Description

Hangul input device and method

The present invention relates to a Hangul input device and method using a plurality of keys, and more particularly to an apparatus and method for enabling the input of the Hangul with a minimum number of key input using the minimum number of keys.

Portable cordless phones are typically one of the products with keypads. Given the trend that multi-function miniaturization is required, the implementation of the technology that enables the use of various Hangul characters and the size of the keypad are often in conflict with each other. The same applies to public telephones and home telephones.

Hangul input requires many keys due to the characteristics of Hangul, but it cannot have one key for every Hangul on a limited size keypad. Public telephones, home phones, and portable cordless phones usually have 12 keys (eg 0-9, #, *) as default. If you want to use these 12 keys for Korean input, you can use multiple key combinations. This is inevitable.

1 is a view showing the structure of a conventional portable wireless telephone keypad.

In order to input Hangul using the 12 keys shown, two or three consonants or vowels are assigned to all keys except the lower three keys. Consonants and vowels assigned to the same key are selected according to how often they are combined into a single letter. It seems complicated because several consonants are drawn on one key.

When inputting Hangul using such a keypad, a user may not only feel inconvenience caused by a large number of key inputs, but also it is difficult and complicated to remember many key combinations.

Accordingly, an object of the present invention is to provide an apparatus and a method for inputting Korean characters using a minimum number of keys using a minimum number of keys.

The first invention for achieving the above object is that the Hangul input device, the vowel 'ㅣ', '·', the vowel 'ㅡ', the consonant 'b', the consonant 'ㄱ', the consonant ' A keypad having a consonant ',' consonant 'ㅅ', consonant 'ㄷ', 'consonant', and consonant 'ㅇ' and having at least one function key; When sequential input of 'a' and 'c' keys is detected, it is recognized as consonant 'ㄹ', and if sequential input of 'b' and 'a' keys is detected, it is recognized as consonant 'ㅁ'. If two consecutive inputs of a key are detected, it is recognized as a double consonant, and if it detects an input of the first function key following the input of 'ㅈ', 'ㄱ', 'ㄷ', 'ㅂ' or 'ㅇ' Correspondingly, the controller is configured to recognize the letters 'ㅋ', 'ㅋ', 'ㅌ', 'ㄷ', and 'ㅎ'.

According to the second invention for achieving the above object, the vowel 'ㅣ', '·', vowel 'ㅡ', consonant 'b', consonant 'ㄱ', consonant 'ㅂ', consonant ' In a device having a keypad assigned with ㅅ ', consonant' ㄷ ',' consonant ㅈ ', and consonant' ㅇ ', and having at least one function key, the Korean input method is used by the' a 'and' c 'keys from the keypad. A first process of recognizing a consonant 'ㄹ' when a sequential input of a key is detected; a second process of recognizing a consonant 'ㅁ' when a sequential input of a 'b' key and a 'b' key is detected from the keypad; A second process of recognizing a double consonant when two consecutive inputs of the same consonant key are detected from the keypad; and inputting an input of 'ㅈ', 'ㄱ', 'ㄷ', 'ㅂ' or 'ㅇ' from the keypad. When it detects the input of the function key, it responds to 'k', 'ㅋ', 'ㅌ', ㅍ is a, "" it characterized in that it comprises a fourth step of recognizing the heh.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, specific details such as the name of a specific function key (eg, 'Sen') are shown, which are provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific details. It will be obvious to those of ordinary skill in the art. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 is a diagram illustrating a structure of a keypad of a portable wireless telephone according to an exemplary embodiment of the present invention.

As shown, the three keys of the first row of the keypad having a 3 × 4 matrix structure are 'ㅣ', '·' and 'ㅡ', respectively. The three keys in the second line are ‘ㄴ’, ‘ㄱ’, and ㅂㅂ. The three keys on the third line are ‘ㅅ’, ‘ㄷ’, and ㅈㅈ respectively. The three keys on the fourth line are ‘ㅇ’, ‘OK’ and ‘sen’ respectively.

The 'confirmation' key is a function key that is reserved for use in other purposes, such as completion of a Korean input afterwards, and the 'sen' key is a function key for input of the Takum series.

The basic input method of the vowel using the keypad as described above is the same as the known 'Cheonjiin' algorithm. All three vowel combinations are possible with the three keys of the keypad, namely 'ㅣ', '·', and 'ㅡ' keys. The specific key combination form for each vowel is as follows.

ㅏ → ㅣ + · ㅐ → ㅣ + · + ㅣ

ㅑ → ㅣ + · + · ㅒ → ㅣ + · + · + ㅣ

ㅓ → · + ㅣ ㅔ → · + ㅣ + ㅣ

ㅖ → · + · + ㅣ + ㅣ ㅗ → · + ㅡ

ㅘ → · + ㅡ + ㅣ + · ㅙ → · + ㅡ + ㅣ + · + ㅣ

ㅚ → · + ㅡ + ㅣ ㅛ → · + · + ㅡ

ㅜ → ㅡ + · ㅝ → ㅡ + · + · + ㅣ

ㅡ → ㅡ + · + · + ㅣ + ㅣ ㅟ → ㅡ + · + ㅣ

ㅠ → ㅡ + · + · ㅡ → ㅡ

ㅢ → ㅡ + ㅣ

According to the invention, all consonants are made by two or fewer keystrokes (combinations). The specific key combination form for each consonant is as follows.

ㄱ → ㄱ ㄲ → a + a

ㄴ → ㄴ

C → c → c + c

D → a + c

ㅁ → ㄴ + ㄱ

ㅂ → ㅂ ㅃ → ㅂ + ㅂ

ㅅ → ㅅ ㅆ → ㅅ + ㅅ

ㅇ → ㅇ

→ → →

ㅊ → ㅈ + ‘sen’

ㅋ → ㄱ + ‘sen’

ㅌ → ㄷ + ‘sen’

→ → ㅂ + ‘sen’

ㅎ → ㅇ + ‘sen’

FIG. 3 is a diagram illustrating a keypad structure for explaining a method of inputting 'ㄹ' in FIG. 2. As shown in the arrangement of the keys, the user can easily remember the combination form of 'ㄹ'. In other words, if you look at the two keys at the same time in the vertical direction, it is easy to remember because it has the same visual effect as seeing one key, 'ㄹ'.

FIG. 4 is a diagram illustrating a keypad structure for explaining a method of inputting 'ㅁ' in FIG. 2. Looking at the two keys at the same time in the shaded horizontal direction, it is easy to remember because it has the same visual effect as seeing one key, ㅁ.

Adding a known algorithm such as 'Hangul Automata' to the combination of the consonants as described above enables the recognition of the base, thus enabling perfect Korean input.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention does not look complicated because several consonants are not drawn on one key, and it is easy for a user to understand a manipulation (key combination) method, and it is convenient to use.
