Immersive environments have been successfully applied to a broad range of safety training in high-risk domains. However, very little research has used these systems to evaluate the risk-taking behavior of construction workers. In this study, we investigated the feasibility and usefulness of providing passive haptics in a mixed-reality environment to capture the risk-taking behavior of workers, identify at-risk workers, and propose injury-prevention interventions to counteract excessive risk-taking and risk-compensatory behavior. Within a mixed-reality environment in a CAVE-like display system, our subjects installed shingles on a (physical) sloped roof of a (virtual) two-story residential building on a morning in a suburban area. Through this controlled, withinsubject experimental design, we exposed each subject to three experimental conditions by manipulating the level of safety intervention. Workers' subjective reports, physiological signals, psychophysical responses, and reactionary behaviors were then considered as promising measures of Presence. The results showed that our mixed-reality environment was a suitable platform for triggering behavioral changes under different experimental conditions and for evaluating the risk perception and risk-taking behavior of workers in a risk-free setting. These results demonstrated the value of immersive technology to investigate natural human factors.

存在，混合现实和冒险行为：安全干预研究。

沉浸式环境已成功应用于高风险领域的广泛安全培训。但是，很少有研究使用这些系统来评估建筑工人的冒险行为。在这项研究中，我们调查了在混合现实环境中提供被动触觉以捕获工人的冒险行为，识别高风险工人并提出预防伤害的干预措施以抵消过度冒险和风险的可行性和实用性。补偿行为。在一个类似CAVE的显示系统中的混合现实环境中，我们的受检者早上在郊区的一栋（虚拟）两层住宅楼的（物理）倾斜屋顶上安装了带状疱疹。通过这种受控的，主题内的实验设计，我们通过控制安全干预的水平，使每个受试者都处于三种实验条件下。然后，将工人的主观报告，生理信号，心理生理反应和反应行为视为有前途的衡量标准。结果表明，我们的混合现实环境是触发不同实验条件下的行为变化以及评估无风险环境中工人的风险感知和冒险行为的合适平台。这些结果证明了沉浸式技术对研究自然人为因素的价值。结果表明，我们的混合现实环境是触发不同实验条件下的行为变化以及评估无风险环境中工人的风险感知和冒险行为的合适平台。这些结果证明了沉浸式技术对研究自然人为因素的价值。结果表明，我们的混合现实环境是触发不同实验条件下的行为变化以及评估无风险环境中工人的风险感知和冒险行为的合适平台。这些结果证明了沉浸式技术对研究自然人为因素的价值。
