User interfaces and associated apparatus and methods

摘要

Apparatus comprising one or more inputs configured to receive a configurable control signal from a configurable signal generator; and a non-calibrated touch input signal from a touch sensor. Said non-calibrated touch input signal generated by detecting both internal and external forces applied to the touch sensor. The apparatus also comprises a calibrator configured to process the non-calibrated touch input signal and the configurable control signal to remove the contribution of the internal forces from the non-calibrated signal to generate a calibrated signal, the calibrated signal for use in the detection of an external force applied to the touch sensor.
