Abstract

In a method and a device for controlling the display on a display area of a display device in a transportation device, data are generated for the display of a background region and data for the display in a subregion of the display area. The display in the subregion covers the display of the background region, and the display content in the subregion displays at least a portion of the display content of the background region covered by the subregion in a different manner than in the background region. The subregion in the display is shifted relative to the display content of the background region, or the display content of the background region is shifted relative to the subregion, the display content in the subregion being updated in the process, so that, in the new relative position between the subregion and the display content of the background region, it continues to display at least a portion of the display content of the background region covered by the subregion in a different manner than in the background region.

the graphics control unit configured to generate display data as a function of the input signal shifting the display content of the background region, to display the display content of the background region shifted relative to the subregion and to update the display content in the subregion, so that, in a new relative position between the subregion and the display content of the background region, the display device continues to display at least a portion of the display content of the background region covered by the subregion in a different manner than in the background region;

the graphics control unit configured to vary at least one of (a) a category type of the display displayed in the display content in the background region and/or (b) the category type of the display displayed in the display content in the subregion;

wherein the category type of the display displayed in the display content in the background region is changeable independently from the display displayed in the display content in the subregion and the category type of the display displayed in the display content in the subregion region is changeable independently from the display displayed in the display content in the background region;

wherein the display content in the subregion is adapted to display at least a portion of the display content of the background region covered by the subregion at a different scale than in the background region; and

wherein, in a zoom mode, the respective display content in only one of the background region and the subregion is selectively zoomed depending on the detected position of the object in the vicinity of the display area;
