Mobile displays provide operators in safety-critical systems with real-time information access when tasks require mobility in the working environment. Little empirical work has explored the impact of mobile displays on operator mobility or the impacts of operator mobility on operator performance and situation awareness (SA) in safety-critical settings. This work explores the impacts of head-mounted displays (HMDs) on operators in a real-time physical simulation of maritime navigation. HMD use significantly improved operator performance, SA, and mobility. These results suggest that the contextual information provided to mobile operators by HMDs may reduce information retrieval effort and allow operators to maintain SA without returning to fixed displays. This underscores longstanding training and domain requirements encouraging operator mobility throughout safety-critical systems, indicating a link between increased mobility and improved performance and SA that has not been empirically tested before.

当任务需要在工作环境中移动时，移动显示器为安全关键系统中的操作员提供实时信息访问。很少的经验工作探索了移动显示器对操作员移动性的影响，或在安全关键的环境中操作员移动性对操作员绩效和态势感知（SA）的影响。这项工作探索了海上实时实时物理仿真中的头戴式显示器（HMD）对操作员的影响。使用HMD可显着改善操作员的性能，SA和移动性。这些结果表明，HMD向移动运营商提供的上下文信息可以减少信息检索工作，并允许运营商维护SA而无需返回固定显示。
