These days, eye-tracking is one of the promising technologies used in different fields such as aviation, arts, sports, psychology and driving for several purposes. Even though it is being used for health purposes, studies involving eye-tracking are rare in the field of endo-neurosurgery. This study aims to use this technology to promote our understanding of the effect related to computer-based instructional materials on mental workload of endo-neurosurgery residents. Four computer-based simulation scenarios are developed based on skill development requirements of endo-neurosurgery residents. Two of them were designed as general models and the other two as simulated surgical models. During these surgery procedures, in real settings, surgical residents need to use their both hands simultaneously to control the endoscope and the operational tool in a coordinated fashion. Therefore, to shed light on the participants' behaviors, these scenarios are performed with dominant-hand, non-dominant hand and, finally with both-hands using haptic interfaces. Twenty-three residents volunteered in this study. Their eye-movements were recorded while performing the scenarios. According to the results of this study, when performing the simulated surgical models, an increase in the participants' mental workload was recorded when compared to the other scenarios. Accordingly, it can be concluded that the eye-movements of surgical residents can provide insights about the anticipated level of difficulty about the skill-based tasks. This information might be very critical to properly design and organize instructional materials for endo-neurosurgery, and also to better guide and evaluate the progress of trainees in computer simulation-based skill training environments.
如今，眼动追踪是一项很有前景的技术，被用于航空、艺术、体育、心理学和驾驶等不同领域，有多种用途。尽管它被用于健康目的，但在神经内镜手术领域，涉及眼动追踪的研究却很少。本研究旨在利用这项技术增进我们对基于计算机的教学材料对神经内镜手术住院医师心理负荷影响的理解。根据神经内镜手术住院医师的技能发展要求，开发了四个基于计算机的模拟场景。其中两个被设计为通用模型，另外两个为模拟手术模型。在这些手术过程中，在实际操作中，外科住院医师需要同时用双手以协调的方式控制内窥镜和操作工具。因此，为了阐明参与者的行为，这些场景分别用优势手、非优势手，最后用双手通过触觉界面来进行操作。23名住院医师自愿参与了这项研究。在他们执行场景任务时记录了他们的眼动情况。根据这项研究的结果，与其他场景相比，在执行模拟手术模型时，参与者的心理负荷有所增加。因此，可以得出结论，外科住院医师的眼动可以提供有关基于技能任务预期难度水平的见解。这些信息对于合理设计和组织神经内镜手术教学材料，以及更好地指导和评估基于计算机模拟的技能培训环境中学员的进展可能非常关键。
