  The present invention relates to an electronic conference system in which all conference participants share the same shared document on the screens of their respective terminal devices to realize the progress of the conference, an information processing device that constitutes the electronic conference system, an information processing method, and a program About.

  An electronic device that realizes a paperless meeting by simultaneously displaying shared documents such as meeting materials that are simultaneously viewed by meeting participants during a meeting or presentation on the screens of multiple terminal devices installed for each meeting participant. A conference system is known. There is also known an electronic conference system having a shared memo function that enables electronic memo writing on a shared document displayed on a screen of a terminal device. In the electronic conference system having this shared memo function, input devices such as a touch screen, a pen, a pen input tablet, and a mouse are connected to the terminal device, and the conference participants operate these input devices, Electronic memos can be freely written on the shared document displayed on the screen of the terminal device used by the user. The memo image written in the shared document being displayed on the terminal device is transmitted to the terminal device of another conference participant and displayed on the display unit of the terminal device. Therefore, each conference participant can view the memo image written by the other conference participants on his / her terminal device. In this way, the memo image that each conference participant writes to the shared document is shared among the conference participants in the same way as the shared document. Therefore, each conference participant uses the memo to share it. You can communicate your opinions on the content of the document to other conference participants.

  On the other hand, after the conference ends, the conference participants save the shared document with the memo image in an information processing device such as a server so that others can view the shared document with the memo image via the network. Keep it. Thereby, the conference participant can separately acquire a shared document with a memo image from the information processing apparatus via the Internet or an intranet network, and can confirm the content of the conference (for example, refer to Patent Document 1).

Japanese Patent Laid-Open No. 2003-9107 JP 2005-130257 A

  Patent Document 1 describes an electronic conference system in which participants of a conference individually add memos to a shared document and store a distribution material file with a memo as an electronic document. In the document described in Patent Document 1, a distribution material file with a memo is created from display information obtained by superimposing the storage contents of the document information storage means and the storage contents of the memo storage means. In other words, the document described in Patent Document 1 is a distribution document with a memo as it is when the save icon is touched in a state where a memo written by a plurality of conference participants is displayed superimposed on a shared document. It is a configuration to save as a file. Since the memo-attached distribution material file is created and stored for each conference terminal used by each conference participant, the amount of the memo-attached distribution material file stored can be enormous. The memo-attached distribution material file is stored in the information processing apparatus as it is displayed without selecting memos written by a plurality of conference participants. Therefore, when a memo-attached distribution material is acquired from the information processing device that is the storage destination of the memo-distributed distribution material after the meeting is finished, and viewed or printed, the memos written by multiple people overlap at the same location in the distribution material. Therefore, there is a problem that it is difficult to interpret the memo. In addition, for a meeting participant who intends to release a distributed document with a memo, a plurality of memos may include a memo that the reader wants to keep private.

Hereinafter, in order to distinguish these two terminal devices, one terminal device is referred to as A terminal device 1 and the other terminal device is referred to as B terminal device 1.

  The A terminal device 1 and the B terminal device 1 receive image data for each page of the shared document 36 stored in the conference server device 3 from the conference server device 3, perform predetermined processing in the display processing unit 104, and output it to the display 114. To do. The predetermined processing in the display processing unit 104 is to arrange the image data of each page of the shared document 36 on the lowest layer of the display screen. As can be seen from FIG. 4, the image of the page written as “ABC” in the shared document 36 is arranged in the lowest layer of the display screen.

  In both the A terminal device 1 and the B terminal device 1, a memo can be written on the shared document 36 using the tablet 113 and the pointing device 130. The control unit 100 receives an input from the pointing device 130 via the input processing unit 103 and creates an image according to the input. In the following description, the created image is referred to as a “memo image”. The memo images created by the A terminal device 1 and the B terminal device 1 are arranged on the top layer of each display screen. In A terminal device 1, an image of “free curve” is arranged in the uppermost layer of the display screen, and in B terminal device 1, an image of “arrow” is arranged in the uppermost layer of the display screen.

  The A terminal device 1 and the B terminal device 1 transmit to the conference server device 3 write information 311 that is information related to the memo image created by each of the A terminal device 1 and the B terminal device 1. The writing information is, for example, information about the type, color, thickness, line type, fill, and other formats and coordinates of the objects included in the memo image.

  In the first embodiment, the conference server device 3 periodically stores the write information 311 transmitted by each of the A terminal device 1 and the B terminal device 1 in the temporary storage unit 31.

A memo image is placed. Similarly, the memo image created based on the writing information 311A of the A terminal device 1 is arranged in an intermediate layer between the lowest layer and the highest layer of the display screen of the B terminal device 1. At this time, an image for each page of the shared document 36 is arranged in the lowest layer of the display screen of the B terminal device 1, and the uppermost layer is created based on the writing information 311 B of the B terminal device 1. A memo image is placed.

  By creating an image based on the writing information 311 described above, the shared document 36 (ABC) arranged in the lowest layer of the display screen of the terminal device 1 is displayed on both the display screens of the A terminal device 1 and the B terminal device 1. On the image, a memo image created based on the writing information 311 of the other terminal device 1 is arranged. For example, on the display screen of the A terminal device 1, the image of the shared document 36 (ABC) is arranged in the lowest layer, and the memo image (arrow) created based on the writing information 311B of the B terminal device 1 is in the intermediate layer. An image (free curve) that is arranged and created based on the writing information 311A of the A terminal device 1 is arranged in the highest layer. On the other hand, on the display screen of the B terminal device 1, the image of the shared document 36 (ABC) is arranged in the lowest layer, and the image (free curve) created based on the writing information 311A of the A terminal device 1 is in the intermediate layer. The arranged image created based on the writing information 311B of the B terminal device 1 is arranged in the highest layer.

  Further, the A terminal device 1 and the B terminal device 1 call information indicating which image or page in the shared document 36 is displayed (hereinafter referred to as “browsing information 312A” and “312B”). .) To the conference server device 3. The conference server device 3 stores the browsing information 312A and the browsing information 312B in the temporary storage unit 31. Thereby, the conference server device 3 can grasp which page of the shared document 36 is displayed on each terminal device. And the conference server apparatus 3 can display the shared document 36 in all the terminal devices 1a-1f synchronously. The stored display information may be information regarding an image in which images arranged in each layer in each terminal device 1 are superimposed.

  As described above, the shared document 36 is shared between the A terminal device 1 and the B terminal device 1, and each conference participant who uses the A terminal device 1 and the B terminal device 1 on the shared document 36 on the display screen. The memo image created by is displayed. Therefore, each conference participant who uses the A terminal device 1 and the B terminal device 1 can browse the memo images written by other conference participants while viewing the same shared document 36 at the same time.

  A conference participant who uses the A terminal device 1 can view a memo image written by himself / herself using the tablet 113 on the display 114. On the other hand, the writing information 311 A corresponding to the memo image is transmitted to the B terminal device 1 via the conference server device 3. The B terminal device 1 creates a memo image based on the writing information 311A and causes the display 114 to display the memo image.

  FIG. 5 is an explanatory diagram illustrating an example of the conference terminal application screen 400 displayed on the display 114 of the terminal device 1. As an example, the conference terminal application screen 400 includes a shared screen 401 that displays an image of the shared document 36 at substantially the center. In the example illustrated in FIG. 5, the one-page image 402 is reduced as necessary so that the entire one-page image 402 of the shared document 36 is displayed on the shared screen 401. A previous page button 403 for instructing movement of the shared document 36 to the previous page is displayed at a position at the left end of the substantially center in the height direction of the shared screen 401. Similarly, a rear page button 404 for instructing to move to the rear page (next page) of the shared document 36 is displayed at the rightmost position at the center in the height direction of the shared screen 401. On the right side of the shared screen 401, various operation buttons for selecting a tool for drawing a memo are displayed. The various operation buttons include a color or thickness selection button 408, an eraser button 409, a graphic button 410, an object selection button 411, a zoom button 412 and a synchronous / asynchronous button 413.

(In a meeting)
FIG. 7 is a flowchart illustrating an example of a display processing procedure during a meeting of the terminal device 1 in the electronic conference system according to the first embodiment.

  The control unit 100 in the terminal device 1 receives the shared document 36 from the conference server device 3 via the network 2, the network I / F unit 115, and the communication processing unit 105 (S101). The control unit 100 receives the write information 311 of the other terminal device 1 from the conference server device 3 (S102). The control unit 100 displays the shared screen 401 in the screen 400 based on the shared document 36 received in S101 (S103).

  The control unit 100 determines whether or not a memo image based on the writing information 311 of all the other terminal devices 1 has been displayed (S104). When it is determined that the memo image based on the writing information 311 of all the other terminal devices 1 is displayed (S104: YES), the control unit 100 displays the memo image created by the terminal device 1 (S105), The writing information 311 and the display / non-display information 415 are transmitted to the conference server apparatus 3 (S106). The conference server device 3 stores the write information 311 and the display / non-display information 415 transmitted from each terminal device 1 in the storage unit 32. These pieces of information are stored in storage areas provided for each terminal device 1.

  On the other hand, when it is determined that the memo image based on the writing information 311 of all the other terminal devices 1 is not displayed (S104: NO), the control unit 100 reads the writing information 311 of one other terminal device 1. (S107) It is determined whether or not the display / non-display selection button 405 corresponding to the one other terminal device is set to be displayed (display on / off) (S108).

  When it is determined that the display / non-display selection button 405 corresponding to the one other terminal device is set to display, that is, when the display is on (S108: YES), the control unit 100 proceeds to the process of S109. If not, that is, if the display is off (S108: NO), the process returns to S104.

  When it is determined in S108 that the display / non-display selection button 405 is set to display, the control unit 100 determines whether all objects have been processed based on the writing information of the one other terminal device ( If it is determined that all objects have been processed (S109: YES), the process returns to S104, and if it is not determined (S109: NO), the process proceeds to S110. The control unit 100 reads an unprocessed object (S110), creates and displays a memo image based on the object (S111), and returns to the process of S109.

  The processing of S108 and S111 will be described more specifically. As described above, the display / non-display selection button 405 for selecting whether or not to display a memo image written by another conference participant is arranged on the left side of the sharing screen 401. Here, when the conference participant operates the display / non-display selection button 405 corresponding to the terminal device 1 of at least one other conference participant in the own terminal device 1, the display setting is selected. When the display / non-display information 415 input by the participant indicates the display, the memo image of the other conference participant is displayed on the screen together with the shared document 36. On the other hand, when the display / non-display information 415 input by the conference participant indicates non-display, the memo images of other conference participants set to be hidden are not displayed on the screen.

  FIG. 8 is an explanatory diagram illustrating an example of a screen obtained as a result of processing by the terminal device 1 in the electronic conference system according to the first embodiment. In this example, a memo image based on the writing information 311 generated by the A terminal device 1 is drawn superimposed on the shared document 36.
