不幸的是，活跃的枪手事件在美国呈上升趋势。随着最近的技术进步，虚拟现实(VR)实验可以作为一种有效的方法，让平民和执法人员为此类场景做好准备。然而，要想让VR实验有效地进行主动射击训练和研究，此类实验必须能够像现场主动射击训练和活动那样唤起情感和生理反应。因此，本研究的目的是测试主动射击VR实验对情绪和生理反应的有效性。此外，我们考虑了不同的移动技术(即原地漫步和控制器)，并探讨了它们对用户临场感的影响。结果表明，本研究中的VR主动射击实验可以诱导沉浸在虚拟环境中的参与者的情绪唤醒和心率增加。此外，与控制者相比，就地行走技术导致了更高的负面情绪唤醒和更强的现场感。这项研究为未来的主动射击实验奠定了基础，因为它支持将VR用于主动射击事件相关工作的生态有效性，以达到训练或研究的目的。
Unfortunately, active shooter incidents are on the rise in the United States. With the recent technological advancements, virtual reality (VR) experiments could serve as an effective method to prepare civilians and law enforcement personnel for such scenarios. However, for VR experiments to be effective for active shooter training and research, such experiments must be able to evoke emotional and physiological responses as live active shooter drills and events do. The objective of this study is thus to test the effectiveness of an active shooter VR experiment on emotional and physiological responses. Additionally, we consider different locomotion techniques (i.e., walk-in-place and controller) and explore their impact on users' sense of presence. The results suggest that the VR active shooter experiment in this study can induce emotional arousal and increase heart rate of the participants immersed in the virtual environment. Furthermore, compared to the controller, the walk-in-place technique resulted in a higher emotional arousal in terms of negative emotions and a stronger sense of presence. The study presents a foundation for future active shooter experiments as it supports the ecological validity using VR for active shooter incident related work for the purposes of training or research.
