Early Life Before Joining Danganronpa Kokichi Oma was a normal talentless high school boy who participated in the 53rd Season of Danganronpa , a famous worldwide reality show made by Team Danganronpa. However, it is unclear if this memory of him was a part of the fabrication made by Team Danganronpa or if it was genuine. They have traveled around the world and commit "laughable crimes" for fun, which could indicate that they could be a group of orphans with no families nor parents to hold them back. Kokichi is also good at stealing, which might be due to his past, and it has been pointed out that many of his skills have a resemblance to a petty thief. Furthermore, his organization could be a reference to the animated television series D. DNA Integrated Cybernetic Enterprises , which is about an organization run by children, specifically orphans.

My desire was to allow a computer, by processing information input, to understand a 3D shape based on a projection drawn with lines. This field is now called computer vision or pattern recognition. A computer often fails to reconstruct a 3D shape from a projection drawing and delivers error messages, while humans can do this task very easily. For example, people can recognize a projection of figure 1 as a truncated triangular pyramid. This example indicates why this field is so difficult.

In this projection, the hand-made red lines which are supposed to correspond to edges of a truncated triangular pyramid and meet precisely at endpoints are subtly off the dash lines.

Unexpectedly, the software reconstructed solids that we never could imagine are possible through human eyes. We visualize a 3D object from a 2D drawing based on the preconceived assumption that is obtained through common sense and visual experience. However, the computer is not influenced by any assumption. If we could reveal how and under what conditions human visual illusions occur, we would be able to numerically express the strength of visual illusions and control the quantity.

The numerical system of the human illusion, studied further and consequently applied to practical situations, might be helpful in reducing traffic congestion on freeways. It has been made clear that road design is strongly associated with the occurrence of visual illusions. Traffic congestion recurring in places where there is no specific reason for congestion—no incidence of road accidents or no merging roads—is actually caused by the visual illusions of drivers.

While driving, drivers are sometimes confused about whether they are going uphill or downhill. Drivers who are expected to accelerate going uphill misunderstand the terrain that they are on due to the visual illusion, and slow down instead.

As a result, traffic congestion occurs. Conversely, we might produce conspicuous road signs, alarming drivers by applying the mechanism of visual illusion. It is possible that we will do public relations more efficiently or create more effective commercial messages by applying visual illusion. In virtual reality, by inducing visual illusions, we can experience realistic sensations of what is imaginary.

As mentioned above, the effects of visual illusions have a strong affinity with the entertainment world, and therefore, I believe that computational illusions have great potential as tools in the entertainment business. Engineering geometry is applicable to everything that has form Differences emerge between human perception and mathematical analysis.

Engineering geometry involves probing these differences closely in order to find out how humans analyze a phenomenon and employ solutions for the welfare of society. The field is probably useful for any type of industry. For example, engineering geometry could provide information regarding which location for a new hospital is most convenient for members of a community.

A formula used in a computer simulates physics experiments for production of spatial discretization in geometry. Moreover, geometry optimizes logistics management in the network. There are many ways in which the study of geometry in relation to anything that has form can contribute to our society. I regard geometry as a truly flexible set of measures and continue to encourage students to maximize their ability to use it to do great work in various fields.

Profile Dr. He previously taught mathematical engineering as a full professor at the graduate school of the University of Tokyo for nearly two decades from to Also, he was a visiting associate professor at Purdue University in West Lafayette, Indiana from to His research includes work with Voronoi diagrams and their applications, robust implementation of geometric algorithms, mathematics in visual perception, computer vision and computer graphics, and mesh generation for the finite element method.

He has written many books, including textbooks and collections of essays on mathematics. Sugihara, while researching mathematical applications of engineering science, has been introducing impossible solids and motions as shown on YouTube and production based on tricking human optical perception.

Miroir déformant ou illusion ?

My illusion " Ambiguous Garage Roof " The roof of a garage and its mirror image appear to be quite different. The human brain likes to interpret the edge of the roof as a planar cut perpendicular to the axis of the roof, but actually Visit here for the "Ambiguous Objects" and construction kit for the garage roof. So I decided to start this series of lectures on 3D optical illusion with the hope that they could entertain those who stay home. This is my way of fighting against the new coronavirus.
