Outline of Final Research Achievements

Captions and subtitles are essential to information accessibility for hearing-impaired people, deaf people, and elderly people who have difficulty hearing audio information to understand the information of video content. Besides, there are many cases in which captions are displayed in public spaces that cannot produce sound, and there is a high demand for people with normal hearing for subtitles. The Ministry of Internal Affairs and Communications supports the captioning rate, but the issue was to consider the "quality" of the caption design, such as the ease of viewing and comprehension. Therefore, in this study, we conducted a study of video cognitive characteristics to quantitatively investigate the effect of captioning design on the visibility and content understanding of video and captions not only in the captions themselves but also in the video. We have established a caption evaluation method based on cognitive characteristics and developed a captioning design evaluation tool.

Academic Significance and Societal Importance of the Research Achievements

これまで経験や勘に頼って決められていた字幕のわかりやすさの評価を、映像認知特性に基づいて科学的に定量的に分析する手法を確立し、かつ、その複雑な分析を自動化し、字幕の制作者や字幕の制作の依頼者が、完成した字幕が視聴者にわかりやすいかどうかを表示する字幕デザイン評価ツールを開発した。これによって、適切なコストと安定した品質の字幕の供給を支援し,バリアフリー化の普及を促進することができる。字幕やそれが重畳される映像がどう見えているか、を科学的に調べた知見は、スマートグラスのようなAR(Augmented Reality)技術などの次世代デザインの基盤知見としても学術的意義が大きい。
