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

Edit: forgot to mention it was done with just a webcam...no fancy glasses
