论文摘要
但是，通过VR场景引起的用户对用户的情感反应已成为一个有趣的话题，但是，在VR场景中改变对象的大小是否会引起不同级别的焦虑级别仍然是一个需要研究的问题。在这项研究中，我们进行了一项实验，最初揭示了VR环境中大物体的大小如何影响参与者的变化（n = 38）焦虑水平和心率。为了整体量化VR视野中的大对象的大小，我们首次使用了视图占用（OFVO）标准的全向视野，以表示参与者整个视野的对象的维度。结果表明，参与者在观察大物体时的心跳和焦虑与OFVO呈正相关。这些研究表明，VR环境中对象大小的增加伴随着更高程度的用户焦虑。
The emotional response of users induced by VR scenarios has become a topic of interest, however, whether changing the size of objects in VR scenes induces different levels of anxiety remains a question to be studied. In this study, we conducted an experiment to initially reveal how the size of a large object in a VR environment affects changes in participants' (N = 38) anxiety level and heart rate. To holistically quantify the size of large objects in the VR visual field, we used the omnidirectional field of view occupancy (OFVO) criterion for the first time to represent the dimension of the object in the participant's entire field of view. The results showed that the participants' heartbeat and anxiety while viewing the large objects were positively and significantly correlated to OFVO. These study reveals that the increase of object size in VR environments is accompanied by a higher degree of user's anxiety.
