Abstract: A control method for a user interface system may include receiving an input signal, receiving a temperature signal indicative of a temperature, generating a baseline signal based on at least one among the input signal and the temperature signal, calculating an error signal based on a difference of the input signal and the baseline signal, and modifying the baseline signal based on the error signal.

Abstract: A method may include receiving an input signal, generating a baseline signal based on the input signal, generating a corrected input signal by subtracting the baseline signal from the input signal, determining a threshold level change of the input signal when the corrected input signal exceeds a level change threshold, and responsive to the threshold level change, updating the baseline signal to the level change threshold.
