Abstract

Dialing Keyboard allows you to input Hangul by using ten keys of the keyboard. One key is assigned to each key of a vowel, and unique codes are assigned to each key. A key is inputted in the order of writing to produce short vowels and double vowels. The control unit recognizes the consonant as a consonant combination delimiter when another consonant family key or a collection key is input, and a collection key that is out of the collection key combination type or a consonant key is input The character code is recognized as a vowel combination delimiter, and the character code in which the combination is completed is stored in the key buffer so that the main code is referenced by the main processor.

According to the present invention, as a compact keyboard, it is possible to quickly input Hangul with a key input less than the stroke number at the time of writing.

Description

Hangul code input device of compact keyboard

This invention proposes a Hangul code input device of a compact Hangul keyboard.

A keyboard is a device for inputting characters into a computer. The keyboard and main processor are connected to the ground pin, power pin, control pin and data pin of the cable connector. The scan code (ASCII code) and alphabetic ASCII code inputted through the character key are stored in the key buffer, and the main processor reads the scan code string and the character code string stored in the key buffer.

The input and processing of Korean characters through the keyboard differs from the inputting process of alphabet characters.

Press the key to switch the keyboard control to Hangul operation mode. The code input to the two-beater type standard Korean keyboard is different from the ASCII code as shown in FIG. In the first step, the B ₇ bit is set to 1 in the Korean keyboard code, and the main processing unit makes the Korean word mark. The B ₇ code identifies a 7-bit ASCII code containing Korean and English characters. This bit cover is also confused with an extended graphic (line) code with B _{7 set} to 1 in the alphabet processing system.

The 8-bit code input key code provided to the main processing unit through the key buffer is calculated as a 2-byte Hangul code according to the Hangul syllable writing rule in the Hangul processing system of the input / output device (BIOS). The process of collecting Korean Hangul is to convert Korean consonants, vowels, and consonants entered in handwriting order into Hangul syllable units and convert them into Hangul codes. Depending on the need, a combination of input key codes may be used to calculate backing up phonemes (eg, ㅄ, ㅀ, ㄵ, ㄶ,., ㄻ, ㄼ, ㄽ). In FIG. 1, _the 2-bit code _of B ₆ B _5, which identifies the terminal sound, the twin consonant, the horizontal vowel, and the vertical vowel, reflects the syllable writing characteristics of Hangeul.

The Hangul code input device of the Hangul keyboard is used for Hangul input devices such as a computer, an electronic note, a communication device, and a control device.

The input key collected on the Korean keyboard in Figure 1 is a combination of nineteen characters ㄲ ㅉ ㅉ ㅉ ㅃ ㅆ ㅆ ㅉ ㅉ ㅉ ㅃ ㅆ ㅆ ㅆ ㅆ ㅉ ㅉ 과 과, This is a thirty-three year old.

It has fourteen terminal tones 및 및 및 및 및 다 다 다 5 ㄲ ㄲ ㅃ ㅆ ㅆ ㅆ ㅉ ㅆ ㅆ ㅆ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ ㅒ It is less than the number of characters in Hangul which is composed of ㅖ ㅙ ㅞ ㅢ ㅢ, but insufficient code is able to calculate the code value in the Hangul writing process as mentioned above.

In addition, a 3-ball type keyboard is also used for assigning a diphthong which is frequently used as a Hangul input keyboard to a Hangul key.

The dialing button of the phone, which is one of the compact keyboards, is a combination of ten numeric keys (ten keys) '1 2 3 4 5 6 7 8 9 0' and two control keys '*' (asterisk) and '#' The basic configuration is a twelve key matrix. Dial a telephone number with ten keys, and assign or invoke a specific service with two control keys. Dialing To input alphanumeric characters in the keyboard, two alphabetic characters or two alphabetic characters are repeatedly arranged in nine digit keys 1 to 9 as shown in Fig. If you want to input alphabetic characters by using the keyboard of the second figure, switch to alphabet input mode. Press the key once for the first alphabet letter, press twice for the second alphabet letter, press the key three times for the third alphabet letter, A non-input signal is input for a predetermined time. This allows you to enter up to twenty-six alphanumeric characters with fewer dialing keyboards. As you can see in Figure 3, typing an alphabetic character with a compact keyboard requires more typing and a non-typing time code to distinguish between alphabetic characters. In the case of inputting Hangul in English, the inefficiency becomes larger as quoted in FIG. 4. As in the case of an alphanumeric compact keyboard, it is conceivable that the thirty-three alphabets of the Korean keyboard are arranged in two or four increments on the ten-key to input Hangul. If you enter Hangul at this keyboard, efficiency will be lower than alphabet letter input, so you can not maintain practicality. The inventor of the present invention evaluates that when the Hangul input is performed on a compact keyboard, the number of times the key input is performed is greater than the number of times the Hangul is written.

An object of the present invention is to propose a Hangul code input device for a compact Hangul keyboard which improves difficulties such as inefficiency delay experienced when inputting Hangul with a compact keyboard as cited above.

The present invention relates to a method and apparatus for generating a four-bar vowel code of eight short vowels and six vowels of a standard keyboard by assigning a letter key, Provide,

Terminal sounds Provide the main processor with seven terminal keys, one terminal key seven times, the second terminal key seven times, the third terminal key three times, and the five phoneme five codes.

FIG. 5 is an embodiment of a compact Korean keyboard for inputting Hangul.

The 5th or the 5th digit is the dial button arranged on the keyboard of the triplet 1 2 3, 4 5 6, 7 8 9, (ㄱ ㄷ) (ㄷ)) (ㅋ)) (ㅎ ㅎ). The consonant family of consonants can be grouped by frequency of use, consonant consonants, or rearranged in any combination in addition to (ㄱ ㄷ) (ㅁ)) (ㅅ ㅇ) . In the present invention, the transition family of consonant refers to a consonant family which is repeatedly pressed the same key or calculated together with the control key.

5a and 5b, the dial buttons are arranged in reverse order.

In the 5th and 5th degrees, the numerical values of the dial buttons are reversed, the vowel character sequences are arranged in the right column seki, and the consonants arranged in two letters are arranged in the remaining seven keys.

5d is the same as FIG. 5c, but the numerical values of the dial buttons are arranged in a regular order.

Figure 5e shows that the vowel sequences are arranged in the first line and the pairs of consonants are randomly arranged considering the frequency of use. However, the consonants were not considered to be the consonants of the loser.

Figure 5f also adds a shift key to the compact keyboard of Figure 5a

FIG. 6 is a character code table of the first consonants and two vowels of the two consonants assigned to the seven keys of the compact keyboard of FIG. These abbreviated character codes are consistent with the standard Korean alphabet code of FIG. 1 in the embodiment. The code of the vowel character stroke '·' is the code assigned to the key uniquely in this invention.

Fig. 7 shows that the 5th a is also the second terminal sound by pressing the seven keys assigned to the terminal two times by the keyboard once, and the second terminal sound by pressing the terminal sound,, ㄷ, ㅁ, ㅅ,,, 일, , ㅌ, ㅎ, ㅎ seven, consonant keys, control keys (*), and consonant keys such as ellipses ㄲ, ㄸ, ㅃ, ㅆ, 이다

Since the compact keyboard of the present invention collects the consonants into a family of transition units of the key unit and applies the combination rule of consonants and vowels, the input key code continuously inputted can be distinguished by consonant or vowel unit. This effect is a factor that greatly improves practicality compared to an alphabet letter input device for inputting a non-input code (time delay) for a certain time between characters

As an exceptionally rare case, in the key combinations of the keyboard of FIG. 5a and the key combination of FIG. 7, the first consonants of the consonants of the family are a, c, k, g, i, If it becomes a consonant, you must enter a separator between the letters. For example, the key input of 'gamma' is '4126612' in FIG. 5a and is the same as '4126612' of 'Gaba', so a delimiter between 4126 and 612 must be entered to distinguish the two letters. In this case, to correctly calculate the code, the character separation control must use the non-input character delimiter for a certain time.

FIG. 8 shows another example of a key combination that solves this problem. As shown in FIG. 8, the consonant shifts seven consecutive terminal keys seven times by assigning two terminal sounds per group, ) And press the same consonant key to produce five codes for the loser.

9 is a code conversion table for calculating eight short vowel sounds and six double vowel sounds by a combination of consonant key sequences assigned to Seki. The control unit inputs the vowel code of the preceding vowel code as the completion of the vowel combination when it goes out of the vowel code table type or when the consonant key is inputted

The present invention includes key combinations of necessary symbols such as a space, a back space, a dash, and numerals (0 to 9) as shown in FIG.

FIG. 11 shows an example of inputting Hangul in a compact Hangul keyboard using FIGS. 5a, 7, and 9, and it is shown that Hangul can be input by a key input less than the number of Hangul characters in a compact Hangul keyboard.

FIG. 12 shows a keyboard control embodiment in which the character code obtained from the key input is provided to the key buffer after completion of code editing.

In the code editing of the consonant, the code edit mode is performed in the transition family of the consonant, and when the code of another transition family is inputted or the collection letter key is inputted, the code editing is finished and the character code is inputted into the key buffer.

In FIG. 7, the transition of the consonant is performed when the (a) key is pressed once, the (a) key * key and the (b) key are pressed twice in the code '10000001' When a key is pressed, code value is calculated by 'ㄲ' code '10100010'. In this process, if the keys of the other family are input, (,), (), (), (), Put the code value into the key buffer and start code editing again with the final input key value starting

The code editing of the vowel transits the code according to the key combination shown in the code table of FIG. 9, and when the key combination is not found in the code table or when the consonant key is inputted, the code editing is terminated and the current code is inserted into the key buffer

The key buffer can buffer several codes, which are referenced in order of input in the main processing unit, and one or several codes in the main processing unit are combined into a binary or double-byte code or a 2-byte Hangul code

In FIG. 8, the consonant transition operation is performed by pressing the (a) key once and pressing the 'a' code '10000100' when the shift key is pressed together with the shift key , The code value is calculated as 'ㄲ' code '10100010' when the (a) key * key and (a) key are pressed. In this process, if the keys of the other family are input, (,), (), (), (), Put the code value in the key buffer and start editing the code again, starting with the input key value

The key combination type of the consonant family and vowel in the haircut name is not limited to the example of FIG. 7 and FIG. 8, and the frequency of use of characters, adjacency between codes, collision characteristics such as concatenation of lexical sounds by pressing the same consonant key three times Other combinations can be considered.

Figure 5g is a keyboard with consonants similar in shape to each other. Step 5g also presses the consonant key to type the first consonant on the keyboard and the consonant key and the control key to type the second consonant. Use the '*' key or the '#' key as the control key. Control keys can be pressed at the same time as the consonant key or before the consonant key, or after the consonant key. This keyboard allows you to enter numbers in Hangul input mode.

The person who enters Hangul at the keyboard first finds the consonant of the keyboard. Therefore, it is natural to press the consonant key first and then the control key after considering such a visual path. In this case, the key input of the keyboard in the 5g is as follows.

Thus, the present invention allows a three-key sequence of a vowel to be assigned to three keys to calculate a vowel code as a key combination, and a compact key that allows all the keys of the Korean alphabet to be keyed by a small number of keys, The present invention provides a Korean keyboard input device, and moreover, it is possible to input Hangul by a fewer number of key input than the number of strokes of Hangul, to automatically identify the distinction between characters, And it can be applied to the dialing key of the telephone. Therefore, it can greatly contribute to the mechanization of Korean language and the development of information, such as the display of the Hangul character of the telephone number.
