SIGNAL EVALUATION METHOD

Signal of inputs made by a finger on a touch-sensitive capacitive operating element are evaluated by calculating a finger position from sensor strokes of individual capacitive sensors. The calculated finger position is not output if a difference between the maximum and minimum sensor stroke of the s...

description Signal of inputs made by a finger on a touch-sensitive capacitive operating element are evaluated by calculating a finger position from sensor strokes of individual capacitive sensors. The calculated finger position is not output if a difference between the maximum and minimum sensor stroke of the sensors is smaller than a preset value or smaller than the error tolerance of the sensors. The finger position is output if the difference between the maximum and minimum sensor stroke of the sensors is greater than the first preset value and if the sensor stroke of a sensor closest to the detected finger position at the edge of the touch-sensitive capacitive operating element is smaller than a second preset value.
