Abstract

PURPOSE:To educate a user so as to master correct stroke order by displaying the stroke order of a character user and the result of a comparison with the correct stroke order. CONSTITUTION:When a handwritten character is inputted from an input means 101, a character recognizing means 102 recognizes the inputted handwritten character. The stroke order of the inputted handwritten character is stored in a 1st storage means 103. Then a comparing means 105 reads the correct stroke order of the character that the character recognizing means 102 recognizes out of a 2nd storage means 104 and compares with the stroke order of the inputted handwritten character and a display means 106 displays the comparison result. Then a stroke order check part judges that the character is written in the correct stroke order when the comparison result indicates the coincidence or in wrong stroke order when not, and displays the difference in stroke order to let the user know it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character processing device for recognizing characters input by handwriting and performing various processes.

[0002]

2. Description of the Related Art Conventionally, in this type of character processing device,
No matter what stroke order characters are input, only the font is recognized and processed.

[0003]

Therefore, even if the user makes a mistake in the stroke order when inputting characters, the character is recognized as a correct character if the font is correct, so the user does not notice the mistake in the stroke order and the stroke order is correct. It may be misunderstood as if.

The present invention has been made in consideration of such circumstances, and provides a character processing device with a handwriting input function capable of teaching a user the correct stroke order of input characters.

[0005]

FIG. 1 is a block diagram showing the basic configuration of the present invention. In the present invention, an input means 101 for inputting handwritten characters and a character recognition means 102 for recognizing the input handwritten characters. A first storage means 103 for storing the stroke order of input handwritten characters, a second storage means 104 for storing a correct stroke order in advance, and a character recognition means 102.
The second storage means 1 stores the correct stroke order corresponding to the characters recognized by
Comparing means 105 for comparing the stroke order of handwritten characters read out from 04 and input, and display means 1 for displaying the comparison result.
A character processing device provided with 06 is provided.

A tablet device is preferably used for the input means 101 and the display means 106. A CPU is used for the character recognition means 101 and the comparison means 105, a ROM is used for the second storage means 104, and a first storage means 1 is used.
A RAM can be used for 03. A CRT or a liquid crystal display may be used as the display unit 106.

[0007]

In FIG. 1, when a handwritten character is input from the input means 101, the character recognition means 102 recognizes the input handwritten character. The stroke order of the input handwritten characters is stored in the first storage unit 103.

The comparing means 105 is the character recognizing means 1
The correct stroke order of the characters recognized by 02 is stored in the second storage means 104.
Compared with the stroke order of the handwritten characters read from and input. The display means 106 displays the comparison result.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. This does not limit the invention.

FIG. 2 is a configuration diagram for realizing the present invention. Reference numeral 1 is a tablet device, and reference numerals 2, 3 and 4 are input frames for inputting handwritten characters. Reference numeral 5 denotes an input pen. Handwritten characters can be input by inputting handwriting in the input frames 2, 3 and 4 with this pen.

Reference numeral 6 is a control unit for processing input characters, and 7
Is a handwriting character recognition unit that recognizes handwritten characters input by the user, 8 is a writing order checking unit that checks the writing order, 9 is a writing order pattern storage unit that stores each input pattern of the handwriting recognized characters, and 10 is a handwriting recognition character The correct stroke order storage unit 11 stores the correct stroke order, and a stroke order save memory 11 temporarily saves the stroke order of handwritten characters input by the user.

Next, the case of recognizing the input character "right" will be described. FIG. 3 shows a “right” stroke order pattern string stored in the stroke order pattern storage unit 9. Pattern 2
The order of 1, 22, 23, 24, 25 is the correct stroke order,
Each stroke order pattern is stroke order code 26, 27, 2
I have 8, 29, 30.

FIG. 5 shows the correct right-hand stroke order code string stored in the correct stroke-order storage unit 10, 41, 42, 4
It has 3,44,45 information. Here, 51 in FIG.
Assuming that "right" is written in the wrong stroke order as shown in .about.55, the stroke order memory 61 saves a sequence of stroke order codes 61 to 65 as shown in FIG.

Here, the stroke order pattern 51 matches the pattern 22 in the stroke order pattern storage unit 9, and the stroke order code “2” is taken out from the code 27 and saved in the code 61 in the stroke order save memory 11. .

Next, the stroke order pattern 52 is the pattern 21.
And the stroke order code “1” is extracted from the code 26 and saved in the code 62. Similarly, when a stroke order code is obtained for the stroke order patterns 53, 54, 55 and saved in the codes 63, 64, 65, the result becomes as shown in FIG.

Next, the handwriting recognition section 7 recognizes "right" from the stroke order pattern as shown in FIG. 6 written by the user of the stroke order pattern storage section 9.

Next, the stroke order check unit 8 compares FIG. 5, which is the correct “right” stroke order code string, with FIG. 7, which is the stroke order code string written by the user, and if they match, write in the correct stroke order. If they do not match, it is determined that they were written in the wrong stroke order.

Through the above processing, it is possible to judge whether the stroke order of the handwritten characters written by the user is correct or incorrect. If the stroke order is incorrect, the stroke error is displayed on the tablet device 1 to inform the user. Then, the correct stroke order as shown in FIG. 4 is displayed in order by the patterns 31, 32, 33, 34, 35. Thereby, the user can correctly learn the stroke order of the characters.

[0019]

According to the present invention, since the result of comparison between the stroke order of characters entered by the user and the correct stroke order is displayed,
The user can be taught the correct stroke order.
