DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for displaying a structure in an information processing apparatus such as a computer, and more particularly to a hierarchical structure of files, a classification structure of books, an organization chart such as personnel affairs, a map, and a network. The present invention relates to an information display device suitable for display.

[0002]

2. Description of the Related Art Generally, when displaying a structure, global information (overall image and structure) and local information (details of each information) are displayed.
It is necessary to display both. However, it is not easy to display both the global information and the local information at the same time due to restrictions such as the size of the screen of the display device.

To solve the problem that it is difficult to achieve both global information and local information at the same time, a fisheye display method has been proposed. This fish-eye display method is a method in which a part that the user is paying attention to is displayed large and a part that is not paying attention is displayed small, so that the whole image can be displayed while displaying details in the vicinity of the point of interest. For example, in the literature (Manojit Sarka
r and Marc H. Brown, “Graphical Fisheye Views
of Graphs ”, Proceedings of CHI, 1992, ACM, N
ew York, 1992, pp83-91), defines a coordinate system with the point of interest as the origin, calculates the transformation of the position of each point as a function of the distance between each point and the origin, and calculates the position of each point. There is proposed a method of converting and distorting and displaying.

[0004] For example, Japanese Patent Application Laid-Open No. Hei 7-93565 discloses that when a user has a plurality of points of interest in a structural area, a position in the structural area is designated with the point of interest as a focus, and a detailed structure near a plurality of focal points is provided. A structure display method has been proposed in which the entire structure can be simultaneously displayed as a continuous structure. This structure display method considers a potential that is inversely proportional to the distance from the point of interest, calculates a vector that combines vectors representing the potentials of all focal points for each point in the structure region, and has a plurality of points of interest. Even in this case, the position of each point in the structure area can be calculated.

[0005]

However, the conventional fish-eye display system has the following problems.

A first problem is that it is difficult to understand the connection between operations. The reason is as follows.

In the fish-eye display method, focusing on a certain point,
The vicinity of the point is enlarged and displayed, but the point of interest before that point is displayed small. When the previous point of interest is reduced, the connection (association) between the current operation and the previous operation becomes difficult to understand, and the user does not easily lose his or her position.

[0008] The second problem is that the operation efficiency is poor. The reason is as follows.

[0009] When comparing a plurality of points of interest, comparisons are often made between portions that are temporally connected in the search process, such as the present and immediately before. However, in the conventional fisheye display method, each point of interest must be explicitly specified, and the user must also explicitly release the point of interest.

[0010] When comparing a plurality of points of interest, comparison is often made in a temporally close part in the search process, such as immediately before and now, but in the conventional fisheye display method,
Designation and cancellation of the point of interest must be explicitly performed each time, thereby preventing an improvement in operation efficiency.

Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to leave the previous point of interest in a certain size so that the current operation and the previous operation can be performed. It is an object of the present invention to provide an information display device that has a connection to prevent a user from losing his / her own position, and that automatically controls a display attribute of a point of interest to improve operation efficiency.

[0012]

In order to achieve the above object, a first invention of the present application (claim 1) reflects a data recording unit for recording data to be displayed and a logical structure of the data. Structural interest calculating means for calculating the degree of interest of each point (referred to as "structural degree of interest"), point of interest designating means for specifying a point of interest, and a history recording unit for recording a selection history of the point of interest. , A temporal interest calculation means for calculating the temporal interest of each point from the history of the past points of interest and the current point of interest,
Comprehensive interest calculation means for calculating a total interest from the temporal interest and the structural interest, display control means for associating the total interest with a display method, A display unit for performing display based on the display method determined by the display control means.

The second invention of the present application (claim 2) further comprises a calculation method setting means for providing means for a user to set a calculation method of the degree of interest in the first invention.

According to a third aspect of the present invention (claim 3), a history designating means for designating a past state to be reproduced, and position information of each focus point from an initial focus point to a focus point designated by a user. And a point-of-interest transmission unit that sequentially transmits the interest points to the interest calculation unit.

Further, the fourth invention of the present application (claim 4) includes an interest level pattern recording unit for recording the interest level pattern of the user, and a user interest level pattern based on the transition of the point of interest of the user in the history recording unit. And a degree of interest pattern identification unit that identifies

According to the first invention of the present application (claim 1), when the point of interest moves, the user loses his or her position by performing display control so that the past point of interest also keeps a certain size. And improve operation efficiency.

Embodiments of the present invention will be described below with reference to the drawings.

[0021]

Embodiment 1 FIG. 1 is a block diagram showing a configuration of a first embodiment of the present invention. Referring to FIG. 1, in this embodiment, a data recording unit 1 in which data to be displayed is recorded, and a structural interest calculating unit which calculates an interest of each point by reflecting a logical structure of the data. 2, a point of interest specifying means 3 for specifying a point of interest, a history recording unit 4 for recording a history of selection of the point of interest, a time of each point from the history of the past point of interest and the current point of interest. Temporal interest calculator 5 for calculating the degree of interest, total interest calculator 6 for calculating the overall interest from temporal interest and structural interest, and total interest and display method And a display unit 8 that performs display based on the display method determined by the display control unit 7.

The point-of-interest designation means 3 is composed of, for example, a pointing device such as a mouse. History recording unit 4
Records the identification number of each history, the order of selection, coordinates, display contents, and the like.

The structural interest calculator 2, the temporal interest calculator 5, the total interest calculator 6, and the display controller 7 will be described in detail below.

The temporal interest degree calculating section 5 comprises a function for calculating the temporal interest level of the user. As this function:
Any function can be specified. For example, a function may be considered in which the degree of interest decreases in the past and the current point of interest is maximized, and monotonically decreases as the point of interest is selected before.

Here, as one embodiment, the temporal interest level of the current point of interest is "10", the temporal interest level of the immediately preceding point of interest is "9", and the following " An example of a function that gives a value reduced by one such as “8” or “7” will be described.

The total interest level calculator 6 calculates a total interest level from each interest level. The method of calculation is arbitrary. For example, a method of simply summing the degrees of interest or a method of summing with weights can be considered.

Here, as one embodiment, a method is employed in which the interest levels are simply summed (ie, without weighting) within a range not exceeding “10”. More specifically,
If the sum does not exceed "10", the sum is the sum, and if the sum exceeds "10", the sum is "10".

The display control unit 7 associates the overall interest level with the display method. The display method for associating with the overall degree of interest is, for example, any of display size, gradation, transparency, arrangement, color, shape, and the like.

Further, the manner of associating the display attribute value with the overall interest level in each display method is arbitrary, and the optimum association is set according to the purpose and use. For example, when associating with magnitude, magnitude and overall interest may be associated with a linear function, or a quadratic function, a logarithmic function,
You may make it correspond with a more complicated function, such as an exponential function.

Here, as an embodiment, an example in which the correspondence is performed by a linear function will be described. FIG. 2 shows a specific example of the linear function. Referring to FIG. 2, the correspondence is set so that the display size when the interest level is “10” is exactly twice the display size when the interest level is “0”. For this reason,
Assuming that the size at the time of interest "10" is a reference (= 1), the size at the time of interest "9" is 0.95 times the size at the time of interest 10 and the interest "8". In the case of, it becomes 0.9 times.

Next, the operation of the first embodiment of the present invention will be described with reference to an example. FIG. 3 is a diagram for explaining the operation of the embodiment of the present invention, and shows a hierarchical structure of book classification with “education” as a root node.

Referring to FIG. 3, a node is a name of a category item, and a link indicates a conceptual hierarchical relationship between the category items. For example, the child nodes of the “education” node 20, “Ikuei Business”, “school”, “home education”, “compulsory education”, and the like are subordinate concepts of “education”.

Here, it is assumed that the user has selected "social education" 21 using the point of interest designating means 3 (see FIG. 1) composed of a pointing device such as a mouse.

First, the degree of structural interest of the user is calculated by the structural degree of interest calculator 2. In the present embodiment, the degree of structural interest of descendant nodes having the point of interest as the vertex is uniformly “1”.
Since “0” is set to “0” and the others are set to “0”, the degree of structural interest is as shown in FIG.

Next, the temporal interest level is calculated by the temporal interest level calculator 5. In this case, since the operation of selecting the “social education” 21 by the point-of-interest designation unit 3 is the first operation, no history is recorded in the history recording unit 4. Therefore, the temporal degree of interest is equal to "0" at all nodes.

Next, the overall interest level calculation unit 6 calculates the overall interest level of the user. In the present embodiment, the sum of the structural interest and the temporal interest is obtained (however, “1”
0 is set as the upper limit).

In this case, since the temporal interests are all “0”, the total interest has the same value as the structural interest.

Finally, the display control unit 7 associates the overall interest level with the display method. In this embodiment, the degree of interest and the size of the display correspond to each other by a linear function (see FIG. 2). Display is performed on the display unit 8 according to the display method associated with the display control unit 7. The display result is shown in FIG.

Referring to FIG. 5, in this embodiment,
As a result of selecting “social education” 21 by the point-of-interest designation means 3, descendant nodes having “social education” 21 as the top are enlarged, and other nodes are displayed in a reduced size.

Next, it is assumed that the user has selected "library" 22. The degree of structural interest is calculated in the same manner as described above. The degree of structural interest is “10” for descendant nodes having the “library” 22 as the vertex, and “0” for other nodes.

Next, the degree of temporal interest is calculated. The degree of temporal interest is as follows: the descendant node having the current point of interest "Library" 22 at the top is "10", and the descendant node having the previous point of interest "Social Education" at the top is "9". is there. Therefore, the overall degree of interest is as shown in FIG.
In FIG. 6, the size of the display is already changed according to the magnitude of the degree of interest in order to make the relationship between the degree of interest and the size of the display easy to understand.

Next, the display control section 7 associates the overall interest level with the display method. Figure 7 shows the display results
Shown in

Referring to FIG. 7, the partial tree under "library" 22 which is the current point of interest is naturally expanded, but the partial tree under "social education" 21 which is the previous point of interest is also somewhat larger. It is displayed enlarged in size. That is,
The subtrees under “Social Education” 21 which is the previous point of interest are:
When the size of the display area of the current point of interest is “1”, it is displayed at “0.95” times.

It is further assumed that the user selects "school library" 23. The method of calculating the degree of structural interest is the same as described above.

The degree of temporal interest is “10” for the descendant node having the current point of interest “school library” 23 at the top, and “9” for the descendant node having the previous point of interest “library” 22 at the top. The descendant node having “Social Education” 21, which is the point of interest two times before, at the top is “8”. When the overall degree of interest is obtained from the structural degree of interest and the temporal degree of interest, the result is as shown in FIG. Then, the overall degree of interest and the display method are associated with each other in the same manner as the previous time. FIG. 9 shows the final display result.

Referring to FIG. 9, the partial tree below the "library" 22 which is the previous point of interest is also displayed with a certain size left. That is, in this example, when the current point of interest is “1”, it is displayed in the size of “0.95”. "Social education" which is a point of focus two times before
Subtrees of 21 or less are also displayed in a certain size. That is, in this example, when the current point of interest is “1”, it is displayed in a size of “0.9”.

As described above, in this embodiment, by reflecting the past history on the display, the previous point of interest can be left with a certain size, and the connection between the operation and the display can be easily grasped. Thereby, the operation efficiency is improved.

In the example described above, the past point of interest is enlarged and left. However, since the point of interest once is considered to be no longer interested, the past point of interest is reduced from the normal point. May be displayed. In this case, the temporal interest degree calculation unit 5 may associate the temporal interest degree of the past point of interest with a lower level than the unselected point. An example of this operation will be described below.

FIG. 10 is a diagram showing that “school” 24 has been selected by the point-of-interest designation means 3 from the initial state.
FIG. 1 is a diagram illustrating a state where “education for the disabled” 25 is further selected. At the time of selecting "Education for the Disabled" 25,
It can be seen that "school" 24 or less, which is the previous point of interest, is displayed small.

Next, a second embodiment of the present invention will be described below. In the above-described embodiment, the overall degree of interest is associated with the size of the display area, but a display method for associating with the overall degree of interest is arbitrary. In this embodiment, a case will be described in which the overall degree of interest is associated with the degree of transparency. In the present embodiment, the configuration of the apparatus is the same as that of the first embodiment (see FIG. 1), but the display control unit 7 associates the total interest level with transparency instead of size. The difference was that In this embodiment, as shown in FIG. 12, the higher the overall interest level, the lower the transparency.

An example of the operation of this embodiment will be described below. For example, in the structure shown in FIG. 3, it is assumed that the user first selects “social education” 21 and then “library” 20. FIG. 13 shows a display screen in this case.

Referring to FIG. 13, "library" which is the current point of interest is displayed at the center of the screen.
Each node one layer below is displayed translucently superimposed. In this display, the column starting from “school library” (left column) is a child node of “library”, and thus has a high degree of interest and has low transparency. The column starting from "Youth hostel" (center column)
Although it is not a child node of "library", it is a descendant node of "social education" which is the focus of the previous time, so the transparency is moderate. In addition, the column starting with "high school student" (right column) is not a descendant of the point of interest selected in the past,
Interest is low and transparency is high.

As described above, in this embodiment, it is possible to prevent the screen from becoming complicated by changing the transparency by reflecting the past history.

[0054]

Embodiment 2 The second embodiment of the present invention will be described below. FIG. 14 is a block diagram showing the configuration of the second embodiment of the present invention. In this embodiment, a user can control a display method.

Referring to FIG. 14, this embodiment is different from the embodiment shown in FIG.
This is a configuration in which calculation method setting means 9 is added to the configuration of the first embodiment shown in FIG. Other configurations are the same as those of the first embodiment, and therefore, the differences from the first embodiment will be mainly described below.

The calculation method setting means 9 is a means for the user to set the calculation method of the degree of interest, and is actually realized by a slider or an object on the screen which can be directly operated. The setting items include, for example, the shape of a function of the degree of interest (straight line / curve, inclination, convex upward / convex downward, etc.).

The operation of the second embodiment of the present invention will be described below in accordance with one embodiment. This example is
This is an example in which the graph of the association function is displayed on the screen, and the user directly deforms the graph (see FIG. 15). FIG.
FIG. 15B is a graph showing the correspondence between the degree of interest and the size of the display method. FIG. 15B is a graph showing a function generated by transforming the linear function of FIG. 15A by the user. .

The user can change the function by moving the sample points. Referring to FIG.
The shape of the function is changed from a straight line (see FIG. 15A) to an upwardly convex curve (see FIG. 15B). Due to this deformation, a difference in size in a portion having a high degree of interest can be reduced as compared with before the deformation.

For example, it is assumed that “element”, “polymer chemistry”, and “analytical chemistry” have been selected in the book classification structure with chemistry at the top.

FIG. 16 shows an example in the case of linearization.
FIG. 17 shows an example of an upwardly convex curve. In the case of an upwardly convex curve, there is a small difference in the display area size between “analytical chemistry” 26 and “polymer chemistry” 27, which are points of interest close to the present time, but it is further displayed as the “element” 28 before that. The area is suddenly smaller.

By controlling the display method by the user himself, a display more suitable for the user can be provided.
Operation efficiency is improved.

[0062]

Third Embodiment A third embodiment of the present invention will be described below. FIG. 18 is a block diagram showing the configuration of the third embodiment of the present invention. In this embodiment, a past state can be reproduced by designating a past point of interest.

Referring to FIG. 18, in the third embodiment of the present invention, the configuration of the apparatus is the same as that of the first embodiment shown in FIG. And a transmission unit 10. Below,
The description of the same parts as those in the first embodiment will be omitted, and different points will be mainly described.

The history designating means 11 is a means for designating a past state to be reproduced, and comprises, for example, a slider on the screen.

The point-of-interest transmission unit 10 sequentially sends the position information of each point of interest from the initial point of interest to the point of interest specified by the user to the interest calculation unit.

FIG. 19 is a flowchart showing an example of the flow of processing of the point-of-interest transmission unit 10 as an example of the third embodiment of the present invention. Note that FIG. 19 shows an example, and the point-of-interest sending unit 10 can apply various methods and modifications other than the above. Referring to FIG. 19, the point of interest sending unit 10 sequentially extracts points of interest from the history recording unit 4 (step S2), and compares whether the point of interest matches the point of interest specified by the history specifying unit 11 (step S2).
4) If they match, send this as the point of interest.

The operation of the third embodiment of the present invention will be described below in accordance with one embodiment. For example, in the structure shown in FIG. 3, it is assumed that the user has selected “social education”, “library”, “school library”, and “class library” in this order. Then, in this state, the user specifies the history
Assume that the user has designated “school library”, which is the previous point of interest, by using “1”.

The history specifying means 11 sends the identification number of the point of interest specified by the user to the point of interest sending section 10. The point-of-interest transmission unit 10 sequentially records information from the first point of interest, ie, “social education” in this case, to the point of interest specified by the history specifying unit 11, in this case, “school library”. And sequentially sends them to the structural interest calculator 2 and the temporal interest calculator 5.

The structural interest calculation unit 2 and the temporal interest calculation unit 5 recalculate the interest based on the information of each point of interest. Through these procedures, any state selected by the user in the past can be reproduced.

As described above, in the third embodiment of the present invention, since the past state can be reproduced, the user can confirm the process so far, and the user is less likely to lose his or her position.

[0071]

[Fourth Embodiment] A fourth embodiment of the present invention will be described below. FIG. 20 is a block diagram showing the configuration of the fourth embodiment of the present invention. In this embodiment, a plurality of interest degree patterns recorded in advance are selectively used in accordance with the purpose of the user, so that display control more suitable for the purpose of the user is performed.

In the fourth embodiment of the present invention, the configuration of the apparatus is different from the configuration of the first embodiment shown in FIG. 1 in that an interest pattern recording unit 12 and an interest pattern identification unit are further included. 13 are added. In the following, the description of the same parts as those in the first embodiment will be omitted, and different points will be mainly described.

The interest level pattern recording section 12 can record an arbitrary interest level pattern. In the following, as examples, a breadth-first search pattern, a depth-first search pattern,
An example will be described in which three interest degree patterns of random search patterns are prepared.

Each pattern is shown in FIGS. 21 to 23.

FIG. 21 shows a breadth-first search pattern. Referring to FIG. 21, this breadth-first search pattern is:
A pattern is assumed in which nodes in the same hierarchy are sequentially searched in the width direction. For this reason, a pattern in which the degree of interest does not change much is prepared, considering that the difference in the degree of temporal interest of each point of interest is small.

FIG. 22 is a diagram showing a depth-first search pattern. This pattern is assumed to be a pattern in which a search is performed from the upper hierarchy to the lower hierarchy in the depth direction.
For this reason, the upper node is relatively remembered because it is semantically continuous. Therefore, there is a difference in the degree of temporal interest.

FIG. 23 is a diagram showing a random search pattern. In this pattern, past points of interest are considered to have little relationship with each other, and the temporal interest level is exponentially reduced as the points of interest become past.

Referring again to FIG. 20, interest level pattern identification section 13 identifies the interest level pattern of the user from the transition of the point of interest of the user in history recording section 4. The identification method is arbitrary, but as an example, a case where the transition of the point of interest always satisfies the parent-child relationship is a depth-first search pattern, and a case where the transition of the point of interest is performed in the same hierarchy. The breadth-first search pattern and other cases are regarded as random search patterns.

The operation of the fourth embodiment of the present invention will be described below in accordance with one embodiment. For example, in the structure shown in FIG. 3, it is assumed that the user selects “social education”, “library”, and “school library” in this order. The interest level pattern identification unit 13 finds out from the transition of the point of interest in the history recording unit 4 that the user has sequentially selected nodes satisfying the parent-child relationship, and identifies this as a depth-first search pattern. Because of this, it ’s a depth-first interest pattern,
In accordance with the definition of the depth-first pattern of interest described above, a past point of interest is displayed at a medium size. FIG. 9 shows a screen in this state.

Next, when the user enters “adult education” 29, “university”
It is assumed that 30 and “museum” 31 are selected. According to the same procedure, the interest level pattern identification unit 13 identifies the pattern as the width priority pattern. Since the width priority pattern is used, the size of the display area at each point of interest does not change much. The screen in this state is shown in FIG.
Shown in

It is further assumed that the user has selected "infant education" 32. Since the interest level pattern identification unit 13 does not apply to either the depth priority pattern or the width priority pattern, it identifies the pattern as a random search pattern.

As described above, the random search pattern is a pattern on the assumption that the degree of interest decreases exponentially with the past. Therefore, as shown in FIG. The “museum” 31 is displayed in a certain size, but the point of interest before that is almost the same as the size of the non-point of interest.

In the fourth embodiment of the present invention, by preparing the interest level pattern in this way, it is possible to perform display in accordance with the transition of the interest level of the user.

[0084]

As described above, according to the present invention,
By reflecting the past history on the display, the previous point of interest can also be left on the screen with a certain display size, making it easy to understand the connection of operation and display, improving operability especially, As a result, there is an effect that the operation efficiency is improved.

Further, according to the present invention, by providing a means for the user to set the calculation method of the degree of interest, it is possible to perform a display more suitable for the user, and to improve the operation efficiency. Play.

Further, according to the present invention, since the past state can be reproduced, it is possible to prevent the user from losing his / her own position and to improve the operability.

Further, according to the present invention, by preparing a degree of interest pattern, it is possible to perform display in accordance with the transition of the degree of interest of the user, thereby reducing the psychological load on the user and improving operability. It has the effect of improving.
