We present exploratory research of virtual reality techniques and mnemonic devices to assist in retrieving knowledge from scholarly articles. We used abstracts of scientific publications to represent knowledge in scholarly articles; participants were asked to read, remember, and retrieve knowledge from a set of abstracts. We conducted an experiment to compare participants' recall and recognition performance in three different conditions: a control condition without a pre-specified strategy to test baseline individual memory ability, a condition using an image-based variant of a mnemonic called a "memory palace," and a condition using a virtual reality-based variant of a memory palace. Our analyses show that using a virtual reality-based memory palace variant greatly increased the amount of knowledge retrieved and retained over the baseline, and it shows a moderate improvement over the other image-based memory palace variant. Anecdotal feedback from participants suggested that personalizing a memory palace variant would be appreciated. Our results support the value of virtual reality for some high-level cognitive tasks and help improve future applications of virtual reality and visualization.

虚拟现实记忆宫殿变体有助于从学术文章中检索知识。

我们展示了虚拟现实技术和助记符设备的探索性研究，以帮助从学术文章中检索知识。我们使用科学出版物的摘要来表示学术文章中的知识；参与者被要求从一组摘要中阅读、记忆和检索知识。我们进行了一项实验来比较参与者在三种不同条件下的回忆和识别性能：没有预先指定策略的对照条件来测试基线个人记忆能力，使用基于图像的助记符变体的条件，称为“记忆宫殿”， “以及使用基于虚拟现实的记忆宫殿变体的条件。我们的分析表明，使用基于虚拟现实的记忆宫殿变体在基线上大大增加了检索和保留的知识量，并且与其他基于图像的记忆宫殿变体相比，它显示出适度的改进。参与者的轶事反馈表明，个性化记忆宫殿变体将受到赞赏。我们的结果支持虚拟现实对一些高级认知任务的价值，并有助于改进虚拟现实和可视化的未来应用。
