present application.

[0047] Step 11: Identify the user's foot movements in the awake state.

[0048] Specifically, the body fat scale enters the awake state by determining whether the user's feet are standing on the body fat scale. For example, after the body fat scale is powered on, it determines whether the user's feet are standing on the body fat scale. If the user's feet are standing on the body fat scale, the body fat scale enters the awake state; in the awake state, the user can control the user display interface of the body fat scale through his or her foot movements. This embodiment can avoid some misoperations or detections caused by objects falling on the body fat scale by identifying the user's foot movements in the awake state.

[0049] Among them, the awakening state means that the body fat scale is currently in a waiting working state, the processor of the body fat scale is running, and can perform corresponding operations after receiving instructions.

[0050] Optionally, after the body fat scale obtains the weight change on the body fat scale, it sends a safe current through the object to measure the resistance of the object. If the resistance is within the preset resistance range, it is confirmed that a human is standing on the body fat scale. This further avoids the situation where an object with a similar weight to a human falls on the body fat scale and causes a false detection. Among them, the preset resistance range can be set according to the average resistance range of the human body before the body fat scale leaves the factory.

[0051] In one embodiment of the present application, the body fat scale obtains the weight change of the user; in response to the weight change being within a preset range, it is determined that the user's feet are standing on the body fat scale. The size of the preset range can be set before leaving the factory, or it can be set according to user needs, such as the user's actual weight, which is not limited here. This embodiment determines whether the user's feet are standing on the body fat scale by the user's weight change, thereby entering the wake-up state, which can avoid accidental touch interference caused by the user touching the body fat scale with one foot or other objects placed on the body fat scale, and can improve the control accuracy of the body fat scale entering the wake-up state.

[0052] After entering the wake-up mode, the body fat scale will open the user display interface and recognize the user's foot movements when the user display interface is in the display state. In this way, the body fat scale first opens the user display interface, initializes the user display interface, and then recognizes the user's foot movements, which makes it easier for the user to control the user display interface based on the content of the user display interface. This can not only improve the user experience, especially for novice users of body fat scales, but also improve the accuracy of controlling the user display interface.

[0053] Optionally, the body fat scale is provided with a display screen, etc., and the user display interface can be displayed on the display screen. Alternatively, a projection device can be provided on the body fat scale, and after the body fat scale enters the wake-up mode, the body fat scale controls the projection device to project the user display interface onto a projection bearing area, such as the ground, a wall, etc.

[0054] Optionally, the body fat scale is provided with a motion detection sensor, and this embodiment can be performed as follows Figure 2The method shown implements step 11, and the method of this embodiment includes step 21 and step 22.

[0055] Step 21: Obtain the user's motion information on the body fat scale through the motion detection sensor.

[0056] Specifically, the motion detection sensor includes a vibration sensor, the motion information includes vibration information, and obtaining the motion information of the user on the body fat scale through the motion detection sensor includes: obtaining vibration information through the vibration sensor.

[0057] 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 the tiny displacement or velocity change caused by the vibration of the object surface. Vibration sensors include acceleration sensors, piezoelectric sensors, laser interferometers, etc. When a user moves his feet on a body fat scale, he steps on the body fat scale, causing the body fat scale to vibrate. The body fat scale of this embodiment can accurately obtain the user's action information on the body fat scale through the vibration sensor.

[0058] In one embodiment of the present application, the vibration sensor may be an acceleration sensor, and the body fat scale obtains the vibration information of the body fat scale through the acceleration sensor. An acceleration sensor is a sensor that detects vibration by measuring the acceleration of an object. Acceleration sensors are usually made of micro-electromechanical systems (MEMS), and their working principle is based on Newton's second law. When an object vibrates, the acceleration sensor measures the acceleration of the object, thereby calculating the vibration characteristic parameters of the object, that is, the vibration information.

[0059] 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 working principle is based on the piezoelectric effect. The piezoelectric effect refers to the phenomenon that certain crystal materials, when subjected to mechanical stress, produce an uneven charge distribution, thereby generating an electric potential difference. By using 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 made of piezoelectric ceramic materials, and its structure includes a vibration sensitive element, a signal amplifier, a filter, a microprocessor, and an output interface. When an object vibrates, the vibration sensitive element will produce a tiny uneven charge distribution, thereby generating a weak electrical signal. The signal amplifier will amplify this weak electrical signal, the filter will filter out clutter and interference signals, and the microprocessor will digitally process and analyze the signal to extract useful vibration characteristic parameters. Finally, the output interface will output an analog voltage signal or a digital signal for connecting a data acquisition system or a control system. Piezoelectric vibration sensors have the advantages of high sensitivity, high precision, and low power consumption, and are suitable for measuring tiny vibration signals. They are widely used in the fields of vibration monitoring and fault diagnosis of mechanical equipment, vibration monitoring and safety assessment of structures, acoustic vibration monitoring and non-contact measurement.

[0060] Step 22: Identify the user's foot movements based on the movement information.

[0061] The body fat scale recognizes the user's foot movements based on the vibration information. Specifically, the vibration information includes the vibration change amount. This embodiment can be Figure 3 The method shown implements step 22 , and the method of this embodiment includes steps 31 and 32 .

[0062] Step 31: When the vibration variation is greater than or equal to the vibration sensitivity, it is determined that the user has made a foot movement.

[0063] When the body fat scale obtains that the vibration change is greater than or equal to the vibration sensitivity, it is determined that the user has made a foot movement.

[0064] Specifically, vibration sensitivity is a threshold value used by the body fat scale to determine whether the acquired vibration change is a vibration change generated by the user. The vibration sensitivity can be obtained by user input or import or extracted from the database of the body fat scale. Exemplarily, the vibration sensitivity can be pre-stored in the database of the body fat scale, and the body fat scale can obtain the vibration sensitivity by calling the database. Of course, the vibration sensitivity can also be imported by the user, and the user can collect the vibration sensitivity in advance and then import it into the body fat scale. Therefore, there are many ways to obtain the vibration sensitivity, which are not specifically limited here.

[0065] Step 32: Determine the motion type of the foot movement.

[0066] The body fat scale further determines the action type based on the recognized foot action of the user to determine the specific operation of the user on the user display interface, so as to facilitate the body fat scale to control the switching of its user display interface, etc. The body fat scale can pre-store or allow the user to set the mapping relationship between the action type and the specific operation on the user display interface. Different users can set the mapping relationship based on their own operating habits, which can realize personalized control of the user display interface and improve user experience. Moreover, since the user sets the mapping relationship based on his own operating habits, the efficiency of the user's control over the user interface can be improved.

[0067] In one embodiment of the present application, the body fat scale determines the number of footsteps, which is the number of foot movements detected within a preset time period; based on the number of footsteps, the user's foot movement is determined to be a single click or a continuous click. The preset time period can be set before leaving the factory or can be set according to user needs, which is not limited here.

[0068] The body fat scale continuously detects vibration information and determines the number of foot movements based on the vibration change. The minimum value of the vibration change during a single foot movement is greater than or equal to the threshold, where the difference between the sensitivity and the threshold is the vibration fluctuation value of the body fat scale during a single foot movement.

[0069] For example, when the preset time length is 2s, if the body fat scale detects that the user has made multiple (multiple includes two or more) foot movements within 2s, the user's current foot movement is considered to be a continuous action; if the body fat scale detects that the user has made one foot movement within 2s, the user's current foot movement is considered to be a single click action.

[0070] In one embodiment of the present application, the body fat scale determines that the foot movement is a combo movement in response to the interval between two consecutive foot movements generated by the user being less than or equal to the interval threshold. The size of the interval threshold can be set before leaving the factory or can be set according to user needs, which is not limited here.

[0071] For example, when the interval threshold is 2s, if the body fat scale detects that the user has made a foot movement and there is no other foot movement within 2s, then this foot movement is considered to be a single click action. The single click action can be used to switch pages in the user display interface of the body fat scale, making it convenient for users to view the corresponding curve graphs of their body fat, weight, and muscle weight, or the detection result graphs of body fat, weight, and muscle weight, etc.

[0072] If the body fat scale detects that the user has made two foot movements, and the interval between the two adjacent foot movements is 1s, then this foot movement is considered to be a double-click action. The double-click action can be used for the user to confirm the options or body data in the user display interface of the body fat scale; because the operation time required for switching or confirmation is shorter, it can not only be distinguished from other operations, but also improve the efficiency of controlling the user display interface.

[0073] If the body fat scale detects that the user has made three foot movements, and the interval between two adjacent foot movements in the three foot movements is 3s, then the obtained foot movement is considered to be a triple-click action. The triple-click action can be used for quick switching of users. By using the triple-click action, quick switching of pages in the user display interface can be achieved, which can reduce accidental touches.

[0074] Different action types are mapped according to the different numbers of foot movements by the user, so as to perform different control operations on the user display interface. The action type can be identified only by the number of foot movements, which can reduce the difficulty of action type identification and improve the accuracy and efficiency of controlling the user display interface.

[0075] In one embodiment of the present application, the body fat scale obtains the continuous heavy stepping duration 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 continuous heavy stepping duration.

[0076] When the continuous stepping time is greater than or equal to the preset stepping time, the user's foot action is considered to be a long press action, and when the continuous stepping time is less than the preset stepping time, the user's foot action is considered to be a short press action. The preset stepping time can be set before leaving the factory or can be set according to user needs, and is not limited here.

[0077] Among them, continuous heavy stepping means that the user's feet are stepped on the body fat scale without loosening, and continue to apply pressure to the body fat scale, so as to avoid identifying the user's mere placement of the feet on the body fat scale as a foot movement, thereby mistakenly identifying multiple stepping movements as a single foot movement. Therefore, the accuracy of foot movement recognition can be improved.

[0078] For example, when the preset foot-stepping duration is 3s, and when the body fat scale obtains the user's foot action of continuous heavy stepping duration of 4s, it is considered that this foot action is a long press action, and the long press action can be applied to the user's shutdown operation of the body fat scale, because the shutdown operation usually needs to last for several seconds to filter out misoperation; when the body fat scale obtains the user's foot action of continuous heavy stepping duration of 2s, it is considered that this foot action is a short press action, and the short press action can be applied to the user's switching of pages or selection of options in the user display interface of the body fat scale, because the operation time required for switching or selecting options is shorter, it can not only distinguish it from the shutdown operation, but also improve the efficiency of controlling the user display interface.

[0079] In one embodiment of the present application, the body fat scale obtains the vibration area that produces the foot movement as the action area; based on the action area, it is determined that the user's foot movement is a left foot movement and / or a right foot movement.

[0080] For example, when the body fat scale obtains that the action area generating the foot movement is the left side of the action area of ​​the body fat scale, and the vibration area changes from right to left, it is determined that the user's foot movement is a left foot movement, and the left foot movement can be used for the user to switch the page or option in the user display interface of the body fat scale to the previous operation interface; when the body fat scale obtains that the action area generating the foot movement is the right side of the action area of ​​the body fat scale, and the vibration area changes from left to right, it is determined that the user's foot movement is a right foot movement, and the right foot movement can be used for the user to switch the page or option in the user display interface of the body fat scale to the next operation interface.

[0081] The control effects corresponding to the foot movements in the above embodiments are only examples. The correspondence between foot movements and control effects is not unique and can be adjusted and replaced at the factory or when used by the user. In other embodiments, the user's action type can also be realized by other interactive actions and can be reflected by the user's foot movements on the scale surface of the body fat scale, or by a combination of foot movements and other information.

[0082] Step 12: Control the user display interface of the body fat scale based on the foot movement.

[0083] Specifically, after the body fat scale determines the action type of the user's foot action, it will also control the user display interface of the body fat scale to perform a corresponding operation based on the action type of the foot action. The operation includes: at least one of: determining the current page in the user display interface, switching the options of the current page in the user display interface, and switching the pages of the user display interface.

[0084] For the correspondence between action types and operations on the user interface, please refer to the above introduction.

[0085] Specifically, the display content of the user display interface includes at least one of the following: a test result graph of body fat, weight, and muscle weight; a corresponding curve graph of body fat, weight, and muscle weight; a curve comparison graph of any two or more of body fat, weight, and muscle weight; and basic user information.

[0086] See also Figure 4 , Figure 4This is an interface diagram of the first embodiment of the user display interface of the body fat scale provided by the present application. The user display interface includes basic information of the user, namely the user account, and each account includes a respective user avatar and user name, etc. The user can perform foot movements in the foot movement area set by the body fat scale to improve the accuracy of foot movement recognition, so that the body fat scale can obtain the action type of the user's foot movement, so as to implement the switching operation or confirmation operation of the options of the current page in the display page, and complete the switching or selection of the user account.

[0087] Optionally, when a user uses a body fat scale, the user interface of the body fat scale will display a prompt message to indicate whether the user is using it for the first time. The user can select yes or no by moving his feet on the user interface to confirm the current page in the user interface. If the user is using it for the first time, that is, selects yes, the user interface will provide an initial registration interface for the user to register. Figure 5 , Figure 5 This is an interface diagram of the second embodiment of the user display interface of the body fat scale provided in the present application. The body fat scale can provide different avatars for users to choose from, thereby realizing personalized setting of user information.

[0088] In another embodiment of the present application, see Figure 6 , Figure 6 is a schematic diagram of the third embodiment of the user display interface of the body fat scale provided by the present application. Figure 4 The displayed content shown is the user display interface of the user's basic information. After selecting your own user account, the body fat scale displays the user's current weight in bold and uppercase in the middle of the display interface for the user to confirm.

[0089] In another embodiment of the present application, the content of the user display interface may include a curve chart corresponding to the user's physical data, see Figure 7 , Figure 7 This is a schematic diagram of the fourth embodiment of the user display interface of the body fat scale provided by the present application. The curve comparison chart may include three change curves of the user's weight, body fat, and muscle weight. Through the changes in the curve comparison chart, the change trend of the user's body data can be determined, so that the user can better understand the changes in his or her body data and adjust his or her fitness methods, living habits, etc. accordingly.

[0090] Optionally, the curve comparison chart may also include two curves of changes in the user's body fat and weight. Through the changes in the curve comparison chart, the user can know the changing relationship between his body fat and his weight, so that the user can pay attention not only to his weight but also to the changes in body fat, so as to adjust his body data in terms of diet, exercise, etc., so as to ensure that the user can achieve the goal of weight loss while being healthy.

[0091] Optionally, the curve graph may also include a change curve of body fat, so that the user can intuitively feel the changes in his or her physical fitness achieved through fitness exercises and other methods through the changes in the curve graph.

[0092] Optionally, the curve comparison chart may also include two change curves of the user's heart rate and body fat, to help the user understand in detail the relationship between his or her heart condition and body fat, thereby reminding the user to maintain a normal body fat percentage in order to ensure heart health.

[0093] Optionally, after the user display interface displays the curve comparison chart, it can also include personalized recommendations on the user's lifestyle based on the user's body data such as weight, body fat, muscle weight, etc. For example, the display content of the user display interface can also include the recommended daily energy intake value for the user, the energy consumed by the user's daily exercise, the recommended daily water intake value for the user, and daily recommended exercise, etc. Personalized recommendations can help users achieve the goals of weight loss, muscle gain, etc. more reasonably based on their own body data.

[0094] Different from the prior art, the control method provided by the present application is applied to a body fat scale, which recognizes the user's foot movements in the awake state and controls the user display interface of the body fat scale based on the foot movements. In the above manner, compared with the conventional control method of the body fat scale, the method of identifying the user's foot movements and controlling the body fat scale adopted by the present application can control the user display interface of the body fat scale through the user's foot movements, thereby simplifying the user's control operation on the user display interface of the body fat scale, so that the user can control the user display interface of the body fat scale without downloading an APP or squatting down to pick up the body fat scale, thereby simplifying the user operation and improving the convenience of the user's control of the user display interface of the body fat scale, thereby enabling the user to interact with the body fat scale more conveniently.

[0095] In one application scenario, the body fat scale recognizes that the user is standing on the body fat scale with both feet, enters the wake-up state, and then opens the user display interface. On the current page, the body fat scale obtains the vibration information of the user on the body fat scale, and when it is determined that the user's foot action is a single click, it controls the options in the current page to switch; if it is determined that the user's foot action is a double click, it controls the determination of the options or user's body data in the current display interface; if it is determined that the user's foot action is a single click, it controls the current page to switch to other pages; if it is determined that the user's foot action is a long press operation, it controls the body fat scale to shut down.

[0096] Of course, in other application scenarios, the correspondence between the foot movement type and the operation of the user display interface can be set according to the user's own operating habits, or other foot movement types and operations can be added, without specific limitation.

[0097] In another embodiment, using Figure 8 The method shown controls the user display interface according to different control modes. Figure 8 The method of this embodiment includes steps 81 to 83.

[0098] Step 81: Enter the awake state and obtain the control mode.

[0099] Specifically, the body fat scale enters the awakening state through the method in step 11, which will not be described in detail here. The control mode is two modes in which the body fat scale controls how the user display interface is displayed, and can be selected by the user in the user display interface.

[0100] Step 82: When the control mode is the foot control mode, the step of recognizing the user's foot movements in the awake state is executed.

[0101] Specifically, when the current control mode of the body fat scale is the foot control mode, step 11 is executed to identify the user's foot movements, and the user display interface of the body fat scale is controlled based on the user's foot movements, and subsequent steps are executed.

[0102] Step 83: When the control mode is the automatic control mode, the user display interface of the body fat scale is controlled based on a preset time interval.

[0103] Specifically, when the current control mode of the body fat scale is the automatic control mode, the user display interface of the body fat scale will switch within a preset time interval. For example, when the preset time interval is 3s, the current user display interface of the body fat scale will automatically switch to the next user display interface within 3s.

[0104] In one embodiment of the present application, if the body fat scale does not recognize the foot movement within the preset time, the display interface is controlled to automatically switch pages, for example, the above-mentioned operation on the user display interface is performed. The preset time can be set before leaving the factory or can be set according to user needs, which is not limited here.

[0105] The method of the above embodiment can be implemented using a body fat scale. Fig. 9 Describe, Fig. 9 It is a structural schematic diagram of an embodiment of a body fat scale provided in this application.

[0106] like Fig. 9 As shown, the body fat scale 90 of this embodiment includes a housing 91, a processor 92 and a motion detection sensor 93. The housing 91 is provided with a display screen or a projection device, the display screen is used to display the user display interface, and the projection device is used to project and display the user display interface; the processor 92 is arranged in the housing 91, and is used to identify the user's foot movements in the awakened state, and control the user display interface displayed on the body fat scale based on the foot movements.

[0107] Compared with conventional body fat scales, the body fat scale 90 of this embodiment recognizes the user's foot movements to control the body fat scale 90. The user display interface of the body fat scale 90 can be controlled by the user's foot movements, thereby simplifying the user's control operation on the user display interface of the body fat scale 90, so that the user can control the user display interface of the body fat scale 90 without downloading an APP, thereby simplifying user operations and allowing the user to interact with the body fat scale 90 more conveniently.

[0108] Furthermore, this embodiment can prevent the user from performing unnecessary foot operations by identifying the user's foot movements in the awake state.

[0109] The body fat scale 90 is provided with a display screen, etc., and the user display interface can be displayed on the display screen. Alternatively, a projection device can be provided on the body fat scale 90. After the body fat scale 90 enters the wake-up mode, the projection device is controlled to project the user display interface onto a projection bearing area, such as the ground, a wall, etc. Among them, the display screen can protrude from the scale surface.

[0110] Optionally, the body fat scale 90 of this embodiment also includes: a motion detection sensor 93, which is arranged in the shell and connected to the processor 92, and the motion detection sensor 93 is used to obtain the user's motion information on the body fat scale, and the processor 92 determines the user's foot movement based on the motion information.

[0111] Compared with conventional body fat scales, the body fat scale 90 of this embodiment is provided with a motion detection sensor on the scale surface. The motion detection sensor 93 is used to obtain the user's motion information on the body fat scale. The processor 92 determines the user's foot movements based on the motion information. When the user makes foot movements on the body fat scale, the body fat scale will be stepped on, causing the body fat scale to vibrate. The body fat scale of this embodiment can accurately obtain the user's motion information on the body fat scale through the vibration sensor, thereby improving the accuracy of the interaction.

[0112] 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 shell.

[0113] Among them, the vibration sensor is a device or element that measures the vibration of an object. It determines the vibration state of the object by detecting the tiny displacement or speed change caused by the vibration of the object surface. When the user moves his feet on the body fat scale, he steps on the body fat scale, causing the body fat scale to vibrate. The body fat scale of this embodiment can accurately obtain the user's action information on the body fat scale through the vibration sensor.

[0114] Optionally, the vibration sensor includes one or more of an acceleration sensor, a velocity sensor, a displacement sensor, and a force sensor.

[0115] Among them, an accelerometer is a sensor that detects vibration by measuring the acceleration of an object. Accelerometers are usually made of MEMS and their working principle is based on Newton's second law. When an object vibrates, the accelerometer measures the acceleration of the object and calculates the vibration characteristic parameters of the object, that is, the vibration information.

[0116] A speed sensor is a sensor that measures the speed of an object. It can detect and measure the speed of an object and convert it into an electrical signal. The speed sensor generates electromagnetic induction through an electromagnetic coil. This electromagnetic induction changes when the object vibrates, and the vibration information of the object is measured based on the changing electromagnetic induction.

[0117] Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electrical quantities. For example, the potentiometer displacement sensor converts the mechanical displacement of an object (such as the vibration displacement of the scale surface) into a resistance or voltage output that is linear or has an arbitrary function relationship with it through the potentiometer element, thereby measuring the vibration information of the object.

[0118] The force sensor is composed of four strain gauges forming a Wheatstone bridge. Since the strain gauge is firmly adhered to the elastomer, the strain gauge will produce the same deformation as the elastomer, which causes the resistance to change. The Wheatstone bridge output signal will provide this deformation information, so that the force acting on the strain gauge can be calculated, thereby measuring the vibration information of the object.

[0119] The vibration sensor can also be a piezoelectric vibration sensor, which can convert the mechanical vibration of an object into an electrical signal, thereby realizing vibration detection and measurement.

[0120] In one embodiment of the present application, the body fat scale 90 is provided with a foot motion area and a display area, the user display interface is displayed in the display area, and the foot motion detection sensor 93 is arranged in the foot motion area, wherein the foot motion area and the display area do not overlap.

[0121] By setting the foot action area and the display area differently, not only can the visual interference of the feet on the user display interface be reduced, thereby improving the accuracy of control of the user display interface, but it can also prevent the situation where the feet block the user from seeing the data information on the user display interface clearly.

[0122] Optionally, the foot motion area includes an optimal foot area, and the distance between the left side of the optimal foot area and the left side of the shell 91 and the distance between the right side of the optimal foot area and the right side of the shell 91 are greater than a distance threshold; and the 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 the feet of the user when standing naturally is less than a distance threshold; wherein, the regional sensitivity of the optimal foot area is greater than the other regional sensitivities of the foot motion area.

[0123] Among them, the regional sensitivity refers to the threshold value of the vibration change amount after the region receives the vibration information and is recognized as the foot movement. The regional sensitivity of the best foot area of ​​the foot movement area is the highest, so that when the user stands naturally on the body fat scale, the foot movement obtained by the body fat scale is the most accurate foot movement, and the foot movement of the user in the best foot area can be accurately and quickly recognized by the body fat scale. The motion detection sensor 93 can be set corresponding to the best foot area.

[0124] The display area and the foot action area are both on the side of the shell 91 facing the user, and the two areas can be coplanar or have a certain height difference.

[0125] In another embodiment, if Figures 10 to 12 As shown, Fig.10 It is a schematic diagram of the three-dimensional structure of the second embodiment of the body fat scale provided by the present application; Fig.11 yes Fig.10 A schematic top view of an embodiment; Fig.12 yes Fig.10 A bottom view of the embodiment. The display screen 111 is arranged in the middle front of the housing 91, and other positions can be set as foot movement areas. A bracket and a battery box can be arranged on the downward side of the housing 91.

[0126] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
