1. A multi-view display controller, wherein said multi-view display controller is configured to:
control, for at least one pixel area of a multi-view display, the multi-view display to project media data of a media content in a plurality of view directions, the plurality of view directions including a first view direction and a second view direction;
obtain position information representing a current position of a viewer relative to said multi-view display;
determine a set of one or more current view directions for said viewer based on said position information representing the current position of the viewer, said set of current view directions including the first view direction but not the second view direction;
after obtaining the position information, select a set of one or more additional view directions based on the current position of the viewer, wherein the set of additional view directions includes the second view direction and further wherein the display controller is configured to select the set of additional view directions based on the current position of the viewer such that the selected set of additional view directions does not include any view direction that is included in the set of current view directions; and
control the multi-view display to project additional information in each direction included in the set of additional view directions and only in each direction included in the set of additional view directions, wherein
the set of additional view directions is selected such that the viewer must move from the current position to another position in order to view the additional information,
the media data of the media content and the additional information are concurrently projected in the second view direction,
the display controller is configured to detect that the viewer has moved to a new position, wherein the new position is aligned with the second view direction,
the display controller is further configured such that, after detecting that the viewer has moved to the new position, the display controller determines whether the viewer has remained in the new position for at least a predetermined duration of time; and
the display controller is further configured to control the multi-view display to cease projecting the additional information in the second view direction with which the new position is aligned as a result of determining that the viewer has remained in the new position for at least the predetermined duration of time.
