Description

Measuring method, measuring device, wearable device and measuring system

Technical Field

The embodiment of the disclosure relates to the field of intelligent electrical appliances. And more particularly to a measurement method, a measurement device and wearable device, and a measurement system.

Background

The body fat scale can measure parameters such as the fat content, the muscle content, the body fluid specific gravity and the like of a human body besides the weight of the human body, and has important significance in the aspects of health care, weight losing, body building and the like. The basic principle of body fat scale detection is bioelectrical impedance method (BIA), and through weak current in human body, the components of fat, muscle and the like in human body have different electrical conductivities, and different body impedances are generated. And calculating the contents of various human body components by using the measured impedance and combining information such as sex, age, height, weight and the like. The bioelectrical impedance method is simple in measurement and convenient to use, and is the most main measurement method of the professional body fat scales and the household body fat scales at present.

For the household body fat scale, the smart phone is usually connected with the body fat scale through the bluetooth communication technology. After connection, the entire measurement process can be controlled by the application installed on the smartphone. The user can measure body parameters such as body weight, fat content, muscle content, specific gravity of body fluid, etc. by the body fat scale. After measurement, the body fat scale transmits the acquired human body parameters to a smart phone of the user in a Bluetooth transmission mode, so that the user can check the measurement result in the mobile phone application.

Furthermore, since the human body parameters may relate to a variety of data, it is often necessary to present the user with a plurality of items when displayed. Thus, a typical user can only view the complete measurement data in a cell phone application, while typically only the user's weight is displayed at the body fat scale, for example.

Disclosure of Invention

Embodiments according to the present disclosure relate to a measurement method, a measurement device and a wearable device, and a measurement system.

In a first aspect of embodiments of the present disclosure, a measurement method is provided. The method includes if a trigger signal is received at the wearable device indicating that the measurement device activates the measurement, the wearable device determining a desired display mode of the user input, the desired display mode indicating a target display device for which the user desires to display the measurement result. The method also includes the wearable device generating a control signal based on the desired display mode and transmitting the control information to the measurement device to cause the measurement device to display the measurement result at the target display device based on the control signal, the wearable device being in human body communication with the measurement device.

By the method according to the first aspect of the present disclosure, a user can be enabled to flexibly select a display device on which measurement results are to be displayed based on a usage scenario. For example, in public places, the user may not want the measurement to be seen by others, and may therefore choose to display the measurement on the wearable device. In a private setting, however, the user may wish to intuitively display the measurement results on the measurement device. In this way, diversified requirements of the user on the functions of the equipment can be met, and the user experience is improved.

In some embodiments, the wearable device may receive a user selection for one of the at least one candidate display devices available to display the measurement and determine a desired display mode based on the user selection. At least one candidate display device may be displayed on a display screen of the wearable device in a selection list to enable a user to intuitively know the candidate devices that are capable of displaying the measurement results.

In some embodiments, the wearable device may receive voice instructions or motion instructions from the user as a user selection.

In some embodiments, the user selection may be input to the wearable device through a touch screen of the wearable device or a key or knob disposed on the wearable device.

The user's selection of the desired display mode can be input to the wearable device in a number of ways for at least one candidate display device displayed on the display screen. For example, a desired display mode is selected by an action of the user. The user may directly click on an entry of one of the candidate display devices displayed on the touch screen to enter the desired target display device. The user may also turn a knob of the wearable device to scroll through the entries of at least one candidate display device displayed on the display screen to select a desired target display device. Further, the wearable device may be configured to be capable of receiving voice instructions from a user. For example, the user may speak a desired display device selected from the at least one candidate display device. The wearable device may understand semantics of the voice instructions entered by the user and select a corresponding candidate display device according to the semantics. In this way, the user's selection of a desired display device can be achieved in a flexible manner.

In some embodiments, the target display device may be a wearable device or a measurement device to meet the display requirements of the user for the measurement results under different scenarios.

In some embodiments, the control signal may be transmitted to the measurement device via the body of the user, thereby enabling a human body communication process between the wearable device and the measurement device. The communication mode can have higher safety and does not need a complex communication connection establishment process, so the method is particularly suitable for the transmission of private data such as human body parameters of a user.

In some embodiments, when the measurement device has a communication function other than human body communication, the display mode may further include an alternative entry to display the measurement result on other display devices. Other display devices may include, for example, portable computers, desktop computers, tablet computers, smart phones, medical human body sign monitoring devices, smart appliances, and smart sports equipment, among others. In this way, it is possible to enable the display of application scenarios of the measuring device at more target devices and thus lead to the selection of more display modes. For example, at a physical examination facility, a fitness venue, a slimming facility or a medical facility, the measurement results of the user can be further displayed, for example, on an expansion device that can provide the user with parameters associated with the human body, so as to provide the user with expansion functions such as health status assessment, slimming planning, exercise monitoring and the like, thereby further improving the quality of life of the user.

In some embodiments, if the wearable device determines that the user desires to display the measurement at the wearable device, the wearable device may receive a measurement signal from the measurement device. The measurement signal may be an electrical impedance signal. The wearable device may calculate a measurement from the measurement signal and display the measurement at the wearable device.

In some embodiments, if the wearable device determines that the user desires to display the measurement at the measurement device, an adjustment signal for adjusting the display of the measurement at the measurement device may be sent to the measurement device. Due to the limited display area of the display device of the measurement device, for example, the human body physical sign parameters generated by the measurement can be displayed on different pages. In this scenario, the adjustment signal may be, for example, a page flip instruction. In some embodiments, the user may click on the wearable device touchscreen to enter a page turn instruction, similar to entering an indication of a desired display mode. Optionally, the user may input the page turning instruction through a knob or a key provided on the wearable device. For another example, the user may also input a page turn instruction through a voice instruction or a specific motion. In this way, the display of the measurement results at the measuring device can be adjusted according to the way in which the user is interested, the function expansion of the measuring system for the individualized difference of different users is highlighted, and the user experience and the interestingness of the product are further improved.

In some embodiments, the measurement device may be a body fat meter. The wearable device may be a smart bracelet or a smart watch.

In a second aspect of embodiments of the present disclosure, a measurement method is provided. The method includes generating a trigger signal for indicating activation of the measurement if the measurement device detects contact between the user and the measurement device. The method also includes sending the trigger signal to a wearable device and receiving a control signal from the wearable device. The control signal may include a desired display mode input by the user. The desired display mode may indicate a target display device that the user desires to display the measurement results. The method also includes causing the measurement result to be displayed at a target display device based on the control signal, the wearable device being in human body communication with the measurement device.

In some embodiments, the measurement device may generate a measurement signal associated with a user and determine a desired display mode of the user input based on the control signal. The measurement device may also determine a target display device on which the user desires to display the measurement result according to a desired display mode input by the user. If the measurement device determines that the measurement result is displayed at the measurement device, a measurement result is generated based on the measurement signal and displayed at the measurement device.

In some embodiments, if the measurement device determines to display the measurement at the wearable device, a measurement signal is sent to the wearable device such that the measurement is displayed at the wearable device. Thus, the user can select the display mode of the measurement results based on different usage scenarios in which the measurement system is located. For example, in public places, a user may not desire to display human vital parameters on a measurement device due to the risk of privacy leakage. In a private environment, however, the user may desire to have these human body vital parameters intuitively known during the measurement process. Through the scheme of the embodiment of the disclosure, the measurement requirements of the user in different scenes can be met.

In some embodiments, the measurement device may receive the control signal via the body of the user.

In embodiments of the present disclosure, human body communication between a measurement device and a wearable device is enabled. Since the human body communication adopts low-frequency signal transmission and uses the human body as a carrier to transmit signals, it is difficult for unauthorized persons or equipment to intercept the private data of the user. Meanwhile, the human body communication mode can avoid generating electromagnetic noise and can work in a low power consumption mode, so that the data safety and reliability in the information interaction process are improved.

In some embodiments, the measurement device may receive an adjustment signal from the wearable device for adjusting the display of the measurement result at the measurement device and adjust the display of the measurement result at the measurement device based on the adjustment signal. The adjustment signal may be, for example, a page flip instruction. This is because the display area of the display device of the measurement device is limited, and thus the human body sign parameters may be displayed on different pages. The adjustment signal may also relate to, for example, an adjustment to the display font and style. In this way, the display of the measurement results at the measuring device can be adjusted according to the way in which the user is interested, the function expansion of the measuring system for the individualized difference of different users is highlighted, and the user experience and the interestingness of the product are further improved.

In a third aspect of embodiments of the present disclosure, a wearable device is provided. The wearable device may include a processor and a memory coupled with the processor. The memory holds instructions that need to be executed, which when executed by the processor cause the wearable device to perform the method according to the first aspect.

In a fourth aspect of embodiments of the present disclosure, a measurement device is provided. The measurement device may include a processor and a memory coupled to the processor. The memory holds instructions that need to be executed, which instructions, when executed by the processor, cause the measurement device to perform the method according to the second aspect.

In a fifth aspect of embodiments of the present disclosure, a measurement system is provided. The measurement system may comprise a wearable device according to the third aspect and a measurement device according to the fourth aspect.

Through the measuring system of the embodiment of the disclosure, the individualized display of the measuring result based on the use scene can be realized. In this way, on the one hand, the safety of user privacy is guaranteed, and the risk of personal data leakage is avoided. On the other hand, diversified using modes can be provided for the user, and the user experience is improved.

Detailed Description

Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.

In describing embodiments of the present disclosure, the terms "include" and its derivatives should be interpreted as being inclusive, i.e., "including but not limited to. The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions are also possible below.

As described above, the body fat scale can measure parameters such as body fat content, muscle content, body fluid specific gravity, etc. in addition to body weight, and has important significance in health care, weight reduction, body building, etc. The basic principle of body fat scale detection is bioelectrical impedance method (BIA), and through weak current in human body, the components of fat, muscle and the like in human body have different electrical conductivities, and different body impedances are generated. And calculating the contents of various human body components by using the measured impedance and combining information such as sex, age, height, weight and the like. The bioelectrical impedance method is simple in measurement and convenient to use, and is the most main measurement method of the professional body fat scales and the household body fat scales at present.

For the household body fat scale, the smart phone is usually connected with the body fat scale through the bluetooth communication technology. After the connection, the entire measurement process can be controlled, for example, by an application installed on the smartphone. For example, a user measures body parameters such as body weight, fat content, muscle content, specific gravity of body fluid, and the like, of a human body by a body fat scale. After measurement, the body fat scale transmits the acquired human body parameters to a smart phone of the user in a Bluetooth transmission mode, so that the user can obtain a measurement result in mobile phone application.

The connection of the body fat scale with the smart phone through the bluetooth communication mode has the disadvantage that a user who expects to use the body fat scale for measurement needs to firstly ensure that the bluetooth connection between the measurement equipment and a user who uses the measurement equipment before is disconnected, and then the connection with the measurement equipment can be established. Furthermore, there may be a potential privacy security risk, for example, measurement data of a previous user of the measurement device may be transmitted to a subsequent user of the measurement device, and the security of the data may not be guaranteed.

The currently used body fat scales are also undesirable in that, since body parameters may relate to a variety of data, it is often necessary to present the user with a plurality of items when displayed. Typically the user can only view the complete measurement data in a mobile phone application, whereas typically only the user's weight is displayed at the body fat scale, for example. Therefore, the display mode of the current body fat scale is single, the flexibility is poor, and the user experience is poor.

Accordingly, embodiments of the present disclosure provide a measurement method and a measurement system. The measurement system comprises a body fat scale and a wearable device matched with the body fat scale. In the measurement process, information interaction between the body fat scale and the wearable device is realized through a human body communication mode. Further, a target display device that the user desires to display the measurement result may be selected by the wearable device. In this way, on the one hand, the safety of user privacy is guaranteed, and the risk of personal data leakage is avoided. On the other hand, diversified using modes can be provided for the user, and the user experience is improved.

FIG. 1 shows a schematic diagram of an exemplary measurement system according to an embodiment of the present disclosure. As shown in fig. 1, measurement system 100 may include a measurement device 120 and a wearable device 110. The wearable device 110 may be worn by the user 130 and the wearable device 110 establishes a connection with the measurement device 120 through human body communication when the user 130 stands with both feet on the measurement device 120.

The measurement device 120 may comprise, for example, a home scale, a commercial scale, a medical scale, or any other device capable of measuring basic body parameters of a user. Here, the basic human body parameters may include, for example, body weight, fat content, muscle content, moisture content, basal metabolic rate, bone mass, protein content, visceral fat content, Body Mass Index (BMI), and the like. The wearable device 130 may include, for example, a smart watch, smart bracelet, smart armband, or the like that may be worn by the user and may be in contact with the user's skin.

During the measurement process, information interaction between the measurement device 120 and the wearable device 110 can be realized through human body communication. The human body communication is a communication method for transmitting signals by using a human body as an information channel. The human body can be regarded as a conductor, and the signal conduction is completed by using the human body as a channel. The human body communication frequency is generally 10kHz-100MHz, and the signal is a carrier signal.

For example, when user 130 stands on measurement device 120, measurement device 120 may generate a trigger signal. The trigger signal may be a pulse signal. For example, the trigger signal may indicate that user 130 has stood on measuring device 120 in preparation for a measurement. The trigger signal may be transmitted to the wearable device 110 via the body of the user 130. Upon receiving the trigger signal, wearable device 110 may generate and transmit control information to measurement device 120 via the body of user 130 based on the display mode desired by the user, to enable the measurement to be displayed at the target display device at which the user desires the measurement to be displayed based on the control signal. The target display device may be, for example, the wearable device 110 or the measurement device 120.

In addition, as shown in fig. 1, the measurement device 120 may further include a display screen 124 for displaying the measurement result. The wearable device 110 may include a display screen 114 for displaying the measurement results.

For example, as shown in fig. 1, when the user 130 has stood on the measurement device 120 ready to make a measurement, the trigger signal may be transmitted to the wearable device 110 via the body of the user 130. After receiving the trigger signal, the display screen 114 of the wearable device 110 may display a display mode that is selectable by the user 130.

In an application scenario where the wearable device 110 is a watch and the measurement device 120 is a body fat scale, the display modes displayed on the wearable device 110 that are selectable by the user 130 may include a watch display or a body fat scale display. The user 130 may click on the display screen 114 to select a desired display mode.

In one implementation, if the user chooses to display the measurement at a body fat scale, the control information entered by the user by clicking on the wearable device 110 is transmitted to the measurement device 120 via the user's body. Thus, the measurement results of the user 130 may be displayed at the display screen 124 of the measurement device 120. The measurements displayed at the display screen 124 may include, for example, body weight, fat content, muscle content, moisture content, basal metabolic rate, bone mass, protein content, visceral fat content, and BMI, among others.

In one implementation, if the user selects to display the measurement at the watch, after the user clicks the watch display option, control information is transmitted to the measurement device 120 via the user's body, enabling the measurement device 120 to transmit the measurement information to the wearable device 110 via the user's 130 body. The wearable device 110 may calculate a measurement result from the measurement signal and display the measurement structure at the display screen 114. The measurements displayed at the display screen 114 may include, for example, body weight, fat content, muscle content, moisture content, basal metabolic rate, bone mass, protein content, visceral fat content, and BMI, among others.

The basic idea and principle of the present disclosure can be explained in detail by fig. 2 to 9. Fig. 2 shows a signaling diagram 200 of an example measurement procedure in accordance with an embodiment of the present disclosure. Hereinafter, information interaction between the measurement device 120 and the wearable device 110 in the measurement process according to an embodiment of the present disclosure is first set forth in detail in conjunction with fig. 2. For clarity, the measurement process will be described in connection with the measurement system 100 shown in FIG. 1.

When measuring device 120 detects that contact has occurred between user 130 and measuring device 120, measuring device 120 generates 202 a trigger signal to indicate activation of the measurement process. The measurement device 120 may send 204 the trigger signal to the wearable device 110. The trigger signal may be a pulse signal or the like.

When the wearable device 110 receives the trigger signal, the wearable device 110 may determine that the measurement process has been activated. The indication that the measurement process is activated may be displayed, for example, on the display screen 114 of the wearable device 110 to enable the user to initiate selection of a display mode for the measurement results. As shown in the user interface 115 shown in fig. 1, the display modes displayed on the wearable device 110 may include a watch display and a body fat scale display. By providing the user 130 with a plurality of different display modes for the measurement results, the measurement results can be caused to be provided to the respective display devices according to the user's desires. For example, in public places, the user may not want the measurement results to be displayed at the measurement device from others, so the user may choose to display the measurement results at the wearable device at this time. In a private setting, however, the user may wish to intuitively display the measurement results on the measurement device. The selection of the display mode can provide a user with a degree of flexibility in use based on the use scenario. In this way, diversified requirements of the user on the functions of the equipment can be met, and the user experience is improved.

Wearable device 110 may in turn detect 206 a desired display mode input by user 130. The desired display mode may be input to the wearable device 110, for example, by the user clicking on the display screen 114 or keys of the wearable device 110. The user 130 may also input an indication of the selection of a desired target display device through voice instructions or a particular action.

In some embodiments, when the measurement device has a communication function other than human body communication, the display mode may further include an alternative entry to display the measurement result on other display devices. Other display devices may include, for example, portable computers, desktop computers, tablet computers, smart phones, medical human body sign monitoring devices, smart appliances, and smart sports equipment, among others.

In this way, it is possible to enable the display of application scenarios of the measuring device at more target devices and thus lead to the selection of more display modes. For example, at a physical examination facility, a fitness venue, a slimming facility or a medical facility, the measurement results of the user can be further displayed, for example, on an expansion device that can provide the user with parameters associated with the human body, so as to provide the user with expansion functions such as health status assessment, slimming planning, exercise monitoring and the like, thereby further improving the quality of life of the user.

As an example, a list may be displayed on the display screen 114, for example, including at least one candidate display device that may be used to display the measurement results. When user 130 notices the list presented on display screen 114, user 130 may output an instruction to indicate a user selection of one of the at least one candidate display device.

In some embodiments, such as shown in reference to the user interface 115 of fig. 1, the user 130 may click on a touch screen of the display screen 114 of the wearable device 110 to select a desired target display device. Alternatively, the user 130 may scroll through the entries on the list by a knob or key provided on the wearable device 110 to select the desired target display device. As another example, user 130 may also select a desired target display device via voice instructions. As another example, user 130 may also select a desired target display device by a particular action. In this way, the user 130 may input, in a flexible and easy manner, the user's indication of the target device for which display of the measurement results is desired through the wearable device 110.

If wearable device 110 detects a user selection of one candidate display device from user 130, wearable device 110 may determine the user selection as the desired display mode of the user input. Based on the indication, wearable device 110 may generate a control signal and send 208 the control signal to measurement device 120. For example, if the user selects to display the measurement at the wearable device 110, a control signal may be generated and indicate that the user's selection is to display the measurement at the wearable device 110. Whereas if the user selects to display the measurement at measurement device 120, a control signal may be generated and indicate to the user that the selection is to display the measurement at measurement device 120.

When the measurement device 120 receives the control signal, the measurement device 120 may determine 210 a target display device that the user desires to display the measurement result based on the control signal. In some embodiments, if the measurement device 120 determines that the user 130 desires to display the measurement results at the wearable device 110, the measurement device 120 may send 212 an electrical impedance signal associated with the user 130 generated during the measurement process to the wearable device 110.

The wearable device 110 may receive the electrical impedance signal. At the wearable device 110, the human vital sign parameters may be calculated based on the electrical impedance signals. For example, referring to what is shown in the user interface 116 of fig. 1, the user's measured body weight, body fat rate, muscle rate, moisture, bone mass, etc. as measurements may be displayed 214 at the display screen 114 of the wearable device 110.

In some embodiments, if measurement device 120 determines that user 130 desires to display the measurement at measurement device 120, measurement device 120 may calculate the human vital signs parameters based on the electrical impedance signals associated with user 130 generated during the measurement process. The measurement device 120, in turn, may display 216 the user measured body weight, body fat rate, muscle rate, bone mass, protein rate, etc. human physical sign parameters as measurements at the display screen 124 of the measurement device 120, such as shown with reference to the user interface 125 of fig. 1.

Thus, user 130 may select a display mode for the measurement results based on the different usage scenarios in which measurement system 100 is located. For example, in public places, user 130 may not desire to display human vital parameters on measurement device 120 due to the risk of privacy leakage. In a private environment, however, user 130 may desire to have these human body vital parameters intuitively known during the measurement process. Through the embodiment scheme of the disclosure, the measurement requirements of the user 130 under different scenes can be met.

In some embodiments, if measurement device 120 determines that user 130 desires to display the measurement at measurement device 120, user 130 may issue instructions through wearable device 110 to adjust the display of the measurement at measurement device 120 in the course of user 130 viewing the measurement at measurement device 120. Due to the limited display area of the display screen 124 of the measurement device 120, for example, the human body sign parameters generated by the measurement can be displayed on different pages. In this scenario, the instruction may be, for example, a page turn instruction. In some embodiments, similar to entering an indication of a display mode, the user 130 may click on a touch screen of the display screen 114 of the wearable device 110 to enter a page flip instruction. Alternatively, the user 130 may input the page turning instruction through a knob or a key provided on the wearable device 110. For another example, the user 130 may also input a page turning instruction through a voice instruction or a specific motion. For example, referring to what is shown in user interface 117 of FIG. 1, a user may select to scroll to the next page or to the previous page by clicking on display screen 114 to control

user interface

125 or 126 presented at display screen 124.

In this way, the measurement results can be displayed at the measurement device 120 in a manner that is of interest to the user, highlighting the functional expansion of the measurement system for individualized differences among different users, further improving the user experience and the enjoyment of the product.

It has been mentioned above that the information interaction between the measurement device 120 and the wearable device 110 shown in fig. 2 is implemented by means of human body communication. The human body communication process may be implemented by respective transceivers arranged at the measurement device 120 and the wearable device 110. Furthermore, in the human body communication technology, since the electrodes are adopted to couple signals to the human body instead of the antennas for communication between the measurement device 120 and the wearable device 110, the arrangement of the electrodes at the measurement device 120 and the wearable device 110 is particularly important for the quality and efficiency of information interaction. The structures of the measurement device 120 and the wearable device 110 and the corresponding electrode arrangements in embodiments according to the present disclosure are described further below in conjunction with fig. 3-7C.

Fig. 3 shows a block diagram of a wearable device 110 according to an embodiment of the disclosure. Fig. 4 shows a block diagram of a measurement device 120 according to an embodiment of the present disclosure. As shown in fig. 3, the wearable device 110 may include an instruction input 111, a transceiver 112, a controller 113, and a display screen 114. As shown in fig. 4, the measurement device 120 may include a measurement component 121, a transceiver 122, a controller 123, and a display screen 124.

The operation of the measurement process 200 shown in fig. 2 at the measurement device 120 and the wearable device 110 will be further described in detail below in conjunction with fig. 3 and 4.

After the measurement device 120 detects that contact between the user 130 and the measurement device 120 has occurred to generate a trigger signal, the trigger signal may be sent to the transceiver 112 of the wearable device 110 through the transceiver 122. The transceiver 122 of the measurement device 120 and the transceiver 112 of the wearable device 110 may include human body communication chips for enabling human body communication between the measurement device 120 and the wearable device 110, respectively.

The transceiver 112 of the wearable device 110 may transmit the trigger signal to the controller 113. The controller 113 may determine that the measurement process has been activated based on the trigger signal. In some embodiments, the controller 113 may generate and transmit an indication that the measurement process is activated to the display screen 114 of the wearable device 110, so that the user may be aware of the activation of the measurement process and in turn start inputting a selection of a display mode for the measurement result.

The instruction inputter 111 of the wearable device 110 may detect a desired display mode input by the user 130. The controller 113 may display at the display screen 114 at least one candidate display device including information that may be used to display the measurement results. As described above, the desired display mode input by the user 130 can be provided to the instruction input device 111 in various ways.

In some embodiments, the user 130 may, for example, click on a touch screen of the display screen 114 of the wearable device 110 to indicate that one of the candidate display devices in the list is selected as the target display device. Alternatively, the user 130 may input an indication of a desired target display device selected from the list of candidate display devices by operating a knob or key provided on the wearable device 110. As another example, user 130 may also input an indication of a selection for a desired target display device through voice instructions or a particular action. In this way, the user 130 may input, in a flexible and easy manner, the user's indication of the target device for which display of the measurement results is desired through the wearable device 110.

The desired display mode input by the user 130 detected by the instruction inputter 111 may be provided to the controller 113. The controller 113 may generate a control signal, for example, based on the indication. The control signal may be transmitted through the transceiver 122 of the measurement device 120 via the body of the user by the transceiver 112 of the wearable device 110.

The transceiver 122 of the measurement apparatus 120, after receiving the control signal, may transmit the control signal to the controller 123 of the measurement apparatus 120 to determine a target display apparatus on which the user desires to display the measurement result based on the control signal at the controller 123.

In some embodiments, if the controller 123 of the measurement device 120 determines that the user 130 desires to display the measurement results at the wearable device 110, the controller 123 may provide electrical impedance signals associated with the user 130 generated during the measurement process to the transceiver 122 of the measurement device 120. The transceiver 122 may transmit the electrical impedance signal to the transceiver 112 of the wearable device 110 via the user's body.

At the wearable device 110, upon receiving the electrical impedance signal at the transceiver 112, the controller 113 of the wearable device 110 may calculate the human vital signs parameter based on the electrical impedance signal. The controller 113 may then send these human body sign parameters as measurements to the display screen 114 to display the measurements at the display screen 114.

In some embodiments, if the controller 123 of the measurement device 120 determines that the user 130 desires to display the measurement at the measurement device 120, the controller 123 may calculate the human vital signs parameter based on the electrical impedance signal associated with the user 130 generated during the measurement. The controller 123 may then send these human body sign parameters as measurements to the display 124 to display the measurements at the display 124.

As indicated above, there is a need for a user to select the display of measurement results for different usage scenarios. For example, in public places, user 130 may not desire to display human vital parameters on measurement device 120 due to the risk of privacy leakage. In a private environment, however, user 130 may desire to have these human body vital parameters intuitively known during the measurement process. By providing separate controllers at both the measurement device 120 and the wearable device 110, the above-mentioned needs of the user are more simply fulfilled.

In addition, since the transceiver 122 of the measurement device 120 and the transceiver 112 of the wearable device 110 each include a human body communication chip, human body communication between the measurement device 120 and the wearable device 110 is enabled. Since the human body communication adopts low-frequency signal transmission and uses the human body as a carrier to transmit signals, it is difficult for unauthorized persons or equipment to intercept the private data of the user. Meanwhile, the human body communication mode can avoid generating electromagnetic noise and can work in a low power consumption mode, so that the data safety and reliability in the information interaction process are improved.

It should be understood that the target display device may also include other devices capable of interfacing with the measurement device 120, such as a computer, laptop computer, desktop computer, tablet computer, smart phone, medical human body sign monitoring device, smart appliance, smart sports equipment, and the like. In this case, the transceiver 122 of the measurement apparatus 120 may further include other communication elements besides the human body communication chip, for example, a communication element capable of supporting other wired or wireless communication modes. By means of the transceiver 122 of the measurement device 120, a coordinated operation of a plurality of devices associated with human health care can be achieved, thereby providing flexible extension possibilities for the measurement system.

Further, in some embodiments, if user 130 desires to display the measurement at measurement device 120, during viewing of the measurement by user 130 at measurement device 120, user 130 may input instructions through instruction input 111 of wearable device 110 to adjust the display of the measurement at display screen 124 of measurement device 120.

For example, due to the limited display area of the display screen 124, the measurement-generated human vital parameters may be distributed on different pages. In this scenario, the user 130 may input a page flipping instruction through the instruction inputter 111 of the wearable device 110 so that the user 130 can review the complete measurement result.

For another example, since the user 130 may have different attention needs for the human body sign parameters in the measurement results, for example, the user 130 has a higher attention degree for the body fat content than for the body weight, the user 130 may input a zoom instruction on the display interface and an output mode instruction associated with different presentations of the measurement results on the display interface through the instruction input device 111 of the wearable device 110, and the like. In this way, the measurement results can be displayed at the measurement device 120 in a manner that is of interest to the user, highlighting the functional expansion of the measurement system for individualized differences among different users, further improving the user experience and the enjoyment of the product.

In some embodiments, if user 130 desires to save the measurement at the device displaying the measurement, user 130 may enter an instruction to save the measurement through instruction inputter 111 of wearable device 110. For example, if the measurement result is displayed through the wearable device 110, the instruction inputter 111 may transmit the instruction to the controller 113 of the wearable device 110 to save the measurement result at the controller 113, or be provided at a storage unit (not shown) in the wearable device 110.

For another example, if the measurement result is displayed by the measurement device 120, the instruction inputter 111 may transmit the instruction to the controller 113 of the wearable device 110 to generate a further control signal that controls storing the measurement result. The control signal is transmitted, for example, from the transceiver 112 of the wearable device 110 via the user to the transceiver 122 of the measurement device 120. The transceiver 122 may transmit the further control signal to the controller 123 of the measurement device 120 in order to save the measurement result at the controller 123 or be provided at a storage unit (not shown) in the measurement device 120.

It has been pointed out above that the arrangement of the electrodes at the measurement device 120 and the wearable device 110 is particularly important for the accuracy of the measurement results and the efficiency of the information interaction during the measurement and information interaction of the measurement system. Fig. 5A-5C show schematic diagrams of electrode arrangements of a wearable device according to embodiments of the present disclosure. 6A-6C show schematic diagrams of electrode arrangements of a measurement device according to embodiments of the present disclosure. Various electrode arrangements according to embodiments of the present disclosure are described in further detail below in conjunction with fig. 5A-5C and 6A-6C.

Fig. 5A shows a schematic diagram of one implementation of wearable device 110. As shown in fig. 5A, the wearable device 110 may include a display screen 114. As shown in fig. 5B, in some embodiments, wearable device 110 may include electrodes 501 and 502. The electrodes 501 and 502 may be considered as part of the transceiver 112 of the wearable device 110, for example, for human body communication between the wearable device 110 and the measurement device 120. Furthermore, the electrodes 501 and 502 may also be considered as components of other functional units of the wearable device 110, for example, the electrocardiographic monitoring unit 115, for monitoring of further basic vital parameters of the user 130, such as heartbeat, respiration, etc. The electrodes 501 and 502 shown in fig. 5B may be arranged on the side of the wearable device 110 in fig. 5A facing away from the display screen 114, i.e. the side in contact with the skin of a human body.

In some embodiments, the electrodes 501 and 502 may be time multiplexed, for example, by the transceiver 112 and the electrocardiograph monitoring component 115. This time multiplexing may be implemented, for example, by the controller 113 of the user-wearable device 110. For example, the electrode 501 and the electrode 502 are turned off to perform the human body communication function when the electrocardiographic signal is measured, and the electrode 501 and the electrode 502 are turned off to perform the electrocardiographic measurement function when the human body communication is realized.

It is also possible that in some embodiments, as shown in fig. 5C, wearable device 110 may include electrode 501, electrode 502, electrode 503, and electrode 504. For example, the electrode 501 and the electrode 502 may be considered as components of the transceiver 112 of the wearable device 110 for human body communication between the wearable device 110 and the measurement device 120, for example, while the electrode 503 and the electrode 504 may be considered as components of other functional units of the wearable device 110, for example, the electrocardiographic monitoring component 115, for monitoring of further basic vital sign parameters of the user 130, such as heartbeat, respiration, and the like, for example. The wearable device 110 with four electrodes does not need to adopt the time-division multiplexing mechanism. The electrodes 501, 502, 503 and 504 shown in fig. 5 may be arranged on the side of the wearable device 110 in fig. 5A facing away from the display screen 114, i.e. the side in contact with the skin of a human body.

For measurement device 120, in some embodiments, as shown in fig. 6A, measurement device 120 may include electrode 601, electrode 602, electrode 603, and electrode 604. For example, electrodes 601 and 602 may be excitation power supply electrodes, while electrodes 603 and 604 may be, for example, electrical impedance measurement electrodes. The electrodes 603 and 604 can be considered as being part of the measuring part 121 of the measuring device 120, for example.

During the measurement, a high-frequency current is applied to the electrode 601 and the electrode 602, so that a voltage can be measured on the electrode 603 and the electrode 604, and finally an impedance value between the electrode 603 and the electrode 604 can be obtained. The electrical impedance value contains high-frequency excitation source components, and can form a demodulated electrical impedance signal only after being processed by a demodulation circuit, a filter circuit and an amplification circuit.

Furthermore, the electrodes 603 and 604 may for example be considered as an integral part of the transceiver 122 of the measurement device 120 for human body communication between the wearable device 110 and the measurement device 120.

In some embodiments, the electrodes 603 and 604 may be time multiplexed by the transceiver 122 and the electrocardiographic measurement component 121, for example. This time multiplexing can be implemented, for example, by the controller 123 of the measurement device 110. For example, the human body communication function of the electrodes 603 and 604 is turned off when the electrical impedance signal is measured, and the electrical impedance signal measurement function of the electrodes 603 and 604 is turned off when the human body communication is realized.

It is also possible that in some embodiments, as shown in fig. 6B, measurement device 120 may include electrode 601, electrode 602, electrode 603, electrode 604, electrode 605, and electrode 606. For example, electrodes 601 and 602 may be excitation power supply electrodes, while electrodes 603 and 604 may be, for example, electrical impedance measurement electrodes. The electrodes 603 and 604 can be considered as being part of the measuring part 121 of the measuring device 120, for example. During the measurement, a high-frequency current is applied to the electrode 601 and the electrode 602, so that a voltage can be measured on the electrode 603 and the electrode 604, and finally an impedance value between the electrode 603 and the electrode 604 can be obtained. Furthermore, electrode 605 and electrode 606 may be considered as part of transceiver 122 of measurement device 120, for example, for human body communication between wearable device 110 and measurement device 120. The wearable device 110 with six electrodes does not need to adopt the time-division multiplexing mechanism.

In some embodiments, as shown in fig. 6C, measurement device 120 may include electrode 601, electrode 602, electrode 603, electrode 604, electrode 605, electrode 606, electrode 607, and electrode 608. The measuring device 120 with eight electrodes may have different components than the measuring device 120 shown in fig. 1.

Fig. 7 shows a schematic diagram of an exemplary further measurement system 700 according to an embodiment of the present disclosure. In fig. 7, the measurement device 120 may further include, for example, a handheld section 125 connected to the main body of the measurement device 120 (i.e., the user 130 standable area). The hand-held component 125 may be, for example, a handle, a grip, or a pull rod. For example, electrode 601, electrode 602, electrode 603, electrode 604 may be disposed on the body of measurement device 120, while electrode 605, electrode 606, electrode 607, and electrode 608 may be disposed on handheld device 125.

During the measurement, the user 130 may stand on the body of the measurement device 120 with both feet and hold the handheld device 125 with both hands. Thus, in addition to the electrical impedance between the feet, the electrical impedance between the hands and feet can be measured. In this way, the measurement results can be made more accurate.

In the scenario shown in fig. 7, the transceiver 122 of the measurement device 120 may be arranged at the measurement device 120 body. The transceiver 122 may also be disposed in a handheld device 125. Accordingly, the pattern of time division multiplexing of the four electrodes at the body of the measurement device 120 and time division multiplexing of the four electrodes at the handheld device 125 may be implemented as described in connection with fig. 6A.

Different advantages can be achieved by different electrode arrangements. For example, when the transceiver 122 of the measuring apparatus 120 is disposed at the main body of the measuring apparatus 120, since the human body communication chip disposed at the transceiver 122 is located at a short distance from the electrode for communication, it is advantageous for the signal coupling with the human body during the human body communication since the electrode area disposed at the main body of the measuring apparatus 120 can be large and the contact is reliable. When the transceiver 122 of the measurement device 120 is disposed at the handheld device 125, the distance between the electrode for communication on the measurement device 120 side and the electrode for communication on the wearable device 110 side is low, and therefore, less transmission attenuation can be caused, which is advantageous for improvement of communication quality.

Furthermore, as described in the above embodiments, the number of electrodes at the measurement device 120 and the wearable device 110 may be implemented in a variety of ways, thereby providing a more flexible device structure.

In some embodiments, the measurement device may generate a measurement signal associated with the user based on contact between the user and the measurement device. The measurement device determines a display mode based on the control signal and determines a target display device that displays the measurement result based on the display mode. The measurement device may also send the measurement signal to the wearable device such that the measurement result is displayed at the wearable device if the measurement device determines that the display mode indicates that the measurement result is displayed at the wearable device.

In some embodiments, the measurement device may generate a measurement signal associated with the user based on contact between the user and the measurement device. The measurement device determines a display mode based on the control signal and determines a target display device that displays the measurement result based on the display mode. The measurement device may further generate the measurement result based on the measurement signal and display the measurement result if the measurement device determines that the display mode indicates that the measurement result is displayed at the measurement device.

In some embodiments, the measurement device may receive an adjustment signal from the wearable device for adjusting the display of the measurement result at the measurement device and adjust the display based on the adjustment signal.

In an embodiment of the present disclosure, human body communication between the measurement device 120 and the wearable device 110 is enabled. Since the human body communication adopts low-frequency signal transmission and uses the human body as a carrier to transmit signals, it is difficult for unauthorized persons or equipment to intercept the private data of the user. Meanwhile, the human body communication mode can avoid generating electromagnetic noise and can work in a low power consumption mode, so that the data safety and reliability in the information interaction process are improved.

In addition, the embodiment of the disclosure also realizes the selection of the display mode of the measurement result by the user. The display of the measurement results can be selected according to different scenarios of the user using the measurement system.

In a private environment, however, the user may desire to have these human body vital parameters intuitively known during the measurement process. The selection of the display mode provided by the embodiment of the disclosure provides diversified product functions for the user, and improves the customer experience.
