    Abstract: A touch sensor includes a pressure sensor configured to become compressed along a first axis in response to a touch input into a touch area and a controller. The controller is configured to calculate a position of the touch and an intensity of the touch by using a detection signal obtained from the pressure sensor. The controller is further configured to calculate a first position, which has a greatest value of compression of the pressure sensor along the first axis, and calculate a position of the touch by correcting the first position by a first correction value corresponding to the greatest value of compression.
