The influence of eye dominance on saccade
characteristics and slow presaccadic potentials.
When reading, it can be difficult for patients with ring scotomas to make smooth saccades
between words, to stay on the line, to find the next line of print, and to return back to the correct word or line if they lose their place.
Software generates fixation reports, including current, next and previous fixations, fixation count, and current, next and previous saccadic amplitude, angle, average velocity, direction, start, end, peak velocity, saccade
count, and saccade
A typical low-level visual effect on word skipping is the effect of launch site: the closer the eyes are to the parafoveal word, the higher the probability that this word will be skipped on the next saccade
(Kerr, 1992; Rayner et al., 1996; Vitu, O'Regan, Inhoff, & Topolski, 1995).
We conducted independent-sample t tests with the number of fixations, fixation duration, reading speed, saccade
lengths, and regressions as the dependent variables.
In the remaining patients, VNG (gaze, saccades
, optokinetic, and tracking tests) yielded normal results.
The vHIT system enables calculation of VOR gains and gain asymmetry (GA) and also detects corrective saccades
including overt or covert saccades
In this study, we evaluated the students' saccade
path (i.e., course of saccade
, COS) among the regions of interest (ROIs) such as the text paragraph, the picture area, the menu area, the logo, or the region outside of the webpage information area.
We classified eye-tracking variables as fixation, saccade
, or both according to the type of eye movement measured (Lai et al., 2013).
Some of the measures that could be obtained with this equipment were the number of fixations, the total fixation time, the number of saccades
, the total time in the trial, and qualitative analyses of ocular patterns, among several others.
is a rapid motion of the eye (typically lasting between 30 to 80 ms to complete) .
As mentioned in previous studies [19-22], saccade
intrusive components occur naturally during vergence even when a pure vergence movement is elicited.
