Description

  The present invention relates to a conference using an electronic computer, and in particular, it is possible for a participant himself / herself to distribute the distribution of materials after the conference to an arbitrary e-mail address according to each participant's notes and conference materials. Related to an electronic conference system.

In recent years, electronic conference systems using computer networks are becoming popular. As an advantage of electronic conferencing, in particular, the paperlessness of the conference can be raised by using an electronic file for the conference material. For example, the conference management system disclosed in Patent Document 1 stores conference materials used for a conference in a storage device of a server that allows access to a presentation terminal installed at a conference holding location through a network. memory is not stored address to store the conference list that stretched the hyperlink, depending on the installation presentation for the terminal to the terminal and the conference venue of the conference participants if you have access to the conference catalog, in a meeting anywhere at any time conference participants Necessary materials can be freely referred to, and presentations can be made without distributing paper-based conference materials at the conference venue.

  Further, in Patent Document 2, in consideration of the circumstances of attendees at the conference, the conference information (meeting name, location, etc.) regarding the conference held in the conference space after the conference ends, and the electronic blackboard printer Generates a composite minutes (composite information) by combining the minutes information output and read to each attendee, makes the contents different, and distributes the composite minutes from the information processing device to each attendee The invention to be distributed is disclosed. Synthetic minutes can be generated for each attendee so that each participant's needs can be met.

  In such a paperless conference system, the adverse effects caused by paper materials, such as waste of resources due to the consumption of large amounts of paper and waste of preparation time, obfuscation due to damage, information leakage due to loss or theft, etc. are improved. be able to.

  However, when a paperless meeting according to Patent Document 1 is held, the meeting material is an electronic medium, and participants cannot write notes on the material while listening to the meeting, unlike a paper medium. . In addition, in the case of materials that are prohibited to be taken out, there are problems such as automatically erasing them and leaving nothing at hand.

  In Patent Document 2, the minutes information is described on the electronic blackboard 2, and an electronic blackboard is required as hardware in order to save it as electronic data. In addition, the minutes information is not created by each participant, but is used exclusively by the moderator using the electronic blackboard. Therefore, the memos and the like written by each participant had to be written separately on the paper by the participant himself / herself, or created and stored electronically by himself / herself.

  Therefore, in the present invention, the memorandum of the conference material created by the participant during the conference that does not have banding restrictions can be sent to any e-mail address by the participant himself / herself at the end of the meeting, and has a banding restriction. The meeting materials prepared by the organizer can be distributed to participants after returning to the organizer once at the end of the meeting and then obtaining permission from the organizer (such as URL access restrictions). Provide a highly secure electronic conference document distribution system that can prevent information leakage by limiting.

In order to achieve the above object, an electronic conference system according to the present invention is an electronic conference system that performs a paperless conference, a plurality of terminals used by participants in the electronic conference system, storage of materials with restrictions on taking-out, and A management server that transmits the material to the plurality of terminals that are permitted to be connected, and the terminal can be used as a terminal for conference participation by registering with the management server The present invention can be used by switching between the presenter terminal granted the presenter authority by the selection of the presenter switching setting and the participant terminal not given the presenter authority. Means for adding memo data comprising the first memo, the second memo, and the third memo to the conference material, and the memo data input for each terminal is left in the conference material. Means for selecting whether or not, and the input means inputs a text sentence on a dedicated input screen for the third memo and stores the page number of the conference material in which the third memo is written When the management server chooses to leave the memo data, the management server selects the first memo and the first memo data that are the memo data for each terminal in the data that is restricted to be taken out. The two memos are synthesized in a form superimposed on the material, the third memo has means for inserting the page number and attaching it to the end of the material, and the management server the article with the take-out limit stored in the server is transferred to the terminal which permits the connection, characterized in that the article after the conference is intended to remove from the terminal.

In the electronic conferencing system of the present invention, the terminal has means for obtaining an e-mail address for notifying a place where the memo data is stored in the management server when it is selected to leave the memo data. To do.

According to the present invention , the conference material can be downloaded to the mobile terminal only when there is authentication from the mobile terminal registered in advance in the management server, and the conference material can be viewed during the conference. By not downloading to unclear terminals that are not pre-registered, the risk of information leakage is reduced. In addition, since the conference material is deleted from the portable terminal after the conference ends, a paperless conference that can further reduce the risk of information leakage from the portable terminal can be realized. In addition, since the conference material is stored centrally in the management server, it is easy to manage and is suitable for preventing unauthorized access from the outside and strengthening security.

  In addition, it is possible to create memo data (first and second memos) in which a memo is overwritten on the conference material displayed on the mobile terminal during the conference, and the conference material and the first 1. Composing the second memo to create a composite material, storing it in a predetermined storage location on the server, and sending an email describing the storage location to the email address of the conference participant, Later, the composite material can be downloaded from the storage location. Since it is possible to distribute meeting materials as electronic data, a paperless meeting can be realized.

  In addition, it is possible to switch between the conference material and the screen during a conference and create a memo (third memo) by a text sentence. As with the first and second memos, the conference material can be distributed as electronic data, so a paperless conference can be realized.

  In addition, since the first memo to the third memo are deleted from the portable terminal after the conference is finished, it is possible to reduce the risk of information leakage from the portable terminal.

In addition, since the conference material, the first memo to the third memo, and the composite material are deleted from the portable terminal and the management server after the conference is ended by the deletion instruction by the administrator or the determination of the elapse of the designated date, etc. The risk of spillage can be reduced.
In addition, since the composite material limits the period during which participants can download from the management server according to the download deadline specified when registering the conference, the problem that the composite material remains in the management server is solved. can do.
In addition, the composite material can be deleted by the participant himself / herself after downloading from the management server, and the convenience of the participant can be improved.

[First embodiment]
The conference system will be described below with reference to the drawings.
[System Overview]
FIG. 1 is a diagram showing an overview of the entire system of the present invention. The conference system 1 includes a management server 3, a presentation terminal 5, a wireless router 7, and a network 2. In addition, the mobile terminal 10 is prepared in a state where it can be connected to the network 2.

  The network 2 may use the Internet, but can also be used as an in-house LAN (Local Area Network) or a stand-alone network independent from the outside. This is because an independent network has high confidentiality and can prevent intrusion from outside or leakage or destruction of information.

  The management server 3 controls the operation of the conference system 1, stores conference material 20, registers / deletes participant information, manages individual setting information of the mobile terminal 10, etc., and stores these various types of information 30 (see FIG. 2).

  The presentation terminal 5 is a terminal used by the presenter during the conference. It has functions such as the start and end of the conference, the control of the conference material 20 during the conference, and the instruction to delete the material in the portable terminal 10.

  The wireless router 7 has a function of communication connection between the network 2 and the mobile terminal 10. The communication method may be a wireless connection such as Bluetooth (registered trademark), Wi-Fi (wireless fidelity: registered trademark), IrDA (Infrared Data Association), or a wired connection using a coaxial, optical cable, or the like using Ethernet (registered trademark). It is sufficient that the network 2 and the mobile terminal 10 have a configuration capable of transmitting and receiving data between each other.

  The mobile terminal 10 is a terminal used by conference participants. It has a function of browsing the conference material 20 and creating a memo during the conference.

[Management Server]
The management server 3 has a built-in or external storage area, and an application for the management server 3 is installed in the storage area to control the entire conference system 1. In addition, a database 30 relating to the conference system 1 is constructed in the storage area (see FIG. 2).

An application for the management server 3 is activated in the management server 3, and commands are transmitted to and received from the application for the presentation terminal 5 and the application for the mobile terminal 10. The management server 3 for applications to send and receive commands to multiple application for presentation terminal 5 and the mobile terminal 10 for application during startup, resides on the management server 3, it is preferred event-driven. Event-driven is a program execution format that performs processing in response to an event (operation) executed by a user or another program. When the user is not performing an operation, the program waits for execution of the operation. Therefore, the user can operate other programs while waiting for the program. This is an execution method widely adopted in programs having a GUI (Graphical User Interface) user interface.

  As shown in FIG. 2, the database 30 includes information on the conference system 1 as conference information 31, conference material information 32, participant information 33, portable terminal information 36, memo information 34, memo material download deadline 31f, memo. Each table includes information additional meeting material information 35, portable terminal information 36, and the like. Input / output and access to the database 30 are executed by the management server 3 application.

  The management server 3 manages the mobile terminal 10. By performing setting registration / deletion or the like in the portable terminal information 36 of the database 30, it is managed whether or not the portable terminal 10 can be used in the conference system 1. As shown in FIG. 3A, on the new conference information creation screen (basic information) 31A, the conference name 31a, the date 31b, the date 31c, the content 31d, the contents 31d, the expiry date 31e, and the memo material It has a function to register and change the download deadline 31f and the like.

  FIG. 3B displays a material list 31g of the conference material 20 used for the conference on the new conference information creation screen (material) 31B. The management server receives the conference material 20 used in the conference from the presenter and the participant and stores it in a predetermined location in the storage area. The administrator converts the received conference material 20 into a file format that can be browsed by this system, and stores it again in a predetermined location in the storage area of the management server. In the present invention, the converted file format is a PDF (Portable Document Format: registered trademark) format. Further, FIG. 3B has buttons for material addition 31h, replacement 31i, deletion 31j, and preview 31k for operating the material information.

  FIG. 3C shows the participant / presenter information for the conference on the new conference information creation screen (participant) 31C, and operations for deleting the participant information 33 31l, adding 31m, and registering 31n. Has a button.

  In addition, the management server 3 acquires the memo information data 41 created by each participant during the conference from each portable terminal 10 at the end of the conference and stores it in a storage location in the management server 3. The memo information data 41 can be confirmed with a memo material list shown in FIG. Then, by the function of the management server 3, a memo information added conference material 42 in which the memo information 34 and the conference material 20 are synthesized and created is created and stored in the database 30. Then, the management server 3 acquires the email address of the participant who created the memo information data 41 from the participant information 33, or the participant himself / herself inputs the email address directly when sending the email, and sends the email to the participant. The storage location of the memo information additional meeting material 42 is described and transmitted to the participants. Each participant accesses the storage location described in the e-mail and downloads the memo information-added meeting material 42.

  As described above, it is possible to create a conference material as if the participant directly wrote in the conference material 20 and distribute it to the participants.

Processing such as transmission / reception of commands to / from the management server 3, the presentation terminal 5 and the portable terminal 10 and access to the database 30 is actually performed by operating the management server 3 application. skip "application" in to as operating the "management server 3 '.

[Presentation terminal]
The presentation terminal 5 is a terminal that is operated by a presenter in a conference. A command for operating the conference material 20 displayed on the mobile terminal 10 by operating an application on the presentation terminal 5, a command for deleting the conference material 20 stored in the mobile terminal 10, etc. 3 to send. The presentation terminal 5 can be used by changing the setting of the mobile terminal 10.

  As shown in FIG. 4A, the mobile terminal 10 used by the presenter displays the mobile terminal setting screen 37, selects “ON” in the “presenter” switching setting 38, and presenter authority Can be used as the presentation terminal 5. The presenter can be a person who has previously registered “presenter” in the conference participant information 33.

  Alternatively, when a participant wishes to make a presentation during a conference, the presenter gives permission, and the participant's mobile terminal 10 is used as a presentation terminal 5 ′ that has been given the authority of a temporary presenter. I can do it.

The procedure for granting authority for the temporary presenter is shown below. When a notification to the effect that the presenter's authority is desired is sent from the mobile terminal 10 of the participant who wishes to present to the presenting terminal 5 having authority, the presenter application screen 39 is displayed on the presenting terminal 5 ( (See FIG. 4B). Next, when the presenter presses “permit” on the presenter application screen 39, a notification is given to the portable terminal 10 of the participant who wants to present the temporary presenter, and the presenter terminal 5 Can be used as'. In this case, the announcement terminal 5 ′ may be limited in the functions used in comparison with the announcement terminal 5. Further, the presenter and the presentation terminal 5 can forcibly restrict and release the temporary presenter authority of the presentation terminal 5 ′.

  Further, although the presentation terminal 5 has the same application as that of the portable terminal 10, access authority and operation to the management server 3 differ depending on the presenter authority. When browsing the contents of the database 30 such as browsing the conference information 31 on the presentation terminal 5, the presenter operates the application, and the application for the presentation terminal 5 directly accesses the database 30 and information. And the extracted information is displayed on the screen of the presentation terminal 5, so that the presenter of the presentation terminal 5 can browse the information in the database 30.

  In addition, processing such as transmission / reception of commands to / from the presentation terminal 5, the management server 3, and the portable terminal 10 is actually performed by operating an application. However, in the following description, “application” is omitted, and “announcement” Terminal 5 ”is described as operation.

[Mobile devices for participants]
A mobile terminal 10 shown in FIG. 5 is a device for a conference participant to browse the conference material 20 during the conference and to input a memo related to the conference material 20. The mobile terminal 10 has a storage device inside or outside, and an environment in which an application for the mobile terminal 10 is installed in the storage area or an online program created in a script language or the like can be executed. have. In addition, the conference material 20 transferred from the management server is stored, and the conference participant displays the conference material 20 on the screen of the portable terminal 10 during the conference.

  In addition, the participant has an input device that can be operated, and the participant can write a memo so as to be overwritten on the conference material 20. In order to select / display a memo function, which will be described later, A memo input selection button 21 (21a to 21d) is provided. The created memo is stored in the storage area. The conference material 20 can display an arbitrary page by a participant during the conference. In addition, when the participant presses a “synchronization” button (not shown), the same page as the page displayed on the presentation terminal 5 can be opened.

At the end of the conference, after the memo is transferred to the management server 3 and the command from the presentation terminal 5 by the presenter or the browsing deadline 31e has elapsed, the mobile terminal 10 stores the next conference material information 32. When displayed, the conference material 20 stored in the mobile terminal 10 is deleted.

In addition to lending a portable terminal device at the start of the conference, the conference participant may use the portable terminal device owned by the participant by registering in the management server 3 .

  The portable terminal 10 can be a desktop personal computer, a notebook personal computer, a PDA (Personal Digital Assistant) as long as an application dedicated to the portable terminal 10 or an online program created in a script language can be operated and the conference material 20 can be viewed. Regardless of the device, the OS (Operation System) is also used for personal computers such as MS-Windows (registered trademark) and Mac OS (registered trademark), iOS (registered trademark) for mobile terminals, and Android (registered trademark). (Trademark), etc. may be used. The input device may be any device such as a mouse, a tablet, or a touch panel that can be operated by a user and input to the terminal. In the present embodiment, a portable terminal having a small and portable touch panel input format will be described as an example.

  Note that processing such as transmission / reception of commands between the mobile terminal 10 and the management server 3 and the presentation terminal 5 is actually performed by operating an application for the mobile terminal 10. Omitted, and “mobile terminal 10” is described as operation.

[Memo creation function]
Next, the memo function of the present invention will be described with reference to FIGS. Since the conference material 20 viewed by the participant during the conference is electronic data, the present invention has a memo function so that the participant can mark the material or make a memorandum. Improves sex. There are three types of memos created by the memo function: a first memo, a second memo, and a third memo.

  6 is a diagram illustrating input of a first memo (handwritten memo) and a second memo (sticky note), FIG. 7 is a diagram illustrating input of a third memo (text memo), and FIG. 8 is a diagram illustrating a memo list screen. FIG. 9 is a diagram showing a screen for displaying the state after the memo composition.

  As shown in FIG. 6, the participant starts the memo input during the conference, so that the memo input selection button 21 (“handwritten memo” mode button 21a, “text memo” mode button 21b) of the portable terminal 10 is used. By pressing, the memo function can be used for the conference material 20 displayed on the screen.

  The first memo is a function of “handwritten memo”. For example, like the handwritten memo 23, the first memo is superimposed on the conference material 20 being displayed on the mobile terminal 10 and placed at an arbitrary position on the screen. You can write in any size and color. By pressing the “handwritten memo” mode button 21a, the state changes to a state where a memo can be input. Since a touch panel is used in this embodiment, handwriting input can be performed with a finger, a stylus pen, or the like. Moreover, you may input with a mouse | mouth etc. as an input device.

  The second memo is a function of a so-called “sticky note”, and a character or the like is input to a range of a small piece of graphic (for example, a sticky note 24) and is superimposed on the conference material 20 being displayed on the mobile terminal 10, An object to be placed at an arbitrary position on the screen. By pressing the “sticky note” mode button 21d, the state transitions to a state in which the sticky note 24 can be input. As with the first memo, handwriting input with a finger, stylus pen, etc., or input with a mouse, keyboard, etc. may be used. The sticky note part can be placed on a conference material 20 being displayed on the mobile terminal 10 and placed at an arbitrary position, and the placement position can be easily moved with a mouse, keyboard, etc., and placed at a new position. is there. Moreover, it is not necessary to input characters or the like in the tag part, and it is also possible to give a tag as a mere mark.

  The third memo is a function of “text memo”, and when the “text memo” mode button 21b is pressed, the screen shifts to a dedicated text memo input screen 25 (see FIG. 7). In the text memo input screen, characters are input on the screen by a pseudo keyboard 26 by software or a keyboard as an input device. Alternatively, software that inputs characters with a finger, a stylus pen, etc., automatically converts characters, and inputs characters on a text memo input screen may be installed.

  As for the input information of the first memo and the second memo, the page, position, size, etc. of the conference material 20 on which the memo is written are recorded in the memo information data 41 and stored in the storage area of the portable terminal 10. Is done. Once the memo information data 41 once created, even if the page of the conference material 20 is turned, when the page number is displayed again, as shown in FIG. 6, the conference material 20 and the handwritten memo 23 and the tag 24 are displayed in an overlapping manner. It appears as if it were written on actual paper material.

  The information of the inputted third memo is edited by automatically inserting the page number of the conference material 20 on which the memo is written into the third memo and editing it as text memo information data (not shown). It is recorded in the information data 41 and stored in the storage area of the mobile terminal 10.

[Memo display function]
Further, the present invention has a display function of the memo information data 41. During the conference, the participant presses the “memo list” screen button 21 c while displaying the conference material 20 to display the memo list screen 27 as shown in FIG. 8 and stored in the memo information data 41. The contents of the first memo to the third memo can be displayed as a thumbnail 44 for confirmation. When the “all” button 28a is pressed on the memo list screen 27, all memos from the first memo to the third memo are displayed. When the “handbook” button 28b is pressed, a screen showing a list of contents of the first memo is displayed. When the “sticky note” button 28c is pressed, a screen showing a list of contents of the second memo is displayed. When the “text” button 28d is pressed, a screen showing a list of contents of only the third memo is displayed. In this way, it is possible to display the contents of the memo data corresponding to each button extracted from the memo data.

  For example, as shown in FIG. 8, when the “all” button 28 a is clicked, the first thumbnail 44 a and the second thumbnail 44 b are displayed on the memo list screen 27. The first thumbnail 44a is displayed so that the page number, the first memo (handwriting), and the second memo (sticky note) are present. The second thumbnail 44b is displayed with an icon indicating that a third memo (text memo) exists. The first thumbnail 44a and the second thumbnail 44b can be enlarged and displayed by double-clicking or tapping each.

[Meeting materials and memo information data materials]
When the “Save” button (see FIG. 11) of the memo is pressed at the end of the conference, the conference material 20 and the memo information data 41 (the first memo, the second memo, and the third memo) are combined into one, A new memo information addition meeting material 42 is generated. At this time, as shown in FIG. 9, the first memo and the second memo are the positions where the memos of the conference material 20 were made (handwritten memo information additional conference material 42a), and the third memo is the memo information additional conference material 42. Edited together at the end (text memo information addition meeting material 42b) and attached.

[System operation]
Hereinafter, the operation of the conference system 1 will be described with reference to FIGS. 12 to 15. 12 and 13 show preparations for the conference such as setting of each device and information registration in the database 30 when the conference is held, and FIGS. 14 and 15 show processing from the start to the end of the conference.

[System Initial Registration]
First, FIGS. 12 and 14 will be described. Applications are installed in the management server 3 and the mobile terminal 10 (presentation terminal 5), respectively (step S1). When the application for presentation terminal 5 and the application for portable terminal 10 are activated for the first time, the administrator needs to set each terminal to be registered in the conference system. The administrator is a person who performs management and maintenance related to the conference system 1.

  When the mobile terminal 10 is installed for the first time after the application for the mobile terminal 10 is installed in the mobile terminal 10, a screen for setting the connection to the management server 3 (not shown) is displayed on the screen of the mobile terminal 10, and a confirmation (OK) button is displayed. By pressing, the management server 3 is requested for authentication. At this time, information of the portable terminal 10 is registered in the management server 3 (step S2). The terminal information registration items are a terminal ID, an identifier (administrative name), and the like. The terminal ID is, for example, a Mac address (Media Access Control address), a UDID (Unique Device Identifier), an Android ID, or the like. It may be a unique identification number that can be identified by the mobile terminal 10.

  Next, the administrator selects a terminal from a list of registered mobile terminals (not shown) and presses an approval button to permit connection of the terminal. Authentication is rejected for portable terminals that are not approved by the management server 3 (step S3). As described above, since only registered terminals can log in to the conference system 1, access from unapproved and unknown portable terminals 10 can be restricted, and security is enhanced.

[Conference data registration: Conference information registration]
Next, the conference information is registered. When a new conference is held, the administrator displays a new conference information creation screen (basic information) 31A shown in FIG. 3A on the management server 3 and registers various conference information (step S4). The contents of registration include a meeting name 31a, a date and time 31b, a holding location 31c, a content 31d, a browsing deadline 31e, a memo material download deadline (memo information deletion deadline) 31f, and the like.

[Conference data registration: Registration of meeting materials]
When the registration of the conference information 31 is completed, the conference material 20 is stored in the storage area in the management server and is associated with the conference information 31 (step S5). The conference material 20 is delivered from the presenter to the manager. The delivery means may be any means as long as security problems do not occur, such as those stored in a medium, attached to an e-mail, or via a network such as an in-house LAN. The administrator presses the material addition button 31h on the conference information new creation screen (material) 31B shown in FIG. 3B and designates the delivered conference material 20 to register the information in the database 30. (Step S5). When the information is registered, the file name, presentation material name, conversion result, etc. are displayed in the conference material column 31g of the screen. One or more meeting materials 20 may be used in one meeting. In the case of a plurality, the step S5 is repeated for the number of meeting materials.

[Conference data registration: File format conversion of meeting materials]
Next, when the file format of the registered conference material is different from the file format specified by the conference system, a process of converting to the file format specified by the conference system is performed (step S6). This is because, when each material is delivered in a different file format, unification makes it easy to operate the entire system. Since the file name of the registered conference material is displayed in the conference material column 31g shown in FIG. 3B, the file format can be determined from the extension. In this embodiment, the conference material is converted into a PDF format file. By specifying the conference material 20 to be converted and executing the PDF conversion process, the file format of the conference material 20 in the storage area is converted to PDF, and the file name registered in the database 30 is converted to the converted file name. The meeting material column 31g is updated and displayed with the file name after conversion and the conversion result. File conversion may be performed for each file or for a plurality of files at once.

[Meeting data registration: browsing deadline registration]
Next, the browsing deadline 31e for the conference material 20 is input (step S7). The browsing deadline sets a final date and time when the conference material 20 can be browsed on the mobile terminal 10. The mobile terminal 10 confirms the browsing deadline 31e of the conference material 20 stored in the mobile terminal 10 at the time of activation, and deletes the conference material 20 when the browsing deadline 31e has elapsed. It is preferable to set it after the scheduled end time (year / month / day / hour / minute) of the conference.

Next, the download deadline (memo information deletion deadline) 31f of the conference material 20 (memo information addition conference material 42) is set (step S8). Each participant accesses the storage location described in the e-mail sent after the conference and downloads the memo information-added conference material 42. However, it is preferable to limit the time limit for security and resource management. Absent. Therefore, a memo material download deadline (memo information deletion deadline) 31f is input to determine a download deadline after the conference ends . And the memo information addition meeting material 42 which passed the download time limit (memo information deletion time limit) 31f is completely deleted.

[Conference data registration: Participant registration]
Next, the information on the participants of the conference is registered in the participant information 33 of the database 30 (step S9). The administrator inputs the participant data of the conference from the registration screen (not shown) of the participant in the management server 3 and registers it as participant information 33. The data to be registered includes name, title, affiliation, e-mail address, ID, password, presenter authority, and the like. Here, the ID and password are used for authentication of login to the conference system, and do not limit the participants for each conference. When a participant is registered, it is recorded in the database 30 and displayed in a list (not shown) on the participant management screen. The registered participant data is valid until the administrator deletes it, and can be used for multiple meetings.

[Preparation for meeting: Select meeting information]
First, the conference to be held is selected (activated) from the conference management screen (not shown) of the management server 3 (step S10). By selecting a meeting, the meeting becomes an object to be held. In the present invention, it is possible to download the conference material 20 from the management server 3 to the mobile terminal 10 by setting it as an object to be held. This is to prevent accidental downloading of materials from other meetings.

[Preparation for meeting: Connection of mobile terminal]
Next, the mobile terminal 10 is activated and a conference selection screen (not shown) is displayed. On the conference selection screen, the URL of the conference distributed in advance to the application is input. Then, the mobile terminal 10 transmits a connection permission request to the management server 3. The portable terminal 10 communicates with the wireless router 7 via a wireless LAN, and sends a request to the management server 3 via the network 2. Since the management server 3 is an event-driven system, it continues to wait for commands from the mobile terminal 10 and the presentation terminal 5. The management server 3 returns a response to the command.

  When the terminal ID of the mobile terminal 10 that has requested authentication is registered in the database 30, the management server 3 sends back a response indicating successful authentication to connect the mobile terminal 10 (step S <b> 11).

[Preparation for meeting: download]
When the connection due to the successful authentication between the mobile terminal 10 and the management server 3 is established, the management server 3 transmits the conference information 31 selected in step S10 and the conference material 20 of the conference to the mobile terminal 10 (step S12). ). The mobile terminal 10 stores the conference material 20 in the storage area. When a plurality of conference materials 20 are described in the conference information 31, the process ends when the mobile terminal 10 determines that all of the plurality of conference materials 20 have been downloaded to the mobile terminal 10. To do.

[Start Meeting]
Next, processing of the conference system 1 relating to the start of the conference, during the conference, and the conference end will be described with reference to FIGS. 13 and 15. The conference may be an environment that can be connected to the network 2 even in a remote place such as a conference room where the network 2 is constructed, or a corporate head office and branch office.

[Conference start: Setting of presentation terminal 5]
Here, the conference is started when the presenter's mobile terminal 10 can be used as the presentation terminal 5 by setting the “presenter” switching setting 38 to “ON” as described above. (Step S21). At this point, the mobile terminal 10 accessing the conference URL starts participating in the conference.

[Conference start: Activation of mobile terminal 10]
Participants of the conference should either lend the mobile terminal 10 used in the conference at the conference venue or bring their own mobile terminal 10 registered in the mobile terminal information 36 to the conference venue for use. Can do. When the participant turns on the power of the mobile terminal 10 at the meeting venue (step S22), the mobile terminal 10 is activated, performs authentication communication with the management server 3, and the mobile terminal 10 stores the mobile terminal information 36. If registered, it is determined that authentication is normal, and a “participant authentication screen” (not shown) is displayed. If the mobile terminal 10 is not registered in the mobile terminal information 36, the administrator can use the mobile terminal 10 by registering the mobile terminal 10 in the management server 3.

  Next, on the “participant authentication screen” (not shown), the ID and password of the participant who uses the portable terminal 10 are input and collated with information registered in the participant information 33 of the database 30 (step) S23). If it is determined by verification that the ID and password are correct, the participant is authenticated and can log in to the management server 3. Log in to the management server 3 to display a conference selection screen (not shown). On the conference selection screen, the URL of the conference distributed in advance to the application is input. When the mobile terminal 10 accesses the conference URL and the presenter's presentation terminal 5 starts using the conference terminal, participation in the conference starts (step S24).

[In meeting: Instructions to turn pages of meeting materials]
When the conference is started, the presenter turns the page of the conference material 20 displayed on the presentation terminal 5 by operating the input device in accordance with the progress of the conference (step S25). The operation method at this time is referred to as an “automatic operation” mode (see FIG. 17). When the page turning is performed, the presentation terminal 5 transmits a “page turning” command to the management server 3. The management server 3 receives the command and transfers the “page turning” command to the mobile terminal 10. When the mobile terminal 10 receives the command, the page of the conference material 20 is displayed so that the page described in the command is displayed, and the presentation material 5 and the conference material 20 of the mobile terminal 10 are synchronized and the same. The page will be displayed (hereinafter referred to as “synchronize”).

  During the conference, the participant can switch the operation method to “manual operation”, so that the conference material 20 displayed on the mobile terminal 10 can transition to an arbitrary page of the participant. Here, on the pages other than those where the presenter gave a lecture at the conference, a restriction that cannot be changed may be provided. When a “page turning” command is received from the presentation terminal 5 during “manual operation”, if an arbitrary page is displayed, the command does not need to be ignored and synchronized. When there are a plurality of conference materials 20, other materials can be browsed.

  The portable terminal 10 is provided with a “synchronization” button (not shown), and the conference material 20 of the presentation terminal 5 and the display page can be synchronized by pressing the button. At this time, the operation method is switched to “automatic operation”. Further, a button such as “forced synchronization” may be provided on the presentation terminal 5 and the pages of all the mobile terminals 10 may be forcibly synchronized by pressing the button.

[During meeting: Creation of memo information data]
As described above, during the conference, the participant, as shown in FIGS. 6 and 7, the memo input selection button 21 (“handwritten memo” mode button 21 a, “text memo” mode button 21 b of the mobile terminal 10. ) Can be used to use the memo function for the conference material 20 displayed on the screen (step S26).

  The first memo (handwritten memo) and the second memo (sticky note) are created as a memo information data 41 in a file different from the conference material 20, and are superimposed on the conference material 20, so that an arbitrary position on the screen is obtained. In addition, it can be written in any size and color. Since a touch panel is used in this embodiment, handwriting input can be performed with a finger, a stylus pen, or the like. Further, input may be performed with a mouse, a keyboard, or the like as an input device. The third memo (text memo) transitions to a dedicated text memo input screen 25 when the “text memo” mode button 21b is pressed (see FIG. 7). On the text memo input screen 25, characters are input on the screen by a pseudo keyboard 26 by software or a keyboard as an input device. Alternatively, software that inputs characters with a finger, a stylus pen, etc., automatically converts characters, and inputs characters on a text memo input screen may be installed.

  In addition, when the participant presses the “memo list” screen button 21 c of the mobile terminal 10, the memo list screen 27 is displayed as shown in FIG. 8, and the first memo stored in the memo information data 41 is displayed. The contents of the third memo are displayed as thumbnails 44 or enlarged, so that the contents of the memo inputted by the participant can be confirmed.

[End Conference]
The conference end process will be described with reference to FIGS. 13 and 16. When the conference ends, the management server 3 determines that the conference is ended when the participants terminate the application of their mobile terminals 10 and all the participants and the presenters leave the conference venue (step). S27). At this time, even if some of the participants and presenters leave the conference venue first, it does not affect other participants and presenters in the conference.

  When the participant's mobile terminal 10 terminates the application, the participant's mobile terminal 10 confirms the presence or absence of the memo information data 41. If the memo information data 41 exists, as shown in FIG. 29 is displayed (step S28). When the participant desires to leave the memo data input by himself / herself, he / she inputs an e-mail address for receiving an e-mail notifying the storage location of the conference material 20 and the memo data (memo information-added conference material 42). Alternatively, instead of input, an e-mail address may be automatically acquired from the participant information 33 and displayed in the dialog 29.

[Combination / transmission processing of memo information data]
Next, the management server 3 receives the memo information data 41 (step S29) , stores it in the storage area, and updates the information of the memo information 34 in the database 30. The memo information 34 is registered in the database 30 as the memo information 34 based on the name, title, affiliation, e-mail address of the participant information 33, and the conference name 31a and the conference material 31g of the conference information 31. The In this way, information is stored so that the creator of the memo information data 41 and the meeting name can be identified.

  On the other hand, when the participant does not save the memo data (No in step S28), the memo information data 41 is discarded and the conference is ended.

  Next, the management server 3 combines the memo information data 41 and the conference material 20 to create a memo information-added conference material 42 (step S30). The memo information data 41 and the conference material 20 are separate files, but they are superimposed and combined to form a single electronic file, as if the memo information was entered on the screen, directly participating in the conference material 20 Created as if written by the author. As shown in FIG. 9, during the composition work, the first memo and the second memo are at the position where the memo of the conference material 20 was made (handwritten memo information additional conference material 42a), and the third memo is the memo information additional conference. Edited together with the end of the material 42 (text memo information additional meeting material 42b) and attached. Note that the memo information addition meeting material 42 is preferably a file format that cannot be changed such as PDF, and may be subjected to measures such as digital watermarking to detect unauthorized copying or data tampering. The material synthesized in this way and synthesized as an electronic file is stored in the storage area (download site) of the management server 3 as the memo information addition conference material 42 (step S31).

  Next, the URL (Uniform Resource Locator) of the download site is transmitted to the mail address designated by the participant in step S28 (step S32). The participant can obtain the memo information-added conference material 42 obtained by synthesizing his memo with the conference material 20 by accessing the URL notified by e-mail and downloading the memo information-added conference material 42. In addition, the participant can delete the memo information addition conference material 42 from the download site after downloading the memo information addition conference material 42.

  When the transmission of the e-mail notifying the URL of the download site is completed, a message to that effect is transmitted to the mobile terminal 10 and the conference is terminated.

[Delete meeting materials]
Next, the presenter deletes the conference material 20 and the memo information data 41 stored in the mobile terminal 10 by pressing the “delete material” button on the presentation terminal 5 (step S33). This is to prevent information leakage by deleting various materials in the portable terminal 10. The memo information data 41 can also be deleted by the administrator.

  When the “deletion of material” is performed, the presentation terminal 5 transmits a “deletion of material” command to the management server 3. The management server 3 receives the command and transmits a “delete material” command to the mobile terminal 10. When receiving the command, the portable terminal 10 deletes all the conference material 20 and the memo information data 41 from the storage area. If the mobile terminal 10 fails to receive a “deletion of material” command such as when the power is off or the connection is released from the network 2, the next meeting material information 32 is obtained from the management server 3 and the mobile terminal 10. At the time of display, it is deleted from the storage area of the mobile terminal 10. If the power is turned off at the corresponding time, the conference material 20 is deleted when the first conference material list is displayed after the next power-on of the mobile terminal 10.

  Further, for the conference material 20 stored in the management server 3, the administrator operates the “conference information / registration screen” shown in FIG. 3, selects the material from the conference material column 31g, and presses the material deletion 31j. Thus, the conference material 20 is manually deleted from the conference information 31. When the conference material 20 of the management server 3 is deleted at the set date and time of the viewing deadline 31e, an instruction for investigating whether the conference material 20 remains in the mobile terminal 10 is transmitted from the management server 3 to the mobile terminal 10, and the conference material If 20 remains, the conference material 20 of the mobile terminal 10 is deleted.

  In this way, participants in the conference do not use paper-based materials during and after the conference, and can manage memos during the conference as electronic data in an integrated manner. Further, since the participant can use the portable terminal 10 without taking in and deleting the conference material 20 in the portable terminal 10 before and after the conference, the burden on the participant is reduced.

[Second Embodiment]
The conference system according to the present invention stores the above-mentioned memo information-added conference material 42 in the storage area (download site) of the management server 3 (step S31), and sets the URL of the download site to the e-mail address designated by the participant. Instead of the method in which the participant downloads and obtains the memo information addition meeting material 42 from the URL, the memo information addition meeting material 42 is downloaded and obtained from the URL by transmitting by e-mail (step S32), the memo information addition meeting It is also possible to send the document 42 attached to the participant and obtain it.

The processing of the second embodiment is shown below.
The management server 3 combines the memo information data 41 and the conference material 20 to create a memo information-added conference material 42.

Next, the management server transmits the memo information addition conference material 42 to the mobile terminal 10, and the mobile terminal 10 temporarily stores the transmitted memo information addition conference material 42.
Next, the participant transmits the memo information-added meeting material 42 attached to the email address designated by the participant in step S28 as an e-mail. After the e-mail is transmitted, the memo information-added meeting material 42 is automatically or manually deleted (step S33) .

  By doing in this way, the participant can obtain the memo information-added conference material 42 in which his memo is synthesized with the conference material 20 after the conference is completed. In this embodiment, the download site is not necessary, and the load on the management server 3 is reduced. In addition, the participant does not need to download at a later date, and convenience is improved.

[Other Examples]
The conference system according to the present invention may implement the following functions in addition to the above embodiment.

[Video material]
As another example of the present conference system, the conference material 20 may use not only text and PDF data but also moving image / audio material. The moving image file format may be any format such as QuickTime (registered trademark) or MPEG (Moving Picture Experts Group) as long as it can be played back by the presentation terminal 5 and the mobile terminal 10.

[Questionnaire voting function]
For example, since the mobile terminal 10 and the management server 3 can transmit to each other, a questionnaire voting function may be implemented in the mobile terminal 10. A function may be provided that allows the management server 3 or the announcement terminal 5 to aggregate immediately after voting and the results can be aggregated.

[Meeting document viewing restriction function]
For example, it is possible to provide a function for limiting the data that can be downloaded from the management server 3 to the mobile terminal 10 in accordance with the authority of the employee's job title, department, paid participant in the conference, or free participant. Only necessary materials can be provided for each participant.

[Offline use]
Further, even when the portable terminal 10 is in an offline state where the portable server 10 is not connected to the management server 3, it is possible to refer to the material downloaded to the portable terminal 10. In that case, security is ensured by performing ID and password authentication for offline status.

  As described above, according to the electronic conferencing system of the present invention, the conference material is downloaded to the mobile terminal only when there is authentication from the mobile terminal registered in advance in the management server. Can be browsed during the meeting, the risk of information leakage is reduced by not downloading to unclear terminals that are not pre-registered. In addition, since the conference material is deleted from the portable terminal after the conference ends, a paperless conference that can further reduce the risk of information leakage from the portable terminal can be realized. Moreover, since the conference material is stored centrally in the management server, it is easy to manage, and is suitable for preventing access from the outside and strengthening security.

  In addition, it is possible to create memo data (first and second memos) in which a memo is overwritten on the conference material displayed on the mobile terminal during the conference, and the conference material and the first 1. Combining the second and second memos to create a composite document, storing it in a predetermined location on the server, and sending an e-mail describing the storage location of the server to the email address of the conference participant. Can download the composite material from the storage location at a later date. Since it is possible to distribute meeting materials as electronic data, a paperless meeting can be realized.

  In addition, it is possible to switch between the conference material and the screen during a conference and create a memo (third memo) by a text sentence. As with the first and second memos, the conference material can be distributed as electronic data, so a paperless conference can be realized.

  In addition, since the first memo to the third memo are deleted from the portable terminal after the conference is finished, it is possible to reduce the risk of information leakage from the portable terminal.

  In addition, since the conference material, the first memo and the third memo are deleted from the portable terminal and the management server after the conference is ended by a deletion instruction by an administrator or determination of the elapse of a specified date, there is a risk of information leakage, etc. Can be reduced.

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
