This conventional character practice device displays selected model characters on the screen of the tablet panel, and also displays written characters input by tracing the model characters on the panel surface, superimposing them on the model characters. Display on screen.

In this case, there is no limit to the number of times you can practice like when using paper, and since the model character and the written character are displayed on the screen overlapping each other, you can compare the two characters and see how their strokes overlap. This clearly shows the difference between the two characters, allowing for effective calligraphy.

[Problem to be solved by the invention]

In the case of the conventional character practice device, the writing pressure of the model characters and written characters is not taken into account at all.

As a result, they are unable to learn the correct way to apply pen pressure, which is important in order to write truly beautiful characters, and there is a problem in that they are unable to perform ideal calligraphy, including how to apply pressure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a character practice device that allows ideal calligraphy, including how to apply pen pressure, using a tablet.

[Means to solve the problem]

In order to achieve the above object, the character practice device of the present invention includes a model character data output section that outputs display data of model characters whose width of each stroke changes according to pen pressure; display data is supplied to display the model character on the panel surface, and output coordinate data and pen pressure data of each writing position based on the tracing of the model character on the panel surface. outputting to the tablet display data of a written character whose position and width change according to the writing position of the tracing calligraphy and the writing pressure based on the coordinate data and the writing pressure data; and a handwritten character data output unit that displays handwritten characters on a screen.

[Effect]

In the case of the character practice device of the present invention configured as described above,
Based on the model character display data output from the model character data output section, model characters in which the width of each stroke changes depending on the pen pressure are displayed on the screen on the panel surface of the tablet.

Furthermore, when you trace the model character on the panel surface, the tablet outputs the coordinate data of the writing position as well as the pen pressure data, and based on both data, the written character data output section outputs the same data as the display data of the model character. Display data of handwritten characters is formed based on the tracing.

The display data of the handwritten characters is then supplied to the tablet, and the handwritten characters are displayed superimposed on the model characters.

It can be done.

〔Example〕

One embodiment will be described with reference to FIGS. 1 to 8.

Figure 1 shows an integrated display/input tablet, which consists of a tablet with a liquid crystal panel, Model No. 5P-300 or 5P-301 manufactured by Wacom Co., Ltd., which can obtain pen pressure data as well as coordinate data, and is placed on a desk, etc. flat body (1a
) and a writing stylus pen (1b),
On the top of the main body (1a) is a liquid crystal panel surface for display and input (
IC) is provided.

Figure 2 shows an operation/processing device (2) formed by a computer device that is separate or integrated (built-in) with the tablet (1), and (3) is a written data input section into which data from the tablet (1) is input. , (4) is the written character data output section, (
5) is a function selection section, (6) is an instruction character specification section, (7) is a model character search section, (8) is a specified character data output section, (9
) is a model character data output section, ``Yu'' is a DP matching processing section, and ``Ren'' is a score data output section. -"In the case of this embodiment, the calligraphy function includes not only the function of tracing the model characters displayed on the screen, but also the function of displaying the model characters after writing and scoring the written characters (hereinafter referred to as the third function). ) is also provided.

It has a first function of tracing and writing, and a second function of simultaneously displaying all strokes of a model character and causing tracing.

When in use, each of the above functions is selectively selected by key operations in the function selection section (5), and kanji, hiragana, Roman letters, and numbers are selected by key operations in the specified character setting section (6). One or more characters for calligraphy are selected from various characters such as .

Now, suppose that the first function is selected and four kanji characters, ``bun'', ``ji'', ``hand'', and ``hon'' are selected as calligraphy characters, then the function selection section (5) The selection result is notified to the model character data output section (9).

Furthermore, based on the designation of the designated character setting section (6), text display data of the four designated kanji characters is supplied from the designated character data output section (8) to the tablet (1), and this display data is used as shown in FIG. As shown in the figure, there are four writing input frames (12a), (12b), (12) on the panel surface (IC).
c).

At the top of (12d), each of the four kanji characters to be learned is displayed in so-called full-width characters.

Further, from the instruction character setting section (6) to the model character search section (7),
) is notified of the four kanji, and based on this notification, the model character search unit (7) searches for the corresponding data from pattern display data (image data) of various model characters held in memory etc. .

By the way, the pattern display data of each model character consists of broken line pattern data in which the width (thickness) of each stroke changes depending on the pen pressure.

Then, the model character search unit (7) sends the pattern display data of the four searched kanji to the model character data output unit (9).
supply to.

Based on this supply and the selection of the function selection section (5), when the first function is selected, the model character data output section (9) first selects the first model character data to be displayed in the leftmost input section α). The pattern display data of the first stroke of the stroke order of the character "Bun" is supplied to the tablet (1).

Due to this supply, initially the fourth
The first stroke of the first model character "bun" shown in FIG. 3(a) is displayed as a broken line.

Then, when the displayed first stroke is traced with the pen (1b), it is sent from the tablet (1) to the written character data output part (4) via the written data input part (3) at the set minute time interval. Coordinate data and pen pressure data of each measurement point are supplied as position information of the tracing.

Based on the supply of both data, the written character data output section (
4) As shown in Figure 5, each measurement point is defined as a circle (P) with a radius corresponding to the pen pressure data, and each day (P) is surrounded by a tangent line.
Form the pattern display data of the first stroke of the written character whose width changes according to the pen pressure data similar to the pattern display data of the model character, and display this display data on the tablet (]
).

Then, the first stroke drawn as shown in FIG. 4(b) is displayed as a solid line in the input frame (12a).

Furthermore, when the tracing of the first stroke is completed, the pattern display data of the second stroke of the model character "bun" is output from the model character data output section (9) based on the end command from the pen (1b), timer operation, etc. is output, as shown in Figure 4 (C
), the second stroke of the model character "bun" is also displayed in the input frame (12a).

Then, when the displayed second stroke is traced with the pen (1b), the written character data output unit (4) forms pattern display data of the second stroke of the written character in the same manner as described above, and this display data is Based on Figure 4(d)
A second stroke drawn as shown in is also displayed.

Furthermore, when the tracing of the second stroke is completed, the third stroke of the model character "sentence j" is also displayed, as shown in FIG. 4(e).

After tracing all the strokes of the model character "sentence J", the model character (12d) in the next input frame (12b) is completed.
The display and tracing of each stroke is also performed for the model characters "hand J, r book".

By the way, regarding the overlapping portion between the model character and the written character, the degree of overlapping is clearly displayed by, for example, a change in gradation.

Also, for example, repeat learning using a pen (1b).

By commanding changes in learning and learning characters, you can practice various characters over and over again.

Then, the model character and the written character are displayed superimposed and can be compared. At this time, the width of each stroke of both characters changes depending on the writing pressure, so the difference in writing pressure is clearly shown, which is ideal. Can perform calligraphy.

Next, when the second function is selected by the function selection section (5), based on the notification from the selection section (5), the model character data output section (9) is different from when the first function was selected. , for each model character, output pattern display data for all strokes at the same time.

Therefore, for example, as shown in FIG. 6(a), all strokes of the model character "bun" are displayed simultaneously in the input frame (12a).

Then, by tracing all the displayed strokes, all the strokes of the written characters are displayed in the order of writing, as shown in No. 6 [21(b)].

In the case of this second function, as in the case of the first function, calligraphy can be performed by tracing in consideration of pen pressure.

Next, when the third function is selected by the function selection section (5), based on the notification from the selection section (5), the model character data output section (9) receives a termination command from, for example, the pen (1b). The pattern display data will not be output until the

Therefore, as shown in FIG. 7(a), for example, the input frame (1
In 2a), no model characters are initially displayed.

Then, when the character "sentence" to be learned specified at the top of the input frame (12a) is written in the input frame (12m'%) with the pen (1b), the written character data output section The pattern display data of the handwritten characters is output from (4), and the handwritten characters are first displayed in solid lines in the input frame (12a), as shown in FIG. 7(b).

Furthermore, upon input of the end command, the pattern display data of the model character "sentence J" is output from the model character data output section (9), and the pattern display data of the model character "sentence J" is displayed in the input frame (12a) as shown in FIG. 7(C). The character "Bun" is displayed as a broken line over the written character.

The coordinate data and pen pressure data of the model characters and written characters are also supplied to the P matching processing unit αO), and when the third function is selected, processing is performed based on the notification from the function selection unit (5). The next DP matching process is performed by section α0).

That is, the DP matching processing unit (10) samples each feature point, such as the start point and end point of each stroke, and each measurement point at each set interval, for the model character and the written character.

Furthermore, each sampled feature point is surrounded by a tangent line, and the eighth
As shown in figures (a) and (b), the model characters,
Comparison patterns (e) and (n) of written characters are formed.

Then, the distance difference between both patterns -9(n) and the writing pressure difference based on the difference in the size of each feature point are determined, and the comparison scale is changed and added to both differences, and the addition result is sent to the score data output section αυ supply to.

Based on this supply, the score data output section αυ has an upper limit of 10
Score display data of the score result with 0 points is generated and supplied to the tablet (1), and the score is displayed at the bottom of the input frame (12a) where the writing is completed, as shown in FIG. 7(C).

Since the pattern matching process is performed taking into account not only the pattern deviation of the trace drawn from the distance difference but also the pen pressure, the degree of deviation is the same in Figures 8 (a) and (b).
), based on the difference in pen pressure, the score in (a) is higher than that in (b).

Therefore, when the third function is selected, the first and second
Unlike the function of , it is possible to perform calligraphy taking into account the pressure of the pen without showing a model character in advance, and moreover, the score display after writing takes into account the pressure of the pen, so that an accurate evaluation can be shown.

And at least the first. Of course, it can be applied to cases where only one of the second functions is provided.

Furthermore, it goes without saying that the tablet may be of a type other than a liquid crystal display, and the model characters and the handwritten characters may be displayed in different colors.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

Using a display/input integrated tablet that outputs coordinate data and pen pressure data, the width of each stroke changes according to the pen pressure based on the display data of the model characters output from the model character data output section. The model character to be written is displayed on the screen of the tablet panel, and by tracing the model character on the panel surface, the tablet outputs the writing pressure data along with the coordinate data of the writing position, and based on both data, the written character data output section Thus, display data of the handwritten character based on the tracing is formed, which is similar to the display data of the model character.

Then, the display data of the written characters is supplied to the tablet, and the written characters are displayed over the model characters, and the writing pressure of both characters is determined by the difference in the width (thickness) of each stroke of the model characters and the written characters. Since the difference between the two characters is also shown, it is possible to provide an electronic character practice device that can perform ideal calligraphy taking into consideration pen pressure, which was not possible in the past.
