The invention relates to an input method having haptic feedback, comprising the following steps: providing an actuating element (2), which is mounted for vibration around a resting position (0) in a vibration direction (S), an electromechanical actuator (4, 5) for acting on the actuating element (2) in the vibration direction (S) in a vibration-inducing manner, sensing means (6) for sensing at least one start of manual touching and/or actuation of the actuating element (2), and a control unit (8), which is electrically connected to the sensing means (6), for producing an electrical control signal (S(t)), which comprises, in temporal sequence, an electrical inducing signal (A(t)) and an electrical braking signal (B(t)) for controlling the electromechanical actuator (4, 5); inducing a specified vibration (X(t)) of the actuating element (2) in the vibration direction (S) in order to produce haptic feedback by means of the electromechanical actuator (4, 5) from the electrical inducing signal (A(t)) with or after sensing of the start of the manual touching and/or actuation of the actuating element (2) by the sensing means (6); and braking the vibration (X(t)) of the actuating element (2) by producing a braking action on the actuating element (2) in the vibration direction (S) by means of the electromechanical actuator (4, 5) from the electrical braking signal (B(t)), characterized in that the amplitude spectrum (X(f)) of the vibration (X(t)) in the vibration direction (S), which vibration is measured at the actuating element (2) and results from the inducing and braking, has a limit frequency (fGR) with associated limit amplitude (X(fGR)), the amplitude spectrum (X(f>fGR)) from this limit frequency (fGR) with increasing frequency remaining under the limit amplitude (X(fGR)), the limit amplitude being defined by a drop to 70% relative to a maximum amplitude (X(f0)) of the amplitude spectrum (X(f)), and the limit frequency (fGR) lying in a range below 120 Hz, preferably in a range below 100 Hz, more preferably in a region below 90 Hz.
