  • Method for operating touch input device and portable terminal using the same
    Patent number: 8169413
    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.

  • METHOD AND APPARATUS FOR SUPPORTING INPUT FUNCTION WHEN TOUCH INTERFACE OF A TOUCHSCREEN-BASED DEVICE MALFUNCTIONS
    Publication number: 20110291974
    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.
