Abstract: A method and device for selecting input fields displayed on a screen and/or for activating input content displayed in a selected input field on the screen by manual inputs into an input area of an input interface. The input interface is designed for the haptic input of gestures into the input area, in order to control the selection of an input field, and for the activation of input content of a selected input field by triggering an electrical switching function of the input interface by means of exerting a predefined minimum force on the input area. A displacement vector V(POS(t1),POS(t2)) is determined from determined input positions POS(t1),POS(t2) of a manual, continuous input of gestures into the input area at a first point in time t1 and a second point in time t2, where t:=time and t1<t2. An absolute value |F(t)| of a surface area F(t), with which the manual gesture input acts on the input area is determined.

Abstract: A method for generating a haptic feedback on a display area operable by finger movements involves sensing a position of a finger on the display area and modulating a coefficient of friction between the finger and the display area is modulated depending on the position. The touchdown positions of two fingers are determined and the friction between each of the fingers and the display area is changed depending on a distance from the touchdown positions of the fingers simultaneously touching the surface.
