Abstract

Reading on mobile phones can cause visual discomfort, negatively affecting visual health. Most studies have focused on neutral text-background combinations, with limited validation for coloured text-background combinations. This study investigates the impact of coloured text on neutral backgrounds and the colour difference between text and background on visual comfort during digital reading. A psychophysical experiment was conducted, where 230 images of coloured text on neutral backgrounds were evaluated by 20 participants using a 6-point scale for visual comfort. Results showed that reading coloured text on a black background generally provided higher comfort compared to a white background. Additionally, visual comfort decreased as the text colour approached that of the background. The effect of text hue on comfort was not significant. Furthermore, several visual comfort models for mobile displays were developed and compared. The VC_1-LAB model is based on Bern’s attributes, while the VC_2-LAB model focuses on the lightness of text and background. The VC_3-LAB model includes both lightness and chroma attributes. Comparisons revealed that VC_3-LAB outperformed the others in predicting visual comfort, highlighting the importance of lightness and chroma in improving predictive accuracy. Therefore, the VC_3-LAB model is useful for evaluating the visual comfort of coloured text on neutral backgrounds.

基于彩色文本和中性背景组合的视觉舒适模型

在手机上阅读会引起视觉不适，对视觉健康产生负面影响。大多数研究都集中在中性文本-背景组合上，对有色文本-背景组合的验证有限。本研究探讨了彩色文本在中性背景上的影响，以及文本和背景之间的颜色差异对数字阅读视觉舒适度的影响。研究人员进行了一项心理物理实验，其中20名参与者使用6分制的视觉舒适度来评估230张中性背景上的彩色文字图像。结果表明，在黑色背景上阅读彩色文本通常比在白色背景上阅读更舒适。此外，当文字颜色接近背景颜色时，视觉舒适度下降。文字色调对舒适度的影响不显著。此外，还开发了几种移动显示器的视觉舒适模型并进行了比较。VC1-LAB模型基于Bern的属性，而VC2-LAB模型侧重于文本和背景的亮度。VC3-LAB模型包括亮度和色度属性。比较显示，VC3-LAB在预测视觉舒适度方面优于其他方法，突出了亮度和色度在提高预测准确性方面的重要性。因此，VC3-LAB模型对于评估中性背景上彩色文本的视觉舒适度是有用的。

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.
