Abstract
Vection is an illusion of self-motion perception. Recently, vection is utilized in various places, e.g. amusement parks, movies, VR environments, and Games as a digital content. On the contrary to the vection as a digital content, we newly focused on vection as an analogue content. We made a picture book of vection and evaluated it in this study. For making a picture book, we first surveyed the history of vection from 19 century to mid 20 century and knew that there are various analogue contents of vection in the past. In a pilot study, we confirmed that four types of static visual illusions invented by Prof. Akiyoshi Kitaoka that could induce vection. We chose the best illusory static image that could induce enough strong vection and made a picture book based on that illusory image. Twenty-five couples of a parent and a child read that picture book and we recorded those whole behaviors of those couples. There were three conditions in the experiment of the picture book. First, a picture book with self-motion illusion. Second, a picture book without self-motion illusion and as the third condition, a picture book with self-motion illusion with an instruction “this is a picture book of a self-motion illusion”. The time consumed in the page of the self-motion illusion was larger in the condition of self-motion illusion with the instruction. Also, the uttered words related with the self-motion perception were increased in this condition. Thus, we could confirm that vection was highly induced in the condition of self-motion illusion with the instruction. We found the high possibility of the picture book of vection, i.e. the high possibility of vection as an analogue content, even though there should be a lot of improvements.
