Abstract
The embodiments disclosed herein relate to a method for the capacitive detection of at least a contact of a capacitive sensor by an operator. The method includes providing the capacitive sensor and providing an electronic evaluation system; applying a first constant electric potential to the counter electrode of the capacitive sensor; applying a second constant electric potential, which differs from the first potential, to the counter electrode of the capacitive sensor; calculating a first parameter from the first measured value and the second measured value; calculating a second parameter from the first measured value and the second measured value; and respectively comparing the first parameter and the second parameter with a predefined quantity.
