Abstract

PURPOSE: An apparatus and method for inputting Hangul through a numerical key pad is provided to allow a user to easily input Hangul in a mobile phone, an SMS terminal, a PDA, electronic organizers, an ATM by disposing consonants and vowels at 9 number keys except for 0 on the number key pad. CONSTITUTION: Consonants and vowels are allocated to the number keys of 1-9. Output of a consonant is determined according to the number of times of pressing a key and output of a vowel is determined by simultaneously pressing '0' or a function key or pressing shortly after pressing a corresponding vowel-allocated key. Accordingly, Through the contracted key board consisting of only number keys, as well as the key pad of the existing mobile phone consisting of 12 keys including the function keys, Hangul can be inputted, and since every consonant corresponds to the numbers of 1 to 9, memory of phone numbers through a company name or a person's name can be possible for Hangul.

Description

Input method and input method through the numeric keypad {The way of inputting Korean Character through Numeric Keypad}

The present invention relates to an apparatus and method for inputting Hangul by appropriately placing consonants and vowels of Hangul on a numeric keypad.

With the development of communication and information technology, various types of portable communication terminals have been introduced. These terminals generally use the numeric keypad as a character input device because of the size limitation. With the development of the terminal itself, various Hangul input methods that can be used for these numeric keypads have been devised and developed. In particular, in the case of mobile phones, Hangeul input devices are the most widely used as can be seen through the rapid increase in the use of text services. As can be seen from the case of a mobile phone, the importance of a simple and easy to learn Hangul input device is increasing day by day.

Many Korean input methods have been devised so far, but the most used ones are the 'Cheonjiin' and 'Sejong' Hangeul input methods. Among them, the 'Cheonjiin' input method reduces vowel assignment keys to three on the keypad by applying cheon (·), ji (ㅡ), in (ㅣ) samjae, the basic principles of Hangeul creation. By doing so, it can be said that the idea of Hangul input method has been fundamentally changed. However, by assigning consonants and vowels to keys separately, the number of key presses increases when a specific consonant and vowels are input, and the final letter of the preceding letter and the first letter of the trailing letter are assigned to the same key. The same is true of the Sejong Hangul input method. Furthermore, since the consonants do not correspond to all the numeric keys on the numeric keypad, they do not have the function of making the phone numbers easy to understand and remember by matching the names and numbers commonly used in English culture.

According to the present invention, Hangul can be input more conveniently and intuitively by allocating consonants and vowels of Korean characters to numeric keys 1 to 9 except for the number '0' and function keys ('*', '#') on the numeric keypad. Its purpose is to make it possible. In addition, all 19 consonants in Hangeul correspond to the numeric keys so that the phone numbers can be displayed in Korean. For example, in the case of Korea Telecom, it can be displayed as "OOO-Korea Telecom (8147)" (see Fig. 1).

According to the present invention, most of the consonants of Korean characters can be displayed by pressing a key once or twice. 'ㅋ', which is judged to be the least used, is allocated to the number 8 key with 'ㅇ' and 'ㅎ' arranged together. Only in this case, the key is pressed three times (in the case of FIG. 1). On the other hand, the vowel is displayed by pressing one of the numbers '0', '*' and '#' keys and then pressing the corresponding vowel key. Alternatively, press the corresponding vowel key and press one of the '0', '*' and '#' keys to display the vowel. This makes it possible to input Hangul quickly and easily when typing with one hand or with both hands. In the present invention, consonants and vowels are assigned to the numeric keys, and the numbers '0', '*' and '#' are control keys, and the consonants and vowels are assigned by assigning the same role as the [SHIFT] key on a general computer keyboard. Because it is used to distinguish the existing Hangul input device, the problem that occurs when the first and the same type is often the same, the delay of input is frequent, and the complicated inconvenience of having to press the vowel key several times to form the vowel Resolved. For example, if you enter the sentence 'excellent Hangul input' without spaces, you need to press the key three times to use the existing so-called 'Cheonjiin' Hangul input method. ('0', '*', '#' key and pressing the vowel key at the same time), only 29 times, if you enter with one hand (press the vowel key, then press '0', '*' In the case of pressing the '#' key, it is similar to 40 times, and in this case, it is much easier to input since it is 11 times to repeatedly press the key to switch to the vowel. In addition, the present invention is intuitive because the arrangement of the Hangul alphabet, particularly the arrangement of vowels, is similar to that of a general computer keyboard, compared to other Hangul input methods.

Another technical problem to be achieved by the present invention is to correspond to the number of the phone number to the consonant of the Hangul so that it is easy to remember the Hangul name and name. Until now, Hangul trade name, which can be easily displayed in correspondence with numbers, has been used in a limited number of industries. For example, 'Isaisa (2424)' or 'Quickly (8282)' can be expressed in numbers depending on the similarity of pronunciation, but it was not related to the Korean input device. However, according to the present invention, it can be easily displayed as a phone number through a Korean name or a name. For example, Korea Telecom can be represented as "OOO-Korea Telecom (8147)" and the Patent Office can be represented as "OOOO-482". This function can be useful when the internet connection through the portable terminal is increased. It is expected that the portable terminal uses an input device consisting of numbers and a few control keys due to the size limitations, so that Internet URLs are often made into numbers. If such a numeric URL can be easily displayed in Korean, it will be advantageous for promotion. For example, the JPO may make an Internet URL for a portable terminal "http://www.482.go.kr" and display it as "http://www.KIPO.go.kr". In the case of a text message service company, the URL may be referred to as "http://www.59579.com" and "http: //www.text message.com".

1 and 2 are examples in which consonants and vowels of Korean characters are arranged on a numeric keypad according to the present invention.

Figure 3 is a flow chart showing a preferred embodiment of the Hangul input method according to the present invention.

The present invention assigns 19 Korean consonants to the numeric keys of 1, 2, 3, 4, 5, 6, 7, 8, and 9, and assigns basic vowels (ㅏ, ㅓ, ㅣ, ㅗ, ㅜ, ㅡ) to general. Assign the upper number keys on the keypad, that is, the number keys 1, 2, 3, 4, 5, and 6, and assign ㅐ and 에 to the lower number keys except 7, that is, 7 and 9. 1 is an embodiment in which consonants and vowels are arranged according to the present invention. FIG. 2 is an embodiment in which the consonant arrangement is slightly changed with reference to a consonant arrangement of a 2 beol Hangul keyboard of a computer generally used. The consonant arrangement of the two examples is somewhat different, but the basic construction principle is the same. 3 is a flowchart illustrating a preferred embodiment of inputting consonants and vowels and generating Korean syllables according to the present invention. The configuration of the present invention will be described in detail as follows.

Phoneme generation

The basic consonants (a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ) and the sounds (으로, ㄸ, ㅆ, ㅃ, ㅉ) represented as pairs of each basic consonant are assigned to the same key and used frequently. Has been assigned to the other low consonants (ㅌ,, ㅌ, 할당, ㅎ) to other basic consonant keys, so that you can intuitively know the arrangement of the phonemes as you type. According to this consonant arrangement, most consonants can be entered by briefly pressing the numeric key once or by pressing twice. According to the present invention, all the consonants including the old sound are allotted to nine numeric keys 1 to 9, so most consonants can be input by pressing the key twice or less. However, in the case of the harsh sound 'ㅋ' which is judged to be low in frequency, it is input by three key presses. Therefore, in the Hangul input device according to the present invention, the consonant generation is determined according to the code value assigned to the corresponding key and the number of key presses.

The consonants assigned to each key are determined by the main processor in accordance with the number of key presses. Of the 9 consonants assigned to each number key, the first 9 consonants placed in front of each group press the key once, except for 'ㅋ'. The code value is assigned by pressing (see the 'phoneme generation' section of FIG. 3). [Table 1] is a table showing the manner in which all the consonants of the Hangul pressing the assigned key in accordance with the arrangement illustrated in FIG. In the main processing unit, if the next input value is a vowel, a consonant assigned to another key, a number or special character key input, or a certain time delay, the previous key input is analyzed to determine the consonant, and then the temporary memory (buffer ) To store the consonant code.

Vowels assign default vowels (ㅏ, ㅓ, ㅣ, ㅗ, ㅗ, ㅡ) to the upper numeric keys 1 through 6. All Korean vowels consist of six basic vowels assigned to the upper numeric keys in the present invention. Therefore, all vowels can be entered by operating the numeric keys 1 to 6. In addition to the six basic vowels, the frequently used vowels ㅔ and ㅔ are assigned to individual keys to reduce the number of key presses so that they can be entered. ㅐ and ㅔ can be entered by pressing the corresponding key once, or can be entered as a combination of basic vowels. According to the present invention, to enter a vowel, a number '0' or a function key ('*', '#' Press one of the ')' keys or press the corresponding key and then press one of the numbers '0' or a function key ('*', '#'). In this case, two or more of '0', '*' and '#' may be simultaneously pressed. This function is to increase the convenience when typing Hangul at a high speed (see the 'phoneme generation' section of Figure 3). The vowel vowels (ㅑ, ㅕ, ㅛ, ㅠ) can be expressed as a combination of the vowel 'ㅣ' and the vowel according to the principle of pronunciation composition, and can be entered by pressing the vowel twice. For example, if you input 'ㅑ', you can also input a combination of 'ㅣ' and 'ㅏ'. You can also input by pressing 'ㅏ' twice consecutively. Therefore, in the Hangul input device according to the present invention, the vowel input can be selected according to the user's input habit, and the method can be made flexible. [Table 2] shows this as a table, and summarizes the way in which all the vowels of Hangul are pressed according to the arrangement illustrated in [1].

In the main processing unit, when a consonant is input, when a value that is out of the Hangul vowel discipleship is input (for example, when 'ㅣ' is entered after 'ㅙ') or when a numeric and special character key is entered. If it is an input or if a certain amount of time is delayed, the previous keystroke is analyzed to determine the vowel, and the vowel code is stored in temporary memory (buffer).

Generation of syllables

In the present invention, syllables are generated by combining values stored in a temporary memory. In the main processor, when a consonant (consonant) neutral (vowel) or a consonant (consonant) neutral (vowel) consonant is consecutively inputted, the syllable is determined by combining the consonant values and vowel values that are input immediately before and stored in the temporary memory. do. Even when numeric and special character keys are entered or delayed for a certain time, syllables are determined by combining consonant values and vowel values that are input immediately before and stored in temporary memory. At this time, syllables that are not used in unit phonemes or everyday life (for example, Even if ')' is stored in the previous temporary memory, it is determined by the user's intention when a certain time is delayed or a number, a special character, or a completed syllable is input next. By doing so, it was difficult to type in the existing Korean input device using the numeric keypad. Syllables such as' can be displayed. This process is repeated after one syllable is created. The Hangul input described above is shown in FIG. 3 in the order of information processing. The 'phoneme generation' part of FIG. 3 shows the processing of the input and keycode analysis of the consonants and vowels described above, and the 'syllable generation' part generates syllables by combining the input consonants and vowels and extracts the consonants of the trailing characters. It shows the information processing process that returns to the stage just before the 'collection and neutral determination' on the flowchart.

Numbers and special characters

In the present invention, a space (one forward or corresponding to a computer keyboard space input value) and one space backward may be displayed according to a key operation. '*' And '#', which were used as control keys when entering Korean characters, display long 'one space backward' and 'one space forward' respectively when long pressed. In addition, the display of the number is displayed by pressing and holding the corresponding number key.

As described above, in the present invention, all the consonants of the Hangul are arranged and assigned to the numeric keys 1 to 9 so that the basic consonants (a, b, c, d, ㅁ, ㅂ, ㅅ, ㅇ, ㅈ) are pressed once. Input is possible, and most of the old and rough sound consonants can be input by pressing twice and the consonant ('ㅋ' in the example of the present invention), which is judged to have the lowest frequency of use, can be input by pressing three times. Therefore, the location and input of consonants are intuitive. Basic vowels (ㅏ, ㅓ, ㅣ, ㅗ,, ㅡ) and 'ㅐ' and 'ㅔ' are arranged and assigned on the numeric keypad with consonants to operate with the control keys to enter all vowels within a few keystrokes. This is possible. Therefore, Hangul can be more easily input in a terminal having a numeric keypad as a main input device, that is, a mobile phone, a general phone, a PDA, an electronic notebook, and the like. In addition, in the present invention, since all consonants are assigned to the numeric keys except '0', the phone number can be represented by the Hangul name and name. This has the effect of memorizing the phone number more easily.
