Moreover, not only one user but also a plurality of users can simultaneously perform such an organization work, and a plurality of users can efficiently collaborate such as examining a policy while browsing a plurality of documents. Can be realized.

  On the other hand, a method of displaying a document image on a computer display screen directly processes electronic data (document data) of the document, so that rearrangement of document data that can be directly used for various information processing, etc. It can be performed. However, in this method, since documents are displayed on a display screen of a limited size, it is difficult for a plurality of users to view and work on a plurality of documents at the same time, and to handle these documents by hand. Cannot be used in such a manner that the user can easily grasp it sensuously.

In recent years, as a display recording medium for viewing documents that can replace paper, which is a paper medium, document images can be displayed and held on the display unit in a non-powered state, and are flexible, thin and portable like paper An electronic paper is being developed.
Electronic paper is a display device having a display unit that displays and holds an image in a non-powered state. When the image is roughly classified according to the writing format of the image on the display unit, a document image is automatically displayed on the display unit based on electronic data. There are self-writing type electronic paper having a writing function and optical writing type electronic paper for holding a projected document image on a display unit.
Unlike electronic paper, such electronic paper can erase and overwrite the image displayed and held on the display unit, and can update and erase the document image displayed and held for repeated use. Use promotion is also desired from the viewpoint of saving paper resources.

Here, regarding such electronic paper, an invention has been proposed in which the electronic paper can be attached to and detached from the electronic paper file and an image display process is performed on the display unit in accordance with the attached / detached state (see Patent Document 1).
Further, an invention has been proposed in which a plurality of document data associated in advance is wirelessly transmitted to a plurality of electronic papers and displayed on each electronic paper (see Patent Document 2).

Japanese Patent Laid-Open No. 2001-31227 JP 2002-91749 A Japanese Patent Laid-Open No. 2002-300333

  A display recording medium represented by electronic paper, as described above, displays and holds different documents on a plurality of display recording media, and allows a user to visually grasp the contents of these documents in a list. These display recording media can be rearranged and the order of overlap can be rearranged so that the relevance between these documents can be easily organized, and this sort of work can be performed not only by one user. A plurality of users can be performed simultaneously.

However, the display recording medium can be used in such a manner that the user can handle the document by arranging the display recording medium in a handy manner. As a result, it is impossible to reflect the results treated in this way in document data, and it is impossible to use user operations such as arranging display recording media (that is, documents) for various information processing on document data.
As in the case of a document printed on paper, it is conceivable to read and digitize a document displayed and held on a plurality of display recording media with a digital camera or a scanner. Since only one image data including a document can be obtained, it is not possible to use the document data for various information processing.

  The present invention has been made in view of the above-described conventional circumstances, and realizes associating a user's placement operation performed on a display recording medium for displaying and holding a document with the document data so that the user can handle the document data. It aims to realize an environment that can be operated as if it were handled by a user.

  The present invention provides a portable display recording medium that displays and holds a document image, and includes a detection means, a data acquisition means, and a data management means, and the detection means detects that another display recording medium is adjacent. The data acquisition unit acquires identification data for identifying a document to be displayed and held from the other display recording medium, and the management unit manages the identification data acquired in association with the adjacent positional relationship with the other display recording medium.

  Therefore, when the user takes the display recording medium and changes the stacking order of the plurality of bundled display recording media or changes the arrangement of the plurality of display recording media placed on the plane, Document identification data is managed in association with the adjacency relationship (up and down in the thickness direction, up and down and left and right in the plane) between the display recording media changed by the operation. That is, original document data (electronic data) specified by document identification data such as a document ID is associated with the adjacent relationship between display recording media.

  Here, the identification data for identifying the document is the document ID assigned to each document data, and if each document and each display recording medium for displaying and holding the document are uniquely associated, each display recording medium can be identified. The given medium ID can also be used. In this case, when the document is displayed and held on the display recording medium, it is not necessary to hold the document ID on the display recording medium. Therefore, the burden on the display holding process and the function on the display recording medium can be reduced. Can do.

  Further, the present invention detects that the display recording medium is adjacent to another display recording medium, acquires identification data of a document to be displayed and held from the other display recording medium, and The identification data acquired in association with the adjacent positional relationship is managed, the management device acquires the identification data associated with the positional relationship from the display recording medium, and the identification is associated with the positional relationship acquired from the plurality of display recording media Integrate data with related data.

  Therefore, when the user takes the display recording medium and changes the stacking order of the plurality of bundled display recording media or changes the arrangement of the plurality of display recording media placed on the plane, Document identification data is managed for each display recording medium in association with the adjacent relationship between the display recording media changed by the operation, and the management device acquires identification data associated with the positional relationship from these display recording media. All the display recording media (that is, documents) that are adjacent to each other are integrated into relationship data associated with the positional relationship between the display recording media. That is, relationship data in which each identification data is associated with the positional relationship of all the display recording media that are bundled or arranged in a plane and connected in an adjacent relationship is obtained, and the original document data is the adjacent relationship between these display recording media. Are associated with each other.

Further, according to the present invention, the recognition device detects a positional relationship between a plurality of adjacent display recording media, and identifies a document to be displayed and held from the display recording media in association with the detected positional relationship between the display recording media. The identification data is acquired, the management device acquires identification data associated with the positional relationship from the recognition device, and manages the identification data associated with the acquired positional relationship as the relationship data.
Therefore, instead of the display storage medium, the adjacent relationship between the display storage media is detected by an external recognition device, and in the same manner as described above, the management device acquires the identification data associated with the positional relationship, and all the adjacent relationships are obtained. The display recording medium (that is, the document) is integrated into relation data associated with the positional relation between the display recording media.

Further, the present invention sets, for example, an area for arranging the display recording medium on a table or a wall surface, and the positional relationship between the areas in accordance with the arrangement of the display recording medium in the area. In order to manage the document, the recognition device detects the display recording medium existing in the preset area, acquires identification data for identifying the document to be displayed and held from the detected display recording medium, the management device, Identification data is acquired from the recognition device, and the acquired identification data is managed as relation data associated with the area where the display recording medium is detected.
Therefore, for example, it is possible to reflect a result of a conference held by a plurality of users while arranging a document by surrounding a table in which an area for classifying the document is arranged in the document data via the document identification data.
In the present invention, the user can select and use a template that is a pattern for setting an area, and the template can be updated to a new one.

  Here, the relational data obtained as described above is used when information processing is performed on the original electronic data (document data) of the document image displayed and held on the display storage medium. The document image based on the document data is displayed on the display screen according to the adjacent relationship or the positional relationship of the region and used for the document data, or the document data is filed or linked for each region based on the relationship data. It is possible to perform a process of association.

  According to the present invention, since the positional relationship of the display recording medium that displays and holds the document is associated with the document identification data, the user operates the display recording medium so that the document data can be handled as if it were hand-held. Can be operated.

The present invention will be specifically described based on an example.
First, a basic configuration of an example of a display recording medium used in the present invention will be described with reference to FIGS.
The display recording medium shown in FIGS. 12 to 19 is a medium referred to as electronic paper, and is roughly divided according to the document image recording method, and is shown in FIGS. 12 to 15 and FIGS. 16 to 18. There is a self-writing type, and it is a thin device like paper so that it can be called so-called electronic paper.

FIG. 12A shows the optical writable electronic paper EP viewed from the front, and FIG. 12B shows the optical writable electronic paper EP viewed from the side. The electronic paper EP shown in the figure has a display unit 2 for displaying and holding document images and a processing unit 3 for performing communication and various processes according to the present invention. The built-in functions are also shown.
The optical writable electronic paper EP is a flexible thin thin film, for example, as large as A4 size paper, and the processing section 3 is provided on one piece of the display section 2 that occupies most of the area.
In addition, the magnitude | size of the display part 2 is arbitrary, can also be used as a tag or a card | curd, and shall be the magnitude | size according to a use. Moreover, it can also be set as the structure which made the display part 2 and the process part 3 detachable so that it may mention later.

The processing unit 3 includes an electrode 4 for applying a voltage for driving the display unit 2, a communication unit 5 for communicating data with the outside wirelessly, a memory 6 for holding electronic data in a readable and writable manner, and the present invention. A processor 8 that performs various processes, a battery 8 that supplies driving power for the communication unit 5, the processor 7, and the like are provided.
The optical writable electronic paper EP is an electronic data (ID data) stored in the memory 6 by communicating with a device having an external communication function (adjacent electronic paper, recognition device, management device, etc. described later) through the communication unit 5. Etc.) and these electronic data can be held in the memory 6.
These functional units 2 to 7 are selectively provided in the processing unit 3 according to a necessary configuration according to the use of the optical writing type electronic paper EP, and further, necessary functional units are provided. When applied to the embodiment, the sensor 1 is provided to detect other adjacent electronic paper.

For example, the optical writable electronic paper EP displays image information on the liquid crystal panel 25 as shown in FIG. 13, and the optical writable electronic paper EP is superimposed on the liquid crystal panel 25 while applying a voltage to the electrode 4 from an external power source. By irradiating light, the image information displayed on the liquid crystal panel 25 can be transferred to the display unit 2 and displayed and held.
That is, the optical writable electronic paper EP transfers a projected document image to the display unit 2 by applying a voltage to the electrode 4 and holds the document image in a display state even after the voltage applied to the electrode 4 is removed. It has the function to continue.

  As shown in FIG. 15 showing the cross-sectional structure of the display unit 2, the optical writable electronic paper EP is composed of an organic photoconductive material layer (organic photoconductive layer) 20 and a liquid crystal display material layer used in a copying machine. (Microencapsulated cholesteric liquid crystal layer) 21 is combined, these layers are sandwiched between a pair of front and back transparent electrodes 22, and this laminate is sandwiched between a pair of front and back transparent substrate films 23. In this configuration, the white display in which the cholesteric liquid crystal layer 21 reflects light and the light is transmitted through the liquid crystal layer 21 and absorbed by the black layer 24 provided between the cholesteric liquid crystal layer 21 and the organic photoconductive layer 20. Black display monochrome image display is possible. Furthermore, since the cholesteric liquid crystal has a characteristic of interference-reflecting color light according to the helical pitch, color display can be realized with a simple structure by forming the cholesteric liquid crystal layer 21 by laminating liquid crystals having different helical pitches. It is also possible.

  Then, as shown in FIG. 14 showing the operation principle of the display unit 2, the optical writing type electronic paper EP displays an image to be transferred to, for example, a light control element panel (light emitting panel) 25 for image writing and displays the display unit 2. When the voltage is applied to the electrode 4, the intensity of light is instantaneously converted to the reflection density and the projection image is held. The image information held in the display unit 2 can be erased by applying an erasing voltage to the electrode 4, and the optical writable electronic paper EP can be reused many times by repeating writing and erasing. Note that the optical writing type electronic paper EP does not perform such an erasing process, but applies the voltage to the electrode 4 as described above to project a new image, whereby the image information held in the display unit 2 is stored. Can be overwritten and can be reused again and again by such overwriting.

  Therefore, the optical writing type electronic paper EP has the property of holding the image information transferred by projecting the image without power in addition to the property of being thin and flexible like paper, so that it is used for a printer or a copying machine. It is a portable display recording medium that can be used like paper and can be reused repeatedly. Furthermore, since the optical writable electronic paper EP can have a communication function, a memory function, a control processing function, a sensing function, and the like, it can be used for a document management process according to the present invention as will be described later.

FIG. 16A shows the self-writing electronic paper EP as viewed from the front, and FIG. 16B shows the self-writing electronic paper EP as viewed from the side. The illustrated electronic paper EP includes a display unit 12 that displays and holds document images and a processing unit 13 that controls communication and various processes according to the present invention. FIG. The various functional parts are also shown.
The self-writing type electronic paper EP, like the optical writing type electronic paper EP, is a flexible thin display device having a size such as, for example, A4 size paper, and is processed into a piece of the display unit 12 occupying a large area. A portion 13 is provided. Similar to the optical writing type electronic paper EP, the size of the display unit 12 is set according to the application, and the display unit 12 and the processing unit 13 are detachable as will be described later. You can also.

The processing unit 13 includes a driver 14 for driving the display unit 12, a communication unit 15 for communicating data with the outside wirelessly, a memory 16 for holding electronic data in a readable and writable manner, and a processor for performing various processes according to the present invention. 17, a battery 18 that supplies driving power for the communication unit 15, the processor 17, and the like, and an operation unit 19 such as a button that receives a user operation input such as an instruction for image display.
The self-writing type electronic paper EP is an electronic data (ID data) stored in the memory 16 by communicating with an apparatus having an external communication function (an adjacent electronic paper, a recognition apparatus, a management apparatus, etc., which will be described later) through the communication unit 15. Etc.), and the electronic data can be held in the memory 16.
These functional units 12 to 19 are selectively provided in the processing unit 13 according to a necessary configuration according to the use of the self-writing type electronic paper EP, and further, necessary functional units are provided. When applied to the embodiment, the sensor 11 is provided to detect other adjacent electronic paper.

Further, unlike the optical writing type electronic paper EP, the self-writing type electronic paper EP allows the driver 14 to write a document image on the display unit 12 based on the document data held in the memory 16. Even when the power is removed, the display unit 12 has a function of continuously holding the image information in the display state.
As shown in FIG. 18 showing the cross-sectional structure of the display unit 12, the self-writing type electronic paper EP has fine colored particles (white particles 31 and black particles 32 in the illustrated example) used as toner in the copying machine. Is sealed between a pair of front and back electrodes 33 whose surface side is transparent, and is sandwiched between a pair of front and back film substrates 34 whose surface side is transparent. An air layer is formed between the electrode layers 33 so that the colored particles 31 and 32 can freely move, and the matrix-like electrode layer 33 is provided with an insulating layer 35 that prevents contact with the colored particles 31 and 32. It has been. Note that a color display can be realized with a simple structure by using a color filter.

  The self-writing type electronic paper EP is in a state in which no voltage is applied to the electrode 33 as shown in FIG. 17 showing the operation principle of the display unit 12 (however, the electrode 33 is charged to the polarity at the previous driving). ), The negatively charged white particles 31 accumulate on the back side, while the positively charged black particles 32 accumulate on the front side. When the display unit 12 is viewed from the front side, the display unit 12 is observed. Becomes a black state. And if the electrode polarity of the required part of the matrix according to the image information displayed by operating the driver 14 based on the data stored in the memory 16 is reversed, the positional relationship between the white particles 31 and the black particles 32 is switched. Thus, a document image based on the contrast between the white particles 31 and the black particles 32 is displayed on the display unit 12. In addition, by operating the driver 14 based on different data, the image information displayed on the display unit 12 can be switched depending on the contrast between the white particles 31 and the black particles 32 and can be reused many times.

Accordingly, the self-writing type electronic paper EP has the property of holding the image information displayed on the display unit 12 with no power supply in addition to the property of being thin and flexible like paper, so that it can be used like a paper. It is a possible display recording medium. Furthermore, since the self-writing electronic paper EP of this example can be provided with a communication function, a memory function, a control processing function, a sensing function, etc., it can be used for a document management process according to the present invention as will be described later.
In order to display and hold a document image on the self-writing type electronic paper EP, document data is transmitted from an external writing device and received by the communication unit 15, and the document image is written on the display unit 12 by the driver 14.

Here, regardless of the optical writing type or self-writing type, as shown in FIG. 19, the processing unit 3 (13) such as the communication unit 5 (15), the processor 7 (17), the memory 6 (16), or the like.

In the case of such a processing apparatus 40, the battery provided in the electronic paper may be a capacitor that holds an electromotive force from an external apparatus.

In addition, the present invention can be applied to electronic papers other than formats such as self-writing type electronic paper and optical writing type electronic paper. For example, the electronic paper can be loaded into an external rewriting device and the display unit can be self-writing type. The image information may be written electronically. That is, the self-writing electronic paper is an example of an electronic paper that does not require an external image writing device, and the optical writing electronic paper is an example of an electronic paper that requires an external image writing device. .
In addition, as the display unit 2 (12) of the electronic paper EP, a liquid crystal having a memory property represented by a ferroelectric liquid crystal, an electrophoretic method in which charged particles are moved to switch a display, and charged particles are rotated. Alternatively, a particle rotation method for switching the display, a magnetophoresis method for switching the display by moving particles by magnetism, a thin battery-driven thin liquid crystal or an EL element may be used.

Next, an embodiment of the present invention using electronic paper EP as a display medium will be described.
In the present invention, since the display unit only needs to have a function of displaying and holding a document image in a non-powered state, the electronic paper EP is not limited to the optical writing type or the self writing type.
Further, as will be apparent from the following embodiments, the functional units included in the processing unit 3 (13) are selected according to the system configuration, and the processing unit 3 (13) is integrated with the display unit 2 (12). It is optional whether it is provided or detachably provided.

  In the following embodiment, a document ID that is uniquely set in advance in association with document data is used as data for identifying a document displayed and held on each electronic paper EP. One document can be displayed and held without duplication, and a document ID of these documents and a medium ID uniquely set in advance on each electronic paper can be used.

In the document management system shown in FIG. 1, the electronic paper EP detects another adjacent electronic paper EP, acquires the document ID displayed and held from the other electronic paper EP, and the acquired document ID and It has a function of managing (ID table) the document ID of the document that is displayed and held in association with the adjacent positional relationship. Then, the management apparatus acquires the document ID associated with the adjacent positional relationship managed by each electronic paper EP, integrates them, and associates the document ID with the adjacent relationship for all the electronic papers connected by the adjacent relationship. Add and manage (relation table).
In the electronic paper EP shown in FIG. 1, the device 40 constituting the processing unit is provided in an ID tag format.

In order to realize such management processing, the electronic paper EP and the management device 50 have a functional configuration as shown in FIG.
In addition to the display unit 2 (12) that displays and holds a document image in a non-powered state, the electronic paper EP includes a communication sensor unit 41 that detects other adjacent electronic paper EP and acquires a document ID from the electronic paper. An ID holding unit 42 that holds a document ID for identifying original electronic data (document data) of a document image held in the unit 2 (12), and a document ID acquired from other adjacent electronic paper and the self display and hold ID processing unit 43 that performs processing for associating the document ID of the document that is detected with the adjacent positional relationship, ID table 44 that stores the document ID associated with the adjacent positional relationship, and outputs the data stored in the ID table 44 to the outside Output unit 45.

  The communication sensor unit 41 includes the communication unit 5 (15) and the sensor 1 (11), the ID holding unit 42 includes the memory 6 (16), and the ID processing unit 43 includes the processor 7 (17). The ID table 44 is configured by the memory 6 (16), and the output unit 45 is configured by separately providing the communication unit 5 (15) or the output interface.

Here, by outputting the data of the ID table 44 from the output unit 45 to the output device 60 (for example, a personal computer) that holds the original document data 61, the data processing means 65 in the output device 60 is moved to the adjacent position. Document data can be processed based on the document ID associated with the relationship. For example, a plurality of document images can be displayed on the display screen 62 in a layout reflecting the adjacent relationship of a plurality of electronic papers, or a plurality of document images can be displayed. Document data can be filed and linked to reflect the adjacency relationship of electronic paper.
The data processing based on the document ID is based on a positional relationship with another electronic paper directly adjacent to a certain electronic paper, and the position of the entire electronic paper connected by the adjacent relationship. The process based on the relationship is performed based on the relationship data.

When a plurality of electronic papers EP are arranged on a plane, the communication sensor unit 41 is, for example, a device having directivity at the four corners and sides of the electronic paper EP as shown in FIG. Provided to detect other electronic paper EP adjacent in the same position plane in the up / down / left / right and diagonal directions, and to exchange document IDs by wireless communication in a very short distance within the directly adjacent range. To do.

As described above, the communication ID 41 is contact-connected to the communication sensor unit 41 of another electronic paper stacked above or below, and the document ID is exchanged by contact communication.

The management apparatus 50 integrates document IDs associated with adjacent positional relationships acquired from a plurality of electronic papers EP into an input unit 51 that acquires document IDs associated with the adjacent positional relationships from the electronic paper EP, and forms relation data. A relation processing unit 52, a relation table 53 that holds relation data, and an output unit 54 that outputs the data held in the relation data table 53 to the output device 60 are provided.
From one electronic paper EP, a document ID associated with the positional relationship with another electronic paper directly adjacent to the electronic paper is input, but the relationship processing unit 52 proceeds with the adjacent relationship between these electronic papers. Thus, the relationship data in which each document ID is associated with the positional relationship of all the electronic papers connected by the adjacent relationship is created.

  Therefore, by outputting the data of the related data table 53 from the output unit 54 to the output device 60 that holds the original document data 61, the data processing means 65 in the output device 60 is connected to all adjacent electronic papers. The document data can be processed based on the document ID associated with the adjacent positional relationship, for example, a plurality of document images can be displayed on the display screen 62 in a layout reflecting the adjacent relationship of the plurality of electronic papers, Alternatively, filing or linking that reflects the adjacency relationship between a plurality of electronic papers can be applied to the document data.

In the example shown in FIG. 1, four electronic papers EP (A to D) that display and hold different document images are used, and when the document images are written, the original electronic data of each document image is identified. The ID (A to D) is input to each electronic paper EP (A to D) and held in the ID holding unit 42.

To be recorded in the ID table 44.
For example, another electronic paper (B) is arranged adjacent to the left, another electronic paper (A) is arranged adjacent to the upper left, and another electronic paper (D) is arranged adjacent to the right (C) ) Acquires document IDs (B), (A), and (D) from these other adjacent electronic papers, and the ID processing unit 44, as shown in FIG. 1, position = left: document ID = B, The document ID is recorded in the ID table 44 in association with the adjacent positional relationship as position = upper left: document ID = A, position = right: document ID = D.
In the illustrated ID table 44, medium IDs are also described and managed.

As described above, the data of the ID table 44 managed by each electronic paper EP is input from the input unit 51 to the management device 50, integrated by the relationship processing unit 52, and stored and managed in the relationship table 53.
In the example illustrated in FIG. 1, the ID table data 44 acquired from the electronic paper (B) and the ID table data 44 acquired from the electronic paper (C) from a certain electronic paper (for example, the electronic paper (A)) Are integrated, and position = lower left: document ID = B, position = lower right: document ID = C, position = with respect to a certain electronic paper (for example, electronic paper (A): document ID = A). Bottom right: Document ID = D, and document ID is recorded in the relationship data table 53 in association with the adjacent positional relationship between the four electronic papers.

  The relational data 53 is obtained by associating document IDs for identifying document images (original electronic data) displayed and held by all the electronic papers that are directly or indirectly adjacent to each other in the adjacent positional relationship. When the output device 60 displays the document image from the original document data on the screen 62 based on the relationship data 53, the document image 64 on the screen is displayed in the arrangement position relationship of the electronic paper EP.

The document ID is associated based on the electronic paper EP.
FIG. 5 shows still another embodiment according to the present invention. This embodiment is arranged on a plane using the recognition device 70 having a function corresponding to the communication sensor unit 41 described above. Document IDs are associated based on a plurality of electronic papers EP.

  In these examples, the recognition device 70 detects the adjacency relationship of the electronic paper EP and acquires the document ID from the electronic paper EP, and the management device 50 generates the relationship data 53 based on the adjacency relationship and the document data. Therefore, the ID processing unit 43 and the ID table 44 can be omitted in the electronic paper EP.

The system configuration shown in FIGS. 4 and 5 is substantially the same as the system configuration shown in FIG. 1, but the recognition device 70 having the functional configuration shown in FIG. Do.

That is, the arrangement position relationship of each electronic paper EP on the plane H is detected, and each arrangement position is output to the management apparatus 50 in association with the document ID.

As shown in FIG. 8, the management device 50 of this example includes an input unit 51 that acquires data from the recognition device 70, and a classification template data storage unit that holds patterns (classification templates) of regions partitioned on the plane H. 82, a classification processing unit 83 that creates relational data in which a document ID is associated with a region by referring to a pattern of a region held by the classification model data storage unit 82 for data acquired from the recognition device 70; A classification storage unit 84 to be held and a template input unit 85 to receive an input for updating a pattern of an area held by the classification template data storage unit 82 are provided.
In the example illustrated in FIG. 8, the output device 60 is provided integrally with the management device 50. In addition, the management device is provided with a printer P that displays and holds document images on the electronic papers EP1 to EP18 based on the document data 61 and outputs them.

In the example shown in FIG. 7, 18 electronic papers EP (EP1 to EP18) that display and hold different document images are used. As in the above example, the document ID for identifying the original electronic data of each document image is used. Is input to each electronic paper and held in the ID holding unit 42.
Then, when these electronic papers are arranged in areas (R1 to R5) on the plane H and a start button (not shown) of the recognition device 70 is operated, the communication sensor unit 71 of the recognition device 70 causes these electronic papers EP1 to EP18. Is detected, the document ID is acquired from the electronic paper, and the positional information of each electronic paper EP1 to EP18 and the document ID are associated with each other and input to the management apparatus 50.

The management device 50 determines in which of the regions (R1 to R5) the position information of the respective electronic papers EP1 to EP18 acquired from the recognition device 70, and performs a classification process for associating the document ID with the corresponding region. Go to generate relationship data.
In the example shown in FIG. 1, for example, four document IDs of documents displayed and held by the electronic papers EP1, EP15, EP5, and EP13 are associated with the region R1, and the documents held by the electronic papers EP11 and EP2 are displayed. Relationship data such as associating two document IDs with the region R2 is generated. That is, the document ID is classified as an area unit lump.

Therefore, various processes such as screen display and filing can be performed on the document data by the output device 60 based on the document IDs classified for each region in this way.
Here, the processing described in the other embodiments can be applied to this example to detect and use the adjacent positional relationship of each electronic paper in the region. It is possible to obtain relationship data that is classified as a block of region units and that also associates adjacent relationships in the region.

The area pattern held in the classification model data storage unit 82 serves as a reference for the classification. For example, the area pattern can be input from the model input unit or prepared in advance and selected by the user each time. Various patterns as shown in FIGS. 9 to 11 can be used.
The pattern shown in FIG. 9 is obtained by dividing a plurality of regions (R1 to R4) vertically, and is suitable for business planning work, video story organizing work, etc. that are performed while arranging a large number of electronic papers (documents) vertically. It is a thing.

The pattern shown in FIG. 10 is obtained by dividing a plurality of regions (R1 to R4) horizontally, and the purpose of creating a balanced score card and system thinking performed while arranging a large number of electronic papers (documents) in the horizontal direction. It is suitable for deployment work.
The pattern shown in FIG. 11 is obtained by dividing a plurality of regions (R1 to R4) in a grid pattern, and is suitable for a market analysis work or a four-quadrant analysis work performed while grouping a large number of electronic papers (documents). It is.
