Abstract
A method for determining the position of an actuation element, e.g. a finger of a user, in a motor vehicle when the element approaches a surface and to a position determination device, has the following steps: generating an HF signal; coupling the HF signal into the user; transmitting the HF signal via the body of the user; receiving the HF signal that has been transmitted via the body and the actuation element, using several sensors and determining the position of the actuation element using sensor signals of the sensors, the sensor signals forming a measurement for the received signal intensity of the HF signal and are used to first calculate the position of the centre of gravity of the approaching object, in particular the approaching body part comprising the actuation element, and the position of the actuation element is calculated, taking into consideration the position of the centre of gravity.
