The article discusses the impact of vergence-accommodation conflicts on visual performance and fatigue, particularly in the context of 3D displays. The authors describe a novel 3D display that presents focus cues that are correct or nearly correct for the depicted scene, aiming to reduce perceptual distortions, fusion failures, and viewer fatigue. They find that when focus cues are accurate, the time required to identify stereoscopic stimuli is reduced, stereoscopy in time-limited tasks is increased, distortions in perceived depth are minimized, and viewer fatigue and discomfort are reduced. The study also explores the influence of focus cues on binocular fusion, space perception, and visual fatigue, and discusses the implications for vision research and display design. The authors conclude that minimizing the conflict between vergence and accommodation cues can significantly improve visual performance and reduce viewer discomfort.The article discusses the impact of vergence-accommodation conflicts on visual performance and fatigue, particularly in the context of 3D displays.
