Do My Eyes Deceive Me? The Science of How Humans See the World

Andrew Shatte – University of Arizona

It is estimated that humans get 80% of their information about the world through their eyes and so the science of vision has fascinated us for centuries. Human vision performs a remarkable feat; it glimpses a 3-D world, represents it as 2-D on the eye, and then uses the brain to reconstruct it as a 3-D perception.

In this highly energetic and interactive session, Dr. Shatté takes you on a whirlwind tour of the journey from eye to brain, using the classic visual illusions to illustrate what we know about how we make sense of our world. What do case studies tell us about our eyes and our brains (like the man who saw the world upside down, the people who can't recognize faces, or those who can't see movement or depth)? Join us as we unpack how humans see the world.
