1. A method for detecting an adjusting movement of an adjusting element located on a display area in a motor vehicle, the adjusting element operating at least one function, the method comprising:
- using at least part of light emitted from the display area to detect the adjusting movement of the adjusting element by;
forming at least one region with an optical coding in one part of the display area;
converting light radiated from this region into a light signal; and
detecting and evaluating the light signal using a light detection and evaluation unit to detect the adjusting movement of the adjusting element.

Abstract
A method for detecting an adjusting movement of an adjusting element located on a display area in a motor vehicle, the adjusting element serving for operating at least one function. At least part of the light emitted from the display area is used for detecting the adjusting movement of the adjusting element. This makes a reliable detection of the adjusting movement possible. A compact and robust device for carrying out the method is also disclosed.

9. A device for detecting an adjusting movement of at least one adjusting element in a motor vehicle, the at least one adjusting element operating at least one function, the device comprising:
- at least one display area;
at least one adjusting element mounted on the at least one display area;
a diaphragm with at least one opening;at least one light detector and corresponding evaluation logic; and
at least one light guide,wherein, in response to an adjusting movement of the at least one adjusting element, operator control of the at least one function is carried out, wherein an optical coding is present or produced on the at least one display area in a region of the at least one adjusting element, wherein the at least one opening of the diaphragm is arranged over the optical coding, wherein the at least one light detector detects at least part of light emitted from the at least one display area as an indication of the adjusting movement of the at least one adjusting element, wherein light produced by the at least one display area passes through the at least one opening in the diaphragm in the region of the coding and is input, by way of the at least one light guide, to the at least one light detector for evaluation by the corresponding evaluation logic. - View Dependent Claims (10, 11, 12, 13, 14, 15)
