Then, in the content management server 6, the personal electronic campus dc3 provides the data of the content “C” to the shared electronic campus cc (S8). Thereby, the content management server 6 transmits the data of the content “RC” to all the personal terminals 2 (personal terminals 2a and 2c in FIG. 5) participating in the remote conference (S9-1, 2). In the personal terminal 2a, the content "RC" is displayed in the operation display area 112a by the web browser (S10-1), and in the personal terminal 2c, the content "RC" is displayed in the operation display area 112c by the web browser (S10- 2).

  As described above, when the content is displayed by the web browser of the personal terminal 2c, the user C of the personal terminal 2c drags and drops on the personal terminal 2c from the operation display area 102c to the desired position of the operation display area 112c. By performing the operation of copying the content "C" of the screen element, the content management server 6 can copy the data of the content "C" of the screen element from the private electronic campus dc3 to the shared electronic campus cc. ..

  In the present embodiment, data is not copied in the personal terminal 2c in order to copy the content of the operation display area 102c to the operation display area 112c. The data is copied by the content management server 6, and the personal terminal 2c displays the copied content by the web browser.

  Further, in the present embodiment, the content is dragged and dropped from the individual operation display area 102c displayed on the personal terminal 2c to the shared operation display area 112c, but the present invention is not limited to this. For example, content may be dragged and dropped from the individual operation display area displayed on the personal terminal 2a or the personal terminal 2b to the shared operation display area.

(Details of processing or operation)
Subsequently, the details of the process or operation in the first embodiment will be described with reference to FIGS. 6 to 10. FIG. 6 is a sequence diagram showing a process of inputting and displaying contents. Here, the process (S5) after the above-mentioned precondition will be described in detail.

  First, when the user C inputs the content “IC” of the screen element with the keyboard 211 and the mouse 212 on the personal terminal 2c, the reception unit 22c receives the input (S21). Then, the transmitting / receiving unit 21c transmits the data of the content “IC” of the screen element and the display position information p1 indicating the display position of the content on the personal electronic campus dc3 to the content management server 6 (S22). As a result, the transmission / reception unit 61 of the content management server 6 receives the data of the content “IC” and the display position information p1.

  Next, in the content management server 6, the storage / read processing unit 69 causes the personal content management table in the personal content management DB 6001 in which the URL of the personal electronic campus dc3 is managed, to display the data of the content “IC” and the display position information p1. Are stored in association with each other (S23). Then, the creating unit 63 creates the unique content ID 11 (S24).

  Next, the storage / readout processing unit 69 stores the content data and the display position information p1 stored in step S23 in association with the content ID 11 created in step S24 (S25).

  Next, the transmission / reception unit 61 transmits an update notification, which is a notification to update the personal electronic campus, to the personal terminal 2c (S26). When the user C has a plurality of personal terminals and accesses the same personal electronic campus (URL) from each, the content management server 6 updates the plurality of personal terminals of the user C. Send a notification. As a result, the transmission / reception unit 21c receives the update notification by the web browser that displays the operation display area 102c of the personal terminal 2c.

  Next, the transmission / reception unit 21c transmits a request for updated content data and display position information to the content management server 6 by the web browser displaying the operation display area 102c of the personal terminal 2c (S27). .. As a result, the transmission / reception unit 61 of the content management server 6 receives the request.

  Next, in the content management server 6, the storage / read processing unit 69 uses the personal content management table for the personal electronic campus dc3 in the personal content management DB 6001 to retrieve the content ID 11 and the data of the content “IC” relating to the updated content. The display position information p1 is read (S28). Then, the transmission / reception unit 61 transmits the content ID 11, the data of the content “IC”, and the display position information p1 to the personal terminal 2c (S29). As a result, the transmitter / receiver 21c receives the content ID 11, the data of the content “IC”, and the display position information p1 by the web browser of the personal terminal 2c.

  Next, in the personal terminal 2c, the storage / read processing unit 29c stores the personal content management DB 2001c in association with the content ID 11, the data of the content “IC”, and the display position information p1 received in step S29. Yes (S30). Thus, the display controller 24c updates the operation display area 102c to display the content "IC", which is a screen element, by the web browser of the personal terminal 2c (S31).

  With the above, the process of inputting and displaying the content ends.

  Subsequently, a copy process when the content to be copied is a screen element will be described with reference to FIGS. 7 to 10. 7 and 10 are sequence diagrams showing the copy process when the content to be copied is a screen element. FIG. 10 shows a continuation of the processing of FIG. FIG. 9 is a flowchart showing the request content determination process.

  First, when the user C specifies the content “C” of the content “IC” with the mouse 212 of the personal terminal 2c, the reception unit 22c receives the specification of the content “C” (S41). Then, when the user C drags with the mouse 212, the reception unit 22c receives the drag of the content "C" (S42). Then, the storage / readout processing unit 29c reads out the content ID 11 corresponding to the drag and the URL of the personal campus dc3 from the personal content management DB 2001c, and temporarily stores it in the clipboard of the storage unit 2000c (S43).

  Next, when the user C drops the content “C” at a desired display position in the operation display area 112c with the mouse 212, the reception unit 22c receives the drop (S44). The image processing unit 23c acquires the display position information p2 indicating the position of the drop on the shared electronic campus cc by the web browser of the personal terminal 2c (the web application thereof) (S45). As described above, the personal terminal 2c acquires the display position information p2 on the operation display area 112c separately from the display position information p1 on the operation display area 102c shown in FIG. The reason for acquiring the display position information p2 will be described with reference to FIG.

  In FIG. 8, (a) is a conceptual diagram showing the operation display area and the display position of the content on the infinite private campus, and (b) is a conceptual diagram showing the operation display area and the display position of the content on the infinite shared electronic campus. Is.

  As shown in FIG. 8A, the personal electronic campus dc3 is made up of an infinite area, and an arbitrary area of this infinite area is displayed in the operation display area 102c. On the other hand, as shown in FIG. 8B, the shared electronic canvas cc is also made up of an infinite area, and an arbitrary area of this infinite area is displayed in the operation display area 112c. In FIG. 8, in the operation display area 102c and the operation display area 112c, infinite different areas of the electronic campus are displayed.

  Then, as shown in FIG. 8A, the content display position (p1) is on the right side of the individual operation display area 102c. In this state, if the content of the personal electronic campus dc3 is copied to the same position of the shared electronic campus cc, there is a problem that the content is not displayed in the shared operation display area 112c as shown in FIG. 8B. Occurs. Therefore, the personal terminal 2c uses the position (p1) of the content based on the operation display area 102c, not the personal electronic campus dc3, based on the position (p2) of the content based on the operation display area 112c, not the shared electronic campus cc. By acquiring), the content is displayed at the same position in the appearance of the user.

  Next, returning to FIG. 7, the storage / readout processing unit 29c reads out the content ID 11 and the URL of the personal electronic campus dc3 stored in the storage unit 2000c (S46). Then, the transmitting / receiving unit 21c transmits a content copy request (information thereof) to the content management server 6 by the web browser that displays the operation display area 112c (S47). This copy request includes the display position information p2 acquired in step S45, the content ID 11 and the URL of the personal electronic campus dc3 read in step S46. As a result, the transmission / reception unit 61 of the content management server 6 receives the content copy request.

  Next, the content management server 6 determines the content of the content copy request (S48). Here, the request content determination process will be described with reference to FIG.

  The determination unit 65 determines whether the content ID is received in step S47 (S48-1). When the determining unit 65 determines in step 48-1 that the content ID has been received (YES), it determines that the request is a copy request for the content of the screen element (S48-2). On the other hand, in step 48-1, if the determination unit 65 does not determine that the content ID has been received (or determines that the content ID has not been received) (NO), the content of the entire screen that is the screen capture image is displayed. It is determined that the request is a copy request (S48-3). Since the content ID 11 has been received in step S47, the determination unit 65 determines here that the request is a copy of the content of the screen element.

  Next, returning to FIG. 7, the storage / read processing unit 69 determines the content identified by the content ID from the personal content management table for the personal electronic campus dc3 in the personal content management DB 6001 based on the URL of the personal electronic campus dc3. The data of "C" is read (S49). The creating unit 63 newly creates the content ID 12 (S50). Then, the storage / read processing unit 69 causes the shared content management DB 6002 to display the display position information p2 received in step S47, the data of the content “C” which is the screen element read in step S49, and the step The content ID 12 created in S50 is associated and stored (S51). As a result, in the content management server 6, the data of the content “C” is copied from the personal content management DB 6001 to the shared content management DB 6002. This data copy process corresponds to steps S7 and S8 in FIG. 5 showing the concept of the process.

  Steps S66 to S71 shown in FIG. 10 are the same processes as steps S26 to S31 in FIG. 6, and the personal content management DB 6001 and the personal content management DB 2001c are changed to the shared content management DB 6002 and the shared content management DB 2002c. ing. More specifically, the transmission / reception unit 61 transmits an update notification, which is a notification to update the shared electronic campus, to the personal terminal 2c (S66). When accessing the same shared electronic campus (URL) from a plurality of personal terminals, the content management server 6 sends an update notification to each personal terminal. As a result, the transmission / reception unit 21c receives the update notification by the web browser that displays the operation display area 112c of the personal terminal 2c.

  Next, the transmission / reception unit 21c transmits (request) the updated content data and display position information to the content management server 6 by the web browser displaying the operation display area 112c of the personal terminal 2c. Yes (S67). As a result, the transmission / reception unit 61 of the content management server 6 receives the updated request for content data and display position information.

  Next, in the content management server 6, the storage / read processing unit 69 reads the content ID 12, the content “RC” data, and the display position information p2 related to the updated content from the shared content management DB 6002 (S68). Then, the transmission / reception unit 61 transmits the content ID 12, the data of the content “RC”, and the display position information p2 to the personal terminal 2c (S69). As a result, the transmission / reception unit 21c receives the content ID 12, the data of the content “RC”, and the display position information p2 by the web browser of the personal terminal 2c.

  Next, in the personal terminal 2c, the storage / readout processing unit 29c stores the content ID 12, the content data, and the display position information p2 received in step S69 in association with each other in the shared content management DB 2002c (S70). .. As a result, the display controller 24c updates the operation display area 112c to display the content "RC", which is a screen element, by the web browser of the personal terminal 2c (S71).

<Main effects of the embodiment>
As described above, according to the present embodiment, in the same virtual room, the content “C” of the screen element is displayed from the operation display area 102c displayed by the web browser to the operation display area 112c displayed by the web browser. Since it can be copied, it is possible to meet the needs of coordinating contents among a plurality of operation display areas displayed on a web browser.

  In addition, the user C of the personal terminal 2c performs an operation of copying the content "C" of the screen element from the operation display area 102c to a desired position of the operation display area 112c by dragging and dropping on the personal terminal 2c. On the content management server 6 side, data of the content “C” of the screen element can be data-copied from the personal content management DB 6001 to the shared content management DB 6002. In this way, if the user C performs a local operation (drag and drop) on the personal terminal 2c, the personal terminal 2c sends the content ID and display position information of the content to be copied to the content management server 6, It is not necessary to transmit content data having a relatively large data communication amount from the terminal 2c to the content management server 6. As a result, the communication time can be shortened, and finally, it is possible to further shorten the time until the copied content is displayed on the operation display area 112c by the web browser of the personal terminal 2c.

  Specifically, the time until the copied content is displayed on the operation display area 112c is almost the download time of the data of the content to be copied. For example, assuming that the communication speeds of download and upload are the same, when uploading the content ID and the display position information of the content from the personal terminal 2c to the content management server 6 as in the present embodiment, the content data is personalized by the personal terminal 2c. Compared with the case of copying and uploading content data from the personal terminal 2c to the content management server 6, the content is displayed on the operation display area 112c in about half the time. In addition, in the current network environment, the upload communication speed may be slower than the download communication speed, so in reality, it will be displayed in less time than half. In particular, when the target to be dragged and dropped is not the screen element but the entire screen, the content data amount is large, so in the present embodiment, until the copied content is displayed on the operation display area 112c. The time can be further shortened.

[Second Embodiment]
A second embodiment of the present invention will be described with reference to FIGS. 11 to 13. The general outline, hardware configuration, and functional configuration of the information sharing system are the same as those in the first embodiment, and therefore the processing or operation will be described.

(Outline of processing or operation)
First, the outline of the process or operation in the second embodiment will be described with reference to FIG. FIG. 11 is a conceptual diagram showing a process of copying content from a shared electronic screen to a personal electronic campus according to the second embodiment.

  The operation display area 102c represents an arbitrary area in the infinite personal electronic campus dc3.

  Here, the user A transmits the data of the content of the entire screen in which the text data “RI” is input to the shared electronic screen ss from the personal terminal 2a and shares the screen with the personal terminals 2b, 2c and the shared terminal 4. A situation in which the user C copies the contents of the entire screen shared by the user C to the personal electronic campus dc3 and handles the contents of the entire screen as personal data will be described.

  In the present embodiment, the content of the entire screen is an example of the specific content. A storage position (storage area) on the storage unit 6000 that is an access destination (URL) to the shared electronic screen ss is an example of the first position in the storage unit 6000. The storage location (storage area) on the storage unit 6000 that is the access destination (URL) to the personal electronic campus dc3 is an example of the second location in the storage unit 6000.

  First, in the personal terminal 2a, the content "RI" is displayed on the operation display area 112a, and the content data of the entire screen is transmitted to the shared electronic screen ss of the content management server 6 (S101). As a result, the content management server 6 stores the content data of the entire screen in the storage area for the shared electronic screen ss in the storage unit 6000. The data transmitted in step S101 may be moving image data or still image data.

  Next, the user C displays the operation display area 122c on the personal terminal 2c, and the content management server 6 transmits the content data of the entire screen to the personal terminal 2c (S102). In the personal terminal 2c, the content of the entire screen is displayed in the operation display area 122c by the web browser.

  Further, in the personal terminal 2c, an operation display area 102c for displaying the contents of the personal electronic campus dc3 is displayed.

  In this precondition, the user C copies the content of the entire screen displayed on the operation display area 122c to his / her own personal electronic campus dc3. Then, the screen capture image by the personal terminal 2a) is dragged and dropped and copied to a desired position on the operation display area 102c (S103). In the present embodiment, the operation display area 122c is an example of the first operation display area, and the operation display area 102c is an example of the second operation display area.

  Next, the personal terminal 2c requests the content management server 6 to copy the content of the entire screen by the web browser that displays the operation display area 102c (S104). This copy request includes the URL of the shared electronic screen ss that is the copy source. That is, the copy source can be specified by drag and drop. Note that in the present embodiment, unlike the first embodiment, the content is not the screen element but the entire screen, and there is only one content to be copied on the entire screen, so there is no need to specify the content. Therefore, the content ID of the content on the entire screen is not transmitted.

  Next, in the content management server 6, the personal electronic campus dc3 requests content data from the URL of the shared electronic screen ss (S105). Then, in the content management server 6, the shared electronic screen ss provides the content data of the entire screen to the personal electronic campus dc3 (S106). Thereby, the content management server 6 transmits the content data of the entire screen to the personal terminal 2c participating in the remote conference (S107). On the personal terminal 2c, the content of the entire screen is displayed in the operation display area 102c by the web browser (S108).

  As described above, the user C of the personal terminal 2c performs the operation of copying the content of the entire screen from the operation display area 122c to the operation display area 102c by dragging and dropping on the personal terminal 2c of his / her own. , The data of the content of the entire screen can be data copied from the shared electronic screen ss to the personal electronic campus dc3.

  Note that, also in this embodiment, in order to copy the content of the operation display area 122c to the operation display area 102c, the data is not copied only within the personal terminal 2c. The data is copied by the content management server 6, and the copied content is displayed by the web browser on the personal terminal 2c.

  Further, in the present embodiment, the content is dragged and dropped from the shared operation display area 122c displayed on the personal terminal 2c to the personal operation display area 102c, but the present invention is not limited to this. For example, content may be dragged and dropped from the shared operation display area displayed on the personal terminal 2a or the personal terminal 2b to the personal operation display area. Further, the content may be dragged and dropped from the shared operation display area displayed on the shared terminal 4 to the shared operation display area.

(Details of processing or operation)
Subsequently, the details of the process or operation in the second embodiment will be described with reference to FIGS. 12 and 13. Here, the processing corresponding to FIGS. 7 to 10 will be described. 12 and 13 are sequence diagrams showing the copy process when the content to be copied is the entire screen. Here, the process (S103) after the above-mentioned precondition will be described in detail.

  First, when the user C specifies the content of the entire screen displayed on the operation display area 122c with the mouse 212 of the personal terminal 2c, the reception unit 22c receives the specification of the content of the entire screen (S141). Then, when the user C drags with the mouse 212, the reception unit 22c receives the drag of the content of the entire screen (S142). Then, the storage / read processing unit 29c temporarily stores the URL of the shared electronic screen ss corresponding to the drag on the clipboard of the storage unit 2000c (S143).

  Next, when the user C drops the content of the entire screen at a desired display position in the operation display area 102c with the mouse 212, the reception unit 22c receives the drop (S144). The image processing unit 23c acquires the display position information p3 indicating the position of the drop on the personal electronic campus dc3 by the web browser of the personal terminal 2c (S145). The storage / readout processing unit 29c reads out the URL of the shared electronic screen ss stored in the storage unit 2000c (S146). Then, the transmitting / receiving unit 21c transmits a content copy request (information thereof) to the content management server 6 by the web browser displaying the operation display area 102c (S147). This copy request includes the display position information p3 acquired in step S145 and the URL of the shared electronic screen ss read in step S146. As a result, the transmission / reception unit 61 of the content management server 6 receives the content copy request.

  Next, the content management server 6 determines the content of the content copy request (S148). This determination is the same as step S48 in the first embodiment and the processing shown in FIG. Since the content ID has not been received in step S147, the determination unit 65 determines that the request is a copy of the content data of the screen capture image (entire screen).

  Next, the storage / readout processing unit 69 reads out the content data of the entire screen from the storage unit 6000 based on the URL of the shared electronic screen ss (S149). The creation unit 63 of the content management server 6 newly creates the content ID 13 (S150). Then, the storage / read processing unit 69 creates the display position information p3 received in step S147, the content data of the entire screen read in step S49, and the creation in step S150 in the personal content management DB 6001. The created content ID 13 is associated and stored (S151). As a result, in the content management server 6, the content data is copied from the storage unit 6000 to the personal content management DB 6001. This data copy process corresponds to steps S105 and S106 in FIG. 11 showing the concept of the process.

  Steps S166 to S171 shown in FIG. 13 are the same processes as steps S66 to S71 in FIG. 10, except that the shared content management DB 6002 and the shared content management DB 2002c are changed to the individual content management DB 6001 and the individual content management DB 2001c. There is. More specifically, the transmission / reception unit 61 transmits an update notification, which is a notification to update the personal electronic campus, to the personal terminal 2c (S166). When the user C has a plurality of personal terminals and accesses the same personal electronic campus (URL) from each, the content management server 6 updates the plurality of personal terminals of the user C. Send a notification. As a result, the transmission / reception unit 21c receives the update notification by the web browser that displays the operation display area 102c of the personal terminal 2c.

  Next, the transmission / reception unit 21c transmits (request) the updated content data and display position information request to the content management server 6 by the web browser displaying the operation display area 102c of the personal terminal 2c. Yes (S167). As a result, the transmission / reception unit 61 of the content management server 6 receives the updated request for content data and display position information.

  Next, in the content management server 6, the storage / read processing unit 69 reads the content ID 13 related to the updated content, the content data of the entire screen, and the display position information p3 from the personal content management DB 6001 (S168). Then, the transmission / reception unit 61 transmits the content ID 13, the content data of the entire screen, and the display position information p3 to the personal terminal 2c (S169). As a result, the transmission / reception unit 21c receives the content ID 13, the content data of the entire screen, and the display position information p3 by the web browser of the personal terminal 2c.

  Next, in the personal terminal 2c, the storage / readout processing unit 29c stores the content ID 13, the content data, and the display position information p3 received in step S169 in association with each other in the personal content management DB 2001c (S170). .. As a result, the display controller 24c updates the operation display area 102c to display the content, which is the entire screen, by the web browser of the personal terminal 2c (S171).

<Main effects of the embodiment>
As described above, according to the present embodiment, the user C of the personal terminal 2c can drag and drop the content of the entire screen from the operation display area 122c to the desired position of the operation display area 102c on the personal terminal 2c. By performing the copy operation, the content management server 6 performs screen capture, and data of the content of the entire screen can be data-copied to the personal content management DB 6001. In this way, if the user C performs a local operation (drag and drop) on the personal terminal 2c, the personal terminal 2c transmits the display position information of the content to be copied to the content management server 6, and therefore the personal terminal 2c. It is not necessary to transmit the content data of the entire screen, which has a relatively large data communication amount, from the content management server 6 to the content management server 6. As a result, the communication time can be shortened, and finally, it is possible to further shorten the time until the copied content is displayed on the operation display area 102c by the web browser of the personal terminal 2c.
