Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing learning device for learning how to write characters and figures.

0002

[Prior Art] Generally, to learn how to write, model characters are printed on a writing notebook, etc., and you practice using that as a reference, or you learn how to write using the model characters printed with dotted lines, etc. I tried to practice by tracing it.

0003

[Problem to be Solved by the Invention] However, it is difficult for an inexperienced person to practice alone from the beginning, and the support of another experienced instructor is required. In particular, it was extremely difficult to memorize the shapes and stroke order of letters accurately. Therefore, it is clear that if characters and figures can be input according to the guide display of the stroke order, even young children will be able to independently and accurately learn how to write letters and figures. An object of the present invention is to enable characters and figures to be input according to a guide display of their stroke order.

0004

[Means for Solving the Problems] The means of the present invention are as follows. The input display section 1 (see the functional block diagram in Fig. 1; the same applies hereinafter) includes a display section 1a that displays characters and graphics, and a display section 1a that displays characters and graphics when the characters and graphics displayed on the display section 1a are traced from above. It consists of a handwriting input section 1b for inputting trajectory data. Note that, for example, the display section 1a is a dot matrix type liquid crystal display device, and the handwriting input section 1b is a transparent touch panel device stacked on top of the display section 1a. The dictionary memory 2 stores the shapes of characters and figures and their stroke order. The display control means 3 reads characters and figures to be learned from the dictionary memory 2, and causes the display section 1a to display the stroke order as a guide. In this case, the display control means 3 may display one stroke of the stroke order blinking to prompt handwriting input, and when tracing the characters or figures displayed on the display section 1a, the part that has been traced will be displayed. The information may be identified and displayed sequentially.

[0005]

[Operation] The operation of the means of the present invention is as follows. Now, it is assumed that the display control means 3 causes the line segments constituting a character to be displayed blinking for each stroke in accordance with the stroke order. For example, if you select the character "ma" as the learning target,
The display control means 3 reads out the character "ma" to be learned from the dictionary memory 2 and displays it on the display section 1a. that time,
The display control means 3 displays the entire character "ma" as a dotted line, for example. In this state, the display control means 3 displays the character "ma".
First, the upper horizontal line is displayed blinking according to the stroke order. Here, the learner selects the handwriting input section 1b from above the blinking display.
When you touch and trace with your finger or pen, the trajectory data is input from the handwriting input section 1b. Next, display control means 3
causes the lower horizontal line that makes up the character ``ma'' to blink. Here, if the learner traces it over the flashing display,
The trajectory data is input from the handwriting input section 1b. Finally, the remaining part of the character "ma" is displayed blinking, and when it is traced, its locus data is input from the handwriting input section 1b. Therefore, characters and figures can be input according to the guide display of their stroke order.

[0006]

[Embodiment] An embodiment will be described below with reference to FIGS. 2 to 7. FIG. 2 is a block diagram of the writing learning device. The CPU 11 controls the overall operation of this writing learning device according to various programs stored in advance, and controls the characters read from the character shape/stroke order dictionary memory 12,
Graphics are displayed and output from a display device 15 constituting an input display device 14 via a display control circuit 13 .

The character shape/stroke order dictionary memory 12 stores various characters (
In addition to model patterns that represent the overall image of each character (hiragana, kanji, numbers, symbols, foreign characters, etc.) and figures, stroke patterns for each stroke are stored in accordance with the order of strokes. FIG. 3 shows the memory contents of the character "ma" stored in the character shape/stroke order dictionary memory 12, including a model pattern mP representing the overall image of the character "ma" and a stroke pattern for each stroke according to the stroke order. SP1, SP2, SP3
are stored sequentially. The CPU 11 is the character to be learned,
When a figure is designated, the model pattern of the corresponding character or figure is read from the character shape/stroke order dictionary memory 12 and given to the display control circuit 13, and then each stroke pattern is sequentially read out according to the stroke order. give to

The display control circuit 13 causes the display device 15 to display the entire image of characters and figures in dotted lines according to the model pattern read out from the character shape/stroke order dictionary memory 12, and also displays the entire image of characters and figures as dotted lines in accordance with the model pattern read out from the character shape/stroke order dictionary memory 12. According to each stroke pattern, the dotted line of the stroke portion is displayed blinking. In this case, the dotted lines are displayed blinking sequentially from the beginning to the end of the stroke portion.

The input display device 14 has a handwriting input device 16 stacked on top of the display device 15.
is a dot matrix type liquid crystal display device, and the handwriting input device 16 is a transparent touch panel device. When you touch the handwriting input device 16 with a pen or finger and trace the characters or figures displayed on the display device 15, The trajectory data is taken into the coordinate determination circuit 18 via the input control circuit 17.

The coordinate determination circuit 18 determines whether or not the input start/end point positions and the locus between them have been correctly traced. If the result is incorrect, the buzzer 19 is driven under the control of the CPU 11; If traced, the CPU 11 specifies the next stroke part, reads the stroke pattern from the character shape/stroke order dictionary memory 12, and displays it blinking on the display device 15 via the display control circuit 13.

The guidance display control circuit 20 displays a dotted line blinking in sequence from the start point to the end point of input in one stroke, and this blinking serves as a sign of the flow of prompting input. Note that the memory circuit 21 is a work memory.

Next, the operation of this embodiment will be explained. FIG. 4 is a flowchart showing the overall operation. First, specify the letters and figures to be practiced (for example, if there is a letter you want to practice by looking at the textbook, enter the number assigned to that letter from the handwriting input device 16. Also, if you specify the grade, you can specify the letter or figure you want to practice). (The kanji, etc. to be learned may be displayed randomly and automatically for learning.) Then (step A1), the CPU 11 searches the character shape/stroke order dictionary memory 12 (step A2), and searches the character shape/stroke order dictionary memory 12 (step A2). The corresponding characters and figures are read out from 12 and given to the display control circuit 13, and the entire image of the characters and figures is displayed with dotted lines from the input display device 14 (step A3). Here, FIG. 5(A) shows a sample pattern m of the character "ma" from the character shape/stroke order dictionary memory 12.
This is a display example when P is read out and displayed as a dotted line.

Next, the dictionary pointer (not shown) is reset (step A4). The in-dictionary pointer is used to sequentially designate each stroke pattern of characters and figures stored in the glyph/stroke order dictionary memory 12 according to the stroke order, and the pointer value is initially set to an initial value. After that, the process proceeds to step A5, where it is checked whether the value of the dictionary pointer exceeds the final pointer value that specifies the final stroke pattern of one character or figure, but the pointer value is currently set to the initial value. Therefore, the process proceeds to step A6, where guidance display and input processing for one stroke are performed. In other words, the parts and shapes of one stroke to be input are displayed blinking from the input start point to the end point for each stroke, starting from the first stroke part so that the stroke order (input order) of characters and figures can be seen. , displays the direction as a guide and prompts you to input one stroke.

FIG. 6 is a flowchart showing guidance display and input processing for one stroke. Now, the characters ``
When "ma" is specified as a character to be practiced,
If the initial value "1" is set to the pointer in the dictionary,
The first stroke pattern SP1 is read from the glyph/stroke order dictionary memory 12. This stroke pattern SP1 is an upper horizontal line forming the character "ma".

First, in step B1, a variable STP is set to the starting position of the stroke pattern SP1 found from the character shape/stroke order dictionary memory 12. In this case, Figure 5 (B
), the starting position of the stroke pattern SP1 is the part (1), so this value is set in the variable STP.

Next, the value of the blinking start pointer (not shown) is adjusted to the position of the variable STP (step B2).
). In this case, the pointer value will be "1". After that, this pointer position is highlighted (turned off) (step B3
), after this inverted display is displayed for the timer value (for example, 0.25 seconds) (step B4), it returns to normal display (lit) (
Step B5). In other words, the pointer position is displayed blinking. Next, "1" is added to the pointer value to increment the pointer value (step B6). As a result, check whether the pointer value has exceeded the final position (step B
7) If the pointer value does not exceed the final position, step B
Return to 3. Now, as shown in FIG. 5(B), the final position of the upper horizontal line that makes up the character "ma" is (6), therefore,
If the pointer value is "6" or less, the process returns to step B3. In this case, since the pointer value is "2", this pointer position is displayed in reverse video.

Thereafter, by repeating the above-described operation, the first stroke of the character "ma" is displayed blinking in the order from its starting point (1) to its ending point (6). Here, when the pointer value exceeds the end point (6), the process returns to step B2 and the pointer value is again adjusted to the variable STP. As a result, the pointer value becomes "1", and the first stroke of the character "ma" is similarly displayed blinking in the order from the starting point (1) to the ending point (6). Since such a blinking display serves as a sign to encourage the flow of input, the practitioner can use this guide display to know the part, shape, and direction of one stroke to be input.

Now, when the practitioner traces the guide display while touching the handwriting input device 16 with the pen in accordance with the guide display, the traced input portion is displayed as a solid line (step B8). Figure 7 is a display state diagram in this case, and the traced part is shown in Figure 5 (B
), parts (1) and (2)) are shown as solid lines. Next, the process proceeds to step B9, where it is determined whether the input for one trace has been completed or not based on whether or not the pen has been removed from the handwriting input device 16. Since one stroke is currently being input, the process proceeds to step B10, and the next position of the already traced portion is set in the variable STP. in this case,
Since the next position of the already traced part is part (3), "3" is set in the variable STP. Then, in order to return to step B3, the blinking guide display starts from the part (3) and prompts for input in the flow up to (6). In this way, the untraced portion is displayed as a dotted line, and the traced portion is displayed as a solid line, and as the pen moves (as the traced portion increases), the starting point of the untraced portion approaches the end point as needed. As a result, as the pen moves, the starting point of the guide display that blinks smoothly approaches the end point, and its length becomes shorter.

When the input for one stroke is completed in this way, the process exits from this flow and proceeds to step A7 in FIG. 4, where the locus from the input start position to the end position is stored in the storage circuit 21 as a coordinate string. Next, the coordinate determination circuit 18 determines whether or not tracing has been performed correctly based on the input position, shape, and input direction of the trace result (step A8).
. If the result is incorrect, the buzzer 19 is driven to generate a warning sound and a warning is displayed on the display device 15 (step A9). Furthermore, data for one stroke inputted is erased from the memory circuit 21 (step A1).
0), then return to step A6 and prompt for re-input. On the other hand, if the trace has been correctly performed, the process advances to step A11, where "1" is added to the value of the pointer in the dictionary and the pointer value is incremented, and then the process returns to step A5.

Thereafter, the above-mentioned operation is repeated for each stroke. Here, Fig. 5 (C) shows the guide display state for the second stroke, and Fig. 5 (D) shows the guide display state for the final stroke. ``You can practice writing different letters and shapes.

[0021] In the above embodiment, the entire image of a character or figure is displayed as a dotted line, and the display is made to blink for each stroke according to the stroke order. The information may be displayed step by step.

[0022]

[Effects of the Invention] According to the present invention, characters and figures can be entered according to the guide display of the stroke order, so anyone can accurately learn how to write characters and figures independently, regardless of the age of the learner. It becomes possible to learn. In particular, it is ideal for early childhood education because it allows you to learn stroke order accurately.
