目的评估基于凝视的指标在检测外科手术所施加的认知需求方面的敏感性。我们分析了泌尿科医生的凝视熵和速度，同时执行2个标准化的高保真模拟结石手术，具有不同的复杂程度。（安装在一个可移动的框架上），我们测量了15名安达卢西亚医疗保健系统的泌尿科医生的凝视熵和速度，同时他们进行了膀胱结石的取出（低复杂性）和腰椎输尿管结石的取出（高复杂性）。我们还收集了性能和主观data.RESULTS凝视熵和速度显着较高时，外科医生进行最复杂的手术程序：视觉探索模式变得不那么刻板（即，更随机）和更快。外科医生的性能和感知任务的复杂性相应地不同，确认凝视为基础的results.CONCLUSION基于凝视的指标可能有很大的潜力，客观和非侵入性的指标，以评估外科医生的认知（过）负荷，潜在的是一个补充的评估工具，以量化的学习曲线的外科手术。(C)2017爱思唯尔公司
OBJECTIVE To assess the sensitivity of gaze-based metrics in detecting cognitive demands imposed by surgical procedures. We analyzed urologists' gaze entropy and velocity while performing 2 standardized high-fidelity simulated stone procedures with different levels of complexity.METHODS Using a wearable eye tracker device (mounted onto an eyeglass frame), we measured gaze entropy and velocity in 15 urologists, members of the Andalusian health-care system, while they performed an extraction of a stone in the bladder (low complexity) and an extraction of a stone in the lumbar ureter (high complexity). We also collected performance and subjective data.RESULTS Gaze entropy and velocity were significantly higher when surgeons performed the most complex surgical procedure: the visual exploration pattern became less stereotyped (ie, more random) and faster. Surgeons' performance and perceived task complexity differed accordingly, confirming the gaze-based results.CONCLUSION Gaze-based metrics might have great potential as objective and nonintrusive indices to assess surgeons' cognitive (over) load, potentially being a complementary assessment tool to quantify the learning curve for surgical procedures.
