新的以人为中心的安全方法可以将头顶摄像头的视角与态势感知工具相结合，使人类能够避免快速演变的威胁，如移动的机器或坠落的碎片。这篇文章探讨了如何使用360度信息来通知人类潜在的碰撞。具体地说，我们量化了不同的个体(触觉、听觉和视觉)和组合线索形态如何影响失败率和反应时间。人体受试者实验是在一个定制的虚拟现实环境中进行的，该环境模拟物体快速向受试者移动。为了成功地完成任务，人类受试者必须在碰撞发生之前将身体从移动的威胁的路径中移出。这种对全身生理反应的探索使本文有别于以前的相关研究。这项由18名受试者参与的研究结果提供了一系列线索和线索组合的量化数据。这项研究量化了失败率和反应时间，作为难度指数(菲特定律)和威胁方向性的函数。结果证实了这样一种假设，即与非触觉线索相比，加入触觉线索在失败率和反应时间方面具有统计学意义上的改善。这展示了感官提示如何改善人类对快速威胁的身体反应。
New human-centric approaches to safety can combine over-head camera views with situational awareness tools to enable humans to avoid rapidly evolving threats such as moving machines or falling debris. This article explores how 360° information can be used to inform humans of potential collisions. Specifically, we quantify how different individual (tactile, audio, and visual) and combined cue modalities affect failure rates and reaction times. Human-subject experiments were conducted in a custom virtual reality environment that simulates objects rapidly moving toward the subject. In order to successfully perform their task, the human subject must physically move their body out of the path of the moving threat before a collision occurs. This exploration of full body physical response differentiates this article from previous related studies. The results of the 18-subject study provide quantified data on a range of cues and cue combinations. The study quantified failure rates and reaction times as a function of index of difficulty (Fitt's Law) and threat directionality. The results confirm the hypothesis that the addition of tactile cues statistically improve performance compared to non-tactile cues with regards to failure rate and reaction time. This demonstrates how sensory cues can improve human physical response to rapid threats.
