ABSTRACT
Notwithstanding their widespread diffusion, stereoscopic media have important drawbacks in terms of viewers' visual discomfort. Current assessment methods are mainly based on measures of objective parameters such as eye physiology or media characteristics. On the other hand, subjective methods only evaluate the personal experience related to the physiological symptoms. In this pilot study we developed and validated the Stereoscopic Discomfort Scale (SDS), a self-assessment tool for the subjective evaluation of physiological and psychological symptoms related to stereoscopic viewing. The results show evidence of internal consistency, unidimensionality and construct validity of the scale. Since SDS scores were also strongly correlated with facets of presence, we argue that the SDS could be a useful tool for the investigation of users' experience related to stereoscopic media.

Reducing visual discomfort of 3D stereoscopic displays with gaze-contingent depth-of-field
SAP '14: Proceedings of the ACM Symposium on Applied PerceptionWe report on an experiment testing gaze-contingent depth-of-field (DOF) for the reduction of visual discomfort when viewing stereoscopic displays. Subjective results are compelling, showing, we believe for the first time, that gaze-contingent depth-of-...
Eye movements and visual discomfort when viewing stereoscopic 3D content
AbstractThe visual brain fuses the left and right images projected onto the two eyes from a stereoscopic 3D (S3D) display, perceives parallax, and rebuilds a sense of depth. In this process, the eyes adjust vergence and accommodation to adapt ...
Visual discomfort prediction on stereoscopic 3D images without explicit disparities
Almost all existing 3D visual discomfort prediction models are based, at least in part, on features that are extracted from computed disparity maps. These include such estimated quantities such as the maximum disparity, disparity range, disparity energy ...
