Yet, the split-up effect is unnoticeable when the light field is viewed directly through a human eye. In this paper, we attribute the unobservability of the split-up effect to the decrease in visual acuity as a function of retinal eccentricity and to the low-pass filtering property of visual attention. Theoretical and experimental results are provided to support our claim. Furthermore, we set an observability criterion for the split-up effect and discuss design strategies for performance improvement of light field displays.augmented reality | Communication hardware | Computer graphics | Computing methodologies | Graphics systems and interfaces | Hardware | Interfaces and storage | Light field display | Mixed/augmented reality | Perception | retinal eccentricity | split-up effect | visual perception[SDGs]SDG3conference paper10.1109/ISMAR59233.2023.000322-s2.0-85180365386https://api.elsevier.com/content/abstract/scopus_id/85180365386
