Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and device for inputting Chinese characters using a diagonal double phonetic method, which is suitable for inputting Chinese characters into a Chinese character input device, and particularly for quickly inputting Chinese characters with a few operations. In addition, here, the kanji are
It includes ideograms like pure Kanji as well as Hangul characters.

The problem with kanji input is the large number of character types, and the need to consider thousands of input types, which is incomparable to other languages. Many methods have been proposed and studied up to now, but they can be broadly classified as follows.

(1) A full keyboard method that uses the number of keys corresponding to the number of kanji characters to input kanji directly, and (2) a kana-kanji conversion method that inputs the kanji reading from kana amemori and converts it to kanji within the device.

(3) An associative memory method in which an associative code consisting of two Kana characters is assigned to each Kanji character, input from a Kana keyboard, and the Kanji characters are output within the device.

(4) A character shape synthesis method in which a kanji character inputs nine character shapes with different kanji characters and synthesizes them to obtain the desired kanji character.

There is also a numeric code method in which several digits are assigned to kanji characters and input using numeric keys.

The full keyboard method (1) is well known and most reliable for Japanese text type, Kanji teletype, etc., but in order to increase the number of characters used, the keyboard needs to be large, and character selection,
Keystroke operations are complicated and input speed is slow. Furthermore, there is a drawback that there is no home position on the keyboard, resulting in operational fatigue.

(2) The Kana-Kanji conversion method is easy to operate, but the handling of homophones poses a problem. For example, if you enter "Kouka", "Effect Ha", "School Song Ha", "ll$ 下", "Shanghai Ha", etc.
The desired kanji must be selected from among 12 characters such as "hardening" and "coin." In this case, a method is often adopted in which a grammatical judgment is made from the surrounding context, or a method is used in which all the characters are displayed on a display and the desired kanji is selected. In the former case, the grammar judgment algorithm is complicated, and in the latter case, a selection operation must be performed every time a homophone occurs, which is cumbersome.

Method (3) is the fastest input method for the operator once he or she becomes proficient, but it is difficult for the operator to enter all the kanji in almost any way, such as ``Kagami-[Miraha-mo-'', ``Mama-ha-kari--''Meri'', etc.''. Significance 2
You must memorize the character association codes. Therefore, an extremely high level of skill is required, and since the operator first obtains a string of kanji characters by a set of corresponding associative symbols when inputting a sentence, it is easy for the operator to become mentally fatigued if the operation continues for a long time. There is.

(The 420 glyph composition method is easy for beginners to solve, but it requires inputting several glyph shapes and shapes, so the keyboard has too many keys, making the operation complicated. The speed is slow.Also, there are some cases where you have to input the shape of the characters in the order of the strokes, and in that case, there was a drawback that you could not input it unless you knew the stroke order.

7C. The numerical code method is used when there are a small number of kanji, but the number of codes increases according to the number of kanji used, and the number of codes required for the operator to memorize becomes enormous. is generally difficult.

As described above, some of the various methods that have been tried and partially put into practical use require large devices that are inconvenient to operate, and others require long-term training or cause mental fatigue. However, there have been many drawbacks such as the tendency to occur, and it has been very difficult to operate quickly, reliably, and over a long period of time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method and device for inputting Chinese characters using a novel diagonal double sound system.

This object is achieved by a Kanji input device according to the claims.

According to the kanji input device according to the present invention, the normal JIS
It is sufficient to use a 2-key layout, a 50-syllabary keyboard layout, etc., and allocate a character shape to a part of a normal keyboard as shown in FIG. In addition to kanji (for example, by making a sticker as shown in Figure 1 and pasting it on the key surface), it is possible to input kanji quickly and reliably, including hiragana, katakana, alphanumeric symbols, etc. The operator also determines whether to press two keys based on the form of the kanji and inputs the first sound of the reading as the third information, so the processing method is simple and can be fully operated with a short training period. It will be done. Furthermore, it has the following characteristics when compared with conventional methods.

The number of keys is simpler compared to the full keyboard method. As a result, the normal keys &-1'' can be used for high-speed input.

Compared to the associative memory method, although it requires more keystrokes, it eliminates the enormous effort and long-term training required to memorize the associative symbols of all kanji.

Compared to the kana-kanji conversion method, #i conversion operations are not required, and the number of homophone selection operations is greatly reduced, allowing high-speed input.

In the glyph composition method, three or more glyphs must be entered to input one kanji, and the number of glyphs required is significantly larger.Since the number of glyphs on a normal keyboard is insufficient, a special key I is required. − code is required.

Also, there are too many keys, so touch typing (a method of typing without looking at the keymate like English typing).

It is impossible to do so (improve the speed significantly). In comparison, the method of the present invention allows touch typing because a normal keyboard can be used, and therefore the input speed is greatly increased.

As mentioned above, the method in this case, the diagonal double phonetic method, does not require special equipment, is easy to memorize, and can input kanji at a practical speed. It is a method that can be used equally and commonly by all types of input experts.

The present invention will now be described in detail with reference to the accompanying drawings showing examples.

FIG. 2 is a schematic configuration diagram of an input device according to the present invention.

In the figure, a computer 1o can be a microcomputer with a kanji ROM. This computer lO
Display 11. A printer 12, a keyboard device 13, a floppy disk device 14, and two pedals 15 and 16 are connected. As the display 11, the printer 12, the floppy disk device 14, etc., it is possible to employ devices that exhibit a peripheral function. The Keysade installation [13 is as described above.

FIG. 1 shows an example of a keyboard that can be used for the character input system of the BiJK. In this keyboard, the first information that determines the form of the kanji is extracted by focusing on the upper left corner as the first corner of the kanji, and the second information is focused on the lower right corner as the second corner of the kanji. Character subelements are extracted. The partial element indicating the feature of which part of the kanji is indicated by the position on the key, which indicates that it is located at the upper left or lower right. Note that the kanji elements displayed in the center of the key have the same first and second information, but are displayed together in order to avoid the complication of displaying two of the same kanji elements. It's just that. In addition, the kanji elements are arranged in order to improve fingering efficiency and take into account the frequency of appearance of the kanji elements. It goes without saying that the extraction of the features of each part of a kanji character is not limited to this example, and that other forms can also be adopted, and the arrangement can also be the same.

Furthermore, it is convenient for the conventional keyboard to use function switches operated by fingers or pedals, and to have a mechanism for switching between kanji, alphanumeric symbols (numbers, alphabets, symbols), hiragana, katakana, etc. on the top of the keys. . This is to change the character type mode by operating a key with either the left or right finger or using a pedal switch, and by combining the keys as appropriate.

When operating the keypad, first select the kanji mode using the function switch, and then use the wc1 kanji information (for example, the kanji element focused on the upper left corner of the kanji), which is determined based on the form of the kanji, and the second kanji information (for example, the kanji element focused on the upper left corner of the kanji). - Key-operate the kanji element focused on the lower corner of the cloth, and then input the first sound of the reading of the kanji using the one-kana key or the alphabet key.

By performing these three key operations, the corresponding kanji character is identified and a corresponding electrical signal is generated. During such operations, the kanji elements and kana characters corresponding to the keys input, the kanji characters, etc. are displayed each time on the display surface so that the operator can visually check them.

In addition, if the first and second information of a kanji determined by the form of the kanji have been determined, but the reading is unknown, enter the symbol "?" as the third input. It is possible to display all kanji characters having characteristics and different pronunciations on a display, and to select a desired kanji character from among them.

The pedal switches 15 and 16 are the pedal switch 15
It is possible to switch between hiragana, katakana, alphanumeric characters, etc., and use the pedal switch 16 to switch from any of the above-mentioned character types to kanji elements. It is also possible to use a combination of both as appropriate. Note that, as described above, the same functions as the pedal switches 15 and 16 can be obtained by using finger-operated function keys and the like, and the two can be used in combination. It will be clear that this pedal switch is capable of many variations or modifications, such as the use of three pedal switches.

In this example shown in Figure 2, JIS 1st standard 29
A processing device or computer is used which has a ROM'ft containing 65 characters of Kanji, Hiragana, Katakana and alphanumeric symbols. In such a configuration, for example, Kyoto's "
When manually inputting ``Kyo'', as mentioned above, the kanji partial element ``ni'' is extracted by focusing on the features in the upper left corner, and the kanji partial element ``to'' is extracted by focusing on the characteristics in the lower right corner. , and then input the kana ``ki'', which is the Ml sound of the pronunciation ``kyo''. When these three types of input information are input to the processing device, the processing device operates, and the read-only memory RO
Pull out the corresponding kanji "Kyo" in M. In this example, we focused on the kanji form in the upper left corner and extracted 40 types of kanji partial elements.
There are 38 types of Kanji partial elements extracted by focusing on the lower right corner.

These allow input of the above-mentioned character types.

It should be noted that hiragana, katakana, alphanumeric symbols, etc. other than kanji can be input in one action while the mode is switched to the respective character type mode.

Processing bag #10 has a character or document editing function, edits the text as appropriate while displaying it on display 11, and prints out the final output using printer 12 or outputs it to another device such as floppy disk device 14. can do. Therefore, it can be applied to Japanese data terminals, Japanese data entry systems, word processors, etc.

In this case, it is also possible to add various functions such as a non-standard character registration function, a word short sentence registration function, a verify function, and a communication function depending on the purpose.

Although preferred embodiments of the invention have been disclosed, it will be obvious that many variations and modifications may be made within the scope of the invention, including adaptations to the Chinese language.
