Abstract

PURPOSE:To provide a device for learning the stroke order of characters, allowing the stroke order of any characters to be easily learned through repetition. CONSTITUTION:When a character designated by a keyboard portion 3 is kana, a CPU 12 reads the pattern data and stroke-order data of kana characters from a CG ROM 16; when the character is kanji, the CPU 12 reads from the CG ROM 16 the pattern data and stroke-order data of the kanji recognized by use of the kanji dictionary of a kanji ROM 15, and then causes an LCD 6 to blink to display the pattern of that portion which corresponds to the first stroke of the character. When information entered from a digitizer 8 about handwriting done with a pen 10 is correct, the mode of display is switched from blinking to full-light, and the pattern of that portion which corresponds to the next stroke is displayed by blinking light in accordance with the stroke- order data. After the pattern of the final stroke has been displayed, the correctness of the stroke order is indicated. If no correct handwritten entry is done even a predetermined time after the patterns have been displayed by blinking light, the incorrectness of the stroke order is indicated and processing is complete.

A schematic side sectional view of the operation display screen 2 is shown in FIG. 3 (a), and a schematic plan view thereof is shown in FIG. 3 (b). As shown in FIG. 3A, the operation display screen 2 is formed by sequentially laminating an insulating film 7, a digitizer 8, and a surface protective film 9 which are transparent on the lowermost LCD 6.

The LCD 6 shown in FIG. 1 (a) includes a reflection member (or backlight member) 6-1, a Y electrode (horizontal scanning electrode) 6-2 made of a transparent conductive film, and an alignment film 6 made of a polarizing member.
-3, a liquid crystal 6-4, another alignment film 6-5, and an X electrode (vertical signal electrode) 6-6 constitute a known matrix type display screen. In the liquid crystal 6-4 of the LCD 6, a portion (dot) 6-4a sandwiched between the intersections of the Y electrode 6-2 and the X electrode 6-6 is applied from both electrodes as shown in FIG. It is turned on (see dot 6-4a ') or blinks (see dot 6-4a ") by the drive voltage.

On the other hand, the upper digitizer 8 is shown in FIG.
As shown in (a), a Y electrode 8-1 made of a transparent conductive film,
A grid-shaped transparent insulating member 8-2 and an X electrode 8-4 made of another transparent conductive film disposed with an insulating gap 8-3 interposed therebetween, and a Y electrode 8-1 and an X electrode 8-4. Intersect each other at a right angle, and their intersections 8-5 form a matrix-type input operation surface as shown in FIG. These intersections 8-5 correspond to the dots 6-of the LCD 6, respectively.
There is a one-to-one correspondence with 4a. In the digitizer 8, when the pen 10 is handwritten on the surface protection film 9, the X electrode 8-4 pressed by the tip of the pen 10 at the intersection 8-5 bends and comes into contact with the Y electrode 8-1.

Next, a block diagram showing a hardware configuration of a control unit provided inside the character learning device 1 is shown in FIG.
Shown in. As shown in the figure, the bus line 11 of the control unit includes the above-mentioned keyboard unit 3, digitizer 8, and LCD.
6 are connected via a keyboard driver 3a, a scan driver 8a, and an LCD driver 6a, respectively. Further, the bus line 11 includes a CPU (central processing unit) 12, a ROM (read only memory) 13,
RAM (random access memory) 14, dictionary RO
The M15, the CG / ROM 16, and the display memory 17 are connected. Hereinafter, these configurations will be described.

The keyboard driver 3a scans all the key operation states of the keyboard unit 3 in a constant cycle and outputs operation information input by the key to the CPU 12. The scan driver 8a is the X electrode 8 of the digitizer 8 shown in FIG. 3 (a).
-4 and the Y electrode 8-1 are driven by a well-known matrix scan switch method to recognize an intersection point between the X electrode 8-4 and the Y electrode 8-1 which are pushed and brought into contact with each other by the tip of the pen 10. Then, the coordinate data is output to the CPU 12.

The LCD driver 6a is controlled by the CPU 12 so that the X electrode 6-6 of the LCD 6 shown in FIG.
Further, by applying a drive voltage to the Y electrodes 6-2, information to be notified to the user in response to the operation of the keyboard portion 3 is displayed on the LCD 6 in the initial setting, and is recognized by the digitizer 8 in learning the writing order of characters. Depending on the operation position of the pen 10, the writing order of characters to be notified to the user may be changed to L
Display on CD6.

The ROM 13 stores a program for processing for learning the writing order of characters, and the CPU 12 executes the R program.
The program read from the OM 13 controls the display process for sequentially displaying the writing order of characters based on the coordinate data of the operation position of the pen 10 input from the scan driver 8a.

The RAM 14 has an application program area and temporarily stores a program for writing order learning processing of foreign characters read from a memory card mounted in the card slot 4 until the processing by this program ends. Remember. Further, the RAM 14 has a storage area used as a work area and stores key operation information input from the keyboard unit 3, handwriting operation information (coordinate data) by the pen 10 input from the digitizer 8, and the like.

The kanji ROM 15 is a kanji dictionary memory, and the CPU 12 searches the kanji dictionary of the kanji ROM 15 to search the kanji if the kana / kanji conversion is specified for the character data keyed in from the keyboard section 3. Recognize.

The CG / ROM 16 is a ROM for storing character pattern data corresponding to a character, for example, which is composed of an outline font, and writing order data which is a combination of center coordinates of the outline font and a writing order.
Multiple different types of font data are stored.

The display memory 17 is a frame memory having a capacity for storing pattern data for one operation display screen 2. The CPU 12 analyzes the handwriting operation information (coordinate data) input from the digitizer 8, generates pattern data corresponding to the writing order by the CG / ROM 16 based on the obtained result, and stores the pattern data in the display memory 17. Write on the specified address and expand it,
The developed pattern data is transferred to the LCD driver 6a at the timing to be displayed.

Next, FIG. 4 is a flow chart showing the processing operation of the character writing order learning according to the embodiment having the above-mentioned configuration. The operation will be described below. In this process, the character learning device 1 is powered on and the keyboard unit 3
When the learning mode for displaying the stroke order of characters is designated by key input from, the CP of the control unit shown in FIG.
Execution is started by U12. Further, in this process, although not shown in particular, in the work area of the RAM 14,
One counting area (timer A) and two constant areas (register B and register C) are provided. When the power is turned on, initialization is performed and timer A is cleared to "0".
Predetermined time data T ₁ is set in the register B, and other time data T ₂ (T ₂ > T ₁ ) is set in the register C.

First, a display is displayed on the operation display screen 2 instructing the user to specify the character for learning the stroke order (step S1). Next, a key input from the keyboard unit 3 is awaited, and it is determined whether the character designated by this key input is a kana or kanji character (step S2).

If the designated character is a kanji, the kanji dictionary memory of the kanji ROM 15 is searched to recognize the designated kanji (step S3), and the pattern data and stroke order data of this kanji are stored in the CG / ROM 16 Are read out from (step S4). On the other hand, if the designated character is kana, the process immediately proceeds to step S4, and the pattern data and writing order data of this kana character are stored in the CG / ROM 1
Read from 6.

Then, based on the pattern data and the writing order data read from the CG / ROM 16, the character pattern of the portion corresponding to the start point (first writing order) is written on a predetermined address of the display memory 17. Then, the developed pattern data is transferred to the LCD driver 6a together with the blinking instruction signal. As a result, the first writing point (dot 6-4a) of the designated character is displayed blinking on the operation display screen 2 (see dot 6-4a ″ in FIG. 3B) (step S5).

Next, the timer A is set (step S
6) It is determined whether or not the corresponding point (point blinking) is pointing (handwriting operation with the pen 10) (step S7). Then, if the corresponding point is pointed (S7, Y), the timer A is reset (step S8), and the previous point (the corresponding point that has been blinking until then) is lit up (dots in FIG. 3 (b)). 6-4a ') (step S9).

Subsequently, it is determined whether or not the display of all the character pattern points of the designated character is completed by referring to whether or not the pattern data corresponding to the final writing order of the designated character has been expanded in the display memory 17. (Step S10).

If the character pattern in the final writing order is not displayed yet (S10, N), the address (coordinate data) of the next point (dot 6-4a to be the next corresponding point) is CG. Read out from the ROM 16 (step S11), and the dots 6-4a (next point) of these addresses are displayed as blinking as a new corresponding point (step S1).
2) and returns to step S7.

Thus, when the point which is blinking displayed on the operation display screen 2 is traced with the pen 10, the point is switched to the lighting display, and the point to be written next to the character pattern is newly blinked and displayed (Fig. Refer to the blinking pattern 5 in the middle of the designated character "A" of 2.) Then, the switching to the lighting display and the new blinking display are sequentially repeated according to the writing order.

In this way, when the steps S7 to S12 are repeated to blink the character patterns in the final writing order and it is confirmed in step S10 that the display of all the points of the character pattern is completed. Is the operation display screen 2
Then, for example, a correct answer such as "Good job!" Is displayed (step S13), and the process is terminated.

In step S7, if the pointing has not been performed yet (S7, N), the timer A is incremented by "1" (step S14), and the incremented timer value and the time set in the register B are set. The data T ₁ are compared (step S15).

In this comparison judgment, if the timer value is smaller than the time data T ₁ , it is judged that not much time has elapsed since the corresponding point was displayed, and in this case, the process returns to the step S7 and again. Determine whether the corresponding point was pointed.

On the other hand, in step S15, if the timer value is the time data T ₁ or more, the corresponding points are displayed,
It is determined that the time has passed moderately, and in this case, an accelerating alarm prompting promptly to point is sounded (step S16), and then the timer value and the time data T ₂ set in the register C are displayed. The comparison is made (step S17).

If the timer value is smaller than the time data T _2, it is determined that correct input may be performed, that is, there is still room to wait for input, and the process returns to step S7. On the other hand, if the timer value is equal to or more than the time data T ₂ , it is judged that it is useless to wait for further input, and an incorrect answer display such as “Try again!” Is displayed on the operation display screen 2. Ends the process.

In this embodiment, the hiragana "A" is used.
However, the characters for which the stroke order is learned are not limited to hiragana, and may be katakana, kanji, romaji, or any foreign character such as Hangul or Arabic. There are various possible applications.

Further, the outline font data is used for the data of the CG / ROM 16, but any format may be used as long as the data stores the display address corresponding to each character pattern and the display order according to the writing order. .

Further, the pen operation position by the digitizer is detected by the contact between the X electrode and the Y electrode due to the pressing of the pen tip. However, the method is not limited to this method and electromagnetic induction, electrostatic coupling, electric resistance film, static electricity A method using a resistance film or the like may be used.

[0037]

As described above in detail, according to the present invention, since the learning input is performed by using the operation display device including the liquid crystal display device and the digitizer, the learning input can be repeatedly used, and thus it is economical. Also, since the character pattern position to be written next is displayed in blinking in order according to the writing order,
The stroke order is clear, and therefore the pen operation can be easily performed in the stroke order. In addition, because the characters are specified by key input from the keyboard, it is easy to select the characters and there is no time and effort to manage and search for the character patterns, and therefore the stroke order learning with the desired characters is easy at any time. It can be carried out. Also, since the character pattern can be changed by replacing the memory card, it is possible to display any character in each country in the world and learn the writing order.
