Method for determining a touch event and touch sensitive device

摘要

The invention relates to a method for determining a touch event provided by a user on an interaction surface of a touch sensitive device comprising the steps of: sensing a raw signal by a transducer, in particular by a piezoelectric transducer and low-pass filtering the sensed signal, segmenting the filtered raw signal into a baseline signal and at least one useful signal, and analyzing the at least one useful signal to determine properties of the touch event.
