Laboratory for New Media 17th Exhibition
“Visual Illusion Lab in the Land of Mathematics”
Laboratory for New Media Permanent Exhibition periodically updates contents of exhibitions to introduce the various possibilities of expression provided by information science and technology.
Welcome to the Land of Mathematics. This is where mathematicians use new theorems and theories they have discovered to explain various natural and social phenomenon, and attempt to put these to practical uses in the real world. The two researchers featured here are engaged in the research of illusions caused by vision, or in short, visual illusions, using the method of mathematical modeling.
Lines and shapes do not appear to look the same as the way they were actually drawn. Patterns that should not have been visible can be seen. How do they confront a world of such irrational and strange visual illusions?
Visual Illusion Art Works (Hitoshi Arai, Shinobu Arai)
Through the creation and application of advanced mathematics for study about visual perception, it has become possible to engage in the research of elucidating the mechanisms of visual illusion. It is also becoming possible to take the research one step further, controlling the visual illusion and changing images that one likes into a visual illusion image.
Character String Tilt Illusion Generating Device (Hitoshi Arai, Shinobu Arai)
Around the year 2005, finding character strings that looked as if they were tilted became a popular game on Internet forums and other websites in Japan. Arai and Arai named this “character string tilt illusion,” and conducted research into the phenomenon. They created mathematical models of visual information processing in the brain, explored how character string tilt illusion is processed in the brain, and developed software that can automatically generate character string tilt illusions.
Impossible three-dimensional objects that play opposite a mirror (Kokichi Sugihara)
This exhibition showcases “impossible three-dimensional objects” that create phenomenon that are beyond comprehension when they are reflected in a mirror. These objects can be classified into three categories: “ambiguous three-dimensional objects” that appear to undergo dramatic changes when reflected in a mirror, “see-through three-dimensional objects” that appear to partially disappear when reflected in a mirror, and “topology-disturbing three-dimensional objects” that present changes of the ways of connection when reflected in a mirror.
Repulsive Slopes (Kokichi Sugihara)
If we were to look at it with just one eye from a specific viewpoint, a visual illusion of an “impossible motion” would occur—although the center point appears to be the lowest, a ball placed on an incline would move against gravity and jump out of the stand. This is a visual illusion that arises because we think that the inclines intersect at right angles when we look at them from a point directly above them.
