OpenCV knows where you’re looking with eye tracking

Awesome, this is exactly the sort of thing I'm working on in my PhD. Glad to see it's becoming mainstream.

  really, what approach are you taking? I've written some stuff on eye tracking and have found basic methods like correlation work best

That's pretty cool. It's been a fantasy of mine to control the mouse cursor with my eyes.

  Imagine how annoying hover effects would be! New input modalities just can't be bolted on to existing UIs. That's why Windows tablets have always flopped and iOS looks nothing like Mac OS.
- therobot24 14y ago
  it's actually quite difficult because people have a tendency to look at the cursor rather than look past it...causing a never ending 'chase'

Now if this can just be incorporated into Dasher, I can finally get rid of these pesky hands.

Eye based window/input focus. I've been wanting this for years.

  Some things are so obvious it's worth wondering why we don't have them yet. I mean, multitouch is the best we can do?

    ob Hitch-Hikers quote For years radios had been operated by means of pressing buttons and turning dials; then as the technology became more sophisticated the controls were made touch-sensitive--you merely had to brush the panels with your fingers; now all you had to do was wave your hand in the general direction of the components and hope. It saved a lot of muscular expenditure, of course, but meant that you had to sit infuriatingly still if you wanted to keep listening to the same program.

  this would be super useful on mobile devices. zoom on focus

Have there been any studies on the effect of shining IR LEDs in such a close proximity into the eye?
- excuse-me 14y ago
  There is a large scale research project using a 10^30mW IR source - the study has been run on land animals for the last 500MYr

I did this as part of a class project last year with opencv. It's actually not too difficult: http://www.youtube.com/watch?v=XcEsDJA0CWE http://www.youtube.com/watch?v=XcEsDJA0CWE Edit: forgot to mention it was done with just a webcam...no fancy glasses
