发明名称 Electromagnetic Induction Handwriting System and Coordinate Determining Method Thereof
摘要 The present invention discloses an electromagnetic induction handwriting system and its single side coordinate determining method for determining a coordinate of a stylus on a handwriting apparatus. The coordinate is computed by a first voltage, a second voltage, and a third voltage, where the first voltage equals the maximum detection voltage, the second voltage and the third voltage are obtained from two antennas, and both of the two antennas are arranged at the same side of the antenna that induces the maximum detection voltage.
