Abstract
A stylus includes a processor that acquires first coordinate values in a pen coordinate system at an occurrence position of a pen event detected by a pen sensor and acquires second coordinate values in a device coordinate system at the occurrence position of the pen event. The processor uses a plurality of sets of coordinate value pairs to determine conversion parameters for converting coordinates from the pen coordinate system into the device coordinate system and uses the determined conversion parameters and a measured amount of movement of the stylus to calculate coordinate values of the stylus in the device coordinate system.
