Why is it that I am not able to read a book without moving my eyes if the entirety of the page is within my field of view? Why do I have to center my eyes on an object to observe it fully? And why is it that I am still able to view changes in surroundings in the edges of my field of vision despite there being supposedly no way...
What you perceive is vastly different than a continuous filmstrip. Have you ever tried to watch unstabilized footage from a person jogging? Totally unwatchable! But your brain smooths it out better than the best steadicam. Tilt your head from side-to-side: what you perceive stays upright. And of course you know hat your eyes don’t smoothly pan from subject to subject but are constantly “saccading” around, but your brain processes that all away.
Visual processing is amazingly complex. Its also interesting that our other senses have different levels of processing. Our sense of smell is nothing compared to a dog’s, our sense of hearing is nothing compared to a whale’s, etc. A metaphor I heard once (don’t know how accurate it is) is that when a human walks into a kitchen they might smell that a stew is cooking. A dog would smell both the overall smell but would also smell the individual carrots, peas, chunks of meat, etc.
If we have such a high field of vision, why can't we focus on everything within the vision simultaneously?
