<p>A real time input device for handwritten chinese characters comprises a matrix of mutually perpendicular and insulated row and column conductors and a pen-like object with a conducting head. When the pen head touches the plane of the matrix, rows and columns are connected. As a character is written the pen head is moved on the matrix and the coordinates thereof are changed accordingly. The stroke can be recognized by distinguishing the direction and the distance of the movement of coordinates. Recognition is carried out using a small amount of internal memory, only 16 binary digits for the internal code of each character, the possibility of using different sequences of strokes for some characters, no multi-character code for output. These are achieved because two transformations of the primary codes, and indexing pages by radical codes are employed. <IMAGE></p> |
