A bunch of UC San Diego researchers were studying exactly how many fixation points were necessary before a person recognized the face of the person they were looking at and found that they all looked at one point on the nose.
They showed experimental subjects a number of photographs of faces, and then had them try to recognize those faces, amid a crowd of new and unfamiliar ones, on a computer. The subjects were given a limited amount of time to remember each face. By varying that amount of time and tracking eye movement, researchers tried to pin down exactly how many steady looks (fixations) it took to recognize people.
Instead of staring at people's eyes, they stared at the center of the person's nose and if given time for a second fixation, most people would just glance to the left of the center of the person's nose.
