Analysis and marking of the reading saccades: determination of the saccade and of the fixation duration. ‘i’ and ‘p’ indicate respectively the beginning and the end of each saccade. We studied the post saccadic drift 80 ms and 160 ms after the end of the saccade, ‘x’ and ‘y’ indicate respectively these two periods of fixation. Lower blue trace: horizontal conjugate position. Upper orange trace: horizontal disconjugate position.
