Abstract

Flickering 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 chromatic contrast between two flickering colors in a uniform field influences discomfort. Participants rated their subjective discomfort for various flickering color combinations defined by the CIE L*a*b* uniform color space. Overall, discomfort increased with both chromatic and brightness contrasts. Additionally, flickers containing highly saturated red generally caused greater discomfort compared to those without red, an effect not observed with low saturation. Our findings suggest that visual discomfort induced by time-varying chromatic patterns is partly influenced by chromatic contrast over time. Furthermore, unlike the spatial domain, discomfort in the temporal domain may be specifically associated with the hue of red.

视觉不适和色频闪烁

色度变化的闪烁图案会让人感到不适，并可能诱发癫痫发作，但其根本原因尚不完全清楚。在空间领域，图像中的色度对比是视觉不适的潜在预测因素，对比度越高，不适感通常越强。本研究调查了均匀视野中两种闪烁颜色之间的色度对比是否会影响不适感。受试者对 CIE L*a*b* 统一色彩空间定义的各种闪烁色彩组合进行了主观不适感评分。总体而言，不适感会随着色度和亮度对比的增加而增加。此外，与不含红色的闪烁相比，含有高饱和度红色的闪烁通常会引起更大的不适感，而低饱和度的闪烁则不会产生这种效果。我们的研究结果表明，随时间变化的色度模式所引起的视觉不适在一定程度上受到随时间变化的色度对比的影响。此外，与空间域不同，时间域的不适感可能与红色的色调有特殊关联。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
