High-Definition Digital Display Case with the Image-based Interaction

This paper proposes a high-definition digital display case for manipulating a virtual exhibit that has linking mechanisms. This technique enhances the understanding of dynamic exhibits. It is difficult to construct interactive contents of dynamic virtual exhibits, because measuring the mechanism invokes the risk of an exhibit's deterioration, and it takes tremendous efforts to create a fine spun computer graphics (CG) model for mechanisms. Therefore, we propose an image-based interaction method that uses image-based rendering to construct interactive contents for dynamic virtual exhibits using the interpolation between exhibit pictures with a number of deformational conditions and viewpoints. Using this method, we construct a high-definition digital showcase and exhibit the interactive content at a museum to evaluate the availability of our system.
