摘要: 本文探究动态视觉搜索任务中显示移动速度对视觉疲劳的影响。研究采用动态视觉搜索任务,移动速度设置为0°/s,2°/s,4°/s,6°/s,8°/s。视觉疲劳程度由临界闪烁频率衡量。结果表明搜索时间在40 min以内,视觉疲劳程度随搜索时间增加而增加。移动速度为2°/s时的视觉疲劳度与移动速度为0°/s时的视觉疲劳度没有显著差异。当移动速度在2°/s~6°/s时,视觉疲劳度随移动速度的增加而增加。移动速度为6°/s时的视觉疲劳度与移动速度为8°/s时的视觉疲劳度没有显著差异。

关键词: 视觉疲劳, 动态视觉搜索, 移动速度, 临界闪烁频率

Abstract: The study aimed to investigate the effect of display movement speed on visual fatigue in dynamic visual search tasks. The movement speed had five levels: 0°/s, 2°/s, 4°/s, 6°/s, and 8°/s. The visual fatigue was measured by critical flicker frequency (CFF). The analysis of variance (ANOVA) results indicated that for dynamic visual search tasks, the main effects of movement speed and search time point on visual fatigue were significant and their interaction effect was also significant. Within 40min search time, visual fatigue increased as search time increased. When performing search tasks after 40 minutes, the visual fatigue became steady. The visual fatigue at 0°/s showed no significant difference with that at 2°/s. When the movement speed was in the range of 2°/s to 6°/s, the visual fatigue increased as movement speed increased. The visual fatigue at 6°/s showed no significant difference with the visual fatigue at 8°/s.

Key words: visual fatigue, dynamic visual search, movement speed, critical flicker frequency
