PURPOSE
The purpose of this study was to explore the effects of factors affecting depth perception of moving objects using a modified three-rods test, which can be used at longer distances than the conventional one, and to compare differences in the results between binocular and monocular vision.
METHODS
This study included 24 volunteers (10 women, 14 men; mean age, 35.2 years; standard deviation, 6.8 years; range, 22-56 years). We measured depth perception using a modified three-rods test under eight different conditions and investigated the factors affecting depth perception using a linear-effect model.
RESULTS
The results identified test distance, binocularity, masking, and direction of movement as significant factors affecting depth perception of a moving object.
CONCLUSIONS
The current study successfully determined factors affecting depth perception using the three-rods test with a moving object and the results should contribute to further clinical and social applications of the three-rods test.
目的
本研究旨在利用改良三杆试验探讨影响移动物体深度知觉的因素，该试验比传统试验可用于更远的距离，并比较双眼视觉和单眼视觉结果的差异。
方法
本研究纳入24名志愿者（10名女性，14名男性；平均年龄35.2岁；标准差6.8岁；范围22 - 56岁）。我们在八种不同条件下使用改良三杆试验测量深度知觉，并使用线性效应模型研究影响深度知觉的因素。
结果
结果确定测试距离、双眼视、遮挡和运动方向是影响移动物体深度知觉的重要因素。
结论
本研究成功地利用移动物体的三杆试验确定了影响深度知觉的因素，结果应有助于三杆试验在临床和社会方面的进一步应用。
