1 1. Depth perception
• Depth perception results from a
combination of binocluar & monocular
Info from one eye- 2 monoculor cues. Both eyes- binoculor 7
Even if you poke one eye out you can still perceive some depth 1. Depth perception
i.Retinal disparity: objects at
different distances fall on different
locations on the retina.
The farther an object the location changes on the retina. Neurons calculate
where on retina and calculates how far object is. Disparity on retina is a cue our
eyes use 1. Depth perception
i.Convergence: Your brain controls
extraoccular muscles so it can
calculate the angle between the eyes.
Brain controls muscles to calculate angle between the eyes. The closer the angle
the father away(?) 1. Depth perception
i)if something is closer to you it blocks things that are farther away. Ie stand
behind podium, know podium is in front of/blocking legs therefore it is closer.
ii)know as parallel lines go off into the distance they are converging, the closer
these lines are to us the farther away.
ii)the farther away it is the finer and finer the texture/pattern is.
iv)the dust in the atmosphere, the farther away the ima
