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.

Sugihara creates his objects as part of his academic research. Since he has been a professor at Meiji University. A mathematician is using computers to manufacture award-winning illusions”Nautilis. Home Exhibitions Log In. Sugihara, a mathematical 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.

The explanation lies, once again, in the perspective: Kokichi Sugihara’s ‘impossible’ objects.

Bee and Stag Beetle. The red square ring passes behind the vertical column, but at the same time passes in front of all the four horizontal perches; thus it generates the illusion of an impossible object.

The mathematical structure of this tiling pattern is the same as Escher’s artwork, “Sky and Water I” Line Dance of UFOs.

He then became an associate professor in the Department of Information and Computer Engineering at Nagoya University inand moved back to the Department of Mathematical Engineering and Information Physics at the University of Tokyo in Bewilderingly, even when spun around degrees, the arrow still points to the right.


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. I also feel that mathematics has the power to create what has never existed.

I introduced a mathematical approach to this topic, and thus can create new types of 3D optical illusions,” he explained in an email interview.

The two penetrating plates align horizontally at the left but vertically at the right, giving the impression of an impossible object. Perhaps the most astonishing of his impossible objects is a simple white arrow pointing to the right.

In this sense, this illusion is strong and robust,” he said. Only when it is rotated the eye correctly interprets the size of the central pillar, which is shorter than it seems. The marbles roll kookichi

How is that possible? Eccentric Ring Toss 2. With three co-authors, he wrote Spatial Tessellations: The psychology of ‘organization porn’. From to he worked as a researcher at the Ministry of International Trade and Industry. Turner Broadcasting System, Kokichii.


Some of Sugihara’s illusions are meant to be seen in motion. 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.


This is an example of figure-ground reversal tiling art. 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.

One of his research areas is computational approaches to visual illusions. Professor of Mathematical Engineering.

This picture was created based on a mathematical model of the human visual perception process. Others can be downloaded from the Internet, but require a 3D printer. Seen from above, the object kokivhi like a hybrid between a square and a circle, or a square with very rounded corners.

From Wikipedia, the free encyclopedia.


Sugihara’s research also includes the study of Voronoi diagrams. Sugihara earned bachelor’s, master’s, and doctoral degrees in mathematical engineering from the University of Tokyo in, and respectively. The Neural Correlate Society has voted in its picks for the best new illusions that highlight interesting things about perceptionCNET.
