摘要：

依托当前快速发展的虚拟现实技术，以工程图学课程图感培养为目标，将增强现 实技术引入课程教学，开发以移动终端为应用平台的辅助教学系统，将真实场景中的平面视图 与虚拟三维立体模型相结合，通过视觉耦合叠加和增强交互操作突出体验的真实感，搭建起视 图与形体间的以图感意识为桥梁的高效转换通道，提升了抽象三维形体的可接受度。配合课程 讲解和课下辅导，学生能够有意识地强化图感在视图解读中的认知作用，该教学模式和资源的 改革探索将有助于推动新时期工程图学教学的发展。

Abstract:  Supported by the currently rapid development of virtual reality technology, in order to improve the sense of drawing set as the goal in engineering graphics course, the augmented reality technology was introduced into curriculum teaching and auxiliary teaching system on mobile devices as application platform was developed. In this system, the real scene of plane view was combined with virtual 3D models. The coupling and interaction experience reality was enhanced by a high level visual superposition. The sense of drawing can be set up as an efficient conversion bridge between the imaging and three-dimensional solid. By using such bridge, the acceptable degree of abstract three dimensional model and the learning interest were promoted. With the lecture and the guidance after class, students will consciously strengthen sense of figure interpretation in the view of cognitive function. The reform of teaching mode and resource discovery will help to promote the development of engineering graphics education in future.
