Abstract
Official abstract text for this publication.
Provided are a character input apparatus and method based on handwriting. The character input apparatus based on handwriting includes an image obtaining unit configured to obtain an image of a motion of a hand moving in a space, a pattern storage unit configured to store various types of character input pattern information required for inputting characters, a pattern recognizing unit configured to recognize a character input pattern from the image of a motion of a hand obtained by the image obtaining unit, compare the recognized character input pattern with the character input pattern information stored in the pattern storage unit, and output a character matched to the same pattern, and an input character display unit configured to display the character output from the pattern recognizing unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A character input apparatus based on handwriting, the character input apparatus comprising: an image obtaining unit configured to obtain an image of a motion of a hand moving in a space; a pattern storage unit configured to store various types of character input pattern information required for inputting characters; a pattern recognizing unit configured to recognize a character input pattern from the image of a motion of a hand obtained by the image obtaining unit, compare the recognized character input pattern with the character input pattern information stored in the pattern storage unit, and output a character matched to the same pattern; and an input character display unit configured to display the character output from the pattern recognizing unit. 2 . The character input apparatus of claim 1 , wherein when the recognized pattern corresponds to a consonant and repeated twice within a predetermined period of time, the pattern recognizing unit determines that the pattern corresponds to a pair consonant, and outputs a corresponding character. 3 . The character input apparatus of claim 1 , wherein when the recognized pattern is a vowel and another vowel continuously follows, the pattern recognizing unit determines that the pattern corresponds to a derivative vowel, combines the two successive vowels, and outputs a combined vowel. 4 . A character input method based on handwriting, the character input method comprising: storing various types of character input pattern information required for inputting characters; obtaining an image of a motion of a hand moving in a space; recognizing a character input pattern from the obtained image of a motion of a hand, comparing the recognized character input pattern with the stored character input pattern information, and outputting a character matched to the same pattern; and displaying the output character. 5 . The character input method of claim 4 , wherein, in the outputting of a character, when the recognized pattern corresponds to a consonant and repeated twice within a predetermined period of time, it is determined that the pattern corresponds to a pair consonant, and a corresponding character is output. 6 . The character input method of claim 4 , wherein, in the outputting of a character, when the recognized pattern is a vowel and another vowel continuously follows, it is determined that the pattern corresponds to a derivative vowel, and the two successive vowels are combined to be output.
