Probably one of the most important of the visual clues by which a person can estimate the relative distances and positions of objects in space is stereoscopic localization. These clues arise from the disparities between the two retinal images caused by the slightly different points of view of the two eyes. That stereopsis is the means for the most accurate discrimination of the relative distances of objects is, of course, universally appreciated. It has not been sufficiently recognized, however, that stereoscopic vision also plays an important role in the subjective orientation of all objects in the entire binocular visual field, in the sense of a rotation about the point of fixation. In the absence of strong perspective clues, this particular capacity may provide one of the important visual criteria by which a person can orient himself in the outside world of objects.

Certain experiments which demonstrate a relation . . . [Full Text PDF of this Article]
