Description

The present invention relates to an attendance management program, an attendance management device, and an attendance management method.

Attendance of students and students (hereinafter simply referred to as students) is confirmed in school classrooms and lecture venues (hereinafter simply referred to as classrooms). In such school classes and lectures (hereinafter simply referred to as lectures), credits are not granted to students who do not achieve the attendance rate above the prescribed level. Therefore, it is necessary to manage attendance only for students who attended lectures held in the classroom and not for students who did not attend.

Student attendance management is described in the following patent documents.

JP-A-2017-194854 Japanese Unexamined Patent Publication No. 2016-167281 Japanese Patent No. 5919438

As a general attendance confirmation, there is a method of pre-distributing the attendance card to the students and having the terminal device of the classroom read the attendance card information. However, such a method requires the issuance of attendance cards, an information reading device, and the like, and further, it is easily possible for one student to collectively perform attendance operations for a plurality of student attendance cards.

In recent years, attendance management systems that use smartphones to confirm that students are coming to lectures in the classroom have become widespread. In such an attendance management system, the student's smartphone sends an attendance email to the server along with the location information, and the server confirms that the student is coming to the lecture in the classroom based on the location information of the received attendance email.

However, the accuracy of the position information acquired by the smartphone differs depending on the terminal or the like, and the accuracy of attendance confirmation may not be high. In addition, the location information of smartphones may not be recommended to students from the viewpoint of protecting personal information.

It has also been proposed that instead of acquiring location information, a teacher moves around the classroom with a beacon device, a smartphone receives a beacon wave, and an attendance email is sent to a server together with the beacon wave signal. However, teachers need to bring beacon equipment.

Therefore, an object of the first aspect of the present embodiment is to provide an attendance management program, an attendance management device, and an attendance management method that can confirm attendance by a simple method and that is difficult to cheat. ..

The first aspect of the present embodiment is to generate a code image animation in which the code of the character string is sequentially changed and a plurality of code images associated with the generated plurality of codes are sequentially displayed.

[First Embodiment]
FIG. 1 is a diagram showing a configuration example of an attendance management system according to the present embodiment. The attendance management system includes an attendance management server 10, a teacher's terminal device 32 and a display device 34 in a classroom or a classroom 30 which is a lecture hall, and terminal devices 36_1 and 36_2 of a plurality of students. The attendance management server 10 can communicate with the teacher terminal device 32 and the student terminal device 36 via the network NW.

The attendance management server 10 is, for example, a computer, and has a processor 12, a main memory 14, an input / output device 16, a network interface 18, a bus 19, and large-capacity auxiliary storage devices 20, 22, 24 such as HDDs and SSDs. The auxiliary storage device stores an attendance management program 20 for confirming attendance, a code generation program 22, and user data 24 for storing student information.

The teacher terminal device 32 is, for example, a personal computer or a tablet terminal which has a processor, communication means, and display means, and an attendance management application for teachers is installed. Further, the display device 34 is a large-screen monitor device, a projector and a display screen, a tablet terminal arranged in a student's seat and circulated among students, and the like. The student terminal device 36 is a smartphone or tablet terminal that has an imaging means and a communication means and is installed with an attendance management application for students.

FIG. 2 is a sequence diagram showing the attendance confirmation process by the attendance management system. In FIG. 2, the attendance management server 10, the teacher terminal device 32, the display device 34 displaying the image generated by the teacher terminal device, and the attendance management server 10 shown in the horizontal direction with the time axis associated with each other from top to bottom. The processing of each of the student terminal devices 36_1 and 36_1 is shown.

In the attendance management system, attendance is confirmed when the student terminal device 36 performs a process that can be performed only when the student attends a lecture in the classroom. This attendance management system does not require special equipment or equipment and enables attendance confirmation that is difficult to fraudulent. Further, in the attendance management system, it is not necessary to have the student terminal device transmit the location information, and the teacher does not need to bring the beacon into the classroom.

Roughly speaking, the attendance management server 10 generates the character string code while sequentially changing it, and transmits it to the teacher terminal device 32. Then, the teacher terminal device 32 generates a plurality of images (hereinafter referred to as code images) corresponding to the received plurality of codes, generates a code image animation in which the code image changes sequentially, and displays the code image on the display device 34. To do.

While the code image animation is being displayed, a student attending a classroom lecture operates the student terminal device 36 to capture the code image animation, and the student terminal device 36 captures the code data corresponding to the captured code image. It is transmitted to the attendance management server 10. Then, at least one determination target code or the plurality of determination target codes of the plurality of code information received by the attendance management server 10 is one of the plurality of codes generated within the threshold time before the reception time of the determination target code. If it matches one or more criteria codes, the student attendance of the student terminal device is confirmed.

Hereinafter, the above attendance confirmation process will be described with reference to FIG. Further, corresponding to the description of the attendance confirmation process, the process of the teacher terminal device of FIGS. 3 and 4, the process of the attendance management server of FIG. 5, and the process of the student terminal device of FIGS. 6 and 7 will also be described.

An attendance management application for teachers is installed in the teacher terminal device 32, and the teacher activates the attendance management application. Then, when the teacher operates the attendance card issuance request on the teacher terminal device 32, the teacher terminal device transmits the attendance card issuance request to the attendance management server 10 (S1_1), and the teacher further uses the teacher terminal device (attendance). When the operation of the code image animation display request (corresponding to the card) is performed, the teacher terminal device transmits the code image animation display request to the attendance management server 10 (S1_2).

FIG. 3 is a diagram showing a flowchart of processing of the attendance management application for teachers. Further, FIG. 4 is a diagram showing an example of a user interface screen of the terminal device 32 for teachers. The processor of the teacher terminal device 32 executes an attendance management application for teachers and performs an attendance confirmation process.

The processing of the attendance card issuance request and the code image animation display request by the teacher terminal device 32 is as follows. First, when the teacher inputs the user ID and password on the login screen U1 of FIG. 4 and the login authentication by the attendance management server 10 is successful (YES in S10), the teacher terminal device 32 displays the lecture selection screen U2 (). S11). Then, when the teacher selects one of the lectures, for example, lecture A from the lecture list (YES in S12), the teacher terminal device displays the attendance card issuing screen U3 (S13). When the teacher operates the attendance card issuance button 40 on the screen U3 (YES in S14), the teacher terminal device displays the attendance card issuance setting screen U4 returned from the attendance management server.

On this setting screen U4, the teacher selects "attendance (animation)" to use animation, inputs the label (name) "lecture on 19/02/20" of the attendance card to be issued, and the date and time "19 / Set to enter "02/20 13:30" (S15). Then, when the teacher operates the "issue" button 41 (YES in S1_1 and S16), the teacher terminal device sends a card issuance request to the attendance management server. The attendance card issuance request includes the lecture ID, teacher ID, attendance card label information, and attendance card issuance date / time information.

In response to the reply to the card issuance request from the attendance management server, the teacher terminal device 32 displays the image 42 of the attendance card being accepted for "lecture A" as shown in the attendance card display screen U5. The image of the attendance card 42 includes the display 43 of the attendance card management number "9", the animation display request button "animation display" 44, and the label "19/02/20 lecture" entered on the setting screen. Is done. The teacher performs the operations for issuing the attendance card up to this point before or during the lecture.

Next, when the teacher operates the animation display request button "animation display" 44 (YES in S17), the teacher terminal device 32 transmits the animation display request to the attendance management server 10 (S1_2, S18).

Returning to FIG. 2, the attendance management server 10 responds to the attendance card display request from the teacher terminal device 32, generates a character string code while sequentially changing it, and transmits it to the teacher terminal device 32 (S2).

FIG. 5 is a diagram showing a flowchart of processing by the attendance management program of the attendance management server 10. The processor of the attendance management server 10 executes the attendance management program and executes the following processing. First, when the attendance management server receives the code image animation display request of the attendance card from the teacher terminal device 32 (YES in S21), it generates a plurality of random codes at regular intervals (S22), and the generated plurality of codes. Is transmitted to the teacher terminal device 32 at regular intervals (S23).

The fixed time, which is the interval for generating each of the above-mentioned codes, is, for example, 2 seconds. Time intervals other than 2 seconds may be used. Further, the time interval may change randomly instead of a fixed time. This time interval is set to the optimum time interval for the determination process of whether or not the code data received within the threshold time from the code generation time matches the generated code, which is determined by the attendance management server in the attendance confirmation. For example, the time interval is longer than the time during which the image sensor of the student terminal device can capture a code image that changes sequentially. It also has at least a sufficient length for the student to recognize that the code image changes sequentially.

Further, it is desirable that the random series of codes issued in the code image animation display request is unique in the code image animation. As will be described later, if the code image and its code are repeatedly displayed in the code image animation within a short time, the same code image will be included in the code image animation captured by the student terminal device, and the attendance management server This is because there is a possibility that the attendance confirmation determination as to whether or not the generated code and the received code within the threshold time according to the above match will be hindered.

After generating multiple codes, the attendance management server stores the history of multiple codes (S24).

FIG. 9 is a diagram showing an example of the code history recorded by the attendance management server. The code data recorded as the code history has the teacher ID, the lecture code, the attendance card management number (attendance card ID), the code generation number indicating the code generation order, the generation time of each code, and the code itself. ..

Next, as shown in FIG. 2, the teacher terminal device 32 generates a plurality of code images corresponding to each of the plurality of sequentially changing codes transmitted, generates an animation in which the code images change sequentially, and displays the display device. It is displayed on 34 (S3, S4).

A code image animation is a kind of video in which a plurality of different code images change at predetermined time intervals, and corresponds to an attendance card in which a teacher once circulated a student in a classroom to enter the student's name.

The display device 34 is a large screen fixedly installed in the classroom. Alternatively, the display device 34 is a screen of a plurality of tablet terminals that are sequentially circulated at the student's seat in the classroom.

As shown in FIG. 3, when the teacher terminal device 32 continuously receives a plurality of codes that change sequentially (YES in S31), the teacher terminal device 32 generates a code image corresponding to each of the plurality of codes and generates an animation of the code image. , Display (S32). Then, as shown in FIG. 2, the display device 34 displays the animation image of the code image displayed by the teacher terminal device 32 on a relatively large screen or monitor screen in the classroom (S4).

As shown in screens U6, U7, and U8 of the display screen of the teacher terminal device 32 of FIG. 4, the teacher terminal device sequentially displays a plurality of code images CP1, CP2, and CP3 on the display screen and the screen or monitor screen in the classroom. The code image animation is displayed by changing and displaying it. When the display of the plurality of code images while sequentially changing is completed, the display of the code image animation ends and the attendance confirmation ends. In FIG. 4, the display of the code image animation ends after the three code images are displayed in order, but the display is not limited to the three code images, and animations of a plurality of code images other than the three may be displayed.

The code image is a QR (Quick Response) code (registered trademark) in the example of FIG. The QR code includes an image pattern in which the code is encoded. However, the code image is not limited to the QR code.

FIG. 13 is a diagram showing another example of the code image. As shown in FIG. 13, the code image may be, for example, an image in which a white or black pattern is associated with 16 grid-shaped rectangular patterns of 4 rows and 4 columns. In that case, the attendance management server, the teacher terminal device, and the student terminal device store each code image and a code association map. Then, the teacher terminal device refers to the map and generates a code image corresponding to each of the plurality of codes received from the attendance management server. In addition, the student terminal device decodes the captured code image into the corresponding code.

Further, an image containing any pattern or symbol other than the rectangular pattern of 4 rows and 4 columns may be used. The image data of the code image is stored, for example, associated with the code and the code image map.

Next, as shown in FIG. 2, while the display device 34 is displaying the code image animation (S4), the plurality of students activate the attendance management applications of the student terminal devices 36_1 and 36_2, respectively, in the application. Operate the image code image animation button to image the code image animation (S5_1, S5_2).

FIG. 6 is a diagram showing a flowchart of processing by the attendance management application of the student terminal device. Further, FIG. 7 is a diagram showing an example of a user interface displayed by the student terminal device. The student terminal devices 36_1 and 36_2 execute the attendance management application and request login authentication by the attendance management server based on the ID and password entered by the student. When the login is authenticated (YES in S50), the student terminal device displays the image capture button IMG of the code image animation (S51).

U10 of the user interface of FIG. 7 shows an example of the image pickup button IMG of the code image animation. That is, the title of the "attendance application", the image pickup button IMG, the numeric keypad buttons 1 to 0, and the go button GO are displayed on the user interface U10 after login authentication is performed.

As shown in FIG. 6, in the state of the user interface U10 of FIG. 7, when the student operates the image pickup button IMG by pointing the camera of the student terminal device toward the display device 34 according to the attendance confirmation instruction of the teacher (YES in S52), the student terminal The device captures an animation of the code image (S53), decodes the code image into a code based on the map (S54), and sends the decoded code data to the attendance confirmation server (S55). The student terminal device captures the animation of the above code image S53, decodes the code image into the code S54, and sends the code data to the attendance confirmation server S55 until the attendance confirmation is received from the server (YES in S56). And repeat.

As shown in FIG. 7, when the student terminal device captures an animation in which a plurality of code images are sequentially changed, the code images CP1, CP2, and CP3 shown in the user interfaces U11 to U13 are displayed on the display unit at predetermined time intervals. .. This corresponds to the code images CP1, CP2, and CP3 displayed by the teacher terminal device of FIG.

As illustrated in FIG. 7, the student terminal device reads the code image, decodes the code image, and uses the decoded code as the student ID (S in FIG. 7) each time the code image included in the animation is captured. .Watanabe) and send it to the attendance management server each time. In addition to the student ID, the current lecture ID and attendance card management number (attendance card ID) are also added to the code to be sent. Further, the decoding process of the code image is performed by, for example, a QR code library.

Returning to FIG. 2, the attendance management server 10 determines the attendance of the student based on the received code data, and returns the determination result to the student terminal device (S6_1, S6_2). Then, the student terminal device receives the attendance determination result and displays the attendance determination result (S7_1, S7_2). The attendance determination by the attendance management server will be described in more detail below.

As shown in FIG. 5, when the attendance management server receives a series of code data from the student terminal device (YES in S61), whether the received code matches the code generated for the same attendance card in the same lecture. (S62), and further, it is determined whether or not the reception time of the code data is within the threshold time from the corresponding code generation time (S63). This determination is a determination as to whether or not the code matches the code generated within the threshold time before the reception time of the received code.

The attendance management server returns an attendance confirmation to the student terminal device if the judgments S62 and S63 are true for a predetermined number of codes or more (S64), and if any one of the judgments S62 and S63 is false, Attendance confirmation failure is returned to the student terminal device (S65). The predetermined number or more of codes is at least one code or a plurality of codes.

Then, as shown in FIG. 6, when the student terminal device receives the attendance confirmation from the attendance management server (YES in S71), displays the attendance confirmation (S72), and receives the attendance confirmation failure (NO in S71), the student terminal device attends. Display a confirmation failure (S73). An example of the attendance confirmation image CNF is shown in the user interface U14 of FIG. 7.

In FIG. 6, when the student terminal device receives an attendance confirmation failure in addition to receiving the attendance confirmation from the server in S56, or fails to receive the attendance confirmation or attendance confirmation failure within a predetermined time from the start of animation imaging. , Even if the student gives up the attendance confirmation operation, the imaging process of the animation of the code image of the processes S53 to S55 is finished.

If the student terminal device cannot receive the attendance confirmation, the teacher terminal device may be able to perform the attendance confirmation as an exception during the break time or after the class. In that case, the attendance confirmation determined by the teacher terminal device is transmitted to the attendance management server and stored in the attendance management server.

FIG. 8 is a diagram illustrating a determination process of attendance confirmation by the attendance management server. As described above, when the attendance management server 10 receives the code image animation display request from the teacher terminal device, it generates a plurality of codes at dt1 intervals (for example, every 2 seconds) or at predetermined time intervals for a fixed period of time, and generates a plurality of codes. Is sent to the teacher terminal device each time the code is generated. In the example of FIG. 8, the attendance management server generates the respective codes at the times t1, t2, and t3 on the time axis t from the top to the bottom, and transmits them to the teacher terminal device.

In response to the reception of this code, the teacher terminal device 32 generates code images CP1, CP2, and CP3 corresponding to the code, respectively, and displays an animation for displaying these code images in order. Then, when the student terminal device 36 captures the animation, it decodes the code corresponding to the code images displayed in order in the animation, and transmits the code data to the attendance management server 10 each time the code is decoded.

Then, the attendance management server 10 determines whether or not the reception code matches the code generated within the threshold time dt2 before the reception time in the attendance determination. If more than a predetermined number of codes match in succession, the attendance management server confirms the student's attendance. The predetermined number or more is, for example, one or more or a plurality or more. This determination corresponds to the determinations S61 to S63 in FIG.

Alternatively, the attendance management server may confirm the attendance of students when a predetermined number or more of codes match in a predetermined intermittent pattern. Matching in a predetermined intermittent pattern means, for example, that the intermittent codes CD1, CD3, and CD5 match the consecutive codes CD1, CD2, CD3, CD4, and CD5.

The above-mentioned determination process of attendance confirmation holds the following when a series of code data is transmitted from a student terminal device of a student and the student is really transmitting the code data from the classroom. That is, (1) for example, three consecutive codes transmitted by the student terminal device match the three consecutive codes generated by the attendance management server. Further, (2) if the student terminal device captures the code image in the animation and immediately transmits it, the code reception time is within the threshold time dt2 from the code generation time. For example, the code generation interval dt1 is set to 2 seconds as described above, and the threshold time dt2 is set to 5 seconds. In this case, the relationship between the code generation interval dt1 and the threshold time dt2 is not dt1> dt2 shown in FIG. 8, but dt1 <dt2.

Therefore, in the attendance management server, (1) the generated series of codes and the series of codes received from the student terminal device match a certain number or more, or (2) the received code is the threshold time before the reception time. Attendance is determined when the two conditions of whether it was generated within (allowable time) are satisfied.

As one method of attendance confirmation, the teacher terminal device displays a single code image, and the student terminal device sends the code of the code image to the attendance management server, but the attendance confirmation is performed. .. In this case, if the student terminal device outside the classroom that is not attending receives the code image from the student terminal that is attending and sends the code to the attendance confirmation server, the attendance confirmation can be obtained illegally.

In order to prevent this, in the attendance confirmation of the present embodiment, it is determined whether or not the reception code matches the code generated within the threshold time before the reception time. As a result, if the code is received after the threshold time elapses from the code generation time because it takes time to transfer the code image to the student terminal outside the classroom, attendance confirmation is not performed. The threshold time is set short enough to prevent the above fraud.

However, if a single code image is displayed and it is determined whether or not the code received within the threshold time from the code generation time matches the generated code, the student when the teacher gives an instruction to confirm attendance. If the imaging is not successful promptly, attendance confirmation cannot be obtained.

Therefore, in the present embodiment, the teacher terminal device displays an animation in which a plurality of unique code images are sequentially changed, and the attendance management server continues a predetermined number or more of the plurality of code images received from the student terminal device. Alternatively, it is determined whether or not the intermittent code matches the code generated within the threshold time before the reception time.

Next, it is assumed that the student terminal device saves the captured animation and then transfers the animation movie to the student terminal device outside the classroom. In this case, the animation video is transferred to the student terminal device outside the classroom with a delay of more than the time, so the attendance management server determines whether the reception code matches the generation code generated within the threshold time before the reception time. By determining whether or not it is possible, such fraud can be prevented.

In addition, it is assumed that the student terminal device transfers the captured animation to the student terminal device outside the classroom via the Internet relay. However, the animation relayed on the Internet requires a certain amount of communication resources (terminal function, wireless communication speed) in order to clearly relay the images of all frames, so that the moving image is usually deteriorated. Therefore, even if it is relayed on the net, it is difficult to capture the code image in the animation relayed on the net and decode it into a code. In addition, by assuming net relay and shortening the threshold time dt2, fraud due to net relay can be prevented. For example, the code generation interval dt1 is set to 2 seconds, and the threshold time dt2 is set to 0.2 seconds. In this case, as shown in FIG. 8, the threshold time dt2 is shorter than the code generation interval dt1. In order to relay the animation video on the Internet, a certain delay occurs because the animation video is compressed, transmitted, and decoded. Due to this delay, the condition that the threshold time is within dt2 is not satisfied.

In the above case, the student terminal device must capture each code image in the animation from the start of display. However, since it is determined that a predetermined number or more of the received codes from any code image among the plurality of code images displayed continuously in the animation match the generated code generated within the threshold time before the reception time. ,No problem.

[Second Embodiment]
FIG. 10 is a sequence diagram showing an attendance confirmation process by the attendance management system according to the second embodiment. Unlike the first embodiment shown in FIG. 2, in the example of FIG. 10, the attendance management server 10 continuously generates a plurality of unique codes in response to the animation display request S1_2, and further, An animation of the code image is generated and transmitted to the teacher terminal device 32 (S2A), and the teacher terminal device 32 displays the animation of the received code image (S3A). Therefore, the teacher terminal device 32 does not need to convert a plurality of codes into a code image and generate an animation of the code image.

Due to the change in the processing S2A of the attendance management server of FIG. 10 and the processing S3A of the teacher terminal device, the animation of the code image is received from the attendance management server in the processing of the teacher terminal of FIG. 3, and the attendance management server of FIG. In the process of, a code image is generated from the generated code, and an animation of the code image is generated and transmitted.

According to the second embodiment, the attendance management server can store the code image display time in addition to the code generation time. Therefore, the attendance management server also stores the time when the code image corresponding to the code is displayed in the code history stored when the code is generated, so that the reception code is the threshold time before the reception time in the attendance confirmation determination. It is also possible to determine whether or not the code matches the code displayed in.

[Third Embodiment]
FIG. 11 is a sequence diagram showing a process of attendance confirmation by the attendance management system according to the third embodiment.

In the third embodiment, the attendance management server 10 and the teacher terminal device 32 of the first and second embodiments are replaced with one teacher server 10/32. Therefore, the teacher server 10/32 has a function as a server, and in response to the animation display request S1_2 for confirmation of attendance by the teacher, the teacher server generates a plurality of consecutive codes, and each of the generated codes is generated. Generate a code image and display an animation in which the code image changes sequentially (S2A).

In addition, the teacher server determines attendance confirmation as to whether or not the code received from the student terminal device matches the code generated within the threshold time before the reception time (S6_1, S6_2). Further, the teacher server may determine attendance confirmation as to whether or not the code received from the student terminal device matches the code of the code image displayed within the threshold time before the reception time.

[Fourth Embodiment]
FIG. 12 is a diagram showing an attendance confirmation process of the student terminal device according to the fourth embodiment. The fourth embodiment is a countermeasure when the function of online relay of moving images evolves in the future. In the first and second embodiments, the student terminal device converts the animation code image into a code and transmits the code data to the attendance management server.

On the other hand, in the fourth embodiment, when the student operates the imaging button IMG of the code image animation, the student terminal device converts the captured animation code image into a code and converts the code data into an attendance management server. The image data ROOM_IMG1 of the captured image (one frame image) is also transmitted to the attendance management server. In FIG. 12, the image ROOM_IMG1 captured by the student terminal device in the classroom shown on the upper side is, in addition to the image of the display device 34 that displays the animation of the code image, the surrounding image such as the image of the teacher T who is on the stage. Is also included.

In the attendance confirmation, the attendance management server determines whether or not the received code matches the generated code within the threshold time before the reception time, as in the first and second embodiments. Teachers visually check the image ROOM_IMG1 in the classroom.

In FIG. 12, the image ROOM_IMG2 captured by the student terminal device outside the classroom shown on the lower side is an image ROOM_IMG1 having a display device 34 captured in the classroom and an image T around it, and a classroom displaying the image ROOM_IMG1. An image of the outside student terminal device 36 is included. The student terminal device outside the classroom sends the code data obtained by decoding the animation code image to the attendance management server, but cannot send the image data ROOM_IMG1 of the captured image in the classroom.

In attendance confirmation, it is possible to detect that the teacher or the like is confirming attendance from outside the classroom by visually judging the image ROOM_IMG2 outside the classroom.

[Fifth Embodiment]
In the fifth embodiment, instead of the image data ROOM_IMG1 of the captured image transmitted in the fourth embodiment, the student shakes the student terminal device in either the left or right direction based on the instruction of the teacher to capture the image. And the movement operation information of the student terminal device generated by swinging the student terminal device in either the left or right direction, for example, the acceleration sensor value, is transmitted to the attendance management server.

The student terminal device outside the classroom can obtain the image captured when the student terminal device in the classroom is shaken in the left-right direction, but cannot obtain the moving operation information of the student terminal device. Therefore, it is possible to detect that attendance is confirmed from outside the classroom.

[Sixth Embodiment]
In the sixth embodiment, when the attendance confirmation server determines the attendance confirmation, each student terminal device performs the code of the code image of the series of code images within the threshold time before the code reception time. Outputs information as to whether it matches the generated code. For example, the teacher starts the animation display at an arbitrary timing without notifying the student in advance when to display the animation for attendance confirmation. On the other hand, each student operates each student terminal device in response to the animation display, and performs an imaging operation for attendance confirmation.

As a result, the attendance confirmation server can output information on which code image each student was able to confirm attendance in a series of code images, enabling the most battle of attendance confirmation between students. it can.

Students are also expected to actively take the central seat in front of the classroom in order to capture high quality animations during the first attendance confirmation battle. As a result, the lesson can be activated.

Further, as a modification of the sixth embodiment, the teacher terminal device displays the attendance confirmation management number in the animation, and the student is presented with the screen of the user interface U10 of the student terminal device shown in FIG. You may be required to operate the image pickup button IMG after entering the attendance confirmation control number with the numeric keypad. By doing so, it is possible to make the students compete for the speed of the operation of inputting the management number of attendance confirmation with the numeric keypad, and to enable the most battle of attendance confirmation between students.
