Isar: An Authoring System For Interactive Tabletops

Despite more than three decades of research in augmented reality and shown positive effect of AR in educational settings, we still don't witness spread of this technology in the schools. Complex technology and limited educational content are among the reasons for this absence. Authoring systems can play a positive role in introduction of AR into the school settings. In this paper we introduce ISAR, a domain-independent authoring system for a camera-projector based interactive tabletop. ISAR allows teachers to create learning content and define interactions for the tabletop themselves, without the need for programming, and hence reduces the entrance barrier of educational practitioners for experimenting with augmented reality and tangible interactions.
