Eye Jitter ( An Optical Illusions)

  The phe­nom­ena on this page rely on your eye move­ments. You will be mov­ing them any­way (you can never keep your eyes re­ally still), but the demon­stra­tions are aided by mov­ing your dis­play (if pos­si­ble), or by scrolling the page in small steps.

The first sam­ple on the right called “Ouchi Il­lu­sion”. When you shake your head rapidly, or bet­ter shake the dis­play, a cen­tral disk will seg­re­gate as a dis­tinct ob­ject, which in ad­di­tion seems to be float­ing top the back­ground.

This image on the left is called “Out of Focus”. It also leads to a seem­ing shift of the cen­tral disk with re­spect to the sur­round. It is very ef­fec­tively pro­voked by the eye move­ments oc­cur­ring dur­ing read­ing. So, while you are read­ing this cast your “inner eye” to the left and watch for a seem­ing de­cou­pling of disk and back­ground. You may also ob­serve that the disk floats above the back­ground. (Image re­pro­duced with kind per­mis­sion.)

This sam­ple called “Float­ing Mo­tion”.  We needn't to shake the screen, or the sac­cades from read­ing, just by ex­ploratory eye move­ments over the image the cen­tre square “de­cou­ples”. Here the back­ground seems to move, while the cen­tral square re­mains in place, and seems to float on top. 

It's easy to practise optical illusion, right? 

You can find them and make a different thing to every picture.. 

This needn't a tool or aplication.. Even you can make it by yourselves.. 

This is a simple thing when you think it's not difficult..

In other post, I want to discussed about optic illusions and the figure of illusionist.

So, check it out.. =D

God Bless You.. ^^
