Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an Hangul input device, and more particularly, to miniaturization of various electronic devices, especially devices, including personal PCs, PDAs, hand-held terminals, set-top boxes, mobile phones (GSM, CDMA), and car navigation. Accordingly, the present invention relates to an input device capable of quickly inputting Hangul, which can be applied to a PDA having limited input space.

The Hangul input device according to the present invention can be composed of a total of 13 keys by extracting 9 keys condensed 14 Hangul consonants + 3 Hangul vowels + 1 double consonant key. In addition, the user may conveniently input the Hangul in the same order as the Hangul writing method without the need for special conscious memorization. This means, for example, that when the user enters "ga", the user manually writes Hangul by hand only through "1 + 2 + 9 + 8 key input (see key input representation)". There is no need to memorize because the input method is the same. In addition, this is in line with the fact that Korean characters can be conveniently input in the same order as the Korean writing method. In addition, it is possible to input in a confined space, and it is a system that inputs twin consonants using a twin consonant button (key) rather than the conventional consonant input system of consonant + consonant. In addition, in systems using PDAs or other stylus pens (touch screen type), the system can directly input not only the stylus pen but also a finger.

Hangul is different from each phoneme, that is, English, French, German, and Japanese except for Chinese characters. In other words, Jong-jong has two-dimensional writing system that is composed of syllables.

In the case of inputting a character into an electronic device, a simple one-dimensional character can be completed by a relatively simple character input protocol because a single word is completed only by the phoneme order. For example, the word apple is a one-dimensional word. When you enter the letters a + p + p + l + e one by one, the input method is completed. However, in the case of Hangul, not only two-dimensional arrangement is needed, but when two or more consonants except Lee Eung are repeated, as in the examples of “squeeze”, “gyekki”, and “chigi”, each consonant More complex protocols are required because there are 14 consonants and theoretically infinite vowels, which must be determined how to place them.

<9> With the rapid development of electric and electronic technology, various methods such as CDMA, PCS, TDMA, GSM, AMPS, IMT-2000, mobile phones, PDAs (OS with Windows, Linux, Palm, etc.), pagers, small As the desire to express characters in various electronic devices such as game consoles, remote controls, set-top boxes, cameras, and home appliances increases, the necessity of inputting characters continues to increase. In response to this, various methods (devices) for inputting Hangul have been developed, especially in PDAs and smart phones, which have limited input space. The initial input device is the simplest. When the Hangul input mode is displayed, all the consonants (consonants) are displayed on the LCD, and the user moves the cursor to select the desired consonant. It was a way to determine one syllable by selecting the desired vowel. (Korean Patent Publication No. 99-24321). Later on, vowels were developed and settled by extracting the basic morphemes of each vowel, placing ㅡ, ㆍ, ㅣ on three buttons and entering all vowels through their permutations. Republic of Korea Patent Publication No. 97-2558).

<10> Consonant input method (device) is largely 1. keyboard input method on PDA. This is a method of placing consonants and vowels on one screen like a computer keyboard on a PDA where space is acute. 2. A method of arranging two or three consonants in one key and determining one consonant corresponding to the number of times a specific key is pressed within a predetermined time period (continuously arranged), 3. Only the consonants that are the core in shape Are arranged in one key each and 2 or 3 function keys are added to select the consonant that is not arranged by pressing the key where the consonant in shape is close and pressing the function key within a predetermined time. Function key utilization) and method to extract consonants morphologically, extract shapes (or symbols) that are common in shape, place them on each key, and press these keys one to several times to select consonants by permutation ( Figure sequence).

In the keyboard-based input system, the total number of keys exceeds 20. But touch screen on PDA is limited space. Therefore, as all consonants and vowels are placed in a limited space, each button is small and it is inconvenient to input, and it is common to press other buttons. In addition, the size of each button is small, so it is impossible to directly input by hand.

<12> The continuous arrangement type is not convenient because it is printed with a plurality of phonemes on a single key, which not only confuses the user but also keeps an eye on the change of the phonemes displayed on the display device as a key is pressed. There is a problem.

The function key utilization type is disclosed in Korean Patent Publication Nos. 00-42231, 00-49346, 00-49347, and 00-54571. The technique of these materials assigns 6 to 7 representative consonants to one key, and each of the three vowel morphemes or 6 representative vowels is placed on 5 to 6 new keys and 1 to 3 function keys. The keyboard where I placed is applied.

Phonemes not displayed on the <14> key are determined by selecting a predetermined phoneme displayed on the key and pressing a predetermined function key a predetermined number of times within a predetermined time. The figure sequence type is a method of extracting figures (or symbols) that are common in form, placing them on each key, and pressing these keys one to several times to select consonants based on the permutation.

Another input method is to assign all vowels to the keyboard. I have placed all the vowels in ten keyboards and duplicated the default consonants to each keyboard. Therefore, the vowel input part has an advantage of being able to input faster than other input devices. In addition, by placing a relatively large number of phonemes, it is relatively superior in terms of recognition. However, since consonants and vowels are simultaneously arranged on one keyboard, continuous letters cannot be input, so a moving key must be input during input.

Unlike the conventional input system, which is designed to input with one hand, there is a system that can input with both hands. For example, the "1" is arranged in the number 1 keyboard, and when "1" is selected while pressing the "*" button, "a" is adopted. Therefore, it is inconvenient to input while traveling by subway or bus.

As described in detail above, the Hangul input device according to the present invention is a system that can be easily permutated, sequentially input in the state of Hangul consonants and Hangul vowels. Accordingly, the user does not need to memorize specially and can conveniently input Hangul in the same order as handwriting. In addition, since all Korean characters can be input with a limited number of keys (buttons), it is expected to be applied as a small keyboard or keypad to miniaturized and multifunctional electronic devices such as mobile phones.

<20> In addition, the speed Hangul input system is approximately 1.89 hits / character, which is a consonant stroke, 1.84 strokes / character, Speed Hangul input system is 1.84 strokes / character, the overall average stroke is 2.500 strokes / character, and Speed Hangul input system is 2.425 strokes / character. In the method, since multiple consonants are arranged on one button, the batter cannot be beaten, whereas Speed Hangul input system can be battered by placing a single phone on one button. This means the speed and accuracy of the input. In addition, when using the consonant button, two to three inputs are possible only when inputting the same button three or four times as usual. For example, if you input "ㅆ", you can enter the consonant by entering only the ㅅ (button 7) + double consonant button. Therefore, the actual overall average input speed is significantly ahead of the Speed Hangul input system.

<21> It is to solve the problem of the Hangul input method (device), and the user does not need to memorize specially, and the consonants 14 consonants 9 (-, |, ㅁ, ㅅ, ㅇ, ㄹ, ㅋ It is a Korean input type by using ㅌ, ㅍ) button (key), 3 vowels (ㅡ, ·, ㅣ), and double consonant button. For the purpose of

A Hangul input device including a Hangul consonant input unit and a Hangul vowel input unit as an essential component. This maximizes the number of strokes by placing all the keys in a timely manner, especially on a mobile phone (this gives the Chonjiin the opportunity to enter more quickly using 13 buttons compared to using only 10 buttons). On the PDA, it is useful in the situation where the input can be made by the touch pad without requiring a key. Nine buttons condensing 14 Hangul consonants and Hangul vowels (ㅡ, ㆍ, ㅣ) are also arranged in sequence so that users can see them easily, input them with minimal education, and write them naturally as if they were handwriting. I can go out. This is illustrated in (FIG. 1) and (FIG. 2), respectively.

<Table 1> is a collection of input signal sequences of consonant or final input keys and consonant phonemes. (Table 2) shows input signal sequences of neutral input keys and corresponding vowel phonemes.

Also, (Example 1) is an example in which two consonants and vowels are combined to form a word.

The user does not need to memorize specially and can conveniently use Hangul in the same order as handwriting. In addition, all Hangul characters can be input with a limited number of keys.

Application or porting is expected with a small keyboard or keypad.

<27> Also, unlike the Cheonjiin method, the vowels are on buttons 7,8, and 9 so that convergence with the consonants can be input faster, and battering is also possible. do.
