(First embodiment)
Embodiments will be described below with reference to the drawings. FIG. 1 is a diagram for explaining a comment display system.

  The comment display system 100 includes a comment display server 200 and a terminal device 300. In the comment display system 100, the comment display server 200 and the terminal device 300 are connected via a network. The terminal device 300 is distributed, for example, to each learner (hereinafter referred to as a student) participating in a lesson, and there are as many as the number of students. In the following description, the terminal device 300 is referred to as the terminal device 301, 302,..., 30N when distinguishing each of the plurality of terminal devices, and is simply referred to as the terminal device 300 when not distinguishing the plurality of terminal devices. .

  In the comment display system 100 of this embodiment, for example, when a student's comment is input (posted) through the terminal device 300 during a class, the input comment is transmitted to the comment display server 200 and stored in the comment database. The In addition, the comment display server 200 displays the comments in the comment database on each terminal device 300, and allows each learner to share the posted comments.

  A screen 310 illustrated in FIG. 1 is a comment screen of the terminal device 301. For example, in the terminal device 301, when a student inputs a comment related to lesson contents in the comment input field 311 and operates the transmission button 312, the input comment is transmitted to the comment display server 200 and stored. In the comment display server 200, the comments inputted in the other terminal devices 302 to 30N are similarly accumulated. The comment display server 200 displays the comment input in the other terminal devices 302 to 30N in the shared comment display field 313 of the comment screen 310. At this time, the terminal device 300 separately performs an input comment display field 314 for displaying a comment input by the student in the shared comment display field 313 and an other person comment display field 315 for displaying a shared comment posted by another student. Display.

  In the comment display system 100, the comments input from the respective terminal devices 300 are tabulated by the comment display server 200 and displayed on each terminal device 300, so that each student's comments are shared.

  Further, the comment display system 100 according to the present embodiment adjusts the amount of comments to be displayed in the shared comment display field 313 of the terminal device 300 in the comment display server 200 according to the degree of concentration of each student, and displays it on the terminal device 300. Let

  The amount of comments a student can read decreases as the degree of concentration decreases. The degree of concentration generally decreases with time. The degree of concentration also decreases when, for example, the student is not interested in the content of the lesson. When the degree of concentration decreases, it is preferable that the amount of comments displayed in the shared comment display column is smaller than that immediately after the start of the lesson. In the following description, a comment displayed in the shared comment display field of the terminal device 300 is referred to as a shared comment.

  Also, the degree of concentration tends to increase, for example, in the part where students are interested in the class. To be interested or to be interested is to have a question or to have a new discovery that has never been seen before. When the degree of concentration is high, it is preferable to have a large amount of shared comments because it is possible to deepen learning and understanding by thinking about yourself.

  In the present embodiment, considering the above, the amount of shared comments is adjusted according to the degree of concentration of students. In addition, the comment of a present Example may be specifically text data.

  FIG. 2 is a diagram illustrating an example of a hardware configuration of the comment display server. The comment display server 200 according to the present embodiment includes an input device 21, a drive device 22, an auxiliary storage device 23, a memory device 24, an arithmetic processing device 25, an interface device 26, and an output device 27 that are connected to each other via a bus B. Have.

  The input device 21 is a keyboard, a mouse, or the like, and is used for inputting various information and signals. The interface device 26 includes a modem, a LAN card, etc., and is used for connecting to a network. The output device 27 is a display or the like, for example, and is used for displaying various information.

  The comment display program is at least a part of various programs that control the comment display server 200. The comment display program is provided by, for example, distribution of the recording medium 28 or downloading from a network. The recording medium 28 on which the comment display program is recorded is information such as a CD-ROM, a flexible disk, a magneto-optical disk, etc., a recording medium for recording information optically, electrically or magnetically, a ROM, a flash memory, etc. Various types of recording media, such as a semiconductor memory that electrically records data, can be used.

  When the recording medium 28 on which the comment display program is recorded is set in the drive device 22, the comment display program is installed from the recording medium 28 to the auxiliary storage device 23 via the drive device 22. The comment display program downloaded from the network is installed in the auxiliary storage device 23 via the interface device 26.

  The comment display server 200 stores the installed comment display program and stores necessary files, data, and the like in the auxiliary storage device 23. The memory device 24 reads and stores the comment display program from the auxiliary storage device 23 when the computer is activated. The arithmetic processing unit 25 implements various processes as described later according to the comment display program stored in the memory device 24.

  Note that the comment display server 200 of this embodiment has a display operation device instead of the input device 21 and the output device 27 in the case of a tablet computer, for example.

  Since the hardware configuration of the terminal device 300 of this embodiment is the same as that of the comment display server 200, the description thereof is omitted. Note that the terminal device 300 according to the present embodiment may be a tablet computer, a mobile phone, a smartphone, or the like. In that case, the terminal device 300 includes a display operation device having a display function and an input function instead of the input device and the output device.

  The functions of the comment display server 200 and the terminal device 300 according to this embodiment will be described below with reference to FIG. FIG. 3 is a diagram for explaining functions of the comment display server and the terminal device.

  The comment display server 200 of this embodiment includes a comment database 210 and a shared student database 220. Each database may be provided in a predetermined area of the auxiliary storage device 23, for example. The comment database 210 stores comments input from each terminal device 300. In the shared student database 220, students who share comments for each student are set. Details of each database will be described later.

  In addition, the comment display server 200 of this embodiment includes an elapsed time measurement unit 230, a comment acquisition unit 240, a time adjustment value calculation unit 250, a comment amount adjustment value calculation unit 260, a threshold value calculation unit 270, and a display comment determination unit 280.

  The comment display server 200 according to the present embodiment calculates a time adjustment value based on the elapsed time and a comment amount adjustment value based on the amount of the input comment, and calculates the amount of shared comments to be displayed using the two adjustment values. The threshold value to be determined is calculated. Then, the comment display server 200 determines a shared comment according to the calculated threshold value. In this embodiment, the comment amount is described as the number of characters in the comment, but the present invention is not limited to this. The comment amount may be indicated by, for example, the number of posted comments, the number of contributors who have posted comments, and the like.

  The elapsed time measuring unit 230 measures the passage of time since the lesson started. The comment acquisition unit 240 acquires comments stored in the comment database 210. The time adjustment value calculation unit 250 calculates a time adjustment value based on the measurement result of the elapsed time by the elapsed time measurement unit 230. The comment amount adjustment value calculation unit 260 calculates a comment amount adjustment value based on the comment amount acquired by the comment acquisition unit 240.

  The threshold calculation unit 270 calculates a threshold for determining the amount of comment to be displayed as a shared comment from the time adjustment value and the comment amount adjustment value. Details of the processes of the time adjustment value calculation unit 250, the comment amount adjustment value calculation unit 260, and the threshold value calculation unit 270 will be described later.

  The display comment determination unit 280 determines a comment to be displayed as a shared comment on the terminal device 300 from the comments stored in the comment database 210. More specifically, the display comment determination unit 280 determines the shared comment so that the amount of the shared comment is equal to or less than the threshold calculated by the threshold calculation unit 270. Further, the display comment determination unit 280 according to the present embodiment also determines a comment to be displayed on the terminal device 300 in addition to the shared comment. Specifically, the display comment determination unit 280 causes the terminal device 300 to display a comment input from the terminal device 300 as a comment of a student who is a user of the terminal device 300.

  The terminal device 300 according to the present embodiment includes a comment input unit 330, a comment registration unit 331, and a comment display unit 332. For example, the comment input unit 330 receives a comment input in the comment input field 311 of the screen 310 illustrated in FIG. The comment registration unit 331 registers the comment received by the comment input unit 330 in the comment display server 200. Specifically, the comment registration unit 331 transmits the accepted comment to the comment display server 200. The comment display server 200 receives comments from the terminal device 300 and stores them in the comment database 210.

  The comment display unit 332 displays the comment determined as the shared comment in the comment display server 200 on the display operation device or the like of the terminal device 300. The comment display unit 332 according to the present embodiment displays the comment input by the user and the shared comment separately.

  FIG. 4 is a diagram illustrating an example of a comment database. The comment database 210 according to the present embodiment stores a user ID, a comment posting time, and a comment content in association with each other. The user ID is, for example, a student ID for identifying a student who is using the terminal device 300, and is given in advance by an administrator of the comment display system 100 or the like. The posting time is, for example, the time when a comment is stored in the comment database 210, and may be stored simultaneously when the comment is stored in the comment database 210.

  FIG. 5 is a diagram illustrating an example of a shared student database. In the shared student database 220 of this embodiment, the user ID and the shared information are associated with each other.

  The shared information indicates the priority of the partner with whom each student shares a comment. For example, in the shared student database 220 shown in FIG. 5, a student whose user ID is A shares a comment with students whose user IDs are B, C, and D. In this case, the priority of the partner with whom the student whose user ID is A shares the comment may be the order in which the user IDs of the sharing partner are stored. That is, the specific priority order is a student whose user ID is B, a student whose user ID is C, and a student whose user ID is D. The shared information according to the present embodiment may be given in advance by, for example, selecting a student who shares a comment in advance in the terminal device 300 in order of priority before the lesson starts.

  In the shared student database 220 according to the present embodiment, a user ID with a priority order may be provided. For example, information indicating that the priority of the sharing partner with whom the user ID is A is the order of the students with the user IDs B, C, D, and E may be stored.

  Next, the time adjustment value and comment amount adjustment value of this embodiment will be described.

  The number of comment characters that a student can read per predetermined time varies depending on the degree of concentration of the student. In this embodiment, if the number of comment characters that a student can read per predetermined time without missing the class is S, the time adjustment value and the comment amount adjustment value are the amount of change in the number of comment characters S according to the degree of concentration. is there.

  The time adjustment value indicates a change amount of the comment character number S due to a change in the degree of concentration according to the elapsed time. The comment amount adjustment value is a change amount of the comment character number S due to a change in the degree of concentration according to the interest in the lesson contents and how to hold the interest.

  In this embodiment, the threshold TH for determining the amount of shared comments is calculated using the maximum value Smax of the number S of comment characters, the time adjustment value, and the comment amount adjustment value.

  The maximum value Smax of the number of comment characters S is the maximum value of the number of comment characters that a student can read without missing the class per predetermined time. The maximum value Smax is obtained by experiments. For example, the maximum value Smax can be obtained from the result of an experiment in which the number of characters in a comment that can be read without listening to a lesson is measured a plurality of times.

  Also, the amount of shared comments in this embodiment is indicated by the total number of characters in the shared comments.

  FIG. 6 is a diagram for explaining the time adjustment value.

  In this embodiment, an elapsed time t from the start of the lesson is used as one index for determining the degree of student concentration, and a time adjustment value is obtained. In this embodiment, when the time adjustment value is a function F (t), the function F (t) can be obtained by experiment. Note that t is the elapsed time, and the unit is seconds. For example, the function F (t) can be obtained from the result of an experiment in which the number of comment characters that can be read without listening to a class is missed every time a predetermined time elapses.

  In the example of FIG. 6, when the elapsed time t is 30 minutes, the comment character count S is reduced by 30 characters. Therefore, the time adjustment value is 30 characters. When the elapsed time t is 60 minutes, the comment character number S is reduced by 60 characters. Therefore, the time adjustment value is 60 characters. The time adjustment value calculation unit 250 of this embodiment calculates the time adjustment value by substituting the elapsed time t measured by the elapsed time measurement unit 220 into the function F (t).

  FIG. 7 is a diagram for explaining the comment amount adjustment value of the first embodiment.

  In this embodiment, the comment amount adjustment value is obtained by using the number of characters p of comments input by the student at a predetermined time as another index for judging the degree of concentration of the student. In this embodiment, when the comment amount adjustment value is a function G (p), the function G (p) can be obtained by experiments. For example, the function G (p) is obtained by performing an experiment of measuring the number of comment characters p input by a student per predetermined time and the number of comment characters S that can be read without listening to the lesson per predetermined time. it can.

  In the present embodiment, when the number of comment characters p is large, it indicates that the student is interested in the content of the lesson, and it is assumed that the degree of concentration is increasing. When the number of comment characters p is small, it is assumed that the student's interest and interest in the lesson content is low and the degree of concentration is low. The number S of comment characters increases when the degree of concentration is high and decreases when the degree of concentration is low.

  In FIG. 7, for example, the predetermined time is 60 seconds. When the number of comment characters p input in FIG. 7 is 30, the number of comment characters S increases by 60 characters. Therefore, the comment amount adjustment value is 60 characters. Similarly, for example, when the number of input comment characters p is 100, the number of comment characters S increases by 80 characters. Therefore, the comment amount adjustment value is 80 characters.

  The comment amount adjustment value calculation unit 260 according to the present embodiment calculates the comment amount adjustment value by substituting the number of comment characters p input to the terminal device 300 into the function G (p). The number of comment characters p may be acquired from, for example, comments stored in the comment database 210.

  Next, the threshold value TH calculated by the threshold value calculation unit 270 will be described. The threshold value TH in this embodiment is a value for determining the upper limit of the total number of characters of shared comments displayed in the shared comment display field 313 of the terminal device 300.

  The threshold value TH in this embodiment is given by the following formula 1 when the time adjustment value is F (t) and the comment amount adjustment value is G (p).

Threshold TH = min ((Smax−F (t) + G (p)), Smax) Equation 1
In other words, the threshold value TH of the present embodiment is a smaller value between the maximum value Smax, the value obtained by subtracting the time adjustment value F (t) and further adding the comment amount adjustment value G (p), and the maximum value Smax. .

  The display comment determination unit 280 according to the present embodiment determines the shared comment so that the total number of characters of the shared comment does not exceed the threshold value TH. Therefore, in the present embodiment, the number of characters of the shared comment can be determined in accordance with the change in the degree of concentration.

  The operation of the comment display server 200 of this embodiment will be described below with reference to FIG. FIG. 8 is a flowchart for explaining the operation of the comment display server of the first embodiment.

  The comment display server 200 according to the present embodiment executes the process illustrated in FIG. 8 for each of the plurality of terminal devices 300.

  In the comment display server 200 according to the present embodiment, the time adjustment value calculation unit 250 acquires the elapsed time t from the start of the class measured by the elapsed time measurement unit 230 (step S801). Subsequently, the time adjustment value calculation unit 250 calculates a time adjustment value F (t) t seconds after the lesson starts (step S802). The function F (t) indicating the time adjustment value is stored in advance in the auxiliary storage device 23 of the comment display server 200, for example.

  Subsequently, the comment display server 200 uses the comment acquisition unit 240 to acquire a comment stored for a predetermined time from the comment database 210 (step S803). In this embodiment, the predetermined time is N seconds.

  When the comment display server 200 according to the present embodiment acquires a comment stored in the comment database 210 during N seconds, the comment display server 200 displays a comment input by a student who uses the terminal device 300 and a shared comment. The display process is performed. In the following, a process for displaying a comment input by a student who uses the terminal device 300 on the terminal device 300 will be described.

  Following step S803, the comment display server 200 causes the display comment determination unit 280 to extract a comment whose user ID matches the user ID of the comment poster from the comment acquired in step S803 (step S804). In this embodiment, for example, when the comment display server 200 executes a process of displaying a comment on the terminal device 301, the user ID of the student who uses the terminal device 301 is the user of the comment poster. ID. The comment display server 200 according to the present embodiment may include a table in which the terminal devices 301 to 30N and the user IDs of students who use the terminal devices 301 to 30N are associated with each other.

  Subsequently, the display comment determination unit 280 displays the comment extracted in step S804 in the input comment display field 314 for displaying the comment input by itself on the screen 310 of the terminal device 300 (step S805).

  When the comment display server 200 executes Step S805, the comment display server 200 ends the process of displaying the comment input by the student who uses the terminal device 300.

  Next, processing for displaying a shared comment will be described.

  Following step S803, the comment display server 200 uses the comment acquisition unit 240 to extract comments posted by students who are users of the terminal device 300 from the comment database 210 for N seconds (step S806). Specifically, the comment acquisition unit 240 extracts a comment whose user ID matches the user ID of the comment poster from the comments stored in the comment database 210 for N seconds.

  Subsequently, the comment amount adjustment value calculation unit 260 calculates the total number of characters of the comments extracted in step S806 (step S807). The number of characters calculated in step S807 is the number of comment characters p input by the student in N seconds. Subsequently, the comment amount adjustment value calculation unit 260 calculates the comment amount adjustment value G (p) (step S808).

  Next, the comment display server 200 calculates the threshold value TH by the threshold value calculation unit 270. Specifically, the threshold value calculation unit 270 determines whether or not Smax−F (t) + G (p)> Smax is satisfied (step S809). The maximum value Smax here is a maximum value of the number of comment characters that a student can read without missing a class in N seconds and is given in advance.

  When Smax−F (t) + G (p)> Smax is satisfied in step S809, the threshold value calculation unit 270 sets the maximum value Smax as the threshold value TH (step S810). When Smax−F (t) + G (p)> Smax is not satisfied in step S809, the threshold value calculation unit 270 sets the value of Smax−F (t) + G (p) as the threshold value TH (step S811).

  Subsequently, the comment display server 200 uses the display comment determination unit 280 to extract a comment whose user ID does not match the user ID of the comment poster from the comment acquired in step S803 (step S812). That is, the display comment determination unit 280 extracts comments from students other than those who use the terminal device 300.

  Subsequently, the display comment determination unit 280 refers to the shared student database 220 and rearranges the corresponding comments in descending order of priority of the comment sharing partner (step S813).

  The display comment determination unit 280 sets the variable i = 1 and the total number of characters C of the shared comment C = 0 (step S814). Subsequently, the display comment determination unit 280 sets the total number of characters of the shared comment C = C + Ci, and adds the number of comment characters of the comment extracted in step S812 in accordance with the priority order (step S815).

  Subsequently, the display comment determination unit 280 determines whether or not the total number C of characters in the shared comment exceeds the threshold value TH (step S816). If the total number C of characters in the shared comment is equal to or smaller than the threshold value TH in step S816, the display comment determination unit 280 sets the variable i = i + 1 (step S817) and returns to step S815.

  When the number of comment characters is larger than the threshold value TH in step S816, the display comment determination unit 280 sets the variable Di = i−1 (step S818), and extracts the comments from the comment extracted in step S812 to the Dith (step S819). . In this embodiment, the comment extracted in step S819 becomes a shared comment.

  Subsequently, the display comment determination unit 280 rearranges the comments extracted in step S819 in the order of posting with reference to the comment database 210 (step S820). Subsequently, the display comment determination unit 280 displays the comments rearranged in step S820 in the other person comment display field 315 of the terminal device 300 (step S821).

  The process for displaying the shared comment of this embodiment will be specifically described below with reference to FIG. FIG. 9 is a diagram for explaining processing for displaying a shared comment in the first embodiment. In the example of FIG. 9, the user ID of the student who uses the terminal device 300 is A.

  FIG. 9A shows an example of the comment extracted in step S803. The comment extracted in step S803 is a comment stored in the comment database 210 for N seconds. In FIG. 9A, both the comments posted by the user of the terminal device 300 and the comments posted by others are extracted and arranged in order of posting time.

  FIG. 9B shows the comment in step S813. The comment shown in FIG. 9B is obtained by extracting comments other than the user ID A from the comments shown in FIG. This is an example. According to the shared student database 220, the priority of the sharing partner of the student with the user ID A is the student with the user ID B, the student C, and the student D. Therefore, in FIG. 9B, the comments are rearranged in this order.

  FIG. 9C shows the shared comment extracted in step S819. In FIG. 9C, the shared comment is determined so that the total number of characters C is equal to or less than the threshold value TH. In the example of FIG. 9, the threshold value TH = 250 characters. Therefore, the display comment determination unit 280 extracts the comments shown in FIG. 9B from the comments with the highest priority, and when the total number of extracted comments exceeds 250 characters, the comment extracted before that is shared. Comment.

  FIG. 9D shows a state where the shared comments are rearranged in order of posting time in step S820. In the terminal device 300 according to the present embodiment, the shared comments are preferably displayed in the order shown in FIG.

  FIG. 10 is a diagram illustrating an example of a shared comment display field according to the first embodiment. The shared comment display field 313A shown in FIG. 10 is displayed on the display device of the terminal device 300 or the like. In the shared comment display field 313A of this embodiment, there are an input comment display field 314A for displaying a comment input by itself and an other person comment display field 315A for displaying a shared comment that is a comment input by another person. included.

  In the present embodiment, the number of characters of the shared comment displayed in the other person comment display field 315A is equal to or less than the threshold value TH.

  As described above, in this embodiment, the elapsed time t from the start of the lesson and the number of comment characters p entered by the student within the predetermined time are used as indices for judging the degree of concentration of the student. An upper threshold TH is provided. Therefore, in this embodiment, the amount of shared comments can be adjusted and displayed in accordance with the degree of concentration of students who are users of the terminal device 300.

  In the present embodiment, priority is provided to the parties sharing the comment. Therefore, in the present embodiment, it is possible to display the comments of others who are considered useful by the student without disturbing listening to the lesson.

(Second embodiment)
The second embodiment will be described below with reference to the drawings. In the second embodiment, the elapsed time from the start of the lesson and the total number of characters of comments posted by all other students who participated in the lesson within the predetermined time are used as indices indicating the degree of student concentration. In the following description of the second embodiment, only differences from the first embodiment will be described, and those having the same functional configuration as the first embodiment are used in the description of the first embodiment. The same reference numerals as the reference numerals are assigned, and the description thereof is omitted.

  In this example, the amount of comments is adjusted by using the elapsed time from the start of the lesson and the total number of characters of all comments entered by students other than yourself who participated in the lesson within the specified time as an index for judging the degree of student concentration. Find the value.

  FIG. 11 is a diagram for explaining the comment amount adjustment value of the second embodiment.

  In this embodiment, when the comment amount adjustment value is the function G2 (p1), the function G2 (p1) can be obtained by experiment. The function G2 (p1) is an experiment that measures, for example, the total number of characters p1 of all comments input by students other than yourself per predetermined time and the number of comment characters S that the student can read without missing the class per predetermined time. Can be obtained from the experimental results.

  In this example, if the total number of characters p1 of all comments entered by students other than yourself is large, it is an important part that many students are interested in and interested in the course contents. Assume that is growing. In addition, when the total number of characters p1 is small, it is assumed that the student's overall interest and interest in the lesson content is low and the degree of concentration is low. The number S of comment characters increases when the degree of concentration is high and decreases when the degree of concentration is low.

  In FIG. 11, for example, the predetermined time is 60 seconds. In FIG. 11, when the total number of characters p1 of all comments input by students other than yourself per predetermined time is 200 characters, the number of comment characters S increases by 20 characters. Therefore, the comment amount adjustment value is 20 characters. Similarly, for example, when the total character number p1 is 500 characters, the comment character number S increases by 60 characters. Therefore, the comment amount adjustment value is 60 characters.

  In the present embodiment, the comment amount adjustment value calculation unit 260 substitutes the total amount of characters p1 of all comments input by students other than yourself who participated in the class within a predetermined time into the function G2 (p1). Calculate the value.

  The operation of the comment display server 200 of this embodiment will be described below with reference to FIG. FIG. 12 is a flowchart for explaining the operation of the comment display server of the second embodiment.

  The processing from step S1201 to step S1205 in FIG. 12 is the same as the processing from step S801 to step S805 in FIG.

  The comment display server 200 executes processing for displaying the shared comment from step S1206.

  Following step S1203, the comment display server 200 causes the comment acquisition unit 240 to extract, from the comment database 210, comments posted by students other than students who are users of the terminal device 300 for N seconds (step S1206). Specifically, the comment acquisition unit 240 extracts a comment whose user ID does not match the user ID of the comment poster from the comments stored in the comment database 210 for N seconds.

  Subsequently, the comment amount adjustment value calculation unit 260 calculates the total number of characters p1 of all comments extracted in step S1206 (step S1207). Subsequently, the comment amount adjustment value calculation unit 260 calculates the comment amount adjustment value G2 (p1) (step S1208).

  Next, the comment display server 200 calculates the threshold value TH by the threshold value calculation unit 270 (step S1209). The threshold value TH in the present embodiment is given by the following formula 2.

Threshold TH = min ((Smax−F (t) + G2 (p1)), Smax) Equation 2
Therefore, the threshold value calculation unit 270 determines whether or not Smax−F (t) + G2 (p1)> Smax is satisfied in step S1209.

  When Smax−F (t) + G2 (p1)> Smax is satisfied in step S1209, the threshold value calculation unit 270 sets the maximum value Smax as the threshold value TH (step S1210). If Smax−F (t) + G2 (p1)> Smax is not satisfied in step S1209, the threshold value calculation unit 270 sets the value of Smax−F (t) + G2 (p1) as the threshold value TH (step S1211).

  The processing from step S1212 to step S1221 is the same as the processing from step S812 to step S821 in FIG.

  The process for displaying the shared comment of this embodiment will be specifically described below with reference to FIG. FIG. 13 is a diagram for explaining processing for displaying a shared comment in the second embodiment. In the example of FIG. 13, the user ID of the student who uses the terminal device 300 is A.

  FIG. 13A shows an example of a comment extracted in step S1203. The comment extracted in step S1203 is a comment stored in the comment database 210 for N seconds. In FIG. 13A, both the comments posted by the user of the terminal device 300 and the comments posted by others are extracted and arranged in order of posting time.

  FIG. 13B shows the comment in step S1213. The comments shown in FIG. 13B are extracted from the comments shown in FIG. 13A with the user ID other than A, and then the shared student database 220 is referred to and the comments of the sharing partner with the highest priority are viewed from above. This is an example. FIG. 13C shows the shared comment extracted in step S1219. In FIG. 13C, the shared comment is determined so that the total number of characters C is equal to or less than the threshold value TH. In the example of FIG. 13, the threshold value TH = 230 characters. Therefore, the display comment determination unit 280 extracts the comments shown in FIG. 13B from the comments with high priority, and when the total number of extracted comments exceeds 230 characters, the comment extracted before that is shared. Comment.

  FIG. 13D shows a state in which the shared comments are rearranged in order of posting time in step S1220. In the terminal device 300 according to the present embodiment, the shared comments shown in FIG. 13D are displayed in the other comment column 315A in the shared comment display column 313A in the order shown in FIG. 13D.

  As described above, in this embodiment, the elapsed time t from the start of the lesson and the total number of characters p1 of all comments input by students other than yourself within a predetermined time are displayed as indices for judging the degree of student concentration. A threshold TH that is the upper limit of the number of characters of shared comments to be made is provided. Therefore, in this embodiment, it is possible to display a shared comment having the number of characters corresponding to the degree of concentration of students who are users of the terminal device 300.

(Third embodiment)
A third embodiment will be described below with reference to the drawings. In the third embodiment, the elapsed time from the start of the lesson and the number of students who have posted comments other than themselves who participated in the lesson within a predetermined time are used as indicators indicating the degree of concentration. In the following description of the third embodiment, only differences from the first embodiment will be described, and those having the same functional configuration as the first embodiment are used in the description of the first embodiment. The same reference numerals as the reference numerals are assigned, and the description thereof is omitted.

  In this example, the elapsed time from the start of the lesson and the number of students who posted comments (hereinafter referred to as the number of other commenters) other than yourself who participated in the lesson within the prescribed time are shown as the number of students. The comment amount adjustment value is obtained as an index for judging the degree of concentration.

  FIG. 14 is a diagram for explaining the comment amount adjustment value of the third embodiment.

  In this embodiment, when the comment amount adjustment value is the function G3 (n), the function G3 (n) can be obtained by experiment. For example, the function G3 (n) performs an experiment of counting the number of comment authors n other than yourself within a predetermined time while measuring the number of comment characters S that a student can read without missing the class per predetermined time. It can be obtained from the result.

  In this embodiment, it is assumed that when there are a large number of comment contributors n other than myself, many students are important portions of interest and interest in class content, and the degree of concentration of students is increasing. In addition, when the number n of commenters other than yourself is small, it is assumed that the student's interest and interest in the lesson contents are generally weak and the degree of concentration of the student is decreasing. The number S of comment characters increases when the degree of concentration is high and decreases when the degree of concentration is low.

  In FIG. 14, for example, the predetermined time is 60 seconds. In FIG. 14, when the number of comment contributors other than yourself is five, the number of comment characters S increases by 20 characters. Therefore, the comment amount adjustment value is 20 characters. Similarly, for example, if the number of comment contributors other than yourself is 30, the number of comment characters S increases by 60 characters. Therefore, the comment amount adjustment value is 60 characters.

  In the present embodiment, the comment amount adjustment value calculation unit 260 substitutes the number n of comment contributors other than itself for the function G3 (n), and calculates the comment amount adjustment value.

  The operation of the comment display server 200 of this embodiment will be described below with reference to FIG. FIG. 15 is a flowchart for explaining the operation of the comment display server of the third embodiment.

  The processing from step S1501 to step S1505 in FIG. 15 is the same as the processing from step S801 to step S805 in FIG.

  The comment display server 200 executes processing for displaying the shared comment from step S1506.

  Following step S1503, the comment display server 200 causes the comment acquisition unit 240 to extract comments posted by students other than students who are users of the terminal device 300 from the comment database 210 for N seconds (step S1506). Specifically, the comment acquisition unit 240 extracts a comment whose user ID does not match the user ID of the comment poster from the comments stored in the comment database 210 for N seconds.

  Subsequently, the comment amount adjustment value calculation unit 260 calculates the number n of comment contributors other than itself based on the comments extracted in step S1506 (step S1507). Subsequently, the comment amount adjustment value calculation unit 260 calculates the comment amount adjustment value G3 (n) (step S1508).

  Next, the comment display server 200 calculates the threshold value TH by the threshold value calculation unit 270 (step S1509). The threshold value TH in the present embodiment is given by the following Expression 3.

Threshold TH = min ((Smax−F (t) + G3 (n)), Smax) Equation 3
Therefore, specifically, the threshold calculation unit 270 determines whether or not Smax−F (t) + G3 (n)> Smax is satisfied.

  If Smax−F (t) + G3 (n)> Smax is satisfied in step S1509, the threshold value calculation unit 270 sets the maximum value Smax as the threshold value TH (step S1510). If Smax−F (t) + G3 (n)> Smax is not satisfied in step S1509, the threshold value calculation unit 270 sets the value of Smax−F (t) + G3 (n) as the threshold value TH (step S1511).

  The processing from step S1512 to step S1521 is the same as the processing from step S812 to step S821 in FIG.

  As described above, in this embodiment, the threshold value that is the upper limit of the number of characters of the shared comment to be displayed, using the elapsed time t from the start of the lesson and the number of comment contributors other than yourself as an index for determining the degree of student concentration. TH was provided. Therefore, in this embodiment, it is possible to display a shared comment having the number of characters corresponding to the degree of concentration of students who are users of the terminal device 300.
