The purpose of this study was to evaluate the effect the visual fidelity of a virtual environment (VE) (undetailed vs. detailed) has on the transfer of spatial knowledge based on the navigation mode (passive vs. active) for three different spatial recall tasks (wayfinding, sketch mapping, and picture sorting). Sixty-four subjects (32 men and 32 women) participated in the experiment. Spatial learning was evaluated by these three tasks in the context of the Bordeaux district. In the wayfinding task, the results indicated that the detailed VE helped subjects to transfer their spatial knowledge from the VE to the real world, irrespective of the navigation mode. In the sketch-mapping task, the detailed VE increased performances compared to the undetailed VE condition, and allowed subjects to benefit from the active navigation. In the sorting task, performances were better in the detailed VE; however, in the undetailed version of the VE, active learning either did not help the subjects or it even deteriorated their performances. These results are discussed in terms of appropriate perceptive-motor and/or spatial representations for each spatial recall task.
本研究旨在评估虚拟环境（VE）的视觉逼真度（不详细与详细）对三种不同空间回忆任务（寻路、草图绘制和图片分类）的基于导航模式（被动与主动）的空间知识迁移的影响。64 名受试者（32 名男性和 32 名女性）参与了实验。通过在波尔多地区的三个任务评估空间学习。在寻路任务中，结果表明，详细的 VE 有助于受试者将他们的空间知识从 VE 转移到现实世界，而与导航模式无关。在草图绘制任务中，与不详细的 VE 条件相比，详细的 VE 提高了表现，并且允许受试者受益于主动导航。在排序任务中，在详细的 VE 中表现更好；然而，在 VE 的不详细版本中，主动学习要么对受试者没有帮助，要么甚至降低了他们的表现。这些结果根据每个空间回忆任务的适当感知运动和/或空间表示进行了讨论。
