Magic eye images - autostereogram

[Chiefsmom]

WHile I can find the "spot the difference" images usually very quickly, I cannot for the life of me, see anything in these images.

I gave up, because I got frustrated.

I will try Encia's method.

Nope, still nothing, no matter the method.

the shark one is divergent perspective... meaning you have to look somewhat behind the image to get the stereo field to resolve correctly. i find these trickier to do than the cross-your-eyes ones (convergent perspective). so, using the pen trick, you would have to hold the pen behind the screen, not in front.

the spot-the-difference puzzles are really easy if you cross your eyes and make the two images overlap. then you look for shadowy areas that are visible to one eye but not the other -- those are the differences. it's also useful to help train your eye to separate focusing from converging/diverging, as you need to focus like it's at one distance but converge like it's at another.

Can you see these? I can not, been frustrating me for the last couple of decades.

I'm tempted to say the magic eye game was invented by a mischievous artist who said we should troll the public for the next 50 years by publishing a catalogue of colorful images resembling TV static and pretending there's a picture hidden inside, but there is no picture.



The truth is...

The autostereogram was first conceived by Christopher Tyler in the 1970s. Using computers, he was able to combine the different visual theories to generate the first random dot stereogram that allowed the brain to perceive 3D from a single 2D image without any optical help.

An early version of what we now know as Magic Eye images started in 1959 by neurologist and psychologist Bela Julesz as a test to analyze people’s ability to see in 3D. Many years later, a student of Julesz, Chris Tyler, and a computer programmer, Maureen Clarke researched what was happening between the eyes and brain when people looked at stereograms.

It's important to note that some people will unfortunately never be able to see stereograms. These are usually people who have binocular or stereo vision impairments such as deviations or misalignments in one or both eyes, astigmatism, or cataracts.

Yes. It is a rectangle filled with various colour dots.

Just kidding. The same technique makes, for example, spotting the seven differences between these two images quite easy:

Back in 1993 there was a website that was called 3d Solar System, or something similar .
It had two images on the screen, both of the solar system, though slightly different. If you brought them into focus as the above post, the solar system would appear in 3d! It was awesome!
