Believing he was on to something, Baccei partnered with graphic artist Cheri Smith, who helped him create more involved images on a computer instead of the generic clip art he had been using. A Pentica co-worker named Bob Salitsky was able to refine the dots for a sharper image. Look at a picture of some tropical fish, for example, and a fish tank would appear. By 1991, Baccei was working on his own start-up, N.E. Thing Enterprises, and taking assignments for the illustrations. One of the images appeared in the American Airlines magazine American Way, where it caught the eye of Japanese businessmen. Soon, Baccei was working with Tenyo Co. Limited on a series of books and posters. While Baccei called the pictures Stare-e-os, the Amazing 3D Gaze Toys, the Japanese sold the images under the name Magic Eye. When one moves one's attention from one depth plane to another (for instance, from the top row of the chessboard to the bottom row), the two eyes need to adjust their convergence to match the new repeating interval of patterns. If the level of change in convergence is too high during this shift, sometimes the brain can lose the hard-earned decoupling between focusing and convergence. For a first-time viewer, therefore, it may be easier to see the autostereogram, if the two eyes rehearse the convergence exercise on an autostereogram where the depth of patterns across a particular row remains constant. At the time, Julesz’s research was heralded as a massive advancement in the understanding of 3-D vision. But it wasn’t until the 1970s when Tyler figured out how to achieve the same 3-D effect with a single image that the roots of modern-day Magic Eye were formed.

The next day, Gregorek called up Baccei and told him that he wanted to make him rich. Courtesy of Ron Labbe/Studio 3D In 1844, David Brewster discovered the "wallpaper effect". [5] He noticed that when he stared at repeated patterns in wallpapers while varying his vergence, he could see them either behind the wall (with wall-eyed vergence) or in front of the wall (with cross-eyed vergence). [6] This is the basis of wallpaper-style autostereograms. [3] Kompaneysky, Boris N. (1939).

Stereoblindness, however, is not known to permit the usages of any of these techniques, especially for persons in whom it may be, or is, permanent.

This autostereogram displays patterns on three different planes by repeating the patterns at different spacings. ( ) It is generally thought that amblyopia is a permanent condition, but NPR reports a case where a patient with amblyopia regains stereo vision ( Susan R. Barry). [24] Scott B. Steinman, Barbara A.

The optical illusion of an autostereogram is one of depth perception and involves stereopsis: depth perception arising from the different perspective each eye has of a three-dimensional scene, called binocular parallax. Tyler, Christopher (2014). "Autostereogram". Scholarpedia. 9 (4): 9229. Bibcode: 2014SchpJ...9.9229T. doi: 10.4249/scholarpedia.9229.R. Kimmel. (2002) 3D Shape Reconstruction from Autostereograms and Stereo. Journal of Visual Communication and Image Representation, 13:324–333. Wallpaper autostereogram is a single 2D image where recognizable patterns are repeated at various intervals to raise or lower each pattern's perceived 3D location in relation to the display surface. Despite the repetition, these are a type of single image autostereogram. Hold the center of the printed image right up to your nose. It should be blurry. Focus as though you are looking through the image into the distance. Very slowly move the image away from your face until the two squares above the image turn into three squares. If you see four squares, move the image farther away from your face until you see three squares. If you see one or two squares, start over! In 1991, N.E. Thing Enterprises began working with Tenyo Co., Ltd, a Japanese company know for selling an array of magic products. This relationship led to the christening of Magic Eye. “We called it Magic Eye because it translated well to Japanese—and because it had ‘magic’ in the name,” Smith recalled. At the time, Tenyo was selling Magic Eye autostereogram posters, postcards, and other retail products. When the company released the first three Magic Eye books later that year, Magic Eye became an overnight sensation. Smooth gradients can also be achieved with an intelligible pattern, assuming that the pattern is complex enough and does not have big, horizontal, monotonic patches. A big area painted with monotonic color without change in hue and brightness does not lend itself to pixel shifting, as the result of the horizontal shift is identical to the original patch. The following depth map of a shark with smooth gradient produces a perfectly readable autostereogram, even though the 2D image contains small monotonic areas; the brain is able to recognize these small gaps and fill in the blanks ( illusory contours). While intelligible, repeated patterns are used instead of random dots, this type of autostereogram is still known by many as a Random Dot Autostereogram, because it is created using the same process.
