| 摘要: |
| 视觉显示终端（visual display terminal,VDT）和纸质文稿共同成为人们生活和学习中不可或缺的阅读媒介,提供适宜的VDT与纸质交互阅读照明环境是提升室内照明环境质量、满足人民健康需求的重要发展方向。为探讨照明环境对交互阅读的视觉和认知的影响,采用主观评价、视觉任务绩效和生理指标测量相结合的方法,开展照明环境主客观评价实验。搭建了交互阅读照明环境实验平台,研究了水平照度、照度配比、色温、屏幕亮度4项照明参数对交互阅读视觉舒适、视觉功效、视觉疲劳3种视觉感知,认知效率和情绪唤醒2种认知表现的影响。实验结果显示,水平照度对视觉疲劳影响最大；照度配比主效应对交互阅读的视觉感知和认知表现均有显著影响；光源色温对交互阅读视觉舒适和视觉功效影响最大；VDT屏幕亮度对交互阅读视觉疲劳、认知效率和情绪唤醒影响最大。根据各相关要素对评价指标的影响分析,得出高视觉舒适且高情绪唤醒的交互阅读最佳照明环境参数为水平照度750 lx、垂直照度300 lx（照度配比2.5）、色温4 000 K,最佳屏幕亮度为100 cd/m2；高视觉功效以及高认知效率、低视觉疲劳的交互阅读最佳照明环境参数为:水平照度300 lx、垂直照度200 lx（照度配比1.5）、色温5 000 K,且屏幕亮度建议为100 cd/m2。研究结果为交互阅读的照明设计和优化提供依据。 |

| Abstract: |
| Visual display terminal (VDT) and paper are indispensable reading mediums in peoples life. Providing suitable lighting environment for VDT and paper interactive reading is an important development direction to improve the quality of indoor lighting environment and meet public health needs. In order to explore the impact of lighting environment on the vision and cognition of interactive reading, we conducted subjective and objective evaluation experiments by using a combination method of subjective evaluation, visual task performance, and physiological index measurement. An experimental platform was established to study the effects of four lighting parameters (horizontal illuminance, illuminance ratio, color temperature, and screen brightness) on the visual perception (visual comfort, visual efficacy, and visual fatigue) and cognitive performance (cognitive efficiency and emotional arousal) of interactive reading. Experimental results show that for interactive reading, horizontal illuminance had the greatest impact on visual fatigue. Illuminance ratio had a significant impact on visual perception and cognitive performance. The color temperature of the light source had the greatest impact on visual comfort and visual efficacy. The brightness of the VDT screen had the greatest impact on visual fatigue, cognitive efficiency, and emotional arousal. According to parameter analysis, the optimal lighting environment parameters for interactive reading with high visual comfort and high emotional arousal are horizontal illuminance 750 lx, vertical illuminance 300 lx (illuminance ratio 2.5), and color temperature 4 000 K, and the best screen brightness is 100 cd/m2. The optimal lighting environment parameters for interactive reading with high visual efficiency, high cognitive efficiency, and low visual fatigue are horizontal illuminance 300 lx, vertical illuminance 200 lx (illuminance ratio 1.5), and color temperature 5 000 K, and the recommended screen brightness is 100 cd/m2. The results can provide basis for the lighting design and optimization of interactive reading. |
