• 論文抄録 / 内容記述: We developed Mixed Reality (MR) contents that reconstructed the ancient capital of Asuka-Kyo and applied a fast shading and shadowing method that used shadowing planes. The proposed shadowing method can support both dynamic changes of illumination and movements of user's viewpoint. We also propose an effective foreground segmentation and shadow removal method to solve the occlusion problem in outdoor MR. The impression evaluation test of Asuka- Kyo MR Contents confirmed that shading and shadowing increased the audience's favorable responses to the evaluating factors of "Realistic," "Spectacular," and "Entertaining." And the subjective evaluation experiment showed that displaying these contents increased the audience's knowledge of both Asuka-Kyo and MR technologies.
