Document Summary
Computes the exact center of the pupil from this information: eyes travel in jumps called saccades of about 20 to 60 ms in duration, with intervals of around 200 to 250 ms when the eye is still, very little information is taken in while the eye is moving in a saccade: 15 characters to the right and only 2 4 to the left in english speakers, skilled readers may be able to take in more information in one fixation than less skilled readers, fovea is the most sensitive part of the visual field, and correspond to the central seven characters or so of average size text, fovea is surrounded by the parafovea where visual acuity is poorer; beyond this is the periphery, where visual acuity is even poorer, displayed text to readers with a moving mask that creates a moving blindspot: if the foveal region was masked, reading was possible from the parafoveal region but at a greatly reduced rate.
