Abstract: An apparatus and a method for inputting a character using user's motion is provided. When a user's hand makes a motion, a character input pattern is recognized from the motion, a character to be input is determined by comparing the recognized character input pattern with character input pattern information which predefines various character input patterns and corresponding characters, and the determined character is displayed.
