Visual Discomfort and Visual Function: Colour and Contrast
In six studies, vision and visual discomfort were investigated in individuals who experienced migraine or reading difficulty. Contrast discrimination thresholds were measured at two pedestal contrasts (10% and 50%) in volunteers with migraine with aura (MA), without aura (MO) and controls (C).There …

Validated interactive daylighting analysis for architectural design
… approach to predicting interior illumination and visual discomfort in buildings is to run a ray tracing simulation with high accuracy settings, wait while the simulation processes, and repeat as necessary with modifications to the scene and settings. This workflow lacks interactivity and usually …

The use of visual comfort metrics in the design of daylit spaces
… or intense reflections from daylight can cause visual discomfort or the inability to perform tasks. Typically, the total amount of luminous flux incident upon a surface per unit area - illuminance - present is used to predict visual discomfort due to questions about the benefit and validity of …

Effects of illuminance, luminance, viewing angle, and screen test pattern on the perception of flicker in CRT displays
… more widespread, the number of complaints of visual discomfort and eye strain among computer operators has also increased. The temporal flicker of display screens can be a significant source of this visual discomfort. The purpose of this research was to determine how illuminance, luminance, …

Discomfort glare, light scatter, and scene structure
… visibility is a measure of how far above the visual threshold a task's contrast is). Stiles distinguished disability glare, a light scatter effect, from discomfort glare which was glare that could not be attributed to light scatter. The distinction made by Stiles resulted in the separate …

The effects of stereoscopic 3D on an incidence response training game
… critical, and the inability to do so may create visual discomfort or an unnoticeable S3D effect.

Impact of macular pigment optical density on photophobia threshold
… light, MP may attenuate photophobia (PP)---visual discomfort induced by normal light exposure---for targets composed of short-wavelength light. The aim of this study was twofold: first, to investigate a possible relationship between integrated macular pigment optical density (MPOD) and PP …

Towards Passing Visual Turing Test with Computational 3D Displays and Appearance Modeling
… Facebook) defined a grand challenge termed visual Turing test in 2022, asking if the virtual experience can be created as vivid and realistic as the real-world such that a human observer can no longer distinguish. Passing this test requires significant technological advancements in areas …

Exploring 3D User Interface Technologies for Improving the Gaming Experience
… to enhance depth discrimination and minimize visual discomfort, the game dynamically optimizes stereoscopic 3D parameters (convergence and separation) based on the user's look direction. We conducted a within subjects experiment where we examined performance data and self-reported data on …

Display Technology and Ambient Illumination Influences on Visual Fatigue at VDT Workstations
The concept of "visual fatigue" has been studied for 70 years or more. In that time, no single metric of measuring visual fatigue nor one agreed-upon set of tasks to induce visual fatigue has been settled upon. Not even a robust definition of visual fatigue has been established. This research …

Qualitative and quantitative optimization of skylights : a comprehensive and inclusive analysis of skylight sizes for an office while providing enough daylight, avoiding glare and saving energy
… excessive daylight may cause glare issues and visual discomfort which need to be avoided in daylight design. Beyond all the qualitative aspects of daylight, daylight, as a free resource, is able to illuminate the space and replace electrical lighting and lower electricity utility bills. This …
