Document Summary

Cues to depth: physiological (2 cues, ciliary muscles- extraocular muscles. 2: pictorial cues (7 cues) 7 perspectives discussed in last lecture: motion based cues, relative motion/motion parallax. Can get info about how close things are based on fixation point. Closer than point you"re fixing- seems to be going in opposite direction than you. Man on train going forward fence moving backwards. Further away from you- seems to be going in same direction on you. Trees moving with you: accretion/deletion ** go over in text. Looming- when something suddenly gets larger in front of you. Motion in depth here from beginning- baby sitting looking at tv. Squares growing in visual field, reacts and moves back. Rely on fact that left and right eye have different points of view. Can use that info to see how far away. Distance your thumb is from eye changes point.
