Description

[Name of invention]

Compact Hangul Keyboard

[Technical field to which the invention belongs and the prior art in that field]

The present invention aims to propose a compact Hangul keyboard that can smoothly input Hangul alphabet using a phone dialing keyboard.

The dialing button on the phone, one of the compact keyboards, has ten numeric keys '1, 2, 3, 4, 5, 6, 7, 8, 9, 0' and two control keys '*' (asterisk), It is based on a twelve key matrix that combines '#' (shop). Dial a phone number with ten numeric keys and specify and call a specific service with two control keys. In order to input English letters on the dialing keyboard, as shown in Table 1, English letters are arranged in nine numbers from 1 to 9. This allows you to enter twenty six English characters with a small number of dialing keyboards.

If you want to enter alphabetic characters in the dialing key matrix of Table 1, switch to English alphabetic input mode by pressing the promised control key, and then press numeric keys repeatedly as shown in Table 2.

A typical character input device is composed of a keyboard arranged with a plurality of keys assigned with scan codes, a micom scanning a keyboard, at least one key code data, and a key code buffer for storing key codes. As a result, ASCII codes are read by reading scan codes, and scan codes and ASCII codes are provided through key buffers.

In a dialing keyboard that inputs English characters, the character input device reads the SCAN code value of the key matrix and calculates the ASCII code value when a key is pressed.

The character input device of the dialing keyboard should refer to the key combinations of Table 2 in the character input mode in order to recognize the alphabetic characters arranged in the numeric keys of Table 1.

Table 2 Key combination '2' to input 'A', '2', '2' key to enter 'B', '2', '2' and '2 to enter' C ' To input 'key' and 'ABC', press '2' key, no input for a certain time, '2', '2' key, no input for a certain time, '2', '2', '2' key. . A certain time of no input is recognized as a signal that distinguishes the unit of key combinations from the character input device, and scan codes '01', '01, 01 'and '01, 01,01' are ASCII codes 97, 98, 99 is computed and provided to the key buffer sequentially.

This key input method is low efficiency and delays the input time for each character combination, and the character input speed becomes very slow.

On the other hand, it is possible to input various characters such as Korean, English characters, Japanese (applied in Japan in the early 90's) to the character input device by giving a two-digit decimal code to the character's letter and inputting the character code as a numeric key. However, such a character input method has a problem of low practicality and efficiency, such as the user can perform input code conversion, so that character information can not be input without a code table and the accuracy of information input is reduced in a real-time input state.

The input of Korean characters using a conventional telephone dialing keyboard is dependent on the English alphabet input method.

Table 3 shows an example of inputting an English alphabet using the dialing keyboard of Table 1 of the telephone. It can be seen that the English alphabet of Korean has a long character string and the dialing keyboard inputs one alphabetic character with one, two or three keystrokes.

[Technical problem to be achieved]

An object of the present invention is to propose a compact Hangul keyboard which enables quick and easy input of Hangul with a small number of keys including a dialing keyboard.

The present invention is to propose a compact Hangul keyboard that can input Hangul in the order of reference by referring to the Hangul alphabet assigned to a key without referring to a code table.

An object of the present invention is to propose a compact Korean keyboard which allows the input of Korean characters continuously according to the ligature characteristics of Korean characters, with a very low frequency of use of distinguishing symbols (such as no time input) of key code combinations.

[Configuration and Function of Invention]

In this invention, the vowel stroke, person, sky, and earth 'ㅣ', '·', 'ㅡ' Samjae is assigned to Seki and the short vowels ㅏ. ㅓ. ㅗ .TT. ㅡ. ㅡ. 모음. ㅔ. ㅚ. ㅟ열 and ㅏ. ㅕ. ㅛ. ㅠ. ㅘ. ㅒ. ㅖ. ㅙ. ㅞ. ㅢ. ㅟ Twelve vowels, etc. Let the vowels be ligated. Assign four consonants, two consonants per key, to seven keys, and press the consonant key once or twice to release fourteen consonants and four consonants. . ㅉ. ㅆ Allows you to type five vowels, vowels are typed by stroke in keystroke order.

Consonants select the assigned consonants by pressing the consonant keys once or twice.

Specifically, the first consonant a, c, ㅁ, ㅅ, ㅈ, ㅋ, 중 of the two consonants assigned to one key is selected by pressing the key once.

One key The second consonant of the two consonants assigned to it is selected by pressing the key twice: b, ㄹ, ㅂ, ㅇ, ㅈ, ㅊ ,,, ㅎ.

To enter the second consonant of the consonants b, ㄹ, ㅂ, ㅇ, ㅊ, ㅌ, ㅎ, you can include a shift key as a control key, as in a typical Korean keyboard, and use '(Space)' as a specific character, and In order to input '-', a key combination as shown in Table 4 below, which is distinguished from other control key combinations, may be included.

As described above, the present invention is characterized in that the vowels and consonants of the vowels and consonants are combined in the writing order of the vowels of the thousand, ji, and humans in the writing order of Hangul to provide the Hangul code. ; By including the editing keys of the characters in the control keys, the precision and convenience of Hangul input by the compact Hangul keyboard can be improved.

Example 1

The compact Korean keyboard applied to the telephone dialing keyboard is as follows.

Example 1 The order of key input, number of key inputs, and number of alphabets of Korean input using a compact Korean keyboard are shown in the table below. Compared to the number of key inputs 81 and number 31 of alphabets according to the input of Korean characters of 9 in Table 3, the compact Korean keyboard of Example 1 has 42 key inputs and 25 characters, which greatly improves the efficiency of Korean input. Able to know.

However, in Example 1, when the first consonant a, c, ㅁ, ㅅ, ㅈ, ㅋ, 자 of the two consonants assigned to one key is supported and becomes the first consonant of the next letter, a separator must be entered between the letters. For example, the key input of 'Gamma' is '4126612', which is the same as the key input '4126612' of 'Gabba', so you need to input '4126', character separator, and '612' to distinguish the two characters. In this embodiment, the character delimiter is no input for a predetermined time.

In addition, the present invention can facilitate the input of the characters in the phone number because the Hangul input is facilitated in the dialing keyboard of the phone as above.

The character representation telephone number service station, which is represented by the station number 800, receives a character code and calculates a connection telephone number with reference to the data, and calculates or inputs a key combination arranged as a combination of character keys in the numeric input mode. This can be done by assigning a combination of keys to the connecting phone number. First of all, an idea that can be put into practical use is to connect the first consonant of a Korean phone number to a phone number as in the example below.
