A Proposal of Interactive Projection Mapping Using Kinect

Recently "entertainment computing" (EC) technology becomes a hit term in Japan. There is a well-known "projection mapping" in this EC. Projection mapping is a video technique that synchronizes real and video, and the fascinating world view that the fusion of both produces attracts worldwide attention. "Mapping" of projection mapping has a meaning of pasting a material called video on the surface layer of the projection target. In mapping, by giving images such as light and shadow while utilizing information such as the design and unevenness of the object, realistic multi-dimensional feeling and space feeling can be expressed. In this study, we prototyped an interactive projection mapping that changes according to user's movement by projecting to the user. This time we focused on sports like baseball and soccer, and we projected the ball to the user by projection mapping so that we can experience pitching and lifting.
