Eye-tracking lenses

    James DiCarlo, professor of technology at the University of Massachusetts, has filed a patent for magnetic contact lenses. Such a thing is useful for tracking a person’s gaze and can be a very useful invention in many cases. Therefore, there is nothing strange in the fact that, primarily, the military from the US Naval Research Center became interested in DiCarlo's work.


    At the moment, systems that allow you to track the direction of a person’s gaze are available in the world. They are a camera and image recognition software. But such systems in a real situation turn out to be completely useless, since they can be knocked down simply by quick movements of the head. The system, proposed and patented by DiCarlo, consists of magnetic contact lenses and a special sensor that is mounted on the head. The sensor perceives the slightest changes in the magnetic field of contact lenses and, thus, determines the direction of view. The gaze tracking system should work regardless of lighting, head position, face shape or glasses.

    The scope of prospective development is quite extensive. First of all, of course, this is military needs. Lenses that track the gaze will be useful, for example, to the pilots of aircraft: pointing a missile at a target with just one look is very promising. But for "peaceful purposes" magnetic lenses can serve well. With their help, say, people with disabilities can drive wheelchairs.
