  • the flat electrode 1 1, 12 acts with its shape of the continuous conductor similar to an interconnection of capacitor plates of different sizes. Since the electrode sections 1 1 a, 12 a, 1 1 b, 12 b are electrically connected, in principle, a potential equalization on the flat electrode 1 1, 12 instead. Correspondingly, the regions 1 1 a, 12 a react more strongly than the tapered regions 1 1 b, 12 b Approximations or touches. A body part of the user 4, which is moved along the flat electrode 1 1, 12 shown, generates correspondingly different signals, depending on the position, which arise, for example, in the evaluation device 14.
  • each individual flat electrode 1 1, 12 detect an approach of the user 4, as well as a movement of the user 4 in the context of a complex movement pattern 9 along the inventively formed flat electrode 1 1, 12 recognize.
  • This is realized, inter alia, by the fact that the flat electrode 1 1, 12 has areas with different capacitive sensitivity along their extension, as described above. It is also conceivable that the electrode 16 according to FIG. 5 is also designed as a flat electrode just described.
