(52) The central unit 500 may be configured to include the virtual barrier 210 in the image data S200 so that a position of the virtual barrier 210 and the position of the marking 458 overlap in a view of the user 700 of the vehicle 100. A virtual point 411 of the marking 458 in the surrounding 400 of the vehicle 100 may be ascertained based on the recorded image. In the view of the user 700 at least one point 211 of the virtual barrier 210 may be aligned to the virtual point 411 by means of the central unit 500, wherein the alignment is based on the user's point of view 301.

(53) According to one embodiment of FIG. 6 the virtual barrier 210 is a red semi-transparent wall placed on the white marking 458 on the road.

(54) The invention is not limited to the shown embodiments in FIGS. 1 through 6. For example, it is possible to provide other virtual barriers, such as semitransparent curtains, crash barriers, or the like. It is also possible to change properties of the virtual barrier, such as the degree of transparency or the color or brightness depending on the distances to the recognized objects. It is likewise possible to output the virtual barrier also depending on traffic rules to indicate, for example, the unallowable entry into a one-way street. The virtual barrier can be used, moreover, for displaying maneuver instructions, in order to prevent entry into a wrong street. The functionality of the system according to FIG. 2 can be used especially advantageously for an infotainment system.
