Each embodiment will be described below with reference to the drawings.
FIG. 1 is a diagram showing a conference system 100 (command transmission system).
First, the purpose of the conference system 100 will be described.
In general, in a meeting, a document file is prepared as a material for explaining the content of the discussion, and the discussion proceeds while referring to the document file. However, the document file is not always referred to in order according to the progress. . For example, supplementary information such as detailed data that does not follow the flow of explanation is often provided by being collected at the end of the document file or in another document file. Moreover, it may refer back to the page image referred to in the past regardless of the progress of the discussion. Therefore, there is a need for a conference system 100 that not only sends page images in a document file in order, but also can easily display page images in a document file to be referred to at random and can also display supplemental information at random.

Therefore, the purpose of the conference system 100 according to the present embodiment is to “acquire position information in a page image in a document file and associate an instruction corresponding to the page image with the acquired position information, as described in the background art. More specifically, the purpose of the conference system 100 is, for example, a reduced image of a page image to be referred to even if the user does not know the page number of the document file to be referred to. It is to provide a technology that can easily display information related to an instructed page image, such as being able to display information such as a page image to be referred to by simply instructing on a digital pen or tablet.
Furthermore, the conference system 100 simultaneously aims to achieve additional objectives described below.

In recent years, document files have been displayed on a display, a tablet PC, a slate PC, a portable terminal device, etc. without being printed on a sheet due to a paperless flow for the purpose of increasing environmental awareness and cost reduction. Is called. At present, such paperless attempts are not widespread due to the aspect of reducing business efficiency, but environmental measures are becoming more important every year due to problems such as global warming. Yes.
Therefore, the conference system 100 can easily display the display information corresponding to the page image designated by the user, and can reduce the amount of paper used without reducing the work efficiency even if it does not become completely paperless. Providing technology is one of the purposes.

The conference system 100 includes a PC 11 (Personal Computer), a server 2 (server device), projectors 12 and 13, a wireless LAN access point 14, an MFP 15 (Multi Function Peripheral, printing device), a portable terminal device 16 (hereinafter referred to as a terminal device 16). Description), a Nin1 display sheet 17 (Nin1 display page), and a digital pen 18 (information acquisition device).
Each device 11-16 is connected with the server 2 via LAN. The LAN is connected to the external Internet W. The PC 11 creates a document file used in the conference and inputs it to the server 2. The document file is, for example, a presentation material and includes a plurality of pages. The Nin1 display sheet 17 is printed by the MFP 15 based on the document file. On the Nin1 display sheet 17, N (an integer greater than or equal to 2) page images 31 in the document file are reduced and arranged. The Nin1 display sheet 17 is distributed to each participant in the conference. The digital pen 18 communicates wirelessly with the specific terminal device 16 associated with the digital pen 18. The terminal device 16 is prepared for the participants of the conference.

The overall operation of the conference system 100 will be briefly described.
First, when the meeting starts, the server 2 transmits a document file as a presentation material to each terminal device 16. The presenter of the presentation makes a presentation using his / her PC 11 while sending the page images 31 in the document file one page at a time. The presenter causes one projector 12 to display the page image 31 displayed by the presenter's terminal device 16, or causes the other projector 13 to display a shared screen other than the page image 31 displayed by the presenter's terminal device 16. be able to. The participant's terminal device 16 is normally synchronized with the presenter's terminal device 16, and the participant's terminal device 16 has information indicating a page image displayed on the presenter's terminal device 16. It is transmitted from the terminal device 16 via the server 2. Accordingly, the participant's terminal device 16 displays the page image displayed by the presenter's terminal device 16 in the document file held by the participant.

FIG. 2 is a diagram for explaining the effect of the conference system 100.
As described above, N page images 31 in the document file are reduced and arranged on the Nin1 display sheet 17 distributed to each participant.
In the presentation by the presenter, when the presenter displays the page image of the eighth page on the terminal device 16 as a reference page, the terminal device 16 of the participant synchronized with the terminal device 16 also receives the page image 31 of the eighth page. Is displayed. At this time, the participant brings the digital pen 18 into contact with the page image 31 to be referred to on the Nin1 display sheet 17, for example, the page image 31 on the sixth page. Then, the digital pen 18 acquires position information indicating the coordinates with which the digital pen 18 in the Nin1 display sheet 17 has touched, and transmits it to the terminal device 16. The terminal device 16 transmits the position information to the server 2. The server 2 determines from the position information that the page image 31 of the sixth page has been instructed by the digital pen 18 and instructs the terminal device 16 to display the page image 31 of the sixth page in the document file held by the terminal device 16. Send a command to When the participant's terminal device 16 receives the command, it displays the page image 31 of the sixth page.

  As described above, in the conference system 100, the participant simply indicates the page image 31 to be referred to on the Nin1 display sheet 17 with the digital pen 18, and easily displays the page image 31 to be referred to on the participant's terminal device 16. be able to. Further, in the conference system 100, since each page image 31 of the document file is referred to by the terminal device 16 without printing the document file on a sheet, it is possible to reduce the amount of paper used without reducing business efficiency.

Hereinafter, a specific configuration of the conference system 100 will be described.
FIG. 3 is a block diagram showing a hardware configuration of main elements of the conference system 100. In FIG. 3, the wireless LAN access point 14 that relays the connection of the terminal device 16 to the LAN is omitted.
Based on the Nin1 display page 17 which is print data transmitted from the server 2, the MFP 15 uses the page image 31 in which the page images 31 (arrangement target page images) in the N document files are reduced and arranged on the sheet. Print. This sheet is referred to as a Nin1 display sheet 17. On the Nin1 display sheet 17, before the image is formed, fine dots are printed on the entire surface of the Nin1 display sheet 17 in a state of being slightly shifted from the 0.3 mm orthogonal grid. The MFP 15 uses a sheet on which dots are formed as described above as a sheet to be printed. The dot pattern on each sheet is unique for each sheet.

  The digital pen 18 is, for example, Anotopen (registered trademark). The digital pen 18 is used, for example, by bringing the tip thereof into contact with a page image 31 reduced and printed on the Nin1 display sheet 17. When the digital pen 18 comes into contact with the Nin1 display sheet 17, the digital pen 18 reads a dot pattern within a predetermined size area (within a 6 × 6 dot area) on the Nin1 display sheet 17. The digital pen 18 digitally processes the read dot pattern as data indicating position information on the Nin1 display sheet 17 and identification information of the Nin1 display sheet 17 (identification information of the Nin1 display page 17 which is print data described later). To the terminal device 16.

  The digital pen 18 includes a CCD 181 (Charge Coupled Device) as an image sensor, a battery 182, a processor 183, a memory 184, a wireless communication unit 185, a writing pressure sensor 186, and a pen core 187. Since the digital pen 18 includes the pen core 187, it is possible to write characters by moving the digital pen 18 in contact with the Nin1 display sheet 17. The pen pressure sensor 186 detects the contact pressure when the tip of the digital pen 18 contacts the Nin1 display sheet 17. The CCD 181 operates, for example, under conditions such that the contact pressure is equal to or higher than a threshold value, and reads the dot pattern on the Nin1 display sheet 17. When the digital pen 18 moves while being in contact with the Nin1 display sheet 17, the CCD 181 reads the dot pattern on the Nin1 display sheet 17 along the movement path of the digital pen 18.

The processor 183 digitally processes the dot pattern to be read as stroke data indicating the position information on the Nin1 display sheet 17 and the identification information of the Nin1 display sheet 17, and transmits the data to the terminal device 16.
The terminal device 16 receives the identification information of the Nin1 display sheet 17 and the position information on the Nin1 display sheet 17 from the digital pen 18 and transmits them to the server 2 together with the terminal device identification information that can identify the terminal device 16. When these pieces of information are transmitted to the server 2, the server 2 generates a command based on these pieces of information and transmits the command to the terminal device 16. The terminal device 16 receives the command and performs an operation according to the command.

  When the position information pointed to by the digital pen 18 points to the page image 31 that is reduced and arranged on the Nin1 display sheet 17, the command displays the page image 31 that has been reduced on the Nin1 display sheet 17, for example. This is a reference instruction to display only one image on the device 16. In the present embodiment, even if the position information indicated by the digital pen 18 is the same position coordinate, the type of command output by the server 2 can be switched by switching the operation mode set in the server 2. . In the above description, the case where the operation mode is set to the reference mode has been described as an example.

  For example, the operation mode can be set to a print mode and an edit mode. When the operation mode of the server 2 is set to the print mode, even if the position information indicated by the digital pen 18 points to the page image 31 that is reduced and arranged on the Nin1 display sheet 17, the command is digital. This is a print instruction for causing the terminal device 16 to print the page image 31 indicated by the pen 18. The terminal device 16 can transmit an operation mode setting request for switching the command type to the server 2.

  The terminal device 16 includes a display panel 161, a wireless communication unit 162, an operation input unit 163, a processor 164, an ASIC 165 (Application Specific Integrated Circuit), a memory 166, and an HDD 167 (Hard Disk Drive). The display panel 161 is, for example, a touch panel. The wireless communication unit 162 communicates with the digital pen 18 and also communicates with the wireless LAN access point 14. The processor 164 reads the program from the memory 166 and executes it to control the entire terminal device 16 and realize various functions. The ASIC 165 may perform part or all of the processing performed by the processor 164. The operation input unit 163 receives a user operation input. The operation input unit 163 is a touch panel and may be integrated with the display panel 161 or a button. When the operation input unit 163 receives the operation input, the terminal device 16 can transmit a setting request for a predetermined operation mode to the server 2.

The server 2 receives the identification information of the Nin1 display sheet 17, the position information in the Nin1 display sheet 17, and the terminal device identification information from the terminal device 16. The server 2 generates a command based on the identification information of the Nin1 display sheet 17, the position information on the Nin1 display sheet 17, and the operation mode, and transmits the command to the terminal device 16 identified from the terminal device identification information. .
The server 2 includes a display 201, a wireless communication unit 202, an operation input unit 203 such as a keyboard, a processor 204, an ASIC 205, a memory 206, and an HDD 207. The processor 204 reads the program from the memory 206 and executes it to control the entire server 2 and realize various functions.

FIG. 4 is a functional block diagram of the server 2.
The server 2 includes a generation request acquisition unit 211, a file acquisition unit 212, a Nin1 display page generation unit 213, a table generation unit 22, a storage unit 23, an operation mode setting unit 24, an acquisition target setting unit 25, and a command setting unit as functional units. 26, a command acquisition unit 27, a transmission / reception unit 28 (transmission unit, reception unit), and an input reception unit 29. These functional units are functions of the server 2 that are realized by including a later-described conference reservation system (software) of the server 2 and hardware configurations 201 to 207. The input receiving unit 29 receives an operation input signal input from the operation input unit 203 or the like that has received a user operation input. The description of other functional units will be described later. Each functional unit is assumed to be on one server 2, but may be distributed on a plurality of servers connected to each other via a LAN. A plurality of servers may cooperate to realize the functional unit.

Hereinafter, the processing of the server 2 in the conference using the conference system 100 will be described together with the processing of other elements such as the PC 11. 5 and 6 are flowcharts for explaining the flow of processing of the server 2 and processing of other elements.
The presenter creates a document file for presentation using the PC 11 (Act 1). The format of the document file is, for example, PDF (Portable Document Format) or XPS (XML Paper Specification). In the document file, for example, link information to other pages of the document file, link information to an external reference document, and link information to a website on the external Internet W are embedded as meta information. Other meta information embedded in the document file includes attribute information such as the creator of the document file and the update date.
The presenter registers the document file in the server 2 via the LAN. At this time, the presenter stores the document file in a predetermined conference folder in the server 2 by using the conference reservation system installed in the server 2 in association with the conference start time, end time, and prospective participants. (Act2).

  Participants of the conference authenticate to the conference reservation system of the server 2 using the terminal device 16 used in the conference. When the participant's terminal device 16 is authenticated by the conference reservation system of the server 2, the server 2 automatically transmits the document file in the conference folder corresponding to the authenticated terminal device 16 to the terminal device 16 (Act 3).

  For example, the conference reservation system of the server 2 generates a Nin1 display page as print data on condition that authentication of a certain number or more of terminal devices 16 is approved. In other words, when the conference reservation system of the server 2 approves the authentication of a certain number or more of the terminal devices 16, the generation request acquisition unit 211, which is a functional unit of the server 2, acquires a generation request for the Nin1 display page. Subsequently, the file acquisition unit 212 acquires the document file requested to generate the Nin1 display page.

Then, as shown in FIG. 7, the Nin1 display page generation unit 213 generates, as print data, a Nin1 display page 17 in which N page images 31 in the document file registered in the server 2 are reduced in size.
The table generation unit 22 arranges, for example, eight reduced page images 31 in one Nin1 display page 17. Therefore, for example, when the page image of the document file is up to the 60th page, the table generation unit 22 displays the Nin1 display page 17 for 8 pages (7 page × 8 page image + 1 page × 4 page image). Is generated. In addition, the table generation unit 22 provides a writing area 32 for participants to take notes on the side of the reduced-ordered page image 31 in each Nin1 display page 17. Note that the Nin1 display page 17 is print data, and the Nin1 display sheet 17 on which an image is formed based on the Nin1 display page 17 is a sheet. The page image 31 and the retouched area 32 are the same, and the same reference numerals are used for data and images on the sheet.

FIG. 8 shows the command table 4.
The table generation unit 22 generates the command table 4 for each Nin1 display page 17, and stores each command table 4 in the storage unit 23 in association with the identification information of each Nin1 display page 17 (Act4). In each command table 4, the operation mode is associated with the position information in the area of the page image 31 reduced in the Nin1 display page 17 or the position information around the area of each page image 31. Are associated with commands related to the page image 31.
In this embodiment, there are three operation modes: a reference mode, a print mode, and an edit mode. The commands associated with these commands are operation commands. The command is a collection of keyboard events for operating an OS (Operating System) and applications operating on the terminal device 16. A command is a keyboard event code that emulates keyboard input.

In general, a method for operating an application includes a GUI (Graphical User Interface) -based menu that is operated using a mouse cursor using a mouse or a touch pad. For example, when displaying a window for displaying a specific page image, if the menu “page navigation” is selected, a pull-down menu as shown in FIG. 9 is displayed, and then “page (Shift + Ctrl + N)” is selected. When selected, a pop-up window for inputting a page number as shown in FIG. 10 is displayed.
When the page number to be displayed is input from the keyboard to the pop-up window, the application jumps to the specified page number and displays the page image of the specified page number. Commands that use a CUI (Command User Interface) -based method (keyboard navigation) in which the same operation is performed with a keyboard without using a mouse are commands associated with each operation mode in the command table 4.

When (Shift + Ctrl + N) displayed in “Page (Shift + Ctrl + N)” in FIG. 9 is input to the application as a keyboard event, a pop-up window for inputting the page number in FIG. 10 is displayed. When the page number to be displayed (for example, 1 for one page) is input as a keyboard event, the same operation as that performed with the mouse or touch pad described above is realized. A collection of keyboard event codes as described above is a command, and the application can be operated by inputting this command to the application.
In the command table 4, (Shift + Ctrl + N) and ↓ 6 ↓ are associated with the reference mode in the position information (X1, Y1)-(X2, Y2) as commands. ↓ means input of ENTER. The meaning of the position information (X1, Y1)-(X2, Y2) means that the position information that is the coordinate information is in the range of (X1, Y1)-(X2, Y2). The range where the position information is (X1, Y1)-(X2, Y2) is the range of the rectangular area, and the vertices facing each other at the vertices where the sides of the rectangular area intersect are (X1, Y1)-(X2, Y2). The range of the rectangular area.

  In the present embodiment, the position information (X1, Y1)-(X2, Y2) is the page image 31 of the sixth page in the document file in the Nin1 display page 17 (Nin1 display sheet 17), and a reduced arrangement. This is position information indicating a region on the page image 31 that has been set. Therefore, in the present embodiment, when the digital pen 18 is brought into contact with the page image 31 of the sixth page on the Nin1 display sheet 17 and the page image 31 of the sixth page is designated, the page image 31 of the sixth page in the document file. Is transmitted to the terminal device 16. When the terminal device 16 receives the command, the pop-up windows shown in FIGS. 9 and 10 are continuously displayed on the terminal device 16, and then the page image 31 of the sixth page in the document file is displayed on the display panel 161. Is displayed.

In the command table 4, the reference mode at the position coordinates (X5, Y5)-(X6, Y6) has “C: \ Program Files \ Internet Explorer \ iexplore.exe” http://www.yahoo.co. jp ↓
Are associated.
This command is a command for causing the terminal device 16 to open a website whose address is http://www.yahoo.co.jp via the Internet W. As such a command as link information, a command for opening a page image of another document file stored in the terminal device 16 or the like, or a predetermined page image of a term dictionary stored in the terminal device 16 or the like is opened. Command may be used.
In the command table 4, (Ctrl + P), ↓ 6 ↓↓ is associated with the print mode in the position information (X1, Y1) − (X2, Y2) as commands. When the command is transmitted to the terminal device 16, the pop-up window shown in FIG. 11 is displayed on the terminal device 16, and then the print data of the page image 31 of the sixth page in the document file is received from the terminal device 16. The page image 31 of the sixth page is printed by being transmitted to the MFP 15 or the like.
In the command table 4, the editing mode in the position information (X1, Y1)-(X2, Y2) is associated with (Shift + Ctrl + N) and ↓ 6 ↓ (Ctrl + 6) ↓ as commands. When the command is transmitted to the terminal device 16, a pop-up window shown in FIG. 12 is displayed on the terminal device 16, and the page image 31 of the sixth page in the document file is edited on the display panel 161 of the terminal device 16. Is possible.

By the way, the table generation unit 22 displays the position information on the Nin1 display page 17 of the set position set corresponding to each page image 31 on the Nin1 display page 17 and the page image 31 corresponding to the position information. Corresponds with the related command.
Specifically, in the present embodiment, as illustrated in the flowchart of FIG. 13, the generation request and the document file of the Nin1 display page 17 are acquired by the generation request acquisition unit 211 and the file acquisition unit 212 of the server 2 and the Nin1 display is displayed. When the page generation unit 213 generates the Nin1 display page 17 (Act 40), the table generation unit 22 extracts link information from each page image 31 (Act 41).
If the position information associated with the link information in each page image 31 is larger than a predetermined size (Act 42: YES), the link information corresponds to, for example, a relatively long sentence (the phrase “A company's new product”). When attached, the table generation unit 22 sets a setting position corresponding to each page image 31 associated with the link information in the Nin1 display page 17, for example, the page image 31 of the fifth page. A command based on the link information (a command set in association with the page image 31) is associated with the position information on the Nin1 display page 17 in the upper left position information (Act 42).

That is, in the page image 31 of the fifth page, when the link information is associated with the upper left position information in the page image 31 of the fifth page, the table generating unit 22 selects the page of the fifth page. Also in the Nin1 display page 17 in which the image 31 is reduced and arranged, as shown in FIG. 7, the link information is added to the position information in the Nin1 display page 17 located at the upper left in the page image 31 of the fifth page. Map commands based on it.
On the other hand, when link information is associated with a short sentence or a small object, and the position information associated with the link information in each page image 31 is equal to or smaller than a predetermined size (Act 42: NO), the table generation unit 7, as shown in FIG. 7, in the Nin1 display page 17, for example, the periphery of the page image 31 of the first page associated with the link information, for example, below the page image 31 of the first page. A command based on the link information is associated with the position information (Act 44). Further, the table generation unit 22 has a link notation 50 indicating that the command based on the link information is set in the position information portion below the page image 31 to which the command based on the link information is associated on the Nin1 display page 17. Is added (Act 45).

After Acts 42 and 45, the table generating unit 22 associates a command for displaying each page image 31 on the terminal device 16 for each position information indicating the area of each page image 31 (Act 46). At this time, if the command corresponding to the link information is associated with the position information in the page image 31, the table generating unit 22 excludes the position information portion associated with the command corresponding to the link information. A command for displaying one page image 31 is associated with the position information in the page image 31.
As described above, the table generation unit 22 generates the command table 4 for each Nin1 display page 17 and associates it with each Nin1 display page 17. At this time, the operation mode setting unit 24 sets the initial setting of the operation mode to the reference mode for each terminal device 16. The acquisition target setting unit 25 sets the initial setting of the Nin1 display page 17 for which position information is acquired for each terminal device 16 to the Nin1 display page 17 of the first page.

Due to the functions of the functional units of the server 2 described above, the initial setting of the operation mode and the location information acquisition target are stored in the storage unit 23 for each of the terminal devices A and B participating in the conference as shown in FIG. A first table 231 associated with the initial setting of the Nin1 display page 17 is stored. Further, as shown in FIG. 15, the second table 232 in which the command table 4 is associated with each Nin1 display page 17 is stored in the storage unit 23 by the function of each functional unit of the server 2.
Subsequently, the transmission / reception unit 28 transmits the Nin1 display page 17 as print data to the MFP 15 together with a print instruction for the terminal device 16 authenticated by the server 2 (Act 5). The MFP 15 prints the Nin1 display sheets 17 for the number of participants in the conference (Act 6). The printed Nin1 display sheet 17, the digital pen 18, and the terminal device 16 are distributed to each participant one by one.
