Abstract

PURPOSE:To facilitate input operation utilizing a normal character size by displaying a character train in an input area in an enlarged character size until the input of the character train is completed and displaying the character train in the input area in the normal character size when the input is completed. CONSTITUTION:A character input management function 9 sets a next input area on a screen based on screen definition information 10. Character data inputted in keys by a user are written in a text data area 8 via an input buffer 7 and at this time, an attribute is designated as an enlarged-sized character. An echo-back function 12 reflects it to a screen buffer 11 to display the inputted characters in the enlarged-sized character on both sides of a display device 5. When the input of the character data is completed, the character input management function 9 changes an enlarged-sized attribute setting into a normal- sized attribute setting. The input character train displayed in the enlarged character size on the screen of the display device 5 are changed into the normal character size.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input character display method using an enlarged character in an information processing apparatus for facilitating an input operation by displaying a character string key-inputted until it is confirmed.

[0002]

2. Description of the Related Art In an information processing device such as a conventional computer or document creation device, a character input by a key input device is immediately displayed on a display device by an echo back function, but the size of the displayed character is The size is always the one that the user intended and input.

6 (a) and 6 (b) are specific examples thereof, in which 1 is a screen of the display device and 2 is an input area in units of lines, for example. FIG. 6A is an example of input in the standard character size, and the input character string “Kawashima” is displayed in the intended standard character size. In addition, FIG. 6B
Is an example in which the same character string is entered and displayed in an enlarged character size. In these cases, the input character string is echoed back to the input area 2 and displayed immediately after each character is input, and when the input to the input area 2 is completed, the next line is set as the input area. Input is performed in the same manner. Even if the input to the input area 2 is completed, the size of the displayed characters does not change.

[0004]

By the way, it is desirable that the character size of the character data displayed on the display device is as large as possible from the viewpoint of readability, but in general, it can be displayed simultaneously in a limited space on the screen. Due to the compromise with the desire to increase the amount of data, the usual basic display character size is usually not set too large.

Therefore, in the conventional information processing apparatus, when the size of the character intended to be input is a normal character size, the size of the character displayed on the screen by echo back simultaneously with the input becomes relatively small, There is a problem that input errors are likely to occur due to eye fatigue.

An object of the present invention is to provide an input character display method for facilitating an input operation with a normal character size in an information processing apparatus.

[0007]

The present invention enlarges and displays only the character size of a character string being input in the input area in order to achieve the minimum necessary character enlarged display within a limited screen space. , When the input is completed, the original font size is restored.

FIG. 1 is an explanatory view of the principle of the present invention, showing an example method for designating an input area in units of lines. In the figure, 3 is a processing device for editing character data.

Reference numeral 4 is a key input device for inputting character data. Reference numerals 5 and 5'are display devices for displaying character data. 6 is a memory.

An input buffer 7 temporarily holds a character or character string input from the key input device.
Reference numeral 8 is a text data area for storing the input character data.

Reference numeral 9 denotes a character input management function for designating a sequential input area on the screen and storing the character data key-input in the text data area of the memory for management. In the present invention, control for displaying the character data being input in an enlarged size is also performed.

Reference numeral 10 is screen definition information that defines the position of an input area such as a line or item on the screen, which is referred to by the character input management function 9 and is used for setting the input area and managing the display of input character data. It

Reference numeral 11 is a screen buffer for storing dot format data for one screen to be output to the display device 5. The data for one screen is cut out from the text data area 8.

Reference numeral 12 is an echo back function for dot-expanding each time character data input by a key is stored in the text data area 8 and reflecting it in the screen buffer 11.

Numeral 13 is a character string which has already been input and which is normally displayed in character size. Reference numeral 14 is a character string during the input of the enlarged character size display.

[0016]

Operation In FIG. 1, the operation is performed as follows. The character input management function 9 sets the next input area, for example, an input line on the screen based on the screen definition information 10. The character data keyed in by the user is written into the text data area 8 via the input buffer 7, and at this time, the attribute is designated as the character of the enlarged size. Echo back function 1
2 immediately reflects this in the screen buffer 11. As a result, the characters that have been key-in are displayed as enlarged characters on the screen of the display device 5. In this way, the characters sequentially key-in the lines of the input area are displayed on the screen in an enlarged size.

When the input of the character data to the line being input ends due to a line feed instruction or when there is no space left, the character input management function 9 causes the character input management function 9 to store the input character to the current input line stored in the text data area 8. For data, change the enlargement size attribute setting to the normal size attribute setting and set the following line as the input area. As a result, the input character string displayed in the enlarged size on the screen of the display device 5 is changed to the normal character size. The characters 5 and 5'in FIG. An example is shown in which the string "Mizuno" changes to a normal-sized character string when input is complete.

In FIG. 1, the attribute of the input character string can be changed from the enlarged size to the normal size each time the line in the input area changes, but the input area is not in units of lines but in units of items, or in commas, periods, Key input such as shift can be identified and controlled, and when processing such as Kana-Kanji conversion is performed on input character data, when the processing is confirmed, the character size attribute is changed from the enlarged size to the normal size.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. 2A, 2B, and 2C show three embodiments of the input character display method of the present invention from the first to the third. In the figure, the ordinal numbers shown with parentheses using n respectively represent the sequentially defined lines on the screen, and the ordinal numbers 1, 2 and 3 without parentheses are the logic of the input character data respectively. Represents a specific line.

In FIG. 2A, when a physical line and a logical line are continuously associated with each other and the characters of the input line are displayed in an enlarged size, the characters of the upper line or the lower line are temporarily stored. This is an embodiment in which each line is rewritten as normal characters after the input is completed. In the example shown in the figure, after inputting "Kawashima" on the first line, inputting "Mizuno" on the second line with. In this case, the input character string "Mizuno" is displayed in enlarged character size using the first and second lines, and after the input of the second line is completed, "Kawashima" on the first line and "Mizuno" on the second line are displayed. 'Rewrite each in normal character size. Figure 3
2 is a generalized processing flow of the embodiment of FIG.

In FIG. 2 (b), when the screen is defined, the physical lines n, n + 2, ...
This is an embodiment in which the intermediate line is set to a blank line, is not assigned to a logical line, and is used only when displaying in an enlarged character size.

In the embodiment of FIG. 2B, the input character line is displayed in an enlarged size so that other input character lines are not overwritten as in the case of FIG. 2A, but blank spaces are displayed. Since there are many lines, there is a drawback in that the screen usage efficiency is reduced. FIG. 4 is a generalized processing flow of the embodiment of FIG.

FIG. 2 (c) shows a case in which the discrete physical lines are fixed as blank lines by the screen definition in the embodiment of FIG. This is an embodiment in which a line is inserted and a blank line is removed after the input is completed. As in the example shown,
The blank line to be inserted can be one line on the entire screen, but if character data has already been input to the subsequent lines, the process of shifting them downward line by line is required. FIG. 5 is a generalized process flow of the embodiment of FIG.

In each of the embodiments described above, the character size of the input character string is enlarged by taking the input area as a line unit and is returned to the normal size after the end of the input line. It is also possible to easily implement processing as an input area for each item.

In addition, the input area is one character (that is, one digit)
It is treated as a unit, and each time a character is keyed in, that character is displayed in enlarged size, and when the next character is input, the character displayed in the previous enlarged size is returned to the normal character size and is newly input. It is also possible to display enlarged characters in enlarged size. In this case, the method shown in FIGS. 2A to 2C can be used.

Further, in the case of a kana-kanji conversion process for an input character string such as a sentence creation device, the display in the enlarged size can be returned to the display in the normal size when the conversion process is confirmed.

As the enlarged size character pattern,
Any type such as a long body, a flat body, and a double angle can be used.

[0028]

According to the present invention, since only the character string being input is enlarged and displayed, the influence on the screen space can be reduced, the visibility can be improved, and long-time input work can be performed. It is possible to prevent an increase in typographical errors.
