Abstract:
A method for operating a touch input device and a portable terminal using the touch input device may prevent a malfunction of the touch input device due to an abrupt change of external temperature. The method for operating a touch input device measures a temperature, calculates a temperature difference value between temperatures measured at a current time point and a previous time point, and compensates a recognition threshold value used for detecting a touch event with a predefined compensation value based on the temperature difference value.
