Ghostly Gaze Illusion by Rob Jenkins

Best Visual Illusion of The Year contest is something we’ve been covering for two years in a row. Top 10 submissions of 2008 can be found on the Contest homepage. While this illusion hasn’t made it close to top 3, its surely my favorite this year. Here is the explanation: how do we tell where other people are looking at? Conventional wisdom says the dark parts of their eyes give it away. The Ghostly Gaze optical illusion reveals a more subtle process – from a distance, the two sisters seem to stare at each other. But wait! Using the flash zooming slider, if you bring them closer, they turn their eyes to you! This is not a computer trick.

To convince yourself, set the slider to “Close” and walk away from your computer screen while looking at the image. Notice that when you are sitting in front of the monitor, the sisters are looking at you, but when you are about 3 meters away, they look at each other! The illusion is based on the hybrid image technique, developed by Schyns and Oliva. The Ghostly Gaze illusion shows that details such as the outline of the iris can override larger patches of darkness. Which section should I add this article to? I was thinking of “Multiple Meanings” or “Animations”, but am not exactly sure? To check some of the best optical illusions from 2007 (I don’t share the same opinion), visit this article.

  1. Thanks for getting rid of that damn animated gif file. I hate it when those show up on my Google home-page.

    As far as this one goes, not much of an illusion. Anyone who has worn glasses or contacts could probably tell you that small shadows in the distance can be misleading.

    Still – thanks for replacing that gif file. Every time animated gifs show up, I’m another step close to deleting this add-in.

  2. hi im bryan i love this site ive been coming to this sight for along time anyways thats a really cool illusion hope to see more

  3. its only because there is a dark shading in the corners that their eyes “travel” to and you cant see the clear eye far away.

  4. Oh, wow! That is so cool! I love it!
    When I look at them individually, their eyes don’t seem to move, but when I look at both of them a the same time, from farther away, they’re looking at me, and then when I zoom them in, their eyes turn to me! Freaky…

  5. it only works because the girls eyes are a very pale blue. The blue eyes blend in with the white part of the eye at a distance and the shadow becomes a brown colored pupil. Amazing effect though.

  6. with the picture of the sister at the top of the post, i got the impression they were both looking outwards and not towards each other at all.

    but the slider did work :)

  7. Cool but a little freaky.
    İ think the optical illusion is caused from the black parts, witch make the sisters stare at each other.
    The secret is reveled when you come closer..

    Awesome!

  8. woah, like, thats weird, it made my dad freak out o.O but it didnt scare me, i jus’ shiverd , hehe.

  9. IT’S A HOAX. Sorry…

    Try this to prove the hoax:

    Zoom out until the faces look small and looking at eachother. Copy your computer display to the clipboard (just push the “hard to find” “Print Screen”, or “Prt Scrn” Key.)

    Open the Paint application and paste the image. Then do the zoom yourself. You will see that no mater how big the faces get, they will still be looking at eachother.

  10. if u stare closely at the eye balls you can see they don’t move. But if you’re just looking at the image, it appears that the eyes are moving. COOL! :)

  11. If you look ot them close then keep watching one it seems that she is still staring at you. If you now look to the other one she is staring at the other lady. Now look back at the other one and you will se that she turned her “ghostly gaze” to her “sister”.

  12. The “tricks” points at the “dark shade” they put on the “corner side” of the eyeball of the girl on the second/right picture . They changed the position of it, compared to the eyeball of the girl in the first/left picture.

    As you can see both pictures are the same, Why? because, the light that falls on their face, is positioned/coming from “their right side” thus the dark shadow of their nose falls both on their left cheeks.

    Only the 2nd picture on the right has been “touched/photo shopped?”. How? Try this, Put the blue dot of the slider into the “close” level, their highest zoom.

    Then, right click the picture and “zoom in” it, once or twice. Hold and drag/move it sideways left and right. Observe the differences of their eyeballs “shade” on both pictures, particularly on its “side corner”.

    The “right side corner” of both eyeball of the girl in the first picture have a “lighter shade” because of the light that falls on it.

    On the contrary, the “right side corner” of both eyeball of the girl in the second picture have “darker shade, hence, the “trick”

    That’s what make the “illusion”, you just can’t tell the difference until you studied it carefully.

  13. This looks even better if you cross your eyes while the pic is zoomed in. Her eyes are amazing in stereovision. Now that is an awesome illusion.
