We are conducting research on super multi-view 3D video systems for highly realistic communications. We developed a glasses-free auto-multiscopic 3D display, and a 3D capturing system to capture live real moving objects. Since the spring of 2013, we started several field experiments in a public space with this system. The place is GRAND FRONT OSAKA, located on the north side of JR Osaka station. In this study, we report on the analysis of audience's behavior and audience's evaluation of the 3D contents on an auto-multiscopic display, in the public space.
