Description

Technical Field

[0001] This application relates to the technical field of measuring instruments, and particularly to a method for controlling the user display screen of a body fat scale and a body fat scale.

Background Art

[0002] With the development of the times, when the era of health consumption has come, people's requirements for a weighing scale are not limited to just measuring weight. As people's understanding of health knowledge becomes deeper and deeper, the body fat percentage has become an important indicator for people seeking health to grasp their own health level. Therefore, people's demand for body fat scales is also increasing.

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

[0004] In the prior art, when using a body fat scale, a user needs to carry a mobile phone and check user information or view measurement data through the mobile phone's APP, which is not convenient.

[0030] The technical means in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application, and it is clear that the embodiments described are only a part of the embodiments of the present application, not all of them. All other embodiments that can be obtained by a person skilled in the art without creative effort based on the embodiments of the present application are all within the scope of protection of the present application.

[0031] In this specification, the term "and / or" merely describes the relationship between related objects and indicates that there may be three types of relationships. For example, A and / or B can represent three situations: A existing alone, A and B existing together, and B existing alone. Also in this specification, the letter " / " generally indicates that the preceding and succeeding related objects are in an "or" relationship. Also in this specification, the letter "plural" indicates two or more. Also in this specification, the term "at least one" represents any combination of at least two of any one or more of the plural. 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.

[0032] The control method described in this application is mainly applied to related weighing devices such as body fat scales, which identify the user's foot movements and enable user control of the body fat scale's user display screen based on those foot movements.

[0033] Currently, the method of controlling a body fat scale mainly involves the user downloading a corresponding app from the official website corresponding to the type of body fat scale to their mobile phone, and then controlling the body fat scale through the app. However, the user can only view various data measured by the app independently, or perform simple operations such as on / off based on buttons on the body fat scale, and is unable to achieve more appropriate control operations. Therefore, when controlling the user display screen of a body fat scale using conventional control methods, the user cannot directly operate the user display screen with their limbs, and must download an app and operate it via their mobile phone. This increases the complexity of the interaction process, significantly increases the difficulty of using the body fat scale, and greatly affects the user experience. Based on this, this application provides a method for controlling the user display screen of a body fat scale, and the technical means used in this application will be described in detail below.

[0034] Referring to Figure 1, Figure 1 is a flowchart of one embodiment of a control method for the user display screen of a body fat scale according to the present invention.

[0035] Step 11 identifies the user's foot movements while the system is awake.

[0036] Specifically, the body fat scale enters a wake-up state when it determines that both of the user's feet are standing on the scale. For example, after powering on the body fat scale and activating it, it is determined whether both of the user's feet are standing on the scale. If both of the user's feet are standing on the scale, the body fat scale enters a wake-up state, and in the wake-up state, the user may control the user display screen of the body fat scale based on their foot movements. In this embodiment, by identifying the user's foot movements in the wake-up state, detections that occur in the event of some kind of error or when an object falls onto the body fat scale can be avoided.

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

[0038] Preferably, after the body fat scale detects a change in weight, it applies a safety current to the object to measure its impedance. If the impedance is within a predetermined impedance range, it confirms that a person is standing on the body fat scale. This further avoids false detections caused by objects similar in weight to a person falling onto the body fat scale. The predetermined impedance range may be set based on the average impedance range of the human body before the body fat scale is shipped.

[0039] In one embodiment of the present invention, the body fat scale acquires the user's weight change and determines that both of the user's feet are standing on the body fat scale in response to the weight change being within a predetermined range. The size of the predetermined range may be set before shipment, or may be set by the user according to their needs, for example, their actual weight, and is not limited herein. In this embodiment, by determining whether both of the user's feet are standing on the body fat scale based on the user's weight change, the scale enters a wake-up state, thereby avoiding interference from false contact caused by the user touching the body fat scale with one foot or by other objects being placed on the body fat scale, and improving the control accuracy of the body fat scale entering a wake-up state.

[0040] After entering wake-up mode, the body fat scale opens the user display screen and identifies the user's foot movements while the user display screen is displayed. This method allows the body fat scale to first open the user display screen, initialize it, and then identify the user's foot movements. This makes it easier for the user to control the user display screen based on its content, improving the user experience, especially for first-time users, and also improving the accuracy of controlling the user display screen.

[0041] Preferably, the body fat scale may be equipped with a display or the like, which may display a user-facing screen. Alternatively, the body fat scale may be equipped with a projection device, and after entering wake-up mode, the body fat scale may control the projection device to project the user-facing screen onto a projection receiving area, such as the ground or a wall.

[0042] Preferably, a motion detection sensor is installed in the body fat scale, and in this embodiment, step 11 can be realized in the manner shown in Figure 2, and the method of this embodiment includes steps 21 and 22.

[0043] In step 21, the body fat scale acquires user movement information using a motion detection sensor.

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

[0045] Specifically, a vibration sensor is a device or element that measures the vibration of an object. Its principle is to determine the vibration state of an object by detecting minute displacements or changes in velocity caused by vibrations on the object's surface. Vibration sensors include acceleration sensors, piezoelectric sensors, laser interferometers, and the like. When a user performs foot movements on a body fat scale, they step on the scale, causing it to vibrate. In this embodiment, the vibration sensor allows the body fat scale to accurately acquire information about the user's movements on the scale.

[0046] In one embodiment of the present invention, the vibration sensor may be an acceleration sensor, and the body fat scale acquires vibration information from the body fat scale using the acceleration sensor. An acceleration sensor is a sensor that detects vibration conditions by measuring the acceleration of an object. Acceleration sensors are usually manufactured using microelectromechanical systems (MEMS), and their operating principle is based on Newton's second law. When an object vibrates, the acceleration sensor calculates the vibration characteristic parameters of the object, i.e., vibration information, by measuring the acceleration of the object.

[0047] In one embodiment of the present invention, the vibration sensor may be a piezoelectric sensor. A piezoelectric vibration sensor is a sensor that converts mechanical vibrations into electrical signals, and its operating principle is based on the piezoelectric effect. The piezoelectric effect refers to the phenomenon in which, when a certain crystalline material is subjected to mechanical stress, a non-uniformity in charge distribution occurs, resulting in a potential difference. By utilizing this effect, vibration detection and measurement can be achieved by converting the mechanical vibrations of an object into electrical signals. Piezoelectric vibration sensors are usually manufactured from piezoelectric ceramic material, and their 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 minute non-uniformity in charge distribution, producing a weak electrical signal. The signal amplifier amplifies this 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 acquisition system or control system. Piezoelectric vibration sensors have advantages such as high sensitivity, high accuracy, and low power consumption, and are suitable for measuring minute vibration signals. Piezoelectric vibration sensors are widely used in fields such as vibration monitoring and fault diagnosis of machinery and equipment, vibration monitoring and safety assessment of structures, acoustic vibration monitoring, and non-contact measurement.

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

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

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

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

[0052] Specifically, vibration sensitivity is used by the body fat scale to determine whether the acquired vibration change amount is a vibration change threshold set by the user. The method for acquiring vibration sensitivity may be implemented by the user inputting or introducing it, or it may be extracted from the body fat scale's database. For example, vibration sensitivity may be stored in the body fat scale's database beforehand, and the body fat scale can acquire vibration sensitivity by calling the database. Of course, vibration sensitivity may also be introduced by the user, and the user may collect vibration sensitivity in advance and introduce it into the body fat scale. Therefore, there are many ways to acquire vibration sensitivity, and we will not limit ourselves to any particular method here.

[0053] Step 32 determines the type of foot movement.

[0054] The body fat scale further determines the type of motion based on the identified foot movements of the user, and by determining the specific user operations on the user display screen, it facilitates control such as switching the user display screen by the body fat scale. The body fat scale may pre-store or allow the user to set the mapping relationship between motion types and specific operations on the user display screen. Different users may set the mapping relationship based on their own operating habits, enabling personalized control of the user display screen and improving the user experience. Furthermore, because the user sets the mapping relationship based on their own operating habits, the efficiency of the user's control of the user display screen can be improved.

[0055] In one embodiment of the present invention, the body fat analyzer determines the number of foot movements that occur within a predetermined time, and determines whether the user's foot movement is a single-click or double-click movement based on the number of foot movements. The length of the predetermined time may be set before shipment or set by the user as needed, and is not limited thereto.

[0056] The body fat scale continuously detects vibration information and determines the number of foot movements based on the amount of vibration change. The minimum value of vibration change during a single foot movement is greater than or equal to a 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 by the user.

[0057] For example, if the predetermined time is 2 seconds, the body fat scale will determine that the user's current foot movement is a double-click if it detects that the user has performed multiple foot movements (including two or more times) within 2 seconds, and that the user's current foot movement is a single-click if it detects that the user has performed one foot movement within 2 seconds.

[0058] In one embodiment of the present invention, the body fat analyzer determines that a foot movement is a double-click movement in response to the interval between two adjacent foot movements performed by the user being less than or equal to an interval threshold. The magnitude of the interval threshold may be set before shipment or set by the user as needed, and is not limited herein.

[0059] For example, if the interval threshold is 2 seconds, the body fat scale will determine that the foot movement is a single click if it detects that the user has made one foot movement and that there have been no other foot movements within 2 seconds. A single click can be used to switch pages on the body fat scale's user display screen, making it easier for the user to view corresponding graphs of their body fat, weight, and muscle mass, or detection result diagrams of body fat, weight, and muscle mass.

[0060] The body fat scale determines that a foot movement is a double-click if it detects that the user performs two foot movements and that the interval between the two adjacent foot movements is 1 second. A double-click can be used to allow the user to view options or body data on the body fat scale's user display screen. Because the operation time required for switching or viewing is short, it can be distinguished from other operations and improve the efficiency of controlling the user display screen.

[0061] The body fat scale determines that a foot movement is a triple-click movement if it detects that the user performs three foot movements and that the interval between two adjacent foot movements is 3 seconds. Triple-click movements can be applied to rapid user switching, enabling quick page switching on the user-displayed screen and reducing accidental touches.

[0062] Based on the fact that different numbers of foot movements by the user correspond to different movement types, different control operations can be performed on the user display screen. By identifying the movement type solely based on the number of foot movements, the difficulty in identifying movement types can be reduced, and the accuracy and efficiency of controlling the user display screen can be improved.

[0063] In one embodiment of the present invention, the body fat meter obtains the duration of sustained strong pressing of the foot movement and determines whether the user's foot movement is a long press or a short press based on the duration of sustained strong pressing.

[0064] If the sustained pressing time is greater than or equal to a predetermined pressing time, the user's foot action is determined to be a long press action. If the sustained pressing time is less than the predetermined pressing time, the user's foot action is determined to be a short press action. The magnitude of the predetermined pressing time may be set before shipment, or it may be set by the user as needed, and is not limited herein.

[0065] "Continuous, firm pressing" means that the user's foot presses down on the body fat scale without releasing it and continuously applies pressure to the body fat scale. By continuously, firm pressing, even if the user's foot is just resting on the body fat scale, it is recognized as a foot movement, and the misidentification of multiple pressing movements as a single foot movement is avoided, thus improving the accuracy of foot movement recognition.

[0066] For example, if the predetermined stepping time is 3 seconds, and the sustained strong stepping time of the user's foot movement acquired by the body fat scale is 4 seconds, then the foot movement is determined to be a long press. A long press can be used to turn off the body fat scale, and since the off operation usually requires several seconds to be performed, the long press helps filter out erroneous operations. For example, if the sustained strong stepping time of the user's foot movement acquired by the body fat scale is 2 seconds, then the foot movement is determined to be a short press. A short press can be used to switch pages or select options on the user display screen of the body fat scale, and since the operation time required for switching or selecting options is short, a short press can not only be distinguished from operations such as turning off, but also improve the efficiency of controlling the user display screen.

[0067] In one embodiment of the present invention, the body fat analyzer acquires that the vibration region where foot movement occurs is an operating region, and determines whether the user's foot movement is a left foot movement and / or a right foot movement based on the operating region.

[0068] For example, if the body fat scale detects that the area of ​​motion where the foot movement occurred 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 movement is a left foot movement, and the left foot movement can be applied to the user switching the page or option on the body fat scale's user display screen to the previous operation screen. Similarly, if the body fat scale detects that the area of ​​motion where the foot movement occurred 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 movement is a right foot movement, and the right foot movement can be applied to the user switching the page or option on the body fat scale's user display screen to the next operation screen.

[0069] The control effects corresponding to foot movements in the above embodiments are merely illustrative, and the correspondence between foot movements and control effects is not unique; they may be adjusted and replaced at the time of shipment and during user use. In other embodiments, the user's action type may be realized by other interactive actions, and may be embodied by the user's foot movements on the surface of the body fat scale, or by a combination of foot movements and other information.

[0070] Step 12 controls the user display screen of the body fat scale based on foot movements.

[0071] Specifically, the body fat scale determines the type of foot movement of the user, and then controls the user display screen of the body fat scale to perform the corresponding operation based on the type of foot movement. The operation includes at least one of the following: determining the current page on the user display screen, switching the options on the current page on the user display screen, and switching the page on the user display screen.

[0072] For information on the correspondence between operation types and operations on the user interface, please refer to the explanation above.

[0073] Specifically, the content displayed on the user screen includes at least one of the following: a detection result diagram of body fat, body weight, and muscle weight; a correspondence graph of body fat, body weight, and muscle weight; a comparison diagram of any two or more curves of body fat, body weight, and muscle weight; and basic user information.

[0074] Referring to Figure 4, Figure 4 is a schematic diagram of the first embodiment of the user display screen of the body fat scale according to the present invention. The user display screen includes the user's basic information, i.e., the user account, and each account includes the user's avatar and username, etc. By having the user perform foot movements within the set foot movement area of ​​the body fat scale and improving the accuracy of foot movement identification, the body fat scale can acquire the type of movement of the user's foot movement, perform switching or confirmation operations of the options on the current page of the display page, and complete switching or selection of 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 it for the first time, and the user can select "yes" or "no" by foot movement on the user display screen to confirm the current page on the user display screen. If the user is using it for the first time, i.e., if "yes" is selected, the user display screen provides an initialization registration screen for user registration. Referring to Figure 5, which is a schematic diagram of a second embodiment of the user display screen of the body fat scale according to the present application, the body fat scale can enable personalized setting of user information by providing different avatars for user selection.

[0076] In another embodiment of the present invention, referring to Figure 6, Figure 6 is a schematic diagram of a third embodiment of the user display screen of the body fat scale according to the present invention. After the user selects their user account on the user display screen, which contains basic user information as shown in Figure 4, the body fat scale displays the user's current weight on the user display screen, and displays it in large, bold letters in the center of the screen so that the user can easily see it.

[0077] In another embodiment of the present invention, the content of the user display screen may include graphs corresponding to the user's physical data. Referring to Figure 7, Figure 7 is a schematic diagram of the screen of a fourth embodiment of the user display screen of the body fat scale according to the present invention. The curve comparison diagram may include three change curves for the user's weight, body fat, and muscle weight. By determining the trend of change in the user's physical data based on the changes in the curve comparison diagram, the user can better understand the changes in their physical data and adjust their fitness methods, lifestyle habits, etc., accordingly.

[0078] Preferably, the curve comparison chart may further include two change curves: one for the user's body fat and another for their weight. By understanding the relationship between the changes in their body fat and weight based on the changes in the curve comparison chart, users can not only focus on their weight but also on the changes in their body fat, thereby appropriately adjusting their body data in terms of diet, exercise, etc., and ensuring that they achieve their weight loss goals while remaining healthy.

[0079] Preferably, the graph may further include a curve showing the change in body fat, allowing the user to intuitively understand the changes in their physique achieved through fitness training or other methods based on the changes in the graph.

[0080] Preferably, the curve comparison chart may further include two curves showing the user's heart rate and body fat changes, which helps the user understand in detail the relationship between their heart condition and body fat, and shows the user that it is necessary to maintain a normal body fat percentage to ensure heart health.

[0081] Preferably, after the curve comparison chart is displayed on the user display screen, personalized recommendations related to the user's lifestyle, generated based on the user's physical data such as weight, body fat, and muscle mass, may be included. For example, the content displayed on the user display screen may further include suggestions for the user's daily energy intake, suggestions for the energy expenditure required for the user's daily exercise, suggestions for the user's daily water intake, and recommended daily exercises. Personalized recommendations allow the user to more rationally achieve goals such as weight loss and muscle gain based on their own physical data.

[0082] Unlike existing technologies, the control method according to the present invention is applied to a body fat scale, and the body fat scale identifies the user's foot movements in the wake-up state and controls the user display screen of the body fat scale based on the foot movements. Compared with conventional control methods for body fat scales, the method used in the present invention, which identifies the user's foot movements to control the body fat scale, simplifies the operation of controlling the user display screen of the body fat scale by controlling the user's foot movements. This eliminates the need for the user to download an app or squat down and pick up the body fat scale, thereby simplifying user operation and improving the convenience of controlling the user display screen of the body fat scale, allowing the user to interact with the body fat scale more easily.

[0083] In one application scenario, the body fat scale enters a wake-up state when it detects that both of the user's feet are standing on the scale, and then opens the user display screen. On the current page, the body fat scale acquires the user's vibration information relative to the scale and controls the switching of options on the current page if it determines that the user's foot movement is a single click; controls the selection of options on the current display screen or the user's body data if it determines that the user's foot movement is a double click; controls the switching of the current page to another page if it determines that the user's foot movement is a single click; and controls the turning off the body fat scale if it determines that the user's foot movement is a long press.

[0084] Naturally, in other application scenarios, the correspondence between foot movement types and operations on the user-displayed screen may be set according to the user's own operating habits, or other foot movement types and operations may be added, and this is not specifically limited.

[0085] In another embodiment, the user display screen is controlled according to different control modes using the method shown in Figure 8, and Figure 8 is a flowchart of one embodiment in which the body fat scale according to the present invention controls the display screen according to different control modes. The method of this embodiment includes steps 81 to 83.

[0086] In step 81, the system enters the wake-up state and acquires the control mode.

[0087] Specifically, the body fat scale enters the wake-up state using the method described in step 11, which will not be repeated here. The control mode is one of two modes that control how the body fat scale displays the user display screen, and the user may select it themselves on the user display screen.

[0088] In step 82, if the control mode is foot control mode, the step of identifying the user's foot movements in the wake-up state is performed.

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

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

[0091] Specifically, if the current control mode of the body fat scale is automatic control mode, the user display screen of the body fat scale will switch within a predetermined time interval. For example, if the predetermined time interval is 3 seconds, the current user display screen of the body fat scale will automatically switch to the next user display screen within 3 seconds.

[0092] In one embodiment of the present invention, if the body fat scale does not detect foot movement within a predetermined time, it automatically switches pages and controls the display screen to perform operations on the user-displayed screen, for example. The length of the predetermined time may be set before shipment or set by the user as needed, and is not limited herein.

[0093] The method of the above embodiment may also be implemented using a body fat analyzer, which will be described below with reference to Figure 9, which is a schematic configuration diagram of the first embodiment of the body fat analyzer according to the present application.

[0094] As shown in Figure 9, the body fat scale 90 of this embodiment includes a case 91, a processor 92, and a motion detection sensor 93. The case 91 is equipped with a display that shows a user display screen or a projection device that projects a user display screen. The processor 92 is installed inside the case 91 and, in a wake-up state, identifies the user's foot movements and controls the user display screen displayed on the body fat scale based on the foot movements.

[0095] Compared to 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 controlling the user display screen of the body fat scale 90 based on the user's foot movements. This simplifies the user's operation to control the user display screen of the body fat scale 90, eliminating the need for the user to download an app. Furthermore, it allows the user to interact with the body fat scale 90 more easily.

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

[0097] The body fat scale 90 may be equipped with a display or other device, which may show a user-defined screen. Alternatively, the body fat scale 90 may be equipped with a projection device, and after entering wake-up mode, the body fat scale 90 may control the projection device to project the user-defined screen onto a projection receiving area, such as the ground or a wall. 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 installed in a case and connected to a processor 92, which acquires user motion information on the body fat scale, and the processor 92 determines the user's foot movements based on the motion information.

[0099] Compared to conventional body fat scales, the body fat scale 90 in this embodiment has a motion detection sensor installed on its surface. The motion detection sensor 93 acquires user motion information on the body fat scale, and the processor 92 determines the user's foot movements based on the motion information. When the user steps on the body fat scale while performing foot movements toward it, the body fat scale vibrates. In this embodiment, the body fat scale can accurately acquire the user's motion information on the body fat scale using the vibration sensor, thereby improving the accuracy of the interaction.

[0100] In one embodiment of the present invention, the motion detection sensor 93 includes a vibration sensor, the motion information includes vibration information, and the vibration sensor acquires 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 an object by detecting minute displacements or changes in velocity caused by vibrations on the object's surface. When a user performs foot movements on a body fat scale, they step on the scale, causing it to vibrate. In this embodiment, the vibration sensor allows the body fat scale to accurately acquire information about the user's movements on the scale.

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

[0103] An accelerometer is a sensor that detects vibration conditions by measuring the acceleration of an object. Accelerometers are usually manufactured using MEMS (Micro-Electro-Mechanical Systems), and their operating principle is based on Newton's second law. When an object vibrates, the accelerometer measures the object's acceleration and calculates the object's vibration characteristic parameters, i.e., vibration information.

[0104] An accelerometer is a sensor that measures the velocity of an object. It can detect and measure the velocity of an object and convert it into an electrical signal. The accelerometer generates electromagnetic induction using a single electromagnetic coil. This electromagnetic induction changes when the object vibrates, and the sensor measures the vibration information of the object based on the changed electromagnetic induction.

[0105] Displacement sensors, also known as linear sensors, are linear devices belonging to the metal induction category, and their role is to convert various physical quantities to be measured into electrical quantities. For example, a potentiometer-type displacement sensor measures vibration information of an object by converting the mechanical displacement of an object (e.g., vibration displacement of the surface of a body fat scale) into an impedance or voltage that has a linear or arbitrary functional relationship with the mechanical displacement of the object, using a potentiometer element, and outputting it as an output.

[0106] In a force sensor, four strain gauges form a Wheatstone bridge, and because the strain gauges are firmly attached to an elastic body, the strain gauges deform in the same way as the elastic body, and the impedance changes as the small-volume force sensor is customized. The output signal of the Wheatstone bridge provides information about these deformations, and in this way, the magnitude of the force acting on the strain gauges can be calculated and information about the vibration of the object can be measured.

[0107] The vibration sensor may be a piezoelectric vibration sensor, which can detect and measure vibrations by converting the mechanical vibrations of an object into electrical signals.

[0108] In one embodiment of the present invention, a body fat analyzer 90 is equipped with a foot movement area and a display area. The user display screen is shown in the display area, and the foot movement detection sensor 93 is installed in the foot movement area, so that the foot movement area and the display area do not overlap.

[0109] By separating the foot movement area and the display area, it is possible to reduce visual interference from the feet to the user display screen, thereby improving the accuracy of controlling the user display screen. Furthermore, it is possible to prevent situations where the user cannot clearly see the data information on the user display screen due to obstruction by the feet.

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

[0111] Area sensitivity refers to the threshold of vibration change that a region recognizes as foot movement after receiving vibration information. Because the area sensitivity is highest in the optimal foot area of ​​the foot movement region, the foot movements acquired by the body fat scale when the user is naturally standing on the body fat scale are the most accurate foot movements, and foot movements performed by the user in the optimal foot area can be accurately and quickly identified by the body fat scale. The motion detection sensor 93 may be installed corresponding to the optimal foot area.

[0112] Both the display area and the foot movement area are located on the side facing the user in case 91, and these two areas may be flush with each other or may have a certain difference in height.

[0113] In another embodiment, as shown in Figures 10 to 12, Figure 10 is a schematic perspective view of a second embodiment of the body fat analyzer according to the present invention. Figure 11 is a schematic plan view of the embodiment of Figure 10. Figure 12 is a schematic bottom view of the embodiment of Figure 10. The display 111 is installed in the center front of the case 91, and other positions may be set as the foot movement area, and a bracket and battery box may be installed on the downward side of the case 91.

[0114] The foregoing 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 transformation, or any direct or indirect application in other related technical fields, made using the contents of the specification and drawings of the present application is also included within the scope of protection of the present application.
