In conventional virtual reality systems, users usually do not perceive and recognize the experience as reality. For example, users of a virtual disaster simulator know, consciously or unconsciously, that the presented disaster is not real, which inherently limits the training effect. To make the virtual experience more believable, we propose a novel real-virtual transiton technique that preserves the sense of “conviction about reality” in a virtual environment. This is realized by spatio-temporal smooth transition from the real environment to the virtual environment with omnidirectional video captured in advance at the user’s position. Our technique requires less preparation cost and presents a more believable experience compared to existing transition techniques using a handmade 3D replica of the real environment. In this article, reported are the concept of our technique, a prototype system and a preliminary user study that has shown the effectiveness of the technique.
