We present an interactive exhibition concept built on existing physical wall panels in a museum. By combining the unique exhibition contents with various rendering and interface techniques, we create immersive contents that have two-way communication and multi-modal feedback as key features to provide engaging experiences. We apply our interactive panel concept to a mummy exhibit in a natural history museum in Korea and demonstrate its effectiveness. The final goal of this project is for it to serve as a platform for virtual museums to provide an opportunity to expand offline museums to an online experience.
