Dual Measurement for Capacitive Touch Sensing and Related Systems, Methods and Devices
12 May 22
One or more examples relate, generally, to a method for capacitive touch sensing that includes: performing first self-capacitance measurement of an electrode of a touch sensor while a driven shield-signal is provided to at least a portion of shielding of the electrode; determining a first touch sensing result at least partially responsive to determining that a value representing performing first self-capacitance measurement exceeds a first threshold value; performing second self-capacitance measurement of the electrode of the touch sensor while a ground signal is provided to at least the portion of shielding of the electrode; determining a second touch sensing result at least partially responsive to determining that a value representing performing second self-capacitance measurement exceeds a second threshold value, the second threshold value different from the first threshold value; and determining a touch result responsive to both the first touch sensing result and the second touch sensing result being indicative of a touch.
