Disclosed herein is a method executed by a device that is configured to be able to detect a pointed position of a stylus on an operation plane being superimposed on a displaying part. The method includes receiving feedback information relating to a display position of a predetermined pattern on the displaying part from a host processor, updating at least some of plural position calibration values stored in a correction table that stores therein the position calibration value for each of plural positions arranged on the operation plane, on a basis of the received feedback information, detecting a tentative pointed position of the stylus, reading the position calibration value that corresponds to the tentative pointed position from the correction table and deriving an output position by correcting the tentative pointed position on a basis of the position calibration value, and reporting the output position to the host processor.
