Description

Character input method of mobile communication terminal {METHOD FOR INPUTTING LETTER IN A MOBILE PHONE}

The present invention relates to a character input method of a mobile communication terminal, and more particularly, to a character input method of a mobile communication terminal that allows a user to input characters conveniently and accurately.

Recently, due to the development of mobile communication technology, the number of users of mobile communication terminals such as mobile phones and PCS phones has been increasing rapidly. Accordingly, various services available through mobile communication terminals have been provided. Accordingly, the necessity of inputting characters, particularly Korean characters, in a mobile communication terminal is increasing.

In particular, unlike 2G mobile communication (2G cellular and PCS), which is voice-oriented mobile communication, it is called next generation mobile communication or 3rd generation mobile communication system (3G), and is a multimedia mobile communication that can transmit and receive voice and video data. If IMT-2000 is commercialized, character input function through mobile communication terminal will become more important.

The Korean input method of the conventional mobile communication terminal may be Samsung's 'Cheonjiin' or LG's 'Naratgle 2000'.

1A and 1B are diagrams illustrating a mobile phone dial for a Korean input method according to the prior art. Figure 1a is a view showing the dial of a mobile phone for the Hangul input method of the conventional 'Cheonjiin' of Samsung. 'Cheonjiin' consists of all vowels in the combination of thousand (·), ji (ㅡ), and phosphorus (ㅣ). The vowel 'ㅏ' combines 'ㅣ' and '·', and 'ㅑ' is 'ㅣ' You will enter a corresponding vowel using a combination of ',' and '·'. Consonants are assigned two consonants to a button, press the button once or twice to enter the consonants, and '된', 'ㄸ', 'ㅃ', etc., three times in a row to enter.

'Naratgle 2000' is a basic consonant of 'ㄱ', 'ㄴ', 'ㄹ', 'ㅁ', 'ㅅ' and 'ㅇ', and the 'overwrite' function allows input of other consonants. For example, the consonant 'ㄷ' is entered as a combination of 'b' and 'overwriting', and 'ㅈ' is entered as a combination of 'ㅅ' and 'overwriting'.

However, this conventional Korean input method divides the number buttons from '0' to '9' and allocates vowels and consonants to them so that it is inconvenient in the number and time of button input by putting several functions in one button. Had a ham.

Accordingly, an aspect of the present invention is to provide a character input method of a mobile communication terminal, which enables a user to reduce the number of button inputs and input characters accurately.

According to an embodiment of the present invention for achieving the above technical problem, in the character input method of the mobile communication terminal, if the character key button included in the mobile terminal is touched, the grouped string corresponding to the touched character key button is In the displaying step, when the character key button is dragged in the touch state, the plurality of characters included in the character string is dragged in conjunction, and among the plurality of characters included in the character string, the character dragged just before the end point of the touch Outputting the screen.

When the special key button is touched, a selection bar is generated on the screen, and when a user drags the selection bar while touching the selection bar, a plurality of special character key buttons corresponding to the next page may appear.

The mobile terminal further includes a mode switch key button. When the mode switch key button is touched, a jog button for selecting a Korean mode, an English uppercase mode, an English lowercase mode, and a numeric mode is generated. It can be switched to the touched mode.

The grouped string may be generated at one end of the character key button, and a generation position of the grouped string may be selected.

The grouped strings may be generated at the bottom of the touched character key button.

At least one of the character key buttons may include a special character.

When the drag direction deviates from the dragging process, the output of the character may be cancelled.

According to another embodiment of the present invention, in the method for inputting a character in a mobile communication terminal, when a consonant key button included in the mobile communication terminal is touched, other key buttons except the touched consonant key button are changed to a vowel key button. If the consonant key button is dragged in the touched state, the vowel key button located at the dragged point is converted into a selectable state, and the neutral and the touch corresponding to the vowel key button touched immediately before the touch end point. And outputting a letter combined with a consonant corresponding to a consonant key button on a screen.

The vowel key button is converted into a consonant key button when the letter combining the initial and the neutral is output on the screen, and when the consonant key button is touched, a finality corresponding to the touched consonant key button is applied to the letter. Combined and output to the screen may be further included.

As described above, according to the present invention, in the character input method of the mobile communication terminal, a desired character can be conveniently selected by dragging while the user touches it, and the number of key button touches required for character completion can be reduced.

In addition, according to the present invention, even when a complex vowel is input, the vowel can be directly selected by dragging, so that a complex vowel can be conveniently inputted without special learning about a vowel input pattern such as a stroke combination.

In addition, according to the present invention, since a touch and drag method is used, a character may be input using only one finger and the movement of the finger may be minimized, thereby minimizing fatigue during character input.

Also, by inserting frequently used special characters into the character key button, the user can conveniently select special characters without switching to the special character mode.

) Key button and delete (←) key button.

First, the special key button is a key button for selecting a special character such as a special symbol or an emoticon. 5A to 5C are views for explaining a process of selecting a special character by using a special key button.

When the user touches the special key button in the state as shown in FIG. 3, the input area 153 is switched from the normal character mode to the special character mode. That is, as shown in FIG. 5A, a selection bar is displayed at the lower end of the output area 151, and the special area or emoticon of various forms is displayed in the input area 153. As shown in FIG. 5A, when the user touches the special symbol "^", the selected special symbol "^" is displayed in the output area 151.

When the user drags the selection bar to the right while touching the selection bar, the special characters of the next page are displayed in the input area 153 as shown in FIG. 5B. On the contrary, when the user touches the selection bar and drags it to the left, the special area of the previous page is displayed in the input area 153 as shown in FIG. 5A. After the user inputs the special character, when the user touches the special key button, the input area 153 is switched from the special character mode to the normal character mode as shown in FIG. 5C.

Next, the mode key button is a key button for selecting the Hangul mode, the English uppercase mode, the English lowercase mode, the number mode among the normal text mode. 6A to 6C are diagrams for describing a process of selecting one of the general text modes by using a mode key button.

When the user touches the mode key button while composing a message, a four-way jog button for selecting Korean, English uppercase letters, English lowercase letters, and numbers is generated in a popup form as shown in FIG. 6A. In other words, the 4-way jog button is indicated by arrows indicating up, down, left and right, the up arrow selects the Hangul mode, the down arrow selects the number mode, the left arrow selects the English uppercase mode, and the right arrow selects the English lowercase mode. This is a key button to do this.

Therefore, if the user drags upward in the state of touching the mode key button, it is converted into Korean mode as shown in FIG. 3, and if the user drags downward in the state of touching the mode key button, the mode is converted to numeric mode as shown in FIG. do. In addition, when the user touches the mode key button and drags in the right direction, the mode is converted to the lowercase English mode as shown in FIG. 6C. In addition, although not shown, if the user touches the mode key button and drags to the left, it is converted to the uppercase English mode.

The Hangul input method in the state converted to the Hangul mode has been described in detail with reference to FIG. 3, and the English case input method is the same as the Korean input method. That is, in the case of the English lowercase mode as shown in FIG. 6C, when a user touches one of the key buttons included in the input area 153, the touched key button is displayed among the character group layers shown in Table 3 below. The character group layers are displayed in a line in the selection area 155.

That is, when the user drags upward or downward while touching the key button, the user may select a desired lowercase English letter among the character group layers shown in the selection area 155.

As described above, according to the embodiment of the present invention, by using a touch and drag method, the number of key button touches required for character completion is increased compared to the touch and touch character input method currently used. Decreases.

For convenience of explanation, a case of inputting the letter "윷" will be described with an example.

First, according to the 'Cheonjiin' input method using the catch combination method described in Figure 1a, ① consonant 'ㅇ' key button touch, ② vowel 'ㅡ' key button touch, ③ capture '·' key button twice in a row, ④ In order to input the consonant 'vo', touch the 'j' key button twice. Therefore, in order to enter the letter "윷", all six key buttons must be touched.

In addition, according to the 'Naratgle 2000' input method described in Figure 1b, ① touch the consonant 'o' key button, ② touch the 'ㅗ, TT' key button 2 times to input the vowel 'ㅠ' and then touch the '*' capture key button ( ㅗ → TT → ㅠ), ③ Touch 'ㅅ' key button to input consonant 'ㅊ' and then touch '*' capture key button twice (ㅅ → ㅈ → ㅊ). Therefore, in order to enter the letter "모두", all seven key buttons must be touched.

According to another touch and touch character input currently being used, ① touch the consonant 'ㅇ' key button to input the letter "윷", ② touch the 'TT' key button 2 times to input the vowel 'ㅠ' (TT → ㅠ), ③ To input consonant 'ㅊ', touch the 'ㅈ' key button twice. Therefore, all five key buttons must be touched to enter the letter "윷".

However, according to an embodiment of the present invention, in order to input the letter "윷" ① consonant 'ㅇ' key button touch, ② vowel 'TT, ㅠ' key button in the state of touching the drag 'vo' selection, ③ consonant Touch the 'ㅈ, ㅋ' key button and drag to go through the process of selecting the consonant. Therefore, in order to input the letter "모두", all three key buttons are touched. Therefore, the number of key button touches required for character completion is reduced by at least two times compared to the touch and touch character input method described above. In addition, while the prior art has a ambiguity to touch a number of times by mapping a number of characters to one key button, according to an embodiment of the present invention it is possible to select a character to be input through a single touch to input characters more accurately Can be.

In addition, according to an exemplary embodiment of the present invention, even when a complex vowel such as 'ㅞ', 'ㅙ', 'ㅒ', etc. is inputted, the vowel can be directly selected by dragging, so that the vowel input pattern such as a combination of combinations is specifically learned. You can conveniently enter complex vowels without having to.

In addition, according to an embodiment of the present invention, since a touch and drag method is used, a character can be input using only one finger and the movement of the finger can be minimized, thereby minimizing fatigue during character input. have. In particular, the arrangement of the selection area 155 can be freely changed from side to side, so that the user can conveniently input characters regardless of whether they are left-handed or right-handed. That is, according to FIG. 3, the selection area 155 is disposed on the right side so that a user who is left-handed may conveniently select a desired character without covering the selection area 155 with his left hand.

FIG. 7 is another diagram illustrating a text input screen displayed on a display unit of the mobile communication terminal of FIG. 3. According to FIG. 7, the selection area is disposed on the left side so that a user who is right-handed can conveniently select a desired character without covering the selection area with his right hand.

In addition, the function area 157 includes a special key button, and when the user touches the special key button during character input, the function area 157 is switched to the special character mode. Therefore, in order to use a special character such as a special symbol or an emoticon when inputting a general character, there is no need to search for a separate option or press a mode switch key button several times. Also, by inserting frequently used special characters such as question mark (?) Or period (.) Into the character key button, the user can conveniently select even without switching to the special character mode.

In addition, by using a four-way jog button that selects Korean, English uppercase letters, English lowercase letters, and numbers when the character mode is converted, the user can switch to the desired character mode with a single drag after touching the four-way jog button. In addition, according to an embodiment of the present invention, when the character is selected by dragging, if the finger or the stylus pen is deflected from side to side in the dragging process, the character input is canceled so that the character can be accurately input. In addition, according to an embodiment of the present invention, the character group layer further includes an X mark indicating cancellation in the bottom, so that when a user accidentally touches a key button by mistake, the key button input is canceled during dragging. Accordingly, in the case of FIG. 3, the character group layer displayed in the selection area 155 may include “ㅗ, ㅛ, ㅘ, ㅚ, ㅙ, X”.
