目的 探讨在使用3D显示器时,瞳孔直径变化与视疲劳的关系.方法 通过瞳孔直径的测量装置,记录10名受试者在使用3D显示器观看5段立体视频时瞳孔的变化,并与观看者的主观评价相结合.结果 受试者在使用3D显示器观看立体视频时,视疲劳程度随着观看时间的增加而加剧,同时受试者的瞳孔直径也随着观看时间的增加而变大,视疲劳程度与瞳孔直径的变化呈正相关关系.结论 瞳孔直径可作为一种新的视疲劳度量的简单指标.%Objective The purpose of this study was to analyze the degree of visual fatigue that increases with the pupil diameter when viewing stereoscopic videos. Method Ten subjects, aging between 20 and 23 years old, were asked to view 5 clips of stereoscopic videos for 10 minutes. Pupil diameter was measured during the viewing process by a pupil-ometer. A questionnaire on perceived visual fatigue was completed at the end of the process. Results The results showed that the perceived visual fatigue increases with the pupil diameter. Conclusion Pupil diameter during viewing activity can be used to predict perceived visual fatigue.
