Recently, we can very easily and frequently find vection scenes in Japanese movies and animation films. However there had not been a database for them. Our purpose of this study was to make a database of vection scenes in Japanese movies and animations and provide VR psychologists all over the world with that database. We checked many movies and animations and found 30 vection scenes. We uploaded that information on our web site (senotake.jp). We also conducted a psychological experiment to assess vection strength obtained by those scenes and compared them to perceived vection obtained by a normal and simple vection stimulus (the standard stimulus) that had been used in our previous vection experiments. The results showed that perceived vection induced by those scenes were nearly the same strength as that of vection induced by the standard stimulus. We also revealed some effective and inefficient techniques of scene presentations in this study. Finally we calculated various image statistics and compared them to vection strength. That analysis revealed that a scene that contained more changes could induce stronger vection. We sincerely hope that this study can be the bridge between experimental psychologists and contents creators and developers.

We report a new method of facilitating illusory self-motion perception (vection). Participants held either a full glass of water or a half glass of water while experiencing vection, and were instructed not to spill any of the water. Vection strength was indexed by its latency, duration, and magnitude. Results showed that vection was enhanced in the full glass of water condition. We want to name this method of vection facilitation “full-glass-water method”.

We interviewed seven professional creators of visual images, on “vection.” Vection is an illusion of a visually induced self-motion perception. In Seno-Lab, previously we conducted three approaches to bridge between scientific psychologists and creators of visual images, i.e., vection-scene-database in Japanese animations, movies of vection stimuli used in the previous scientific articles and the movie of a scientific introduction of vection. Seven professional creators evaluated our approaches. We got a lot of hints for the further developments of our approaches from the results of these interviews. In the seven, three contemporary artists, one movie director, two designers and one photographer were included. They suggested the future tasks for our approaches to bridge the two different business fields.
