我们的目标是进一步探索空间知识从虚拟到真实的空间的转移。基于先前对沉浸式虚拟现实（VR）中空间记忆的研究，我们进行了一项研究，研究了三种运动技术（操纵杆，指向和心灵传送和原地行走）对物体位置学习和回忆的影响。参与者被要求学习虚拟环境（VE）中虚拟对象的位置。一段时间后，他们被要求通过将该物体的真实的版本放在现实世界的等效环境中来回忆该位置。结果表明，平均放置误差，或原始和召回的对象位置之间的距离，是约20厘米的所有运动技术条件。这一结果类似于以前的一项研究的结果空间记忆的虚拟环境，使用真实的步行。我们报告了这一意外的发现，并建议在VR中进一步研究空间记忆，建议在不同的环境中复制这项研究，并使用具有更广泛特性的物体，包括不同的大小和形状。
We aim to further explore the transfer of spatial knowledge from virtual to real spaces. Based on previous research on spatial memory in immersive virtual reality (VR) we ran a study that looked at the effect of three locomotion techniques (joystick, pointing-and-teleporting and walking-in-place) on object location learning and recall. Participants were asked to learn the location of a virtual object in a virtual environment (VE). After a short period of time they were asked to recall the location by placing a real version of the object in the real-world equivalent environment. Results indicate that the average placement error, or distance between original and recalled object location, is approximately 20cm for all locomotion technique conditions. This result is similar to the outcome of a previous study on spatial memory in VEs that used real walking. We report this unexpected finding and suggest further work on spatial memory in VR by recommending the replication of this study in different environments and using objects with a wider diversity of properties, including varying sizes and shapes.
