Head-mounted displays (HMDs) are head-worn display devices that project an information display over the wearer's field of view. This article reviews a recent program of research that investigates the advantages and disadvantages of monitoring with HMDs, and discusses the design considerations and implementation issues that must be addressed before HMDs can be clinically adopted.
HMDs let anesthesiologists spend a larger proportion of their time in the operating room looking towards the patient and surgical field, and a correspondingly smaller proportion of time looking at the standard monitors. Anesthesiologists can detect patient events faster with an HMD when they are busy performing procedures, but not during normal monitoring. There was no evidence of anesthesiologists' performance or monitoring behavior being affected by perceptual issues with the HMD, and no evidence that more events were missed with the HMD due to inattentional blindness.
Anesthesiologists may be able to monitor their patients more effectively when an HMD is used in conjunction with existing monitors, but several engineering and implementation issues need to be resolved before HMDs can be adopted in practice. Further research is needed on the design of information displays for HMDs.
目的综述：头戴式显示器（HMD）是一种头戴式显示设备，可将信息显示投射到佩戴者的视野上方。本文综述了最近的一项研究计划，该计划调查了使用 HMD 进行监测的优缺点，并讨论了在 HMD 能够临床应用之前必须解决的设计考虑因素和实施问题。
最新发现：HMD 可让麻醉师在手术室中更多地将时间用于观察患者和手术区域，相应地减少了查看标准监视器的时间。当麻醉师在忙于手术时，使用 HMD 可以更快地检测到患者事件，但在正常监测期间则不行。没有证据表明麻醉师的表现或监测行为受到 HMD 的感知问题的影响，也没有证据表明由于疏忽性失明，使用 HMD 会错过更多事件。
总结：当 HMD 与现有的监视器一起使用时，麻醉师可能能够更有效地监测他们的患者，但在 HMD 实际应用之前，需要解决几个工程和实施问题。需要进一步研究 HMD 的信息显示设计。
