第一に，W3Cに分かち書きのためのCSS拡張を提案し，承認を得てCSS Text Module Level 4に追加．Web Platform Testプロジェクトでテストスイートを開発した．第二に，分かち書き位置を自動決定するプログラムを開発し，無料で公開した．第三に，プリントディスアビリティに応じた日本語組版の切替え可能なEPUB文書例を作成し，公開した．第四に，評価実験により分かち書きの有無や縦組・横組の選択についてデータを収集した．分かち書きには個人差があり，統計的な有意差が難しい．縦組に苦手な児童もいるが有意差は見いだせていない．文節改行については有意差が見られる見込みである．
First, we proposed CSS extensions for Japanese text segmentation to the W3C and integrated them into CSS Text Module Level 4. We also developed a test suite as part of the Web Platform Test project. Second, we created a program that automatically determines text segmentation positions and made it available for free. Third, we produced and released EPUB document examples that offer different Japanese layout options based on print disability characteristics. These options include ruby annotations (full ruby, partial ruby, no ruby), Japanese text segmentation (with or without explicitly specified segmentation points), and vertical or horizontal writing. Fourth, we conducted evaluation experiments. Regarding text segmentation and horizontal/vertical writing, there were variations in readability among individuals, which posed challenges in establishing statistical significance. However, there is potential for significant findings concerning line breaking after text segmentation.
