Abstract: An apparatus for driving a touchpad of a portable terminal including a second control unit controlling the touchpad in an active mode is provided. The apparatus includes a sensor unit for generating interrupt signals when pressure on the touchpad is sensed, a first control unit for outputting activating signals to activate the second control unit when the interrupt signals are input and a switching unit for transmitting the interrupt signals generated from the sensor unit to the first control unit when the second control unit is in an inactive mode. Accordingly, even though the multimedia processor embedded in the portable terminal is in an inactive mode, the multimedia processor is activated when a user presses the touchpad, thereby making it possible to process signals input by touching the touchpad, particularly, to keep the user interface. Furthermore, the multimedia processor embedded in the portable terminal can reduce the consumption of battery power required to maintain the user interface, as compared with multimedia processors maintaining operating in a conventional polling method.

Abstract: Provided are an electronic apparatus for determining validity of touch key input and a method and apparatus for determining validity of touch key input for the electronic apparatus. The method includes determining whether a touch key is input to perform a preset function, determining whether a dummy key used to determine validity of input of the touch key is input, if determining that the touch key is input, and determining validity of input of the touch key based on whether the dummy key is input. According to the present invention, by determining whether touch key input is intended by a user, it is possible to prevent a function undesired by the user from being performed.
