摘　　要：利用Unity 3D构建虚拟三维环境平台,设计了空间维度和长度距离两个因素的实验,目的是探索虚拟环境是否对空间距离的判断产生影响。实验结果表明:(1)在虚拟环境中,人们对距离的判断与真实值之间存在显著性差异;(2)在虚拟环境中,人们在不同维度下对短距离的判断之间存在显著性差异;其中,人们在垂直场景下对短距离的判断最为准确,人们在纵向场景下对短距离的判断比在横向场景下对短距离的判断更加准确。Using Unity 3D to construct the virtual 3D environment platform, the experiment described here consisted of two factors of spatial dimension and length distance, in order to explore whether the virtual environment has an influence on the judgment of spatial distance.The experimental results show that： ① in the virtual environment, there was a significant difference between the judgments of distance and the values of true distance, namely that it was different between the distance construction method in the virtual environment and the real distance;② in the virtual environment, there was a significant differences of short distance which was judged in different special dimensions, the judgment of short distance in vertical scene was most accurate in the three virtual scenes, while the judgment of short distance in longitudinal scene was more accurate than the transverse scene.
