[Sequence of cooperation between devices]
FIG. 5 is a sequence diagram for explaining the cooperative operation between the devices shown in FIG. Here, a cooperative operation between the information terminal 200 and the information processing server 100 and the scanner of the MFP 600 as an input device and the projector 400 as an output device is shown.
The information terminal 200 notifies the information processing server 100 of a command instruction for cooperation processing via an intermediary device (not shown). Receiving the command instruction, the information processing server 100 executes job processing necessary for cooperation processing by the command analysis unit 112 and the job management unit 113 described with reference to FIG.

Here, an example in which an image read by the scanner of MFP 600 is projected by projector 400 is shown.
The information processing server 100 sends a job request to start reading to the MFP 600. Receiving it, the MFP 600 returns a job response to the information processing server 100 and performs a reading process with the scanner.
Next, the information processing server 100 sends a device status acquisition job request to the MFP 600. The MFP 600 returns the read operation status to the information processing server 100 as a job response.

After that, the information processing server 100 makes a job request for image data acquisition to the MFP 600 if the reading completion status can be acquired. In contrast, the MFP 600 returns the read image data to the information processing server 100 as a job response.

To do.

[Create history data table]
FIG. 6A is a diagram illustrating an example of a history data table created and stored by the information processing server 100.
Document and image data handled in the conference are stored in the conference information database 119 shown in FIG. Therefore, when each device in the conference support system performs processing for a document / image, it is performed via the information processing server 100.

  In view of this, in the information processing server 100, every time a device accesses a document and an image, the history of the conference ID, date / operator (user), document / image file path, and what operation / Record the processing. That is, the device name, processing content, and display time in the case of display processing are recorded as to whether or not to be replayed.

Then, a history data table as shown in FIG. 6A is created and stored in the history information database 117 shown in FIG.
When projecting a document with the projector 400, both a history of the projected document (history ID = 00007 in FIG. 6A) and a history of projecting the image of each page (history ID = 00008 to 00001) remain. Therefore, the projector 400 is notified of when the projection of the document is started and when the image of each page is projected. Whether the projection history is a document or an image can be determined by the extension of the file path.

  The “document” used here is a data file including a plurality of pages, and the data cannot be displayed by turning the page on the projector. The actual display content is not limited to a document, but is referred to as a “document” regardless of whether an image is included or only an image. “Image” is data for each page that can be displayed by the projector, and the actual display content is not limited to the image only. ".

As shown in FIG. 6A, in the history of projecting (displaying) or saving an image on the electronic blackboard 500 (history ID: 00001, 00003, 00001, 01000), the time (seconds) when the image was projected is “displayed” Record as “Time”.
In the history of projecting an image by the projector 400 (history ID: 00002, 00008 to 00001), the time (seconds) for projecting the image is recorded as “display time”. However, “display time” is not recorded in the history of projecting the document (history ID: 00007).

This is because “projection of a document” merely confirms the entire image to be projected, and actual projection sequentially projects images sent from the information processing server 100 for each page. The image of the first page is sent from the information processing server 100 simultaneously with the document. Therefore, the history of the date and time of history ID: 00007 and 00008 is the same.
In the information processing server 100, in the access from each device to the document / image, for the output access to the projector 400 or the electronic blackboard 500 as the display device, the replay target of the history data table shown in FIG. ".

FIG. 7 is a flowchart showing the flow of history data table recording processing by the information processing server 100.
Let N be the last history ID in the created history data table (N = 00013 in the example of FIG. 6A). The information processing server 100 starts the process shown in FIG. 7 every time there is an access request from the information terminal 200. In step S7.1, the history ID is set to N + 1, and in step S7.2, the history ID is set as a new N, and the next record is recorded in the history.
・ Conference ID ・ Date ・ Operator ・ Document (image) file path ・ Device name (ID) ・ Processing content

The conference ID is an identification code registered in advance by the organizer in the information processing server 100 in order to identify the conference, or automatically generated by the information processing server 100 at the start of the conference.
The date and time are the month / day, hour, minute, and second when an access request is received from the information terminal 200.
The operator searches a correspondence table between pre-registered conference participant IDs and device-specific information from device-specific information (for example, Mac address) notified from the accessed information terminal 200, and The participant who hit is the operator.

The document (image) file path corresponds to the file name to be accessed.
The device name is an information device that inputs or outputs data of a specified file, and is an ID that identifies one of the projector 400, the electronic blackboard 500, and the MFP 600 in the embodiment shown in FIG.
The processing contents are processing names such as projection (display), saving an image on the electronic blackboard, scan input, print output, file upload, and the like.

In the next step S7.3, the information processing server 100 determines whether or not the processing content is “projection”. When it is determined that the processing content is “projection”, the process proceeds to step S7.4 and is displayed in the history ID = N. After recording the time, the process proceeds to step S7.5. If the information processing server 100 determines in step S7.3 that it is not “projection”, it skips step S7.4 and proceeds to step S7.5.
This “projection” includes “display”, and “display time” includes “projection time”.

With this process, the information processing server 100 records the display time in the history when the electronic blackboard 500 or the projector 400 projects a document or image. Therefore, when the projection of the document from the electronic blackboard 500 is finished, and when the projection of the image of each page from the projector 400 is finished, the information processing server 100 is notified of how long the document or image has been projected. do that for me.
Thereafter, in step S7.5, the information processing server 100 determines whether or not it is a replay target. If it is a replay target, it is recorded as a “target” of replay in step S7.6, and if it is not a replay target, it is recorded as a “non-target” of replay in step S7.7. Then, the process shown in FIG. 7 ends.

This history data table recording process by the information processing server 100 is a function of the history information creating / recording means described above.
Then, the processing of steps S7.5 to S7.7 by the information processing server 100 determines whether the output document or image information is a replay target or not when the history information is created, and adds it to the history information. This is a function of the replay target discrimination means.
In this way, the information processing server 100 updates the history data table every time there is an access request from the information terminal 200, and the display time necessary for executing the replay processing there, and whether or not to replay. Also record the information. Therefore, when there is a replay request later, the time until execution of the replay operation can be shortened.

FIG. 8 is a flowchart illustrating an example of a process for determining whether or not the target is a replay target.
The determination as to whether or not it is a replay target in step S7.5 in FIG. 7 is made by the information processing server 100 by the process shown in FIG.
That is, the information processing server 100 determines whether or not the device is a projector in step S8.1, and determines whether or not the device is an electronic blackboard in step S8.2. If the device is a projector or an electronic blackboard, step S8 is performed. .3 Determined to be replayed. If it is neither a projector nor an electronic blackboard, the information processing server 100 determines in step S8.4 that it is not subject to replay.

  This processing corresponds to the above-described replay target determining means determining that the output device is a replay target only when the output device is a projection or display device such as the projector 400 or the electronic blackboard 500.

FIG. 9 is a flowchart illustrating another example of processing for determining whether or not a replay target.
This process is an example in which a display time is added to a condition for determining a replay target in the process shown in FIG. Therefore, when the information processing server 100 determines in step S9.1 that the device is a projector or in step S9.2, the information processing server 100 determines that the device is an electronic blackboard, the display time is a predetermined time in step S9.3. It is determined whether this is the case. As a result, only when the information processing server 100 determines that the display time is equal to or longer than a certain time, the information processing server 100 determines to be a replay target in step S9.4. Otherwise, it is determined not to be replayed in step S9.5.

Therefore, the information processing server 100 determines that the device is a replay target only when the device is the projector 400 or the electronic blackboard 500 and the display time is equal to or longer than a predetermined time, and otherwise it is not a replay target. Judge.
For example, in the history data table shown in FIG. 6A, the history data table when the predetermined time is 10 seconds is as shown in FIG. 6B.
In the history data table shown in FIG. 6B, history IDs 00008 and 00010 whose display time is shorter than 10 seconds are “not subject to replay”.

In this process, the replay target determining means determines that the output device is a replay target only when the output device is a projection or display device such as the projector 400 or the electronic blackboard 500 and the projection or display time is a predetermined time or more. It corresponds to that.
This is because, when it is desired to project an image of a specific page among the images of a plurality of pages, the image of the intermediate page may be projected for a short time before the image of the target page is projected. Therefore, an image that is projected for a moment during page turning is not a target for replay, and an image of a necessary page can be quickly replayed.

[Operation screens displayed on information terminals and their operations]
FIG. 10 is a diagram illustrating an example of an operation screen displayed on the information terminal 200.
A screen as shown in FIG. 10 is displayed on the display surface of the LCD 60 shown in FIG. 4 of each information terminal 200 used in the conference support system. On this screen, the touch panel of the operation unit 70 is arranged so as to overlap, and the operation unit 70 detects a touch operation of each button on the screen.

As the operation screen, it is possible to create / edit conference information, join / exit a conference, select a device to be used for a cooperative operation, and select a file.
In the file selection, it is assumed that a conference material file and a history file stored in the information processing server and a local file held in the information terminal 200 can be selected.
In the screen example shown in FIG. 10, a history file is selected as input selection, and printing is selected as output.

FIG. 11 is a flowchart showing the flow of processing according to the [select from device] operation on the display screen in the information terminal 200. Examples of screens at each step are shown in FIGS.
When the information terminal 200 starts the process of FIG. 11, first, the initial screen (shown in FIG. 12) of the conference support system is displayed in step S11.1.
Then, in step S11.2, the information terminal 200 waits for the [Select from device] tab to be touched on the screen.

If the information terminal 200 determines in step S11.2 that the [Select from device] tab has been touched, the information terminal 200 proceeds to step S11.3 and displays a selection screen (shown in FIG. 13) from the device. In the display screens of FIGS. 13 to 19, “projector”, “MFP”, and “electronic blackboard” are displayed as selectable devices. “Electronic blackboard” is indicated by the abbreviation “IWB”.
If the [Select from file] tab is touched in step S11.2, the screen shifts to a selection from file screen, but the processing in that case is omitted here. The processing in that case will be described later with reference to FIG.

If the information terminal 200 displays the [Select from device] screen in step S11.3, waits for the [MFP] tab of the device type to be touched in step S11.4, and determines that it has been touched. In step 11.5, an MFP screen (shown in FIG. 14) is displayed.
Again, when a tab of another device is touched on the selection screen from the device, the “projector” screen or the “electronic blackboard” screen is displayed, but the processing in that case is omitted here.

Thereafter, the information terminal 200 waits for the [Print] tab of the function type on the MFP screen to be pressed in step S11.6, and determines that it has been touched. In step S11.7, the information terminal 200 selects the input / output selection screen. (Shown in FIG. 15) is displayed.
Again, if the [Scan] tab is touched in step S11.6, the screen shifts to the scan selection screen, but the processing in that case is omitted.

Then, the information terminal 200 determines whether or not an input file selection operation has been performed in step S11.8, and if it is determined that an input file selection operation has been performed, in step 11.9, a file selection screen (see FIG. 16). Display).
If it is determined in step S11.8 that the input file selection operation has not been performed, the information terminal 200 determines in step S11.10 whether or not an input device selection operation has been performed. If the information terminal 200 determines that an input device selection operation has been performed, the information terminal 200 displays an input device selection screen (shown in FIG. 17) in step S11.11.

  If the information terminal 200 determines that the input device selection operation has not been performed in step S11.10, the information terminal 200 determines whether or not the output device selection operation has been performed in step S11.12. If the information terminal 200 determines that the output device selection operation has been performed, the information terminal 200 displays an output device selection screen (shown in FIG. 18) in S11.13, and if the information terminal 200 determines that the output device selection operation has not been performed, Return to S11.8.

The information terminal 200 advances the processing from step S11.9, S11.11, S11.13 to step S11.14, determines whether the input / output setting is completed, and if not completed, the process proceeds to step S11.8. The process returns to step S11.8 to S11.14. When the input / output setting is completed, an operation operation screen (shown in FIG. 19) is displayed in step S11.15.
When an operation operation instruction is given here, normally, when the [print start] tab is touched, the information terminal 200 transmits the set selection information and the print start instruction to the information processing server 100. Thereby, the cooperative operation with the device selected by the control of the information processing server 100 is started.

FIG. 20 is a flowchart showing the flow of processing according to the “select from file” operation on the display screen in the information terminal 200. Examples of screens at each step are shown in FIGS.
When the information terminal 200 starts the process in FIG. 20, first, in step S20.1, the information terminal 200 displays an initial screen (shown in FIG. 21) of the conference support system.

Then, the information terminal 200 waits for the [Select from file] tab to be pressed in the next step S20.2, and if it is determined that the [Select from file] tab has been pressed, the information terminal 200 selects from the file in Step S20.3. Is displayed (shown in FIG. 22).
If the [Select from device] tab is touched in step S20.2, the screen shifts from the device to the selection screen, but the processing in that case is omitted here. The processing in that case has been described above with reference to FIG.

The information terminal 200 displays a selection screen from the file in step S20.3, waits for the input file to be selected in step S20.4, and determines that the input file has been selected. A type selection screen (shown in FIG. 23) is displayed.
Thereafter, the information terminal 200 waits for the function type to be selected in step S20.6, and if it is determined that the function type is selected, displays the operation operation screen (shown in FIG. 24) in step S20.7.

  In this example, since “print” is selected as the function type, when an instruction of “print start” is given as an operation operation, the information terminal 200 sends the selected file name and print start instruction to the information processing server 100. Send to. As a result, the information processing server 100 transmits a document or image data of the selected file to the MFP 600 and starts a cooperative operation for printing by the printer function.

On the function type selection screen (shown in FIG. 23) in step S20.5, [Projector Projection] or [Electronic Blackboard Projection] can be selected as the function type in addition to [Print].
If they are selected, the information terminal 200 displays a screen on which one of [projection condition], [start projection], and [stop projection] can be selected on the operation operation screen in step S20.7.
When an instruction of [Start Projection] is performed, the information terminal 200 transmits the selected file name and an instruction to start projection to the information processing server 100. As a result, the information processing server 100 transmits the image or document data of the selected file to the projector 400 or the electronic blackboard 500, and starts a cooperative operation for projecting the image or document.

[Overview of replay operation]
FIG. 25 is an enlarged view showing an example of a replay operation screen displayed on the information terminal 200.
Information on this replay operation screen is sent from the information processing server 100 to the information terminal 200, and as a list for performing a replay operation, a history in which the item “replay” is “target” in the history data table shown in FIG. Display a list of information in a selectable manner.

Therefore, when the information processing server 100 receives a replay request from any of the information terminals 200, the information processing server 100 stores information on documents and images that can be replayed based on the history information as illustrated in FIG. 6A or FIG. 6B. 200 to be displayed as a list. That is the function of the replayable information providing means described above by the information processing server 100.
Further, the replayable information providing means of this embodiment has means for extracting a history recorded as a replay target in the history information and creating a list of replayable documents and images. Therefore, a list for performing the replay operation can be created in a short time.

  On this replay operation screen, a list for performing a replay operation is displayed in order from the oldest to the newest. The output order is in a state in which “from the top” is selected (the button is grayed out in the figure). The case where [From the last] is selected will be described later. The replay target device, the output device, and the display time can be selected or set, and the output device can be changed by selecting the target device and selecting the changed device. FIG. 25 shows a state where none is selected (or set).

  When the [Execute] button is touched, the information terminal 200 sends the selected information and an execution command instruction to the information processing server 100. As a result, the information processing server 100 performs a cooperative operation with the projector 400 or the electronic blackboard 500, and starts a replay operation in order from the top of the list. When the [Cancel] button is touched, the information terminal 200 sends a replay stop command instruction to the information processing server 100 to stop the replay operation.

FIG. 26 is a sequence diagram illustrating a flow of data between devices when performing a replay operation.
First, the information terminal 200 acquires device (conference) information, which is information necessary for creating a replay operation screen, from the information processing server 100. This information includes an output device, an operator (user), a history, and the like.
The information terminal 200 creates a replay operation screen based on the acquired information, determines the command instruction content by the user operation, and sends a command instruction for executing the replay operation to the information processing server 100.

Upon receiving the command instruction, the information processing server 100 generates a job from the history stored and stored based on the instruction content, and outputs the first image data to be projected on the output device (in this example, the projector 400) together with the job request. Send.
The output device (projector 400) performs a projection process by outputting the image data, and returns a job response to the information processing server 100. This process is continued until the job is completed by projecting all images to be replayed.

  When the output device is the electronic blackboard 500, the information processing server 100 transmits the document data output to be projected to the electronic blackboard 500 together with the job request. Project. Alternatively, only the contents of the specified page are projected.

FIG. 27 is a flowchart illustrating a replay operation process performed by the information processing server 100. This example is a case of replay in which an image to be replayed is projected onto a projector 400 that is an output device.
When the information processing server 100 receives a command instruction for starting a replay operation from the information terminal 200, the information processing server 100 starts the process of FIG. Then, in step S27.1, the information processing server 100 first extracts a list for performing the replay operation from the history based on the instruction.

  In step S27.2, the information processing server 100 sets the count value i of the number of replayed screens to 0, and in step S27.3, if i is less than the number of screens to be replayed, the process proceeds to step S27.4. To proceed. When i is not less than the number of screens to be replayed, that is, when projection of the number of screens to be replayed is completed, this processing is terminated.

In step S27.4, the information processing server 100 sends the i-th (initially 0th) image from the list for performing the replay operation to the output device (in this case, the projector 400) for projection. The information processing server 100 sets i to i + 1 in step S27.5, waits for a specified time (display time in the history data table) until the next screen display time in step S27.6, and then proceeds to step S27.3. Return.
Thereafter, the information processing server 100 repeats the processes of steps S27.3 to S27.6 until the number of screens to be replayed = i.

This process is a function of a replay control unit that, when receiving a replay execution instruction from the information terminal 200, causes the output device previously output based on the history information to replay the documents and images displayed in the list.
As described above, in the conference using the above-described conference support system according to the embodiment of the present invention, the operation history for the data (document / image) handled by the information processing server 100 during the conference is recorded, and based on the operation history. Replay operation. Therefore, the operability for viewing the previously displayed data again can be improved.

[When replaying from the end of the list]
The list information for performing the replay operation that the information terminal 200 first acquires from the information processing server 100 is in order from the oldest to the newest. Therefore, as shown in FIG. 25, the information terminal 200 displays the replay operation screen in order from the oldest date and time in the order from the top. At this time, as described above, the output order is in a state in which “from the top” is selected (the button is displayed in gray in the figure).

Therefore, when the operator of the information terminal 200 wants to reverse the replay order and start from the newest date and time, when the “From the last” button is selected on the replay operation screen shown in FIG. 25, as shown in FIG. Is selected (button is grayed out in the figure).
At this time, the information terminal 200 notifies the information processing server 100 that “From the end” has been selected. When the information processing server 100 receives the notification, the information processing server 100 updates the list for performing the replay operation by rearranging the list from the newest to the oldest, and transmits the updated list information to the information terminal 200.

The information terminal 200 receives the updated list information and, as shown in FIG. 28, displays a list for performing the replay operation in order from the newest date and time from the top.
In this state, when the [Execute] button is touched, the information terminal 200 sends the selected information and an execution command instruction to the information processing server 100. Accordingly, the information processing server 100 performs a cooperative operation with the projector 400 or the electronic blackboard 500, and starts a replay operation from the top of the updated list, that is, in order from the newest date and time.

This corresponds to the fact that the replay control means has means for switching whether to replay the documents and images displayed in the list in order of oldest history or in order of newest history according to the selection at the information terminal 200. .
In this way, replayable documents and images can be arbitrarily selected and replayed as necessary from the oldest history or the oldest history.

[When display time is set]
The display time can be set on the replay operation screen shown in FIG. When the display time is set, the set display time is notified from the information terminal 200 to the information processing server 100.
Processing of the replay operation by the information processing server 100 in that case will be described with reference to the flowchart of FIG.

The process of steps S29.1 to S29.5 in FIG. 29 is the same as the process of steps S27.1 to S27.5 in FIG.
The information processing server 100 determines whether or not the display time is set in step S29.6 in FIG. 29. If not, the information processing server 100 sets the display time in the history data table as the standby time in step S29.7. In S29.8, the set time is set as a standby time.
Thereafter, the information processing server 100 waits for the waiting time in S29.9, and then returns to step S29.3. Thereby, each screen to be replayed can be projected for a set display time.

The processing of steps S29.6 to S29.9 performed by the information processing server 100 controls the replay processing time for each document and image to be replayed by the replay control means described above to the time specified by the information terminal 200. It corresponds to having a means to do.
As a result, it is possible to replay each page of a document and an image to be viewed again in an appropriate fixed time or in a short time.

[When a replay target device is selected]
On the replay operation screen of the information terminal 200, a replay target device can be selected.
FIG. 30 shows an example of a replay operation screen of the information terminal 200 when the replay target device is set to “electronic blackboard”.
When the “electronic blackboard” is selected and set as the replay target device on the replay operation screen shown in FIG. 25, the information terminal 200 notifies the information processing server 100 of it.

Upon receiving the notification, the information processing server 100 updates only the history output to the electronic blackboard among the replay targets in the history data table as a list for performing the replay operation, and sends the updated list information to the information terminal 200.
The information terminal 200 receives the updated list information and displays only the history output on the electronic blackboard as a list for performing the replay operation on the replay operation screen as shown in FIG.

  When the [Execute] button is touched in this state, the information terminal 200 sends an execution command instruction to the information processing server 100. As a result, the information processing server 100 performs a cooperative operation with the electronic blackboard 500, sends the document file to the electronic blackboard 500 from the top of the updated list, and starts a replay operation. When “from the end” is selected as the output order, the document file is sent to the electronic blackboard 500 from the end of the updated list, and the replay operation is started.

When “projector” is selected and set as a replay target device on the information terminal 200, the information processing server 100 that has received the notification performs a replay operation on only the history output to the projector among the replay targets in the history data table. Update as a list. Then, the updated list information is sent to the information terminal 200.
The information terminal 200 receives the updated list information and displays only the history output to the projector as a list for performing the replay operation on the replay operation screen.

  In this state, when the [Execute] button is touched, the information terminal 200 sends an execution command instruction to the information processing server 100. As a result, the information processing server 100 cooperates with the projector 400 to send the document file to the projector 400 from the beginning or end of the updated list (depending on the output order setting), and start the replay operation.

This processing by the information processing server 100 causes the replay control means described above to cause the output device to replay only those documents and images that can be replayed whose output device is the output device designated by the information terminal 200. This corresponds to having means.
Thereby, only the document or image output (projected or displayed) by a specific output device can be easily replayed.

[When output device change is set on the replay operation screen]
The output device to be replayed can be changed on the replay operation screen shown in FIG.
For example, in the conference support system shown in FIG. 1, when two projectors 400 are connected to the conference network 700, they are referred to as “projector 1” and “projector 2”.

Then, as shown in the replay operation screen shown in FIG. 31, when the history projected by “projector 1” is displayed as a list for performing the replay operation, “projector 1” is set as the target device, and the change device is set as the change device. “Projector 2” can be set. As a result, the output of “projector 1” is set to be output to “projector 2”.
When the [execute] button is touched on the replay operation screen shown in FIG. 31, the information terminal 200 notifies the information processing server 100 of the output device change setting information together with an execution command instruction. Receiving it, the information processing server 100 performs a cooperative operation with “projector 2” and starts a replay operation so that the output of “projector 1” is output to “projector 2”.

A processing example of the replay operation by the information processing server 100 when the output device is changed and set in this manner will be described with reference to the flowchart of FIG.
The processes in steps S32.1 to S32.3, S32.8, and S32.9 in FIG. 32 are the same as the processes in steps S27.1 to S27.3, S27.5, and S27.6 in FIG.

In the process shown in FIG. 32, the information processing server 100 acquires the i-th output device from the list for performing the replay operation in step S32.4.
In the next step S32.5, the information processing server 100 determines whether or not the acquired output device is a target device for output change. If it is determined that the output device is a target device for output change, the information processing server 100 outputs in step S32.6. The device to be processed is set as the output device set as the changed device, and the process proceeds to step S32.7.
If the information processing server 100 determines in step S32.5 that the device is not the target of output change, the information processing server 100 proceeds to step S32.7 without changing the output device.
In step S32.7, the information processing server 100 projects the i-th image from the list on which the replay operation is performed on the output device.

  In the example of FIG. 31, when the i-th output device from the list performing the replay operation is “projector 1”, the output device acquired by the information processing server 100 is the target device for output change. It is assumed that “projector 2” is set in the change device. Then, the information processing server 100 causes the “projector 2” to project the i-th image from the list of screens to be replayed.

The processing of steps S32.5 to S32.7 in FIG. 32 by the information processing server 100 corresponds to the above-described replay control means having the following means. When the output device of the document or image to be replayed is an output device designated as a change target by the information terminal 200, the means sends the document or image to the output device designated as the change device by the information terminal 200. This is means for replaying an image.
As a result, the document or image output to a specific output device can be replayed and viewed on another easily output device.

[When output device designation is set on the replay operation screen]
On the replay operation screen shown in FIG. 25, it is possible to specify an output device to be replayed and set it to output only to a specific output device.
For example, the replay operation screen shown in FIG. 33 shows an example when the output device designation is set to “projector”.

  When the [Execute] button is touched on the replay operation screen shown in FIG. 33, the information terminal 200 notifies the information processing server 100 of the information in which the output device designation is set, together with an execution command instruction. Receiving it, the information processing server 100 performs a cooperative operation with the designated output device, and starts the replay operation so that the image or document to be replayed is output to the designated output device. In the example shown in FIG. 33, since the output device designation is set to “projector”, all images to be replayed are projected onto the projector 400.

A processing example of the replay operation by the information processing server 100 when the output device designation is set in this way will be described with reference to the flowchart of FIG.
The processes in steps S34.1 to S34.3, S34.8, and S34.9 in FIG. 34 are the same as the processes in steps S27.1 to S27.3, S27.5, and S27.6 in FIG.

In the process shown in FIG. 34, the information processing server 100 determines whether or not an output device is specified in step S34.4. If it is determined that there is an output device specified, the information output server specifies an output device in step S34.5. As the output device set in step S34.7, the process proceeds to step S34.7.
If the information processing server 100 determines in step S34.4 that there is no output device designation, in step S34.6, the information processing server 100 acquires the i-th output device from the list that performs the replay operation, and proceeds to step S34.7.
In step S34.7, the information processing server 100 projects the i-th image from the list on which the replay operation is performed on the output device.

  In the example of FIG. 33, since the output device is designated and the output device set by the output device designation is “projector”, the information processing server 100 sets i to be output from the list for performing replay operation with all the devices to be output as projectors. The second image is projected on the projector 400.

The processing of steps S34.4 to S34.7 in FIG.
This corresponds to the replay control means described above having the following means. The means is a means for replaying a replayable document and image only on the output device designated by the information terminal 200, regardless of the output device recorded in the history information.
Thereby, since the document or image output to the several different output device can be projected or displayed with the same output device, it can make a replay image easy to see.

[Other Embodiments]
Hereinafter, another embodiment of the information processing apparatus and the conference support system using the same according to the present invention will be described. Also in this embodiment, since the system configuration, the hardware configuration, and the basic functions are the same as those in the above-described embodiment, only differences will be described. The code of each device is also the code used in the above embodiment.

FIG. 35 is a flowchart showing the flow of history data table recording processing by the information processing server 100 in this embodiment.
Steps S35.1 and S35.2 in FIG. 35 are the same as steps S7.1 and S7.2 in FIG. However, the processing is terminated without performing the processing corresponding to steps S7.3 to S7.7 in FIG.

That is, the information processing server 100 starts the process shown in FIG. 35 every time there is an access request from the information terminal 200. Then, in step S35.1, when the last history ID in the history data table is N, the information terminal 200 sets the new history ID to N + 1, and in step S35.2, sets the history ID as a new N and adds the history ID to the history. Make the following record:
・ Conference ID ・ Date ・ Operator ・ Document (image) file path ・ Device name (ID) ・ Processing content

Then, the process ends. The recorded items are as described above in the description of FIG.
Therefore, in this embodiment, when the information processing server 100 updates the history data table, the display (projection) time is not recorded, and it is determined whether the document or image file is a target of replay or not. The recording is not performed.
An example of the history data table created by the information processing server 100 in this way is shown in FIG. In this history data table, the display time and whether or not to be replayed are not recorded.

Thereafter, when the information processing server 100 receives a replay request from the information terminal 200, the processing shown in FIG. 37 is performed to create a list for performing the replay operation.
Therefore, when the information processing server 100 receives a request from the information terminal 200, it starts the process of “create a list for performing a replay operation from the history” shown in FIG.
The information processing server 100 sets both “n” and “m” to 1 in step S37.1. n is a numerical value indicating the history number in the history data table, and m is a numerical value indicating the number of the list in which the replay operation is performed.

In step S37.2, the information processing server 100 determines whether n has exceeded the number of histories in the history data table. If it has exceeded, the process ends because the last history has been read. If not, the process proceeds to step S37.3.
In step S37.3, the information processing server 100 reads the nth (initially first) history in the history data table. Then, the information processing server 100 determines whether or not the read history is “projection” in the next step S37.4, and in the case of No, whether or not “save image on electronic blackboard” in step S37.5. In this case, if the answer is No, the process proceeds to step S37.10 without doing anything. Then, the information processing server 100 adds 1 to n to n + 1 in step S37.10, and returns to step S37.2.

If the information processing server 100 determines that the read history is “projection” or “store image on electronic blackboard”, in step S37.6, the information processing server 100 selects the mth ( The first is the first).
Next, in step S37.7, the information processing server 100 searches for processing for the same device from the (n + 1) th and subsequent histories. Then, in step S37.8, the information processing server 100 calculates a time difference between the nth history and the history of the first hit in the search in step S37.7, and calculates it as the mth in the list for performing the replay operation. Record as display time.

Thereafter, the information processing server 100 adds 1 to m to m + 1 in step S37.9, adds 1 to n to n + 1 in step S37.10, and returns to step S37.2.
Then, the information processing server 100 repeats the above-described process until n exceeds the number of histories in the history data table in step S37.2, and creates a list for replay operation. An example of the list of replay operations created in this way is shown in FIG.

  The processing of FIG. 37 by the information processing server 100 corresponds to the function of replayable information providing means having the following means. When a replay request is received from any of the information terminals 200, the means extracts a history whose processing content is projection or display or projection or storage of an image on a display device from the history information, and a replayable document And means for creating a list of images. In this example, the means further extracts only histories whose processing time is a certain time or more from the histories, and creates a list of documents and images that can be replayed. Accordingly, a history document or image whose processing time is less than a certain time is not set as a replay target.

Display information for replay based on such a list of replay operations can be sent to the information terminal 200 to which the information processing server 100 has requested replay, and a replay operation screen as shown in FIG. 39 can be displayed.
On this replay operation screen, a list showing the replayable file name, its operator name, operation content, and operation date and time is displayed as replay display information.

The file name corresponds to “document / image file path” in the list of replay operations shown in FIG. The operator name is “operator” in the replay operation list, but even if it is recorded with the participant ID, it is based on the correspondence table of the names and participant IDs of all participants registered in advance. It is possible to display the name of the operator. The operation content is created from “use device” and “processing content” in the list of replay operations.
In this way, replayable files can be displayed in an easy-to-understand manner.

Note that the information processing server 100 may store a table in which, for example, as illustrated in FIG. 40, a participant is associated with unique information of an information terminal used by the participant. The participant ID is a unique ID (identification number) assigned to each participant in the conference. The Mac address of the information terminal is information unique to the information terminal used by each participant. As information unique to each information terminal, an IP address, a device ID, a near field communication ID, or the like may be used.
Various restrictions can be applied to the replay operation using the correspondence between the information unique to each information terminal and the participant ID, which will be described later. Here, the operator name is displayed according to the correspondence between the participant name and the participant ID.

When the execution button on the replay operation screen is touched by the user, a replay execution command is sent from the information terminal 200 to the information processing server 100. Thereby, the information processing server 100 executes the replay operation in the same manner as in the above-described embodiment, based on the created “list for replay operation”.
In the replay operation screen of FIG. 39, since “from the top” is selected, the replay is executed from the top (top) of the list, that is, in the order of the date and time of the previous operation. When “from the end” is selected on the replay operation screen, the replay is executed from the end (bottom) of the list, that is, in the order from the latest operation date and time.

[Operator selects file to replay]
In this embodiment, the history data table, which is the history information created and recorded by the information processing server 100, includes identification information for identifying the operator of the information terminal accessed at the time of creation (see FIG. 36). The identification information for specifying the operator can be known from the MAC address of the accessed information terminal by the table shown in FIG.
An operator is also included in the “list for performing a replay operation (see FIG. 38)”, which is information related to replayable documents and images that the information processing server 100 creates based on the history data table.

Therefore, the information terminal 200 to which the information is transmitted displays a list in which replayable file operators are clearly shown on the replay operation screen as shown in FIG.
Therefore, in order to allow a conference participant who uses the information terminal 200 (hereinafter also referred to as “user”) to select a file to be replayed by the operator displayed in the list, the “operation” is displayed on the replay operation screen. "Select person" button is displayed (see FIG. 39).

When the user touches the “operator selection” button, as shown in FIG. 41, the color of the “operator selection” button changes and a screen for selecting an operator is displayed in a hop-up manner. There are displayed selectable operator names and select buttons for individually selecting them.
When the user touches the selection button, it is highlighted (inverted from white to black in the figure), and the operator on the right side is selected.
The state shown in FIG. 41 shows a state where “Tanaka” and “Sato” are selected as operators. In this manner, a plurality of operators can be selected.

As described above, after the operator of the file to be replayed is selected, when the user touches the “execute” button on the replay operation screen, the information terminal 200 displays the information of the selected operator and the replay execution instruction on the information processing server. To 100.
When the information processing server 100 receives the information, the replay control unit selects only the same replayable document and image that the operator recorded in the history information is the same as the operator selected by the information terminal 200. Let the replay process.
In this way, it is possible to easily select a document or image that needs to be replayed and execute the replay.

At this time, when a plurality of operators are selected by the information terminal 200, among the replayable documents and images, the operator recorded in the history information is the same as one of the selected plurality of operators. Are continuously replayed.
In this way, when the operators are divided into multiple groups at a conference such as a presentation of Company A and Company B and you want to replay only the information of a specific group, or when multiple people present meeting materials in a group It is possible to replay it easily.

Alternatively, a file that does not require replay may be designated (selected) by the operator on the operator selection screen displayed as a hop-up display on the replay operation screen shown in FIG.
In this case, when the information processing server 100 receives the information (replay execution instruction) of the operator specified (selected) from the information terminal 200, the operator recorded in the history information is specified from the replayable documents and images. The replay processing is performed by excluding the same operator as the performed operator.
This can be realized by providing the replay control means with such a function.

In this case as well, a plurality of operators who exclude replay can be designated. When a plurality of operators are designated, the replay control means of the information processing server 100 is the same as any one of the plurality of operators designated by the operators recorded in the history information among the replayable documents and images. Exclude everything and let the replay process.
In this way, information on operators other than a specific operator or operators other than a plurality of operators such as a specific group can be easily replayed.

In the examples described so far, anyone of the conference participants can replay documents and images such as materials used in the conference. However, only those who have specific authority among the conference participants can perform the replay operation.
In that case, the information processing server 100 may execute the replay process only when receiving a replay execution instruction from the information terminal 200 used by a person having specific authority among the conference participants. That is, the replay control means of the information processing server 100 has means for executing replay processing only when a replay execution instruction is received from the information terminal 200 used by a person having specific authority among the conference participants. To do.

For this reason, when the information terminal 200 transmits a replay execution instruction to the information processing server 100, it also notifies a Mac address that is unique identification information of the information terminal. Further, the Mac address or participant ID of the information terminal used by the conference participant having special authority such as the conference organizer is registered in advance. The MAC address of the information terminal used by the participant based on the participant ID is uniquely determined by referring to the table shown in FIG.
When the information processing server 100 receives a replay execution instruction from the information terminal 200, the notified Mac address matches the registered MAC address of the information terminal used by the conference participant having the special authority. Only when the replay process is executed.

If anyone in the conference can perform replay operation, unnecessary replay may be started, but only those with specific authority, such as the conference organizer, can execute the replay execution instruction. You can prevent it.
It is also possible to prevent redisplay of a document or screen that is displayed erroneously and is not desired to be displayed again.

However, even an operator who does not have administrator authority may wish to be able to replay only the information that he / she has output.
In that case, the replay control means of the information processing server 100 matches the operator who uses the information terminal instructed to execute the replay, among the replayable documents and images, the operator recorded as history information. Means for replay processing only.

The operator who uses the information terminal instructed to execute replay is a participant with a participant ID (see FIG. 40) corresponding to the Mac address notified from the information terminal 200 instructed to execute replay.
In this way, it is possible to prevent an operator who does not have special authority from replaying even the information he / she has output. In addition, it is possible to prevent other people from replaying the information that they output.

As mentioned above, although embodiment of this invention has been described, the concrete structure of each part of each embodiment, the content of a process, etc. are not restricted to what was described there.
Further, the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention is not limited in any way except for having the technical features described in the claims.
Furthermore, the configuration examples, operation examples, modification examples, and the like of the embodiments described above may be appropriately changed, added, or partly deleted, and may be implemented in any combination as long as they do not contradict each other. .
