Development of an augmented reality game by extendinga 3D authoring system

In this paper, we describe the development of augmented reality games using the virtools dev 3D authoring system and custom extensions that allows to integrate augmented reality features and advanced interaction techniques. We used this system to create an AR game by extending an existing board game with virtual objects. The concept of predefined high-level building blocks and the visual programming environment supports the iterative design approach and allows to quickly develop and test new game ideas.
