Claim:
1. A method for inputting a control command for a component of a motor vehicle, comprising: acquiring a calibration image for an input object, the calibration image being determined when the input object is at a predetermined position within a predetermined acquisition region, in order to calibrate a skeleton model to the input object; generating an image sequence for the input object, the image sequence being generated by imaging the input object within the acquisition region as the user guides the input object through the acquisition region, the input object being imaged by an imaging device comprising an infrared camera; illuminating the input object within the acquisition region using an infrared source so that infrared light from the infrared source is scattered by the input object back to the camera; identifying a position change of the input object based on the image sequence by: determining position information from a ratio between a size of the input object in the calibration image and a size of the input object in at least one image of the image sequence, and from a position of the input object along an axis parallel to a viewing direction of the camera determined based on a luminous intensity of the infrared light scattered back to the camera; and generating a control command for, and inputting the control command to, the component of the motor vehicle based on the position change and the position information, wherein a duration for which the camera is allowed to be exposed to the infrared light scattered back to the camera is varied cyclically by exposing the camera to the infrared light scattered back to the camera for a first period of time and exposing the camera to the infrared light scattered back to the camera for a second period of time which is greater than the first period of time.
