Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a list display device in an information processing device capable of color display such as CD-I.

[0002]

2. Description of the Related Art In recent years, when searching information, etc., a list of lists is often viewed, and an increasing number of children and adults use information processing devices such as electronic books to search dictionaries and encyclopedias. ing. When checking the list list, to check where the displayed list item is in the total number of items, check the total number of pages by displaying the page number and the position by checking the displayed page. There was a method to check the position, and a method to check the approximate position by the scroll bar in the list box. In addition, when returning to an item that was once viewed, the user had to remember the number of pages and the position of the scroll box before operating.

[0003]

However, in the above-mentioned conventional configuration, it is difficult for a child or an unfamiliar person to handle because it is difficult to remember such as the number of pages and the position on the line when checking. However, there was a problem that the operation was not fun.

The present invention solves the above-mentioned problems of the prior art, and has excellent operability in which it is possible to easily return to an item to be checked in a survey such as an encyclopedia and a color corresponding to a display ratio of a display item. An object of the present invention is to provide a list display device that can be changed to give a feeling of familiarity to the operation.

[0005]

In order to achieve this object, the list display device of the present invention calculates the ratio of the items designated by the user to the whole display, and according to the ratio, a part of the color on the screen is changed. And a condition search unit for selecting a search target from the search information recording medium in which the search target information is input by the input unit, and the condition search unit. An item storage unit that stores the results of the search performed by, a screen control unit that displays a search list in the item storage unit on a CRT, and a ratio of the items displayed on the screen control unit to the total number of search items are displayed in color. And a color display section for displaying the color.

[0006]

With this configuration, the ratio of the items being displayed to the total number of items can be represented by changing the color on the display screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the functions of the information processing apparatus in one embodiment of the present invention.

Reference numerals 1 and 2 are input means including a mouse for selecting a process or a target and a keyboard for inputting characters or selecting a process.

The above-mentioned input means is a central processing unit (CPU).
Part) 5 is connected. The CPU unit 5 is connected to the condition search unit 3, the item storage unit 4, and the screen control unit 6, and controls various processes.

When displaying the search results in a list from the search information recording medium 8 in which the information to be searched is input, the condition search unit 3 selects from the search information recording medium 8 an item that matches the condition input by the user. Perform processing.

The item storage unit 4 reads the result retrieved by the condition retrieval unit 3 from the retrieval information recording medium 8 and stores it.

The screen control unit 6 is connected to the color display unit 7 to display a list of search result list items. When the user presses the next page key or the previous page key, the search result list display item is pressed. Turn over each page with the key
While scrolling the list, the color of the function key corresponding part is changed every 20% in order to inform the user what percentage of the total number of search items the displayed items are.

The color display section 7 displays a list of lists and function keys whose colors change.

In one embodiment of the present invention, the search target disk 8 contains a modern Japanese dictionary in a format that allows a prefix match search.

The operation of the list display device configured as described above will be described with reference to FIGS. 2 to 5.

FIG. 2 is a flow chart showing the processing steps of the present invention, FIG. 3 is data in the item storage section in one embodiment of the present invention, and FIG. 4 is a display of the list display device in one embodiment of the present invention. FIG. 5 is a screen, and FIG. 5 is a diagram showing how the screen changes when the ratio of the number of displayed items to the total number of items changes in one embodiment of the present invention.

First, a case will be described as an example in which the user attempts to search for a word prefixed with "hon" (prefix match search) from a modern Japanese dictionary using the search target disk. When the user inputs the search character "hon", in step a, the condition search unit checks whether there is a word prefixed with "hon" from the search target disk,
When there is a matching item in step b, the CPU unit stores the search result in the item storage unit in step c (see FIG. 3). If there is no matching item in step b, the process ends without displaying. Then step d
At, the screen control unit displays a list of condition matching items (see FIG. 4).

In step e, when the display change is instructed by the user by the next page key or scroll, in step f, the ratio (display item%) of the display items designated by the CPU section to the total number of items is calculated.

For example, the word prefixed with "hon" is 153
When words are searched, up to 8 words can be displayed in one screen of the list, so 153/8 = 19 remainders 1 and the total number of displayed pages is 20, so the function key color changes every 20%. If you do, the color changes every 4 pages.

In step g, it is checked whether the displayed item% changes from the previous display% in the 20% frame, and if there is a change, in step h, the screen control unit causes the function key to be pressed. Change the color of the key part of (see Figure 5).

For example, (b) From page 2 to page 4, since it is 20% or less, the previous page key of the first block of the function key portion is blue.

(C) 20% to 40% from page 5 to page 8
Therefore, the previous page key and the next page up to the second block of the function key portion are made green.

(D) 40% to 60 from page 9 to 12
%, The front page key, the next page key, and the third function key up to the third block of the function key portion are colored yellow.

(E) From page 13 to page 16, 60% to 8
Since it is 0%, the previous page key, the next page key, the third function key and the return key up to the fourth block of the function key portion are made red.

As the user presses the next page key to display 8 words from "honcho [main tone]" as shown in FIG. 5, since it corresponds to the 12th page, the 40% to 60% portion is displayed. Display the function key by changing the color of the 3 blocks to yellow.

In this embodiment, for the sake of simple explanation, 20
I changed the color every%, but by still changing the color finely, the fun of the color change, and remembering the color of the place checked before, when returning to that place, if you return to that color Since there is a checked part in a part of the corresponding list screen, accuracy will be improved.

[0028]

As described above, according to the present invention, which side of the total number of items the item being displayed is represented by the color and the filled width of the function key, and when there is an item to be checked, By remembering the color and returning to the block of that color, you can easily return to the item you want to check, the operability is good, and the color changes according to the display ratio of the display item etc. By expressing the ratio by the color that is most sensuously memorable by humans, the aim is to create a familiar man-machine interface.
