Description

[Technical Field]

[0001] The present invention relates to a terminal device that measures biological information of a subject in a non-contact manner. [Background technology]

[0002] Conventionally, terminal devices that acquire and display measurement results from measuring instruments are known as prior art. In such terminal devices, from the viewpoint of protecting personal information, information such as measurement results is stored on a server with access restrictions, and is managed so as to minimize the amount of information remaining on the terminal device.

[0003] For example, Patent Document 1 discloses a communication terminal that can acquire past measurement history from a server and check it on a calendar screen that is separate from the measurement screen that accepts measurement operations. Measurement history icons are displayed on the calendar, and the measurement status can be seen from the display form of the icons. By selecting an icon of the measurement history, the data for that date is displayed on the screen. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-046962 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above technology, the screen on which the past measurement history can be checked is a screen that is separate from the measurement screen and that acquires the past measurement history from the server. Therefore, in order to check the past measurement history during measurement operation, it is necessary to close the measurement screen once and open another screen that acquires the past history from the server. This leaves room for improvement in terms of efficient measurement work.

[0006] One aspect of the present invention has been made in consideration of the above-mentioned problems, and aims to provide a terminal device or the like that can perform efficient measurement work while ensuring the proper handling of personal information. [Means for solving the problem]

[0007] In order to solve the above problem, a terminal device according to one embodiment of the present invention comprises a measurement processing unit that measures the biometric information of a person being measured based on a photographed image of the person being measured and transmits the measurement results to a server; an authentication processing unit that transmits authentication information for authenticating the person being measured to the server and obtains the authentication results from the server; and a display control unit that displays a measurement screen that accepts measurement operations using the measurement processing unit and the authentication processing unit, and displays a current result screen that includes the authentication results and the measurement results after the measurement operation is completed, and the display control unit displays at least one status icon on the measurement screen that represents, in a display format, the measurement status of measurement operations performed within a predetermined period of time going back from the present. [Effects of the Invention]

[0008] According to one aspect of the present invention, it is possible to provide a terminal device or the like that can perform efficient measurement work while ensuring the appropriate handling of personal information. [Brief explanation of the drawings]

[0010] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail.

[0011] (1. General configuration of terminal device) 1 is a block diagram showing a schematic configuration of a terminal device 100 according to a first embodiment of the present invention. As shown in FIG. 1, the terminal device 100 includes a control unit 1, an image capturing device 2, an input device 3, a display device 4, a communication device 5, a storage device 6, a temperature measuring device 7, a microphone 8, and a speaker 9.

[0012] The terminal device 100 is a device used to measure the biometric information of the subject based on a captured image of the subject (i.e., without contact). Examples of biometric information include, but are not limited to, the subject's body temperature, blood pressure, pulse rate, respiratory rate, etc. The terminal device 100 may be any device that has the function of acquiring and displaying images, and may be, for example, a smartphone or tablet terminal.

[0013] The person taking the measurement measures the biological information of the person being measured by using the terminal device 100 to photograph the person being measured while checking an image including the person being measured displayed on the screen of the display device. Such a terminal device 100 is used, for example, in a care setting when a caregiver (measurer) measures the biological information of a person being cared for (person being measured).

[0014] The functions of the terminal device 100 described below can also be realized by installing a program on a general-purpose computer. The program can also be called application software. In the following, an example will be described in which the terminal device 100 is a smartphone on which the program is installed.

[0015] The control unit 1 controls each unit of the terminal device 100 in an integrated manner. The photographing device 2 photographs images. The input device 3 accepts input operations to the terminal device 100. The display device 4 displays images photographed by the photographing device 2. The input device 3 may be a touch panel, in which case the input device 3 is configured integrally with the display device 4.

[0016] The communication device 5 transmits and receives various data between an external communication device and the control unit 1. The communication device 5 connects the terminal device 100 and the server 200 via the network N, enabling data exchange between them. The storage device 6 stores various data handled by the terminal device 100. The temperature measurement device 7 detects the body temperature of the person being measured without contact.

[0017] (2. Control Unit) The control unit 1 includes a measurement processing unit 11, an authentication processing unit 12, a display control unit 13, and a temporary storage processing unit .

[0018] The measurement processing unit 11 measures the biological information of the subject based on the captured image of the subject, and transmits the measurement results to the server 200. Specifically, the measurement processing unit 11 measures the biological information of the subject based on the image of the subject captured by the imaging device 2 (hereinafter referred to as the captured image). The measurement processing unit 11 measures the body temperature of the subject based on the captured image captured by the temperature measuring device 7. The measurement processing unit 11 transmits the measurement results of the measured biological information of the subject to the server 200 via the communication device 5. Hereinafter, the measurement results of the biological information may be simply referred to as the measurement results.

[0019] The authentication processing unit 12 transmits authentication information for authenticating the subject to the server 200 and obtains the authentication result from the server 200. Specifically, the authentication processing unit 12 transmits a facial image photograph of the subject taken by the photographing device 2 to the server 200 via the communication device 5. The authentication processing unit 12 obtains the authentication result for the transmitted facial image photograph of the subject.

[0020] The display control unit 13 controls the display device 4 and displays on the display device 4 a measurement standby screen (measurement screen) D1 (see FIG. 2) that accepts measurement operations using the measurement processing unit 11 and authentication processing unit 12. After the measurement operation accepted on the measurement standby screen D1 is completed, the display control unit 13 displays a current measurement result screen (current result screen) D3 (see FIG. 2) that includes the authentication result and measurement result. Furthermore, the display control unit 13 displays at least one status icon P (see FIG. 2) on the measurement standby screen D1, which indicates, in a display format, the measurement status of the measurement operation performed within a predetermined period of time going back from the present time.

[0021] In this embodiment, the display control unit 13 erases the status icon P displayed on the measurement standby screen D1 at least one of the following times: when the terminal device 100 is powered off, when the terminal device 100 is powered on, when a first predetermined period has elapsed since login, and when a second predetermined period has elapsed since manual logout. The display control unit 13 does not erase the status icon P when the terminal device 100 transitions to a sleep state. The display control unit 13 may display the status icon P on the measurement standby screen D1 for a predetermined period in the past, going back from the present time.

[0022] In this embodiment, when an operation to select a status icon P is performed, the display control unit 13 displays a past measurement result screen (past result screen) D4 (see FIG. 5) including the authentication result and measurement result of a past measurement operation in which the selected status icon P indicates the measurement status. The operation to select a status icon P is, for example, an operation to touch the status icon P, and will be referred to as a tap hereinafter. Furthermore, hereinafter, the status icon P will be simply referred to as the icon P unless otherwise specified.

[0023] The current measurement result screen D3 is a measurement result screen that is displayed upon completion of the measurement operation, and the past measurement result screen D4 is a measurement result screen that shows the results of past measurement operations and is displayed by tapping the icon P.

[0024] The temporary storage processing unit 14 temporarily stores the authentication results and measurement results of past measurement operations performed within a predetermined period in the storage device 6. When an operation to select the icon P is performed, the display control unit 13 displays a past measurement result screen D4 using the authentication results and measurement results of past measurement operations temporarily stored in the storage device 6 by the temporary storage processing unit 14.

[0025] The temporary storage processing unit 14 temporarily stores information necessary for displaying the past measurement result screen D4 in the storage device 6. The information necessary for display includes status information indicating the measurement status of the current measurement operation, a screenshot image of the current measurement result screen D3, a photo for facial authentication, a measurement result photo, the measurement result, and the name and ID (identification information) of the person being measured, which are the facial authentication results. Note that it is not necessary to include all of the information listed here. The information stored by the temporary storage processing unit 14 includes personal information that can identify the person, such as the name and facial photo of the person being measured.

[0026] The temporary storage processing unit 14 deletes the stored information at least at one of the following times: when the terminal device 100 is powered off, when the terminal device 100 is powered on, when a first predetermined period has elapsed since login, and when a second predetermined period has elapsed since manual logout. The temporary storage processing unit 14 does not delete the information when the terminal device transitions to a sleep state.

[0027] Although details will be described later, one of the measurement states represented by the icon P is a "communication error" indicating that communication with the server 200 has not been possible. When the measurement state is a "communication error," the display control unit 13 displays a data resend button (retransmit button) 117 (see reference numeral 1007 in FIG. 5) on the past measurement result screen D4, which accepts an instruction to resend the authentication information and measurement results.

[0028] (3. Basic operation of measurement) 2 is a diagram showing, together with screen images, the basic operation of the measurement operation performed using the terminal device 100. When starting measurement, the display control unit 13 displays a measurement standby screen (measurement screen) D1.

[0029] <Measurement standby screen> As shown in FIG. 2, the measurement standby screen D1 displays a frame image 101, an instruction message 102, a staff member name 103, a staff member change button 104, a logout button 105, and the like.

[0030] The frame image 101 indicates the measurement area, and is an area in which the face image of the person being measured is placed. The instruction message 102 is a message indicating instructions for the person taking the measurement. The staff name 103 is the name of the logged-in operator who will be performing the measurement using the terminal device 100. The staff change button 104 accepts a change of operator, and the logout button 105 accepts logout.

[0031] Furthermore, the measurement standby screen D1 displays an icon P. In this embodiment, an icon display area 106 for displaying the icon P is provided in the vicinity of the frame image 101, specifically in the area immediately below the frame image 101.

[0032] When the person taking the measurement moves the terminal device 100 and places the face of the person being measured within the frame image 101, the authentication processing unit 12 and measurement processing unit 11 perform face detection and start their respective processes. The authentication processing unit 12 transmits a facial image, which is a photograph of the face image within the frame image 101, to the server 200 as authentication information, and receives the authentication result transmitted from the server 200. The measurement processing unit 11 measures biometric information based on the face image within the frame image 101, and transmits the measurement result to the server 200.

[0033] <Measurement screen> When face detection by the authentication processing unit 12 and the measurement processing unit 11 begins, the display control unit 13 switches the display from the measurement standby screen D1 to a measurement in progress screen D2. The measurement in progress screen D2 displays a message 107 indicating that measurement is in progress, a facial image 108 of the subject being photographed, and information 109 about the time remaining until the end of measurement. Note that the icon P is not displayed on the measurement in progress screen D2.

[0034] Furthermore, if the face image of the person being measured deviates from the frame image 101 beyond the allowable range during measurement, the measurement processing unit 11 determines that the face has not been detected and stops the measurement, and the display control unit 13 switches the display from the measurement in progress screen D2 to the measurement standby screen D1. When the face image enters the frame image 101 on the switched measurement standby screen D1, the measurement processing unit 11 starts the measurement process again.

[0035] <Current measurement result screen> When the measurement processing unit 11 completes the measurement, the display control unit 13 switches the display from the measurement in progress screen D2 to a current measurement result screen D3. The current measurement result screen D3 displays authentication result information 111 received from the server 200, a facial image 112 of the subject, comparison result information 113 received from the server 200, measurement value information 114, a button 115 to return to the measurement screen, etc.

[0036] If authentication is successful, the authentication result information 111 contains information such as the name and ID of the person being measured, and if authentication is not successful, it contains information informing the person that authentication was not successful (see reference numeral 1006 in FIG. 5). If communication with the server 200 is not possible, information 116 informing the person that communication was not possible is displayed instead of the authentication result information 111 (see reference numeral 1007 in FIG. 5).

[0037] As the face image 112 of the subject, the face image of the subject that the authentication processing unit 12 has transmitted to the server 200 as authentication information is used.

[0038] The comparison result information 113 is the result of the server 200 comparing the current measurement result with past measurement results. In the example of Fig. 2, "Active level: similar level to previous" is displayed as the comparison result information 113, indicating that the level of the current measurement value is the same as the level of the previous measurement value. If the level of the current measurement value has changed from the level of the previous measurement value, "Active level: changed from previous level" is displayed as the comparison result information 113 (see reference numeral 1008 in Fig. 5).

[0039] Measurement value information 114 is information about the measurement value obtained in the current measurement. A button 115 to measurement screen and the like accepts an operation to display the measurement standby screen D1.

[0040] The current measurement result screen D3 also displays information about the date and time when the measurement operation was performed, such as "2023 / 8 / 31 14:35:59." Note that instead of displaying the time, it may also display "Identity confirmed and recorded," which indicates the result of identity verification. In this case, the information about the date and time when the measurement operation was performed may or may not be displayed depending on the display space.

[0041] (4. Status icon) Fig. 3 is an explanatory diagram of status icons P that indicate the operation status of past measurement operations and are displayed on the measurement standby screen D1. As shown in Fig. 3, the measurement standby screen D1 is provided with an icon display area 106, which can display up to a predetermined number of icons P. In the example of Fig. 3, up to a total of seven icons P can be displayed.

[0042] <Measurement status> As described above, the icon P is an icon that represents, in a display form, the measurement status of the measurement operation performed within a predetermined period of time going back from the present time. Items 1) to 5) correspond to status information.

[0043] In this embodiment, the measurement states represented by the icon P include the following five states. 1) Measurement completed successfully: There is no change exceeding the specified value between the current measurement result and the previous measurement result. 2) Change from previous measurement: A state in which there has been a change exceeding a specified value between the current measurement result and the previous measurement result. 3) Re-measurement: A state in which the measurement operation needs to be redone. 4) Communication error: Communication with server 200 was not possible. 5) Authentication error: A state in which the authentication result does not allow the subject to be authenticated.

[0044] In this embodiment, the measurement status represented by the icon P is exemplified as including all of 1) to 5), but it is sufficient if it includes at least one of 1) to 5).More specifically, the remeasurement in 3) is a state where there is a problem with the brightness at the time of measurement, resulting in a problem with the measurement accuracy, and the authentication error in 5) is a state where the person could not be confirmed as a registered person through face authentication.

[0045] <Differences in display format> In this embodiment, the display control unit 13 indicates such differences in measurement state by changing the display color of the icon P depending on the measurement state.

[0046] A specific example will be described. In this embodiment, the display control unit 13 sets the shape of the icons P to be the same, which is a circle (circle shape) in this case. Note that the common shape of the icons P is not limited to a circle, and may be a square (square shape), a triangle (▽ or △ shape), a star shape (☆ shape), etc.

[0047] For example, as shown below, the display control unit 13 associates the measurement states 1) to 5) with the display colors of the icon P. Note that the relationship between the measurement states and the display colors is merely an example. 1) "Measurement completed successfully" status above: Green icon P(G). 2) "Changed from last time" status: Blue icon P(B). "Remeasurement" status in 3) above: Yellow icon P(Y). "Communication error" status (4) above): Red icon P(R). "Authentication error" status (5) above): Light brown icon P(C).

[0048] In the example of the measurement standby screen D1 shown in Figure 3, five icons are displayed from the left: icon P(G), icon P(Y), light brown icon P(C), red icon P(R), and blue icon P(B).

[0049] The icon P may be configured so that the shape of the icon changes depending on the measurement state, but in terms of making effective use of the limited screen area, it is more efficient to display it using the free space in the measurement standby screen D1. Therefore, as described above, the configuration in which the shape of the icon P remains the same but the display color changes does not require specifying the shape, so it is easy to see even if it is extremely small.

[0050] Hereafter, when it is necessary to distinguish the icons P in correspondence with the measurement state, the icons P(G), P(B), P(Y), P(R), and P(C) containing color information are used, and when there is no need to distinguish, the icon P is used.

[0051] Furthermore, in this embodiment, the display control unit 13 displays a plurality of icons P so that the measurement order can be seen, tracing back from the most recent measurement operation to the past.

[0052] 3, the display control unit 13 displays the icon P of the most recent measurement operation at the left end of the icon display area 106. Each time a measurement operation is performed, the display control unit 13 shifts the icon P that has already been displayed to the right and displays the icon P of the most recent measurement operation at the left end.

[0053] 3, a total of seven icons P can be displayed in the icon display area 106, and five measurement operations have been performed, including the most recent measurement operation. The two dotted circles that resemble the shape of the icon P on the far right indicate an empty state. In other words, this indicates that a total of five measurement operations have been performed within a predetermined period of time going back from the present time.

[0054] Additionally, the most recent measurement operation is a green icon P(G), indicating that the measurement was completed successfully, the measurement operation one operation before the most recent one is a yellow icon P(Y), indicating that remeasurement was required, the measurement operation two operations before the most recent one is a light brown icon P(C), indicating that there was a facial recognition error, the measurement operation three operations before the most recent one is a red icon P(R), indicating that there was a communication error, and the measurement operation four operations before the most recent one is a blue icon P(B), indicating that there was a change from the previous operation.

[0055] In this way, by displaying the icons P so that the measurement order is clear, the person taking the measurement can identify subjects who need to be remeasured or who need to be resent from the order of the displayed icons P, as long as they remember the order in which the subjects were measured.

[0056] <Additional information on status icons> Furthermore, the display control unit 13 may display the icon P including at least one of a symbol indicating the measurement order, ID information indicating the corresponding person to be measured, and information indicating the gender.

[0057] As shown in Fig. 3, in this embodiment, the display control unit 13 displays numbers as symbols indicating the measurement order as additional information inside the circle of the icon P. In the example of Fig. 3, the number "1" indicating that this is the first measurement operation is displayed inside the circle of the blue icon P(B) that was performed first after the power was turned on. The numbers indicating the measurement order increase from "1, 2, 3, 4, 5" toward the left, and the green icon P(G) on the far left with the number "5" indicates that it is the icon P for the most recent measurement operation. "1, 2, 3, 4, 5, ..." correspond to the serial numbers from the start of measurement when the power was turned on.

[0058] Fig. 4 is a diagram showing examples of icons having additional information. As indicated by reference numeral 1001 in Fig. 4, the additional information may be the ID (identification information) of the person being measured in the measurement operation in which each icon P indicates the measurement status. Alternatively, as indicated by reference numeral 1002, the additional information may be information indicating the gender of the person being measured, such as F (female) or M (male), in the measurement operation in which each icon P indicates the measurement status. Alternatively, as indicated by reference numeral 1003, the additional information may be information on the time when the measurement operation in which each icon P indicates the measurement status was performed.

[0059] In short, the additional information should be information that allows the person viewing the icon P to more specifically understand which measurement operation performed in the past was the measurement state indicated by the icon P, in addition to the measurement state represented by the color of the icon P.

[0060] In this way, by displaying the icons P together with additional information, the person taking the measurement can ascertain the order of measurements, the ID of the person being measured, or the gender of the person being measured from the additional information. Therefore, even if the person does not clearly remember the order in which the people being measured were measured, the additional information can provide a hint for matching the people being measured with the icons P by searching their memory, making it easier to identify people who need to be measured again or who need to be resent.

[0061] (5.Past measurement results screen) Fig. 5 is a diagram showing a past measurement result screen D4 that is displayed by tapping icon P displayed on the measurement standby screen D1 shown in Fig. 3. The screen configuration is generally the same as the current measurement result screen D3 shown in Fig. 2. That is, it displays a facial image 112 of the subject, authentication result information 111, comparison result information 113, measurement value information 114, etc.

[0062] The difference is that the past measurement result screen D4 includes an icon image PP of the icon P that represents the measurement status, which is not displayed on the current measurement result screen D3. By displaying such an icon image PP, the measurement status of the past measurement result screen D4 can be intuitively known without having to check the display content of the past measurement result screen D4. The icon image PP may include an image of additional information for the icon P.

[0063] Reference numeral 1004 denotes a past measurement result screen D4 when the measurement has ended normally, which is displayed by tapping the green icon P(G). An image PP(G) of the green icon P(G), which indicates that the measurement has ended normally, is displayed to the left of the display area of ​​the authentication result information 111.

[0064] Reference numeral 1005 denotes a past measurement result screen D4 when remeasurement is required, which is displayed by tapping the yellow icon P(Y). Because the brightness at the time of measurement was outside the specified range, the accuracy of the measurement value is determined to be low, and information urging the user to remeasure "! Brightness" is displayed to the left of the display area for the measurement value information 114. An image PP(Y) of the yellow icon P(Y), indicating that remeasurement is required, is displayed to the left of the display area for the authentication result information 111.

[0065] Note that remeasurement may be required not only when the brightness deviates from the predetermined range. For example, there may be a malfunction of the temperature measuring device 7 (such as a communication error with the temperature measuring device 7, a disconnection, or damage), blood vessel information when blood vessel information cannot be estimated from an image of the subject (when an error occurs from the measurement processing unit 11), or heart rate information when heart rate information cannot be estimated from an image of the subject (when an error occurs from the measurement processing unit 11). In these cases, the letter "E" indicating an error may be displayed in the column displaying the measured value.

[0066] Reference numeral 1006 denotes a past measurement result screen D4 displayed by tapping the light brown icon P(C) when face authentication has resulted in an error. Information "Not registered as subject" is displayed as authentication result information 111, informing users that authentication has failed. Furthermore, information 119 "This data cannot be sent" is displayed instead of comparison result information 113. An image PP(C) of the light brown icon P(C), indicating that face authentication has resulted in an error, is displayed to the left of the display area of ​​the authentication result information 111.

[0067] Reference numeral 1007 denotes a past measurement result screen D4 in the event of a communication error, which is displayed by tapping the red icon P(R). Instead of the authentication result information 111, "Communication Unable" information 116 is displayed, notifying that communication with the server 200 was not possible. Also, instead of the comparison result information 113, a data resend button 117 is displayed, which accepts an instruction to resend the authentication information and measurement results. An image PP(R) of the red icon P(R), indicating that a communication error occurred, is displayed to the left of the display area of ​​the authentication result information 111.

[0068] Reference numeral 1008 denotes a past measurement result screen D4 that is displayed by tapping the blue icon P(B), and shows a change in the measurement value level from the previous time. An image PP(B) of the blue icon P(B), which indicates that the measurement value level has changed from the previous time, is displayed to the left of the display area for the authentication result information 111.

[0069] The display control unit 13 may create and display such a past measurement result screen D4 when the icon P is tapped, or may take a screenshot of the current measurement result screen D3 displayed during a past measurement operation, save it as an image file, and display it using the image file. In this case, however, the icon image PP is not included in the past measurement result screen D4.

[0070] Fig. 6 is a diagram showing the screen transition when the data resend button 117 is tapped on the past measurement result screen D4 in the event of a communication error. As indicated by reference numeral 1010 in Fig. 6, the data resend button 117 is displayed on the past measurement result screen D4 in the event of a communication error. By tapping this data resend button 117, it is possible to instruct the resend of authentication information and measurement results.

[0071] When the data resend button 117 is tapped, the authentication processing unit 12 and the measurement processing unit 11 transmit the face image of the subject and the measurement results, which are authentication information temporarily stored in the storage device 6, to the server 200. When resend is started, the display control unit 13 displays a resend screen D5 indicating that resend is in progress.

[0072] When retransmission of the authentication information and measurement results is complete, the display control unit 13 switches from the retransmission screen D5 to an updated past measurement result screen D4 for when the measurement has ended normally, as indicated by reference numeral 1011. When the measurement screen button 115 is tapped on the past measurement result screen D4 indicated by reference numeral 1011, the display control unit 13 displays a measurement standby screen D1 in which the operation status of the past measurement operation has been updated, as indicated by reference numeral 1012.

[0073] As can be seen by comparing with the measurement standby screen D1 shown in Figure 2, in the measurement standby screen D1 shown by the reference numeral 1012, the icon P displaying "2" as additional information has been updated from a red icon P(R) indicating a communication error state to a green icon P(G) indicating a normal measurement completion state.

[0074] In this way, if the status of the past measurement operation is a communication error, the authentication information and measurement results can be resent from the past measurement result screen, so there is no need to measure again, and the measurement work can be made more efficient.

[0075] (6. Sequence) <Basic operation> Fig. 7 is a diagram showing the sequence of basic operations of a measurement operation performed using the terminal device 100. As shown in Fig. 7, the person performing the measurement performs the measurement operation (S1) using the terminal device 100. That is, the person performing the measurement causes the terminal device 100 to display a measurement standby screen D1, and captures an image of the face of the person being measured.

[0076] The terminal device 100 transmits a face authentication photograph as authentication information to the server 200 (S2). The server 200 performs face authentication based on the received face authentication photograph, and transmits a face authentication result, which is the authentication result, to the terminal device 100 (S3).

[0077] The terminal device 100 transmits the measurement results to the server 200 (S4). The server 200 compares the received measurement results with past measurement results of the subject and transmits the comparison results to the terminal device 100 (S5).

[0078] The terminal device 100 temporarily stores information necessary for displaying the past measurement result screen D4 in the storage device 6 (S6). The information necessary for display includes a screenshot image of the current measurement result screen D3, a photo for face authentication, a measurement result photo, the measurement result, the name of the person being measured, the ID of the person being measured, and status information indicating the measurement status of the current measurement operation.

[0079] It is not necessary to temporarily store all of the information listed here, and it is sufficient to store enough information to display a past measurement result screen D4 equivalent to the current measurement result screen D3 or similar to the current measurement result screen D3. In other words, if the person being measured can identify the person being measured by their name, it is not necessary to store a face authentication photo for displaying the facial image 112. Similarly, if the person being measured can identify the person being measured by their facial photo, it is not necessary to store information such as the person's name and ID.

[0080] Furthermore, when the terminal device 100 receives the face authentication result and comparison result from the server 200, it displays a current measurement result screen D3 (S7). When the button 115 is tapped on the measurement screen, the terminal device 100 closes the current measurement result screen D3 and displays a measurement standby screen D1. On the measurement standby screen D1 displayed here, the measurement status of the measurement operation on the current measurement result screen D3 displayed in S7 is displayed as an icon P of the most recent constant operation at the left end of the icon display area 106 (see FIGS. 2 and 3).

[0081] If the measurer wishes to display the current measurement result screen D3 that has been temporarily closed, the measurer taps the icon P that the measurer wishes to redisplay from among the icons P displayed on the measurement standby screen D1 (S8: request redisplay).

[0082] The terminal device 100 displays a past measurement result screen D4 of the measurement operation in which the tapped icon P indicates the measurement state (S9). The example in Fig. 7 shows the past measurement result screen D4 when the icon P of the most recent measurement operation displayed in S7 is tapped.

[0083] <Operation when a communication error occurs> Fig. 8 is a diagram showing the sequence of operations when a communication error occurs during measurement operations performed using the terminal device 100. As shown in Fig. 8, when a communication error occurs, the processes of S2 to S5 cannot be executed. The terminal device 100 temporarily stores the face authentication photograph and measurement results that could not be transmitted to the server 200 in the storage device 6 (S11).

[0084] The terminal device 100 displays a current measurement result screen D3 including a message informing the user that communication has failed (S7). If communication has failed, the subject cannot be authenticated, and therefore the authentication result information 111 and the comparison result information 113 are not displayed on the current measurement result screen D3.

[0085] When button 115 is tapped on the measurement screen, terminal device 100 closes current measurement result screen D3 and displays measurement standby screen D1. On measurement standby screen D1 displayed here, the measurement status of the measurement operation on current measurement result screen D3 displayed in S7 is displayed as icon P of the most recent measurement operation at the left end of icon display area 106 (see FIGS. 2 and 3).

[0086] When the communication environment improves, for example by moving to another room, the person measuring taps icon P(R), which indicates a communication error state, from among the icons P displayed on the measurement standby screen D1 (S8: Request redisplay).

[0087] The terminal device 100 displays the past measurement result screen D4 of the measurement operation, on which the tapped icon P indicates the measurement status, based on the information temporarily saved in S11 (S9). The person taps the data resend button 117 displayed on the past measurement result screen D4 (S12: resend request). As a result, the processes of S2 to S5 are executed between the terminal device 100 and the server 200.

[0088] The terminal device 100 additionally stores the information received from the server 200 that could not be saved in S11, such as the name of the person being measured, the ID of the person being measured, and the comparison results, and updates the status information of the corresponding past measurement operation from a communication error status (S13).

[0089] The terminal device 100 updates the past measurement result screen D4 using the information additionally saved in S16 and the updated status information (S14). The example in Fig. 8 shows a case where the past measurement result screen D4 showing a communication error displayed in S9 has been updated to a past measurement result screen D4 showing normal measurement completion.

[0090] (7. Description of Effects) In the above configuration, an icon P representing the past measurement status in a display format is displayed on the measurement standby screen D1, so the person taking the measurement can check the measurement status of past measurement operations from the measurement standby screen D1 during the measurement work. For example, when measuring the biological information of person A, it is possible to check the measurement status of person B, who measured the biological information using the terminal device 100 before person A. Therefore, if the measurement status of person B displayed by icon P indicates that remeasurement is necessary, the person taking the measurement can decide the next action based on the past measurement status while taking the measurement work of person A. This makes it possible to achieve an efficient measurement work.

[0091] Furthermore, in the above configuration, by tapping icon P displayed on measurement standby screen D1, it is possible to display past measurement result screen D4, on which icon P indicates the measurement status. This makes it possible to easily view authentication results and measurement results from past measurement operations by switching screens in response to instructions from measurement standby screen D1, thereby realizing more efficient measurement work.

[0092] In addition, the temporary storage processing unit 14 temporarily stores the authentication results and measurement results from past measurement operations in the terminal device and deletes them at a predetermined timing. Therefore, proper handling of personal information can be ensured without impairing the convenience of being able to display the past measurement result screen D4, in which the icon P indicates the measurement status, by tapping the icon P.

[0093] (Variation) Incidentally, in the terminal device 100 of embodiment 1, the current measurement result screen D3 (see Figure 2) does not display the icon image PP of the icon P representing the measurement status, but the current measurement result screen D3 may also display the icon image PP indicating the measurement status.

[0094] In this way, the icon image PP is displayed not only on the past measurement result screen D4 but also on the current measurement result screen D3, so that the measurement status of the current measurement operation can be intuitively known from the icon image PP included in the current measurement result screen D3.

[0095] With this configuration, the icon image PP on the current measurement result screen D3 showing the current measurement result, the icon P displayed on the measurement standby screen D1, and the icon image PP on the past measurement result screen D4 all match, allowing the person taking the measurement to more easily understand the measurement status.

[0096] Fig. 9 is a diagram showing the sequence of basic operations of a measurement operation performed using the modified terminal device 100. As shown in Fig. 9, the modified terminal device 100 also displays the measurement status of the current measurement, including an icon image PP of a status icon P.

[0097] If the current measurement result is displayed on the measurement standby screen D1 that is displayed next with the icon P including "5" indicating that the measurement is the fifth in the order, the icon image PP may also include "5."

[0098] Furthermore, by including the icon image PP on the current measurement result screen D3, in S6, it becomes possible to take a screenshot of the current measurement result screen D3 and save it as an image file, and then use the saved image file to display the past measurement result screen D4.

[0099] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0100] In the terminal device 100 of the first embodiment, the temporary storage processing unit 14 temporarily stores information necessary for displaying the past measurement result screen D4 in the storage device 6. Of the information stored in the terminal device 100, the screenshot image of the current measurement result screen D3, the photograph for face authentication, and the name of the person being measured are personal information that can identify a specific individual based on that information.

[0101] Explained with reference to Fig. 1, the terminal device 100A of this embodiment differs in that it includes a control unit 1A instead of the control unit 1. By including the control unit 1A, the terminal device 100A of this embodiment does not store any personal information within the terminal device 100A, and allows the subject to understand only the operational status of past measurement operations by displaying an icon P' on the measurement standby screen D1.

[0102] Specifically, in the control unit 1A, the temporary storage processing unit 14 temporarily stores only information that does not correspond to personal information such as the subject's ID, along with the status information of the measurement operation, in association with the measurement operation. Note that if information indicating gender, age, or the like is acquired as authentication result information, this information may also be stored in association with the measurement operation.

[0103] In the terminal device 100A, the display control unit 13 displays an icon P' on the measurement standby screen D1 using the state information stored in the terminal device 100A. In the terminal device 100A, even if the icon P' is tapped, the past measurement result screen D4 is not displayed.

[0104] Fig. 10 is a diagram showing the sequence of basic operations of a measurement operation performed using a terminal device 100A according to embodiment 2 of the present invention. As shown in Fig. 10, the processes of S1 to S5 and S7 are the same as the processes of S1 to S5 and S7 in Fig. 7. The terminal device 100A stores in the storage device 6 the ID of the person being measured that does not correspond to personal information and status information indicating the measurement status of the current measurement operation, among the information required to display the current measurement result screen D3 (S20). Fig. 10 shows the sequence in a configuration in which an icon image PP is also displayed on the current measurement result screen D3, as described as the terminal device 100 of the modified embodiment in embodiment 1.

[0105] When button 115 is tapped on the measurement screen of current measurement result screen D3, terminal device 100A closes current measurement result screen D3 and displays measurement standby screen D1. On measurement standby screen D1 displayed here, the measurement status of the measurement operation on current measurement result screen D3 displayed in S7 is displayed as icon P' of the most recent measurement operation at the left end of icon display area 106 (see FIGS. 2 and 3).

[0106] (Description of effects) In the above configuration, the past measurement result screen D4 is not displayed, but the status icon P is displayed on the measurement standby screen D1, so the person taking the measurement can understand the status of past measurement operations based on the arrangement of the icons P'. Since no personal information of the person being measured is left in the terminal device 100A, this is even more excellent in terms of appropriate handling of personal information.

[0107] In particular, in a configuration in which the operation status is simply displayed using such an icon P', additional information such as the subject's ID, gender information, and age information can be included inside the icon P', which helps the person taking the measurement to associate the previous measurement operations with the subject, allowing them to understand whether or not re-measurement is necessary, and work efficiently.

[0108] In this embodiment, the temporary storage processing unit 14 is not configured to store personal information in the storage device 6, so there is no need to delete the stored information at the timing described above.

[0109] [Embodiment 3] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0110] Fig. 11 is a block diagram showing a schematic configuration of a terminal device 100B according to a third embodiment of the present invention. As shown in Fig. 11, a control unit 1B is provided instead of the control unit 1. The control unit 1B includes an information acquisition unit 15. The terminal device 100B of this embodiment does not store personal information within the terminal device 100B, and displays a past measurement result screen D4.

[0111] The temporary storage processing unit 14 temporarily stores the ID (identification information) of the person being measured, which is included in the authentication result of a previous measurement operation performed within a predetermined period of time, together with status information indicating the measurement status. The display control unit 13 uses the status information stored in the terminal device 100B to display an icon P on the measurement standby screen D1.

[0112] When icon P is tapped, information acquisition unit 15 transmits to server 200 the ID included in the authentication result of the past measurement operation for which the tapped icon P indicates the measurement state, and acquires the measurement result and authentication result associated with the ID from the server. When icon P is tapped, display control unit 13 displays a past measurement result screen D4 including the measurement result and authentication result acquired by information acquisition unit 15.

[0113] Furthermore, the temporary storage processing unit 14 also temporarily stores the measurement results if communication with the server 200 is not possible. This is because the measurement results can be retransmitted from the past measurement result screen D4 in the event of a communication error.

[0114] Fig. 12 is a diagram showing the sequence of the basic operation of the measurement operation performed using the terminal device 100B. As shown in Fig. 12, the processes of S1 to S5 and S7 are the same as the processes of S1 to S5 and S7 in Fig. 7. Fig. 12 also shows the sequence in a configuration in which the icon image PP is also displayed on the current measurement result screen D3, as described as the terminal device 100 of the modified example in the first embodiment.

[0115] The terminal device 100B stores in the storage device 6 the ID information and status information indicating the measurement status of the current measurement operation out of the information on the name and ID of the subject, which is the face authentication result received from the server 200 (S22). As described above, if the status information indicates a communication error, the measurement result is also stored in preparation for retransmission.

[0116] When button 115 is tapped on the measurement screen of current measurement result screen D3, terminal device 100B closes current measurement result screen D3 and displays measurement standby screen D1. On measurement standby screen D1 displayed here, the measurement status of the measurement operation on current measurement result screen D3 displayed in S7 is displayed as icon P of the most recent measurement operation at the left end of icon display area 106 (see FIGS. 2 and 3).

[0117] If the measurer wishes to display the current measurement result screen D3 that has been temporarily closed, the measurer taps the icon P that the measurer wishes to redisplay from among the icons P displayed on the measurement standby screen D1 (S8: request redisplay).

[0118] When the icon P is tapped, the terminal device 100B transmits to the server 200 the ID included in the authentication result of the previous measurement operation in which the tapped icon P indicates the measurement state (S23). Note that if the measurement state is a communication error, the measurement result is also transmitted.

[0119] The server 200 transmits the name of the person being measured identified by the received ID, the measurement result, and the comparison result to the terminal device 100B (S24). Note that if the measurement status is a communication error, the measurement result does not need to be transmitted because it is stored in the terminal device 100B.

[0120] The terminal device 100B uses the information acquired in S24 to display a past measurement result screen D4 of the measurement operation in which the icon P tapped in S8 indicates the measurement state (S25). As shown in Fig. 11, the face image 112 of the person being measured, which is personal information, is not saved, and therefore the face image 112 is not displayed on the past measurement result screen D4.

[0121] (Description of effects) According to this, by tapping the status icon, the necessary information can be received from the server 200 and past measurement results in which the status icon indicates the measurement status can be displayed. Since no personal information of the subject is left in the terminal device 100B, it is even more excellent in terms of appropriate handling of personal information.

[0122] In this embodiment, the temporary storage processing unit 14 is not configured to store personal information in the storage device 6, so there is no need to delete the stored information at the timing described above.

[0123] [Embodiment 4] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0124] 1 and 11, the terminal device 100C of this embodiment differs from the terminal devices 100, 100B of embodiments 1 and 3 in that it includes a control unit 1C instead of the control units 1, 1B. By including the control unit 1C, the terminal device 100C of this embodiment also displays an icon P on the past measurement result screen D4, and by tapping the icon P, it is possible to transition from the past measurement result screen D4 to another past measurement result screen D4.

[0125] That is, in the terminal device 100C of this embodiment, the display control unit 13 also displays on the past measurement result screen D an icon P that displays the corresponding past measurement result screen D4 when tapped.

[0126] Fig. 13 is a diagram showing the operation of displaying a past measurement result screen in the terminal device 100C according to embodiment 4 of the present invention. As shown in Fig. 13, when an icon P is tapped on the measurement standby screen D1, the display control unit 13 displays a past measurement result screen D4, which is a measurement result screen of a past measurement operation in which the tapped icon P indicates the measurement state.

[0127] The past measurement result screen D4C displays an icon P for accepting a display instruction for the past measurement result screen D4, in addition to the display contents of the past measurement result screen D4 displayed in the terminal devices 100 and 100B of embodiments 1 and 2. In the example of Fig. 13, the icon P is displayed between the comparison result information 113 and the measurement value information 114.

[0128] When an icon P is tapped on the past measurement result screen D4C, the display control unit 13 displays the past measurement result screen D4C in which the tapped icon P indicates the measurement state.

[0129] 14 is a diagram showing a past measurement result screen D4C including an icon P displayed on the terminal device 100C. The screen configuration is generally the same as the past measurement result screen D4 shown in FIG. 5 in the first embodiment. The difference is that an icon P is displayed that can be tapped to transition to another past measurement result screen D4C. By displaying such an icon P on the past measurement result screen D4C as well, past measurement results can be checked consecutively, enabling more efficient measurement work.

[0130] [Software implementation example] The functions of terminal devices 100, 100A, 100B, and 100C (hereinafter referred to as "devices") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in control units 1, 1A, 1B, and 1C).

[0131] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program.
