Hereinafter, with reference to Figure 2 will be described in detail the operation of the character input method using the touch screen according to a specific embodiment of the present invention.

2 is a flowchart illustrating a text input method using a touch screen according to a specific embodiment of the present invention.

As shown in FIG. 2, the present invention starts from the controller 10 receiving a text input command from a user (S100).

The text input command is preset according to the type of electronic device provided with the touch screen. In the case of the PDA, the text input command is an execution command of a function requiring text input such as a message writing command or a mail writing command.

Therefore, the start command may be made of an execution button input of the terminal body or an execution input on the touch screen unit 110.

In addition, the controller 10 causes the text box 400 to pop-up according to a text input command (S110).

In this case, the text box 400 displays the type character array 420 according to the drag direction, and pops up at a predetermined position on the touch screen 110. Here, the position of the text box 400 may be various positions depending on the design and configuration of the mobile device.

In addition, the controller 10 determines whether the first drag 500 is detected by the user (S120). Here, the first drag 500 refers to dragging in the up, down, left and right directions on the text box 400 from the first user.

Next, when the first drag is detected, the controller 10 displays the type letter array 420 according to the detected direction of the first drag 500 (S130).

The type character array 420 is displayed in the longitudinal or transverse direction with respect to the character box 400.

At this time, the control unit 10 detects the second drag 510 when the type character array 420 is an English array as a result of the determination of step 130, and determines the second drag 510 according to the direction of the second drag 510. Case is determined (S210, S212).

On the other hand, the control unit 10 detects the second drag 510 when the type character array 420 is a number array as a result of the determination of step 130, and displays the string according to the direction of the second drag 510. Convert to numbers or special characters (S220, S222).

If the type character array 420 is a Hangul / vowel array, the control unit 10 also detects a second drag (S230), and then moves toward the second drag 510. Scroll the character array accordingly (S232).

In this case, after performing step 232, the controller 10 determines whether to release the touch (S240).

As a result of the detection of step 240, when the touch release is detected, the controller 10 receives a character located on the text box 400.

The controller 10 detects the third drag 520 after performing the second and second steps 222 and 222, and scrolls the character array according to the direction of the third drag 520 (S310 and S312).

Here, if the third drag 520 is not detected from step 310, the controller 10 detects whether the touch is released (S400).

In addition, when it is determined that the touch release is not detected as the determination result of step 240, if the type character array 420 is a Hangul consonant array, the controller 10 detects the third drag 520. According to the direction of the three-drag 520, the characters located on the text box 400 is converted into a sound or double consonants (S320, S322).

In this case, if the third drag 520 is not detected as a result of the determination of step 320, the controller 10 performs step 240.

On the other hand, if the touch release is not detected as a result of the determination in step 240, if the type character array 420 is the Hangul vowel array, the control unit 10 detects the third drag 520 and the third drag. According to the direction (520), the characters located on the text box are converted into a pair of vowels (S330, S332).

If the third drag 520 is not detected as the determination result of step 330, the controller 10 performs step 240.

After performing step 332, the controller 10 determines whether the touch release is detected (S400).

Here, the controller 10 controls to move in two paths when the touch release is not detected in the operation 400.

That is, if the touch release is not detected as a result of the operation 400, the controller 10 determines that the type character array 420 determined according to the direction of the first drag 500 is an English character array and a numeric array. Control to perform step 310 (see dashed line in Figure 2). However, if the type character array 420 is the Hangul consonant array or Hangul vowel array, the device waits until the touch is released (see solid line in S400 of FIG. 2).

Subsequently, when the touch release is recognized as the determination result of step 400, the controller 10 receives the corresponding character located at the set position (S410). At this time, the input of the character refers to receiving the character located in the text box.

That is, in the specific embodiment of the present invention, the text box has been set as an example.

Next, the controller 10 combines the input characters and displays them on the touch screen unit 20 (S420). For example, the letter “L, E” may be combined by combining the letters 'ㅇ, ㅔ, ㄹ, ㅈ, l, ㅈ, ㅓ, ㄴ, ㅈ, ㅏ'. In addition, it is also possible to combine the letters 'Korea,' by combining the letters 'ㄷ, ㅐ, ㅎ, ㅏ, ㄴ, ㅁ, l, ㄴ, ㄱ, ㅜ, ㄱ'. Here, although the example is in Korean, English, numbers, special symbols, and other national characters may be combined into letters.

In addition, the controller 10 controls the scroll speed to be proportional to the drag length when the type character array 420 is scrolled. For example, if the drag length during scrolling is short, the controller 10 controls the scroll speed to be slow, and if the drag length is long, the controller 10 controls to speed the scroll speed.

In addition, the controller 10 controls to stop scrolling when the touch means 410 is positioned on the text box 400. In this case, one character of the character array is displayed on the text box 400.

That is, when the user inputs the first drag 500, one of the English character array, the numeric array, the Hangul consonant array, and the Hangul vowel array is displayed on the text box 400. In addition, when the user inputs the second drag 510, the English character sequence is distinguished from the upper and lower case letters. Also, special characters and numbers are distinguished in the array of numbers. Next, the Hangul consonants scroll in the Hangul consonant array, and the Hangul vowel scrolls in the Hangul vowel arrangement.

In addition, when the user makes the third drag 520, the English character scrolls in the English character array. In the array, the numbers scroll. Next, the consonant is converted to a consonant or a double consonant in the Hangul consonant array, and the vowel is converted into a double vowel in the Hangul vowel arrangement.

In the present embodiment, the case in which the type character array 420 is displayed in the horizontal direction is taken as an example. That is, when one Hangul consonant array or Hangul vowel array is set one above and one among the first drags, one English array or one numeric array is set in the left and right directions of the first drag, respectively.

However, unlike the present embodiment, when the type character array is displayed in the longitudinal direction, one or more English or numeric arrays are respectively set up and down in the first drag, and the left and right directions of the first drag are set. Each Hangul consonant array or Hangul vowel array may be set one by one.
