論文アブストラクト：This paper examines the sense of presence, attitude change, perspective-taking, and usability of a split-sphere, first-person perspective 360 degree video about gender inequality, in which people can choose to watch the narrative from the male or female character's perspective. Sixty-seven participants were randomly assigned to watch (1) the video in 360 degree split-view in a head-mounted display, (2) the same film as 180 degree in a HMD, or (3) a flat control version of the video on a laptop. The 360 degree split-sphere increased the viewers' feeling of personal responsibility for resolving gender inequality, desire to rewatch the video, fear of missing out, and feeling of missing the full story. The 180 degree video created the strongest sense of presence, embodiment, and understanding of the character. However, people with greater egocentric projection onto the male character felt less responsible for resolving gender inequality, particularly in the 360 degree split-view.
