Abstract
Developing a valid measurement of visual fatigue induced by 3D display remains a big challenge and is beneficial for optimizing the system design. In this paper, effects of 3D visual fatigue on the dynamics of saccadic eye movements are examined. Thirteen subjects participate in a random dot stereogram (RDS) based task, the performing of the task by the subjects is assumed to directly influence the level of visual fatigue that is evaluated using subjective ratings, optometric tests and eye movement indices. The results of critical fusion frequency (CFF) and accommodation measurement (ACC) show that the proposed experiment setup can induce visual fatigue. According to the subjective ratings, the visual fatigue accumulated in the experiment is mostly related to the binocular vision stress of 3D display. The peak velocity‐magnitude relationship of saccadic eye movements decreases after the experiment, and no significant differences are observed in the other saccadic parameters. Our conclusion is that saccadic eye movement, particularly the peak velocity‐magnitude relationship, is a sensitive indicator for visual fatigue caused by 3D display and has the potential to help the establishment of a valid on‐line measure for the detection of 3D visual fatigue.
