- This study investigated changes in behavioral performance before and after watching a multi-view 3D content
by using auditory stimuli based on the selective attention theory in order to quantitatively evaluate 3D visual
fatigue. Twenty-one undergraduates were asked to report on their current visual and physical condition both in
the pre- and post-experiment. A selective attention task was conducted before and after mobile 3D viewing to
compare the changes in performance. After performing a Wilcoxon’s matched-pairs signed-ranks test on the
subjective ratings of 3D visual fatigue, participants were categorized into two groups, unfatigued and fatigued
group with a definite criterion. For the unfatigued group, no significant fatigue effects were found in behavioral
response times and accuracies to specific auditory targets. In sharply contrast to the unfatigued group, the fatigued
group showed significantly delayed response times and less response accuracies. However, no significant changes
in accuracies for a working memory task were observed in both groups.
