Abstract Light reaching the retina elicits ocular symptoms that lead to some changes of human physiology and performance. However, its influence on ocular system is still unclear due to the lack of comprehensive analysis of ocular parameters. This study investigated the effects of corneal illuminance and display area on the oculomotor system based on eye-tracking technology, and a visual display unit was used as the illumination source. Results showed that oculomotor symptoms were sensitive to not only corneal illuminance but also display area. Fewer microsaccades, longer microsaccade duration and slower microsaccade peak velocity were found under high corneal illuminance, as well as longer fixation duration and faster saccade velocity. More microsaccades, shorter microsaccade duration and slower saccade velocity were observed under large display area. Pupil dilated with decreased corneal illuminance and increased display area. We conclude that oculomotor symptoms can be triggered by corneal illuminance and display area, which regulates human physiology and performance.

基于眼动追踪数据的显示区域和角膜照度对动眼系统的影响

摘要 光线到达视网膜会引起眼部症状,从而导致人体生理和机能的一些变化。然而,由于缺乏对眼部参数的综合分析,其对眼部系统的影响尚不清楚。本研究基于眼动追踪技术研究角膜照度和显示区域对动眼神经系统的影响,并以视觉显示单元作为照明源。结果表明,动眼神经症状不仅对角膜照度敏感,而且对显示区域敏感。在高角膜照度下发现较少的微跳跳、较长的微跳跳持续时间和较慢的微跳跳峰值速度,以及较长的注视持续时间和较快的跳跳速度。更多的微跳,在大显示区域下观察到较短的微跳视持续时间和较慢的跳视速度。瞳孔扩大,角膜照度降低,显示面积增加。我们得出结论,眼球运动症状可由角膜照度和显示区域触发,其调节人体生理机能和表现。
