1. A system and device within the system for enhancement of visual perception in a viewer of a two-dimensional image comprising: a) a two-dimensional image displayed on an image surface; and b) at least one real physical visually identifiable object placed in front of the image surface to create a combined scene with the two-dimensional image within the binocular field of view of the viewer, so that binocular images of the combined scene are formed in the viewer, wherein: 1) the ratio of the distance of said at least one real physical visually identifiable object from and in front of the image surface, to the horizontal width of the two-dimensional image is within a range having a minimum value of about 0.05 and a maximum value of about 0.5; 2) the ratio of the horizontal width of said at least one real physical visually identifiable object, to the horizontal width of the two-dimensional image is within a range having a minimum value of about 0.01 and a maximum value of about 0.05; and 3) the ratio of the distance of said at least one real physical visually identifiable object from and in front of the image surface, to the average distance from the viewer to the points of fixation of the viewer on the image surface is within a range having a minimum value of about 0.02 and a maximum value of about 0.2; and 4) said at least real physical one visually identifiable object is an entity distinct from the two-dimensional image, shaped so as to be identifiable, and visually discernable by the viewer as a distinct entity; having the effect of enhancement of the viewer's visual perception in viewing the two-dimensional image by and/or with the fusion of said binocular images of the combined scene in the viewer.
