Abstract
A control circuit controls an input apparatus to be used underwater. A sense pin is coupled to a sensor electrode arranged so as to allow the user wearing equipment to touch the sensor electrode. A capacitance sensor is coupled to the sense pin, and detects the electrostatic capacitance formed by the sensor electrode. When the electrostatic capacitance Cs detected by the capacitance sensor becomes lower than a predetermined threshold value, the processing unit judges that a touch input by the user has occurred.
