User interface for controlling functions of e.g. audio system in motor vehicle, has control unit connected with sensor for controlling feedback unit such that rotational positions of actuator are programmed based on haptic feedback

摘要

The interface has a sensor (7) detecting rotation of an actuator (2), and a feedback unit (10) generating a haptic feedback with respect to the rotation of the actuator. A control unit (8) is connected with the sensor for controlling the feedback unit such that the discrete marker rotational positions of the actuator are programmed in the control unit based on the haptic feedback by touch. The control unit is connected to a display screen (9) for displaying the changing icon information.
