摘要
探究年龄对动态有效视野特征变化的影响。采用动态视觉搜索任务,共测试样本138人。研究结果表明,年龄对动态有效视野特性具有显著影响,随着年龄增加,有效视野面积、有效视野周长和形状因子随之下降;视野特性受凝视点移动速度影响,随着速度增加,视野范围有缩小且视野形状偏离圆形的趋势。本文的研究可为针对不同年龄段人群设计动态视觉搜索任务提供指导。
The influence of age on the changes of dynamic visual lobe characteristics is explored.Using dynamic visual search tasks,a total of 138 samples are tested.The results show that age significantly affects the visual lobe area,the dynamic visual lobe area,dynamic visual lobe perimeter and shape factor which all decrease with the increase of age.The dynamic visual lobe characteristics are affected by the moving speed of the gaze point.With the increase of speed,the visual field range decreases and the shape of the dynamic visual lobe deviates from the circle.The results of this study can provide guidance for designing dynamic visual search tasks for different age groups.
