They’re so good at it that you don’t even notice.<BR/><BR/>You can only see at a high-resolution in a fairly small area, and even that has a big fat blind spot right exactly in the middle, but you still walk around thinking you have a ultra-high resolution panoramic view of everything. Why? Because your eyes move really fast, and, under ordinary circumstances, they are happy to jump instantly to wherever you need them to jump to. And your mind provides this really complete abstraction, providing you with the illusion of complete vision when all you really have is a very small area of high res vision, a large area of extremely low-res vision, and the ability to page-fault-in anything you want to see—so quickly that you walk around all day thinking you have the whole picture projected internally in a little theatre in your brain.<BR/><BR/>This is really, really useful, and lots of other things work this way, too. Your ears are good at tuning in important parts of conversations. <BR/>...<BR/></I><BR/><BR/>~ <A HREF="http://www.joelonsoftware.com/items/2007/01/21.html" REL="nofollow">Joel on Software</A> (this is an article on computer software, all of it is not relevant to this post)Anonymousnoreply@blogger.com
