Abstract
An input device for generating improved haptic feedback. The input device includes a housing and an input component that defines a control surface and is movably supported on the housing with at least two degrees of freedom and associated mechanical natural frequencies. The input device is designed to assign a switching or controlling function to an operator touching or pressing the control surface, where the input device further has mechanical restoring means for restoring the input component into a rest position and an electromechanical actuator, where the actuator is designed to drive the input component along the at least two degrees of freedom and optionally decelerate the input component, counteracting the restoring force caused by the mechanical restoring means, in order to generate haptic feedback characterized in that the mechanical natural frequencies of the at least two degrees of freedom have a maximum deviation of less than 100 Hz.
