Gaze-based technology has been around for years, but it
could on the shelves sooner than you might
imagine. A Danish firm, The Eye Tribe, has for about a year been trying to
develop mobile devices that people can control with their eyes.
“You have infrared light that is projected toward your
face,” Sune Alstrup Johansen, usability expert of the Gaze Group at the IT
University of Copenhagen, explained in a National Public Radio report.
“And the infrared light is then reflected in your pupil. And by seeing those
reflections we can pretty easily—well, not easily—with our algorithms, we can
easily calculate where you’re looking.”
The Eye Tribe has even created a variation on the
gaming app Fruit Ninja, in which the user slices flying fruit with his eyes instead
of a swipe of the touchscreen.
