Method of displaying information by using touch input in mobile terminal
A method of displaying information in a mobile terminal having a touch screen is provided. The method includes determining whether a touch input is generated by a touch screen, determining whether a touch area moves, calculating a movement direction of the touch area by extracting a value of the touch area movement, determining a current mode according to the calculated movement direction of the touch area, executing a function of the current mode corresponding to the extracted value of the touch area movement, and displaying, while executing the function of the current mode, at least one of a displacement value generated by executing the function of the current mode and a current mode icon indicating the current mode. Accordingly, when displaying information according to a touch input, changes of information may be displayed distinctively, and thereby user convenience may be improved.
1. A method of displaying information in a mobile terminal, the method comprising:
displaying a screen image in response to a function executed by a mobile terminal; and
determining whether a touch input is generated by a touch screen;
while the touch input is generated:
determining whether a touch area moves;
calculating, when the touch area is determined to move, a movement direction of the touch area by extracting a value of the touch area movement;
determining a current mode according to the calculated movement direction of the touch area;
executing, on the displayed screen image, a function of the current mode corresponding to the extracted value of the touch area movement, and changing the displayed screen image in accordance with the executed function; and
displaying, while executing the function of the current mode, a displacement value representing an extent of the function executed according to the extracted value and a current mode icon indicating the current mode on the changing screen image.
2. The method of claim 1 , wherein the current mode is set to a first mode if the calculated movement direction is a vertical direction and to a second mode if the calculated movement direction is a horizontal direction.
3. The method of claim 1 , wherein the displacement value is displayed in a numeral form.
4. The method of claim 1 , wherein the displacement value is displayed in a bar form.
5. The method of claim 4 , wherein the bar form is disposed corresponding to the movement direction.
6. The method of claim 1 , wherein the displaying of the displacement value and the current mode icon comprises:
extracting an outermost coordinate from the coordinates of the touch area; and
displaying the current mode icon maintaining a distance from the extracted outermost coordinate.
7. The method of claim 6 , further comprising displaying the displacement value in a numeral form beside the current mode icon.
8. The method of claim 6 , wherein the outermost coordinate comprises at least one of the uppermost coordinate, the leftmost coordinate and the rightmost coordinate of the touch area.
9. The method of claim 1 , further comprising displaying, before determining whether the touch input is generated, mode indication icons of individual movement directions.
10. The method of claim 9 , wherein the mode indication icons disappear when the displacement value is displayed.
11. The method of claim 1 , further comprising:
determining, after the displaying of the displacement value and the current mode icon, whether the touch input generated by the touch screen is discontinued; and
erasing, if the touch input generated by the touch screen is discontinued, the current mode icon.
12. The method of claim 1 , wherein the displaying of the displacement value and the current mode icon comprises:
displaying the displacement value and the current mode icon along the touch area movement.
