Description

  The present invention relates to a system and method for managing document information, and to an information management method for electronically handling handwritten information entered on paper.

  Even in the modern age of electronic technology, paper documents are still used in large quantities in general offices. The reason is that paper has many advantages such as (1) inexpensive, (2) easy to write, (3) can refer to many sheets at the same time, (4) navigation by the action of `` turning '' It has been. Furthermore, if information about paper documents such as printing contents and writing on paper can be electronically managed in the computer, both the convenience of paper and the multi-functionality of the computer can be enjoyed.

  In recent years, it has become possible to easily digitize information written on paper. In particular, a pen-type input device (digital pen) that electronically acquires the locus of the pen tip on the paper has been put into practical use. The digital pen can input the acquired trajectory of the pen tip into the electronic computer. For example, there is a digital pen developed by Anoto in Sweden. Details of this digital pen are disclosed in International Publication No. 01/71473 (Patent Document 1). The digital pen has the advantage that it can be used easily even by users who are not familiar with the use of keyboards and mice, and it can be applied to various fields such as application management at local government offices as well as document management at general offices. Is expected. With the development of such input devices, it has become easy to digitize writing on paper.

  Based on these technologies, there is a document management technology for managing paper document information and electronic handwritten information in association with each other. For example, in the prior art disclosed in Japanese Patent Laid-Open No. 2005-135211 (Patent Document 2), an electronic document printed on paper is managed, and writing on the paper is digitized and embedded in the electronic document printed on paper. This makes it possible to browse information on paper electronically. Also, in the prior art disclosed in Japanese Patent Laid-Open No. 2006-31172 (Patent Document 3), an electronic document printed on paper is managed as an image, and the image information of the electronic document and the digitized paper It was possible to perform specific processing using handwritten information.

  However, in the prior art, the electronic handwritten information can be used electronically, such as by editing the electronic handwritten information such as deleting, moving the position, and transforming it, and copying the handwritten information to another document. Did not consider. This caused several problems.

  First, when handwritten information is edited, there is a problem that the consistency between information on physical paper and electronic information is lost. For example, when the handwritten information on paper is deleted electronically, there is writing on physical paper, but there is no information on the writing electronically.

  There is also a problem that means for changing the shape of the handwritten information or copying the handwritten information to another document is not prepared. In the technique of Patent Document 2, handwritten information can be copied by copying an electronic document. However, detailed specification such as selection of handwritten information to be copied and change of position cannot be performed. It was limited.

  Furthermore, there has been no means for automatically performing a process of associating handwritten information with a document other than a document corresponding to paper, such as combining the writings entered on different papers by a plurality of users into one document. In the technique of Patent Document 3, there is a means for automatically passing handwritten information to a program that performs certain processing, but this is only for the purpose of performing certain processing by combining handwritten information and a document printed on paper. It was not considered to automatically embed handwritten information in other documents.

  The present invention provides a document management system that allows a user to use handwritten information electronically while electronically holding information expressed on physical paper.

  First, the system configuration will be described. Next, two types of information, paper information and electronic canvas, managed by this system will be described. Finally, a usage example realized by this system will be described.

  The document management system according to the present invention comprises the parts shown in FIG. A document management server 100 that manages information of the entire system and one or a plurality of clients 110 and 120 that are terminals of users of the system are connected via the network 140. Digital pens 111 and 121, which are devices for writing on a paper medium, are connected to the client. A printing apparatus 130 that prints the document content on a paper medium is also connected to the network, and outputs a paper document 131 in response to a user print request.

  The information management unit (storage device) 101 of the document management server 100 manages and stores a database, such as documents and users, described below (FIG. 2). A user information DB 201 that manages information about users, an electronic document information DB 202 that manages information about electronic documents, a paper information DB 203 that manages information about paper on which an electronic document is printed, and a stroke information DB 204 that manages stroke information written on the document. An electronic canvas DB 205 for managing electronic canvas information, and a pipe DB 206 for managing pipe information for automatically copying stroke information of paper information to the electronic canvas. In addition, the document management server 100 includes a calculation unit 102 that performs various arithmetic processes, and a communication unit 103 that performs data communication with a client or a printing apparatus via a network 104.

  Each client receives a print request using a keyboard, mouse, digital pen, and the like, input units 112 and 122 that accept operations from the user such as electronic document editing, and the result of a print request as a result of browsing a document image stored in the information management unit. Display portions 113 and 123 for confirmation and the like are provided.

  In this embodiment, a server-client configuration in which one or a plurality of clients are connected to the document management server will be described. However, a stand-alone configuration in which only one server and one client are connected is substantially equivalent. It becomes processing of. A part of information managed by the information management unit 101 may be managed and stored on the client side.

  In this embodiment, the digital pen disclosed in Patent Document 1 is used as the handwriting acquisition means for the user, but other means or a combination of several means capable of acquiring the paper individual ID and the handwriting stroke may be used. For example, a barcode that represents a paper individual ID is printed on paper, scanned and read to obtain the paper individual ID, a tablet device is placed under the paper, and the strokes entered by the user on the paper are displayed. The paper individual ID and the handwritten stroke may be acquired in combination with the capturing means. In the present embodiment, a digital pen that can simultaneously acquire a paper individual ID and a handwritten stroke by simply writing on paper is taken as an example of means suitable for the present invention.

  Next, the data structure will be described. An example of user information stored in the user information DB 201 is indicated by 300 in FIG. The user information 300 stores a user ID 301 and a user name 302, a printing device ID 303 used by the user, and a digital pen ID 304 used by the user.

  An example of the electronic document information 202 is shown at 400 in FIG. The electronic document information 400 includes an electronic document ID 401, an ID 402 of a user who created the corresponding electronic document, a date and time 403 when the corresponding electronic document was created, a date and time 404 when the corresponding electronic document was last updated, an electronic document content 405, When the total number of pages 406 and the corresponding electronic document are printed, the print information ID 407 having the print condition information is stored. In this embodiment, the contents of the electronic document are expressed in PDF format, and the file name is stored in the electronic document data 405.

  An example of the stroke information 204 is shown in FIG. A stroke 551 on the document 550 in FIG. 5 is represented by information described in items 501 to 506. An item 501 is an ID for identifying the stroke. Item 502 is the ID of the user who has written, and item 503 is the ID of the pen that has been written. An item 504 indicates a stroke entry start time. An item 505 indicates the number of sampling points existing in the stroke. Information on each sampling point is held in the table 520, and an item 506 indicates a pointer indicating the head of the sampling point set corresponding to the stroke. Each sampling point has XY coordinate values 521 and 522 on the document, and the difference between the sampling point entry time and the stroke entry start time described in the item 504 is held in 523. Information is also stored in the data structure as shown in Table 510 for each of the other strokes. Further, even when handwritten characters are input by an input device other than a digital pen, it is possible to manage stroke information using a table 520 that disassembles each stroke and holds the stroke ID, the number of sampling points, the pointer, and the coordinates.

  Next, paper information managed by the system will be described. FIG. 6 shows an outline of the paper information stored in the paper information DB 203. The paper information 600 includes a stroke information list 601, electronic document embedding information 605, and paper information 606. The stroke information list is a list of stroke information entered on paper. The electronic document embedding information is an electronic document printed on paper and print layout information. The paper information is information such as paper size, paper identification information, and other printing date and time. As indicated by reference numerals 610 to 612, the coordinate systems of these pieces of information match.

An example of the paper information is shown in FIG. The paper information 700 includes a paper ID 701, an electronic document ID 702 printed on the paper, a user ID 703 that printed the paper, a paper solid identification information 704, a printed date and time 705, a last date and time 706 when the paper information was updated, A list 707 of user IDs that can access paper information, a paper size 708, print layout information 709 of an electronic document, and a list 710 of stroke IDs entered on paper are stored. The electronic document print layout 709 indicates in which area of the paper medium each content of the electronic document is printed. For example, “D0032154 :: P1 (0,0)-(210,297)-> (0,0)-(210,297)”
Prints the contents of the rectangle (0mm, 0mm)-(210mm, 297mm) on the first page of the electronic document ID D0032154 in the range of (0mm, 0mm)-(210mm, 297mm) on the paper medium. means. Here, the stroke ID 710 corresponds to the stroke information list 601, the printing source electronic document ID 702 and the electronic document print layout 709 correspond to the electronic document embedding information 605, and other information corresponds to the paper information 606.

  Processing related to paper information is shown in FIGS. First, FIG. 8 shows a process for generating paper information by printing an electronic document on paper. When the user instructs the client to print the electronic document 804, the paper document 806 in which the electronic document 804 is embedded in the designated layout is printed by the printer 805 designated by the user. At the same time, electronic document information 807 representing the electronic document 804 and paper information 800 representing the paper document 806 are generated. Here, the printing source electronic document ID in the paper information 800 is equal to the electronic document ID in the electronic document information 807. Also, the paper solid identification information in the paper information 800 is information indicating an identifier embedded in the paper document 806. This identifier is, for example, a dot pattern printed on paper when using the digital pen disclosed in Patent Document 1.

  FIG. 9 shows a process in which writing on a paper document is digitized. When writing 911 is performed on the paper document 910 by the device 912 that reads the handwritten stroke, the stroke information 920 is generated. At the same time, the paper information 900 is acquired from the paper identification information of the paper document 910, and the stroke information 920 is added to the paper information 900. to add.

  FIG. 10 shows a process for displaying the paper information on the client screen. The program stored in the client 1010 acquires the paper information 1000 from the server, and displays the stroke information 1001, the electronic document embedding information 1002, and the paper information 1003 superimposed on each other on the screen. When the user places the cursor 1013 on the stroke 1012 displayed on the screen with a pointing device such as a mouse, the corresponding stroke information 1004 is displayed on the screen (1014).

  The client can display the paper information, but cannot edit, add, or delete the contents of the electronic document or stroke of the paper information (FIG. 11). Due to this limitation, information on physical paper documents can be retained.

  Next, an electronic canvas managed by the system will be described. The electronic canvas is intended to be a work area for freely editing stroke information and electronic documents. The electronic canvas is purely virtual information, and there is no corresponding physical medium like paper information. FIG. 12 shows an outline of the electronic canvas stored in the electronic canvas DB 205. The electronic canvas 1200 includes a stroke information list 1201, electronic document embedding information 1205, and a canvas area 1206. The stroke information list is a list of stroke information registered in the electronic canvas. The electronic document embedding information is information on the electronic document embedded in the electronic canvas and the embedded layout. The canvas area is information indicating the physical size of the work area of the electronic canvas. As indicated by reference numerals 1210 to 1212, the coordinate systems of these pieces of information match.

An example of an electronic canvas is shown in FIG. The electronic canvas 1300 includes an electronic canvas ID 1301, an electronic document ID 1302 embedded in the electronic canvas, an ID 1303 of the user who created the electronic canvas, a created date 1304, a last updated date 1305 of the electronic canvas, A list 1306 of user IDs that can be accessed, a work area size 1307 of the electronic canvas, an embedded layout information 1308 of the electronic document, and a list 1309 of stroke IDs registered in the electronic canvas are stored. The electronic document embedding layout 1308 indicates in which area of the work area each content of the electronic document is embedded. For example, “D0032154 :: P1 (0,0)-(210,297)-> (0,0)-(210,297)”
Means to embed the contents of the rectangle (0mm, 0mm)-(210mm, 297mm) of the first page of the electronic document ID D0032154 in the range of (0mm, 0mm)-(210mm, 297mm) in the work area To do. Here, the stroke ID 1309 corresponds to the stroke information list 1201, the embedded electronic document ID 1302 and the electronic document embedded layout 1308 correspond to the electronic document embedded information 1205, and the canvas area 1307 corresponds to the canvas area 1206, respectively.

  Processing related to the electronic canvas is shown in FIGS. First, FIG. 14 shows a process in which the user generates an electronic canvas through a client. When the user specifies an electronic document 1410, an embedded layout, a canvas area size, and the like through the client, electronic document information 1404 representing the electronic document 1410 and an electronic canvas 1400 are generated. Here, the embedded electronic document ID in the electronic canvas 1400 is equal to the electronic document ID in the electronic document information 1404.

  FIG. 15 shows a process for adding a stroke to the electronic canvas. First, when the electronic canvas 1500 is displayed on the screen of the client 1510 and then a handwriting operation 1512 is performed using a pointing device such as a tablet 1520 or a mouse 1521, stroke information 1505 is generated and added to the electronic canvas 1500.

  FIG. 16 shows processing for displaying the electronic canvas on the client screen. The program stored in the client 1610 acquires the electronic canvas 1600 from the server, and displays the stroke information 1601, the electronic document embedding information 1602, and the canvas area 1603 on the screen. When the user places the cursor 1613 on the stroke 1612 displayed on the screen with a pointing device such as a mouse, the corresponding stroke information 1604 is displayed on the screen (1614).

  FIG. 17 shows a process for editing the stroke of the electronic canvas. First, an electronic canvas 1700 is displayed on the screen of the client 1710, and then a pointing device such as a tablet 1720 or a mouse 1721 is used to rotate, enlarge, reduce, partially cut, or move the stroke 1712 displayed on the screen. When operated, the coordinate information of the stroke information 1704 is updated. If deleted, the stroke information 1704 is deleted from the electronic canvas 1700. In addition to editing strokes, it is also possible to edit electronic documents embedded in the electronic canvas. In this case, the electronic document stored in the electronic document DB 202 is changed.

  FIG. 18 shows a flowchart of the server processing for adding, editing, and deleting the stroke of the electronic canvas described above. In the stroke addition process, when the electronic canvas to which the stroke is added, the information of the operating user, the stroke coordinates and the time stamp information are received (1800), the stroke information is generated in step 1802 and stored in the stroke information DB. In step 1803, the stroke information is added to the electronic canvas. In step 1804, the update time of the electronic canvas is changed to the current time. In the stroke editing process, when the electronic canvas for editing the stroke, the information of the user who is operating, the stroke to be edited, and the information of the stroke editing operation are received (1810), the coordinates of the stroke are calculated in accordance with the stroke editing operation in step 1812. In step 1813, the update time of the electronic canvas is changed to the current time. When the stroke deletion process receives the electronic canvas from which the stroke is deleted and the information about the stroke to be deleted (1820), the stroke information is deleted from the electronic canvas in step 1822, and the update time of the electronic canvas is set to the current time in step 1823. Change to

  FIG. 19 shows a process for copying stroke information of other paper information to the electronic canvas. First, paper information 1900 as a copy source of stroke information and an electronic canvas 1910 as a copy destination are displayed on the screen of the client 1920. Next, the user selects a stroke 1922 on the paper information 1921 displayed by using a pointing device such as the tablet 1930 or the mouse 1931 and performs a copy instruction by dragging and dropping the electronic canvas 1923 displayed. . The client program transmits the instruction to the server, and the server generates new stroke information 1914 from the coordinate value of the stroke information 1904 and the copy instruction information and adds it to the electronic canvas 1910. Note that stroke information of another electronic canvas can be copied to the electronic canvas by the same processing.

  FIG. 20 shows a process for generating the electronic canvas by copying the entire paper information. First, an icon representing the paper information 2000 as a copy source is displayed on the screen of the client 2020. Next, the user instructs to copy the paper information and generate an electronic canvas. The client program transmits the instruction to the server, and the server creates an electronic document embedding information 2012 that is the same as the electronic document embedding information 2002 of the paper information 2000 and a canvas area 2013 that is the same size as the paper size of the paper information 2003 of the paper information 2000. The electronic canvas 2010 is generated, and all the strokes registered in the stroke information 2001 of the paper information 2000 are duplicated and added to the electronic canvas 2010. A new electronic canvas can be generated by copying the entire electronic canvas by the same process.

  FIG. 21 shows a flowchart of server processing for copying stroke information from paper information to the electronic canvas and generating an electronic canvas from the paper information. When the stroke information copy process receives the copy source stroke information, the copy destination coordinates, the copy destination electronic canvas information, and the information of the user who is operating (2100), the coordinates are calculated based on these information in step 2102. New stroke information is generated and registered in the stroke information DB. The stroke information generated in step 2103 is registered in the electronic canvas. In step 2104, the update time of the electronic canvas is changed to the current time. When the electronic canvas generation processing from the paper information receives the copy source paper information and the information of the operating user (2110), in step 2112 the electronic document embedding information same as the electronic document embedding information of the paper information and the paper information An electronic canvas having a canvas area having the same size as the paper size of the paper information is generated and registered in the electronic canvas DB, and the stroke information is duplicated in step 2114 for each piece of paper information in the iterative processing 2113. The generated stroke information is registered in the stroke information DB, and the stroke information generated in step 2115 is registered in the electronic canvas.

  Next, a process of automatically copying the stroke information to a specific position on the electronic canvas when the digitized stroke information is added to the paper information will be described with reference to FIGS. An overview of this process is shown in FIG. In order to automatically copy the stroke information, a pipe 2220 that connects one area of the paper information 2200 and one area of the electronic canvas 2210 is registered in the pipe DB 206 in advance. At this time, when the stroke 2232 entered by the stroke input device 2231 such as a digital pen is digitized in the paper document 2230 and is registered in the paper information 2200 as the stroke information 2204, the area of the paper information 2200 to which the pipe 2220 is connected. Is overlapped with the coordinates of the stroke information 2204, new stroke information 2214 obtained by converting the coordinate value of the stroke information 2204 onto the connection destination area of the pipe 2220 is generated and registered in the electronic canvas 2210.

  An example of pipe information 206 is shown in FIG. The pipe 2300 includes a pipe ID 2301, a paper information ID 2302 to which the pipe is connected, a paper information area 2303 to which the pipe is connected, an electronic canvas ID 2304 to which the pipe is connected, and an area 2305 on the electronic canvas to which the pipe is connected. Store.

  FIG. 24 is a flowchart of server processing for automatic stroke information copying using a pipe. When the digitized stroke information and the paper information to which the stroke information is added are received (2400), all the pipes having the paper information ID as the connection source ID are acquired from the pipe DB 206 in step 2401, and in the repetition process 2402 For each acquired pipe, it is determined in step 2403 whether or not the coordinates of the stroke information and the connection source area of the pipe overlap, and if they overlap, a common part of the stroke and the connection source area is cut out in step 2404. The coordinate value of the part cut out in 2405 is converted from the coordinate system of the connection source region to the coordinate system of the connection destination region, and stroke information having the coordinate value converted in step 2406 is newly generated to be displayed on the connection destination electronic canvas of the pipe. sign up.

  The user can create a pipe using any paper information as a connection source and any electronic canvas as a connection destination at any time. Further, when the electronic canvas is generated by copying the paper information shown in FIG. 20, a pipe having the copy source paper information as the connection source and the copy destination electronic canvas as the connection destination can be generated as a prescribed process.

Next, operations realized by the present invention will be described with reference to FIGS.
First, since this document management system prohibits editing of stroke information of paper information from a client, it is ensured that information on physical paper is correctly held electronically. 25 and 26 explain what inconvenience occurs when the stroke information of the paper information is edited from the client. Assume that paper information 2502 corresponding to the paper document 2505 is stored in the server 2500, and two pieces of stroke information 2503 and 2504 entered in the paper document 2505 are registered in the paper information 2502. Assume that the stroke information 2503 is deleted from the paper information 2502 by the client 2506. Then, when the paper information 2502 is displayed on the screen of the client 2506, only one stroke is displayed. However, since there are two strokes on the paper surface of the paper document 2505, the physical information and the electronic information are displayed. Consistency is lost. FIG. 26 shows a function for displaying paper information on the screen of the client 2603 when a paper document 2601 is clicked with the digital pen 2602 or the like. When this is done, physical information matches electronic information. If the property is not maintained, the effectiveness of the function is impaired. For example, even if the user clicks on paper to display the paper information 2502 on the screen of the client 2506 in order to check who has entered the stroke on the paper document 2505, the stroke information 2503 has been deleted, so The situation that cannot be examined occurs. In the present document management system, consistency between a physical paper document and electronic paper information is maintained, so such a situation does not occur.

  Next, an example in which strokes written by different people on different paper documents are combined into one electronic canvas will be described with reference to FIG. First, the electronic document is printed as three paper documents 2700, 2710, and 2720. Then, an electronic canvas 2730 in which the same electronic document is embedded is generated, and a pipe that connects the paper information corresponding to the paper documents 2700, 2710, and 2720 and the electronic canvas 2730 is generated. At this time, when the user writes the stroke 2701 on the paper document 2700, the stroke information is added to the paper information and the stroke information 2731 is also added to the electronic canvas 2730 by the pipe. Similarly, a stroke 2711 entered by another user in the paper document 2710 is also added as stroke information 2732 to the electronic canvas 2730.

  FIG. 28 shows information stored in the database at this time. The paper information DB 203 stores paper information 2800, 2801, and 2802 corresponding to the three paper documents 2700, 2710, and 2720, and the electronic canvas DB 205 stores the electronic canvas 2730, which are stored in the electronic document information DB 202. The electronic document information 2820 stored in is stored. Three pipes 2830, 2831, and 2832 are stored in the pipe DB 206, and the paper information 2800 and the electronic canvas 2730, the paper information 2801 and the electronic canvas 2730, and the paper information 2802 and the electronic canvas 2730 are connected to each other. The stroke information DB 204 stores stroke information 2701, 2711, and 2721 registered in the respective paper information and stroke information 2731, 2732, and 2733 registered in the electronic canvas 2730 by pipes.

  As an application example of the function of combining strokes entered in separate paper documents into one electronic canvas, handwritten annotations on conference materials can be considered (FIG. 29). If the meeting materials are printed in advance to generate paper documents 2900, 2910, and 2920, and all the paper information is connected to one electronic canvas 2931 through a pipe, the electronic canvas 2931 is displayed on the display 2930 of the conference hall. As a result, handwritten annotations 2902, 2912, 2922 written by each participant in the conference material are combined and displayed on the real-time display 2930.

  Further, as another application example, counting of questionnaires can be considered (FIG. 30). Questionnaire entry forms 3000, 3010, and 3020 are printed, and all pieces of paper information are connected to one electronic canvas 3031 by pipes. Then, the questionnaire response entered in the questionnaire entry form is registered in the electronic canvas 3031. If the client program that displays the electronic canvas 3031 has a function for switching the stroke entry list and the stroke to be displayed by selecting the stroke entry person, it is possible to easily view the questionnaire responses of each respondent by switching the stroke display. it can.

  Finally, the paper information and electronic canvas access method from the client will be described with reference to FIGS.

  FIG. 31 shows a process for displaying paper information from a file having a reference to the paper information. The paper information reference file 3101 stores information that can uniquely identify paper information, such as a URL of a document management server and a paper information ID. When this is selected on the client 3100, the client 3100 communicates with the server 100 to acquire paper information and display the information on the screen. The paper information reference file is generated by the client when paper information is generated by printing paper. Further, for example, a paper information reference file for the paper information can be created after accessing the paper information using a search function described below.

  Similarly, an electronic canvas can be displayed from a file having a reference to the electronic canvas. This process is shown in FIG. The electronic canvas reference file 3201 stores information for uniquely identifying the electronic canvas, such as the URL of the document management server and the electronic canvas ID. When this is selected on the client 3200, the client 3200 communicates with the server 100 to acquire the electronic canvas and display information on the screen.
