CALIBRATING METHODOLOGY OF STYLUS PRESSURE MAPPING CURVE FOR MATCHING MICROSOFT® WINDOW 10 STANDARD IN MASS PRODUCTION

摘要

The invention provides a method for calibrating stylus pressure mapping curve. First of all, data of average pressure sensing signal values are generated. Then data of standard pressure levels are generated. Next a standard pressure level mapping curve of average pressure sensing signal values via standard pressure levels is generated. Then a pressure sensing signal value of a stylus under calibration is generated. Next the calibrated pressure sensing signal value is compared with the average pressure sensing signal value to generate a calibration reference value, wherein the calibrated pressure sensing signal value and the average pressure sensing signal are corresponding to the same weight applied on the stylus. Finally, data of pressure sensing signal values of the stylus is calibrated by the calibration reference value, thereby mapped to the pressure levels matching the standard pressure curve via the standard pressure level mapping curve.
