1. An apparatus comprising:
- 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 comprising an input configured to receive, during a first time, an input signal comprising a time varying component and an output configured to provide, during the first time, a time varying output signal that depends simultaneously upon both a time variation of the capacitance of the capacitance touch sensor arrangement during the first time in response to a user touch, and a time variation of the resistance of the variable resistance sensor during the first time in response to a sensed parameter.
