A method of controlling a touch input of a terminal is provided. The method includes determining, when a touch input is sensed, a touch position, and setting a partial area of a touch panel including the determined touch position as an effective touch area of the touch panel. The method may further include determining, when the touch input is sensed, whether the touch input is a pen touch input, and sensing the touch input through a touch panel for sensing a user touch and an Electro Magnetic Resonance (EMR) panel for sensing the pen touch input, wherein the touch position is determined when the touch input is a pen touch sensed through the EMR panel.
