However, the change of the wiring method causes certain handwriting accuracy problems in a specific area (also called the offset area in this paper). In order to keep the handwriting accuracy of the offset area basically consistent with other areas, a method is needed to correct the deviation The positioning error of the shifted area

The invention discloses a coordinate correction method and device and an electromagnetic touch-control device, and belongs to the technical field of electromagnetic touch control. The coordinate correction method comprises the following steps of judging whether a hand-written track point is in the deviation area according to the coordinates of the hand-written track point, obtaining a compensation value in the transverse or longitudinal direction according to the transverse coordinate and the longitudinal coordinate of the hand-written track point if the hand-written track point is located at the deviation area, and correcting the coordinate, in the direction, of the hand-written track point according to the compensation value in the transverse or longitudinal direction. According to the coordinate correction method and device and the electromagnetic touch-control device, the compensation value in the transverse or longitudinal direction is obtained according to the transverse coordinate and the longitudinal coordinate of the hand-written track point, then the coordinate, in the corresponding direction, of the hand-written track point located in the deviation area is corrected according to the compensation value in the direction, and after correction, the deviation amount of the hand-written track point located in the deviation area is obviously improved.
Description
technical field [0001] The present invention relates to the field of electromagnetic touch technology, and more specifically, to a coordinate correction method and device, and an electromagnetic touch device. Background technique [0002] Electromagnetic handwriting input touch device (hereinafter referred to as: electromagnetic touch device) is a universal human-computer interaction device, just like keyboard, mouse and tablet. The electromagnetic touch device consists of an electromagnetic touch pen and an electromagnetic touch panel, wherein the electromagnetic touch panel includes two parts: an antenna board and a control board. The electromagnetic touch device has high positioning accuracy, can detect the pressure of the user's pen, can be connected wirelessly between the electromagnetic stylus and the electromagnetic touch panel, and can have no power supply in the electromagnetic stylus. In recent years, Such devices are increasingly used in fields such as human-comp...
