Method of displaying information by using touch input in mobile terminal

Abstract

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 the 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.

What is claimed is: 
     
         1 . A method of displaying information in a mobile terminal, the method comprising:
 determining whether a touch input is generated by a touch screen;   determining, if a touch input is generated by a touch screen, whether a touch area moves;   calculating, if the touch area moves, 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.   
     
     
         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 at least one 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 a touch input is generated, mode indication icons of individual movement directions. 
     
     
         10 . The method of  claim 9 , wherein the mode indication icons disappear when a displacement value is displayed. 
     
     
         11 . The method of  claim 1 , further comprising:
 determining, after displaying at least one of the displacement value generated by executing the function of the current mode and the current mode icon indicating the current mode, 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 . A method of displaying information in a mobile terminal, the method comprising:
 determining whether a mode is selected from a touch screen;   setting, if the mode is selected from a touch screen, the selected mode as the current mode, and determining whether a touch input is generated by the touch screen;   extracting, if the touch input is generated by the touch screen, an outermost coordinate from the coordinates of the touch area; and   displaying a current mode icon maintaining a distance from the extracted outermost coordinate.   
     
     
         13 . The method of  claim 12 , further comprising:
 determining, after displaying the current mode icon, whether the touch area moves;   extracting, if the touch area moves, the coordinates of the touch area; and   executing a function of the current mode corresponding to the extracted coordinates of the touch area.   
     
     
         14 . The method of  claim 13 , wherein the executing of the function of the current mode comprises displaying a displacement value generated by executing a function of the current mode. 
     
     
         15 . The method of  claim 14 , wherein the displacement value is displayed in a numeral form. 
     
     
         16 . The method of  claim 15 , wherein the displacement value is displayed in a bar form. 
     
     
         17 . The method of  claim 12 , wherein the displaying of the current mode icon comprises displaying, adjacent to the current mode icon, a displacement value generated by executing a function of the current mode. 
     
     
         18 . The method of  claim 12 , wherein the outermost coordinate comprises at lease one of the uppermost coordinate, the leftmost coordinate, and the rightmost coordinate of the touch area. 
     
     
         19 . The method of  claim 12 , wherein the determining of whether the mode is selected comprises:
 displaying a plurality of mode indication icons; and   identifying whether a mode indication icon is selected from the displayed mode indication icons.   
     
     
         20 . The method of  claim 12 , further comprising:
 determining, after displaying 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.
