Abstract: Touch-sensitive operating apparatuses having a touchscreen which generates a haptic feedback in the event of an actuation of a virtual operating element and methods for operating functions. The method includes representing a virtual operating element on a display surface, detecting touch positions on a touch surface of a touch-sensitive position detection apparatus, detecting press-on forces in the event of a touching actuation of the touch surface, evaluating the detected touch positions and press-on forces, determining whether a correct haptic actuation of the virtual operating element is present, initiating a function assigned to the at least one virtual operating element, and generating a haptic feedback at the touch surface. The operating apparatus has a haptic controller which, on the basis of the press-on forces determined, generates two different haptic feedbacks in the event of an actuation process of a virtual operating element.
