Outline of Final Research Achievements	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.
