Nurses are responsible for comprehensively identifying patient conditions and associated environments. We hypothesize that gaze trajectories of nurses differ based on their experiences, even under the same situation.
An eye-tracking device monitored the gaze trajectories of nurses with various levels of experience, and nursing students during the intravenous injection task on a human patient simulator.
The areas of interest (AOIs) were identified in the recorded movies, and the gaze durations of AOIs showed different patterns between experienced nurses and nursing students. A state transition diagram visualized the recognition errors of the students and the repeated confirmation of the vital signs of the patient simulator. Clustering analysis of gaze durations also indicated similarity among the participants with similar experiences.
As expected, gaze trajectories differed among the participants. The developed gaze transition diagram visualized their differences and helped in interpreting their situational awareness based on visual perception. The demonstrated method can help in establishing an effective nursing education, particularly for learning the skills that are difficult to be verbalized.
护士负责全面识别患者病情及相关环境。我们推测，即使在相同情况下，护士的注视轨迹也会因其经验不同而有所差异。
使用眼动追踪设备监测不同经验水平的护士以及护理专业学生在人体患者模拟器上进行静脉注射任务时的注视轨迹。
在录制的影片中确定了感兴趣区域（AOI），经验丰富的护士和护理专业学生在AOI的注视时长呈现出不同模式。状态转换图直观展示了学生的识别错误以及对患者模拟器生命体征的反复确认。注视时长的聚类分析也表明，具有相似经验的参与者之间存在相似性。
正如预期的那样，参与者之间的注视轨迹存在差异。所开发的注视转换图直观呈现了这些差异，并有助于基于视觉感知来解读他们的情境意识。所展示的方法有助于建立有效的护理教育，特别是对于学习难以言传的技能。
