Abstract

A position detection method performed using a capacitive touch sensor with line electrodes two-dimensionally arranged. The method includes: acquiring first two-dimensional data indicating a first distribution of detection values of capacitance on the touch sensor; recognizing that a foreign object is present in an area on the touch sensor based on the first two-dimensional data; in response to the recognizing that the foreign object is present in the area on the touch sensor based on the first two-dimensional data, using a first threshold that is lower than a second threshold for detecting a first touch position or touch area inside of the area on the touch sensor in which the foreign object is present; and detecting the first touch position or touch area inside of the area on the touch sensor in which the foreign object is present based on the first two-dimensional data and the first threshold.
