Abstract

A shadow implicitly represents the existence of a human or object for various applications in interaction and media art designs. However, it is challenging to generate a natural shadow in artificial for a spatial augmented reality where the conventional approaches ignore the object dynamics and automatic control. In this work, we propose an interactive shadow generation system that creates the interactive shadow of users using a projector-camera system. With the offline processes of human mesh modeling and virtual environment registration, the proposed system rigs the 3D model created by scanning the user to generate the shadow. Finally, the generated shadow is projected into the real environment. We verify the usability of the proposed system and the impression of the generated shadow from our user study.
