Abstract

PURPOSE:To use newly defined, easy to write handwritten editing command codes without mixing up with other codes by extracting features of editing command codes and checking propriety as editing command codes. CONSTITUTION:Codes such as insertion, deletion, copying or shifting are inputted as handwritten editing command from a code registering and inputting section 10, and features of the handwritten editing command are extracted by a feature extracting section 11. A registration propriety checking section 12 checks whether the editing command codes can be identified from other handwritten editing command codes or not. In the case where identification is possible, the feature extracted data are registered in a registering section 13. In the stage of edition, the registered command is used as command for edition. Thus, a user can use newly defined, easy to write handwritten editing command codes without mixing up with other codes.

Description

[Detailed Description of the Invention] [Summary] The present invention relates to a handwriting editing device, and particularly to a handwriting editing device in which a user determines a handwritten editing command in order to reduce rejection or misrecognition of editing command input due to differences in writing style depending on the person. ,
To provide a handwritten editing device that can be registered.

In the present invention, first, a symbol such as an insertion symbol, a deletion symbol, a copy symbol, or a movement symbol is input as a handwritten editing command from the symbol registration input section, and the feature extraction section inputs the handwritten f,
l Extract the features of the command symbol. Then, the registration validity checking section checks whether the editing command symbol can be distinguished from other handwritten editing command symbols, and if the editing command symbol can be distinguished, the data from which the characteristics have been extracted are registered in the registration section. At the editing stage, this registered command can be used as an editing command.

As a result, the handwritten editing command can be input efficiently even if the writing style differs depending on the person.

[Industrial application field]

The present invention relates to a handwriting input device, and in particular, to a handwriting editing device that allows a user to register easy-to-use editing commands in order to solve the difficulty of inputting editing commands due to differences in writing style depending on the person. .

[Traditional technique]

There is an online handwritten character recognition device as a device for inputting Japanese documents. Online handwritten character recognition involves writing characters on a tablet using a writing pen, recognizing the written characters with a recognition processing unit, converting them into properly arranged characters, and displaying the characters.

When creating a document, it is naturally necessary to perform editing processes such as deletion, insertion, copying, and movement. In such editing processing, editing commands corresponding to deletion, insertion, copying, and movement are input, but in this case as well, handwritten editing in which commands are entered by hand is possible in the same way as inputting characters. In conventional handwritten editing devices, only predetermined command symbols can be used when inputting editing commands by handwriting.

Therefore, although handwritten editing devices are considered important because they allow text to be edited without the need for complicated keyboard operations like in word processors, conventional technology does not allow users to input editing commands. However, due to the user's writing style, the editing command could not be matched with the registered editing command, and the editing command could not be accepted.

[Problem that the invention seeks to solve]

Conventional handwritten S-moon wave collectors can only accept predetermined command symbols, which has caused a problem in that it is extremely difficult for some users to input editing commands due to different writing styles.

[Means for solving problems]

In FIG. 1, it has a handwritten edit command input section 5 and a handwritten edit command symbol registration section 7, and after the input handwritten edit command is recognized by the handwritten edit command recognition section 6, according to this handwritten edit command, The document editing section 8 edits the document.

The handwritten editing command symbol registration unit shown in FIG. 2 includes a handwritten editing command symbol registration input unit 10 for registering and inputting handwritten editing commands such as deletion, insertion, copying, and movement, and features of the input handwritten editing commands. A feature extraction unit 11 performs extraction, and a registration validity check unit 12 checks whether the feature data extracted by the feature extraction unit 11 is distinguishable from other handwritten editing command symbols. The system includes a registration section 13 that registers the feature data extracted by the feature extraction section 11.

[For production]

According to the present invention, the user can change editing commands such as deletion, insertion, copying, and movement into easy-to-write symbols, thereby reducing recognition failures and errors due to differences in the writing style of editing command symbols.

〔Example〕

Next, the handwritten editing device of the present invention will be explained with reference to the drawings.

FIG. 1 μ is a configuration diagram of a handwritten editing device of the present invention.

A text is input from a document data input section 1 and once stored in a document data storage section 2. Document data is transferred from the document data storage section 2 to the document editing section 8, where it is deleted, inserted, copied,
Editing such as movement is performed, but in that case, in addition to the document data, the handwritten characters input from the handwritten character input unit 3 are recognized by the handwritten character recognition unit 4, and the recognized characters are designated in the text. It is inserted at the specified position, or newly added and edited. The edited document is displayed on the display section 9.

In the present invention, like characters, editing commands are also input by hand and recognized.

Here, the handwritten editing command is input from the handwritten editing command input section 5. Then, the symbol of the handwritten edit command inputted by the handwritten edit/collection command recognition section 6 is compared with the symbol from the handwritten edit command symbol registration section 7 for recognition. The recognized result is transferred to the document editing section 8 as a handwritten editing command, and the text is edited by deleting, inserting, copying, or moving the text according to the command. The result of editing the text is sent from the text editing section 8 again to the document data storage section 2 and stored therein.

Again, the text data output from the document data storage section 2 is edited by the document editing section 8 according to the handwritten editing command, and the process is repeated until a correct text is completed. During execution of this process, the text is sent from the document editing section 8 to the display section 9, and the text being edited is always displayed.

In the present invention, editing commands can be registered in the handwritten editing command symbol registration section 7 as symbols that are easy for the user to use.

For example, FIG. 4 shows an example of a handwritten editing command.

Handwritten editing commands include those essential for editing deletion symbols, insertion symbols, copy symbols, movement symbols, and the like.

Figure 4 (al) shows handwritten editing command symbols given by the system. The deletion symbol is a horizontal line on the character to be deleted, and the insertion symbol represents the V character where it should be inserted. Also, for copying "" indicates the part to be copied, followed by "
” is expressed by moving the characters and inserting the V character. In addition, the moving J symbol indicates the part of the character that should be moved, and the character within that [] should be moved and inserted.
expressed in characters. Here, since the movement symbol [ ] is often misrecognized, if the user wants to change it to (), the user registers it in the handwritten editing command symbol registration section 7. After this, the handwritten editing command symbols will be as shown in FIG. Therefore, according to the present invention, it is possible to eliminate the difficulty in inputting editing commands due to the fact that the writing style differs depending on the person.

As shown in FIG. 1, the handwritten editing command symbol registration unit 7 performs feature extraction on the handwritten editing command symbols of each year, so that the input handwritten editing command symbols can be distinguished from other handwritten editing commands. A check will be made to see if That is, in the handwritten editing device of the present invention, deletion,
A handwritten editing command symbol registration input unit 10 that inputs handwritten editing commands such as insert, copy, and move, and a feature extraction unit 1 that extracts features of the input handwritten editing commands.
1, a registration validity check unit 12 that checks whether the feature data extracted by the feature extraction unit 11 can be distinguished from feature data of other handwritten editing command symbols;
It is comprised of a registration section 13 that registers the feature data extracted by the feature extraction section 11 when the identification is possible. This allows the user to freely define editing commands, and enables efficient input of handwritten editing commands.

Furthermore, in the present invention, when a handwritten editing command is registered and input, features are extracted for the registered and inputted handwritten editing command to check its validity, so that the command is not distinguishable from other commands. do not have.

Next, the flow of processing of the handwritten editing device of the present invention will be explained using FIG.

In the handwritten editing device of the present invention, when processing starts, STI is first used to check whether the text data is a new file. If it is a new file, there is no text yet, so handwritten characters are input from the handwritten character input section 3 (Sr1). And Sr.
3, the handwritten character recognition unit 4 recognizes the input handwritten characters. The recognized result is once stored in the text data storage section 2 as text data.

In addition, in STI, if the file is not a new file but an old file, that is, text has already been stored in the file, text data is input from the text data input section 1 (
Sr4). The input text data is stored in the document data storage section 2.

The text data stored in the document data storage section 2 is sent to the document editing section 8 (Sr5), and the text is edited. In this case, editing commands such as a deletion symbol, an insertion symbol, a copy symbol, or a movement symbol are used, so these editing commands are input in Sr6. Edit commands are input from a handwritten edit command input section 5 and recognized by a handwritten edit command recognition section 6. This is the process of Sr7.

The handwritten edit command recognition unit 6 has already registered the input handwritten edit command in the handwritten edit command symbol registration unit 7.
Match with the handwritten editing command registered in , and perform LW X&. In this case, check whether the symbol of the handwritten editing command is the correct symbol (Sr
1). If the symbol is correct, the correct editing command is sent to the text editing section 8, and one of deletion, insertion, copying, and movement is executed to edit the text. Then, in order to input the next command, the process returns to Sr6 and the operation is repeated.

In Sr1, if the input handwritten editing command is an incorrect symbol, the process moves to Sr1.

At Sr1, the user is asked whether to perform command registration processing. If it is not registered, the process returns to Sr6 again, the next editing command is input, and the same process is repeated.

When registering an editing command, the process moves to 5TIO. Then, the user selects the editing content of the input handwritten editing command, that is, whether it is a deletion symbol, an insertion symbol, or a symbol for copying or moving.

In 5T11, the editing symbol is entered, and in 5T12, the characteristics of the symbol of the handwritten editing command that has been registered and input are extracted. Feature extraction is performed by the feature extraction unit 11, and the extracted feature data is checked at 5T13 to see if it is valid as a command symbol. Checking and checking the validity of 5T13 is done by the registration validity checking section 1 in Figure 2.
It is executed in 2. As a result of checking, if it is found that the symbol has the same characteristics as other symbols and cannot be identified, so that registration is not valid, return to 5TII and enter a different editing symbol again by handwriting the editing command symbol registration input unit 10. You will have to fill it out. Then, feature extraction is performed, and validity is checked using 5TI3.

If the registration validity check unit 12 finds that the handwritten editing command can be distinguished from other handwritten editing commands,
The input editing command symbol is registered in the registration unit 13 according to the process of 5T14.

Then, the registered editing command is used as a new handwritten editing command in the editing processing of Sr5 by returning the processing to ST6.

〔Effect of the invention〕

In the present invention, as described above, the characteristics of the input editing command symbol are extracted and checked to see if it is valid as an editing command symbol. Therefore, the user can select the newly defined handwritten editing command symbol that is easy to write. It can be used without being confused with other symbols. Therefore, according to the present invention, it is possible to smoothly input handwritten editing commands.
