Abstract
An apparatus including a capacitance touch sensor arrangement configured to have a variable capacitance that varies when a user finger touches the capacitance touch sensor arrangement; and at least one variable resistor sensor integrated within the capacitance touch sensor arrangement wherein the variable resistor sensor has a variable resistance that varies with a sensed parameter; the apparatus including an input configured to receive an input signal including a time varying component and an output configured to provide an output signal that depends upon both the capacitance of the capacitance touch sensor arrangement and the resistance of the variable resistance sensor.
