SUGIHARA Kokichi. Professor, Dr. of Engineering (to my Japanese homepage). My illusion ” Ambiguous Garage Roof”. The roof of a garage and its mirror image . Taken from a Japanese toy set inspired by Sugihara’s mathematical explorations, it looks to be a optical illusion arrow kokichi sugihara x. Kokichi Sugihara is a Japanese mathematician, professor, and artist who specializes in 3D printing “impossible objects” to create.

The mathematical structure of this tiling pattern is the same as Escher’s artwork, sufihara and Water I” This type of incredulous reaction leaves Sugihara amused rather than frustrated. Turner Broadcasting System, Inc.

Home Exhibitions Log In. His interest in illusions stems from his research in the s on automating the analysis of perspective drawings, [2] [11] which he published in the MIT Press book Machine Interpretation of Line Drawings.

This page was last edited on 14 Novemberat This shape was created by a system of equations for reconstructing three-dimensional objects from a two-dimensional picture. Views Read Edit View history. But not with this one, Sugihara notes: Sugihara earned bachelor’s, master’s, and doctoral degrees in mathematical engineering from the University of Tokyo in, and sugihqra.

In this sense, this illusion is strong and robust,” he said.

This is a still picture, but it looks as if the UFOs are moving. When we see it with one eye from the specific viewpoint, we perceive an object consisting of a vertical column and four perches extending horizontally by mutually right angles.



The bee at the top deforms gradually downward, melting away into the background, and another shape appears from the background and becomes the clear shape of a stag beetle at the bottom.

Sugihara calls it an “anomalous mirror symmetry” in a scientific paper. Seen from above, the object looks like a hybrid between a square and a circle, or a square with very rounded corners.

Optical illusions that offer an impossible motion eventually tend to nudge the brain into correcting the visual interpretation of the object, and once that happens the illusion is lost. Kokichi Sugihara specializes in the impossible. Concepts and Applications of Voronoi Diagrams Wiley, ; 2nd ed. Actually, when we move our eyes horizontally, the UFOs move vertically, and when we move our eyes vertically, the UFOs move horizontally.

Sugihara, a kokicji engineer at Meiji University in Japan, has published several studies based off his creations and he’s also twice won the award for Best Illusion of the Year. Sugigara psychology of ‘organization porn’. The secret is in the shape of the object, which is only revealed fully when the viewing angle is modified.

One such example, a winner of Best Illusion of the Sugiihara, is called “Magnet-like slopes. He won first prize in the Best Illusion of kkkichi Year contest twice. Kokichi Sugihara is a professor of mathematical engineering at Meiji University. Sugihara’s research also includes the study of Voronoi diagrams. Generated by my computer program.

Since he has been a professor at Meiji University. Others can be downloaded from the Internet, but require a 3D printer. Kokichi Sugihara’s ‘impossible’ objects. The Neural Correlate Society has voted in its picks for the best new illusions that highlight interesting things about perceptionCNET. From to he worked as a researcher at the Ministry of International Trade and Industry.


Bee and Stag Beetle. A mathematician is using computers to manufacture award-winning illusions”Nautilis. By using this site, you agree to the Terms of Use and Privacy Policy. I gave the top bee and the bottom stag beetle to my computer program, kokici the program generated the intermediate tiles and their placements. This is an example of figure-ground reversal tiling art.

Bewilderingly, even when spun around degrees, the arrow still points to the right. Sugihara’s ambiguous objects are a mathematical work of art that uses the physics of optics to show us how our senses and perceptions can be fooled, and yet we can fully understand how the phenomena works,” said in an email Ray Halla professor of physics at California State University, who made the video above using a Japanese toy set which includes objects derived from Sugihara’s studies.

Perhaps the most astonishing of his impossible objects is a simple white arrow pointing to the right. The marbles roll uphill! How is that possible?
