Character recognition apparatus |
摘要 |
An apparatus for recognizing a character (including an alpha-numeric character, mark or other character) written using a stylus applied to a tablet which stylus and tablet include an arrangement for providing an indication of position of the stylus with respect to a surface of the tablet. The character recognition apparatus determines the length and gradient (slope) of line segments of strokes drawn by a user which strokes combine to form characters. After determining length and gradient of a line segment, there is assigned to the line segment a distinctive code. A particular character is determined by examining the order of codes which define particular combinations of strokes. Recognition of characters is carried out in substantially real time.
