Abstract
The present invention relates to electronic, electric, and communication devices requiring a user to input characters, more particularly to, a character input apparatus and method to receive characters using shapes of characters. The character input apparatus according to the present invention recognizes the characters using selection order or selection combination corresponding to the character shape inputted from touch sensors or buttons by the user to input a character and displays the recognized character on a screen.
Claims21
A character input apparatus comprising:
- a sensor means for sensing a hand's touch of a user who writes characters to input the characters;
- a character recognition and control means for recognizing the inputted character according to a touch order of the sensor means;
- a storage means for storing data of the recognized character;
- and
- a display means for displaying the stored data of the character recognized by the character recognition and control means on a screen.
A character input apparatus comprising:
- a sensor means for sensing a hand's touch of a user who touches a plurality of touch sensors thereof arranged and spaced from each other with a predetermined distance;
- a character recognition and control means for comparing combination of the touched sensors of the sensor means with stored character correspondence patterns and recognizing a character;
- a memory for storing a character pattern corresponding to the hand's touch of the user;
- and
- a display means for displaying the character recognized by the character recognition and control means on a screen.
A character input apparatus comprising:
- a character input means having a plurality of key buttons for allows a user to input character by selecting the key buttons corresponding to character shape;
- a character recognition and control means for recognizing the inputted character according to order of the selected key buttons;
- a storage means for storing data of the recognized character;
- and
- a display means for displaying, the stored data of the character recognized by the character recognition and control means on a screen.
A character input apparatus comprising:
- a character input means for allows a user to input character by selecting buttons corresponding to character shape using a predetermined number of buttons on a key pad;
- a character recognition and control means for comparing combination of the selected buttons with stored character correspondence patterns and recognizing the inputted character;
- a memory for storing patterns of buttons corresponding to the inputted characters;
- and
- a display means for displaying the stored data of the character recognized by the character recognition and control means on a screen.
A character input method comprising the steps of:
- (a) when a user touches a plurality of sensors arranged and spaced from each other with a predetermined distance, sensing a touch order of the sensors corresponding to a character which the user writes by hand;
- (b) recognizing a character corresponding to the sensed touch order;
- and
- (c) storing and displaying data of the recognized character.
A character input method comprising the steps of:
- (a) sensing a user's hand touch to input characters by a plurality of sensors arranged and spaced from each other with a predetermined distance;
- (b) comparing combination of the sensors corresponding to hand's touch with stored character correspondence patterns;
- (c) recognizing a character corresponding to the combination of the sensors from character correspondence patterns according to a result of comparison;
- and
- (d) displaying data of the recognized character on a screen.
A character input method comprising the steps of:
- (a) selecting buttons according to character shape using a predetermined number of buttons on a keypad;
- (b) recognizing and storing an inputted character according to order of the selected buttons;
- and
- (c) displaying data of the recognized and stored character on a screen.
A character input method comprising the steps of:
- (a) selecting buttons according to shape of a character to inputted using a predetermined number of buttons on a keypad;
- (b) comparing combination of the selected buttons with character correspondence patterns stored in a memory, finding a character corresponding to one of the character correspondence patterns and recognizing the inputted character;
- and
- (c) displaying the recognized character on a screen.
