In early stages of film or animation production, storyboard is used to visually describe the outline of a story. Drawings or photographs, as well as the texts, are employed for character / item placements and camera pose. However, commercially available storyboard tools are mainly drawing and editing tools, not providing functionality for item placement and camera control. In this paper, an Augmented Reality based storyboard tool is presented, which provides an intuitive and easy-to-use interface for storyboard development. Using the presented tool, non-expert users may compose 30 scenes in his or her real environments through tangible building blocks which are used to fetch corresponding 3D models and their pose.
