These aren’t far-off fantasies — they’re potential real-world uses of eye-tracking tech. And thanks to a new breakthrough at the University of Arizona, we may be a lot closer to all of it.

And as with any technology that tracks our behavior and biology, it also needs to be secure and privacy-conscious. That’s where this new research comes in.
