ABSTRACT:
A pressure sensitive touch pad system, for example employing variable capacitance touch pads, employs low cost transducers subject to parameter drift and periodically (e.g. once each second) re-calibrates each touch pad. The periodic re-calibration allows a low cost transducer to be used for multi-point operation, as well as for simple on/off operation, such as for function selection. One application is to provide different slew rates for setting a data entry indicator, for example indicating the value of an appliance function.
