Abstract: This article introduces the basic principle of AR (augmented reality) technology and the application in various fields. AR renders the virtual objects into the real scenario, which is a complement to realistic environment. Guided by the blended learning theory, the application of augmented reality in the classroom of blended teaching is discussed. Taking the development and demonstration of the operation process of an instance in the high school chemistry teaching as an experimental example, the advantages of AR in teaching are demonstrated, which provides a reference for the application of AR in the field of teaching.
Key words: augmented reality; blended learning; blended teaching; application of AR

增强现实(augmented reality,AR),也被称为混合现实,是在虚拟现实技术(virtual reality,VR)基础发展而来的一项技术。增强现实是把真实环境和虚拟现实的景象叠加起来,在同一个画面或空间同时存在,并强调虚拟对象与真实世界物体的交互。虚拟现实技术则注重运用计算机创造一个人机交互的3D虚拟空间,为使用者提供关于视觉、听觉、触觉等感官的模拟,用户完全沉浸在一个虚拟的合成环境中,无法看到真实环境。增强现实能够把计算机虚拟信息(物体、图片、视频、声音等)融合在现实环境中,用户观察的真实场景与虚拟物体共存一个视觉感知空间,把现实世界丰富起来,对现实环境进行了更逼真的补充,增强了用户对真实环境的理解。增强现实的使用可比喻成在用户的现实世界里开了个窗口,或者将来视角足够大的时候,把呈现在我们面前的现实世界做一个叠加的、真实的注解。VR与AR两者由于技术原理不同,各自的应用领域不尽相同,两者都致力于塑造具有真实感的感官输入、交互的环境。……
