The present invention relates to a character input apparatus and method for a portable terminal, and more particularly, to an apparatus and method for simplifying a character input process in order to shorten the character input time of a portable terminal having a touch screen.

In recent years, as the portable terminal is gradually thinner and smaller, its use is rapidly spreading. Accordingly, service providers (terminal manufacturers) of the portable terminal are competitively developing terminals having more convenient functions to secure a large number of users.

For example, a touch screen type portable terminal for inputting data using a user's hand or a stylus pen has been developed so that text or lines can be easily drawn on the portable terminal using the stylus pen.

Currently, the portable terminal can receive data by selecting a specific menu displayed on the display unit or writing a character directly through the stylus pen.

However, the portable terminal may perform character input by touching a keyboard-type input screen output on the display unit, but a general keyboard-type input screen is a QWERTY-based input screen, and the distance between the vowel and the consonant is separated. There is an inconvenience.

That is, when the character data is input through the input screen as described above, there is a problem in that the character data input time is long because the pointing adjustment is difficult.

In addition, since the size of the keyboard-type input screen is limited according to the mechanical characteristics of the miniaturized portable terminal, a pointing operation required for text data input is inconvenient.

Accordingly, there is a need for an apparatus and method for enabling fast text data input in a portable terminal having a touch screen as described above.

Another object of the present invention is to provide an apparatus and method for providing vowel characters that can be combined when text data is input in a portable terminal capable of touch input.

According to a first aspect of the present invention for achieving the above objects, a text data input device of a portable terminal having a touch sensor detects text data input by a user and performs a touch corresponding to the input. A coordinate checking unit measuring a position of the input touch using a sensor and touch information input to the touch sensor and providing the measured position to a controller, and detecting a touch by a user while performing a touch input mode. And a controller configured to check the input text data of the position where the touch input is generated from the coordinate checking unit and the text data corresponding to the touch movement direction to combine the text data.

According to a second aspect of the present invention for achieving the above object, the character data input method of a portable terminal having a touch sensor, when detecting the touch by the user in the touch input mode, the coordinate of the position where the touch is detected And acquiring the coordinates and combining the input text of the position where the touch is detected and the text data corresponding to the touch movement direction when the touch movement occurs after the coordinate acquisition.

As described above, by using the character input device and method according to the present invention, the character input pointing process is reduced compared to the character data input process of the existing portable terminal, thereby reducing the character input time.

For example, when performing a process and control for voice call and data communication, and in accordance with the present invention in addition to the normal function, when detecting the touch by the user during the touch input mode, the coordinate checking unit 102 Instructs a user to obtain coordinates of a location where the user's touch is detected.

Thereafter, the controller 100 checks the text data existing at the location where the touch is generated by using the coordinates of the position where the touch is detected by the coordinate checking unit 102 and outputs it to the display unit 110. Do it.

Then, when detecting the touch movement by the user, the control unit 100 checks the character data (eg, vowel, vowel + consonant) corresponding to the detected direction to initially output the character and the touch movement direction. Process to combine and output the corresponding character data.

In addition, the controller 100 checks the location where the touch has occurred and processes the text data existing in the checked position and the combined text data that can be combined with the text data to the display unit 110.

Here, the combination text data may include a stroke add button (·) as characters (collections) that can be combined with text data initially input from a user.

Thereafter, the controller 100 detects a touch movement by a user and processes the text data and the combined text data to be combined and output to the display unit 110 in a method corresponding to the detected touch movement order.

The coordinate checking unit 102 measures the coordinates of the position where the user's touch is generated by the instruction of the controller 100 and provides the coordinates to the controller 100.

The touch sensor 104 is a sensor that detects a user's input, such as a touch screen and a touch pad, detects the user's touch input, and provides the detected touch input information to the controller 100.

In the following description, FIG. 3 is a diagram illustrating a screen configuration of a portable terminal combining text data according to the touch movement direction.

Referring to FIG. 2, the control unit 100 of the portable terminal first performs a touch input mode in step 201, and then proceeds to step 203 to check whether a touch input by a user is detected. Here, the touch input mode refers to a mode that enables data input including text input using an input tool such as a stylus pen as shown in FIG. 3.

If the touch input by the user is not detected, the controller 100 performs the process of step 201 again.

On the other hand, when detecting the touch input by the user, the control unit 100 proceeds to step 205 instructs the coordinate checking unit 102 to obtain the coordinates of the position where the touch input is detected.

Here, the coordinate checking unit 102 instructed by the controller 100 calculates the distance of the position where the touch is detected based on a predetermined position and measures the coordinates of the position where the touch input is detected. Provided to the controller 100.

In operation 207, the control unit 100 checks the text data existing at the location where the touch is detected using the location information provided from the coordinate checking unit 102, and then displays the checked text data in the display unit ( Output to 110).

In operation 209, the controller 100 determines whether the user senses a touch movement. Here, the touch movement refers to a situation where the user of the portable terminal changes the position of the touched point while maintaining the touch of the touch sensor 104.

If the touch movement is not detected, the controller 100 performs the process of step 209 again.

On the other hand, when detecting the touch movement, the control unit 100 proceeds to step 211 to instruct the coordinate checking unit 102 to obtain the coordinates of the position where the touch movement is detected.

The coordinate checking unit 102 which is instructed by the control unit 100 obtains the coordinates of the position where the touch movement is detected, and provides the coordinates to the control unit 100.

That is, the controller 100 may check the moving direction (eg, up, down, left, right, etc.) of the touch by comparing the coordinates provided from the first coordinate checking unit 102 with the coordinates for the last point.

When determining the touch movement direction, the control unit 100 proceeds to step 215 to check the vowel character corresponding to the checked touch movement direction, and proceeds to step 217 to check whether the touch maintenance end by the user is detected.

Here, the vowel character corresponding to the touch movement direction is a single vowel character (for example, ㅏ, ㅓ, ㅗ, TT) except for a compound vowel (for example, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, etc.). Say).

That is, the controller 100 detects a vowel character "ㅗ" when detecting a touch movement in the upper direction and a vowel character "TT" when detecting a touch movement in the lower direction, and performs a touch movement in the left direction. When detecting, the vowel character "ㅓ" is detected, and when detecting a touch movement in the right direction, the vowel character "ㅏ" can be checked.

3 (b) is a screen outputting the text data of "ho" in the same manner as described above when the user of the portable terminal first touches the text data of "ㅎ", and then confirm that the touch movement in the upward direction The portable terminal may output text data of "ho" to the display unit 110, and the portable terminal may output text data as shown in FIGS. 3 (c) and 3 (d) according to the touch movement direction. can do.

In addition, the above method is not only a combination of single vowel characters (e.g., ㅏ, ㅓ, ㅗ, TT) but also a combination of fold vowels (e.g., ㅕ, ㅑ, ㅛ, ㅠ) through repeated touch movements and input of a specific key. The combination of the complex vowels (eg, ㅐ, ㅒ, ㅔ, ㅖ, ㅘ, ㅙ, ㅚ, ㅝ, etc.) may be input through a key input button provided in the touch input mode.

If the end of touch holding is not detected, the controller 100 performs the process of step 209 again.

On the other hand, when detecting the end of the touch holding, the control unit 100 proceeds to step 219 and combines the vowel character confirmed in step 215 and the selected text data to process the output to the display unit 110.

That is, the controller 100 may check the movement direction (eg, up, down, left, right) of the touch by comparing the coordinates provided from the first coordinate checking unit 102 with the coordinates for the last point.

When checking the touch movement direction, the control unit 100 proceeds to step 415 to check the vowel character corresponding to the checked touch movement direction, and proceeds to step 417 to check whether the touch maintenance end by the user is detected.

Here, the vowel character corresponding to the touch movement direction refers to a combination of vowels (eg, "-", "|") and a stroke addition button (.) That can be combined when text data is input.

That is, the controller 100 may combine characters such as "ㅗ", "TT", "ㅢ", "ㅏ", and "ㅓ" by combining the combination vowel and the stroke add button.

For example, as shown in FIG. 5B, when the user of the portable terminal first touches the text data of "ㅎ", the portable terminal outputs the touched text data and the combined text data. When the mobile device detects a touch movement via the text data of "ㅣ" and "·" using the text data of "ㅎ" as a starting point (505), the portable terminal displays the text "ha" as shown in FIG.
