Fire in Your Eyes

[beamjockey]

My brother-in-law showed me his Amazon Fire phone, which features four cameras on the "selfie" side. This enables the phone to keep track of a user's eyes, for "Dynamic Perspective," a kind of 3-D display.

Later it occurred to me to wonder:

Are these cameras good enough to track the user's eye movements, and sell them to advertisers?

Yes, they certainly are. Basically if you can see the irises reasonably well in the image, it can track your gaze reasonably well. If you can make out the pupils, even better.

And this is why more kids these days know the definition of "dystopia" than know the definition of "utopia."

It hardly matters. If it doesn't today, it will in a couple of weeks.
One of my basic perspectives in industry watching is not looking for novelty but watching things slide down the price-performance curve. (Probably the biggest one lately is "soft" AI. Google gives smarter answers every day, and is steadily approaching natural language input.) There's a pretty obvious market for this capability, so it's just a matter of cost-benefit, with cost going ever down . . .

You didn't think they added that feature for the benefit of the users, did you?
