Overview of the Extended Reality Continuum for Immersive Learning Experiences

The Extended Reality Continuum is composed of:<br>Augmented Reality (AR)- central experience being the real world, supplemented by superimposed digital information achieved either through a handheld screen or a head mounted display (HMD)<br>Mixed Reality (MR)- Real and virtual worlds are intertwined such that users are able to interact with objects in both the real and virtual worlds<br>Augmented virtuality- central experience being the virtual world, supplemented by information from real world objects<br>Virtual Reality (VR)- fully immersive artificial environment where users have no sense of the real world扩展现实连续体（Extended Reality Continuum）由以下部分组成： 增强现实（Augmented Reality，AR）：核心体验以现实世界为基底，辅以通过手持屏幕或头戴式显示器（Head Mounted Display，HMD）叠加的数字信息 混合现实（Mixed Reality，MR）：现实与虚拟世界相互交织，用户可与现实及虚拟空间中的物体进行交互 增强虚拟性（Augmented Virtuality，AV）：核心体验以虚拟世界为基底，辅以现实世界物体的相关信息 虚拟现实（Virtual Reality，VR）：完全沉浸式的人工环境，用户无法感知现实世界
