Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention displays multimedia data laid out on a sheet-like card for each card, and links between cards, between cards and multimedia data, or between multimedia data. A hypermedia system that displays those information structures as a map including a card icon that is a reduced image of each card, a map display method in the system, a dedicated screen display method for link editing, and card icon selection / Regarding the cancellation method.

[0002]

2. Description of the Related Art In recent years, in a personal computer or the like, multimedia data laid out on a sheet-like card is displayed for each card, and related to each other between cards, between cards and multimedia data, or between multimedia data (link). ) Has been developed, and a system that can trace data along this link has been developed.

In such a system, when a user views the result of layout editing or link editing of multimedia data on a card, in the information space constructed like a network, where is the current position and in which direction? It was pointed out that there was a problem of not knowing if it was heading.

Therefore, in order to solve these problems, Takahiro Kii et al., "Correspondence to large-scale data in hypermedia authoring tool-data management-, 44th National Convention of Information Processing Society of Japan" and Japanese Patent Application No. 4 -305122
As described in No. 6, a system (hypermedia system) for displaying an information structure on a screen as a map has been developed. Here, the hypermedia system described in the former is called a first hypermedia system, and the hypermedia system described in the latter is called a second hypermedia system.

The above-mentioned first hypermedia system has a map showing the relationship (link) between cards or multimedia data. The map is represented by using icons (reduced image icons) obtained by reducing the image of each card and lines indicating the link relationship. The link relationship of this map is expressed in units of cards and multimedia data (hereinafter referred to as card parts),
Editing such as relinking links can be done on the map. For that purpose, it is necessary to clearly identify the card component which is the start point or the end point of the link on the card on the screen, and therefore the card icon is displayed to some extent large.

On the other hand, in the second hypermedia system, the icon of the reduced image of each card (card icon) is used, the card icon is laid out at an arbitrary position on the two-dimensional plane, and the link relationship between the cards is determined. By expressing it as a line between the icons, the card icons are arranged and displayed in a network form.

As described above, the second hypermedia system also has a map showing the relationship (link) between cards or multimedia data, like the first hypermedia system, but the link relationship is the first hypermedia system. Different from the media system, it is represented by card.
As such, the icon need not be as large as in the first hypermedia system.

[0008]

As described above, conventionally, as a typical hypermedia system having a map showing a relation (link) between cards or multimedia data, a map link relation is a card-card relation. First expressed in parts (multimedia data)
And the second hypermedia system in which the link relationship is expressed in card units.

In the first hypermedia system described above, since the link relationship is expressed in units of cards and card parts, the links can be edited on the map.
The icon representing the card (card icon that is a reduced image of the card) had to be enlarged to some extent.
However, if the card icon becomes large, the number of cards that can be viewed will decrease, and if the number of created cards will increase, for example, when switching links, the icon of the replacement source and the replacement destination will be changed. There is a problem that the icon cannot be displayed in a list, and this reassignment operation becomes difficult.

On the other hand, in the second hypermedia system, since the link relation is expressed in card units,
Compared to the first hypermedia system, the card icons do not have to be that large, so the number of card icons that can be viewed is increased, making it easier to grasp the overall image of the link relationship between cards, which is the original function of the map. It becomes easy to understand. However, if the card icon is small, there are problems that it is difficult to identify the contents of the card, the link cannot be confirmed for each card component on the map, and the link cannot be edited on the map.

In this type of hypermedia system, cards can be edited (deleted, etc.) on the map. Among them, card deletion is the one to pay particular attention to. For example, if you select a card and execute card deletion, not only that card, but also links that come from that card or parts on that card, and links that come in to that card or parts on that card It will be deleted at the same time. Therefore, when deleting a card, it is necessary to consider the link status, and a function that helps to do so is required.

Further, in this type of hypermedia system, the user can freely cut out any card displayed on the map and use the card. As a usage method, for example, it is possible to select some cards from many cards on the map and use the cards to create a new story. However, when the number of cards becomes very large, it is not easy to choose which card to discard and which to discard. Therefore, a clue to determine which card to select and which to discard and a function to support card selection are also required.

The present invention has been made in consideration of the above circumstances, and its purpose is to make each icon on a map small to a certain extent so as to be selected and designated by the user while maintaining the listability of the entire map as much as possible. To provide a hypermedia system and a map display method that can identify each card and confirm the layout by enlarging the card icon on the map for all of the necessary card icons on the map. It is in.

Another object of the present invention is to link a magnified card icon of a card icon selected by a user on a map and a link reflecting a link relationship between cards, between a card and multimedia data, or between multimedia data. By displaying on a dedicated screen for confirmation and link editing, the link between each card and multimedia data (card parts) corresponding to the card icon selected by the user can be confirmed and It is an object of the present invention to provide a hypermedia system and a dedicated screen display method capable of editing links on a dedicated screen.

Still another object of the present invention is to display each card icon of all cards having a link relationship with the card to be deleted selected by the user at the time of card deletion so as to be distinguishable from other card icons having no link relationship. By displaying in the form, which card (or card parts on the card) will be displayed when the card selected by the user is deleted.
It is an object of the present invention to provide a hypermedia system and a map display method when a card is deleted so that the user can check in advance whether the link between and will be broken.

Still another object of the present invention is to provide a hypermedia system and a card icon selecting / releasing method capable of supporting efficient card extraction by selecting a card icon on a map.

[0017]

The structure according to the first aspect of the present invention has a card icon which is a reduced image of each card, between cards, between cards and card components (multimedia data), or between cards. Select and specify one or more arbitrary card icons to be magnified on the map expressed by the line connecting the corresponding card icons for expressing all the link relationships between parts as the link relationship between cards. And a map display control means for switching and displaying the enlarged card icon instead of the selected and designated card icon.

In such a configuration, when it is necessary for the user to identify the desired card and confirm the layout of the card components, if all the card icons of the required card are selected, the selected card icon is replaced. The enlarged card icon is displayed, so the size of each card icon on the map is reduced to a certain extent by a map that shows the link relationship on a card-by-card basis, and the list of the entire map is maintained as much as possible while necessary. For the cards required for the above, card identification and layout of card parts can be confirmed on the map.

The configuration according to the second aspect of the present invention is a selection designating means for selectively designating one or more arbitrary card icons to be a target of link confirmation or link editing on the map. This is a line that represents the link relationship between the expanded card icon for link editing, which is the expanded card icon of the selected and specified card icon, and between cards, between cards and card parts, or between card parts, and between the corresponding expanded card icons. And a dedicated screen display control means for displaying a line connecting the enlarged card icon and the image of the card component or the image of the card component on a dedicated screen different from the display screen of the map. To do.

In such a configuration, when the user selects a card icon on the map, the enlarged card icon (enlarged card icon for link editing) of the card icon, between the enlarged card icons, and between the enlarged card icon and the card A line connecting images of parts or images of card parts is displayed on a dedicated screen different from the map display screen. Here, the line displayed on the dedicated screen is
It reflects links between cards, between cards and card parts, or between card parts.

Therefore, on the map display screen, the link relationship is expressed for each card, thereby making use of the original characteristic of the map that lists the link relationships between the cards.
For the card icon (corresponding card) selected by the user on the map, the link between cards and card parts can be confirmed and the links can be edited according to the link relationship expressed in units of cards and card parts on the dedicated screen. You will be able to do it. Moreover, as long as the link is edited on the dedicated screen, only the enlarged card icon of the card selected by the user for which the link is to be edited is displayed on that screen. The problem that the replacement source icon and the replacement destination icon cannot be listed at the time of link replacement, as in a system capable of performing the above (first hypermedia system), does not occur.

The configuration according to the third aspect of the present invention is characterized by combining the configurations according to the first and second aspects. In such a configuration, a map that represents the link relationship for each card is used to check the link relationship between the cards, and the card icon selected by the user on the map is enlarged to check the contents of each card. An enlarged card icon display function for switching to a card icon is used, and a dedicated screen is used for editing a link, so that the link relationship is expressed for each card and card component unit only for the card selected by the user.

Therefore, it is possible to check the link relationship and edit the link more finely while utilizing the original characteristic of the map that lists the link relationships between the cards. A configuration according to a fourth aspect of the present invention is to provide a selection designating means for selectively designating an arbitrary card icon to be deleted on a map, and a link to a card represented by the selected deletion-targeted card icon. A search means for searching all related cards and a map display control means for changing the display form of the card icon of the searched card to a display form different from other icons not having a link relationship Is characterized by.

In such a configuration, the display mode (for example, display color) is changed so that the card having the link relationship with the card can be distinguished from the other cards having no link relationship when the user designates the card to be deleted.

Therefore, the user deletes the card selected by himself / herself in advance on the map to determine which card or card component or link from which card or card component will be cut. You can check. Therefore, an erroneous operation by the user can be prevented.

The configuration according to the fifth aspect of the present invention is a selection designating means for selectively designating a card icon to be a root icon of a group of card icons to be collectively selected on a map, and this selection designation. Search means to search for cards that can be followed one by one from the card with the specified card icon to the link destination, and the card icons of all the searched cards together with the selected and specified card icon at once And a selection means.

The configuration according to the sixth aspect of the present invention is the same as the configuration according to the fifth aspect, except that one of the card icons in the selected state is selected.
Selection designation means (second selection designation means) for selectively designating one as the root icon of the card icon group to be released from the selected state, and from the card of the selected and designated card icon to the link destination one after another. A search means for searching for a card that can be followed (second search means) and the card icons of all the searched cards are selected as the root icon of the card icon group to be released and the selected card icon is selected. And a selection canceling unit for canceling the selection.

In such a configuration, all the card icons of the cards whose links can be traced from the card of the user-specified card icon are in the selected state together with the user-specified card icon, for example, a color different from that of other unselected cards. Is displayed.

When a user selects and designates an arbitrary card icon from the card icon group selected by the card icon batch selection function (card cutout support function), the designated card icon The deselection function that deselects the card icon of the card whose link can be followed from the card is activated together with the designated card icon.

By using the above-mentioned card icon batch selection function (card cutout support function), it becomes possible to cut out all the cards to be used collectively by using the link originally provided on the map as a clue. Originally, the links on the map were put under the intention of the card creator. Therefore, the link relationship is important as a clue for a person different from the creator to create a new story based on the map. Therefore,
The above-mentioned collective selection function, that is, the function that the linked card extending from the card designated by the user is in the selected state is very useful as a clue for card selection. In addition, especially when cutting out cards with a link, it is possible to select all the cards related to the link all at once. Based on the link relation, the selection canceling function that can collectively cancel the selection of parts can provide the user with further excellent operability.

Next, the map display by the map display control unit 118 will be described. FIG. 5 shows the map display control unit 118.
An example of a map displayed on the display screen of the display device 120 by is shown.

FIG. 5 shows an example of a map showing a link relationship for each card, and the card icon 51i
The link relation is represented by the link 52 connected between (i = a, b ...). Here, the directionality of the link 52 is expressed using an arrow.

The card icon 51i in FIG. 5 has a card image created by the card display control unit 117 based on the card layout information (card data inside) managed by the card layout management unit 112 (see FIG. 2). ) Is used to obtain image data. Therefore, the user can know the outline of the contents of the corresponding card by each card icon 51i.

The map layout information (map layout information) shown in FIG. 5 is managed by the map layout management unit 114 in the form shown in FIG. 6, for example. That is, the map layout information is the map list 61.
Is managed by an array called "," and the array has a pointer 61a to the map data 62. This map data 62
Exists for the number of maps managed by the map list 61. The map list 61 may have a list structure instead of an array.

The map data 62 indicates the actual (rectangular) display area of the corresponding map (map # 1 in FIG. 6) on the display device 120 (for example, the x, y coordinates of the upper left corner of the area,
Display area information 62a indicated by width w and height h), a pointer 62b to a list (layout list of card icon layout information) 63 of layout information of each card icon on the map, and layout information of each link on the map. And a pointer 62c to a list (link layout information list) 64 of.

Card icon layout information list 63
Is a pointer 6 to (the card data of) the card for each card on the corresponding map (map # 1 in FIG. 6).
3a, a reduced card icon (predetermined size) that is a reduced image of the card, a pointer 63b to an enlarged card icon (predetermined size) that is an enlarged image of the reduced card icon, and the center of both icons. It has a position coordinate 63c. Here, it is assumed that the center positions of both icons are the same. In the normal map display shown in FIG. 5, a reduced card icon is used as the card icon 51i.

The link layout information list 64 has a pointer 64a to a link source card, a pointer 64b to a link destination card, and a link source card for links linked between cards on the corresponding maps. 64c of links (including links between objects on the cards) stretched between the card and the link destination card,
It has the start point and end point coordinates 64d of the link.

When the map display is selected on the menu screen in the card display state as shown in FIG. 2, for example, the map display control section 118 receives the map layout management section 11
Start 4. In this case, the map layout management unit 11
Reference numeral 4 denotes map data (62) of a map including a card currently being displayed, a card icon layout information list (63), and a link layout information list (from the map layout information managed by itself, as shown in FIG. 6
4) is extracted and passed to the map display control unit 118.

The map display control unit 118 creates a map image as shown in FIG. 5 based on the data passed from the map layout management unit 114 and displays it on the display device 120.
To display.

In the present embodiment, the map display control unit 1
The display device 120 displays a map as shown in FIG.
When the user operates the input device 130 (for example, the mouse) to select an arbitrary card icon 51i (i = a, b ...) While being displayed on the screen, and selects the move card on the menu screen, Selected card icon 51i
Can be moved using the input device 130 (mouse).

The map display control section 118 changes the display state of the map in accordance with the moving operation using the input device 130 for the card icon 51i selected on the screen, and moves the card icon 51i on the screen. At the same time, the position (start point or end point coordinate) of the link between the card icon 51i and another card icon is also changed.

When the map display control unit 118 detects the end of this moving operation by, for example, raising the mouse button, it activates the map layout management unit 114. In this case, the map layout management unit 114 reflects the map display state changed by the map display control unit 118 on the map layout information managed by itself, so that the map layout information list 6 of the corresponding map is displayed.
3 and the contents of the coordinate data of the link layout information list 64 are updated.

Next, expansion of the card icon on the map will be described. Now, in the map display state shown in FIG. 5, it is assumed that the user selects, for example, the card icon (reduced card icon) 51b by operating the input device 130 and selects enlargement of the card icon on the menu screen.

Then, the map display control unit 118 activates the map layout management unit 114. In this case, the map layout management unit 114 selects the user (corresponding to the card icon 51b from the card icon layout information list (63) for the currently displayed map among the map layout information managed by itself. ) Pointer to the enlarged card icon for the card (63
Extract b). The file name of the file storing the image data of the corresponding enlarged card icon is stored in the primitive data management unit 111 pointed to by this pointer. This file is also stored in the primitive data management unit 111. Therefore, based on the file name pointed to by this pointer, the map layout management unit 114 takes out the data of the corresponding file, that is, the image data of the enlarged card icon for the card designated by the user, from the primitive data management unit 111 and displays the map. It is passed to the control unit 118. It should be noted that the pointer may directly indicate the storage location of the image data of the corresponding enlarged card icon.

Upon receiving this image data, the map display control unit 118 replaces the image data with the reduced card icon 51b designated by the user shown in FIG.
The enlarged card icon 71 is displayed as shown in FIG. Here, the display position of the enlarged card icon 71 is set so that the center thereof coincides with the center of the display position of the original reduced card icon 51b.

In order to prevent the enlarged card icon 71 from overlapping with other card icons when the enlarged card icon 71 is displayed, a grid is set when a normal icon (reduced card icon) is laid out on the map. By doing so, the layout may be performed at a position apart from one icon by a certain distance. In addition, the display of the enlarged card icon can be performed simultaneously for a plurality of icons.

Next, card deletion will be described. In this embodiment, by deleting the card icon on the map by an editing operation, the card corresponding to the icon can be deleted.

Now, as shown in FIG. 8, a card icon 81,
Also, by deleting the card icon 81 by an editing operation on the map including the card icons 82 to 86 of the cards having a link relationship with the card corresponding to the card icon 81, it is desired to delete the card corresponding to the icon 81. And

In this case, the user operates the input device 130 in the map display state shown in FIG. 8, selects the card icon 81, and selects the deletion of the card icon on the menu screen. This means that the map display control unit 118
Is notified to the map layout management unit 114.

Then, the map layout management unit 114
Is the card icon 81 selected (designated to be deleted) by the user based on the map layout information as shown in FIG.
The pointer (32a) to (the card data 32 of) the card corresponding to is acquired. Next, the map layout management unit 1
Reference numeral 14 denotes a card (pointer to) having a link relationship with the card indicated by the acquired pointer (32a) (that is, the card to be deleted), as shown in FIG. It is extracted from the link data (41) using the link management unit 113.

The map layout management unit 114 determines the card icon of the extracted card, that is, (the display position of) the card icon of the card having a link relationship with the card to be deleted, based on the map layout information shown in FIG. To get to. In the example of the map display of FIG. 8, the card icons 82 to 85 of the card whose link source is the card corresponding to the card icon 81 selected (designated to be deleted) by the user.
And the card icons 83 and 86 of the card to which the card corresponding to the card icon 81 is linked.

The map display control unit 118 differs from the other icons in the card icons 82 to 86 of the card having the link relationship with the card corresponding to the deletion target card icon 81, which is obtained by the map layout management unit 114. In addition to being displayed in the first color, the deletion target card icon 81 is also displayed in another second color. In FIG. 8, the difference in display color is represented by the presence or absence of hatching and the type of hatching.

When the card corresponding to the card icon 81 selected by the user is deleted by performing such display control, the card and the card icons 82 to 86 displayed in the first color are deleted. The user can be warned in advance that all links with the card will also be deleted. Instead of changing the color, the gradation may be changed or blink display may be performed. This makes it possible to apply the display device 120 even if it is a monochrome display. In short, the card (the card icon of) that has a link relationship,
The display form may be changed so that the user can identify (the card icon of) another card on the map.

In the above display control, the map display control unit 118 indicates that the deletion target card icon 81 is the display device 1.
The screen is scrolled vertically and horizontally so that it is displayed in the center of the display screen of 20. As a result, it is possible to display a list of card icons 82 to 86 (of cards) having a link relationship. In addition, even by this screen scroll,
If all the card icons (of cards) having a link relationship cannot be displayed, the map display control unit 118
In addition to the card icon currently displayed in the first color, there is an icon with a link relationship,
For example, a warning is displayed by displaying a message to that effect.

The user confirms the link deletion warning by the display control of the map display control unit 118 described above, and if there is no problem, deletes the delete target card icon 81 (corresponding card) selected by the user. Select the command (OK to delete card icon) that instructs execution.

Next, link editing such as link replacement will be described. First, when relinking is desired, the user selects the link edit mode (use mode of the link edit dedicated screen) on the menu screen in the map display state. Next, the user uses the input device 130 to perform an operation for selecting, from the map, the card icon that is the link replacement source and the card icon that is the link replacement destination on the map.

Objects laid out above (for the data managed by the primitive data management unit 111)
A pointer 102a to the card, area information 103b indicating the area in which the object should be displayed, and a pointer 103c to the link data 103 indicating a link between the object and another object, as a group. Have as many arrays as the number of objects laid out above.

The link data 103 holds and manages the link data displayed on the dedicated screen.
The link data 103 has a pointer 103a to the link source object of the target link, a pointer 103b to the link destination object, and the start point and end point coordinates 103c of the link.

Now, the dedicated screen display control unit 119 is shown in FIG.
When the dedicated screen layout information shown in 0 is created by the dedicated screen layout management unit 115, the display device 1
The dedicated screen (window) as shown in FIG. 9 is opened on the screen 20 while leaving the map display screen (window), for example.

Then, the dedicated screen display control unit 119, according to the layout information created by the dedicated screen layout management unit 115, the link editing enlarged card icon (which is a reduced image) of the card selected by the user for the link editing. Display the link corresponding to (link relationship for each card or object) on the dedicated screen. Here, since the enlarged card icons for link editing are displayed for all the cards selected by the user, unlike the case of the map display using the reduced card icons as shown in FIG. 5, that is, the object (card part) Unlike the case of the map display that is displayed as the link between the cards having the object, the link between
As described above, a display mode in which the links between objects or the links between objects and cards are correctly reflected is realized.

As described above, the display coordinates of the enlarged card icon for link editing displayed according to the dedicated screen layout information on the dedicated screen (that is, the enlarged card icon shown in the dedicated screen card layout information list 101 in the dedicated screen layout information). The display coordinates on the dedicated screen of (1) are automatically determined according to the number of icons as shown in FIGS. For example, when there is one icon, it is at the screen center position as shown in FIG. 11A, and when there are two icons, it is on the left side and right side of the screen as shown in FIG. Icon on the left). When the number of icons is three or more, the icons are arranged in the order of registration as shown in FIGS. 11C to 11E, and are arranged from left to right on the screen and from top to bottom on the screen. To be done.

The link between the position of the enlarged card icon for link editing and the card icon (or the object on the card icon) displayed in this way is determined by the input device 1
It can be edited by a user operation using 30.
For example, when the user uses the input device 130 to change the link on the dedicated screen as shown in FIG. 9,
The dedicated screen display control unit 119 updates the display content on the dedicated screen in response to the replacement operation. The dedicated screen layout management unit 115 also manages the object list 102 managed by itself so as to reflect the updated display content.
And the contents of the link data 103 are updated.

When the link replacement operation by the user is completed and executed, the map layout management unit 114
FIG. 1 managed by the dedicated screen layout management unit 115
Based on the dedicated screen layout information (updated dedicated screen layout information) as shown in 0, the contents of the link layout information list 64 in the map layout information as shown in FIG. rewrite. Similarly, the link management unit 113 has a dedicated screen layout management unit 115.
Based on the updated dedicated screen layout information managed by the above, the link data 41 managed by itself as shown in FIG. 4 is rewritten. Map display control unit 118
When the map layout management unit 114 updates the contents of the map layout information (link layout information list 64 therein), the updated contents are reflected in the display contents of the map.

As described above, by using the link editing dedicated screen as shown in FIG.
You can check the link relationship for each card and card component and edit the link on the screen.

By the way, as the number of cards on the map increases, there is a demand for cutting out not all of these cards but only some of them to use them for presentations, for example. In such a case, clues for deciding which card to discard and a function for supporting the card cutting operation will be required.

Therefore, in the system of the present embodiment, as such a support function, a function of collectively selecting a plurality of card icons by following a link and a function of partially deselecting the card icons collectively selected by the function have. The batch selection function and the partial selection cancellation function will be described below.

Now, it is assumed that the user selects the collective selection command on the menu screen and selects, for example, the card icon 51a on the map shown in FIG. 5 by using the mouse of the input device 130. This means that the map display control unit 11
8 to the map layout management unit 114.

Then, the map layout management unit 114
Is a pointer (32a) to (the card data 32 of) the card corresponding to the card icon 51a selected by the user based on the map layout information as shown in FIG.
To get.

The map layout management unit 114 manages the card (pointer to) the link destination card of the card indicated by the acquired pointer (32a) (that is, the card to be directly selected) by the link management unit 113. Figure 4
It is extracted from the link data (41) as shown in (1) using the link management unit 113.

Next, the map layout management unit 114 extracts a card (pointer to) the link destination card for the extracted link destination card using the link management unit 113 in the same manner as described above.

In this way, the map layout management unit 1
14 is a card (pointer to) that can follow links one after another from the card corresponding to the card icon (51a) selected by the user (the card is the root card).
Get all. The number of steps (the number of levels of depth) for following the link may be designated by the user in advance, and the link may not be followed over the number of steps.

The map display control unit 118 displays the card icon of the card acquired by the map layout management unit 114 and the card icon (51a) selected by the user.
For example, it is displayed in a different color from other icons to indicate that these icons are in the selected state. The map display state at this time is shown in FIG. Note that, in FIG. 12, the card icons in the selected state are hatched.

The above is the collective selection function. Next, the partial selection canceling function will be described. The partial deselection function in this embodiment includes a first deselection function for sequentially deselecting cards (card icons) in the selected state one by one, and a card (card icon) in the selected state. There is a second deselection function that deselects all (card icons of) cards that can follow links one after another when one is selected again.

The first selection canceling function is realized, for example, by pressing the specific key on the keyboard in the input device 130 and selecting the card icon of the card to be deselected.

The second selection canceling function is realized by selecting an arbitrary card icon in the selected state again using the mouse of the input device 130.
In this case, not only the selected card icon (corresponding card), but also the linked card of the card, and the linked card to the linked card, one after another in the same manner as the batch selection described above. By following the link to, you can deselect all the card icons for the linked card.

However, in this selection canceling method, if the link is in a loop, even an unintended card may be selectively deleted. For example, when the card icon 51d is selected in the card icon selection state as shown in FIG. 12, all the currently selected card icons are deselected.

Therefore, in this embodiment, the positional relationship between the top, bottom, left, and right of the card icon on the map is utilized to determine the position shown in FIG.
As shown in, the priority order regarding the deselection of the card icon is set. Here, the higher the card icon on the map and the higher the card icon on the left side of the map, the higher the priority. Therefore, the card icon in the upper left corner has the highest priority, and the card icon in the lower right corner has the lowest priority. Further, even if the icon is located on the right side of a certain card icon, the icon located above the icon has a higher priority.

In this embodiment, when one of the selected card icons is selected under the above priority setting, only the card icon having a lower priority than that icon is deselected. I have to.

As a result, even if the card icon 51d is selected in the card icon selection state as shown in FIG. 12, the card icons 51a to 5a having a higher priority than the card icon 51d are selected.
1c is not deselected.

As described in detail above, according to the present invention, the size of each card icon on the map is reduced to some extent, and the enlarged card icon display function is used while maintaining the listability of the entire map as much as possible. Identification of each card and confirmation of the layout of card parts can be performed on the map for all necessary card icons when necessary.

Further, according to the present invention, all the card icons selected on the map in the link edit mode are enlarged and displayed on the dedicated screen, and the links between the cards and the card parts are also displayed. You can check and edit links between cards and card parts. Moreover, by editing the link on the dedicated screen,
The problem that the replacement source icon and the replacement destination icon cannot be listed at the time of link re-linking, unlike the conventional system that allows editing of links on a map, will not occur.

According to the present invention, the map is used to confirm the links between the cards, the enlarged card icon display function is used to confirm the contents of each card, and the dedicated screen is used to edit the links. As a result, it is possible to perform more detailed link relationship confirmation and link editing while making the most of the map's original feature of listing the link relationships between cards.

Further, according to the present invention, when the card to be deleted is designated, the display form is changed so that the card having a link relationship with the card can be distinguished from other cards.
By executing the deletion of the card selected by the user, the user can confirm in advance which card or card component or link from which card or card component will be broken, and therefore the user Incorrect operation can be prevented.

Further, according to the present invention, when the user selects and specifies a card icon on the map, the card icons which can be successively traced from the specified icon to the link destination are collectively selected together with the specified icon. Further, when the user selects and designates one of the card icons in the selected state, the card icons whose links can be followed from the designated icon can be collectively released from the selected state together with the designated icon. This allows
It is possible to support efficient card extraction by selecting a card icon on the map.
