Abstract
A method for detecting an operating input performed by a finger involves detecting various contact points of a contour of the finger using a sensor system on a sensor surface. The sensor system includes at least one transmitting unit for transmitting a signal to the finger and at least one receiving unit for receiving a signal reflected by the finger. A surface vibration is introduced into the sensor surface by at least one actuator, the surface vibration changes the frictional resistance between the finger and the sensor surface as a function of the changing contact points of the contour of the finger.
