| 摘 要： | 设计并开展了基于虚拟亲历行为的空间场所认知对比实验，探索基于头盔式虚拟现实地理信息系统(virtual reality geographic information system，VRGIS)与基于屏幕空间的地学虚拟环境中虚拟亲历行为的空间场所认知差异特征。实验收集到虚拟现实(virtual reality，VR)组与屏幕组两组参与者的数据，包括参与者手绘认知草图、虚拟场景中活动轨迹与视线轨迹数据，并从空间场所认知效果、遗忘分数、视线轨迹等3个方面进行了对比分析。结果表明，VR组的潜在优势体现在:①空间认知3个层次(空间特征感知、空间对象认知、空间格局认知)的认知效果比屏幕组均有了显著的提升；②在遗忘分数方面，与屏幕组并没有显著差别；③观察方向的水平变化量显著大于屏幕组。此外，实验还讨论了头盔式VRGIS影响空间场所认知效果的可能内在机制以及支撑虚拟地理实验平台的可能性。

| Abstract: | In this paper we present the design and implementation of a comparative experiment to study the differences in spatial cognition between head-mounted virtual reality geographic information systems (VRGIS) and desktop monitor-based virtual geographic environments, collect virtual travel behavior data from two groups of participants and explore the differences in spatial cognition. The collected virtual travel behavioral data include subjects' self-drawn cognitive maps, movement trajectories and viewing trajectories. Then the differences in spatial cognitive performance, forgetting scores and viewing trajectories are analyzed. The following conclusions are drawn:①The head-mounted VRGIS group scores significantly higher than desktop monitor-based group in three levels of spatial cognition including spatial feature perception, spatial object cognition and spatial pattern cognition. ②The two groups do not show a significant difference in forgetting scores. ③The average rate of change in horizontal viewing direction is significantly greater in the head-mounted VRGIS group than in desktop monitor-based group. Furthermore, we discuss the internal limiting factors of spatial cognition associated with head-mounted VRGIS and its potentials for supporting virtual geographic experiment development. |
