Afterglow Projection: Virtual Information Projection Method to Real Environment using Pico Projector in Mixed Reality

Projection-based mixed reality (MR) is a method of superimposition that projects virtual information on real environment using a projector. In previous studies, a method using a pico projector as an operation device has been proposed. However, the projection range and the continuity of information presentation are limited. In this research, we replace the projection of the pico projector with a ceiling projector installed in the environment and leave it in place. In this manner, a plurality of virtual information is realized simultaneous with the continuous presentation to the real environment.
