Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for determining correctness of handwritten input patterns such as handwritten characters and handwritten figures.

[0002]

2. Description of the Related Art When teaching "characters" to a child for the first time, while the parent shows the picture book and read it, at the same time, take the child's hand about how to write the "characters" representing the animals, vehicles, etc. The conventional way of teaching "characters" is to teach them one by one, or for teachers to give "aiueo" etc. on the blackboard one by one while giving attention to the number of strokes, character shape, stroke order, etc.

[0003]

[Problems to be Solved by the Invention] However, when a parent teaches, even if the character is "hiragana", the parent himself does not always acquire the correct stroke order, and the wrong stroke order that he remembered as a child is retained. There are many examples of teaching to one's own child. In addition, when a parent teaches an infant who has a strong desire for knowledge, it is often difficult in time to teach the child, and it is often the case that the child's requirements cannot be fully met. In the case of such an infant with a strong desire for knowledge, a device that allows you to rewrite it by simulating the "hiragana" that represents animals and vehicles in picture books etc. Sometimes I try to remember it myself. In such a case, the stroke order is often completely wrong, and as a result the stroke count is incorrect and the glyph itself can not be remembered, so the parents and teachers have to correct it later. No, sometimes you have a hard time fixing a wrong habit. In the case of a child with a strong desire for knowledge like this, the child can practice the "characters" by himself and judge right or wrong the number of strokes of the character written by the child, the stroke order, the character shape, etc. on the spot to find out what was wrong. It can be said that all of the above problems will be solved with the aid of learning tools.

[0004]

In order to solve the above-mentioned problems, the present invention comprises a handwriting input device, a display device, a storage means, etc., and an input pattern written on the handwriting input device is stored in the storage means in advance. By comparing and analyzing with the stored standard pattern, the correctness determination is comprehensively performed, and the determination result is displayed on the display device together with the written input pattern. Further, this handwritten input pattern is a handwritten character, and this handwritten character is compared and analyzed with the correct stroke count, stroke order, character shape, etc. of the character stored in advance in the storage means, and the correctness determination is comprehensively performed. The judgment result is displayed on the display device together with the written character, and at the same time, the correct character and the handwritten character are overlapped and displayed, and each of them is color-coded for each stroke according to the stroke order.

[0005]

According to the above means, when the correctness determination system imitates a character displayed on the display device and a child writes the character on the handwriting input device, the written character is taken into the correctness determination system as coordinate data, Simultaneously with the reproduction on the display device, the correctness determination system collates the character recognition dictionary data stored in the storage means with the correct stroke number, stroke order, character shape, etc. of the character, compares and analyzes them, and displays them on the display device. The judgment result is displayed.

Embodiments of the present invention will now be described with reference to the accompanying drawings. FIG. 1 is a hardware configuration diagram of a handwriting input pattern correctness determination system of the present invention, and FIG. 2 is a system configuration diagram of the same. As shown in the figure, the handwriting input pattern correctness determination system 1 includes a system body 2, a handwriting input tablet 3, a monitor TV 4, and the like. System body 2
Includes a keyboard 5 having various switches for input on the upper surface, a CPU 6 for moving the entire system, a cassette tape recorder 7 and the like inside, and a system cartridge 8 storing software for moving the entire system,
Cassette tape 9 storing learning program, voice, kanji data, etc. described later, learning result, that is, judgment result (result)
An IC card 10 or the like for storing information such as is freely attachable.

The handwriting input device 3 is provided with a touch panel 11 on its upper surface, and handwriting input patterns such as "kana", "kanji", and "graphics" input from the touch panel 11 are
CPU (one-chip type) 1 converted into digital data by A / D converter 13 via I / F 12
4 is recognized as a character or a figure. In addition, the coordinates of these characters or figures are SIO (serial input / output) 15
Then, the parallel data is converted into serial data and transmitted from the CPU 14 to the CPU 6 of the system main body 2 via the buffer 16. Reference numeral 17 is an address decoder, which is the CPU 14 of the input tablet 3 having a small capacity.
In addition, bank switching is performed to access a later-described character identification dictionary having a large capacity stored in the ROM 18. The RAM 19 is used as a work area for data input from the touch panel 11.

Next, on the touch panel 11 of the above system,
A method of recognizing a pattern input by handwriting and determining whether it is correct or incorrect will be described by taking Kanji as an example. All kanji or common kanji (1945) that are frequently used in everyday life are decomposed into one of the 37 stroke sets shown in FIG. 3 according to the stroke of each stroke of the kanji. It is stored in the character identification dictionary in the ROM 18. For example, the model “right” kanji is displayed on the screen of the monitor TV 4, while the child displays the “right” character on the touch panel 11 in the stroke order from 20 to 20 as shown in FIG. When written, it is sent to the CPU 6 of the system main body 2 as coordinate data by the above-mentioned SIO 15, and is displayed side by side on the screen of the monitor television 4 along with the “right” character of the model, in line with the stroke. This handwritten “right” character is extracted as a stroke indicated by 21 in FIG. 4 for each stroke drawn by the child (for example, counted as one stroke when the child pen downs), and this stroke 20 is extracted as shown in FIG. The “right” character 23 stroke 24 stored in the character identification dictionary 22 in the ROM 18 is collated, compared, and analyzed to be recognized as the “right” character 25.
In the character identification dictionary 22, "right" 23 and "left" in FIG.
As shown in FIG. 26, similar Kanji characters are grouped based on the bias, the stroke, the crown, and the like, and collation and comparison with similar Kanji characters are also performed.

Next, how to determine whether the written character is correct will be described. The kanji is stored in the character identification dictionary with the correct stroke number and stroke order of this kanji as T1 to T5, as shown in "Right" 27 given as an example in FIG.
When the child inputs, for example, the number of strokes such as S1 to S5 of 28 and the stroke order, the correct stroke order T1 to T5 as shown in the table of FIG.
And the corresponding stroke order S1 to S5 are compared and compared to determine whether the stroke count and the stroke order are correct. The lengths of the strokes S1 to S5 are calculated based on the "right" coordinate data input at this time, and the shape, direction, angle, and manner of intersection of the written characters, as well as the volume, straw, and crown. Positional relations such as the above are collated, and each part is evaluated and graded, and then a graded evaluation is comprehensively calculated to determine whether or not the shape is correct. Specifically, the correct character shape, the accepted character shape, and the rejected character that is not recognized as the designated character are scored as patterns in advance and stored in the character identification dictionary. Patterns are compared and compared, and for example, a pattern of xx points or more is determined as a correct character shape. In addition, when determining the character shape, check for tome, splash, harai, tsuku, hanare, and missing. Also, the rewrite is treated as an abnormal glyph.

As described above, based on the result of sequentially checking whether the number of strokes is correct, the stroke order is correct, and the character shape is correct, the kanji input by handwriting is comprehensively judged as correct. The result of the correctness determination is displayed on the display device 4, and at the same time, the correct character and the handwritten character are overlapped and displayed, and each character is color-coded for each stroke according to the stroke order.

Next, a method of advancing learning by the handwriting input pattern correctness determination system of the present invention will be described with reference to the flowcharts of FIGS. Learning of kana, kanji, and figures can be done in almost the same procedure. When the power is turned on, an instruction for selecting learning contents is first displayed on the screen of the monitor TV 4. Touch the date on the touch panel 11
Enter from. Next, select one of the letters (Hiragana etc.) that you want to learn by dividing it into numbers, and the letters in the block and the words and pictures using those letters will appear on the screen.
At the same time, those letters are audibly indicated by the cassette tape 9. According to the selected block, the first character is copied on the touch panel 11 by imitating the model character shown on the monitor TV 4 (trace writing) (STEP 1). At this time, the characters printed on the sheet placed on the touch panel 11 are traced and written. If you press the predetermined judgment key on the touch panel 11 after writing, if the written character is wrong (STEP
2), proceed to STEP 6 described later.

If the answer is correct in STEP2, the message of the judgment result is immediately displayed on the display device 4 by the above-described procedure together with the sound effect indicating the correct answer (STEP3), and at the same time, the message such as tome, honey, harai, tsuku, hanare, and missing is displayed. If there is a caution (STEP4), the content is displayed (STEP4).
5). These points of caution are given when the written character is correct at the very limit of the passing score. If there is no caution in STEP 4, the process proceeds to STEP 11 described later.

When the handwritten input (STEP1) is incorrect (STEP2), the first incorrect message is output together with the sound effect indicating the incorrect answer (STEP6). At this time, the correct characters and the characters input by handwriting are displayed in different colors according to the stroke order, so that it is clear what is wrong. Pay attention to the mistakes and touch panel 11
If the correct answer (STEP8) is reached by pressing the judgment key again, the correct answer message (STEP3) is output together with the sound effect indicating the correct answer. In the case of an incorrect answer, as in the case of the first answer, a second incorrect answer message is issued (STEP 9), and the model is displayed on the monitor television 4 (STEP 10). If you select re-learning (S
The process returns to TEP11) and STEP1 and waits for input. If you write by tracing this example, it will be displayed on the monitor TV 4 in real time. Here, if re-learning is not selected in STEP 11, the process ends.

Without tracing the example (STEP 12), write on the touch panel 11 (STEP 13)
In the case of EP14), the incorrect message as described above is issued (STEP15), and the model is displayed again, but if re-learning is not selected (STEP16), the process ends.
If the answer is correct in STEP 14, a message for correct answer is displayed (STEP 17), and if there is no caution (STEP 18), either YES or NO of re-learning is selected as described above. If there is a caution such as tome, splash, hail, tsuku, hanare, or missing (STEP 18), that effect is displayed (STEP 19), and if STEP 16 of re-learning is selected, the process returns to STEP 13 and waits for input.

In addition to the above-mentioned special keys, a review key for displaying the strokes of characters written by oneself in real time, a model key for displaying the model strokes, etc. are prepared in advance to be used at any time during learning. Be prepared to go back and practice repeatedly. The results of learning by using these various keys according to the instructions displayed on the screen of the monitor TV 4 are all stored in the system main body 2 and compared with the next learning,
You can measure the progress of learning. This record can also be stored in the individual IC card 10.
