增强现实学具的开发与应用——以“AR电路学具”为例

The Development and Application of Augmented Reality Learning Aids ---The Case Study of AR Circuit Learning Aids

增强现实学具将虚拟信息融入真实学习环境，使信息的呈现既能与真实物理空间对应，又不受学具真实属性的约束，弥补了传统学具的诸多不足。增强现实技术融入学具的开发，能够向学习者提供降低认知负载的知识访问接口，从物理感知、认知、情境三个维度拓展了学具的应用。该文通过“AR电路学具”的开发与应用，介绍了增强现实学具需求分析、设计、开发、调试与分布的完整流程，给出了相应的技术选型方案和开发实施路线，提供了实际应用方案。增强现实学具的研究可以强化学具的助学功能，拓展学具的应用范围，丰富教学工具的表现形式与互动手段。

With virtually unlimited expressiveness and ability to keep the virtual world aligned with the real， augmented reality (AR) learning aids overstep the limitations of their traditional counterparts. The introduction of AR into learning aids expands their application field in the sense of physical， cognitive， and contextual dimensions， and thus supplements knowledge access with an interface that features in reduced cognitive load. Through the case study of “AR Circuit Learning Aids”，this paper explained the whole process of AR learning aids implementation， provided its technical selection and implementation routes， and gave correspondent usage scenarios. The study showed that AR learning aids are more expressive and interactive， and thus have a wider application field. This study yielded a scalable circuit learning aid， and gave light to the application of AR in the classroom as learning aids.
