What are autostereograms, who created them, when, and where?

An autostereogram is a single-image stereogram (SIS), designed to trick human eyes and brains into seeing a three-dimensional scene in a two-dimensional image. The simplest type of autostereogram consists of horizontally repeating patterns and is known as a wallpaper autostereogram. The Magic Eye series of books features another type of autostereogram called a random dot autostereogram. In order to 'see' 3D images in these autostereograms, the brain must decouple focusing operations of the eyes from convergence. A random dot autostereogram encodes a 3D scene which can be 'seen' with proper viewing technique.History In 1838, Charles Wheatstone, a British inventor, discovered stereo vision (binocular vision) which led him to construct a stereoscope based on a combination of prisms and mirrors to allow a person to see 3D images from two 2D pictures (stereograms).

There are also some really great ones out there if you do an image web search for "autostereogram." Sep 08 06, 2:45 PM

My daughter has several of those Magic Eye books...they're cool but after a bit I have to put them down...they strain my eyes too much....she loves them though. Sep 08 06, 3:06 PM

They are very interesting, but after awhile I can't see straight. It's amazing how simple dots can be combined to make pictures like that. Sep 08 06, 3:31 PM
