KR100265582B1 - The letter input method in communication terminal - Google Patents

Abstract

PURPOSE: A method for inputting characters in a communication terminal is provided to automatically convert an input order of consonants and vowels when the Korean alphabet is inputted. Therefore, it is possible to rapidly and conveniently input the Korean alphabet. CONSTITUTION: A processor successively assigns consonants to numerical keys from '1' to '9', and simultaneously successively assigns consonants. The processor assigns the consonant to a star key '*', and assigns consonants to a '0' numerical key. The processor sets up a pre-mode maintenance button to a pound key '#', and assigns a double consonant confirming button to numerical keys '2','5,''8'. Whenever the keys assigned the consonants and the vowels are inputted, the processor automatically maintains a consonant perceiving mode and a vowel perceiving mode, and alternately perceives the consonants and the vowels. If the pre-mode maintenance button is inputted, the processor maintains the previous consonant perceiving mode and the vowel perceiving mode. If the double consonant confirming button is inputted, the processor perceives the inputted double consonants.

Description

Character input method in communication terminal

The present invention relates to a communication terminal, and more particularly, to a character input method in a communication terminal capable of quickly and simply inputting a desired Hangul character when inputting Korean characters in the communication terminal.

There are various methods for inputting a character in a conventional communication terminal, but one of them will be described as an example. First, as shown in FIG. 2, when the English keyboard is assigned 'A', 'B', 'D', the 'A' is entered by pressing '2, 1' on the keypad. 'B' is inputted by pressing '2, 2', and 'D' is inputted by pressing '3, 1.' Here, 'A' character input button 2 and button 1 on the keypad By inputting button 2, A, B, C 'is selected, and then the first letter' A 'in' A, B, C 'is input by button 1 which is input. In case of 'B' character input, input button 2 and button 2 of keypad, which inputs button 2, A, B, C is selected and then enters' A, The second letter 'B' is entered in B and C. In addition, when the letter 'D' is input, buttons 3 and 1 of the keypad are input. E, F 'is selected, and the first letter "D" is inputted in "D, E, F" by the button 1 which is input next.

On the other hand, as shown in Figure 3, when entering the 'patent example' on the keypad assigned Hangul keyboard, as shown in Figure 3, select a character group containing the character for input and select the character to enter It is common to type similar to the input method. Enter '62', '# 1', and '11' on the keypad in order, and enter '72', '91' for 'Huh', '42', '92', Just type '# 2'. At this time, '*' key, which is the end key, must be entered for each character because of the characteristics of Hangul composed of initial, neutral, and final characters. In the case of the Hangul input system as described above, it is very cumbersome to input two consonants or vowels every time. To solve this problem, there is a method of inputting Hangul using a standard codebook. . In this method, a list is created by encoding a commonly used sentence, and a sentence is input when a code corresponding to a specific sentence is input. For example, if a user enters the code '1200' on a phone that remembers data about a sentence that says 'Please wait' and the code corresponding to the sentence is assigned to '1200', 'Please wait' is displayed in the conversion table. Is entered. In this method, since sentence units are encoded, long sentences can be input in a short time, but it is not easy to input a sentence that is not set in advance. .

As described above, in the conventional communication terminal, one consonant or vowel can be input only by operating the keypad twice at the time of inputting Korean characters. There is a problem that the probability is high and rapid input is not easy.

The present invention has been made in view of the above-described problems. When inputting Korean characters in a communication terminal, one consonant or vowel can be input by one keypad operation by automatically converting the input order of consonants and vowels. The purpose of the present invention is to provide a character input method in a communication terminal that can input Korean characters quickly and conveniently.

The present invention for achieving the above object, in the character input method in the communication terminal, sequentially assigns consonants from 'a' to 'ㅈ' one by one from '1' to '9' number keys At the same time, assign vowels from 'ㅏ' to 'ㅡ' one by one, assign consonants' ㅊ 'and vowel' ㅣ 'to' * 'key, and consonant' ㅎ ',' The process of assigning ㅌ ',' ㅋ ',' ㅍ ', setting the previous mode maintenance button on the' # 'key, and assigning the consonant confirmation button to the' 2 ',' 5 'and' 8 'numeric keys and; Automatically recognizing consonants and vowels alternately by alternately maintaining the consonant recognition mode and the vowel recognition mode each time the key assigned with consonants and vowels is input; Maintaining a previous consonant recognition mode or a vowel recognition mode when the previous mode maintenance button is input; When the double consonant confirmation button is input, it characterized in that it comprises a step of recognizing the input double consonant.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As illustrated in FIG. 1, a mobile phone according to an exemplary embodiment of the present invention generates an RF processor 21, a modulator / demodulator 22, a data compressor 23, and a dual tone multi frequency (DTMF). A unit 24, a codec 25, an audio amplifier 26, a liquid crystal display unit 27, a memory unit 28, a keypad 29, a processor 30, a microphone (MIC) and a speaker (SP) Is done.

The RF processor 21 receives the DTMF signal and the call message applied through the antenna ANT, outputs the DTMF signal and the call message to the modulator / demodulator 22, and outputs the DTMF signal and the call message received from the modulator / demodulator 22. Send through (ANT). The modulator / demodulator 22 demodulates the DTMF signal and the call message output from the RF processor 21, outputs the demodulated signal to the data compressor 23, and applies it from the DTMF generator 24 and the data compressor 23. The received DTMF signal processing and call message is modulated and applied to the RF processor 21. The data compression unit 23 compresses PCM (Pulse Code Modulation) data applied from the codec 25 into ADPCM (Adaptive Differential PCM) data, and applies the data to the modulation / demodulation unit 22 or the processor 30. The ADPCM data applied from the demodulation section 22 or the memory section 28 is decompressed into PCM data and applied to the codec 25. The DTMF generator 24 generates a DTMF signal corresponding to a key input from the keypad 29 under the control of the processor 30, and applies the DTMF signal to the modulator / demodulator 22. The codec 25 converts an analog audio signal applied from the audio amplifier 26 into PCM data and applies it to the data compression unit 23, and converts PCM data applied from the data compression unit 23 into an analog audio signal. The audio amplifier 26 is output to the audio amplifier 26 side. The audio amplifier 26 amplifies an analog voice signal applied from the codec 25 and outputs it through the speaker SP, and amplifies an analog voice signal applied from the microphone MIC and applies it to the codec 25. The liquid crystal display 27 displays the operation state of the phone and various kinds of information visually under the control of the processor 30. The memory unit 28 stores an operation program of the processor 30, and stores data applied from the processor 30 and a telephone number corresponding thereto. The keypad 29 has a plurality of keys for dialing a telephone number or for inputting and displaying various information. The processor 30 controls the overall operation of the telephone, which is applied from the data compression unit 23. The ADPCM data is converted into a predetermined data format and stored or updated in the memory unit 28, and the duplicated data is deleted in comparison with the data previously stored in the memory unit 28.

A method of inputting Hangul in the Hangul input mode in the portable phone configured as described above will be described with reference to the operation flowchart of FIG. 5.

The arrangement of the consonants and vowels in the keypad 29 of the telephone according to the present invention is as shown in FIG. 4, and each button accommodates the consonants and vowels in one button except for the 0 button. It can be seen. That is, the keypad 29 is arranged to include one consonant and a vowel for each of the numeric keys 1 to 9 and the '*' keys, and includes a '#' key to perform a function of a previous mode holding button. Whenever input, the consonant recognition mode and the vowel recognition mode are automatically maintained alternately to recognize consonants and vowels alternately, and when the previous mode maintenance button is input, the previous consonant recognition mode or vowel recognition mode is maintained. In addition, 'ㅎ, ㅌ, ㅋ, ッ', which is not frequently used, can all be assigned to the 0 key, and a character can be selected and used corresponding to the number of times the 0 key is input. For example, if you enter the 0 key once, 'ㅎ', if you enter 2 times 'ㅌ', if you enter 3 times 'ㅋ', if you enter 4 times, the character will be printed repeatedly.

When inputting Korean characters on the keypad 29 configured as described above, the following method is used. For example, when inputting a Hangul composed only of the initial and the neutral, such as 'gu', first, button 1 is input in the Hangul input mode (step S1). At this time, the first button of the keypad 29 is assigned a consonant 'ㄱ' and a vowel 'ㅏ', since it is the first input (step S2), the processor 30 sets the consonant recognition mode, and the double consonant confirmation button is Bar check whether the input (step S3), double consonant confirmation button will be described later in the double consonant input section, because the consonant confirmation button is not input recognizes the 'b' as normal consonants and changes the mode to the vowel recognition mode (Step S4). Afterwards, when the user inputs button 7 as the second input (step S6), the processor 30 is currently in the vowel recognition mode, so the vowel 'TT' is selected from the consonants 'ㅅ' and vowel 'TT' assigned to the button 7. By recognizing (step S7), the 'sphere' is finally output. Therefore, 'key' is output simply by 2 key inputs.

As another example, when inputting a letter composed of initial + neutral + final star, such as 'day', it is recognized as above. That is, the button 8 is input in the Hangul input mode (S1). At this time, the eighth button on the keypad 29 is assigned a consonant 'ㅇ' and a vowel 'ㅠ', and since the processor 30 is the first input, sets the consonant recognition mode (step S2), and confirms that the consonant confirmation button is input. In step S3, since the double consonant confirmation button is not input, the consonant is recognized as a general consonant, and the mode is changed to the vowel recognition mode (step S4). Afterwards, when the user inputs the '*' button as a second input (step S6), the processor 30 is currently in the vowel recognition mode, and thus the vowel is selected from the consonant 'vo' and the vowel 'ㅣ' assigned to the '*' button. 'ㅣ' is recognized and the consonant recognition mode is set (step S7). If the button 4 is continuously input by the user, this is the third input (step S8), and the processor 30 checks whether the '#' button is the previous mode holding button (step S9). By keeping the consonant recognition mode, the consonant 'ㄹ' and the vowel 'ㅕ' assigned to the button 4 recognize the consonant 'ㄹ' and finally 'day' is outputted (step S13). Therefore, 'day' is output simply by 3 key inputs.

On the other hand, when inputting twin consonants and double consonants, the following method is used, the output of the twin consonants according to the input of the button is shown in Table 1 below.

TABLE 1

Twin consonants output in accordance with the input of the key in the embodiment of the present invention

As can be seen in Table 1, the type of twin consonants are composed of a total of five, 'ㄲ', 'ㄸ', 'ㅃ', 'ㅆ,' ㅉ ', the present invention is shown in Figure 4 As can be seen, the double consonant elements are arranged only in the first column and the third column, and the second column is used as the double consonant confirmation button. For example, when inputting a word composed of a double consonant and a double consonant, such as 'Ke', first, a button 1 and a corresponding double consonant confirmation button 2 are simultaneously input in the Korean input mode (step S1). At this time, the first button of the keypad 29 is assigned a consonant 'a' and a vowel 'ㅏ'. Since the processor 30 is the first input (step S2), the consonant recognition mode is set and the double consonant confirmation button is input. Bar (step S3), the double consonant confirmation button is input at the same time, so the 'a' is recognized as a twin consonant and outputs as 'ㄲ' and the mode is changed to the vowel recognition mode (step S5). Afterwards, when the user inputs the button 3 as the second input (step S6), the processor 30 is in the current vowel recognition mode, so the vowel 'ㅓ' is selected from the consonant '' 'and the vowel' ㅓ 'assigned to the button 3. Is recognized and the mode is set to the consonant recognition mode (step S7). The currently selected word is 'off' and the vowel 'ㅣ' is selected to output the double vowel 'ㅔ'. Currently, the consonant recognition mode, the user inputs the '#' button assigned as the previous mode maintenance button as the third input. By inputting (step S8). The processor 30 changes the current consonant recognition mode to the vowel recognition mode which is the previous mode (steps S9 and S10). Afterwards, when the user inputs the '*' button, the processor 30 recognizes the congregation 'ㅣ' among the consonants 'ㅊ' and the collection 'ㅣ' assigned to the '*' button because the current collection recognition mode (step). S11) Finally, "y" is input (step S12). In other words, in the case of entering 'to', the buttons that are input are summarized as '1' + '2', '3', '#', and '*'. Here, '1' + '2' means pressing button 1 and button 2 simultaneously.

As described above, the present invention, when inputting Hangul characters in the communication terminal, automatically converts the input order of consonants and vowels so that one consonant or vowel can be input by one keypad operation. You can enter text.
