“The brain sends instructions to the eyes, the eyes respond with movement (called a saccade).”
“That can be attributed to something called a saccade—a fast movement of the eye that lasts between 20 and 200 milliseconds.”
“Nishigaki and Arai have turned to blind spot position and the so-called saccade response for their biometric.”
“In the 'saccade' condition while foveating one of the sample dots the horizontal separation between the dots corresponded directly with eccentricity.”
“For the 'saccade' (solid line with circles) condition, the eccentricity corresponded directly with the distance between the sample dots.”
“In 'saccade' trials a 200 ms blank gap was introduced in order to speed up a saccade toward the first presented dot”
“The left panel represents a 'saccade' trial when an observer foveates the leftward dot and at the same time encodes the rightward dot by peripheral vision.”
“The lower panels characterize neuronal populations responses to the visual stimuli in the 'saccade' (left) and the 'fixate' (right) conditions.”
“The difference in the eccentricity-related size of the RFs taxed by the 'saccade' (solid line with circles) and 'fixate' (dashed line with asterisks) conditions, results in a divergent pattern of distance estimation bias. doi: 10.1371/journal. pone.0009918.g005”
“In the second condition the observers executed saccades that brought the sample dots onto the fovea ( 'saccade' trials).”
