E-Learning by Classroom Functionality Extension Based on Table Top Interface

在本研究中，纸顶界面（PTI）的建议和发展，融合了纸张和数字学习材料，以支持笔记在课堂上。PTI系统使用基于视觉标记的AR（增强现实）技术，并将数字学习材料投影到笔记本的相应页面上。通过与普通笔记方式的比较，发现PTI系统并不逊色于普通笔记方式，而且不会降低学习效果。此外，PTI系统的交互性多样化，以控制学习材料的内容（例如，例如，在一个实施例中，隐藏并绘制视觉标记。

In this study, Paper-Top Interface(PTI) was proposed and developed, which fused paper and digital learning material to support note-taking in a classroom. The PTI system uses a visual-marker-based AR(Augmented Reality) technology and projects a digital learning material onto the corresponding page of a notebook. In comparison with common note-taking styles, it was revealed that the PTI(system) was not inferior to the common styles and did not decrease learning effect. In addition, interactivity of the PTI system was diversified to control the content of learning material(e. g., hiding and painting the visual marker.)
