Our purpose is to construct a new type interactive attraction which detects the user’s hand actions as triggers in a multi-participated mixed reality environment. “BLADESHIPS” is a game in which players compete with each other controlling virtually expressed belt-shaped flying objects, which are called “ships”, in the real environment, trying to drive each other hit real/virtual obstacles. For the purpose of reproducing subtle and spatially varying material properties of the real object, we use a 3D scanner and a high-resolution camera.
