Classification: CPC G  H | IPC G

Claim 14:
15. A method of controlling a sensor system, the sensor system comprising a sensor operable to generate a sensor signal indicative of a user input, the method comprising:
determining whether a defined user input has occurred based on the sensor signal; and
controlling a system parameter based on the sensor signal so that operation of the sensor system is dependent on the sensor signal;
wherein the system parameter controls one or more of:
a scan rate at which samples from the sensor are obtained or processed by the input determination block or the parameter control block;
a conversion time, being a period of time over which a sample from the sensor is captured for conversion into a digital sample;
an amplitude, phase or frequency of a drive signal used to drive the sensor;
a voltage level of a supply voltage used to power at least one of the sensor, the input determination block and the parameter control block;
a clock frequency of a clock signal used to control at least one of the sensor, the input determination block and the parameter control block;
whether one or more components of the system are disabled or operated in a low-power mode;
whether signal filtering of the sensor signal is performed;
a signal-to-noise ratio of the sensor signal; and
power consumption of the sensor system.
