Disclosed are a portable terminal and a character input method thereof. Touch information corresponding to input selected by a user from a touch device is received, and a control unit calculates a region in which the touch information starts, a region in which the touch information ends, and a region in which the touch information turns. Then, the control unit determines a character corresponding to the region in which the touch information starts, the region in which the touch information ends, and the region in which the touch information turns with reference to the memory. Further, the control unit determines whether there is a motion of turning an apex of the region in a predetermined direction, and when the motion of turning the apex of the region in the predetermined direction is input, the control unit changes a character input mode. Thus, a character may be accurately and simply input by inputting a character in a predetermined region displayed on a screen larger than an existing screen by using a touch device.
