Cool illusion

#1  Postby Macdoc » Sep 13, 2016 2:04 am

Look at this image. You will see black dots pop up at various intersections. You might see a few of them at once. You will almost certainly not see all 12 at once, thanks to our eyes being relatively bad at peripheral vision, thanks to a phenomenon called lateral inhibition. Instead, you'll see the dot in the center of your vision, along with some of the adjacent dots.

If you can see all 12 dots at once, you should go ahead and put that on your resumé.

If you gently scroll the image up and down, the dots will appear. It is related to our peripheral viewing. Introduce motion and our peripheral scanning kicks in properly, wheras it doesn't work when stationary half as well.
The Bible is full of interest. It has noble poetry in it; and some clever fables; and some blood-drenched history; and some good morals; and a wealth of obscenity; and upwards of a thousand lies.

It's a has a huge influence on our driving ability ...as you cannot rely on peripheral vision to pick out other vehicles especially motorcycles....you actually have to swivel and look at them .
If the vehicle is moving in relation to you then your eyes will pick it out....stationary ....it's gone.

It's because the dots don't exist until you observe them... I'll get me coat. :shifty:

Being pedantic; more a cool demonstration of our vision's limitations than an illusion.

True but there are elements of an illusion as the dots appear and disappear at random despite all being there.
