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.)
