ABSTRACT:
A hand-writing input device comprises: an input surface, a guidance device provided on the input surface along a predetermined track to guide a finger or pen along the track; a plurality of switch elements provided at particular positions on the track. When a particular character is inputted, the triggered switch element outputs the corresponding signal, and the combinations of the signals outputted by the switch elements correspond to the inputted characters. Since hand-writing input is performed by guiding a finger or pen along a predetermined track, only few switch elements are needed, thereby simplifying hand-writing recognition, reducing software requirements and increasing recognition accuracy.
