"****FINAL CALL FOR ILLUSION SUBMISSIONS: THE WORLD'S 7TH ANNUAL BEST ILLUSION OF THE YEAR CONTEST****

http://illusioncontest.neuralcorrelate.com

The 2011 Best Illusion of the Year Contest will be held in Naples, Florida (Naples Philharmonic Center for the Arts, http://www.thephil.org/) on Monday, May 9th, 2011, as an official satellite of the Vision Sciences Society (VSS) conference. The Naples Philharmonic Center is an 8-minute walk from the main VSS headquarters hotel in Naples, and is thus central to the VSS conference.

Past contests have been highly successful in drawing public attention to vision research, with over ***FIVE MILLION*** website hits from viewers all over the world, as well as hundreds of international media stories. The First, Second and Third Prize winners at the 20019 contest were Koukichi Sugihara (Meiji Institute for Advanced Study of Mathematical Sciences, Japan), Bart Anderson (University of Sydney, Australia), and Jan Kremlacek (Charles University in Prague, Czech Republic)."

Which illusions do you think best help us inderstand the visual system?

Why do you think scientists woudl put on a contest for illusions?

Check out the parent site as well at (http://neuralcorrelate.com/) they are up to some cool stuff.

What would you do if you were a student in this lab?

"The car and motorcycle company worked with lighting manufacturer Profoto to produce a commercial with light effects that allow viewers to temporarily see the letters "BMW" when they close their eyes."

"The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level."

"The Best Visual illusion of the Year Contest is a celebration of the ingenuity and creativity of the world's premier visual illusion research community. Contestants from all around the world will submit novel visual illusions (unpublished, or published no earlier than 2009), and an international panel of judges will rate them and narrow them to the TOP TEN. At the Contest Gala in the Naples Philharmonic Center for the Arts, the top ten illusionists will present their creations and the attendees of the event (that means YOU!) will vote to pick the TOP THREE WINNERS!"

The two images below are widely available on the web but not attributed to any particular source. In the top image, do you perceive the balls as resting on the checkerboard in a diagonal line? But in the bottom image, as the three balls on the right floating, each a little higher than the one before?

Visual "illusions" aren't "tricks" but rather windows into how the brain makes informed guesses.

Most people assume that what you see is pretty much what your eye sees and reports to your brain. In fact, your brain adds very substantially to the report it gets from your eye, so that a lot of what you see is actually "made up" by the brain (see Seeing more than your eye does).

Welcome to Super Senses!

Our sense organs link us with the outside world.

They take in information and send it to the brain. Here it's deciphered and turned into something meaningful.

We communicate through our sense organs - touching, seeing, hearing, tasting and smelling.

Go to the site and then look at the two long lines.

Which one is longer? Try moving the two lines on top of each other. Try swapping the end pieces around.

What does this tell us about how the visual system attempts to resolve ambiguity? What are the gestalt principles? Which of these principles would describe what is going on here? Is this an example of a bi-stable illusion?

Interactive Demonstration:

The interactive display below can be used to acquire the ability to see Hofstadter's Road Sign in at least four different ways. Controls to the left allow one to bias one's perception by adding apparent barriers and arrows. Controls to the right allow one to vary the color of the dots at various locations in ways that may help one see different patterns.

Can you see the road sign in four different ways? If not, click here.

How many different ways are there to see the road sign?

Can you change how you see the road sign at will?

Which of the ways that you see the road sign is "real"?

Is the road sign "deceptive"?

What are the advantages of giving up a "reality"?

 

This is a nice illustration using real pieces to recreate a famous 2-dimensional illusion. This is a good site too.

I had to put this one up. This is a great example of how the visual system tries to resolve the retinal image. Is this a lamp or a woman in a bikini? How does the visual system try to resolve this? After giving it a try - check the answer by clicking on the continue reading link below.
