DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information display device, and more particularly, to an information display device suitable for a case where data to be displayed has a hierarchical structure or a tabular format, and a recording medium recording an information display program. It is about.

[0002]

2. Description of the Related Art In recent years, the amount of data handled by a computer has been increasing, and when the amount of data cannot be accommodated on one screen, the following techniques have conventionally been used.

As a first prior art, there is a scroll system which is widely used as a computer user interface. The scroll method is a method of viewing a part of information through a virtual window (Window) that can move up and down or left and right, and is used in a text editor, a graphic system, and the like.

As a second prior art, a method utilizing three dimensions has been proposed. As a document describing a method using three dimensions, for example, 189 of Proceedings of CHI published in 1991
Robertson, p.
G. FIG. S. And others published a paper “ConeTrees: An
imated 3D Visualizations
of Hierarchical Information
In the technique described in this document, a hierarchical structure is represented by a tree in a three-dimensional space having a node at each vertex of a cone and each child node on the base circle. In this method, even if the image is protruded from the screen in the two-dimensional display by using the depth direction of the three-dimensional space, it can be accommodated in the screen.

As a third prior art, a method utilizing translucency has been proposed. As a document describing a method using this translucency, for example, “I” described on page 1 to page 8 of the Japan Society for Software Science and Technology WISS '93.
nformation Cube: a three-dimensional information visualization technique using translucent display "is known. The technique described in this document proposes a method of expressing a hierarchical structure by using translucent nested cubes.

A fourth prior art is disclosed in Japanese Patent Laid-Open No. 3-257.
A display method described in Japanese Patent Application Laid-Open No. 677 is known. In the technique described in this publication, a display method is described in which the size of a character font is changed according to the distance in a hierarchical structure to improve the display amount on a screen.

[0007]

However, the first to fourth prior arts have a problem that the whole cannot be viewed at once, that is, the listability is poor. For example, in the first conventional technique, a method using scrolling,
There is a problem that it cannot fit on the screen at once. Also, in the second conventional technique, a method using three dimensions, there is a problem that characters in the depth direction are hidden by characters in front and cannot be read. Further, in the third conventional technique, a method using translucency, there is a problem that a portion where characters overlap is complicated and difficult to read. In any case, since the characters are difficult to read, the overall listability is low. Further, the fourth conventional technique, the method of changing the size of the character font, has a problem that when the data amount becomes large, each character becomes too small, and as a result, the listability is also reduced.

[0008] An object of the present invention is to provide an information display device and a recording medium on which an information display program is recorded, which can solve the problems of the prior art and has improved browsability.

[0016]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. There are a total of six embodiments of the present invention, and each of the six embodiments will be described in detail.

(1) First Embodiment First, FIG. 1 is a block diagram showing a configuration according to a first embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG.

Reference numeral 1 denotes an input means for providing a means for the user to input, and the user designates a point of interest through the input means. The input means 1 corresponds to a conventionally used pointing device such as a mouse, a keyboard, or the like.

Reference numeral 4 denotes a data recording unit for recording data to be displayed. The attribute of each data and the connection relationship between the data are recorded.

Reference numeral 2 denotes a folding display control unit for controlling the display by partially folding or opening the data to be displayed like a folding screen. The fold display control unit 2 is composed of two components: a fold area determination unit 6 and an overlap position calculation unit 7. This folding area determination unit 6
Determines the region to be folded and the region to be opened, and the overlap position calculation unit 7 calculates the overlap position of each region based on the current connection position of the point of interest and the data connection.

In the present specification, the term "folding" means that data to be displayed is divided into data to be displayed and data that need not be displayed so as to reduce the display area of the data that does not need to be displayed. The display area of the screen is saved. For example, when the data to be displayed has a hierarchical structure, an area where the user's point of interest is located and an area near the point of interest are set as the data area to be displayed, and the other areas are set as the data areas that need not be displayed. In other words, for data that does not need to be displayed, the display width of the data is reduced, or the hierarchical connection relationship between the data is hidden. Further, for example, when the data to be displayed is in a table format, the display width of the area where the user's point of interest is located and the area in the vicinity thereof is increased, and the display width of the other areas is reduced. In this specification, the term “open” refers to displaying information without conserving the display area and displaying data connection relations clearly, in contrast to folding.

Reference numeral 5 denotes a display unit for performing display based on the determination of the folding area determination unit 6 and the overlap position calculation unit 7.

Here, an operation example of the first embodiment will be described with a specific example. In the following operation example, the area of the point of interest and the area where the point of interest is connected to the child and grandchild are opened,
An example will be described in which the remaining area is folded. However, the example of folding and opening this area is merely an example, and the present invention is not limited to this operation example. In the following operation example, the open area does not overlap with other areas, and the foldable area has a width capable of displaying a character string indicating the content of the foldable area by 1.5 characters, and the remaining part has Will be described with a calculation method that overlaps with another region. This calculation method is also an example, and the present invention is not limited to this operation example.

In the following, a description will be given using an example in which hierarchically structured data of book classification with "art" as a root node as shown in FIG. 2 is displayed. In this operation example, as shown in FIG. 3, one hierarchical level is represented by one rectangular area, and the connection relation between the nodes is represented by a quadrilateral area. Hereinafter, this operation example will be described in detail based on this example.

In FIG. 3, when there is a parent-child relationship between the hierarchies, the connection relationship is specified by connecting the hierarchies with a quadrilateral region, and when there is no parent-child relationship, the vertical border is made a solid line. Indicates intermittent. In FIG. 3, the “arts” on the second level and the “drama”, “local performing arts”, “popular performing arts”, and “amusement” on the third level are connected by a quadrilateral area, and thus have a parent-child relationship. The second layer "abstract art" has no child nodes since the vertical border is a solid line. In addition, the length of the horizontal border is changed in order to distinguish the case where there is a sibling relationship from the case where there is no sibling relationship. The horizontal boundaries between nodes that have siblings are shorter, and the horizontal boundaries between nodes that are not siblings are longer. For example, in FIG. 3, the second level “drama” and “local arts” have a short horizontal border, so they are in a sibling relationship, whereas the “drama” and “Christian art” have a long horizontal border, No siblings.

Next, the operation of each component described above in this example will be described in detail. For example, it is assumed here that the user has selected “art” 31 in FIG. The folding area determination unit 6 determines the area to be folded and the area to be opened based on the positional information of the point of interest by this input and the connection relationship between the data recorded in the data recording unit 4. In this example, since the area of the point of interest and the area in the connection relationship between the point of interest and the child and the grandchild are opened, the folding area determination unit 6 determines the second hierarchy as the point of interest and the child and the grandchild. Open the third and fourth layers, which are areas in a connection relationship,
Decide to fold the rest.

Next, the overlapping position is calculated by the overlapping position calculating section 7. In this example, the hierarchy to be opened does not overlap with the others, and is overlapped so that the character string of the node can be seen by 1.5 characters on the folding hierarchy. Therefore, the second layer is overlapped so that the character string "art" of the node of the first layer, which is the layer to be folded, can be seen for 1.5 characters. These results are sent to the display unit 5 and displayed. As a result, as shown in FIG. 4, the second layer, the third layer, and the fourth layer including the point of interest “art” 41 are opened, and the remaining first layer is folded and overlapped. A screen is displayed in which the character string is visible for 1.5 character strings.

Note that the data display method is not limited to the display method in the above-described operation example, and it is not necessary to explicitly represent an area by a rectangle as shown in FIG. For example, as shown in FIG. 5, by using a link expression that connects the head of the character string of the parent node and the head of the character string of the child node,
A similar effect can be obtained even with an expression similar to a conventional tree expression. For example, a three-level hierarchical structure with “entertainment” as a root node will be described with reference to FIG. 5. The hierarchical structure shown in FIG. 5 is composed of a head of a character string of a parent node and a head of a character string of a child node. Are represented by connecting them with smooth curves. In this example, it is assumed that the second layer is folded to save the display area. The folding area determination unit 6 and the overlapping position calculation unit 7 perform the same determination and calculation as in the above-described operation example, and send the result to the display unit.
FIG. 6 shows an example of a screen in which the second hierarchy is folded. Although the third level is superimposed on the second level, the nodes of the second level, "local arts" and "popular performing arts", are also visible in the first two characters. As described above, the present invention can be applied to a case where a region is not explicitly expressed.

The target data structure is not limited to a hierarchical structure, but may be a list format, a table format, an image, or the like. For example, an example in which the present invention is applied to tabular data will be described. Hereinafter, an example will be described in which the horizontal axis of the table indicates the month and the vertical axis indicates the budget item. In the above-described example of the hierarchical structure, the point of interest and an area in which the child and the grandchild are connected to each other are described. In the following example, the columns on both sides of the point of interest are opened, and the rest is folded. An example will be described. As an initial state, a table is shown in which the columns of January, February and March are opened and all are visible, and the remaining columns are folded and only partially visible. Here, for example, if the user designates the point of interest as May, the data of May, April and June will be opened and all data will be visible, and the remaining columns will be a folded table.
This makes it easier to see not only May, but also months before and after the point of interest. Next, assuming that the point of interest is August, similarly, July, August, and September open, and the rest becomes a folded table. In a conventional application generally called spreadsheet software, it is necessary for the user to change the display width of each column each time. However, in the present invention, the width can be changed only by specifying a point of interest.

As described above, by performing the folding display, the display area can be more effectively used, and the listability can be improved.

(2) Second Embodiment Next, FIG. 7 is a block diagram showing a configuration according to a second embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG.

This embodiment enables more precise control of the overlapping position by using the history of the point of interest of the user in the first embodiment. Hereinafter, only components different from those in the first embodiment will be described.

Reference numeral 71 denotes a history recording unit for recording the position information of the user's point of interest sent from the input means 1 as a history.

An example of the operation will be described below. Similar to the first embodiment, an example of a hierarchical structure of book classification with “art” as a root will be described. Then, as in the first embodiment, it is assumed that one hierarchy is represented by one rectangular area, and the connection relation between the nodes is represented by a quadrilateral area. In this embodiment, when the width of the layer having the previous point of interest is set to 4 in the overlap position calculating section 72, the width of the layer having the point of interest two times before is set to 3, and the width of the layer of the point of interest before that is set to 3. 2. An example will be described in which the overlapping position is determined at a ratio such that the width of a hierarchy that has never been focused on is 1. In the following description, the width of a hierarchy is defined and described as the width of a portion where a character string indicating a node of the hierarchy is visible. In the same manner as in the first embodiment, the description will be made assuming that the folding area determination unit 6 opens the hierarchy of the current point of interest and the level of the connection between the layer of the point of interest and the child and grandchild.

FIG. 8 shows an initial state. It is assumed that the first point of interest is the route “art” 81. Therefore, the first hierarchy having the point of interest “art” 81 and the two hierarchies of its children and grandchildren are open.

Here, for example, it is assumed that the user has selected and input “Oriental art” on the third level in FIG. The folding area determination unit 6 determines to open the third layer having the current point of interest “Oriental art” and the fourth and fifth layers, which are the layers of its children and grandchildren.

Next, the overlap position is calculated. The overlap position calculation unit 72 calculates the overlap position of each layer based on the position information of the past point of interest recorded in the history recording unit 71. The overlap position calculation unit 72 determines the position of each layer so that the ratio of the width of the first layer having “art”, which is the previous point of interest, to the width of the second layer that has never been selected is 4: 1. Calculate coordinates. This result is sent to the display unit 5.
FIG. 9 shows a screen example in this state. The current point of interest, "Oriental Art" 93, is open and does not overlap any hierarchy. In addition, the first level 91 having "art", which is the previous point of interest, can be seen about three characters from the beginning. The second layer 92, which has not yet become the focus, overlaps with the other layers and is almost invisible. In the present embodiment, the sixth level, which is the last level, is the lowest level and clearly indicates that no levels exist below it. Therefore, the sixth level is always open regardless of the position of the point of interest. I have.

Next, in this state, “Japanese art” 9 on the fourth level
Assume that 4 is selected. As in the above-described example, the folding area determination unit 6 determines to open a hierarchy that is a current point of interest “Japanese art” and its children and grandchildren. Next, the overlap position calculation unit 72 once pays attention to the width of the third layer having the “point of interest” of the previous point of interest and the width of the first layer having the point of “art” two times before. The overlapping position is determined such that the ratio of the width of the second layer that is not performed is 3: 2: 1. FIG. 10 shows an example of a screen in this state. Here, the third level 103, which is the previous point of interest, can be seen about three characters from the beginning, and the first level 101, which is the point of interest two times before, can be seen about one character from the beginning. The second hierarchy 102 that is not selected is hardly visible.

As described above, by using the selection history of the point of interest of the user, the degree of overlap can be controlled, and the listability can be further improved.

(3) Third Embodiment FIG. 11 is a block diagram showing a configuration according to a third embodiment of the present invention. A configuration according to the present embodiment will be described with reference to FIG. Hereinafter, Embodiment 1 will be described.
Components different from those described above will be described.

Reference numeral 111 denotes a movement relation definition unit for defining an area to be moved in conjunction with the movement.

Reference numeral 112 denotes an area moving unit that moves an area that is connected to the area of interest defined by the movement relation definition unit 111 in conjunction with a movement performed by the user to move the area of interest.

In the following example, a description will be given of an example in which a node having a connection relationship with a point of interest is defined by the movement relationship definition unit 111 so as to move in conjunction therewith.

An example of the operation will be described below. As in the first embodiment, a description will be given using an example of a hierarchical structure of book classification with “art” as a root node. First, the user uses the input unit 1 to specify a region to be moved. For example, let the area 121 in FIG. 12 be the area specified by the user. Next, the user moves the area to a desired position. In this example, the area moving unit 112 links an area having a connection relation with the area specified by the user in accordance with the movement relation between the areas defined by the movement relation definition unit 111 in accordance with the movement of the area specified by the user. To move. The result is sent to the display unit 5.

FIG. 13 is a view showing a state where the area 121 in FIG. 12 is slightly moved. An area 131 indicates a position of the area 121 after the movement. FIG. 14 shows a state where the area 131 is further moved. The area 141 in FIG. 14 indicates the position of the area 131 in FIG. 13 after the movement. The area moving unit 112 is connected to the area 14
2. The area 143 is moved in conjunction with the movement of the area 141.

In the operation example described above, an example has been described in which objects having a connection relationship with a point of interest are moved in conjunction with each other, but the relationship defined in the movement relationship definition unit 111 is arbitrary. For example, an even layer and an odd layer may be defined to move in conjunction with each other. The direction of movement is also arbitrary. For example, only the related area may be moved in the vertical direction of the screen in conjunction with the movement. Further, as described above, the present invention may be applied to a table format. When applied to the table format, for example, it is possible to simultaneously move a plurality of related columns to an easily viewable position.

By providing the area moving section as described above, it is possible to move a plurality of areas which are connected to the one area simply by moving one area, so that the user can easily understand the area. Since the arrangement can be performed efficiently, the listability is improved as a result.

(4) Fourth Embodiment FIG. 15 is a block diagram showing a configuration according to a fourth embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG. Hereinafter, Embodiment 1 will be described.
Components different from those described above will be described.

Reference numeral 151 denotes a structure emphasizing unit for changing the expression of the area according to the data structure in order to emphasize the data structure. The way of expression here is arbitrary, such as color, shape, gradation, and fill pattern.

In the following operation example, an example using a filling pattern will be described. Further, the way of assigning the correspondence with the data structure is also arbitrary. In the following operation example, an example will be described in which five different patterns are applied in a contour line around the point of interest.

An operation example will be described below. As in the first embodiment, a description will be given using an example of a hierarchical structure of book classification with “art” as a root node. FIG. 16 shows an example of an actual screen. In this example, the point of interest is "Japanese architecture" in the area 1601.
FIG. "Japanese architecture" is the focus
And its child node 1607 are the filling pattern 1.
"Nihonga" is a sibling node of "Japanese architecture"
And "Japanese sculpture" and its descendant node 160
6, the node 1610 and the node 1614 are the filling pattern 3. "Garden-Japan" and "Buddhist art" and their descendant nodes, node 1605 and node 160
8. The pattern 16 is the node 1611. "Painting-
Pattern 5 is “Japan” and its descendant nodes, node 1604, node 1609, node 1612, and node 1613. Also, nodes 1602 and 1603, which are ancestor nodes of the point of interest "Japanese architecture", are filled with pattern 2. As described above, the sibling nodes are separately painted in a contour line around the point of interest, so that the structure can be easily grasped and the listability can be improved.

As described above, the manner of emphasizing the structure is not limited to the fill pattern. FIG. 17 shows an example in which the structure is emphasized by the shape. The structure is emphasized by expressing nodes having a connection relationship in the same shape. For example, the nodes 171 and 172 represented by semicircles are represented by semicircles, and the nodes 173 and 174 are represented by triangles.

As described above, the structure is clearly specified by providing the structure emphasizing unit. Therefore, even when the data amount increases, the structure can be easily grasped and the listability can be improved.

(5) Fifth Embodiment Next, FIG. 18 is a block diagram showing a configuration according to a fifth embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG. Hereinafter, Embodiment 1 will be described.
Components different from those described above will be described.

Reference numeral 181 denotes a data display attribute control unit for expressing data attributes by display attributes of the area. Here, the data attribute to be expressed is arbitrary. For example, data amount, presence / absence of selection in the past, access frequency, importance, and the like. These data attributes are recorded in the data recording unit 4. Also, the display attributes used for expression are size, shape,
The color, gradation, etc. are arbitrary.

Hereinafter, an operation example of expressing the data amount by the shape of the area will be described. When the data amount is larger than a certain reference value, the boundary line of the area is expanded in the horizontal direction, and when the data amount is smaller than the certain reference value, the boundary line of the area is concaved in the horizontal direction. Then, as the data amount becomes farther from the reference value, the ratio of expansion or depression is increased.
Here, for example, as shown in FIG.
Suppose there are three nodes of "art". And "Entertainment"
Data volume of "Abstract Art" is 80,
Assume that the data amount of “art” is 180, and the reference value is 10
Assume that it is 0. The data display attribute control unit 181 assigns a display attribute (in this case, shape) to each data attribute (in this case, the data amount). "Entertainment" is considerably lower than the reference value, so a large concave shape is assigned. "Abstract art" is slightly smaller than the reference value, so a slightly concave shape is assigned. Since "art" is considerably larger than the reference value, a greatly expanded shape is assigned. FIG. 19 shows these states. It can be seen that the “entertainment” 191 in FIG. 19 is slightly less than the reference value because the boundary of the area is slightly depressed in the horizontal direction. Also, since the area of the “abstract art” 192 is greatly depressed, it is considerably smaller than the reference value.
Since 93 is greatly expanded, it can be seen that the data amount is considerably larger than the reference value.

The display attribute to be associated is not limited to the shape.
For example, it is naturally conceivable to associate the area with the area of each node. In the following, a description will be given using an example in which the data amount is associated with the area of the node. Specifically, the area of a node is represented by changing the position of the boundary line of each node.
Here, for example, it is assumed that the data amount of “entertainment” is 60, the data amount of “abstract art” is 40, and the data amount of “art” is 120. The display attribute control unit 181 assigns a display attribute (in this case, a position of a boundary line of a node) to each data attribute (in this case, a data amount). The amount of each data is proportionally distributed to the horizontal size of the area, and the position of each boundary line is determined. In this example, "entertainment": "abstract art":
Since "art" = 60: 40: 180 = 3: 2: 6, the position of the boundary line of the node is determined according to this ratio. With this determination, each area ratio is directly proportional to each data amount. FIG. 20 shows a screen in this state. The “art” 203 having the largest area has the largest data amount, and then the “entertainment” 201 and the “abstract art” 202 have the largest data amount. Further, from the area ratio, the data amount ratio is 3: 2: 6. It turns out that it is about.

As described above, by representing the data attribute in association with the display attribute, the contents of the data can be grasped more intuitively, and the listability can be improved.

(6) Sixth Embodiment FIG. 21 is a block diagram showing a configuration according to a sixth embodiment of the present invention. The configuration according to the present embodiment will be described with reference to FIG. Hereinafter, Embodiment 1 will be described.
Components different from those described above will be described.

Reference numeral 211 denotes an enlargement / reduction display control unit for enlarging an area near the point of interest and reducing an area around the point of interest based on the position information of the point of interest input from the input means 1.

An operation example will be described below. In this operation example, an example will be described in which the point of interest and its descendant nodes are enlarged in the vertical direction on the screen, and the other nodes are reduced in the vertical direction on the screen. Also, an example will be described in which the enlargement ratio is such that when the reduced portion is 1, the enlarged portion is 4.

First, the user specifies a point of interest using the input means 1. Based on the position information of the point of interest, the enlargement / reduction display control unit 211 enlarges the display near the point of interest and reduces its periphery. This result is sent to the display unit 5. FIG.
Here is an example of enlarged and reduced display. The figure shows "Japanese Architecture" 1
This is an example of a case where 71 is the point of interest. The "Japanese architecture" 221 as the point of interest and its descendant nodes "Painting-Japan" 222, "Japanese painting" 223, and the like are enlarged and displayed in the vertical direction. "Buddhist art" 224 around the area
, “Buddhist picture” 225 and the like are reduced in the vertical direction.
Even if the data amount is increased by the enlargement / reduction display, the vicinity of the point of interest, which is the node that the user wants to see, is enlarged and displayed, and the listability for the user is improved. Note that the point to be enlarged, the enlargement ratio, the direction, and the like are not limited thereto.

As described above, by expanding the point of interest and reducing the area around the point of interest, the display area can be more effectively used and the listability can be improved.

Further, in order to implement the information display device of the present invention by a computer, for example, the first embodiment described above is used.
In the configuration of (1), a computer program for generating a folding display control unit is created inside the computer, and the computer program is recorded on a recording medium represented by a CD-ROM, a floppy disk, or a semiconductor memory. By reading the recording medium on which this program is recorded, the folding display control unit is generated inside the computer, and the configuration described in the first embodiment of the present invention can be constructed. The computer program may be in a form recorded in a recording device in the server, for example.
A form provided via a network may be used.
Furthermore, in this description, only the case of Embodiment 1 has been described, but the same applies to other embodiments.

[0065]

As described above, according to the present invention,
By performing the folding display, there is an effect that the display area can be more effectively used and the listability can be improved.

Further, by using the selection history of the point of interest of the user, the degree of overlap can be controlled, and the listability can be further improved.

Further, by providing the area moving unit, it is possible to move a plurality of areas connected to the area only by moving one area, so that the user can easily understand the area layout. As a result, the listability is improved as a result.

Further, since the structure is specified by providing the structure emphasizing unit, the structure can be easily grasped even when the data amount increases, and the listability can be improved.

By expressing the data attributes in association with the display attributes, the contents of the data can be grasped more intuitively, and the listability can be improved.

Further, by enlarging the point of interest and reducing the area around the point of interest, the display area can be more effectively used and the listability can be improved.

Further, according to the present invention, it is possible to provide an information display device which solves the problems of the conventional technology and has improved browsability.
