WRITING DISCERNMENT SYSTEM USING ELECTRIC PEN

摘要

PURPOSE: A system for recognizing a note by using electronic pen is provided to automatically store content about note which lecture writes on a projector. CONSTITUTION: A piezoelectric sensor(110) of an electronic pen(10) converts a electric potential signal generated from a piezoelectric sensor during writing into a distance signal. A character conversion unit(230) of a projector reads the location of an electronic pen from the displacement signal. Based on note content, the letter conversion unit performs conversion to a letter. A letter output control unit(240) performs control operation to enable a converted letter to be projected on screen.
