Method and apparatus for handling touch input in a mobile terminal

An apparatus for controlling a mobile terminal comprising a touch screen, the apparatus comprising:

• a display comprising a touch screen;
• a controller configured to:
• display a screen on the touch screen;
• detect a plurality of touch inputs;
• determine an actual coordinate value of a first touch input;
• obtain a predicted coordinate value for the determined actual coordinate value of the first touch input;
• obtain a smoothed coordinate value by performing a smoothing operation on the predicted coordinate value, the smoothing operation including calculating the smoothed coordinate value based on an average value of the predicted coordinate value of the first touch input and predicted coordinate values of a predetermined number of touch inputs among the plurality of touch inputs, wherein the predetermined touch inputs are obtained before the first touch input;
• determine that the first touch input has occurred at the obtained smoothed coordinate value;
• and
• scroll the screen displayed on the touch screen according to the smoothed coordinate value;
• and
• a memory configured to store the determined actual coordinate value, the predicted coordinate value for the determined actual coordinate value, and the obtained smoothed coordinate value for the obtained predicted coordinate value.
