Light diffraction pattern reflecting off a human eye (IMAGE)
Caption
A pattern of distorted lines is visible as a reflection in this close-up view of a human eye. By observing the deformation of illumination patterns reflected off the eye's surface, researchers in Willomitzer's group can capture gaze direction information from tens of thousands of surface points instead of the dozen or so used by conventional eye-tracking methods.
