Device and method for controlling operation in terminal

The present invention relates to a device and a method for controlling operation in a terminal and, more specifically, to device and a method for controlling operation in a terminal, which are capable of controlling a touch operation generated when a user holds the terminal. To achieve the above purpose, the device for controlling operation in a terminal includes: a holding sensor unit which outputs a holding detection signal when a user holds a terminal; a touchscreen unit which includes a touch-inactive area for recognizing a touch signal as a holding action, when the touch signal is detected while detecting the holding detection signal; and a control unit which sets the touch-inactive area to the touchscreen unit and recognizes the touch signal generated in the touch-inactive area as a holding action, when the touch signal is detected while detecting the holding detection signal.
