Visual discomfort and chromatic flickers [PDF]
Vision ResearchFlickering patterns that shift in chromaticity can be uncomfortable and may trigger epileptic seizures, though the underlying factors are not fully understood. In the spatial domain, chromatic contrast in images is a potential predictor of visual discomfort, with higher contrast generally leading to increased discomfort. This study investigated whether

Investigating visual discomfort with 3D displays
CHI '13 Extended Abstracts on Human Factors in Computing Systems, 2013Notwithstanding 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.

Visual Cognition, 1999
A two-parameter Rasch Rating Scale model was developed to measure visual discomfort. Initially it was found that participants reporting frequent severe headache, reading difficulties of a visual nature, and short effective reading times experienced more severe visual discomfort. The validity of this measurement instrument was tested in four experiments.

Lighting Research & Technology, 2018
Visual discomfort refers to discomfort or pain in or around the eyes, often associated with headache and/or nausea, and sometimes accompanied by signs such as red, itchy or watering eyes. The lighting conditions likely to cause visual discomfort are insufficient light for the task at hand, dramatic differences in illuminance around the task, shadows ...

Visual discomfort in stereoscopic displays: a review
SPIE Proceedings, 2007Visual discomfort has been the subject of considerable research in relation to stereoscopic and autostereoscopic displays, but remains an ambiguous concept used to denote a variety of subjective symptoms potentially related to different underlying processes.

Visual discomfort in the classroom
Child Language Teaching and Therapy, 1991Treatment of reading difficulties with coloured overlays and Irlen filters is reviewed. The accumulated anecdotal evidence for beneficial effects in certain children can no longer be ignored, but scientific evidence is lacking. Advice for the classroom management of visual discomfort and associated perceptual distortion is offered.

Migraine and Stripe-Induced Visual Discomfort
Archives of Neurology, 1989We investigated stripe-induced visual discomfort and its relation to migraine. Some people find viewing striped patterns aversive. Prior work has suggested that migraineurs, in particular, are bothered by stripes. Subjects were selected by opportunity sampling.

Effect of absence on visual perception and discomfort
IVMSP 2013, 2013Prior researches on binocular mismatches of stereoscopic images mostly focus on optical errors (magnification, shift, rotation, distortion) and photometric asymmetries (color, luminance, definition). In this paper, a type of binocular mismatches - effect of absence is investigated to find whether the partial loss of an object in either one of a stereo ...

Visual Discomfort: The Influence of Spatial Frequency
Perception, 2001The response of different visual discomfort groups to a range of spatial frequencies at threshold and suprathreshold was investigated. In experiment 1, a paired-comparison task was conducted. The high visual discomfort group judged a spatial frequency of 4 cycles deg−1 as the most perceptually distorted and somatically unpleasant to view. The moderate

Trends in Neurosciences, 1986
Abstract The pattern in Fig. 1 can provoke anomalous visual effects: illusions of colour, shape and motion. People differ considerably in their susceptibility to these effects and some find the pattern unpleasant to look at. Readers who suffer from migraine or epilepsy are advised not to look at the pattern because it might bring on an attack.
