Visualization of video content viewing history and generation gap

Abstract

　In modern times, there exist a plethora of visual media contents such as tokusatsu series, TV anime, and theatrical films. Some of these contents, such as the Ultra series that premiered in 1966 and the Pretty Cure series that premiered in 2004, have been produced for a long period of time. If one has been residing in Japan from childhood, they are likely to have watched these series. While they can be treated as a common topic among many people, there can be a generational gap in terms of which series or works they have watched and at what age they watched them. As time passes since viewing, memories of the watched contents and the age at which they were watched tend to fade, making it difficult to accurately recognize the generation gap. Therefore, in this study, we develop a system to plot the watched contents on a chronological chart along with the age at the time of viewing, visualizing the temporal progression of acquired information and knowledge. By sharing information between generations, we also aim to address the generation gap.
