1. A method, comprising:
detecting an input made by a finger on a touch-sensitive capacitive operating element comprising at least two capacitive sensors;
calculating a finger position using sensor strokes of individual capacitive sensors of the at least two capacitive sensors at a same time,
wherein the calculated finger position is not output when a difference between a maximum and minimum sensor stroke of the at least two capacitive sensors is smaller than a first preset value, and
wherein the calculated finger position is output when the difference between the maximum and minimum sensor stroke of the at least two capacitive sensors is greater than the first preset value, and when the sensor stroke of a capacitive sensor, of the at least two capacitive sensors, closest to the calculated finger position at an edge of the touch-sensitive capacitive operating element is smaller than a second preset value.
