Description

[Detailed Description of the Invention] [Summary] This is a character practice machine mainly aimed at young children, and can timely determine whether an input handwritten character pattern is acceptable or not by tracing a displayed model character pattern.

[Industrial application field]

The present invention relates to a character practice machine, which is a type of computer-based learning device, and is used for practicing how to write two characters.

To practice writing using a character practice machine, model character patterns are first presented to the practitioner on the display.

This is written by tracing and the workmanship is evaluated or determined whether it is acceptable or not, but especially in a character practice machine aimed at young children, it is important to inform the practitioner in a timely manner whether or not it is acceptable. be.

In this case, it is desired to provide a character practice machine that can timely point out to IF* learners the parts of their writing that are not good.

[Conventional technology]

FIG. 3 is a block diagram showing the configuration of a conventional example of a character practice machine.

Reference numeral 1 denotes an instruction unit, such as a keyboard input device, for selecting and instructing a character type to be practiced.

2 shows model character patterns for each character type to be practiced.
While writing at a standard speed, for example, in the form of coordinate values of multiple points obtained every 0.1 seconds, each stroke is memorized in the order of the serial number given to the stroke order, and the one instructed by the instruction section 1 is output. character pattern generator.

3 is a first pattern buffer that stores a character pattern for one character extracted from the character pattern generating section 2;

4 is a display section that displays character patterns.

5 is a display control unit that controls the display of the display unit 4;

Reference numeral 6 denotes an input unit 3, such as a tablet, which reads and inputs the coordinate values of points relative to the handwritten character pattern inputted by tracing the character pattern displayed on the display unit 4, for example, every 0.1 seconds.

7 is a second pattern buffer that stores the handwritten character pattern input by the input unit 4;

8 by techniques such as pattern matching.

Evaluation for evaluating the quality of the handwritten character pattern input by the input unit 6 and stored in the second pattern buffer 7 stroke by stroke or as a whole by comparing it with the model character pattern stored in the first pattern buffer 3 Department.

[Problem that the invention seeks to solve]

In character practice machines with the above configuration, especially those aimed at young learners, evaluation results are not given to the practitioner until one or all strokes have been written, so it is difficult to identify areas where the writing style is poor. There is a problem in that it is not possible to point out to practitioners in a timely manner.

[Means for solving problems]

The present invention includes a pattern buffer that stores model character patterns to be practiced as coordinate values of a plurality of points arranged in stroke order at predetermined intervals, a display section that displays a nine-character pattern, and a display section that displays a nine-character pattern. an input section that reads and inputs coordinate values of points on a handwritten character pattern inputted by tracing a model character pattern at predetermined intervals; The above-mentioned problem is solved by including a corresponding point determining section that determines the presence or absence of a corresponding point on the model character pattern corresponding to the inputted point based on the distance to the memorized point.

[Effect]

That is, by first specifying a character to be practiced using the instruction section 1, the pattern is stored in the pattern buffer 3 and displayed on the display section 4 at the same time.

Next, have the practitioner write a character, for example 0 from the input section 6.
．． For each point on the handwritten character pattern that is input every second, corresponding points are found from among the points stored in the pattern buffer 3, with the distance between them being less than or equal to a predetermined darkness value.

As a result, when corresponding points are obtained, the points on the input handwritten character pattern are connected with straight lines in the input order and displayed using, for example, a polygonal line.

Also, if no corresponding points are obtained, that is, if the handwritten character deviates significantly from the model character pattern by more than a threshold value.

■Do not display the above-mentioned polygonal lines.■Display polygonal lines in different display colors.■Sound a buzzer, etc., to timely point out to the practitioner the points of poor writing style.

〔Example〕

Hereinafter, the gist of the present invention will be specifically explained using examples.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and FIG. 3 shows the same reference numerals as the conventional example.

9a, 9b, 9c and 9d are model characters corresponding to one point input from the input unit 6, depending on the distance between the one point on the handwritten character pattern input by the input unit 6 and the point stored in the pattern buffer 3. This is a component of the corresponding point determining unit 9 that determines corresponding points on a pattern.

9a is a first register that temporarily stores the coordinate value of one point input from the input unit 6;

9b is a second register that temporarily stores the serial number of the corresponding points obtained last time.

9c is among the points stored in pattern buffer 2.

A third register stores the coordinate values of, for example, three points in the stroke order following the corresponding point stored in the second register 9b, together with each serial number.

9d determines the point closest to the point stored in the first register 9a and the distance therebetween from among the three points stored in the third register 9c, and determines that the distance exceeds the darkness value stored in advance. A distance determination unit that determines whether or not.

Reference numeral 10 denotes a display control unit that performs control to display on the display unit 4 the model character pattern read out from the pattern generation unit 2 and the pattern determined by the determination result in the corresponding point determination unit 9.

In the above configuration, it is assumed that the processing speed in the corresponding point determination section 9 and other parts is sufficiently faster than the input speed of the two-manpower section 6 (for example, one point every 0.1 seconds).

Letter practice is carried out as follows.

<a) First, by inputting a character code from the instruction section 1, a model character pattern of the character to be practiced is read from the pattern generation section 2, stored in the pattern buffer 3, and displayed on the display section 4 at the same time. do. Note that the second register 9b is set to zero as an initial value.

(b) Have the user trace the model character pattern displayed on the display unit 4.

(C) When the coordinate value of one point on one handwritten character pattern is stored in the first register 9a from the input unit 6.

From the model character pattern stored in the pattern buffer 3, the number stored in the second register 9b, that is, the coordinate values of the first to third points after zero, are read out and stored in the third register 9c. be done.

(d) The distance determination unit 9d determines the point closest to the point stored in the first register 9a and the distance therebetween from among the three points stored in the third register 9c, and the distance determined is determined in advance. If the built-in darkness value is not exceeded, the point is displayed in the normal display color on the display section 4 via the display control section 10, and the number of the point is displayed in the second register 9.
Set to b.

Further, if the determined distance exceeds the threshold value, the point is displayed on the display section 4 in a different color from the normal display color, for example, red, via the 1 display control section 10.

(e) Subsequently, when the coordinate value of the next point on one handwritten character pattern is stored in the first register 9a, the coordinate value of the next point on one handwritten character pattern is stored in the second register 9b from among the model character patterns stored in the pattern buffer 3. The coordinate values of the three points in the stroke order following the number given are read out and set in the third register 9c.

(f) The distance determining unit 9d determines the point closest to the point stored in the first register 9a and the distance therebetween from among the three points stored in the third register 9c, and the distance determined is determined in advance. If the built-in darkness value is not exceeded, the line segment connecting that point and the previously determined point is displayed on the display section 4 in the normal display color via the display control section 10, and the number of that point is displayed. is set in the second register 9b.

Further, if the determined distance exceeds the darkness value, the line segment connecting that point and the previously determined point is displayed on the display section 4 in red, for example, via the 1 display control section 10.

Thereafter, in the same manner, as illustrated in FIG. 2, a model character pattern as shown by the solid line is displayed on the display section 3, and tracing is performed as shown by the 9-dotted line until it reaches the point ■ and reaches the 9-point l. Assume that the corresponding point corresponding to is T1.

If the point input next to f is Bi, the distance between Bi and the three points following TI on the model character pattern <72, T3, T4 is calculated, and if the minimum value does not exceed the darkness value and B are connected by a solid line, and if the minimum value exceeds the dark value, the area between ■ and 1 is displayed in red, for example.

〔Effect of the invention〕

As explained above, according to the present invention, the parts of the writing style that are not good are pointed out to the practitioner in a timely manner, so that the practitioner can reliably know the parts that are not well written.
