    Text input method of communication terminal {TEXT INPUTTING METHOD OF MOBILE STATION}
    [14] The present invention relates to a character input method of a communication terminal, and more particularly, it is possible to input various characters to a wired / wireless communication terminal such as a mobile phone and a mobile phone more quickly and easily to facilitate text communication with a communication device. The present invention relates to a character input method of a communication terminal.
    [15] In the recent information age, wireless communication terminals (cell phones, mobile phones) with keypads for entering numbers so that anyone can easily talk with the other party anytime and anywhere, and wired communication terminals (telephones) at home or at work Had each).
    [16] Furthermore, as described above, a wired / wireless communication terminal for transmitting / receiving voice signals is also being developed to transmit / receive even texts and videos by accessing the Internet.
    [17] Looking at an example of such a conventional character input method, a total of 12 keys are used for character input by combining a special numeric keypad such as "0" to "9" and special characters such as "*" and "#". At this time, the characters to be input are "Chinese consonants: 24 characters" and "English: 26 characters", since the number of the available keys exceeds 12 (12). A specific character is selected according to the number of times the key is repeatedly pressed.
    [18] In other words, when "a", "a", "a", "a", "a", "a", and "a" are pressed, the key is pressed once and "a" is entered. If "c" is entered.
    [19] However, in order to input a relatively large number of characters (Korean collection: 24 characters, English characters: 26 characters) with a communication terminal having a keypad of limited numbers (0 to 9), the corresponding number keys must be pressed several times (about 3 to 5 times). As a result, it is difficult to input normal characters, and there is a problem in that the time required for entering characters becomes long.
    [20] Accordingly, the present invention is to solve the above-mentioned conventional problems, the object is to enable the input of various characters more quickly and easily by a simple key input up to one or two times in a communication terminal such as a mobile phone and a mobile phone The present invention provides a text input method of a communication terminal to facilitate text communication with a communication device.

    [32] Here, the key press detection means 30 includes piezoelectric sensors that correspond to the plurality of key buttons 11 in a ratio of 1: 1, and presses the pressure of the key button 11 to "strong, weak", respectively. It consists of a key pressure sensing unit 30 for detecting the pressure divided into the stages of "strong, medium, weak", as shown in Figure 3 divides the voltage or current generated by the pressing pressure into a range of intervals If a voltage or current occurs within the range, it is detected and recognized as a character of a specific step.
    [33] In addition, as another configuration of the present invention, the key press detection means 30 includes a timer for counting the time from the moment when the plurality of key buttons 11 is pressed to the end, the key button 11 ) Is composed of a key press time sensing unit 40 which detects the time by dividing the pressed time into "long, short" or "long, middle, short" stages, as shown in FIG. The length is divided into a range of intervals, and when a press time occurs within the range, it is detected and recognized as a character of a specific step.
    [34] In addition, as another configuration of the present invention, as shown in Figure 5, the key press detection means 30 is formed with a contact point Q on one side of the key button 11, the vertical movement of the key button 11 In the guide 12 for guiding the position of the contacts P1, P2, P3 corresponding to the contact Q in a "high, low" or "high, medium, low" stage, the top and bottom of the key button 11 A key contact position detection for detecting a contact position at which the key button 11 is pressed step by step so that a signal of each contact P1, P2, P3 in contact with the contact Q is transmitted to the control unit 60 according to the movement position. It can comprise with the part 50.
    [35] That is, when "a" is input by the character array shown in FIG. 7, the number "1" key button 11 is pressed down to be brought into contact with the contact point P1, and when the "b" is input, the number "1" is entered. By pressing the key button 11 deeply so that the contact point Q comes into contact with the contact point P2, desired characters can be input quickly and easily. In addition, in the case of inputting "a" by the character arrangement shown in FIG. 8, the number "1" key button 11 is pressed low, and in the case of entering "b", the number "1" key button 11 is entered.

Can be.
    [38] 7 to 9 are views showing various embodiments of the character arrangement of the keypad according to the present invention. As shown in Figs. 7 and 8, the key button 11 has a sound of Korean characters recorded on its surface. To arrange the possible input of "ㄱ, ㄷ, ㅂ, ㅅ, ㅈ" so as not to overlap each numeric key, if the numeric key is entered once, according to the pressing pressure of the corresponding key, time or contact position Recognizing a character, when the same numeric key is input twice in a row, the control unit 60 does not detect the state in which the key button 11 is pressed step by step immediately "ㄲ, ㄸ, ㅃ, ㅆ , ㅉ ".
    [39] In addition, the control unit 60, when inputting the sound of the Korean character through the key button 11, by combining a specific button of the button is not recorded with a button recorded with "ㄱ, ㄷ, ㅂ, ㅅ, ㅈ" When pressed, the sound of "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ" is input. That is, when a key button (for example, "*" or "#") 12 other than the numeric key on which characters are recorded is pressed in combination with a key on which "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ" is recorded, Depending on whether the other key button 12 is input or not, the sound of "않도록, ㄸ, ㅃ, ㅆ, ㅉ" may or may not be input.
    [40] In addition, as shown in Figure 9, when entering the case of alphabetic letters, when pressing a specific button in combination with a button that is recorded alphabet of the alphabet is not recorded, the uppercase or lowercase letters are entered. That is, when a key button (for example, "*" or "#") 12 other than the numeric key "0" on which an alphabet is not written or the numeric key on which a letter is written is pressed in combination with a key button on which an alphabet is recorded, is pressed. It can also be entered case sensitive.
    [41] Such a character array can be variously implemented, and in the present invention, various characters such as Korean, alphabet, and one letter can be input quickly and easily. In particular, one time for a terminal sound and two key presses for a sound or a double consonant sound. You can quickly and easily enter the corresponding character.
    [42] In addition, although not illustrated here, in the case of a sound or a double consonant sound (by pressure, time, and position) according to the arrangement of characters according to the gist of the present invention, it may be input at a time, and the same is true of a short vowel and a double vowel. .
    [43] Hereinafter, the operation of the present invention configured as described above will be described in more detail by way of example using a pressure method. Here, the arrangement state of the key buttons will be described with reference to FIG.
    [44] First, when three characters are recorded in one numeric key button 11, as shown in FIG. 8, the pressing pressure of the key button 11 is divided into three stages to recognize the characters.
    [45] That is, the user presses the key button 11 in which the number "1" is recorded in order to input the letter "car", but the pressure of the key button 11 is hardened (strong) so that the "ㅋ" is inputted. (S101).
    [46] Thus, as shown in Fig. 2, the key button 11 generates the inherent DTMF signal " frequency Aa " of the number " 1 ", and the key pressure detection unit 30 is pressed by the piezoelectric sensor. To generate a voltage or current signal (S102).
    [47] Here, the generated voltage or current corresponds to the case of " strong " as shown in FIG. 3, so that a voltage or current of 5 V or 5 mA is generated.
    [48] On the other hand, the recognition of the numbers "0 to 9" is to be recognized by using the normal inherent DTMF signals (frequency A to D, frequency a to c), so a detailed description thereof will be omitted.
    [49] Therefore, the control unit 60 determines that the key button 11 of the number is "1" according to the DTMF signal recognized by the DTMF recognition unit 20 (S103), and determines the voltage or current generated by the pressure. Compare / determine with the pre-stored step (S106 ~ S109).
    [50] That is, the state in which the button is pressed is divided into "strong, weak" or "strong, medium, weak" according to the pressure, and the corresponding character is stored in advance, and this is compared with the detected specific pressure level. By determining the corresponding character, in this case, since the specific pressure detected by the key pressure sensing unit 30 corresponds to "strong", it is determined that the character "ㅋ" corresponding to this step is input.
    [51] Thereafter, the corresponding character is displayed on the display unit 50 and the input of the next character is received (S110).
    [52] Thereafter, in the same manner, the user inputs and completes the letter "car" by lightly pressing the key button 11 on which the number "6" is recorded and entering "ㅏ".
    [53] As described above, in order to input the letter "C" in the related art, it is possible to input by pressing the key button at least three to five times according to the character arrangement, but in the present invention, only two times (one consonant and one vowel) are pressed. By inputting desired letters quickly and easily, it is possible to use text communication more easily.
    [54] In addition, in the case of inputting the old sound, in the present invention, the possible input of the sound of the Korean characters recorded on the surface of the key button 11 is possible so that the "a, c, ㅂ, ㅅ, ㅈ" is not duplicated in each numeric key. Since it is arranged, when the same number key is input twice in a row, the controller 40 recognizes that the button is pressed as a step "ㄲ, ㄸ, ㅆ, ㅆ, ㅉ" without detecting the state in which the button is pressed step by step. In the case of the old sound, it can be input quickly and easily like general characters (S103 to S104).
    [55] In addition, in the case of Bokja (for example, "ㄺ"), the corresponding characters are input in the order of "d", "a", and displayed in a combination thereof.
    [56] Of course, in the case of the old sound, as described above, two consecutive inputs of the same numeric key may also be judged as the sound. Alternatively, by inputting the corresponding characters in order, such as the input of the Bokjaja, for example, in the case of "ㄲ" It is also possible to display "약" by entering the key "1" lightly twice and entering the "a" and "a".
    [57] In addition, the control unit 60, when inputting the sound of the Korean character through the key button 11, by combining a specific button of the button is not recorded with the button recorded with "ㄱ, ㄷ, ㅂ, ㅅ, ㅈ" When pressed, the sound of "ㄲ, ㄸ, ㅃ, ㅆ, ㅉ" is input. That is, when a key button (for example, "*" or "#") 12 other than the numeric key in which a letter is recorded is pressed in combination with a key in which "a, c, ㅂ, ㅅ, ㅈ" is recorded, Depending on whether the other key button 12 is input or not, the sound of "않도록, ㄸ, ㅃ, ㅆ, ㅉ" may or may not be input.
    [58] In addition, when inputting a case-sensitive case of an English letter, a case in which a specific button is pressed in combination with a button in which an alphabet is recorded is inputted so that an uppercase or lowercase letter is distinguished. That is, when a key button (for example, "*" or "#") 12 other than the numeric key "0" on which an alphabet is not written or the numeric key on which a letter is written is pressed in combination with a key button on which an alphabet is recorded, is pressed. It can also be entered case sensitive.
    [59] As described above, the method using the pressing pressure of the key button has been described as an example. As shown in FIG. 4, the character may be determined by dividing the key press time step by step. As shown in FIGS. 5 and 6, Characters may be determined by dividing the position of the contact point by stage at the time of key press, and various implementation methods such as the above are different from the configuration of the detection and determination criteria, and the specific gist of the present invention is that the key press state is staged. Since the act of sensing is almost the same as that described in this embodiment, the detailed description thereof will be replaced with the above-described drawings and configuration description and will be omitted here.
    [60] The present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Such changes are intended to fall within the scope of the claims set forth herein.
    [61] As described above, according to the character input device of the communication terminal according to the present invention, in order to input a specific character, it was possible to input by pressing a key button at least three to five times in accordance with the character arrangement in the prior art, Regardless of arrangement, the letters can be entered more quickly and easily by key press of a maximum of one to two times (one consonant and one vowel), so that text communication can be easily used.
    [62] In addition, two consecutive inputs of the same numeric key may be judged as sounds, or other characters may be sequentially inputted like the input of a consonant sound, and thus the input method may be more diverse and simpler.
