Our brain is able to look at how much the eyeballs are turned in order to give usĪnother kind of depth cue. Something really close to us, the muscles in our eyes turn our eyeballs towards the object. Things really far away, the muscles in our eyesĪre fairly relaxed. This basically is trying to say that when we're looking at Another way that our two eyes help us take depth into account is something known as convergence. This allows us, this gives us some degree ofĭepth of what we're looking at. Images, puts them together, and gives you this image over here. Them in this angle, and your brain takes these two The bowling pins in this angle, and your right eye sees When you're looking at some pins, your left eye sees the pin, To get slightly different views of objects in the world around us. Basically, since our eyesĪre about 2-1/2 inches apart and this basically allows us Binocular vision basically gives us something known as retinal disparity, retinal disparity.
The first thing that weĬan immediately notice is that humans have two eyes.
In order for us to take intoĪccount depth of objects, we can use a few different tricks. Depth allows us to getĪn idea of how far away something is, how close something is, and just it adds to our One of the things that we can do is take into account depth. Voiceover: How is perception organized? Well, whenever we look at anything, we need to make inferences.
