- Haptic interfaces for control are known, for example, from European Patent Publication EP2065614A1, which discloses an assembly for influencing magnetic field properties for the purpose of modulating torque transfer between a rotary member and a haptic interface housing.
- control devices based on magnetorheological actuators are capable of making selections and providing control signals in a wide variety of ways.
- control applications particularly in a vehicle where operating modes can be selected with such a device, there is a need to limit the device's selection capabilities to prevent a user from entering commands that are appropriate for the device.
- controlled system or the controlled machine can be destructive. In vehicles, the lack of such restrictions can even lead to life-threatening situations.
- the object of the invention is therefore the introduction of a rotation control device that can be operated safely.

- the processing unit is configured to issue command signals to the assembly such that the assembly influences the characteristics of the magnetic field to prevent rotation of the user interface interface from the first orientation to the second orientation based on a current operating mode of the vehicle.
- the processing unit is configured to issue command signals to the assembly such that the assembly influences the characteristics of the magnetic field such that rotation of the user interface interface from the first orientation to the second orientation based on data stored in a memory of the device stored with respect to the control signal, which is transmitted from the communication interface immediately before, is prevented.
