METHOD AND APPARATUS FOR INPUTTING CHARACTER USING TOUCH INPUT
First Claim
1. An apparatus for inputting a character, the apparatus comprising:
- a touch input unit configured to sense a generation and a contact point of a touch;
a memory configured to store mapping information regarding a displacement and a character according to movement of the generated touch;
a controller configured to extract and output a character corresponding to a displacement of a sensed touch while the touch maintains upon sensing the touch; and
a display unit configured to display the output character.

Abstract
An apparatus and a method for inputting a character are provided. The apparatus for inputting a character includes a touch input unit configured to sense a generation and a contact point of a touch. The apparatus also includes a memory configured to store mapping information regarding a displacement and a character according to movement of the generated touch. The apparatus further includes a controller configured to extract and output a character corresponding to a displacement of a sensed touch while the touch maintains upon sensing the touch. The apparatus also includes a display unit configured to display the output character. The method and apparatus for inputting a character may increase character input speed, and provide an environment similar to a keyboard of a PC, for example, a key arrangement of a QWERTY type to improve convenience for a user.
