FIG. 15 illustrates an input process of '한글' among Hangul consonants, selecting 'a' from the indicators presented after determining the touch area as shown in (15a) to (15b), and a finger as shown in (15c). When you release and drag upward, 'ㄲ' is inputted. In addition, after the 'ㄲ' input, if you take your finger for a while to drag downward, it will be reduced back to 'A'. In this way, any Hangul consonant in Korean can be easily input.

16 illustrates a case change of English characters through a predetermined gesture.

After selecting 'b' from among the predetermined indicators as shown in (16a) to (16b) and then releasing the finger for a while as shown in (16c), the lowercase letter 'b' is converted to uppercase letter 'B'. Likewise, if you release your finger for a while and drag downward, the uppercase letter 'B' is converted to the lowercase letter 'b'.

FIG. 17 illustrates a state in which an indicator through a predetermined gesture is replaced with a next order indicator.

That is, the user can rotate the touched finger in the left or right direction in the touch area, thereby replacing the first and second indicators with next order indicators step by step.

For example, when the indicators of 'b, b, c, d' are presented, and the next order indicators are 'ㅁ, ㅂ, ㅅ, ㅇ', when the user rotates the touched finger in a predetermined direction, the rotation angle of the finger 'B, c, d, ㅁ', 'c, d, ㅁ, ㅂ', 'r, ㅁ, ㅂ, ㅅ', and 'ㅁ, ㅂ, ㅅ, ㅇ' It is manifested sequentially.

That is, the scrolling method deletes some indicators from the indicators presented to the user in the indicator presentation area, and presents an indicator that is replaced with the deleted indicator. As such, the user may easily rotate the finger on the touch screen to replace the components of the indicator step by step and sequentially.
