This optical illusion of floor tiles can easily knock you out
Optical illusion (visual illusion) is a mistake in visual perception caused by inaccuracy or inadequacy of the processes of the unconscious correction of the visual image (lunar illusion, incorrect estimation of the length of segments, the angles or color of the depicted object, illusion of motion, "illusion of the absence of the object" - banner blindness, etc. .), as well as physical causes ("flattened moon", "broken spoon" in a glass of water). The causes of optical illusions are investigated both in the analysis of the physiology of vision and in the study of the psychology of visual perception.
In artistic images, the intentional distortion of perspective causes special effects, best known from the works of Maurice Escher (see, for example, his lithographs: "Up and Down" (1947), "Convex and Concave" (1955), "Belvedere" (1958) etc. The creation of optical illusions was often the theme of Salvador Dali's works (see, for example, his paintings The Slave Market with the Appearance of the Invisible Bust of Voltaire (1938), The Swans Reflected in Elephants (1937), etc. ) Some optical illusions were studied within the framework of Gestalt psychology (eg, Akiyoshi Kitaoka).
One of the things that give confidence in life is the feeling of a solid ground underfoot. But for some reason the company responsible for this sex wants to save you from this feeling, forcing the brain not to believe what the legs feel.
The entrance to the Casa Ceramica ceramic tile in Manchester, England, looks like a funnel or a gravity well!
But, in truth, in fact, this floor is flat and you just see the optical illusion created by the tile.
And it's easy to see if you still get to the other end of the corridor and look back!
Illusions often lead to completely incorrect quantitative estimates of real geometric quantities. It turns out that you can make a mistake of 25% or more if the eye measurements are not checked by a ruler.
Eye measurements of geometric real quantities depend very much on the background image. This refers to the lengths (Ponzo's illusion), areas, radii of curvature. It can also be shown that what has been said is also true with respect to angles, shapes, and so on.
You can even view a short video about how the tiler laid this floor. Of course, this will completely destroy the illusion in your head, but it is still interesting.
Duncan Cook, director of Casa Ceramica, shared a video on Twitter to show how they created this effect. The tiles were laid in a curved pattern, which can be seen under an alternate angle.
