The discrete anatomy of the eye's intricate oculomotor system is conceptually difficult for novice students to grasp. This is problematic given that this group of muscles represents one of the most common sites of clinical intervention in the treatment of ocular motility disorders and other eye disorders. This project was designed to develop a digital, interactive, three-dimensional (3D) model of the muscles and cranial nerves of the oculomotor system. Development of the 3D model utilized data from the Visible Human Project (VHP) dataset that was refined using multiple forms of 3D software. The model was then paired with a virtual user interface in order to create a novel 3D learning tool for the human oculomotor system. Development of the virtual eye model was done while attempting to adhere to the principles of cognitive load theory (CLT) and the reduction of extraneous load in particular. The detailed approach, digital tools employed, and the CLT guidelines are described herein.
眼睛复杂的动眼系统的离散解剖结构对于新手学生来说在概念上很难理解。鉴于这组肌肉是治疗眼球运动障碍和其他眼部疾病时临床干预最常见的部位之一，这就成了一个问题。该项目旨在开发一个动眼系统肌肉和颅神经的数字交互式三维（3D）模型。3D模型的开发利用了可视人项目（VHP）数据集中的数据，并使用多种形式的3D软件对其进行了优化。然后将该模型与虚拟用户界面配对，以创建一种用于人类动眼系统的新型3D学习工具。虚拟眼模型的开发是在试图遵循认知负荷理论（CLT）的原则，特别是减少无关负荷的情况下进行的。本文描述了详细的方法、所使用的数字工具以及CLT指南。
