Abstract : The work at Columbia has concentrated on 4 matters: (1) Experimental work aimed at determining the aspects of individual lines and combinations of lines in the visual field that generate the substantial influence on the visual perception of eye level (VPEL). (2) Experimental work aimed at determining the aspects of individual lines and combinations of lines on the visual perception of the vertical (VPV) and visually perceived straight ahead (VPSA) & their connections with the VPEL. (3) Experimental work aimed at measuring the involvement of extraretinal control of VPEL including effects of head and eye position. (4) Theoretical work on a quantitative model of the mechanism controlling the visual influence on VPEL, VPV, and VPSA, the Great Circle Model (GCM).
