Description

  The present invention relates to an information sharing technique, and more particularly to an information processing system, an information processing apparatus, and a program for improving information sharing efficiency by presentation.

  In recent years, an information processing apparatus referred to as a so-called electronic information board in which a touch panel is mounted on a large display using a flat panel or a projector such as liquid crystal or plasma has been known. A known electronic information board connects a personal computer (hereinafter simply referred to as a user PC) to the electronic information board via a VBA interface, a USB interface, or the like. Since the electronic information board enlarges and displays the screen information displayed by the user PC connected via the interface, it is preferably used for presentations and education at meetings in organizations such as companies, government agencies, and educational institutions. Can do.

  In recent electronic information boards, since the liquid crystal display device has a touch panel function, the information displayed on the electronic information board is not directly operated by the mouse from the user PC, but directly touched on the touch panel. It is possible to use a pen-type external input device. Conversely, this function also provides a function of interactively controlling the user PC from the electronic information board.

  The operation of the electronic information board is controlled by electronic blackboard software that operates on the user PC. In addition to providing a screen that acts as a blackboard, the electronic blackboard software has a function for drawing handwritten characters and the like on the touch panel, a function for taking a screen displayed by the user PC and superimposing handwriting on the screen, etc. Is provided.

  Using an electronic information board with such a handwriting function, you can write additional items directly on the screen as needed while manipulating display materials for explanation at office meetings, etc. The screen content including it can be recorded. As a result, the user can look back on the screen contents at the end of the conference, and can expect to efficiently conclude conclusions and the like by reusing the screen contents.

  In a conference using an electronic information board having such functions, it is possible to operate the electronic information board without disturbing the progress of the conference, and to display and input information in a timely manner, so that the presentation can be smoothly advanced. Preferred to do.

  However, with conventional electronic information boards, when conference materials created by another information processing device such as PowerPoint (registered trademark) or PDF are displayed on the electronic information board, the conference materials are once read into the user PC, The meeting materials needed to be displayed on the electronic information board. At this time, when the conference material is spread over multiple pages, to display all the conference materials on the electronic information board, the page of the conference material is switched by the operation of the user PC. I had to repeat the operation of acquiring the image of the material. This requires the user to control both the electronic information board and the user PC, causing a problem of lack of smooth display properties.

  In order to improve this problem, a method using electronic mail has been proposed. For example, Japanese Patent Laying-Open No. 2005-100223 (Patent Document 1) has an object to provide a remote processing device that increases the security against unauthorized remote operation while ensuring the convenience of issuing an instruction for remote operation by e-mail. As described above, the user transmits a remote operation e-mail described with the encryption information set for himself / herself, and the remote device describes the remote operation instruction from the user with the encryption information associated with the user. A method is disclosed in which a received electronic mail is received and decrypted, and processing is performed according to the decrypted instruction content.

  As described in Patent Document 1, when the conference material is sent to the electronic information board using electronic mail, there is an advantage that a PC is not required when the conference material is taken into the electronic information board. However, even if there are multiple pages of meeting material in this case, the page to be imported when the meeting material is imported to the electronic information board cannot be specified, so unnecessary pages in the meeting material are imported and the stability of the display is impaired. There is a problem that the display speed decreases.

  Japanese Patent Laid-Open No. 2006-338211 (Patent Document 2) requests that an electronic file be acquired when a request input unit receives a print request for an electronic file stored in a document management server. A technique is described in which an electronic file is requested from a document management server and a file receiving unit receives the electronic file, and prints and displays the electronic file.

  Although Patent Document 2 describes that an electronic file is acquired and printed / displayed, a page to be imported when the conference material is imported to the electronic information board cannot be specified, so even unnecessary pages in the conference material are imported. Therefore, it does not solve the problem that the stability of display is impaired or the display speed is lowered.

  In the present invention, when a conference material over a plurality of pages is taken into the electronic information board using the network, the page that the user wants to take in the electronic information board is written in the header or body of the mail. The electronic information board captures only the page of the conference material specified by the page information that specifies the page to be extracted from the attached conference material. Thereby, it is possible to prevent the conference information unnecessary for the conference from being taken into the electronic information board. As described above, an object of the present invention is to simplify use when a user uses an electronic information board.

According to the present invention,
An information processing system including an electronic information board equipped with a touch panel,
Receiving means for receiving electronic file and page information for designating a page of the electronic file;
Extracting a page specified by the page information from the electronic file, storing the extracted page in a storage unit in descending or ascending order, and displaying the page stored in the storage unit using the page information An information processing system including a display control unit that performs the processing can be provided. The electronic file and page information may be received using an e-mail protocol, and the electronic file and page information may be received using an HTTP protocol. Page information is extracted from the file and stored separately from the electronic file.

  Further, according to the present invention, the user who sent the electronic file can be given the editing authority or the access authority for the information stored in the storage means and sent by the user. The present invention further provides an information processing apparatus and program implemented as an electronic information board.

  When there are multiple pages of meeting materials when the meeting information is imported to the network on the electronic information board, the page number that the user wants to use during the meeting is described as page information in the header or body part of the email, or on the web server Upload. The electronic information board simultaneously extracts pages specified by the page information from the conference materials used for the presentation and provides them for the presentation. In the present invention, since the conference material is fetched only for the extracted page number, there is no need to delete unnecessary pages after fetching the page to be used, and both the user PC operation and the presentation operation are performed. Since there is no need to control, a smooth presentation is possible.

  Further, since it is not necessary to delete in advance a page or the like that is not desired to be taken into the electronic information board due to security problems, the use of the electronic information board becomes simpler and more efficient. In addition, when displaying conference materials created on other terminals such as PowerPoint and PDF on the electronic information board and using them, by enabling access to the conference materials for the user who sent the conference materials, It enables page display and editing while ensuring high security, enabling efficient presentation.
