This study explored the relationship between surrounding avatars and time perception in a virtual reality (VR) gymnasium. Previous research has highlighted that motion speed and exercise intensity significantly influence time perception. In VR, time perception is shaped by various factors, such as an avatar's embodiment at different levels. However, the specific effects of the surrounding avatar on time perception in a VR gymnasium context remain unclear. Thus, this study focuses on two key attributes of the surrounding avatar: (1) motion speeds and (2) exercise intensity. Participants in a VR gymnasium either rode a stationary bike or sat on one while observing avatars performing exercises in the virtual environment(VE). They were then asked to estimate the duration judgment and the feeling of the passage of time for each task. The results revealed that when the surrounding avatars exercised at a faster motion speed, participants perceived the duration of time as longer and felt that time passed more quickly. Additionally, high-intensity exercise led participants to perceive the passage of time as faster.
本研究探讨了虚拟现实（VR）体育馆中周围虚拟形象与时间感知之间的关系。先前的研究强调，运动速度和运动强度会显著影响时间感知。在VR中，时间感知受多种因素影响，比如虚拟形象在不同层面的体现。然而，在VR体育馆环境中，周围虚拟形象对时间感知的具体影响仍不明确。因此，本研究聚焦于周围虚拟形象的两个关键属性：（1）运动速度和（2）运动强度。VR体育馆中的参与者要么骑固定自行车，要么坐在自行车上同时观察虚拟环境（VE）中正在锻炼的虚拟形象。然后要求他们估计每项任务的持续时间判断和时间流逝的感觉。结果显示，当周围的虚拟形象以更快的运动速度锻炼时，参与者会觉得时间持续更长，并且感觉时间过得更快。此外，高强度运动使参与者感觉时间流逝更快。
