PORTABLE TERMINAL AND CHARACTER INPUT METHOD FOR SAME
First Claim
1. A terminal comprising:
- a display unit configured to display information;
a touch input device formed on the display unit;
a memory configured to store character information representing a character corresponding to a touch shape in a predetermined region of the display unit; and
a control unit configured to receive input of the touch input device and process the received input, and display a character corresponding to touch information on the display unit by comparing the touch information output from the touch input device in a character input mode and the character information.

Abstract
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.

7. A terminal, comprising:
-
a display unit configured to display information; a touch input device formed on the display unit; and a control unit configured to receive input of the touch input device and process the received input, display the predetermined number of regions on the display unit in a character input mode, and compare touch information output from the touch input device with character information serving as a reference when a user touches the region to display a character corresponding to the touch information on the display unit, wherein a touch shape of each character of the character information corresponds to an original shape of a character.
