Abstract: A method for processing a multi-touch input for a mobile device having a touch screen of a resistive overlay type which is normally incapable of recognizing a multi-touch input. A first data based on a first touch is displayed and a second touch is detected while the first touch is maintained. An intermediate data unexpectedly occurring between the first and second touches is treated as invalid data and removed when one of the first and second touches is released. Then a second data based on the second touch is displayed. This method makes it possible to properly recognize a multi-touch input through software-based technique, while reducing unexpected input errors caused by a multi-touch input and thus permitting a user's quick input action.
