【摘要】 随着5G+XR+AI等新技术不断影响并渗透学习空间,突破了以往平面视觉的极限感知,全面开启着三维体验与交互新阶段,逼真的三维虚拟动态显现与沉浸式体验逐步成为一种常态。数字孪生技术作为一种在信息虚拟世界刻画物理世界、仿真物理世界、优化物理世界、可视化物理世界的全新技术,将AR、VR和MR三者之间的界限打破,并进行有效融合,它集5G、大数据与智能技术于一体,带来了全新的即生式、移动式、智能化、镜像化、全息态等体验模式。随着算力、联接和显示技术的革命性升级,推进着数字世界和物理世界的相互融通并不断进阶,共同打造出具有"可视化三维学习空间"形态特征的全息课堂。基于全息课堂的发展脉络及技术构成,初步勾勒了全息课堂的模型框架,归纳其特征形态。并通过当前一些相关应用案例的分析,可进一步探究未来全息课堂的应用场域和发展趋势。基于全息课堂的前瞻性研究,对有效促进"智能+"时代新技术赋能下的学习空间、学习方式的变革与重构,具有重要意义。更多还原

【Abstract】 As new technologies such as 5 G+XR+AI influence and penetrate the learning space constantly, the ultimate experience of two-dimensional vision is going to be broken and the new era of 3 D experience and interaction will be initiated. Realistic 3 D virtual dynamic display and immersive experience will become a normal gradually. As a completely new technology to portray, simulate, optimize and visualize the physical world in the information world, digital twin, a blend of 5 G, big data and intelligent computing, integrates AR, VR and MR effectively by breaking the boundaries among them and brings a totally new experience model of present generation, mobility, intelligence, mirror, holography, etc. It will create a holographic classroom with the form of "Visualized Three-Dimensional Learning Space" with the advanced integration of the digital and the physical world, the revolutionary upgrading of computing power, connection and display. The model framework of the holographic classroom has been sketched, and its characteristics and application cases have been summarized by sorting out the development and technical structure of holographic classroom. The application field and development trend of holographic classroom can be further explored by means of analyzing some application cases. It has an important significance for the advanced research of holographic classroom to promote the transformation and reconstruction of learning space and learning methods under the empowerment of new technologies in the era of intelligence plus.更多还原
