如今，mooc等在线学习平台已经成为人们自主学习的普遍来源。然而，缺乏同伴陪伴和社会互动可能会增加学习者的孤立感。先前的研究表明，在虚拟现实学习环境中，视觉化同伴学生的外表具有积极作用。在这项工作中，我们建议通过综合以前学习者的时间锚定信息来构建虚拟同学。虚拟同学的配置和行为特征是可以调整的。为了构建虚拟同学的特征，我们开发了一种称为评论映射的技术，以聚合先前在线学习者的评论来塑造虚拟同学的行为。我们评估了使用和不使用评论映射构建的虚拟同学的效果，以及在VR中呈现的虚拟同学的数量。
Online learning platforms such as MOOCs have been prevalent sources of self-paced learning to people nowadays. However, the lack of peer accompaniment and social interaction may increase learners' sense of isolation. Prior studies have shown the positive effects on visualizing peer students' appearances in VR learning environments. In this work, we propose to build virtual classmates, which were constructed by synthesizing previous learners' time-anchored messages. Configurations of virtual classmates and their behavioral features can be adjusted. To build the characteristics of virtual classmates, we developed a technique called comment mapping to aggregate prior online learners' comments to shape virtual classmates' behaviors. We evaluated the effects of the virtual classmates built with and without the comment mapping and the amount of virtual classmates rendered in VR.
