1. A touch coordinate predicting method of a mobile terminal, the method comprising:

  • detecting a consecutive touch movement on an application screen;

    displaying a touch output in response to the detected touch movement;

    determining a type of an application being currently displayed on the application screen, the type of the application being determined by an extent of a direction change of the touch movement;

    retrieving, from a memory, a ratio of gain values of a speed component and an acceleration component corresponding to the determined type of the application;

    differently amplifying the speed component and the acceleration component of the touch movement with different amplification ratios according to the retrieved ratio of gain values;

    calculating a touch coordinate predictive value, by adding the amplified speed component and the amplified acceleration component, to a current touch coordinate of the touch output; and

    displaying the calculated touch coordinate predictive value and the current touch coordinate of the touch output.
