arranged. The instrument cluster is used in particular to display the
Speed, tank contents, cooler temperature and
other operational information of the vehicle.
The increase in electronic equipment in the vehicle has made it necessary
to display a larger amount of information in the vehicle.
For example, modern vehicles include a variety of driver assistance systems,
whose information must be displayed in the vehicle.
Furthermore, vehicles often include a navigation system.
By means of such a navigation system, digital
geographical road maps with a route and, where appropriate
Additional information will be displayed. Finally, include

In reference to 1 the structure of the embodiment of the device according to the invention is explained:
The device comprises a display device 1 with a display area 2 , which is arranged in the interior of the vehicle so that it is clearly visible and easily accessible by at least one vehicle occupant, in particular the driver. The display area 2 can be provided by a display, in particular a liquid crystal display, of any type.
The display device is provided with a control device 3 coupled. The control device 3 generates graphics data by means of the display device 1 can be displayed. The control device 3 is also with a vehicle bus 5 via which it can bidirectionally exchange data with various vehicle equipment. The vehicle devices may be of the control device 3 In particular, provide data for display contents of various widget objects that - as will be explained later - on the display area 2 can be played back.
By means of the control device 3 will be on the display area 2 in a fixed position, a graphical object 6 displayed. The graphic object 6 is represented in particular as a virtual drawer.
Furthermore, an operating device is provided, via which the user can make inputs. About this operating device, the user can in particular the information display on the display surface 2 Taxes. The operating device comprises a touch-sensitive surface 4 on the display area 2 the display device 1 is trained. The display device 1 thus includes a so-called touch screen.
The operating device may further comprise a device 7 for detecting a gesture in front of the display area 2 is executed without it being necessary for the display area 2 is touched. For example, a user's hand or finger may be in front of the display area 2 to do the gesture. From the detection device 7 This is the three-dimensional position of the hand in a certain location area in front of the display area 2 detected. The authorized residence area depends on the layout of the display area 2 in the vehicle. The range should be chosen so that the Stay of a user's hand, in this common area clearly with an operation of the detection device 7 can be associated. The limit of the residence area can z. B. in a range of 40 cm to 10 cm in front of the display area 2 lie. Will the user's hand be closer than this threshold to the display area 2 moved, this is from the detection device 7 recognized and the approach is interpreted as the intention to operate. The detection device 7 Detects the position and movement of the user's hand in the location area. Various gestures executed by the hand are recognized and interpreted as inputs.
The detection device 7
can z. B. infrared light sources and infrared light receiver, which detect the hand-reflected infrared light. Details of such a detection device are in the DE 100 58 244 C2
whose relevant disclosure content is hereby incorporated into the present description. Other detection devices that can be used in conjunction with the display device are described in the following publications: DE 103 05 341 A1
and DE 10 2004 048 956 A1
Further, the position of the hand and its temporal change
also be detected by means of an optical system. In this
System emits a light-emitting diode z. B. rectangular
amplitude modulated light. This light will be detected at the
Object, d. H. the hand, reflects and gets to the reflection
a photodiode. Another light emitting diode emits
also rectangular amplitude modulated light
to the photodiode, which is, however, 180 ° out of phase.
In the case of the photodiode, the two light signals are superimposed
and cancel out if they have exactly the same amplitude. If
If the signals at the photodiode do not cancel each other, the light emission becomes

Control signal derive a signal which for the position
of the object is characteristic.
The following is related to the 2 to 4 an embodiment of the method according to the invention explained, which is carried out by the device described above:
In 2 is the ad on the display area 2 shown in the initial state. In the background becomes a geographical map 8th displayed. In the upper part of the display area 2 becomes this geographical map 8th overlays the graphic object 6 displayed. The graphic object 6 can be selected by the user on the touch-sensitive surface 4 taps at the position where the graphic object is 6 is shown. Alternatively, the user can use the graphic object 6 by a gesture from the gesture detection device 7 defined residence area are selected. The gesture involves a user's hand movement that corresponds to pulling out a drawer. This gesture is done by the gesture detection device 7 captured and as a selection of the graphical object 6 interpreted.
The control device 3 then controls the display area 2 so on, that instead of the graphic object 6 a list of widget representatives 9 is shown. There will also be a button 10 indicated, by means of which one back to the in 2 Display shown can get. If the display area 2 is not big enough to include all the widget representatives in the list 9 a control can be displayed with which a scroll in the list can be generated.
Alternatively to the in 3 given display, the list can also be displayed in the form of a carousel. In this case, the widget representatives 9 shown on a perspective shown ring. This ring can be rotated in particular by a gesture, so that any widget representatives 9 can be displayed.
The user can now by an operation any widget representative 9 Remove from the list and on the display area 2 position. For this purpose, the user can, for example, the touch-sensitive surface 4 touch at a position where a widget representative 9 is displayed, and then on the touch-sensitive surface 4 to a position on the display surface 2 that is outside the representation of the list, glide. There, the user can touch from the touch-sensitive surface 4 to solve. In this case, the widget representative becomes 9 with which the operation has been performed is no longer shown in the list. Instead, it becomes a widget object 11 on the display surface 2 displayed, which is assigned to the widget representative. An ad with multiple widget objects 11 is in 4 played.
If the user wants a widget object 11 again from the display area 2 As described above, he can first remove the graphic object 6 select, whereupon the list, as in 3 shown, is played. Then he can by means of the touch-sensitive surface 4 or a gesture in front of the display area 2 Drag the widget object back to the list. The widget representative associated with the widget object is then returned to its original position in the list and the widget object 11 is no longer on the display area 2 displayed.
