Claim 6:
7. The correction unit as claimed in claim 5, configured to calculate the estimation signal using an estimation model whose arguments comprise one or more input variables, the one or more input variables comprising one or more of:
time;
an elapsed time of the user press operation;
a magnitude of the sensor signal;
a rate of change of the magnitude of the sensor signal;
a period of time since a previous user press operation;
a frequency of user press operations;
a determined location of the applied force relative to a location of the force sensor;
a time-domain and/or frequency-domain feature extracted from the sensor signal and/or the corrected signal;
a time-domain and/or frequency-domain feature extracted from, or a magnitude of, at least one sensor signal obtained from another force sensor of the sensor system;
a time-domain and/or frequency-domain feature extracted from, or a magnitude of, at least one sensor signal obtained from another sensor of the sensor system such as a temperature sensor, accelerometer, microphone or camera;
a feedback signal generated by the sensor system in response to the sensor signal and/or the corrected signal; and
a feedback signal input by a user in response to the sensor signal and/or the corrected signal.
