摘 要：目前远程教育以其空间和时间的便捷性，受到了越来越多的关注和参与。然而在理工类远程教育课程中，由于内容往往比较抽象复杂，立体度高，使用传统的二维素材学习往往导致学习者接受、理解较为困难，造成学习效率低下等问题。利用基于移动设备的增强现实技术，可以将三维实景融入到抽象的二维素材中，使教学内容生动形象地展现在学习者面前，有助于提高学习者的学习效率和兴趣，使学习者能够更充分地掌握学习内容。本文就增强现实技术如何应用于远程教育《机械设计制造》课程进行具体阐述。

Research on Application of Augmented Reality Technology in Science and Engineering Courses of Distance Education

Luan Tingting Yu Chao Yang Jiaqi

Abstract：At present， distance education has received more and more attention and participation due to its space and time convenience. However， in the science and engineering distance education courses， as the content is often more abstract and complex， and the three-dimensionality is high， the use of traditional two-dimensional materials for learning often leads to difficulties for learners to accept and understand， resulting in low learning efficiency and other problems. With the use of augmented reality technology based on mobile devices， three-dimensional real scenes can be integrated into abstract two-dimensional materials， so that the teaching content can be vividly displayed in front of learners， which helps to improve the learning efficiency and interest of learners， and enables learners to morefully grasp the learning content. This article specifically elaborates how augmented reality technology is applied to the distance education of "Machinery Design and Manufacturing" course.

Key words：distance education， mechanical design and manufacturing， augmented reality technology， mobile devices

1 引言

增强现实（augmented reality，AR）技术是于1990年由Tom Caudell首次提出的，是在虚拟现实（virtual reality，VR）的基础之上产生的。它对真实环境中的信息进行三维注册，将计算机生成的虚拟信息叠加应用到真实世界，利用传感技术和显示设备将虚拟信息和真实世界统一在一个画面或空间内，从而实现对现实世界的增强，达到超越现实的感官体验[1]。1997年Azuma等研究人员认为AR应该包含3个准则：虚实结合、实时交互和三维注册[2]。到目前，随着5G等技术的快速发展，AR技术已经逐步具备了从研究为主转向实际应用的条件，在游戏、旅游、文化、教育、军事、工业等领域都开始逐步崭露头角。由于增强显示技术的三维性、交互性和趣味性，能够解决教育行业中存在的诸多难题，因此该技术在教育方面的应用受到越来越多的关注。……
