1. A system comprising:
a display configured to contemporaneously project a plurality of views, wherein each view of the plurality of views is projected in a different spatial direction;
a tracking sensor proximal the display configured to determine at least one of a number of viewers within a threshold distance of the display or a pose of a face or eyes of the viewers; and
a processor configured to lenticularize the plurality of views;
wherein the display is operable in a tracked mode and an untracked mode;
wherein in the tracked mode, at least one of the plurality of views is modified based on the pose of the face or the eyes of the viewers prior to lenticularizing the plurality of views, wherein the display operates in the tracked mode when a number of viewers is at most a threshold number of viewers; and
wherein in the untracked mode, the plurality of views are lenticularized without modifications based on the pose of the face or the eyes of the viewers, wherein the display operates in the untracked mode when the number of viewers is greater than the threshold number.
