Abstract

In a method for displaying information in a motor vehicle, at least one two-dimensional object is represented graphically with the aid of a display mounted in the motor vehicle, the graphical object including a display field and an operating field. A user-interface device generates graphics data which control the display such that the display field is shown on one side of the two-dimensional graphical object and the operating field is shown on the other side of the two-dimensional graphical object, and 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 object in the perspective representation on the display rotates from one side to the other side. A corresponding display device is provided for a motor vehicle, and a motor vehicle may include such a display device.

Claims

1. A method for displaying information in a motor vehicle, comprising:

graphically representing at least one two-dimensional graphical object by a display mounted in the motor vehicle, the graphical object including a display field and an operating field;

generating, by a user-interface device, graphics data adapted to control the display to show the display field on one side of the two-dimensional graphical object and to show the operating field on the other side of the two-dimensional graphical object; and

in response to an input by an input device, altering, by an arithmetic logic unit of the user-interface device, the graphics data to rotate the graphical object in a perspective representation on the display from one side to the other side.

2. The method according to claim 1, further comprising:

generating, by the arithmetic logic unit, graphics data for successive intermediate images to represent the rotation; and

subdividing the rotation into a first phase during which pixels of the graphical object are moved in accelerated fashion and a second phase during which pixels of the graphical object are moved in decelerated fashion.

3. The method according to claim 2, wherein the first phase corresponds to an angle of rotation of the graphical object from 0°

to 90°

, and the second phase corresponds to an angle of rotation of the graphical object from 90°

to 180°

.

4. The method according to claim 1, wherein an axis of rotation lies within the graphical object.

5. The method according to claim 2, wherein the calculating of the graphics data for successive intermediate images to represent the rotation in the first phase includes:

(i) calculating

6. The method according to claim 2, wherein the calculating of the graphics data for successive intermediate images to represent the rotation in the second phase includes:

(i) calculating

7. The method according to claim 2, wherein a duration of the rotation of the first phase is between 0.25 second and 1 second.

8. The method according to claim 2, wherein a duration of the rotation of the first phase is between 0.5 second and 0.75 second.

9. The method according to claim 2, wherein a duration of the rotation of the second phase is between 0.25 second and 1 second.

10. The method according to claim 2, wherein a duration of the rotation of the second phase is between 0.5 second and 0.75 second.

11. The method according to claim 2, further comprising:

measuring a speed of the motor vehicle; and

ascertaining at least one of (a) a duration of a total rotation, (b) a duration of the rotation of the first phase, and (c) a duration of the rotation of the second phase as a function of the speed of the motor vehicle.

12. The method according to claim 1, wherein the operating field includes command buttons adapted for input by the input device.

13. The method according to claim 1, wherein the input includes touching the display.

14. The method according to claim 1, wherein the input includes a gesture of a body part of a user performed in front of the display, the method further comprising detecting and evaluating the gesture by the input device.

15. The method according to claim 14, wherein the detecting of the gesture includes detecting a capacitive coupling between the body part and a receiving device.

16. The method according to claim 14, wherein the detecting of the gesture includes detecting an emission of infrared radiation and reflection of the infrared radiation by the body part of the user.
