Development of Projection Mapping with Utility of Digital Signage

Recently, Projection Mapping is attracting attention as a new approach for visual expression method. In order to perform large-scale Projection Mapping, multiple projectors are required. In this paper, we propose a new representation technique by various attempts. To determine more impressive visual expression, we have developed Projection Mapping and devised Prodigious Mapping. We have set the projector not to project from many directions, but from one direction. We have been pursuing the possibility that we could use Projection Mapping not only as one of the movie technique but also as a practical approach into a wide range of fields, such as coordination of the shopping mall as regional contribution, transmission of academic contents in the science museum, projection to the historic building to inform the history and culture and so on. We developed the new projection method, "Gem Mapping", specializing for indoor settings. In this method, we make objections made with white boards and set them on a wall inside of a building. We create big gems on the wall by projecting video to the objects. Gem Mapping can set inside the building permanently and reduce the costs. We use touch sensor to detect the motions of people and change images to create interactive Projection Mapping. Gem Mapping is a new advertising media to be used in a lot of commercial facilities as digital signage.
