DETAILED DESCRIPTION OF THE DRAWINGS

[0031] FIG. 1 shows in an upper part a vehicle 100 having an apparatus 105 for presenting information to a person 110 on board the vehicle 100. The apparatus 105 comprises a first display 115, a second display 120 and a processing device 125. Furthermore provided are preferably a scanning device 130 and/or a sensor 135.

[0032] The person 110 can comprise in particular a driver of the vehicle 100. The displays 115, 120 are each configured to present visual and in particular graphically representable information to the person 110. Such information can comprise for example a driving situation of the vehicle 100. It is assumed that the processing device 125 provides information to be presented, although it can also receive such information from a different source, for example from a further control unit on board the vehicle 100.

[0033] The first display 115 is preferably firmly attached to the vehicle 100, and the second display 120 can be movably attached to the vehicle 100. Distances of the displays 115, 120 from the person 110 can differ. In an embodiment, a display area of the first display 115 is larger than a display area of the second display 120.

[0034] The second display 120 may be movable by being attached to an object that is movable in the vehicle 100. In the present case, the second display 120 is attached to a steering wheel 140, for example in a central region or to a spoke of the steering wheel 140. In an embodiment, the second display 120 may be touch-sensitive so as to allow a control input from the person 110. The sensor 135 is configured to determine a position and/or an alignment of the second display 120 relative to the vehicle 100. In the present case, the sensor 135 comprises a steering wheel sensor.

[0035] The person 110 can be scanned by means of the scanning device 130, and a position of the person 110 on board the vehicle 100 can be determined on the basis of the scan. The position can relate in particular to the head 145 and with further preference to an eye 150 of the person 110. The scanning device 130 can comprise a camera, a stereo camera or a depth camera. The position is preferably determined three-dimensionally with respect to the vehicle 100.

[0036] The processing device 125 is configured to determine a constellation of the person 110—or of the person's head 145 or the person's eye 150—in relation to the displays 115 and 120. In particular, the intention is to determine whether the second display 120 is located between the person 110 and the first display 115. In this case, the second display 120 obscures at least a portion of the first display 115 for the person 110. A display content presented on the first display 115 can then be provided on the second display 120. As a result, a content presented on the first display can be continued on the second display 120 for the person 110. The person 110 may be given the impression that the second display 120 is part of the first display 115 and that there is no obscuration.

[0037] In a lower region of FIG. 1, the intended effect is illustrated by way of example. In this case, the steering wheel 140 has, by way of example, a substantially rectangular shape in the manner of a yoke and is rotatable about an axis of rotation 155. If the steering wheel 140 due to its rotation about the axis of rotation 155 obscures the first display, a display content of the first display 115, which serves as an example, is continued as seamlessly as possible on the second display 120. The presentation on the second display 120 is effected in the correct orientation and in the region that is obscured in the first display 115 for the driver 110. The presentations of the displays 115 and 120 can together form a uniform presentation. The presentation can be interrupted only in a portion where the first display 115 is obscured by the steering wheel 140 but where the steering wheel 140 is not covered by the second display 120.

[0038] FIG. 2 shows exemplary presentations on a first display 115 and a second display 120. Here, too, a second display 120 that is rotatable about an axis of rotation 155 and obscures, in dependence on an angle of rotation, different portions of the first display 115 is assumed. In an upper region of FIG. 2, the first display 115 is presented as not being obscured and as being partially obscured by the second display 120 in a lower region.

[0039] A first object 205 and a second object 210 are presented on the first display 115, and a third object 215 is presented on the second display 120. So as not to completely replace the presentation of the third object 215 on the second display with the presentation of a portion of the display content of the first display 115, it is possible to proceed object by object. For this purpose, the objects 205-215 can each be assigned a priority that decides which object 205-215 can be overlaid on another object 205-215. In the present presentation, for example a priority of the second object 210 is greater than a priority of the third object 215, and the second object 210 is therefore overlaid on or obscures or replaces the third object in the presentation on the second display 120.

[0040] Likewise by way of example, the first object 205 has a lower priority than the display content of the second display 120, and for this reason it is not presented at all on the second display 120.

[0041] FIG. 3 shows a flowchart of a method 300 for providing information on a second display 120, which temporarily covers the first display 115 from the perspective of a person 110. The focus is here by way of example on the apparatus 105 of FIG. 1, even though in other embodiments other movements are possible or other devices can be used to determine a position or a movement.

[0042] In a step 305, a steering wheel angle of the steering wheel 140 to which the second display 120 is attached is scanned. On the basis of the steering wheel angle, a position and an alignment of the second display 120 relative to the vehicle 100 can be determined.

[0043] In a step 310, a position of the driver 110, preferably of the driver's head 145 and with further preference of a driver's eye 150, is determined. The position can be determined in particular on the basis of an optical scan by means of the scanning device 130.

[0044] In a step 315, a constellation indicating how the person 110, the second display 120, and the first display 115 are located in the vehicle is determined. On the basis of the constellation, it is possible to determine which portion of the first display 115 is covered by the second display 120 from the perspective of the driver 110. It is furthermore possible to determine which portion of the second display 120 covers the first display 115.

[0045] In a step 320, objects 205, 210, which are presented on the first display 115, and respectively assigned priorities can be determined. In a step 325, an object 215, which is presented on the second display 120, and an assigned priority can be determined. In an embodiment, an entire display content of one of the displays 115, 120 can also be considered to be the object 205-215.

[0046] In a step 330, it is possible to determine, for a portion of the second display 120 that covers a portion of the first display 115, which object 215 presented on the second display 120 is overlaid by or on an object 205, 210 of the first display 115. The display content of the first display 115 can for this reason be imaged onto a display area of the second display 120 by means of a transformation matrix, which can be determined on the basis of the steering angle.

[0047] In a step 335, objects 205-215 can be provided on the second display 120 in accordance with the determined overlay.

[0048] In order to take into account that the position and/or alignment of the second display 120 relative to the first display 115, and also the position of the person 110 relative to the displays 115, 120, can change quickly, it is preferred that a rotational speed and possibly also a rotational acceleration of the steering wheel 140 are taken into account for the determination of a display content that is to be presented on the second display 120. A position and/or alignment of the second display 120 can also be predicted for a future time point.

[0049] Typically, a display 115, 120 on board the vehicle 100 is supplied with frames, which are then provided by the displays 115, 120, at a predetermined frequency. A piece of information that is to be presented on the second display 120 can be determined on the basis of a frame that has been prepared for the visual presentation but has not yet been presented. Information to be presented can thus be synchronized better with respect to one another on the displays 115, 120 and take into account changing circumstances in the constellation.

[0050] The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
