Transmission of existence by retro reflective projection technology using handheld projector

Our research aims to enable persons to communicate remotely with numerous participants while moving around freely in public spaces. To achieve this goal, we developed a novel remote communication system based on a mutual telexistence master-slave system. In this paper, we propose a system that transmits the operator´s sense of existence to the participant using retro-reflective projection technology and a handheld projector, which solves the problem of a limited sense of the surroundings. Although stereoscopic presentation by motion parallax did not occur in this study, this system was expected to give the participant a stereoscopic view via the surrogate robot using a handheld projector.
