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.

使用触觉提示增强人体对移动威胁的规避

新的以人为本的安全方法可以将头顶摄像头视图与态势感知工具相结合，使人类能够避免快速演变的威胁，例如移动的机器或掉落的碎片。本文探讨了如何使用 360° 信息通知人类潜在的碰撞。具体来说，我们量化了不同的个体（触觉、听觉和视觉）和组合提示模式如何影响失败率和反应时间。人类-受试者实验是在自定义虚拟现实环境中进行的，该环境模拟快速向受试者移动的物体。为了成功执行他们的任务，人类主体必须在碰撞发生之前将他们的身体从移动威胁的路径上移开。这种对全身身体反应的探索使本文与之前的相关研究区分开来。18 名受试者研究的结果提供了一系列线索和线索组合的量化数据。该研究将故障率和反应时间量化为难度指数（菲特定律）和威胁方向的函数。结果证实了这样一个假设，即与非触觉提示相比，触觉提示的添加在统计上提高了失效率和反应时间方面的性能。这展示了感官线索如何改善人类对快速威胁的身体反应。结果证实了这样的假设，即与非触觉提示相比，触觉提示的添加在统计上提高了失效率和反应时间方面的性能。这展示了感官线索如何改善人类对快速威胁的身体反应。结果证实了这样的假设，即与非触觉提示相比，触觉提示的添加在统计上提高了失效率和反应时间方面的性能。这展示了感官线索如何改善人类对快速威胁的身体反应。
