Abstract
In a method for displaying information in a motor vehicle, a plurality of objects are represented graphically with the aid of a display mounted in a motor vehicle. A user-interface device generates graphics data which control the display such that the graphical objects are shown disposed on a virtual, perspectively displayed ring, and that in response to an input with the aid of an input device, an arithmetic logic unit of the user-interface device alters the graphics data such that the graphical objects on the virtual ring rotate like a carousel. A corresponding display device is provided.
Claims27
A method for displaying information in a motor vehicle, comprising:
- graphically representing a plurality of objects in a display mounted in the motor vehicle;
- generating, by a user-interface device, graphics data adapted to control the display to show graphical objects disposed on a virtual, perspectively displayed ring;
- and
- altering, by an arithmetic logic unit of the user-interface device, the graphics data in response to an input by an input device to rotate the graphical objects on the virtual ring in the manner of a carousel;
- wherein a duration of a total rotation is between 2 and 3 seconds.
