APPARATUS AND METHOD FOR DETERMINING A STIMULUS, INCLUDING A TOUCH INPUT AND A STYLUS INPUT

A capacitive sensor associated with a substrate is presented. The electrode includes a self-capacitance; and a processing unit electrically coupled to the electrode and configured to register a first touch signature during a first touch event in response to an object approaching the electrode.

Zusammenfassung:A capacitive sensor associated with a substrate is presented. The electrode includes a self-capacitance; and a processing unit electrically coupled to the electrode and configured to register a first touch signature during a first touch event in response to an object approaching the electrode. The first touch signature occurring over a total time domain (T) between a first time and a second time, between a first substantially constant self-capacitance and a second substantially constant self-capacitance.
