"Eye-tracking, which uses images from one or more cameras to capture changes in the movements and structure of our eyes, can measure all of these things with pinpoint accuracy. There are many benevolent applications for eye-tracking, most notably in providing disabled people with a way to interact with objects on a screen. But recent advances are taking the technology into the mainstream, with the biggest initial applications likely to be in user interfaces and gaming. Apple, for example, has filed a patent application for a three-dimensional, eye-tracking user interface, and European company Sensye aims to have its eye-tracking software built into smartphones next year. As eye-tracking becomes increasingly deployed in laptops, tablets, and smartphones in the coming years, it will open a new front in the fractious digital privacy debate."
