Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for displaying a list of data registered in a database such as a term dictionary and an address book, and a recording medium on which an information display program is recorded.

[0002]

2. Description of the Related Art Generally, personal computers and PDs
In various information processing apparatuses such as A (personal digital assistant), when a list of data registered in a database such as a term dictionary and an address book is displayed in a list, a scroll bar and an index display (item name list) as shown in FIG. Display) is added.

In the index display, a list of each item is displayed when all displayable data is classified into predetermined items. The example shown in FIG. 10 indicates that the data is sorted in the order of the Japanese syllabary, the symbol, and the alphabet. Each item displayed in the index is associated with data, and by selecting an arbitrary item from the index display, a list of data corresponding to the item can be displayed. In the example shown in FIG. 10, the item “ta” is selected and the data of the “ta” row is displayed in a list.

On the other hand, the entire length of the scroll bar indicates the number of all data, and each position of the scroll bar is associated with data. When a dragger provided in the scroll bar is dragged (operation for changing the display position) by operating a pointing device such as a mouse or a pen, data corresponding to the position of the dragger can be displayed in a list. The size of the dragger can also indicate the range of the data currently being displayed in a list of all data.

[0005]

As described above, in the conventional information processing apparatus, when a list of data registered in a database or the like is displayed, a scroll bar or an index display is added together with the list data. In addition, selection of data to be displayed in a list can be easily performed.

However, in the conventional scroll bar, when the range of the data displayed in the list is represented by the size of the dragger, if the total data that can be displayed is large, the ratio of the data displayed in the list to the total data is large. As a result, the size of the dragger becomes smaller. This makes it difficult to operate the dragger using the pointing device. Further, since the range of the data to be displayed in the list is largely changed only by slightly dragging the dragger, the operation for displaying the desired data in the list becomes difficult.

In the conventional index display, FIG.
As shown in FIG. 0, only a list of items that classify all data is displayed, and the number of data corresponding to each item cannot be grasped at all. It didn't help with scrollbar dragger operations.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is intended for displaying a part of a large amount of data in a list.
It is an object of the present invention to provide an information processing apparatus capable of easily designating a desired data range and a recording medium on which an information display program is recorded.

Are displayed in a list as item names.

[0012] Further, there is provided a search character input means for inputting a search character to be an item to be searched by the search means.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. First, a first embodiment will be described. FIG. 1 is a block diagram showing a configuration of an electronic circuit of an information processing device 10 according to the first embodiment of the present invention. The information processing apparatus 10 is configured by a computer that reads programs recorded on various types of storage media, and whose operation is controlled by the read programs.

The information processing apparatus 10 according to the first embodiment
Can classify all the data that can be displayed for each predetermined item, and perform index display (item name list display) in which the number of data corresponding to each item is represented by its shape (length).

As shown in FIG. 1, the information processing apparatus 10
The CPU 20 is interconnected with the input unit 21, the display unit 22, the communication unit 23, the storage device 24, and the memory 26.

The CPU 20 controls the overall operation of the information processing apparatus 10, and executes various processes by executing programs stored in the memory 26. CPU2
By executing the scroll bar program 26a stored in the memory 26, 0 can execute an indexed scroll bar process (details will be described later) when displaying data registered in the database 26b.

The input unit 21 includes a keyboard, a pointing device such as a mouse, and is used to input data and various instructions.

The display section 22 is for displaying various information, and displays a list of data registered in the database 26b. In the data list display, the scroll bar is displayed together with the data by executing the scroll bar program 26a.

The communication unit 23 controls communication with another computer via a network (not shown) under the control of the CPU 20.

The storage device 24 has a storage medium 24a, and executes recording and reading of programs, data, and the like on the storage medium 24a. The storage medium 24a is magnetic,
It is constituted by an optical storage medium or a semiconductor memory, and is fixedly provided in the storage device 24 or is detachably mounted. Further, the program, data, and the like stored in the storage medium 24a may be received from another device connected via a communication line or the like and stored.
Further, a storage device having a storage medium may be provided on another device connected via a communication line or the like, and a program and data stored in the storage medium may be used via the communication line. . The storage device 24 includes a storage medium 24a
In addition, various data registered as a database can be recorded, read out as necessary, and stored in the memory 26.

The memory 26 stores information on programs and data accessed by the CPU 20 as needed. In the present embodiment, for example, in addition to the scroll bar program 26a and the database 26b, data registered in the database 26b Item 26c, the number of data items per index item 26d, and the sub-index item 26
e, various data such as the number of data items 26f for each sub-index item, the specified data 26g, and the specified index 26h are stored. The memory 26 is provided with a work area for temporarily storing work data, if necessary.

Next, the information processing apparatus 10 of the first embodiment
The operation in the case of performing data display will be described. When execution of list display for data stored in the database 26b is input from the input unit 21, the CP
The U20 activates the scroll bar program 26a stored in the memory 26 and starts the process of displaying the specified data in a list. The CPU 20 displays the data in a list by executing the scroll bar program 26a, and executes an indexed scroll bar process for allowing the data to be displayed in the list to be easily changed according to an instruction from the user.

Here, the indexed scroll bar processing will be described with reference to the flowcharts shown in FIGS.

Here, a case will be described as an example where the term dictionaries (word data) that are sorted and registered in the order of the Japanese syllabary are arranged vertically and displayed in a list. On the right side of the data list display, there is provided an indexed scroll bar for moving the dragger up and down to indicate the data range to be displayed in the list. It is assumed that the overall length of the scroll bar indicates the number of all data that can be displayed, and that the dragger indicates the position of the data that is currently displayed in the list among all the data. Also,
Adjacent to the scroll bar, a list of item names when all displayable data is classified for each predetermined item is displayed as an index. Here, the index display with the first character of each of the Japanese syllabary as "A", "KA", "SA", etc., and, when a specific item is specified, detailed items included in the corresponding item For example, if the item “A” is specified, “A”, “I”, “U” included in the “A” line
A sub-index can be displayed with the characters "e" and "o" as items (see FIGS. 4A and 4B).

First, when execution of list display (list display) for data stored in the database 26b is instructed, the CPU 20 acquires the total number of data to be displayed in the list with reference to the database 26b (step A).
1). Further, the CPU 20 acquires the index item data to add the index display to the data list display (step A2). For example, if the data to be displayed in the list is a term dictionary registered in the order of the Japanese syllabary, all the data are classified with the Japanese syllabary as an item,
It is assumed that each character of the Japanese syllabary is registered in the database 26b as an index item. The CPU 20 acquires items such as "A line", "KA line", and "SA line" from the database 26b as index item data, and stores them in the memory 26 as index items 26c. Then, the index item is set at the head (“A row”) as initial data (step A3).

The CPU 20 obtains the number of data items (data amount) corresponding to the target index (here, "a row") by referring to the database 26b, and stores it in the memory 26 as the number of data items 26d for each index item ( Step A4).

If the next index item is stored as the index item 26c (step A5), the CPU 20 sets the target index item to the next index item (step A6), and similarly sets the target index item. The number of data items corresponding to (here, “ka row”) is acquired by referring to the database 26b, and is stored in the memory 26 as the number of data items 26d for each index item (step A4). Similarly, similarly, each index item stored as the index item 26c is sequentially set as a target index,
The number of data items corresponding to each is acquired and stored as the number of data items 26d for each index item (steps A4 to A6).

When the number of data items corresponding to each of the index items is determined, the CPU 20 determines the number of data items to be displayed in a list and the ratio of the number of data items of the target data corresponding to each index item. ,
The shape, here length, of each index item at the time of index display together with the data list display is calculated and obtained. That is, when the index items are displayed during the index display, the index items are displayed according to the length corresponding to the number of data corresponding to the index items (step A7).

A scroll bar is displayed adjacent to the index display, and a dragger is displayed at a position corresponding to the designated data position in the scroll bar (step A).
8). In the initial state, the designated data position indicates the beginning of all data, and the input unit 2
When the specific data is specified by the operation 1, it is assumed that the specified data position is stored in the memory 26 as the specified data 26g.

When the setting of the indexed scroll bar is completed, the CPU 20 sequentially displays the data of the range to be displayed on each line in the list display screen (step A9), and also displays the data corresponding to the designated data position. (Specified data) is highlighted (step A1)
0).

Further, the CPU 20 sets the index item including the designated data in the index display to the normal display, shades the other index items (step A11), and determines which index item the designated data corresponds to. Make it easy to understand.

FIG. 4A shows an example of a list display of data to which an indexed scroll bar is added. The example shown in FIG. 4A shows a case where “Tsukue” is selected as the designated data. In this case, since the specified data is included in the “ta row”, the index item “ta” is normally displayed during the index display,
Index items other than the index item "ta" are shaded. In the scroll bar, a dragger is displayed at a position corresponding to the index item "ta", that is, at a position of designated data in all data. That is, since each length of the index item matches the number of corresponding data, the position of the dragger matches the position of the index item corresponding to the specified data.

Here, when the position designation for displaying the list is input from the input unit 21, the CPU 20 executes each processing corresponding to the designated position (step A12).
First, when a position designation for selecting specific data from a plurality of data displayed in a list is input (step A1)
3) The CPU 20 calls and displays the contents of the designated data from the database 26b (step A1).
4). For example, continuous position specification (so-called double click, double tap, etc.) for specific data at short intervals.
In the following, this is referred to as "double designation".
20 causes the display unit 22 to display detailed data on the designated data registered in the database 26b in association with the data displayed in the list, instead of displaying the list. Thus, the search for the target data in the database 26b ends.

When the dragger in the scroll bar is dragged in the data list display (step A15), the CPU 20 detects data corresponding to the dragger position changed by the drag operation (step A16). The detected data is set as designated data (step A17).

In this case, in the same manner as described above, the data range including the designated data is set as a list display target, and a scroll bar and an index display corresponding to the list display are performed (steps A8 to A11). Thus, by performing a drag operation on the dragger, a list of data at an arbitrary position (range) in all data can be displayed.

On the other hand, when the index item of the index display is designated in the data list display (hereinafter, referred to as single designation) (step A18), the CP
U20 detects data corresponding to the head of the designated index item (step A19), and sets the detected data as designated data (step A17).

In this case, in the same manner as described above, the data range including the head data of the designated index item is set as a list display target, and a scroll bar and an index display corresponding to the list display are performed (steps A8 to A1).
1). Thus, by arbitrarily selecting and instructing the index item being displayed in the index, it is possible to display a list of data corresponding to the specified index item.

When the index item being displayed in the index is double-designated (step A20),
The CPU 20 proceeds to the sub-index processing shown in the flowchart of FIG.

First, in the sub index processing, the CPU
20 acquires the number of data items in the designated index item by referring to the database 26b (step A2).
1). Further, the CPU 20 acquires the sub-index item data to add the sub-index display to the data list display (step A2). For example, when the sub-index processing is executed by double specification for the index item “ta”, the CPU 20
Sub-index items "ta""chi""tsu""te" included in the index item "ta" from the database 26b
“And” is acquired as sub-index item data, and is stored in the memory 26 as a sub-index item 26e. Then, the sub index item is set to the head (“ta”) as initial data (step A23).

The CPU 20 determines the number of data items corresponding to the target sub-index (here, “ta”) in the database 2.
6b, and stored in the memory 26 as the number of data items 26f per sub-index item for each sub-index item (step A24).

When the next sub-index item is stored as the sub-index item 26e (step A25), the CPU 20 sets the target sub-index item to the next sub-index item (step A26), and similarly. The number of data items corresponding to the target sub-index item (here, "chi") is acquired by referring to the database 26b, and stored in the memory 26 as the number of data items 26f for each sub-index item (step A24). Similarly, each sub-index item stored as the sub-index item 26e is sequentially set as a target sub-index, the number of data items corresponding to each sub-index item is acquired, and stored as the number of data items 26f for each sub-index item (step A).
24-A26).

When the number of data items corresponding to all the sub index items is obtained, the CPU 20
Is based on the number of data items included in the specified index item and the ratio of the number of data items of the target data corresponding to each sub-index item. Here, the length is calculated and obtained. That is, when the sub-index items are displayed during the sub-index display, the sub-index items are respectively displayed with a length corresponding to the number of data corresponding to the sub-index items (step A27).

A scroll bar is displayed adjacent to the sub index display, and a dragger is displayed at a position corresponding to the designated data position in the scroll bar (step A28). In the initial state, the specified data position indicates the head of the data included in the specified index item. If the specific data is specified by the operation of the input unit 21 with respect to the list display in the past, It is assumed that this designated data position is stored in the memory 26 as designated data 26g.

When the setting of the sub-indexed scroll bar is completed, the CPU 20 sequentially displays the data in the range to be displayed on each line in the list display screen (step A29) and corresponds to the designated data position. The data (designated data) is highlighted (step A30).

Further, the CPU 20 sets the normal display of the sub-index item including the designated data in the sub-index display and shades the other sub-index items (step A31), and assigns the designated data to any of the sub-index items. Make it easy to see if it is true.

FIG. 4B shows an example of a list display of data to which a scroll bar with a sub index is added. The example shown in FIG. 4B shows a case where “Tsukue” is selected as the designated data. in this case,
Since the specified data is included in the sub-index item "tsu", the sub-index item "tsu" is normally displayed during the sub-index display, and the sub-index items other than the sub-index item "tsu" are shaded. I have. In the scroll bar, the dragger is displayed at the position corresponding to the sub-index item “T”, that is, at the position of the designated data in all data included in the designated index item. In other words, since each length of the sub-index item matches the number of corresponding data, the position of the dragger matches the position of the sub-index item corresponding to the specified data.

Here, when the position designation for displaying the list is input from the input unit 21, the CPU 20 executes each processing corresponding to the designated position (step A32).
First, when a position designation for selecting specific data from a plurality of data displayed in a list is input (step A3)
3) The CPU 20 calls and displays the contents of the designated data from the database 26b (step A3).
4). Here, for example, when there is a double designation for specific data, the CPU 20 replaces the detailed data on the designated data registered in the database 26b in association with the data displayed in the list with the list display. It is displayed on the display unit 22. Thus, the search for the target data in the database 26b ends.

When the dragger in the scroll bar is dragged in the data list display (step A35), the CPU 20 detects data corresponding to the position of the dragger changed by the drag operation (step A36). The detected data is set as designated data (step A37), and an index item for the detected data is set as a designated index (step A38).

In this case, in the same manner as described above, the data range including the specified data is set as the target of the list display, and the scroll bar corresponding to the list display and the sub-index corresponding to the specified index are displayed (steps A28 to A3).
1). Thus, by performing a drag operation on the dragger, a list of data at an arbitrary position (range) in the data included in the specific index item can be displayed. When the sub-index display is performed, the number of data represented by the entire length of the scroll bar corresponds to the data corresponding to only one index item, and thus the number of data corresponding to the scroll bar shown in FIG. Less than. That is, FIG.
Even if the dragger is dragged by the same amount on the scroll bar in the list display of FIG. 4B, the change range of the data range to be displayed in the list is smaller in the case of the list display of FIG. Therefore, a drag operation for displaying a list of desired data is facilitated.

On the other hand, when the sub-index item of the sub-index display is single designated in the data list display (step A39), the CPU 20 detects the data corresponding to the head of the designated sub-index item (step A40). The detected data is set as designated data (step A37), and an index item for the detected data is set as a designated index (step A38).

In this case, in the same manner as described above, a data range including the head data of the designated sub-index item is set as a list display target, and a scroll bar and a sub-index display corresponding to the list display are performed (step A2).
8-A31). Thus, by arbitrarily selecting and instructing the sub-index item in the sub-index display, data corresponding to the specified sub-index item can be displayed in a list.

When the sub-index item being displayed in the sub-index is double designated (step A4)
1), the CPU 20 returns to the process of step A8 shown in the flowchart of FIG. 2 and displays a list of the entire data.

As described above, in the information processing apparatus according to the first embodiment, the index items of the index display are displayed with a length (shape) corresponding to the number of data items corresponding to each index item. The position of desired data in the data can be roughly grasped, and can be used as a guide for the operation of the dragger on the scroll bar for specifying the desired data.
In addition, by double-designating an index item, a scroll bar can be displayed together with a detailed sub-index display in which the specified index item is further subdivided, so that an operation for displaying a list of desired data is easier. Can be

Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram showing a configuration of an electronic circuit of the information processing device 12 according to the second embodiment of the present invention.
The information processing device 12 is configured by a computer which reads programs recorded on various storage media and whose operation is controlled by the read programs.

Information processing apparatus 12 in the second embodiment
In the case where data to be displayed is composed of long text data such as memo data of an electronic organizer or electronic book data (digitized character data), an arbitrary range is set. In addition to a scroll bar operated by the user for display, a function is provided for displaying an index based on an item break extracted from data to be displayed.

As shown in FIG. 5, the information processing device 12
The CPU 20 is interconnected with the input unit 21, the display unit 22, the communication unit 23, the storage device 24, and the memory 28.
Note that the input unit 21, the display unit 22, the communication unit 23, and the storage device 24 have the same functions as those in the first embodiment described above, and detailed descriptions thereof will be omitted.

The CPU 20 controls the overall operation of the information processing apparatus 12, and executes various processes by executing programs stored in the memory 26. CPU2
0 indicates that the scroll bar program 26a stored in the memory 26 is to be executed, so that the data registered in the database 26b by the execution of the data display program 28b is displayed and the scroll bar processing with an index is described (details will be described later). Can be performed.

The memory 26 stores information on programs and data accessed by the CPU 20 as necessary. In this embodiment, in addition to the scroll bar program 28a and the data display program 28b, search word candidate data 28c, Various data such as the current search word 28d, the display target data 28e, the total number of lines 28f of the display target data, the search result word data 28g, the search result word 28h, and the line position 28k of the search result word are stored.
The memory 28 is provided with a work area for temporarily storing work data, if necessary.

Next, the operation of the information processing apparatus according to the second embodiment will be described. First, when an instruction to display the display target data 28 e (a series of text data such as a document) stored in the memory 28 is input from the input unit 21, the CPU 20 causes the data display program 28 b stored in the memory 26 to operate. To start the process of displaying the specified data. Further, the CPU 20 controls the scroll bar program 28 so that the range of data to be displayed can be easily changed in accordance with an instruction from the user.
By executing a, a search index display process is executed.

FIG. 6 is a flowchart showing a search index process executed when text data such as a document is designated as a display target. Hereinafter, the search index processing will be described with reference to the flowchart shown in FIG.

First, the CPU 20 reads text data designated as a display target (step B1),
The total number of lines 28f of the display target data is stored in the memory 28, and a search word determination process is performed on the text data (step B2). In the search word determination process,
This is processing for setting words to be extracted as index items in search index display from data to be displayed.

FIG. 7 shows a flowchart of the search word determination processing. In the search word determination process, if the search word used last time is registered in the search word candidate data 28c, it is read out (step C1). The search word candidate data 28c includes, for example, as shown in FIG. 8A, words previously registered as search words by the user, of which the last used word indicating that the word has been used in the previous search word determination process. Data is registered. Here, when the search word does not need to be changed (step C2), the CPU 20 registers the corresponding search word in the current search word 28d (step C7), and registers the corresponding search word in the search word candidate data 28c. Is set for the previous use (step C8).

On the other hand, when the search word needs to be changed, the user is caused to specify the search word to be used this time. Here, another candidate registered in the search word candidate data 28c in advance can be selected, or a new search word can be input.

Here, when selecting from other candidates registered in the search word candidate data 28c, the CPU 20
Displays the search word registered in the search word candidate data 28c on the display unit 22 and allows the user to select it. The CPU 20 registers the selected search word in the current search word 28d (step C7), and sets previous use data for the corresponding search word registered in the search word candidate data 28c (step C7).
8).

On the other hand, when a new search word is input, the CPU 20 registers the character string input by operating the input unit 21 as the search word in the search word candidate data 28c (step C6). In this search word input, not only a simple character string but also a character string including a wild card used in general character string search, etc. It can be input (step C5). For example, the search word "Chapter?"
("?" Is a wildcard)
The words of "Chapter 1", "Chapter 2" ... are designated as search words. In addition, "(?)"
, "(1)", "(2)" ...,
Words such as “(a)”, “(b)”, “(1)”, “(2)”, etc. are designated as search words.

The CPU 20 registers the input word in the search word candidate data 28c and also registers it in the current search word 28d (step C6).

When the search word is determined by the search coral determination processing, the CPU 20 sets a pointer at the head of the display target data to manage the processing target position (step B3). Further, the CPU 20 acquires the total number of lines of the display target data (step B4).

The CPU 20 reads out data to be searched for a search word from the data to be displayed, that is, data in the row indicated by the pointer to be searched (step B).
5) While searching the position of this data row, search for the search word registered in the current search word 28d is performed (step B6).

If the search word has been found (step B7), the CPU 20 stores the searched search result word as a search result word 28h, and stores the line position counted in step B6 in the search result word. It is stored as the word line position 28k (step B8).

When there is data at the position next to the pointer (step B9), the CPU 20 sets the pointer to the next position, and searches for the search word for the display target data at the position indicated by the pointer in the same manner as described above. (Steps B5 to B8). By executing this for all the display target data, the search result words 28h corresponding to the search words and the row positions 28k of the search result words corresponding to the respective search words are stored in the search result word data 28g.

FIG. 8B shows the search result word data 28.
An example of the search result word 28h registered in g and the row position 28k of the search result word is shown. The example shown in FIG. 8B is a case where “Chapter? Chapter” is designated as a search word, and “Chapter 1”, “Chapter 2”... “Chapter 5” are registered as search result words, The extracted line positions of each word are registered in association with each other.

When the search for the data to be displayed is completed, the CPU 20 determines the index length of each search word (index) from the row position of the search word with respect to the total number of data lines (step B11). That is, when performing index display together with the display target data, the shape (length) when displaying the index item is determined according to the data amount of each range divided by the search word (index).

When determining the index length for displaying each index item, the CPU 20 displays an index on, for example, the right side of an area in the display screen on which the display target data is displayed, and sets a scroll bar adjacent to the index display. Display. In the index display, the search result words registered in the search result words 28h are used as index items, and are displayed with index lengths corresponding to the respective data amounts. In addition, the items other than the index items corresponding to the current display range are highlighted and displayed, so that the user can easily understand the display range of the currently displayed data. The position of the dragger on the scroll bar adjacent to the index display is also displayed at a position corresponding to the display range. In other words, since each length of the index item matches the corresponding data amount, the position of the dragger matches the position of the index item.

FIG. 9 shows an example in which an index display and a scroll bar are displayed together with the display target data. This example shows a state in which the vicinity of the end of the data corresponding to the search result word of “Chapter 3” (just before the search result word “Chapter 4”) is displayed. As shown in FIG. 9, the search result words “Chapter 1”, “Chapter 2”... “Chapter 5” extracted from the display target data are used as index items, and the length of the index items corresponds to the corresponding data amount. It has a length according to. The position of the dragger on the scroll bar is also displayed at the position corresponding to the index item.

As described above, in the information processing apparatus according to the second embodiment, in the search word determination processing, a word extracted from the display target data based on the search word specified by the user is used as an index item. Can be performed. Therefore, index display can be added to character data such as a document regardless of the type of data. Also, since the index items of the index display are displayed by the length (shape) corresponding to the data amount corresponding to each index item, the position of the desired data in all the data can be roughly grasped. It can be used as a guide for the dragger's operation on the scroll bar for specifying the data to be performed.

In each of the above-described embodiments, the scroll bar and the index display (sub-index display) are provided on the right side of the data display area. However, they may be provided at any of the upper, lower, left, and right positions. . in this case,
For example, a scroll bar or an index display is provided at a position corresponding to the data arrangement direction. Although the scroll bar and the index display are provided adjacent to each other, it is preferable that the scroll bar and the index display be adjacent to each other in operation, but they may be provided separately.
