  FIG. 15 is a diagram illustrating the minutes data 160. The product generator 64 may generate the minutes data 160 in addition to the product data.

  The minutes data 160 is data including product data information 162 and a list 164. The list 164 includes, for example, at least the shared data associated with the worksheet corresponding to the product data information 162, the user who generated the shared data, and the date and time of generation. By generating such minutes data 160, the product generator 64 can confirm the content of the product data later.

  FIG. 16 is a diagram illustrating a screen of the terminal device 20 displaying a user interface image (input image 172) for inputting data. When a predetermined operation is performed by the terminal device 20 of a specific user, the forced input control unit 68 displays a user interface image for inputting data on the screen of each terminal device 20.

  For example, suppose that the forced input button 170 on the main image 130 is operated while the main image 130 including the work area 136 is displayed on the screen of the terminal device 20 of the specific user. In this case, the forced input control unit 68 causes a user interface image (input image 172) for inputting text data to be pop-up displayed on the screen of the terminal device 20 of another user. In this case, the forced input control unit 68 may be configured not to operate an image other than the input image 172 on the screen of the terminal device 20 of another user.

  The user of each terminal device 20 can input information such as text data into the input image 172 on which the pop-up is displayed. Then, when data is input to the user interface image (for example, the input image 172), the shared data management unit 58 registers the input data as new shared data. Thus, for example, when the teacher or the like presents the question sentence, the forced input control unit 68 can cause the student to input an answer.

  FIG. 17 is a diagram illustrating a display example of the tag image 174. The shared data management unit 58 may display the input data by pop-up display of the input image 172 in a display format different from other shared data. For example, the shared data management unit 58 may paste a single-color rectangular sticky note image 174 such as a sticky note on top of the shared data, and display the data input to the input image 172 on the sticky note image 174. . This allows the shared data management unit 58 to recognize the data displayed on the tag image 174 as a comment or the like on the shared data.

  Further, the forced input control unit 68 may display the input image 172 in a pop-up display on the screen of each terminal device 20 in a state where the main image 130 including the product display area 140 is displayed. In this case, the product generator 64 combines the input data with the product data. For example, the product generation unit 64 synthesizes a tag image 174 in which a comment is displayed on the top of the product data. As a result, the product generation unit 64 can cause the data displayed on the tag image 174 to be recognized as a comment or the like on the product data.

  FIG. 18 is a diagram illustrating a functional configuration of the time management unit 70. FIG. 19 is a diagram showing the time management area 138. FIG. 20 is a diagram illustrating an example of a change in the display of the time management area 138. FIG. 21 is a diagram illustrating a time management area when the first time mark 186 is moved.

  The time management unit 70 includes a timeline display control unit 82, a log display control unit 84, a first time display control unit 86, and a second time display control unit 88.

  The timeline display control unit 82 displays a timeline bar 180 and a current time line 182 in the time management area 138 as shown in FIG. The timeline bar 180 represents a time in a predetermined time range including the current time. For example, a timeline bar 180 shown in FIG. 19 indicates a time in a range from 8:50 to 10:20. The timeline display control unit 82 is not limited to such a time range, and may represent any time range.

  The current time line 182 indicates a position on the timeline bar 180 corresponding to the current time. The current time line 182 shown in FIG. 19 indicates 9:55 as the current time.

  The timeline display control unit 82 relatively moves the display range of the timeline bar 180 and the position of the current timeline 182 over time. For example, as in the transition from A to B in FIG. 20, the timeline display control unit 82 moves the current timeline 182 over time with the display range of the timeline bar 180 fixed. Further, for example, as in the transition from B to C in FIG. 20, the timeline display control unit 82 may change the display range of the timeline bar 180 with the current timeline 182 fixed.

  As shown in FIG. 19, the log display control unit 84 displays the thumbnail image 184 of the log of the terminal image at a position on the timeline bar 180 corresponding to the generation time of the log of the terminal image. For example, the log display control unit 84 displays the thumbnail image 184 of the terminal image at the time when the content is updated. Note that the log display control unit 84 displays the thumbnail image 184 of the terminal image of the specified one terminal device 20. In addition, the log display control unit 84 may switch the designation of the terminal device 20 by a user operation. Further, the log display control unit 84 may display the thumbnail images 184 of the terminal images of the plurality of terminal devices 20 in a mixed manner.

  Further, the log display control unit 84 may display the thumbnail image 184 of the shared data at a position on the timeline bar 180 corresponding to the generation time of the log of the terminal image. For example, the log display control unit 84 causes the thumbnail image 184 of the shared data to be displayed at the time when the content is updated. Note that the log display control unit 84 switches between displaying the thumbnail image 184 of the terminal image and displaying the thumbnail image 184 of the shared data by an operation of the user.

  The first time display control unit 86 controls the display position of the first time mark 186, as shown in FIG. The first time mark 186 specifies the time (first time) of the log of the terminal image displayed in the reproduction area 134. The first time display control unit 86 displays the first time mark 186 at the current time position on the timeline bar 180 during normal times. That is, the first time display control unit 86 specifies the current time as the first time in normal times. Therefore, in the reproduction area 134, the terminal image at the current time is displayed in the normal state.

  Here, the first time display control unit 86 moves the first time mark 186 to a position on the timeline bar 180 corresponding to a past time, as shown in FIG. When the first time mark 186 moves to a position corresponding to a past time, the terminal image display control unit 56 acquires the terminal image log at the first time from the data storage unit 46 and It is displayed in the reproduction area 134 on the screen. Thereby, the terminal image displayed in the past is displayed in the reproduction area 134.

  The second time display control unit 88 controls the display position of the second time mark 188. The second time mark 188 specifies the time (second time) of the log of the shared data to be displayed in the work area 136. The second time display control unit 88 displays the second time mark 188 at the current time position on the timeline bar 180 during normal times. That is, the second time display control unit 88 specifies the current time as the second time in normal times. Therefore, the shared data at the current time is displayed in the work area 136 in the normal state.

  Here, the second time display control unit 88 moves the second time mark 188 to a position corresponding to a past time on the timeline bar 180 in response to a user operation. When the second time mark 188 moves to a position corresponding to the past time, the shared data display control unit 62 acquires the log of the shared data at the second time from the data storage unit 46, and It is displayed in the work area 136 on the screen. Thereby, the shared data displayed in the past is displayed in the work area 136.

  FIG. 22 is a diagram illustrating a functional configuration of the progress management unit 72. The progress management unit 72 includes a target time input unit 92, a target display control unit 94, and a warning control unit 96.

  The target time input unit 92 receives an input of a target time for completing the generation of the product data at the start of the project. For example, the target time input unit 92 receives an input of the target time from the terminal device 20 of the specific user. The target display control unit 94 displays information indicating the target time at a position corresponding to the target time on the time line bar 180 in the time management area 138. The warning control unit 96 causes each terminal device 20 to notify a warning when the product data is not generated.

  FIG. 23 is a diagram illustrating the time management area 138 when the input of the target time of the completion of the generation of the product data is received.

  When generating a plurality of product data in one project, the target time input unit 92 receives an input of a target time for each of the plurality of product data to be generated. For example, in the case of the example of FIG. 23, the target time input unit 92 receives an input of 9:25 as the target time for the first product data, and sets the target time for the second product data as the target time. The input at 9:50 is accepted.

  The target display control unit 94 displays information indicating the target time at a position corresponding to the target time on the timeline bar 180 for each product data. For example, in the case of the example of FIG. 23, the target display control unit 94 displays the first target icon 192-1 on the first product data at the position of 9:25 on the timeline bar 180. Further, the target display control unit 94 displays the second target icon 192-2 on the second product data at the position of 9:50 on the timeline bar 180. Then, the target display control unit 94 moves the first target icon 192-1 and the second target icon 192-2 displayed in this manner in accordance with the transition of the time position indicated by the timeline bar 180.

  FIG. 24 is a diagram illustrating the time management area 138 when the current time reaches a predetermined time before the target time. The warning control unit 96 causes each terminal device 20 to notify a warning when the product data is not generated even when the current time reaches a predetermined time before the target time.

  For example, in the example of FIG. 24, the warning control unit 96 determines that the current time has reached 9:20, which is 5 minutes before the target time, and the corresponding first product data is generated. If not, a warning that the first product data has not been generated is notified. For example, the warning control unit 96 may give a notification by voice or may give a warning by blinking the first target icon 192-1. Thereby, the warning control unit 96 can make the user who is a participant of the project recognize that the time is approaching the target time for generating the product data.

  Note that the warning control unit 96 does not notify a warning when the product data is generated. If the product data is generated after the warning is notified, the warning control unit 96 stops the notification of the warning.

  FIG. 25 is a diagram illustrating the time management area 138 when the product data is not generated even if the current time exceeds the target time. Further, it is assumed that the time advances and the current time exceeds the target time. The target display control unit 94 changes the display format of the information indicating the target time when the product data is not generated even when the current time exceeds the target time.

  For example, in the example of FIG. 25, when the current time exceeds 9:25, which is the target time, and the first product data has not been generated yet, the target display control unit 94 The display color or shape of the first target icon 192-1 corresponding to the first product data is changed. Thereby, the target display control unit 94 can make a user who is a participant of the project recognize that the product data has not been generated even after the generation target time.

  Note that the target display control unit 94 does not change the display format when the product data is generated. When the product data is generated after the display format is changed, the target display control unit 94 restores the display format.

  FIG. 26 shows time management when the product data is not generated even when the current time exceeds the target time, and when the target time is out of the time range represented by the timeline bar 180. FIG. 14 is a diagram showing an area 138. Further, it is assumed that the time is advanced and the target time is out of the time range represented by the timeline bar 180. The target display control unit 94 determines that the product data is not generated even if the current time exceeds the target time, and that the target time is outside the time range represented by the timeline bar 180. , The information indicating the target time is displayed at a position corresponding to the earliest time in the timeline bar 180.

  For example, in the example of FIG. 26, the timeline bar 180 represents the time range from 9:40 to 11:00, and the target time of the completion of the generation of the first product data is 9:25. Suppose it was minutes. In this case, if the first product data has not yet been generated, the target display control unit 94 sets the first product data at a position corresponding to 9:40 which is the oldest time on the timeline bar 180. The first target icon 192-1 corresponding to the data is displayed. As a result, even when the target time is outside the time range represented by the timeline bar 180, the target display control unit 94 generates product data for the user who is a participant of the project. It can be recognized that it has not been done.

  Note that the target display control unit 94 does not display information indicating the target time when the product data is generated and the target time is outside the time range represented by the timeline bar 180. When the product data is generated after the target time is out of the time range represented by the timeline bar 180, the target display control unit 94 deletes the display of the information indicating the target time.

  FIG. 27 is a diagram showing the time management area 138 on which the scheduled period bar 194 is displayed. When the target display control unit 94 receives the target time of the completion of the generation of the product data, the target terminal device 20 gives the respective terminal devices 20 a scheduled period indicating the period from the project start time to the latest target time in the timeline bar 180. The bar 194 may be displayed.

  For example, in the example of FIG. 27, the start time of the project is 9:00, and the latest target time is 9:50. Therefore, the target display control unit 94 displays the scheduled period bar 194 indicating the period from 9:00 to 9:50 in the timeline bar 180. Thereby, the target display control unit 94 can make the user who is a participant of the project recognize the remaining time of the project.

  FIG. 28 is a diagram illustrating the time management area 138 when the product data that is to be generated later is generated first. When a plurality of product data is generated in one project, the product data that is to be generated later may be generated first. In this case, the target display control unit 94 calculates the remaining time of the generation period assigned to the product data to be generated later, to the product data to be generated earlier, which has not been generated yet. Change in addition to the target time of generation completion. Then, the target display control unit 94 causes the timeline bar 180 to display, at the position of the changed target time, information indicating the target time of the deliverable data that is to be generated first.

  For example, it is assumed that the target time of the completion of the generation of the first product data is 9:25 and the target time of the completion of the generation of the second product data is 9:50. Then, it is assumed that the generation of the second product data is completed at 9:15. In this case, the target display control unit 94 sets the remaining time (25 minutes from 9:25 to 9:50) of the generation period assigned to the second product data to the generation of the first product data. In addition to the target time of completion, the target time of completion of generation of the first product data is changed to 9:50 (9: 25 + 25). Then, the target display control unit 94 causes the first target icon 192-1 to be displayed at a position of 9:50 on the timeline bar 180.

  Accordingly, the target display control unit 94 can appropriately change the target time of the completion of the generation of the product data even when the product data is generated in a different order from the schedule.
