    Blinks, saccades, and fixation pauses during vigilance task performance: I. Time on task (Tech. Rep. DOT-FAA-AM). Washington, DC: Office of . To test this hypothesis, we measured eye movement performance in pro- and anti-saccade tasks of ADHD and control participants ranging in age from 6 to 59 yr. In the pro-saccade task, participants were instructed to look from a central fixation point toward an eccentric visual target.

China Journal of Highway and Transport, , 28(6):   Amplitude threshold values for saccades and blinks are determined based on features in the recorded signal. The performance of the developed algorithm was tested by analyzing saccades and blinks recorded in two different conditions: a task where the eye movements were controlled (saccade task) and a task with free viewing (multitask).

    The accuracy of eye movement measurement heavily relies on a clear demarcation of the pupil and detection of corneal reflection. The visible spectrum is likely to generate uncontrolled reflections, while illuminating the eye with infrared light – which is not perceivable by the human eye – renders the demarcation of the pupil and the iris an easy task – while the light directly enters.

Pilots flew Sikorsky SC helicopters, under instrumental flight rules, for more than 2 h (ca. min). Eye movements were recorded before and after the flight with an eye tracker using a standard guided-saccade task. Afterwards, the second fixation task session was performed. Following the min rest break, the third and final fixation task session was performed.

During the rest break, participants went out to the courtyard of the faculty building together with the experimenter. The questionnaires were always completed after each fixation task. We propose the introduction of eye movement metrics, such as eye blinks and pupil dilation within the simulated LCT, assuming that eye movement metrics such as fixation number, fixation duration, saccadic amplitude, saccadic speed and gaze position would be obviously affected by the use of a IVIS while driving, because of the need to.

Scenario 1: eye movements during reading. Reading research is a popular field of eye-movement research, and has been so for long [].In this line of research, fixations may correspond to the period of uptake of visual information (in this case, text), and saccades are movements of the eyes that bring other parts of the text onto the most sensitive part of the retina for information uptake.

Changes in saccadic performance are strongly associated with dopaminergic modulation of the reward system, as shown in the human species 1 .Task 5: blink task Task. The participants fixated a central fixation target and were instructed to blink each time they heard a beep.

The Hz beep sound chimed ms for seven times with a pause of s between every beep. Each sound onset was uniformly jittered by ± s in order to make the onsets less predictable for the subjects.

We.Of the total 11 sets of data, the blink count, saccade count, pupil size, fixation duration, and fixation dispersion were analyzed through raw data.

The rest of the data were analyzed through saccade metrics. Then, finally, we performed planned t-tests to compare data between MW and attention.
