If the OK key is pressed, control proceeds to step 420, and some input has been made, but if the input is not pressed, control proceeds to step 428.

  The user drags / drops the device icons to align the device icons in line with the actual electronic blackboard device. Referring to FIG. 1, since the electronic blackboard devices 200 and 300 are arranged in a horizontal row, as shown in FIG. 9, the user drags / drops each device icon so that the device icons 522 and 524 are also arranged in a horizontal row. (Step 428). When drag / drop is performed, CPU 110 changes the display of setting screen 510 to the state after the device icon has moved (step 430).

  When a priority is set for any of the electronic blackboard devices, the user drags / drops the priority icon 530 to the display position of the device icon corresponding to the electronic blackboard device desired to be set. Normally, the moving operation is invalid so that the editing operation is not hindered even if the image sheet is moved while the image editing operation is being performed on at least one of the plurality of electronic blackboard devices. It becomes. Therefore, even when a plurality of users operate a plurality of electronic blackboard devices, the user can edit an image without being interrupted by operations by other users. However, when priority is set for an electronic blackboard device, an operation for moving an image sheet displayed on the electronic blackboard device and an operation for editing an image displayed on another electronic blackboard device are performed simultaneously. In the case of being performed, the former operation is given priority. In other words, even if an operation to edit a display image is performed on another electronic blackboard device, if an operation is performed to move the image sheet on the electronic blackboard device having priority, the image sheets in the plurality of electronic blackboard devices as a whole Priority is given to the action of moving the. By setting the priority, the user can move the image sheet even when a plurality of people edit images simultaneously. When the user drags / drops the priority icon 530 to the display position of the device icon 522 (NO in step 428), the CPU 110 displays an icon indicating that priority is set for the electronic blackboard device 200 at the lower left of the device icon 522. It is displayed (step 432). When the process of step 432 is completed, control returns to step 416.

  When the user touches the device icon 522, a frame line 526 surrounding the device icon 522 is displayed (step 432). The display of the frame line 526 indicates that the icon is in a selected state. After the device icon 522 is selected, the user operates a numeric keypad (not shown) and inputs the display order of the electronic blackboard device 200. CPU 110 displays the input numerical value at the center of device icon 522 (step 432). Since “2” is displayed in the center portion of the device icon 522 and “1” is displayed in the center portion of the device icon 524 shown in FIG. 9, the display order of each electronic blackboard device is the number 1 for the electronic blackboard device 300. The electronic blackboard device 200 is second. That is, referring to FIG. 1, the image sheet is first displayed on the electronic blackboard device 300 and then displayed on the electronic blackboard device 200. Accordingly, in this case, the image sheet is displayed as if it is moving from right to left as viewed from the user facing each electronic blackboard device.

  When the input of settings for each electronic blackboard device is completed, the user presses the OK key 540 (YES in step 418). In step 420, the CPU 110 determines whether or not the input setting is correct. If the input content is not correct (NO in step 420), the CPU 110 displays an error notification (not shown) on the display screen 140 (step 426), and again determines whether or not an input from the user is detected (step 416). If the input content is correct (YES in step 420), the CPU 110 performs setting so that a display based on the input setting content is displayed on each electronic blackboard device (step 422). When the setting in step 422 is completed, the CPU 110 displays a setting completion notification (not shown) for notifying that the setting is completed on the display screen 140 (step 424), and the execution of this program ends.

<Sheet feeding>
Referring to FIGS. 2, 7-8, and 10-11 (particularly FIG. 10), a process in which the user moves an image sheet displayed on each electronic blackboard device (hereinafter referred to as “sheet feeding”). The operation of the information processing apparatus 100 when performing the above will be described.

  The user operates the setting screen 510 in FIG. 9 to set display conditions for each electronic blackboard device, and further specify an image sheet to be displayed (step 612). Based on the instruction from the user, the CPU 110 sets the content input by the user (step 422).

  Here, the CPU 110 creates display data of the image sheet based on the display condition of each electronic blackboard device and the setting related to the display start page of the designated image sheet. Referring to the setting screen 510, the electronic blackboard devices 200 and 300 are arranged in a horizontal row, and the display order of the electronic blackboard device 200 is set to 2 and the electronic blackboard device 300 is set to 1st. In this case, for example, the first page of the image sheet is first displayed on the electronic blackboard device 300 and then displayed on the electronic blackboard device 200. That is, the image is displayed as if it moved from the right to the left toward the electronic blackboard device. In accordance with the setting of such display conditions, the CPU 110 sets the image sheet of the display start page as the first sheet, and the sheets constituting the designated image sheet are sequentially from the left as the first sheet, the second sheet, and so on. Display data arranged in order.

  The CPU 110 transmits a signal instructing to display the first sheet (cover page) which is the display start page of the designated image sheet to the electronic blackboard device 300 (step 614). In response to receiving the instruction signal, the electronic blackboard apparatus 300 displays a cover page on the touch panel display 310 as shown in FIG. 11A (step 616).

  When the user flicks the image sheet displayed on the electronic blackboard device 300 from right to left (step 618), the detection unit 332 of the electronic blackboard device 300 detects the user's flick (step 620), and the CPU 352 performs the sheet feeding operation. A signal notifying that it has been detected is transmitted to the information processing apparatus 100 (step 620).

  In step 440, the CPU 110 determines what kind of user operation is notified by the signal received from the electronic blackboard device 300. Referring to FIG. 8, when it is determined that the content of the user operation is sheet feeding, CPU 110 determines that there is no sheet being edited (NO in step 462), and no pinning setting is set (step In response to NO at 466, the CPU 110 transmits a signal instructing the electronic blackboard devices 200 and 300 to send the image sheet (step 470).

  The display data displayed on each electronic blackboard device is configured so that each sheet is continuously arranged from left to right starting from the image sheet (cover page) of the cover start page. In response to the user flicking from right to left, the CPU 110 reads the display data from the left to the right at regular intervals, and controls the electronic blackboard device 300 to sequentially display the read images. Therefore, referring to FIG. 11B, the electronic blackboard apparatus 300 displays the second image sheet (one page) so as to slide from the first image sheet (cover page) (step 622). ). Similarly, the first blackboard apparatus 200 slides and displays the first image sheet (cover page) as if it has moved from the electronic blackboard apparatus 300 (step 624). The speed at which the image slides is determined by the speed of flicking, and the amount of sliding is determined by the flicked distance. 11B, the electronic blackboard device 200 displays the first image sheet (cover page), and the electronic blackboard device 300 displays the second image sheet (one page). 11 (c).

  Since the priority is set for the electronic blackboard device 200, if the electronic blackboard device 200 detects a sheet feeding operation while editing the image sheet displayed on the electronic blackboard device 300, the sheet is displayed. The feed is executed with priority. In this case, the information processing apparatus transmits a signal and display data instructing both the electronic blackboard apparatuses 200 and 300 to perform sheet feeding. By receiving the signal or the like, sheet feeding is also executed in the electronic blackboard device 300 that has been edited.

<Action and effect>
When the user flicks an image displayed on the electronic blackboard device, the image moves according to the flick operation. The direction, speed, and amount of movement correspond to the flick performed by the user. This movement is performed by the electronic blackboard devices 200 and 300, and the user can display an image in a wider range than when one electronic blackboard device is used. Furthermore, the image displayed on the electronic blackboard device can be easily changed by moving the image by flicking. Since the image sheet is displayed as if it is moving between the electronic blackboard devices in sheet units, the user can cause the plurality of electronic blackboard devices to execute sheet feeding by an intuitive operation.

  The display system described above includes one information processing device and two electronic blackboard devices. Therefore, this display system can be realized even with a stand-alone PC.

[First Modification]
<Sheet feeding when pinning is set>
In the above operation, both of the image sheets displayed on the electronic blackboard devices 200 and 300 are slid and displayed. However, the display of some image sheets is fixed, that is, with respect to some electronic blackboard devices. With the pinning setting set, sheet feeding for sliding other image sheets may be performed. The display system according to the first modification includes an electronic blackboard device 400 in addition to the electronic blackboard devices 200 and 300. Since the configuration of the electronic blackboard device 400 is the same as that of the electronic blackboard devices 200 and 300, description thereof will not be repeated here.

<Operation>
Referring to FIG. 2, FIG. 7-8, and FIG. 12-13 (particularly FIG. 12), when pinning setting is set for some electronic blackboard devices, the user is displayed on each electronic blackboard device. The operation of the information processing apparatus 100 when performing the process of moving the image sheet (hereinafter also referred to as “sheet feeding”) will be described.

  Referring to FIG. 12, the user operates a setting screen (not shown) displayed on information processing device 100 to set display conditions for each electronic blackboard device, and further specifies an image to be displayed (step). 612). In this modification, the display order of each electronic blackboard device is set so that the electronic blackboard device 400 is first, the electronic blackboard device 300 is second, and the electronic blackboard device 200 is third. The first image sheet displayed on each electronic blackboard device is the first image sheet (table of contents page) for the electronic blackboard device 200, and the second image sheet (one page) for the electronic blackboard device 300. The electronic blackboard device 400 is set to display the third image sheet (2 pages).

  In response to receiving a signal for notifying the setting input by the user, the CPU 110 sets the contents of the input and creates display data (step 422). This display data consists of the first image sheet (table of contents page), the second image (1 page), the third image (2 pages), and so on. Are arranged in a row. Since the display order of the electronic blackboard device 400 is No. 1, when sheet feeding is performed, the CPU 110 operates to read the display data from the left to the right at regular intervals and display the display data on each electronic blackboard device.

  The CPU 110 transmits a signal instructing each electronic blackboard device to display the designated image sheet (step 614). In response to receiving this instruction signal, referring to FIG. 13A, the electronic blackboard device displays the table of contents page, the electronic blackboard device 300 displays the first page, the electronic blackboard device 400 displays the second page, Each is displayed on each touch panel display (steps 632 to 636).

  The user turns on an input pen pinning setting key (not shown) and touches the screen displayed on the touch panel display 210 of the electronic blackboard device 200 with the input pen (step 638). The detection unit 232 of the electronic blackboard apparatus 200 detects a user operation for instructing pinning setting, and the CPU 252 transmits a signal notifying the detection to the information processing apparatus 100 (step 640). CPU 110 transmits a signal instructing to fix the display of the currently displayed image sheet (table of contents page) to electronic blackboard apparatus 200 (step 446). Hereinafter, fixing the display of the image sheet being displayed may be referred to as “locking”.

  The CPU 252 fixes the display of the image page of the table of contents page, and further displays a pinning setting icon 550 indicating that the pinning setting is performed on the upper right of the display screen (step 642). The image sheet of the table of contents page is kept locked until the pinning setting icon 550 is touched with the input pen.

  Referring to FIG. 13B, the user flicks the image sheet displayed on electronic blackboard apparatus 300 from right to left, and sends the image sheet (step 644). The detection unit 332 of the electronic blackboard device 300 detects the flick operation, and the CPU 352 transmits a signal notifying that the flick operation has been detected to the information processing apparatus 100 (step 646). In response to receiving this signal, the CPU 110 sends a signal for instructing to display the read data while shifting the display data created in step 422 from left to right at regular intervals, and the electronic blackboard device 300 and the data. It transmits to 400 (step 468). In response to receiving this signal or the like, the electronic blackboard apparatus 300 sends the first image sheet and displays the second image sheet (step 648). The electronic blackboard device 400 sends the second page image sheet and displays the third page image sheet (step 650). While the sheet feeding in steps 648 and 650 is being executed, the image board of the index page continues to be displayed on the electronic blackboard device 200.

<Action and effect>
When a desired image sheet is touched with an input pen with the pinning setting function turned on, the user can fix the display of the image sheet. Thereafter, the user can feed another image sheet while fixing the display of the image sheet. Therefore, when there is a sheet to be displayed on the electronic blackboard device, the user can edit the other image sheet while the image sheet is displayed by setting the image to be pinned. .

[Second Modification]
<Sheet feeding during group setting>
Some of the plurality of electronic blackboard devices may be grouped together into one group, and sheet feeding may be performed on the electronic blackboard devices belonging to the group in units of the number of electronic blackboard devices constituting the group. . The display system according to the second modification includes an electronic blackboard device 500 in addition to the electronic blackboard devices 200-400. Since the electronic blackboard device 500 has the same configuration as the electronic blackboard device 200-400, the description thereof will not be repeated.

<Operation>
14-16, since there are four electronic blackboard devices in this modification, four device icons 662-668 are displayed in setting area 520 of setting screen 510 shown in FIG. The user drags / drops these device icons to match the actual arrangement of each electronic blackboard device. As shown in FIG. 16, the electronic blackboard devices 200-500 are arranged so that there are two vertically and two horizontally, so that the device icons 662-668 are also set to have the same arrangement. The display order of each electronic blackboard device is set so that the electronic blackboard device 200 is fourth, the electronic blackboard device 300 is third, the electronic blackboard device 400 is second, and the electronic blackboard device 500 is first. Further, the user sets priority for the electronic blackboard device 400.

  In the setting screen 510 of FIG. 14, when an operation for surrounding a desired device icon is performed by dragging a cursor or the like, the electronic blackboard device corresponding to the device icon can be set to the same group. The user drags a cursor or the like so as to surround the device icons 666 and 668. In response to the drag operation being executed, a frame line 678 is displayed around the device icons 666 and 668, and a group display 672 indicating that the electronic blackboard devices 400 and 500 are included in the group 1 is displayed. The When the same operation is performed on the device icons 662 and 664, a frame line 676 and a group display 670 indicating that the electronic blackboard devices 200 and 300 are included in the group 2 are displayed.

  Which group each electronic blackboard device belongs to is automatically determined by the display order of the electronic blackboard device. Since the group display 672 includes the electronic blackboard device 500 having the first display order, “group 1” is automatically displayed when a drag operation surrounding the device icons 400 and 500 is performed. Similarly, the group display 670 indicates “a group 2” because it indicates a group formed by a collection of electronic blackboard devices that do not belong to the group 1. When the display order of each electronic blackboard device is not set, a message (not shown) “Please enter a group name” is displayed on the group display, and the user operates the operation device 150 shown in FIG. And enter the group name.

  When the user presses the OK key 540, display conditions for each electronic blackboard device are set. The user further designates an image sheet to be displayed on each electronic blackboard device (step 612 in FIG. 15). The CPU 110 sets these input contents and creates display data. Since each electronic blackboard device is set in the arrangement and display order as shown in FIG. 14, the CPU 110 arranges the display data so that each image sheet is arranged in two horizontal rows so that the display order decreases from top to bottom. Specifically, the left side of the first row is the first image sheet, the right side is the second image sheet, the left side of the second row is the third image sheet, and the right side is the fourth image sheet. The image sheets are arranged so as to become. Furthermore, since there are four electronic blackboard devices in this modification, the fourth image sheet is displayed on the electronic blackboard device 500 having the highest display order, and the third image sheet is displayed on the electronic blackboard device 400 having the second display order. The display data is configured so that is displayed first.

  In response to the CPU 110 transmitting a signal instructing to display the first image to be displayed to each electronic blackboard device, the touch panel display of each electronic blackboard device has an image sheet as shown in FIG. Is displayed (steps 682 to 688 in FIG. 15).

  When the user flicks the image sheet displayed on the electronic blackboard device 400 from the bottom to the top (step 690 in FIG. 15), the detection unit (not shown) of the electronic blackboard device 400 detects the flick operation, and the electronic blackboard. A CPU (not shown) included in the control device of the device 400 transmits a signal notifying that it has been detected to the information processing device 100 (step 692 in FIG. 15). In response to receiving this notification signal, CPU 110 transmits a signal and display data for instructing each electronic blackboard device to feed the sheet (step 468 in FIG. 15).

  Each electronic blackboard device displays the transmitted display data. Here, since the electronic blackboard devices 200 and 300 and the electronic blackboard devices 400 and 500 are set in the same group, the image sheets displayed on each electronic blackboard device slide two by two. The CPU 110 reads the display data arranged in two horizontal rows from the top to the bottom and displays them on each electronic blackboard device. For example, in the electronic blackboard device 200, the image sheet displayed next to the image sheet of the first page is the third page instead of the second page. Similarly, on the electronic blackboard device 400, the image sheet of the fourth page is displayed next to the image sheet of the second page. The CPU 110 transitions the display of each electronic blackboard device to the state of FIG. 16C through the display as shown in FIG. 16B (step 694-702 in FIG. 15).

  Even when the group is set, the sheet feeding operation performed in the electronic blackboard apparatus having priority is prioritized over other user operations. When the sheet feeding operation is detected in the electronic blackboard device 400, the sheet feeding is preferentially executed even when the image sheet is being edited in another electronic blackboard device.

<Action and effect>
If several electronic blackboard devices are set as a group, sheet feeding can be performed in units of the number of electronic blackboard devices constituting the group. Therefore, an image can be displayed more effectively than when the sheets are fed one page at a time. If the group classification is devised, a wide variety of displays can be realized. Such a display method is more effective when displaying an image at a large place, such as an advertisement display at a station or airport, a presentation at a large conference hall, etc., as well as a lesson at school.

  In this modification, priority may be set not for individual electronic blackboard devices but for the entire group. Referring to FIG. 14, since the priority is set for the electronic blackboard device 400 belonging to group 1, not only the electronic blackboard device 400 but also the electronic blackboard device 300 detects the sheet feeding operation. The sheet feeding operation is executed in preference to the operation for editing the image sheet.

  Although the display system according to the present embodiment is used in a class or the like, the situation to be used is not limited to a class. For example, the present display system can be used for meetings and presentations. The size and number of information processing devices and electronic blackboard devices are not limited. Furthermore, as long as it is connected, the information processing device and the electronic blackboard device may be installed in a remote place. By adopting such a configuration, the present system can be used for a conference that is relayed to a remote place.

  The display screen 140 and the operation device 150 of the information processing apparatus 100 may be configured by an integrated touch panel display. Alternatively, the information processing apparatus 100 may be incorporated in any electronic blackboard apparatus. With such a configuration, not only image display but also control of other electronic blackboard devices can be performed with one electronic blackboard device, and the management burden can be reduced.

  In the above embodiment, the priority right icon 530 shown in FIG. 9 is set by dragging / dropping to the device icon corresponding to the desired electronic blackboard device. However, the priority right setting is not limited to such a method. . For example, as in the pinning setting, when a priority setting key is provided in advance on the input pen and a desired device icon is touched with the key turned on, the priority is set for the corresponding electronic blackboard device. It may be configured as follows. On the contrary, the pinning setting may be configured such that a pinning setting icon is displayed on the display unit of the electronic blackboard device and the pinning setting is executed by dragging / dropping the icon to a predetermined position.

  In the above embodiment, the display order of the electronic blackboard device is input using the numeric keypad, but the display order setting is not limited to this method. For example, the display order may be set in the order of device icons in which operations for touching the device icons twice in succession are executed. Referring to FIG. 9, when the device icon 524 is double-touched in a state where the display order is not set on both of the electronic blackboard devices 200 and 300, the electronic blackboard device 300 is set first. In order to change the order, if the device icon that has been set is double-touched, the icon is not set, and the display order of other set blackboard devices is increased (in FIG. The display order of 200 is advanced first.) With such a configuration, it is not necessary to provide a numeric keypad in the information processing apparatus, and the display order can be set with a simpler operation.

  In the above-described embodiment, it is assumed that the sheet feeding of the electronic blackboard device having the priority right is executed in preference to the editing operation for other electronic blackboard devices, but the scope of the effect of the priority right is not limited to this. For example, when sheet feeding in the opposite direction is executed at the same time, sheet feeding executed by the electronic blackboard apparatus having priority may be executed with priority. Alternatively, when any user operation such as editing and sheet feeding is detected in the electronic blackboard device having priority, the other electronic blackboard device may not be able to perform any operation. With such a configuration, for example, it is possible to prevent the student from operating the image sheet while the teacher is performing sheet feeding and editing.

  In the above embodiment, when the group setting is performed, the group number is automatically displayed according to the display order of the electronic blackboard device belonging to each group. However, the group name display method is not limited to such a form. For example, numbers are automatically assigned as group 1, group 2,... In the order in which the group settings are made, and the group name desired to be changed by touching the group display with an input pen or the like. It is good also as a structure which enables this change. With such a configuration, the group name is automatically displayed even when the display order of each electronic blackboard device is not set. Furthermore, when it is desired to change the group name, the user can change the group name by touching the group display with an input pen or the like and operating the operation device 150.

[Second Embodiment]
In the first embodiment, a plurality of electronic blackboard apparatuses 200-400 are controlled by one information processing apparatus 100.

However, the other processes are the same as those in FIG.

  In step 612, the user instructs the information processing apparatus 700 to set display conditions for each electronic blackboard device and to specify an image sheet to be displayed. In step 620, when the electronic blackboard apparatus 900 detects the sheet feeding operation, in step 722, the information processing apparatus 700 transmits a display instruction signal and display data to the information processing apparatus 800 and the electronic blackboard apparatus 900. The electronic blackboard device 900 sends the image sheet of the cover page and displays the first image sheet (step 622).

  In response to the signal transmitted by the information processing apparatus 700 in step 722, the information processing apparatus 800 transmits an instruction signal and display data to the electronic blackboard apparatus 1000. In response to the instruction signal, the electronic blackboard apparatus 1000 displays the image sheet of the cover page indicated by the display data (step 624).

<Action and effect>
According to the display system according to the present embodiment, each electronic blackboard device is controlled by each information processing device. When there are a large number of electronic blackboard devices, the configuration of this embodiment reduces the burden on the information processing devices, rather than the configuration of controlling all the electronic blackboard devices with a single information processing device. it can.

  In this embodiment, a display system including two pairs of combinations of an information processing device and an electronic blackboard device is configured. However, any number of pairs may be included in the display system. When configured to include a large number of pairs, a large-scale display system can be configured without imposing an excessive burden on the main information processing apparatus that performs control.

  Embodiments obtained by appropriately combining the techniques disclosed above are also included in the technical scope of the present invention.

  (1) The information processing apparatus 100 according to the first aspect of the present invention is connected to a plurality of electronic blackboard apparatuses 200 and 300. The information processing apparatus 100 includes a storage unit for storing a plurality of image sheets in association with the display order of the image sheets, and display of image sheets displayed on each of the plurality of electronic blackboard apparatuses 200 and 300. The setting means for setting the relationship between the order and the image sheet displayed on one of the plurality of electronic blackboard devices 200 and 300 among the plurality of image sheets stored in the storage means are designated. In response, the image sheet to be displayed on each electronic blackboard device is determined based on the setting by the setting means and the display order of each image sheet stored in the storage means, and is displayed on each electronic blackboard device. Display control means.

  The information processing apparatus 100 stores a plurality of image sheets in association with the display order, and sets the relationship of the display order of the image sheets displayed on the plurality of electronic blackboard apparatuses 200 and 300. Further, when an image to be displayed on one of the electronic blackboard devices is designated, the information processing apparatus 100 determines an image sheet to be displayed on each electronic blackboard device based on the display order and the settings. Therefore, by using this information processing apparatus 100, the user can arbitrarily set how to display a plurality of image sheets on a plurality of electronic blackboard apparatuses, and can effectively display a plurality of sheets. Furthermore, if an operation for changing the display is performed, an image sheet corresponding to the change is displayed on each electronic blackboard device. If the user presets the display order of the plurality of image sheets and the relationship between the display orders, the user can effectively display the plurality of image sheets on each electronic blackboard device with a simple operation.

  (2) Preferably, the information processing apparatus 100 inputs information indicating whether or not to fix the display of an image displayed on the electronic blackboard device to at least one of the plurality of electronic blackboard devices 200-400. And a fixed information storage means for receiving and storing the image sheet, wherein the display control means designates an image sheet to be displayed on one of the plurality of electronic blackboard devices among the plurality of image sheets stored in the storage means. In response to this, a plurality of electronic blackboard devices other than the electronic blackboard device that stores the fixed display by the fixed information storage unit based on the setting by the setting unit and the display order of each image sheet stored in the storage unit Means for determining an image sheet to be displayed on the electronic blackboard apparatus and displaying the image sheet on each electronic blackboard apparatus.
