摘要

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 realtime 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 safetycritical systems, indicating a link between increased mobility and improved performance and SA that has not been empirically tested before.
