Abstract
In a method for performing a touch determination with a capacitive sensor, a self capacitance measurement of a capacitive sensor is initiated, wherein at the same time a mutual capacitance measurement including the capacitive sensor is performed. Such a method can be performed such that the self capacitance measurement and the mutual capacitance measurement differentially cancel with ungrounded conductive objects approaching or touching the capacitive sensor and additively combine for grounded objects approaching or touching the capacitive sensor.
