Abstract
A touch panel system includes an electrostatic capacitance type touch panel including a drive electrode, a position detection electrode, and a pressing force detection electrode; and a controller configured to provide a drive signal to the drive electrode and acquire a position signal value from the position detection electrode and a pressing force signal value from the pressing force detection electrode. The controller detects a position of a pointer based on the position signal value, and acquires a pressing force generated by the pointer based on a rate of change of a smoothed value of the pressing force value based on the pressing force signal value.
