Bizarre Illusion
A researcher from Japan has un-veiled a mind- bending new type of optical illusion.
At first glance, the 'Curvature Blindness Illusion' appears just an arrangement of wriggling and zig-zagging lines
crossing over white, grey, and black backgrounds.
But according to the creator, the image doesn't actually contain any zigzags - instead all of the lines have the same wavy shape.
In the illusion, the lines which have a dark segment running from the crest to the trough are those which appear to
be zigzagged on the grey background.
Those which have the dark segment at the crest itself - or the peak of the wave - maintained their curvy appearance
across the entire image.
But, Takahashi says all the lines are identical, with each made up of sine curves.
According to the researcher , this type of illusion may cause the brain to essentially go with what it knows best in
situations where it isn't entirely clear what it's seeing.
As the new optical illusion, revealed in a paper by psychologist Kohske Takahashi of Chukyo University, is made up
entirely of wavy lines, all with an identical sine curves.
When you look at it however, that's likely not what you'll see.
The white and black corners of the image show the lines as they truly are.
But, in the grey section, the wiggly lines suddenly become a jumble of alternating curves and zigzags.
'One must see the pairs of wavy lines (I.e gentle curves) and pairs of zigzagging lines (i.e, obtuse corners) on the grey
background,' Takahashi explains in a new paper on the illusion.
"Physically, however, all lines are wavy lines with an identical shape; there is no triangular wave and hence there is
no corner. One would find all the lines on the white and black background are wavy. As the effect magnitudes are quite strong, unless one carefully stares at the region that looks like a corner, it is hard to find that all the lines are
physically wavy."
