You know about saccadic eye movements?

Ha ha!

But, seriously, this is interesting.

First what it is. Then I’ll get to to why we’re  even talking about it. .

SACCADIC EYE MOVEMENTS

Your eyes are  strange. No offense. But they are. You wouldn’t think they would work as well as they do. There’s only one small part of  your retina where the vision receptors are close enough together to tell a bear from a bush. If our ancestors had tried to pick berries from bears, we wouldn’t be having this little talk,  now would we?

As the eye evolved,  it learned to keep the fovea, the aforementioned part,  on the move. The fovea follows a complex track around whatever you’re looking at, darting quickly over everything before steadying.  These quick eye  movements are automatic; you aren’t aware of them. To you, seeing the world seems  simple  and natural. Behind the scenes, the brain and the eyes are involved in a saccadic dance.

That’s how it works,  okay?

Back to my point.

DON’T YOU JUST HATE ALL THOSE PASSWORDS?

Well YOU might not have been aware of your eye movement but it’s nothing new to scientists and physicians. In Finland,  Dr.  Martti Juhola at the University of Tampere, wondered if saccadic eye motion could be used for identification (International Journal of Biometrics). He knew that these movement  patterns are unique for each individual. Could eye movements be used like passwords are used? Maybe instead of passwords?  Could we use a video camera to turn saccadic eye movements into a biometric ID that might – just might – free us from “password hell” someday? Just a video camera and the right software and we could lose the passwords? Wouldn’t that be nice?

Juhola ‘s group is developing a system for doing just that. If it proves viable,  maybe you will use it some day.

THE CATCH?

They’ve been trying to replace passwords with “biometrics” for years and years. It isn’t an easy thing to do get right. This Finnish idea might have legs but it will take time till we know.

    Why not just finger prints?

  2. MISTER Science Ain't So Bad

    Fingerprints have been an obvious contender to replace passwords. But so far the hardware/software combination needed to analyze fingerprints isn’t small and cheap and reliable enough for widespread use. It may also be possible to “spoof” some kinds of fingerprint readers, making it think you are someone else. There are rumors that the next IPhone will have a fingerprint reader. (There are also rumors that it will have a dung to gold converter.)
