Abstract: Provided is a touch panel system including a touch panel and a controller. The controller includes a signal acquisition unit that acquires a signal value from a position detection electrode and acquires a signal value from a pressing force detection electrode, a position detection unit that detects a position of a pointer, based on a position signal value acquired by the signal acquisition unit, and a pressing force determination unit that determines a presence or absence of a pressing operation at a pointed position. The pressing force determination unit acquires a second derivative value of a pressing force value and determines the presence or absence of the pressing operation at the pointed position, based on the second derivative value.
