Wearable Augmented Reality Displays (WARDs) present situated, real-time information visually, providing immediate access to information to support decision making. The impacts of WARD use on operator performance, Situation Awareness (SA), and communication in one safety-critical system, marine transportation, were examined in a real-time physical simulator. WARD use improved operator trackkeeping performance, the practice of good seamanship, and SA, although operator responsiveness decreased. WARD users who used more closed-loop communication and information sharing showed improved threat avoidance, suggesting that operators can avoid accidents and failure through WARD use that promotes sharing and confirming information. WARD use also promoted information source diversity, a means of developing requisite variety. These operational impacts are important in safety-critical settings where failures can be catastrophic.
可穿戴式增强现实显示器 (WARD) 以视觉方式呈现即时的情境信息，为支持决策提供了即时访问信息的途径。在一个实时物理模拟器中，研究了 WARD 在一个安全关键系统——海洋运输中的操作人员绩效、态势感知 (SA) 和通信方面的影响。WARD 的使用提高了操作人员的跟踪性能、良好航海技术的实践和 SA，尽管操作人员的响应能力下降了。使用更多闭环通信和信息共享的 WARD 用户表现出更好的威胁回避能力，这表明操作人员可以通过促进信息共享和确认的 WARD 使用来避免事故和故障。WARD 的使用还促进了信息源的多样性，这是发展必要多样性的一种手段。这些操作方面的影响在可能造成灾难性后果的安全关键环境中非常重要。
