Different Cues Affect Binocular And Monocular Vision

Many researchers are interested in depth perception and how different cues affect what is seen. There have been lots of studies done around depth perception. Some have done studies on how different cues affect binocular and monocular vision in depth perception (Reinhardt-Rutland, 1996). Others have studied how depth cues are used in tasks like computer- and video-based tasks (Westerman & Cribbin, 1998).
Visual depth perception is using cues to perceive the world in three dimensions and the distance of objects. There are many cues to help with depth perception. They can be categorised in either binocular vision (two eyes) or monocular vision (one eye). Binocular only has physiological cues (retinal disparity and convergence). Monocular has physiological cues (accommodation and motion parallax) and pictorial cues (interposition, elevation, texture, linear perspective, shading, aerial perspective, and familiar and relative size). Pictorial cues can be in two dimensions and doesn’t need motion (Westerman & Cribbin, 1998) whereas the other three (binocular, monocular and physiological) use motion and three dimensions. Monocular vision comes from changes of each eye connecting to distance. The most importance is accommodation. This is the change of lens curves needed to maintain a sharp image on the retina. With the way that monocular changes occur it is said that this influences depth perception most strongly. Monocular vision doesn’t really affect depth perception but it does
