GazeHawk (YC S10): On Accuracy

I'd like to know what goes into the loss in accuracy. At first you'd be willing to try to say the extra background, or the quality of the camera.<p>But after a little thinking I bet its more because of the unknown angle, possible variation in screen size, and where the user is sitting/the camera mount position.<p>Is it users that don't track well, or a combination of them and their hardware set up? If someone doesn't track well, does another person with a different eye color then sit down in the same position and track better?

70 pixels? that ought to be good enough to implement an optical alt-tab.<p>i would agree to arbitrarily invasive monitoring of my web activity in exchange for that.<p>details: special behavior for, say, the vestigial enter key to the right of the space bar on my old MBP. When it's depressed, trigger exposé and start tracking my point of fixation. As it's released, return from exposé with focus on the window i was looking at.<p>or maybe aapl would pay? it's got more wow factor than spotlight or time machine.

Just some information about the accuracy of our eye-tracking software - people have been curious, so I thought I'd share it with the community.<p>Feedback appreciated, as always!

I'm sorely tempted to become a customer of yours, one of these days, when I've found the energy to rework my site it will probably happen.
