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.
Claims5
A character input apparatus comprising:
- at least one memory configured to store character input pattern information indicating at least one character input pattern required for inputting characters;
- at least one processor configured to generate an image capturing a motion of a hand moving in a space, recognize a character input pattern from the image, determine an input character based on the recognized character input pattern and the character input pattern information, and control a display of the character input apparatus to display the input character
- wherein, when a character input pattern corresponding to a consonant is recognized twice within a predetermined period of time, the at least one processor determines the input character to be a pair consonant.
A character input method performed by a character input apparatus, the method comprising:
- generating an image capturing a motion of a hand moving in a space;
- recognizing a character input pattern from the generated image:,
- determining an input character based on the recognized character input pattern and character input pattern information indicating at least one character input pattern required for inputting characters;
- and
- controlling a display of the character input apparatus to display the input character,
- wherein the determining comprises, when a character input pattern corresponding to a consonant is recognized twice within a predetermined period of time, determining the input character to be a pair consonant.
