Abstract Falling from elevated surfaces is the leading cause of death and injury at construction sites. Dynamic instability is mostly the reason for these falls. By using virtual reality (VR) simulations, previous studies have shown that biomechanical measurements of gait are reliable indicators of fall risk. Despite success in understanding critical factors of falling, these studies mostly overlooked simulations of visual biofeedback in their fall-risk assessments or employed limited-range, orientation-sensitive systems to generate such simulations. To facilitate these endeavors and better understand gait performance at height, this paper proposes and examines a reliable and responsive VR simulator (VS) as a testbed for assessing ironworkers' fall risk. The experimental results on 12 healthy adults show VS surpasses traditional virtual reality systems in evaluating upper-limb stability during gait at height. Such improvement can lead to more effective fall-related safety training. The findings can open doors to enhancements of VR simulation for hazard-prevention techniques.

使用沉浸式生物反馈模拟器比较钢铁工人跌倒风险评估系统

摘要 从高处坠落是建筑工地死亡和受伤的主要原因。动态不稳定性主要是这些下降的原因。通过使用虚拟现实 (VR) 模拟，先前的研究表明，步态的生物力学测量是跌倒风险的可靠指标。尽管在理解跌倒的关键因素方面取得了成功，但这些研究在跌倒风险评估中大多忽略了视觉生物反馈的模拟，或者使用有限范围、方向敏感的系统来生成此类模拟。为了促进这些努力并更好地了解高处步态表现，本文提出并检验了一种可靠且响应迅速的 VR 模拟器 (VS)，作为评估铁工跌倒风险的测试平台。对 12 名健康成年人的实验结果表明，VS 在评估高处步态时的上肢稳定性方面优于传统的虚拟现实系统。这种改进可以导致更有效的与跌倒相关的安全培训。这些发现可以为增强 VR 模拟的危害预防技术打开大门。
