In hospitals, clinicians often need to monitor several patients while performing other tasks. However, visual displays that show patients' vital signs are in fixed locations and auditory alarms intended to alert clinicians may be missed. Information such as spearcons (time-compressed speech earcons) that 'travels' with the clinician and is delivered by earpiece and/or head-worn displays (HWDs), might overcome these problems. In this study, non-clinicians monitored five simulated patients in three 10-min scenarios while performing a demanding tracking task. Monitoring accuracy was better for participants using spearcons and a HWD (88.7%) or a HWD alone (86.2%) than for participants using spearcons alone (74.1%). Participants using the spearcons and HWD (37.7%) performed the tracking task no differently from participants using spearcons alone (37.1%) but participants using the HWD alone performed worse overall (33.1%). The combination of both displays may be a suitable solution for monitoring multiple patients.
在医院中，临床医生在执行其他任务时经常需要同时监测多个患者。然而，显示患者生命体征的视觉显示器通常位于固定位置，而旨在提醒临床医生的听觉警报可能会被忽略。例如，与临床医生“同行”并通过耳机和/或头戴式显示器（HWD）传递的 spearcone（时间压缩语音耳标）等信息可能会克服这些问题。在这项研究中，非临床医生在三个 10 分钟的场景中监测了五个模拟患者，同时执行了一项要求很高的跟踪任务。使用 spearcone 和 HWD（88.7%）或仅使用 HWD（86.2%）的参与者的监测准确性优于仅使用 spearcone 的参与者（74.1%）。使用 spearcone 和 HWD 的参与者（37.7%）执行跟踪任务的表现与仅使用 spearcone 的参与者（37.1%）相同，但仅使用 HWD 的参与者总体表现更差（33.1%）。这两种显示器的组合可能是监测多个患者的合适解决方案。
