Abstract

PURPOSE:To correct a hand written character on paper to which the character is inputted by recognizing and inputting a code for correcting the hand written character and using an input editing means updating the position, order and corrected result of an input document memory. CONSTITUTION:A character written in the paper set up on a tablet surface of an input device 1 is sent to a recognition part 2 as the pen point coordinate data of a stroke and registered to an input decument memory 4. If a character correcting code is inputted from said paper, an recognition part 2 trasnfers the code and position to an input editing part 3. The additional information of the correct result is applied to the character concerned in the input document memory 4. After deciding the output sequence of the output of the input decument memory 4 on the basis of the position of the input document memory 4, address column 10a of an additional information column 10 and the information of a corrected result column 10b, the data are outputted from the input document memory 4.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Description of the field to which the invention pertains The present invention relates to editing of input characters in a two-handwritten character input method.

(2) Description of conventional technology The configuration of the conventional handwritten character input method is as shown in Fig. 1) To modify two characters, press the correction function key while looking at the display displaying the recognition result. (Kodaka et al., "Online handwritten character recognition device", Transactions of the Institute of Electronics and Communication Engineers, Vol. J65 D, A
8, 1982) 0 For this reason.

When inserting or deleting characters, the correction position is specified on the display, and the inserted characters are entered on the tablet, which has the drawback of complicated operations and the need for a display.

(3) Purpose of the Invention The present invention provides nine means for recognizing handwritten document correction symbols;
Means for registering the position, order, and correction results of recognized characters and document correction symbols in the input document memory; and 2. Input editing for updating the position, order, and correction results of the input document memory by inputting the document correction symbols and symbols. (4) Description of structure and operation of the invention FIG. 2 is an actual example of the present invention, 1 is an input device that reads handwritten characters and symbols for document correction.

2 is a character and character correction symbol recognition unit; 3 is an input editing unit that registers and edits input characters and document correction symbols; 4 is an input document memory that registers codes of input and recognized characters; be.

Further, 5 is a display section that displays characters from the input editing section.

6 is an output unit that outputs characters from the input editing unit to a printer;
711-i: A document file that stores characters from the input editing section.

Next, details of the present invention will be explained with reference to FIGS. 2 and 3. Place paper on the tablet surface of input device 1,
When you write down the characters to be entered on the paper.

The characters are transferred to the recognition unit 2 as stroke pen point coordinate data. The recognition unit 2 cuts out and recognizes two characters. 2% as a character recognition method, Gansho 53-15399
9, and Japanese Patent Application No. 54-061146 are suitable.

The recognized character code is registered in the input document memory 4 with the written position and order information added thereto. That is, input characters as shown in FIG. 3 (α-1) are recognized,
It is registered in the input document memory in the format shown in FIG. 3(b-1). The input document memory shown in FIG. 3 (b=1) is one embodiment of the input document memory 4, and has a configuration in which input positions and correction results are associated with character codes. Note that 8 is the character position field, 9 is the character code field, and 10 is the attached information a.
+10a shows the address field, and 10b shows the correction result field.

Next, when a character correction symbol as shown in FIG. 3 (α-2) is input, the recognition unit 2 recognizes each correction symbol and transfers the symbol code and position to the input editing unit 3. do.

Document correction symbols entered by handwriting include insertion, deletion, end of inserted character string, etc., and an example of the pattern is shown in FIG. 3 (α-2). In the figure, 11 is a deletion symbol, 12 is an insertion symbol, and 13 is an end symbol of the inserted character string. Add symbols for document correction as necessary.

The input editing section 3 adds attached information of the correction result to the corresponding character in the input document memory 4 according to the document correction symbol from the recognition section 2. In Figure 3 (a-2), the input character "no"
When the deletion symbol "-" is completely written above the
2) Attachment information for deletion is added to the correction result column iob of position 3 "no".

Next, in FIG. 3 (α-2), when the insertion symbol "△" is written before the input character "Ko" and the insertion character "Device" is inputted, the insertion symbol is first recognized by the recognition unit 2. It is recognized and the insertion code and position are transferred to the input editing section 3. The input editing section 3 temporarily stores the character immediately before the inserted symbol. Next, when the character code and position of the insertion character "device" is transferred,
In the input editing section 3, following the document correction symbol (using the input order, that is, the input order), the input editing section 3 enters the address 1Qiloa in the attached information column of the character immediately before the insertion position as the start position of the insertion character. Add address information, and add information about inserted characters to the inserted character correction result column iob,
Furthermore, the position information of the character following the inserted character is added to the address column of the end character of the inserted character.

When outputting the input document memory 4, the input editing section 3 determines the output order based on the position of the input document memory 4, the address in the attached information field 10, and the modification result information, and outputs the determined output order. Third
In the output of the input document memory shown in FIG. 6-2, deletion is instructed in the attached information column of "no" in the 5th place heart-3, so it is not output. Furthermore, since the address of the inserted character (position 11) is registered in the attached information M of "Riki" after "Riki" at position 5, "Sou" is output next to "Riki".

As a result of the above, the output data from the input editing section 3 is shown in Figure 3 (
The character string shown in c-2) is obtained. By having such a means, it is possible to correct characters on paper on which two handwritten inputs are being made.

Note that the characters output from the input editing section 3 are displayed on the display section 5. The output unit 6 can display and output to a printer, and can also be registered in a two-document file 7.

Next, when outputting the characters in the input document memory to the output foil manufacturing 6 via the input editing section 3, the data in the input document memory 4 is updated to correspond to the output position of the printer, as shown in FIG. . Accordingly.

By setting the output paper of the printer on the tablet of the input device 1, the document can be corrected by handwriting symbols and characters for document correction on the paper using the method described above.

(5) Description of Effects As explained above, the present invention recognizes handwritten characters and document correction symbols, and inputs the positions, order, and correction results of recognized characters and document correction symbols into a document memory. 1. By having an input editing means for updating the position, order, and correction results of the input document memory by inputting symbols and characters for document correction, 2. Correcting characters on paper on which handwritten input is being performed. It can be carried out.
