Abstract: A method for controlling rotation of a screen according to a user request regardless of an orientation state of the terminal is provided. The terminal for supporting screen rotation control, includes a sensor unit including a sensor for confirming a horizontal state of the terminal and a sensor for collecting angular velocity information of the terminal, a controller for confirming the horizontal state of the terminal based on sensing information of the sensor unit, and for confirming a rotated state or a rotation change state of the terminal in a corresponding horizontal state when the terminal is arranged in the horizontal state, and a display unit for outputting a screen having a different output direction according to the rotated state or the rotation change state of the terminal.

Abstract: An input apparatus of a portable terminal and an input method for compensating an input from a pen to increase the accuracy of the pen are provided. The input apparatus includes a touch panel configured to generate an input signal according to a pen touch, a memory configured to store at least one lookup table in which data for compensating an error of a pen input according to a user's pen usage characteristic is stored, a controller configured to detect an input coordinate of the pen touch on the touch panel and configured to extract compensation data from the lookup table corresponding to the input coordinate to compensate the error of the pen input, and a display unit configured to display a compensated pen input signal.
