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.

This is a still picture, but it looks as if the UFOs are moving.

Sugihara calls it an “anomalous mirror symmetry” in a scientific paper. The shape is affected by okkichi viewing angle. 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.

In a scientific paper he writes, “I coined the term ‘impossible motion’ to label a new type of optical illusion in which viewers perceive objects that appear to move in physically impossible patterns.

The arrow is always right. Others can be downloaded from the Internet, but require a 3D printer. The Neural Correlate Society has voted in its picks for the best new illusions that highlight interesting things about perceptionCNET.



Concepts and Applications of Voronoi Diagrams Wiley, ; 2nd ed. This picture was created based on a mathematical model of the human visual perception process. 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 When we see it with one eye from the specific viewpoint, we perceive an object consisting of a vertical column and four perches skgihara horizontally by mutually right angles.

Line Dance of UFOs.

The secret is in the shape of the object, which is only revealed fully when the viewing angle is modified. Only when it is rotated the eye correctly interprets the size of the central pillar, which is shorter than it seems.

One such example, a winner of Best Illusion of the Year, is called “Magnet-like slopes. The explanation lies, once again, in the perspective: Retrieved from ” https: I also feel that mathematics has the power to create what has never existed. Turner Broadcasting System, Inc. His illusion “Ambiguous cylinder” has the professor moving a series of objects, which he has 3D printed, in front of a mirror.


The psychology of ‘organization porn’. This is your brain on tidiness: Bewilderingly, even when spun around degrees, the arrow still points to the right.

But not with this one, Sugihara notes: The two penetrating plates align sugigara at the left but vertically at the right, giving the impression of an impossible object.
