New Optical Illusion

Submitted by: lauriloo 4 years ago in Weird




Scientists have discovered a new optical illusion that will screw up your brain big time. Focus on the red cross while the dots move. They are wriggling around, right? Wrong. All of them are moving "in straight trajectories and random directions without colliding."

In this paper, we report on a novel visual motion illusion. When hundreds of dots move in straight trajectories and random directions without colliding, the trajectories are perceived as wriggling rather than straight (bottom). We examined the nature of this "wriggling motion trajectory illusion" via six separate experiments. The illusion was most pronounced when there were a large number of dots (top). The illusion was independent of both the distance covered (Experiment 3) and the observer"s eye movements (Experiment 4) as well as the dot types (Experiment 5). We also showed that the proximity among the moving dots plays a role in the illusion (Experiment 6).

If you focus on one dot you will see it going on a straight line. But look at the cross and you will see the illusion of them wriggling around, trying avoid each other.





Stare at the cross. No, it"s not a screamer.

Naw, don`t see it. To me the entire field seems to have straight line trajectories.

Even tried to let my eyes go OOF like for a stereogram, but no wiggling perceived.

I agree the bad looping is distracting but I see the curves and randomness when I stare at the cross.

Had too much Touhou, I can still see them moving in a straight line.

@MechBFP and @uatme: I agree, the endless "jump" of the re-setting gif totally distracts me.

I see the dots as moving in groups though, does that count?

Not everyone sees the same thing.

The amount of distortion is relative to the individual. Different people have different sized areas de-focused/distortion.

I don`t have the fine dexterity of the person in Langer`s gif but, I don`t see wiggling, either.

Now dodge them.

I just don`t see the wiggling... in the corner of my eyes I see lots of dots all moving in straight lines. Maybe the amount of video game that require multiple points of focus I play ruined the effect for me?

They need to fix the animation so it doesn`t jump so hard when it repeats, hurts to watch.

Terrible. It would help if the GIF didn`t restart every 2 seconds.

I don`t see the dots going in a straight line because I am looking at the square. How can one be expected to know what something is doing when you are NOT looking at it?

And it`s a one-trick-pony. Once I knew they were in a straight line, that`s how my peripheral picked them up.
