Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to word processors and the like, and more particularly to an input command method that allows easy manual input of commands required when creating a document.

〔overview〕

When creating a document or inputting characters using a word processor, personal computer, etc., processes such as deleting or inserting documents or characters, or opening frames may be performed. In such a case, it is necessary to specify a command such as deletion or insertion of a document and a position on the document at which the command is to be executed at the same time on the touch panel.

To specify the above position, for example, specify the position of the document that requires deletion or insertion by placing a finger or the like on the position of the document displayed on the touch panel, and to specify the content of the command, delete or insert at the above position. The designation is made by writing a predetermined shape (pattern) that corresponds to a command such as "."

However, as the number of types of commands increases and the number of patterns preset according to the contents of the commands also increases, it becomes difficult to input commands.

Even when defining patterns corresponding to instruction contents, the present invention makes the mutually corresponding instruction contents the same pattern, and by making the writing directions (strokes) of the patterns different, it is possible to easily input instructions even if there are multiple instructions. It is something that makes it possible.

(Prior Art) In word processors, microcomputers, etc., the user inputs various commands such as deleting and inserting characters and sentences, opening frames, etc. when creating a document or displaying a document. When issuing a command, for example, use the keyboard or mouse to specify the position in the document where the deletion or insertion should be performed and the contents of the command such as deletion or insertion.For example, specify the position in the document where the command should be executed. The specification of is the specification of what line and character position on the display,
The specification of the command content is the specification of specific command content such as deletion or insertion of characters, opening of a frame, etc.

However, inputting commands to a word processor or the like in two steps as described above is extremely inefficient in terms of operating efficiency of a keyboard or the like. For this reason, in order to improve the operability of conventional manual commands, a command input method is known in which the command position and command content can be specified at the same time by simply drawing a specific shape on a touch panel with a finger (Japanese Patent Laid-Open No. 1983-1999-1). 256023), this method specifies the command execution position by placing a finger or the like on the document position where the command is desired to be executed, and then draws a simple predefined pattern at that position corresponding to the command content. By specifying the instruction content, the instruction position and instruction content can be specified at the same time.

[Problem to be solved by the invention]

Although the command input method described above is certainly effective in terms of operability, the operator must memorize multiple patterns in advance along with the command contents. It becomes difficult to use command input methods such as

Further, although it is possible to write the contents of the command and the pattern in a memo or the like, the user must refer to the memo or the like every time a command is input, making it impossible to operate efficiently.

In view of this, it seems possible to use some method to associate command contents and patterns so that more command contents can be input with fewer operation patterns.

An object of the present invention is to enable more commands to be input without increasing the number of patterns.

[Means to solve the problem]

The means of the present invention are as follows.

Transparent touch human input means 1 (see the functional block diagram of the present invention in FIG. 1, hereinafter the same) has a transparent touch operation surface on a display screen for displaying documents, such as a liquid crystal display panel.

The storage means 2 changes the direction of the touch operation on the transparent touch input means 1 for commands 72 that are related to each other, such as designation of the next page or previous page, designation of the next candidate or previous candidate, etc. Stores multiple pieces of pattern data.

The command reading control means 3 reads, from the storage means 2, a command corresponding to the pattern data operated by, for example, a finger, and the touch operation direction of the pattern to the transparent touch input means 1.

The command processing means 4 executes processes such as specifying the next page, previous page, next candidate, previous candidate, deleting or inserting a document, opening a frame, etc., according to the contents of the command output from the command reading control means 3. .

[For production]

The operation of the means of the invention is as follows.

The storage means 2 stores commands necessary for document creation, such as next page, previous page, next candidate, previous candidate, delete, insert, etc., and corresponding patterns, as well as the next page, previous page, and next candidate. Instructions that are related to each other, such as the previous candidate and the previous candidate, are stored as the same type of pattern data, and data indicating that the writing directions are different is also stored. Then, by touching a pattern corresponding to the command content with a finger or the like on the transparent touch input means l corresponding to the position on the display screen where the document for which the command is to be executed is displayed, in a direction corresponding to the command content, The command reading control means 3 searches the storage means 2 from the pattern inputted from the transparent touch input means 1 and the data of its operation direction, reads out the corresponding command, and the command processing means 4 performs processing according to this command.

Therefore, the number of patterns is reduced to approximately half, and more commands can be input without increasing the number of patterns.

〔Example〕

Hereinafter, one embodiment will be described with reference to FIGS. 2 to 7.

FIG. 2 is a perspective view of a word processor to which the command input method of one embodiment is applied. In the figure, an input/display section 7 is provided on the front side of the word processor 6, and behind it is a paper ejection section 8 from which paper on which documents are printed is ejected.
a is formed.

Furthermore, a disk mounting slot 8b for mounting a floppy disk is provided on the side surface of the word processor 6.

The input/display section 7 has a cross-sectional configuration shown in FIG. 3, and a touch panel 10 is disposed in a predetermined space on a liquid crystal display panel 9 in which a liquid crystal agent (not shown) is sealed. The touch panel IO is transparent, and the characters displayed on the liquid crystal display panel 9 can be seen from above through the touch panel IO.

FIG. 4 is a system block diagram showing a control circuit for the human power/display section 7. As shown in FIG. In the figure, the keyboard control section 1
3 outputs a hescan signal to the touch panel 10, reads the output signal also output from the touch panel 10, and determines which position on the touch panel IO is pressed. Further, even when the data of the device constituted by the touch panel 10 gradually moves to form a pattern, the data of the sequentially output positions is similarly detected.

As shown in FIG. 5, the touch panel 10 has, for example, input lines 11a, llb, . . . and output lines 12a, 12b, . . .
A matrix circuit is constructed by providing a switch S at each intersection of 2a, 12b, . . . . The above-mentioned scan signal is supplied from the keyboard control section 13 to the input lines 11a, 11b, . . . at a predetermined timing.
12b... to the keyboard control section I3.

Further, the keyboard control section 13 includes a touch panel 10.
A circuit for preventing chattering that occurs when the switch S is pressed, and a circuit for detecting the end of pressing the switch S are also built in.

On the other hand, the pressed position information on the touch panel 10 obtained by the keyboard control section 13 is output to the input stroke pattern recognition section 14 . Input stroke pattern recognition unit 1
4 recognizes the pattern according to the supplied positional information, and also recognizes the writing direction of the input pattern (the direction of the stroke of the touch operation). Then, the corresponding pattern and stroke direction command stored in the stroke table 15 are read out.

A plurality of patterns and stroke directions of the patterns are stored in advance in the stroke table 15. Then, commands (commands) corresponding to each stroke direction of each pattern are stored (defined).For example, as shown in FIG. direction) is stored as a command to designate the next page, and a reverse stroke of the same pattern \ (direction in which the pattern \ is written from bottom to top) is stored as a command to designate the previous page. Further, as shown in FIG. 3B, the forward stroke of the pattern / is stored as a command to instruct the next candidate, and the reverse stroke of the same pattern is stored as a command to instruct the previous candidate.

Further, as shown in FIG. 1C, the normal stroke of pattern 1 is stored as a command to instruct a line break, and the reverse stroke of the above stroke is stored as a command to instruct a page break, and the pattern shown in FIG. The forward stroke of V is stored as a command to instruct insertion, and the reverse stroke of the same pattern is stored as a command to instruct deletion. That is, as described above, even if the pattern is the same, different commands are stored depending on whether the stroke to the touch panel 10 is positive or negative. However, even if the commands are different, the contents of the commands are related to each other and are easily memorized by the user, such as the next page and previous page in FIG.

Further, the command execution control unit 16 executes a corresponding command according to the command execution instruction signal output from the input stroke pattern recognition unit 14. The liquid crystal display panel 9 displays processing results of the command execution control section 16, errors, etc.

The operation will be explained using the flowchart shown in FIG. 7 when command processing is performed using the command input method having the above configuration.

First, in step 1 (hereinafter referred to as S) to determine whether or not the touch panel 10 has been operated, the touch panel 1
If 0 is operated, it is determined whether the operation is input of pattern data or not (S2). This determination is made by the keyboard control unit 13. For example, if the position indicated by the data output from the touch panel 10 moves and is input as data of consecutive positions, it is determined that the pattern data is manually generated. Further, if the data output from the touch panel 10 is not pattern data, the keyboard control unit 13 outputs this data to a CPU (central processing unit) (not shown), and the CPU executes the corresponding process (S
3).

If the keyboard control unit 13 determines that the pattern data is manually generated, the keyboard control unit I3 outputs the data to the manual stroke pattern recognition unit 14 (S4).

The input stroke pattern recognition unit 14 recognizes the input pattern from the supplied position data and data on the movement direction of the position data, and also recognizes the direction of the stroke, that is, a forward stroke or a reverse stroke. Then, the stroke table 15 is searched to determine whether corresponding pattern data exists (S5). Here, if the corresponding pattern data is not stored, it is determined that the operator has written an incorrect pattern on the touch panel 10, and an error is displayed on the liquid crystal display panel 9 (S5 is N (No), S6). .

On the other hand, the corresponding pattern data is stroke table 1
5 (S5 is Y (yes))
, a corresponding command is read from the stroke table 15 based on the pattern recognized by the input stroke pattern recognition unit 14 and whether the recognized stroke is normal or reverse (S7
). For example, if the input data is a normal stroke pattern, a command to specify the next page is read out as shown in Figure 6(a), and even if the input data is the same pattern, the input data is a reverse stroke pattern. In this case, an instruction specifying the previous page is read. Also, for example, if the input data is a positive stroke pattern ■, see Figure 6 (b).
As shown in , an instruction specifying insertion is read out, and a command specifying deletion is also read out if the manually inputted data is a reverse stroke even in the same pattern (2).

Thereafter, the human stroke pattern recognition unit 14 outputs the command read out as described above to the command execution control unit 16, and the command execution control unit 16 executes processing according to the input command (S8).

In this embodiment, examples of mutually related commands such as next page and previous page, insertion and deletion shown in FIG. 6 are shown, but the data stored in the stroke table 14 is not limited to these examples. do not have.

(Effects of the Invention) According to the present invention, the number of types of patterns for input commands is reduced, and command input can be performed extremely easily.
