Not, as a child, sitting for long hours to make the tree dance with alternative blind eye? Keep some people’s fascination with visual magic, and the Best Visual Illusion of the Year Contest brings them together the result can change the way you see the world.
Competition is a wonderful coming together of science and art, and create a fun learning about optical illusions.
Visual illusions are perceptual experiences that do not match the physical reality. Understanding the visual illusion is an important part of the healing process in certain diseases of the visual system. Therefore – and this is a great job! – There is a visual scientists dedicated to discovering the basics of neural visual perception illusion.
Following the entry of former winners Best Visual Illusion Rob van Lier and Mark Vergeer (Netherlands), who is playing the illusion that suggests that induces visible color after color on fully diluted white. It is a known phenomenon, but what they show is that the color images can be produced to a different color then the image in the same location retina “‘(Lier & Vergeer). Click below and give it a try: Charge after picture after picture
What to do
Fix your gaze on the center of one of the characters, and look for some time (20-30 seconds) during rotation (without moving your eyes).
After a few iterations you begin to see that the blank lines fill with a reddish or semi-blue ghost. It is called “after-image”.
Interestingly, after a variety of color images, which is misleading because they are from the same original figure. In addition, the shape of the line in determining the full-color, color Compliment same shape in the original image.
Lier and Vergeer explained that the after-image perceived color depends on the contour of color images. But more specifically, illusion shows that the after-image colors spread and blend the contour.
“No phenomenon can cause the spread of picture elements after the physical appearance of the contours of the outline,” they said. “For example, when the circle is positioned in the middle of an outline form, with a picture then a felt board.
“In conclusion observation is due to the rapid spread of local patch-based after-image after image shown on the line.”
“Ghostly gaze” by Rob Jenkins: “you-think-he looks at you-but-it-all illusion,” illusion: Ghostly stare.
What to do
Move the slider and see how the two women with their eyes on you.
We usually try to find out by looking in the direction of a person think which side they are looking for dark eyes. Jenkins suggests that the details of such a line of IRIS reach a large patch of darkness.
We consider the social cues from the direction of gaze, and gaze illusion Ghostly Jenkins ‘shows’ gaze estimates are not always dominated by filthy distribution of light in the eye “. So make sure he really gives you a hint and you see before you act, guys!
U.S. Papathomas Thomas adding more famous illusions hollow mask illusion.
Did you ever have a mask hanging and is convinced that her scenes follow as you teach? Furthermore, when the hollow mask is made to rotate, it seems to change direction devoted to the fact that it is actually Spinning.
Now if we add things like nose ring, has not given a deep illusion mask there. Effect is to create the illusion of motion as objects appear to rotate in the direction with constant mask (you may need to download a program to see this picture): Hollow Mask
Building and clouds
Shaped skyscraper appear occasionally slip against the cloudy sky. Distortion of the parallel lines illusion disappear if the jagged contours.
However, the illusion Bettella, Casco Roncatos’, the illusion is still there, despite the jagged contours, because, “the visual system relies on a local lighting contrast local codes and position along the sloping contour bounded by a thin line. “

Here’s one for the artist. Dejan Todorovic, who won the third prize in 2005, featuring an impossible shaded arched. Our vision shading interpret differently, according to the shape of the contour.
In this image, two different shaded contour with the same pattern, but show two different remedy. It is shown how the optical system reacts when confronted with ambiguous input: Arch shaded
The illusion that Michael Pickard, Pinball Wizard, which causes a feeling of optical rotation. The interesting thing about this famous illusion that it violates the “rules”.
While classic Rubin vase illusions show how we automatically separate foreground and background images, Pinball Wizard displays a picture performs as well as two pictures.
This gives rise to a sense of illusion of rotation. Using visual cues to create the impression of depth and carefully selected color values, combined with a static screen animated ball horizontal traverse.
