Method for recognizing an orientation of a hand of a user, comprising the steps of: - detecting the hand of the user by means of a sensor , - determining a plurality of surface points of the hand in the sensor signal, wherein the plurality of surface points comprises at least one center point of the hand and a plurality of surface points arranged essentially in a circular shape around the center point , - determining a distance of the respective surface points from the sensor for determining whether the surface points are essentially situated on a concave surface with respect to the sensor or on a convex surface with respect to the sensor , wherein a concave surface is determined if the center of the hand, from the perspective of the sensor , is arranged behind a line or plane determined by the plurality of surface points arranged around the center point ; wherein the line is determined by two surface points opposite one another with respect to the center point , and the plane is an averaged plane placed through the surface points arranged around the center point , or through all surface points ; and wherein a convex surface is determined if the center point of the hand, from the perspective of the sensor , is arranged in front of line or plane defined by the plurality of surface points arranged around the center point , - recognizing an inner hand surface facing the sensor if it is determined that the surface points lie essentially on a concave surface with respect to the sensor , and/or - recognizing a back of a hand facing the sensor if it is determined that the surface points lie essentially on a convex surface with respect to the sensor . - detecting the hand of the user by means of a sensor , - determining a plurality of surface points of the hand in the sensor signal, wherein the plurality of surface points comprises at least one center point of the hand and a plurality of surface points arranged essentially in a circular shape around the center point , - determining a distance of the respective surface points from the sensor for determining whether the surface points are essentially situated on a concave surface with respect to the sensor or on a convex surface with respect to the sensor , wherein a concave surface is determined if the center of the hand, from the perspective of the sensor , is arranged behind a line or plane determined by the plurality of surface points arranged around the center point ; wherein the line is determined by two surface points opposite one another with respect to the center point , and the plane is an averaged plane placed through the surface points arranged around the center point , or through all surface points ; and wherein a convex surface is determined if the center point of the hand, from the perspective of the sensor , is arranged in front of line or plane defined by the plurality of surface points arranged around the center point , - recognizing an inner hand surface facing the sensor if it is determined that the surface points lie essentially on a concave surface with respect to the sensor , and/or - recognizing a back of a hand facing the sensor if it is determined that the surface points lie essentially on a convex surface with respect to the sensor . <EOS>
