Visual fatigue versus eye-movements

Visual discomfort under various brightness conditions using eye movements in watching stereoscopic 3D video

“…Note that all measurements are normalized by the maximum values for each measurement. Psychological studies have reported that more frequent eye blinking and reduction of pupil size refer to higher eyestrain [8][9][10][11][12][13]18]. Echoing the results of our subjective test, the eye-blinking rate in bright environments is higher than in dark environments.…”

“…Then, the visual comfort score for each frame was computed by a visual discomfort model that is constructed with subjective assessments only. Some eye movements are often related with visual discomfort in watching 3D video [8][9][10]. Lee et al [8] compared the amount of eyestrain between 2D and 3D using the frequency of eye blinking.…”

Investigation and modeling of visual fatigue caused by S3D content using eye-tracking

“…By using this method, saccades behavior was analyzed by Kim et al, who showed that saccades movement was decreasing with visual fatigue growing. In the study of Vienne et al, visual fatigue was evaluated as the vergence error, and was correlated to the used vergence efforts [34]. Moreover, works on visual attention revealed the difference in eye-movements during watching 2D and 3D content [35,36].…”

Investigation of visual fatigue/discomfort generated by S3D video using eye-tracking data

“…18 Another attempt to evaluate visual fatigue with characteristics of eye-movements was performed also by Vienne et al Their measuring of vergence error, blink rate and eye micro-movements revealed that the decreasing efficiency of the visual system can be seen as the outcome of visual stress as much as fatigue producing. 19 So far, most of studies aimed at finding a measurement which would accurately indicate the state of the visual system. Numerous visual characteristics that can be measured are used as indicators of visual fatigue, but none of them is precise enough.…”
