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.

Abstract: A method and apparatus for supporting an input function to a touchscreen-based device when the touch interface malfunctions are provided. The input function supporting method includes detecting an input operation via a function key, determining, when the input operation is performed via the function key, an input manner of the input operation via the function key, changing, when the input manner of the input operation via the function key corresponds to a preset manner, a current mode to an emergency input mode, and processing a function, according to another input operation of the same or another function key, in the emergency input mode.

Abstract: A mobile commerce execution method and apparatus using a mobile device and an external mobile commerce module is provided. The method for executing mobile commerce includes detecting, at the mobile device, a connection of an external module, determining whether the external module is a mobile commerce module, activating a mobile commerce function by exchanging control signals with the mobile commerce module, and executing an operation according to a key input.

Abstract: An apparatus and method for registering a telephone number received by a mobile terminal as the latest number and enabling a new call connection to the latest number during or after a phone call are provided. The method of the call connection includes checking input information during a phone call between a calling party and a called party, identifying, if the input information is received, the input information and extracting a telephone number included in the input information, performing, if a call connection is requested after extracting the telephone number, a tripartite call connection to a mobile terminal corresponding to the extracted telephone number, and performing, if a phone call is terminated after extracting the telephone number, a call connection to a mobile terminal corresponding to the extracted telephone number.
