In FIG. 1, a conventional memo information system 5 includes a document information DB 1 in which document information 2 such as a Web page acquired in advance by a system administrator via a network is stored. For example, when the user requests the document information 2 stored in the document information DB 1 from the user terminal to the system 5, the document information 2 is read and displayed on the screen of the user terminal (step S1). The user enters memo information on the document information 2 displayed on the screen (step S2). Original information 4 reflecting memo information is displayed on original information 2 (step S3). When there is a storage request for the document information 4 displayed by the user, the document information 4 is stored in the document information DB 1 (step S4). On the other hand, when the user selects a predetermined delete button or the like, the document information 2 from which the memo information has been deleted is displayed (step S5). Further, when the original information is displayed after finishing the one-end processing, the original information 4 to which the memo information stored at the original information DB1 is added is displayed (step S6).
[0004]
In addition, there is a conventional technique in which an electronic memo acquired by a display-integrated tablet for displaying an electronic memo on a virtual transparent input sheet is stored in a storage device in association with a target document (for example, patent document) 1).
[0005]
Furthermore, when the worker examines the contents of the meeting later, there is a conventional technique for reproducing the contents of the window and confirming the creation status of the contents written in the personal window during the meeting (for example, Patent Document 2). reference).
[0006]
In addition, there is a conventional technique for semi-automatically performing preparatory work required for holding a conference such as management of digitized conference materials, creation of a conference table of contents, and automatic distribution of conference materials (see, for example, Patent Document 3).
[0007]
In addition, the notes entered by the presenter are stored as accumulated memo data on the server, and the notes of the conference participants are stored locally, so that the notes created by the presenter are displayed on the screen of the conference participants. There is a conventional technique for displaying the memo only on its own screen (see, for example, Patent Document 4).

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0031]
FIG. 2 is a configuration diagram of the display control system according to the embodiment of the present invention. In FIG. 2, the display control system 10 manages document information that is electronic data and memo information related to a memo input to the document information, and also controls a display control server 20 that controls the display of the memo. The system includes a plurality of user terminals 30 that the user owns and inputs memos to manuscript information. Further, the display control server 20 and a plurality of user terminals 30 are connected via the network 1 which is a public line network such as the Internet. The display control server 20 can also function as a lead user terminal.
[0032]
The display control server 20 shown in FIG. 2 is a server computer, and each component shown below is controlled by a CPU (central processing unit). The CPU performs processing in the display control system 10 according to a program stored in the memory unit. The display control server 20 mainly includes a synchronization control unit 21 that controls to synchronize the display of document information and memos, an encryption unit 22 that encrypts document information and memo information to be transmitted, and document information and memo information. Pager control means 31 for performing control such as synchronizing the position when scrolling the screen on which is displayed, memo information management means 23 for controlling display of the memo based on the memo information, and memo level based on the memo information Memo display control means 32 for controlling display data corresponding to the terminal, terminal control means 24 for controlling transmission / reception data to / from the user terminal 30, communication control means 25 for controlling data communication such as transmission / reception of electronic mail, Information control means 29 for controlling the display of document information and memos on other user terminals 30 and definition information for managing definition information defined for the user terminal 30 Management means 33, campus information management means 34 for managing manuscript information such as Web page screen copy and document information, user definition DB 26 in which definition information is stored, and memo information related to a memo entered in the manuscript information. It consists of a stored memo information DB 27 and a document information DB 28 in which document information is stored. FIG. 13 shows part of the table stored in the memo information DB 27, FIG. 14 shows part of the table stored in the user definition DB 26, and FIG. 23 shows the structure of the memo information and definition information in detail. explain.
[0033]
The synchronization control unit 21 performs control to synchronize the display of the document information and the memo transmitted to the user terminal 30 and provides control data to the information control unit 29. The encryption unit 22 encrypts the document information and the memo information to be transmitted to the user terminal 30 and provides the encrypted data to the memo information management unit 23. The encryption unit 22 has a function of decrypting the encrypted document information and memo information received from the user terminal 30. It should be noted that the encryption means 22 does not have permission from the display control server 20 for the manuscript information and the memo information used in the electronic conference when the electronic conference or the like is completed or agreed by the member conducting the electronic conference. As long as it is encrypted, it cannot be changed by other members of the destination. Specifically, the campus information (manuscript information, memo information, etc.) stored in chronological order after the meeting is ended by the encryption means 22 of the display control server 20 using the system secret key, and the users of the meeting participants are encrypted. The campus information decrypted with the system public key can be browsed by the encryption means 22 of the side terminal 30. In addition, the encryption means 22 of the user terminal 30 of the conference participant uses the hash function to hash, and the encrypted document information and memo information are falsified as compared with the hashing when the system encrypts. Can be used as minutes and evidence.
[0034]
The pager control means 31 provides the memo information management means 23 with control data for performing display control such as synchronizing the position when the screen is scrolled based on the document information and the memo information. The memo display control means 32 receives the control information generated based on the definition information stored in the user definition DB 26, the memo information stored in the memo information DB 27 and the control data transmitted from the display control server 20. This is provided to the management means 23. The definition information management means 33 stores definition information defined for the user terminal 30 in the user definition DB 26 and manages the definition information. The campus information management unit 34 stores and manages document information such as screen copies of web pages and document information in the document information DB 28. If there is no need to pay attention to manuscript information management because the web page cannot be updated, the URL information may be managed instead of the screen copy of the web page.
[0035]
The memo information management means 23 stores control data for controlling the display of memos of other user side terminals 30 based on the memo information stored in the memo information DB 27 and the definition information stored in the user definition DB 26. This is provided to the information control means 29. The terminal control unit 24 provides the communication control unit 25 with control data for controlling data transmission / reception to the corresponding user terminal 30 based on the definition information stored in the user definition DB 26. The communication control unit 25 includes a communication unit that controls transmission / reception of data through the network 1, and transmits document information and memo information stored in the document information DB 28 to a predetermined user terminal 30 based on the control data.
[0036]
Moreover, since the user side terminal 30 is the same structure as the display control server 20, it attaches | subjects a same sign and abbreviate | omits description. In addition, when display control is performed via the display control server 20 or the lead user side terminal 20, the configuration indicated by the broken line in the user side terminal 30 (user definition DB 26, definition information management means 33, terminal control) It is assumed that the means 24, the information control means 29, the campus information management means 34, and the manuscript information DB 28) do not function.
[0037]
Next, the principle of memo information will be described. FIG. 3 is a diagram for explaining the principle of memo information. In FIG. 3, the campus 110 displayed on the display unit in the user side terminal 30 is composed of a Web page 101 acquired from the Web server 100 and original information 102 stored in the original information DB 28 in advance. The campus 110 has a virtualized transparent sheet 111 function, and a memo is input to the transparent sheet 111. For example, the Web page 101 is referred to by the browser by the display control server 20 (step S1). The referenced web page 101 is pasted on the campus 110 by drag and drop, and at the same time, the location of the web page 101 (for example, URL (Uniform Resource Locator)) is recorded (step S2). Further, the document information 102 stored in advance in the document information DB 28 is pasted on the campus 110 by drag and drop, and at the same time, the location (address) of the document information 102 is recorded (step S3). Next, a memo is input on the transparent sheet 111 of the campus 110 (step S4). The location of each manuscript on the campus 110 is stored in the memo information DB 27 together with the memo information regarding the input memo.
[0038]
As described above, by managing the location of the document information together with the memo information separately from the document information, the document information and the memo information can be effectively used.
[0039]
Next, the procedure of display control processing for managing memo information related to memos input at the user terminal 30 via the display control server 20 will be described. FIGS. 4-6 is a figure which shows the flowchart in the display control process performed via a display control server. First, the communication control means 25 of the user terminal 30 waits for an event from the display control server 20 in the process of step S10 shown in FIG. In the process of step S <b> 11, the communication control unit 25 determines whether an input event has occurred and the input information is notification information from the display control server 20. If it is determined in step S11 that the information is not notification information from the display control server 20, in step S12, the communication control unit 25 determines whether the input information is a connection request for performing communication in real time. to decide. If it is determined in step S12 that the input information is a connection request, in step S13, the communication control means 25 connects to the display control server 20 and returns to step S10. If it is determined in step S12 that the input information is not a connection request, in step S14, the communication control unit 25 determines whether the input information is a request for disconnecting from the display control server 20. To do. If it is determined in step S14 that the input information is a disconnection request, the communication control unit 25 disconnects the connection with the display control server 20 in step S15, and the process returns to step S10.
[0040]
If it is determined in step S14 that the input information is not a disconnection request, in step S16, the memo information management unit 23 determines whether there is a memo input. If there is a memo input in the process of step S16, the memo information management means 23 stores the memo in the memo information DB 27 and the communication control means 25 notifies the display control server 20 of the memo information in the process of step S17. To do. Next, in the process of step S18, the memo information management unit 23 displays the memo on the transparent sheet, and returns to the process of step S10. If no memo is input in the process of step S16, the memo information management unit 23 determines whether the input information is a save request in the process of step S19. If it is determined in step S19 that the input information is a save request, in step S20, the communication control unit 25 notifies the display control server 20 of the save request, and the process returns to step S10. When it is determined in step S19 that the input information is not a save request, in step S21, the memo information management unit 23 determines whether a memo stored in the memo information DB 27 has been searched. When a memo is retrieved in the process of step S21, the memo information management means 23 extracts a memo that matches the search condition, highlights the memo in the process of step S22, and returns to the process of step S10.
[0041]
If no memo is found in the process of step S21, the pager control means 31 determines whether or not the screen has been scrolled in the process of step S23 shown in FIG. When the screen is scrolled in the process of step S23, the communication control unit 25 notifies the display control server 20 of the scroll information in the process of step S24. In the process of step S25, the pager control means 31 scrolls the document and the memo displayed on the screen, and returns to the process of step S10. If the screen is not scrolled in the process of step S23, the memo information management unit 23 determines whether or not the memo has been deleted in the process of step S26. When the memo is deleted in the process of step S26, the communication control means 25 requests the display control server 20 to delete the memo (all memos or latest memo) in the process of step S27. In the process of step S28, the memo information management unit 23 redisplays the screen from which the memo has been deleted, and returns to the process of step S10.
[0042]
If the memo is not deleted in the process of step S26, the pager control means 31 determines whether or not a document is newly set in the process of step S29. If a new document is set in step S29, the communication control means 25 notifies the display control server 20 of the address that is the location of the document information in step S30, and the process returns to step S10. If a new document is not set in step S29, the memo display control means 32 determines whether or not the display memo level is set in step S31. If the display memo level is set in the process of step S31, the memo information management means 23 displays the memo again according to the memo level in the process of step S32, and returns to the process of step S10. If the display memo level is not set in step S31, the memo display control means 32 determines whether a new memo level is set in step S33. If a new memo level is set in step S33, the memo display control means 32 stores the set memo level in the memo information DB 27 in step S34, and the process returns to step S10.
[0043]
If a new memo level is not set in step S33, the memo display control means 32 determines in step S35 whether or not a memo type has been set. When the memo type is set in the process of step S35, the memo display control means 32 determines whether or not the set memo type is graphic in the process of step S36. If the set memo type is graphic in step S36, the memo display control means 32 stores the set memo type (graphic) in the memo information DB 27 in step S37, and step S10. Return to the process. If the set memo type is not graphic in the process of step S36, the memo display control means 32 stores the set memo type (character) in the memo information DB 27 in the process of step S37. Return to processing.
[0044]
When the type of memo is not set in the process of step S35, the memo display control means 32 determines whether or not the color of the input memo is set in the process of step S39 shown in FIG. If the color of the input memo is set in step S39, the memo display control means 32 stores the set color type (RGB) in the memo information DB 27 in step S40, and step S10. Return to the process. If the color of the input memo is not set in the process of step S39, the memo display control means 32 determines whether or not the font is set in the process of step S41. If no font is set in step S41, the process returns to step S10. If the font is set in the process of step S41, the memo display control means 32 determines whether or not the requester's memo type is a character in the process of step S42. If the requester's memo type is a character in step S42, the memo display control means 32 stores the character font in the memo information DB 27 in step S43, and the process returns to step S10. If the requester's memo type is not a character in the process of step S42, the memo display control means 32 stores the pen thickness in the memo information DB 27 in the process of step S44, and returns to the process of step S10.
[0045]
If it is determined in step S11 shown in FIG. 4 that the input information is not a notification request from the display control server 20, the communication control means 25 notifies the display control server 20 of a memo in step S45. Judge whether there is. If it is determined in step S45 that there is a memo notification from the display control server 20, in step S46, the memo information management unit 23 records the memo in the memo information DB 27 and displays a display document on the transparent sheet. When notified, the document is displayed, and the process returns to step S10. If it is determined in step S45 that there is no memo notification from the display control server 20, the communication control means 25 determines whether there is a memo deletion notification from the display control server 20 in step S47. . If it is determined in step S47 that there is a memo deletion notification from the display control server 20, in step S48, the memo information management unit 23 deletes the displayed memo and displays the screen from which the memo has been deleted. The information is displayed again, and the process returns to step S10.
[0046]
As described above, the user terminal 30 manages the memo information regarding the location of the manuscript information and the input memo, displays the memo according to the memo level, and controls a plurality of user sides under the control of the display control server 20. The document information and the memo can be synchronized and displayed on the screen by the terminal 30.
[0047]
Next, a display control process procedure for managing memo information by the display control server 20 will be described. 7 and 8 are flowcharts showing display control processing executed by the display control server. First, in the process of step S50 shown in FIG. 7, the communication control means 25 of the display control server 20 waits for an event from the user terminal 30. In the process of step S51, the communication control unit 25 determines whether or not the input information is a connection request for performing communication in real time. If it is determined in step S51 that the input information is a connection request, in step S52, the communication control unit 25 connects to a predetermined user terminal 30 and the definition information management unit 33 The definition information about the requester is stored in the requester definition DB 26, and the document information and the memo information are notified to the requester, and the process returns to step S50. If it is determined in step S51 that the input information is not a connection request, in step S53, the communication control unit 25 determines whether the input information is a request for disconnecting the connection with the user terminal 30. to decide. If it is determined in step S53 that the input information is a disconnection request, the communication control unit 25 disconnects the connection with the user terminal 30 in step S54, and the definition information management unit 33 The information on the requester stored in the definition DB 26 is deleted, and the process returns to step S50. If it is determined in step S53 that the input information is not a disconnection request, in step S55, the memo information management unit 23 determines whether a memo is requested from the requester. If a memo is requested from the requester in the process of step S55, the memo information management means 23 stores the memo in the memo information DB 27 and the communication control means 25 is not a memo requester in the process of step S56. The memo is notified to all users, and the process returns to step S50.
[0048]
If the requester does not request a memo in step S55, the memo information management unit 23 determines whether the input information is a save request from the user terminal 30 in step S57. If it is determined in step S57 that the input information is a save request from the user terminal 30, in step S58, the memo information management unit 23 determines whether the save request is a document setter. to decide. If the save request is not a manuscript setting person in step S58, the process returns to step S50. If the save request is a document setter in step S58, the encryption unit 22 encrypts the document information and the memo in step S59, and the memo information management unit 23 stores the document information DB 28 and the memo information DB 27. In step S50, the encrypted data is stored. If it is determined in step S57 that the input information is not a save request from the user side terminal 30, the memo information management unit 23 receives the input information from the user side terminal 30 in step S60. It is determined whether or not. If it is determined in step S60 that the input information is a document setting request from the user terminal 30, the memo information management unit 23 determines whether document setting is possible in step S61. To do. If the document setting is not possible in the process of step S61, the process returns to the process of step S50. If the document setting is possible in the process of step S61, the encryption means 22 stores the address indicating the location of the document and the setter in the memo information DB 27 in the process of step S62, and sets the document setting impossible state. Then, the process returns to step S50.
[0049]
If it is determined in step S60 that the input information is not a document setting request from the user terminal 30, the communication control unit 25 determines that the input information is on the user side in step S63 shown in FIG. It is determined whether or not it is a screen scroll request from the terminal 30. When it is determined in step S63 that the input information is a screen scroll request, in step S64, the communication control unit 25 notifies the scroll information to all users other than the requester, and in step S50. Return to processing. If it is determined in step S63 that the input information is not a screen scroll request, in step S65, the memo information management unit 23 determines whether the input information is a memo deletion request from the user terminal 30. Determine whether. If it is determined in step S65 that the input information is a memo deletion request, in step S66, the memo information management unit 23 determines whether the input information is requested to be deleted from the user terminal 30. Judge whether or not. If it is determined in step S66 that the input information is all memo deletion requests, in step S67, the memo information management unit 23 deletes the requester's memos (all memos or latest memos) and performs communication control. The means 25 notifies the memo deletion result to all users other than the deletion requester, and returns to the process of step S50. If it is determined in step S65 that the input information is not a memo deletion request, or if it is determined in step S66 that it is not all memo deletion requests, the process returns to step S50.
[0050]
In this way, the display control server 20 manages definition information, manuscript information, and memo information that define a user in response to a request from the user side terminal 30, and manuscript information displayed on the user side terminal 30. In addition, the memo can be controlled and the management result can be notified to the plurality of user terminals 30.
[0051]
Next, the procedure of display control processing for managing memo information among a plurality of user terminals 30 will be described. 9 to 12 are flowcharts showing display control processing executed only by the user terminal. First, in the process of step S <b> 70 shown in FIG. 9, the communication control unit 25 of the user side terminal 30 waits for an event from another user side terminal 30. In the process of step S <b> 71, the communication control unit 25 determines whether there is information notification from another user terminal 30. If it is determined in step S71 that there is no notification from the other user side terminal 30, the communication control means 25 performs communication in real time from the other user side terminal 30 in step S72. It is determined whether or not the request is a connection request. If it is determined in step S72 that the input information is a connection request, in step S73, the communication control unit 25 connects to another user terminal 30 and returns to step S70. If it is determined in step S72 that the input information is not a connection request, in step S74, the communication control means 25 determines whether or not the input information is a disconnection request for connection with another user terminal 30. Judging. If it is determined in step S74 that the input information is a disconnection request, the communication control unit 25 disconnects the connection with the other user terminal 30 in step S75, and the process returns to step S70. .
[0052]
If it is determined in step S74 that the input information is not a disconnection request, in step S76, the memo information management unit 23 determines whether there is a memo input. If there is a memo input in the process of step S76, the memo information management means 23 stores the memo in the memo information DB 27 in the process of step S77, and the communication control means 25 sends the memo to the other user side terminal 30. Notify information. Next, in the process of step S78, the memo information management unit 23 displays the memo on the transparent sheet, and returns to the process of step S70. If there is no memo input in step S76, the memo information management unit 23 determines whether the input information is a save request in step S79. If it is determined in step S79 that the input information is a save request, the communication control unit 25 notifies the other user side terminal 30 of the save request in step S80. In step S81, the encryption unit 22 encrypts the document information and the memo, and the campus information management unit 34 stores the encrypted data in the document information DB 28, and the process returns to step S70. If it is determined in step S79 that there is no save request, in step S82, the memo information management unit 23 determines whether the memo stored in the memo information DB 27 has been searched. If a memo is searched in the process of step S82, the memo information management means 23 extracts a memo that matches the search condition, highlights the memo in the process of step S83, and returns to the process of step S70.
[0053]
When the memo is not searched in the process of step S82, the pager control means 31 determines whether or not the screen is scrolled in the process of step S84 shown in FIG. When the screen is scrolled in the process of step S84, the communication control means 25 notifies the other user side terminal 30 of the scroll information in the process of step S84. In step S86, the pager control means 31 scrolls the document and the memo displayed on the screen, and returns to step S70. If the screen is not scrolled in step S84, the memo information management unit 23 determines whether the memo has been deleted in step S87. When the memo is deleted in the process of step S87, the communication control means 25 requests the other user side terminal 30 to delete the memo (all memos or latest memo) in the process of step S88. In the process of step S89, the memo information management unit 23 redisplays the screen from which the memo has been deleted, and returns to the process of step S70.
[0054]
If the memo is not deleted in the process of step S87, the pager control means 31 determines whether or not a new document is set in the process of step S90. When a new document is set in the process of step S90, the communication control means 25 notifies the address of the location of the document information to the other user terminal 30 in the process of step S91, and the process proceeds to step S70. Return. If a new document is not set in step S90, the memo display control unit 32 determines whether or not the display memo level is set in step S92. If the display memo level is set in the process of step S92, the memo information management means 23 displays the memo again according to the memo level in the process of step S93, and returns to the process of step S70. If the display memo level is not set in step S92, the memo display control means 32 determines whether or not a new memo level is set in step S94. If a new memo level is set in the process of step S94, the memo display control means 32 stores the set memo level in the memo information DB 27 in the process of step S95, and returns to the process of step S70.
[0055]
If a new memo level is not set in the process of step S94, the memo display control means 32 determines whether or not a memo type is set in the process of step S96. When the memo type is set in the process of step S96, the memo display control means 32 determines whether or not the set memo type is graphic in the process of step S97. If the set memo type is graphic in step S97, the memo display control means 32 stores the set memo type (graphic) in the memo information DB 27 in step S98, and step S70. Return to the process. If the set memo type is not graphic in the process of step S97, the memo display control means 32 stores the set memo type (character) in the memo information DB 27 in the process of step S99. Return to processing.
[0056]
If the type of memo is not set in step S96, the memo display control means 32 determines whether or not the color of the input memo is set in step S100 shown in FIG. If the color of the input memo is set in step S100, the memo display control means 32 stores the set color type (RGB) in the memo information DB 27 in step S101, and step S70. Return to the process. If the color of the input memo is not set in the process of step S100, the memo display control means 32 determines whether or not the font is set in the process of step S102. If no font is set in step S102, the process returns to step S70. If the font is set in the process of step S102, the memo display control means 32 determines whether or not the requester's memo type is a character in the process of step S103. If the requester's memo type is a character in the process of step S103, the memo display control means 32 stores the character font in the memo information DB 27 in the process of step S104, and returns to the process of step S70. If the requester's memo type is not a character in the process of step S103, the memo display control means 32 stores the pen thickness in the memo information DB 27 in the process of step S105, and returns to the process of step S70.
[0057]
Further, when it is determined in step S71 shown in FIG. 9 that there is no notification from the other user side terminal 30, the communication control means 25 is connected to another user side in step S106 shown in FIG. It is determined whether the input information from the terminal 30 is a connection request for performing communication in real time. If it is determined in step S106 that the input information is a connection request, in step S107, the communication control unit 25 connects to another user terminal 30 and returns to step S70. If it is determined in step S106 that the input information is not a connection request, in step S108, the communication control means 25 determines whether the input information from the other user terminal 30 is a memo notification request. Judging.
[0058]
If it is determined in step S108 that the input information is a memo notification request, in step S109, the memo information management unit 23 records the memo in the memo information DB 27 and notifies the display sheet of the display document on the transparent sheet. The original is displayed, and the process returns to step S70. If it is determined in step S108 that the input information is not a memo notification request, in step S110, the communication control means 25 determines whether the input information from the other user terminal 30 is a memo deletion notification request. Judge whether or not. If it is determined in step S110 that the input information is a memo deletion notification request, in step S111, the memo information management unit 23 deletes the displayed memo and redisplays the screen from which the memo has been deleted. Then, the process returns to step S70.
[0059]
If it is determined in step S110 that the input information is not a memo deletion notification request, in step S112, the communication control means 25 determines whether the input information is a disconnection request for connection with another user terminal 30. Judge whether or not. If it is determined in step S112 that the input information is a disconnection request, the communication control unit 25 disconnects the connection with the other user terminal 30 in step S113, and the process returns to step S70. . If it is determined in step S112 that the input information is not a disconnection request, in step S114, the memo information management unit 23 determines whether the input information is a save request. If it is determined in step S114 that the input information is a save request, the encryption unit 22 encrypts the document information and the memo in step S115, and the campus information management unit 34 stores the document information in the document information DB 28. The encrypted data is stored, and the process returns to step S70. If it is determined in step S114 that the input information is not a save request, the process returns to step S70.
[0060]
In this way, each user terminal 30 manages the document information and memo information, displays the memo according to the memo level, and synchronizes the document information and memo between the plurality of user terminals 30 and displays the screen. Can be displayed.
[0061]
Next, the memo level table stored in the memo information DB 27 will be described. FIG. 13 is a diagram showing a memo level table stored in the memo information DB. In FIG. 13, a memo level table 270 indicates memo levels set for memos input by a user or the like. The memo level table 270 stores an item indicating a user ID for identifying a user who has input a memo, an item indicating the memo input by the user, and an item indicating the memo level for the memo. . Here, when the memo level is “0”, it indicates that the memo can be referred to by all users. When the memo level is “1”, only a predetermined user or a user in a predetermined group refers to the memo. This indicates that the memo is a memo, and when the memo level is “2”, it indicates that the memo can be referred to only by the user who has input the memo. For example, a memo “AAA” and a memo level “0” are stored for the user ID “U1”. Since the memo level “0” is stored, the memo “AAA” with the user ID “U1” can be referred to by all users.
[0062]
Next, the definition table stored in the user definition DB 26 will be described. FIG. 14 is a diagram showing a definition table stored in the user definition DB. In FIG. 14, a definition table 260 shows memo levels set for memos input by a user or the like. The definition table 260 stores an item indicating the name of the user who inputs the memo, an item indicating the user ID for identifying the user, and an item indicating the group ID that classifies the referenceable users. . For example, when the group ID of the user who refers to the memo is the same as the group ID of the user who has input the memo and the memo level of the memo is “1” or lower, the user who refers to the memo refers to the memo. It becomes possible. For example, the definition table 260 stores a user name “user A”, a user ID “U1”, and a group ID “G1”. Therefore, according to this definition table 260, when user A refers to a memo of another user, if the user who inputs the memo is the group ID “G1” and the memo level “1” of the memo is below: You can refer to the memo.
[0063]
Next, the relationship between the memo creator and the memo referer will be described. FIG. 15 is a diagram for explaining the relationship between the memo creator and the memo referer. A table 277 shown in FIG. 15 shows a relationship between a memo creator and a memo reference person based on the memo level table 270 shown in FIG. 13 and the definition table 260 shown in FIG. In Table 277, when the memo referer can refer, it is represented by “「 ”, and when the memo referer cannot refer, it is represented by“ x ”. For example, in the table 277, when the user A himself refers to the memo of the user A who is the memo creator, all the memos can be referred to. When user B of group ID “G1” refers to the memo of user A of group ID “G1” who is the memo creator, user B belongs to the same group as user A, and therefore the memo level is “ 1 ”You can refer to the notes below. Further, when the user C with the group ID “G3” refers to the memo of the user A with the group ID “G1” who is the memo creator, the user C belongs to a different group from the user A, so the memo level Only notes with "0" can be referenced.
[0064]
Next, the memo information output process in the display control process will be described. FIG. 16 is a diagram for explaining the memo information output process. In FIG. 16, the display control server 20 has a document information 280 stored in the document information DB 28 and a memo stored in the memo information DB 27 in a predetermined user terminal 30 based on the definition information stored in the user definition DB 26. A predetermined memo is provided from the information 275. The user terminal 30 controls the memo information to be output based on the memo level table 270 shown in FIG. 13 and the definition table 260 shown in FIG. Here, the document information 280 is the document information “Aiueo”, and the memo information 275 is the memo “AAA”, “BBB”, and “CCC”. For example, since the user A can refer to all memo levels by using the definition table 260, the campus 200 of the user terminal 30 of the user A has manuscript information “Aiueo” and memo “AAA” as campus information. , “BBB”, “CCC” are displayed. Campus information is information that constitutes the campus. Here, URL is not used as campus information, but only document information or memo information is explained, but URL information and image information are included. Of course, this is also assumed.
[0065]
Also, since user C can refer to the memo “AAA” set to memo level “0” by the definition table 260 and the memo entered by the user C, the user C can access the campus 201 of the user terminal 30 of the user C. Is displayed with document information “Aiueo” and notes “AAA” and “CCC”.
[0066]
Here, in the user terminal 30 of the user A, when the memo is set to “on” by a predetermined setting means, the manuscript information “Aiueo” and the memos “AAA”, “BBB”, “CCC” The output result 205 is output from a display or the like. Further, when the memo is set to “on” and the memo level is set to “2” or higher on the user-side terminal 30 of the user A by the predetermined setting means, the document information “Aiueo” and the memo level are set. A memo “CCC” set to “2” or more is output as an output result 206 on a display or the like. When the user terminal 30 of the user A sets the memo to “on” by a predetermined setting means and sets the memo level to “1” or higher, the document information “Aiueo” and the memo level are “1”. The memos “BBB” and “CCC” set above are output as an output result 207 by a display or the like. When the memo is set to “on” by the predetermined setting means and the memo level is set to “0” on the user terminal 30 of the user A, the manuscript information “Aiueo” and the memo level is “0”. The memo “AAA” set as described above is output as an output result 208 by a display or the like. When the user A terminal 30 of the user A sets the memo to “off” by a predetermined setting means, only the document information “Aiueo” is output as an output result 209 on the display or the like.
[0067]
On the other hand, when the memo is set to “on” or the memo is set to “on” by the user terminal 30 of the user C and the memo level is set to “2” or higher, the document information “ “Aiueo” and memo “CCC” are output as an output result 206 on a display or the like. In the user terminal 30 of the user C, when the memo is set to “off”, the memo is set to “on”, and the memo level is set to “1” by a predetermined setting unit, only the manuscript information “Aiueo” is stored. The output result 209 is output by a display or the like.
[0068]
In this way, by setting the memo output on / off by a predetermined setting means at the user side terminal 30 and setting the memo level and performing the output process, an output result corresponding to the setting can be obtained. it can.
[0069]
Next, the time stamp table stored in the memo information DB 27 will be described. FIG. 17 is a diagram showing a time stamp table stored in the memo information DB. In FIG. 17, the time stamp table 272 stores time stamps that are history information regarding the date and time when a memo was input by a user or the like. The time stamp table 272 stores an item indicating the memo input by the user, an item indicating the name of the user who input the memo, and an item indicating the time stamp indicating the date and time when the memo is input. For example, the time stamp table 272 stores a user name “user A” and a time stamp “2003/02/01/12: 00: 00” for the memo “AAA”. The memo “AAA” is input by the user A and indicates that it was input at 12:00 on February 1, 2003.
[0070]
Next, a memo information search process in the display control process will be described. FIG. 18 is a diagram for explaining the memo information search process. In FIG. 18, the display control server 20 has a document information 280 stored in the document information DB 28 and a memo stored in the memo information DB 27 in a predetermined user terminal 30 based on the definition information stored in the user definition DB 26. A predetermined memo is provided from the information 276. The user terminal 30 searches for a predetermined memo based on the time stamp table 272 shown in FIG. 17, and the search result is displayed on the screen. Here, the document information 280 is the document information “Aiueo”, and the memo information 276 is the memo “AAA”, “BBB”, “CCC”, and “DDD”. For example, since the user A can refer to all memo levels by the definition table 260, the document information “Aiueo”, memos “AAA”, “BBB” are stored in the campus 210 of the user terminal 30 of the user A. ”,“ CCC ”, and“ DDD ”are displayed.
[0071]
Here, in the user terminal 30 of the user A, when the search process by the creation date and time is executed by a predetermined setting unit, the search results 211 to 213 are displayed on the screen. For example, when a memo input after the date “2003/02/01/12: 01” is searched, the original information “Aiueo” and the memos “BBB”, “CCC”, “DDD” are displayed as the search result 211. Is displayed. When a memo input before the date “2003/02/01/13: 00” is searched, the document information “Aiueo” and memos “AAA” and “BBB” are displayed on the screen as the search result 212. . When a memo input from the date “2003/02/01/12: 05” to the date “2003/02/01/12: 15” is searched, the document information “Aiueo” and the memo “BBB” are displayed. The search result 213 is displayed on the screen.
[0072]
On the other hand, when the user A's terminal 30 executes a search process by the memo creator by a predetermined setting means, the search result 214 is output to the screen. For example, when a memo input by the user name “User A” is searched, the document information “Aiueo” and memos “AAA” and “DDD” are displayed on the screen as the search result 214.
[0073]
As described above, the user terminal 30 can display the memo searched based on the predetermined condition by performing the search process by the creation date and time or the memo creator by the predetermined setting means. In the search process, for example, a plurality of memos input from the conference start time to the end time may be searched in time series and displayed on the screen.
[0074]
Next, the creator display process of memo information in the display control process will be described. FIG. 19 is a diagram for explaining the memo information creator display process. In FIG. 19, the display control server 20 has a document information 280 stored in the document information DB 28 and a memo stored in the memo information DB 27 in a predetermined user terminal 30 based on the definition information stored in the user definition DB 26. A predetermined memo is provided from the information 276. The user terminal 30 displays the creator of the selected memo based on the time stamp table 272 shown in FIG. Here, the document information 280 is the document information “Aiueo”, and the memo information 276 is the memo “AAA”, “BBB”, “CCC”, and “DDD”. For example, since the user A can refer to all memo levels by the definition table 260, the document information “Aiueo”, memo “AAA”, “BBB” is stored in the campus 215 of the user terminal 30 of the user A. ”,“ CCC ”, and“ DDD ”are displayed.
[0075]
Here, when a predetermined memo is selected on the user terminal 30 of the user A and the creator display process is executed by a predetermined setting unit, display results 216, 218, and 220 are displayed on the screen. For example, when the memo “AAA” or the memo “DDD” is selected and the creator display process is executed, the memo “AAA” or the memo “DDD” selected on the campus 215 can be distinguished from other memos. In addition to being displayed in a display format (such as italics), it is displayed on the screen as a display result 216 having a display area 217 indicating the user name “user A” who entered the selected memo. When the memo “BBB” is selected and the creator display process is executed, the memo “BBB” selected on the campus 215 is displayed and selected in a display format distinguishable from other memos. Displayed on the screen as a display result 218 having a display area 219 indicating the user name “user B” who entered the memo. When the memo “CCC” is selected and the creator display process is executed, the memo “CCC” selected on the campus 215 is displayed and selected in a display format distinguishable from other memos. Is displayed on the screen as a display result 220 having a display area 221 indicating the user name “user C” who entered the memo.
[0076]
As described above, by selecting a predetermined memo and performing the creator display process on the user side terminal 30, the selected memo is highlighted and displayed in a display format that can be distinguished from other memos, and the selected memo is displayed. The user who created the can be displayed on the screen.
