Abstract: 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.

Abstract: 본발명은전자펜을이용한필기인식시스템에관한것으로, 더욱상세하게는프로젝터로투사된스크린영역상에서전자펜을이용해판서하는경우상기전자펜에형성된압전센서에의해위치를판독하고필기를인식하여특정문자체로변환하고변환된내용을다시프로젝터로투사할수 있고, 상기인식된필기내용의문자체를자유롭게변경할수 있는전자펜을이용한필기인식시스템에관한것이다.
