增强现实技术支持下的儿童虚拟交互学习环境研发

增强现实环境中的学习注重虚拟与现实的结合,通过在现实环境之中叠映虚拟三维场景信息,让学习者使用电脑或移动终端在虚实融合的学习环境中交互学习。文章在精要阐述增强现实技术可为儿童构建四种类型的虚实结合的交互学习环境的基础上,以交互式儿童多媒体科普电子书为例,论述基于增强现实的儿童虚拟交互学习环境的结构功能、开发工具、三维模型和标志物的设计及制作、增强现实引擎的实现,以及阅读机理与流程。

The Development of Augmented Reality Virtual Learning Environment for Children on Augmented Reality

The learning in augmented reality environment that is emphasis for virtual-real fusion display. By tracking virtual 3Dseene extrinsic parameters and intrinsic parameters in real time, and in which learner study by the computer or mobile terminal unit. Children are tittupping who learn knowledge with amusement Therefore Children are adapted deeply to the Augmented Reality Virtual Learning Environment. This dissertation comprehensively introduces the conception, characteristics and an application of augmented reality. We analyze the architecture of genera augmented reality system, it is key technologies and the functions of four important modules, Then we explain in details of the function, applications and implementation of key technologies and tools for the Augmented Reality Virtual Learning Environment for Children.
