原标题：Beyond Simplification: DFT-GEN for Fidelity-Preserving Visual Accessibility in Dyslexia-Friendly Educational Texts
AI 摘要
香港理工大学的研究团队提出了DFT-GEN框架，用于在面向阅读障碍学生的教育文本中保持信息保真度的同时提升视觉可访问性。该框架结合了受保护跨度保留和确定性阅读障碍可访问性控制器（DAC），并在2280个双语考试题目上进行了评估，结果显示在视觉可访问性方面优于对照组，同时保持了任务关键信息。

Beyond Simplification: DFT-GEN for Fidelity-Preserving Visual Accessibility in Dyslexia-Friendly Educational Texts Abstract Dense educational texts impose avoidable reading friction on people with dyslexia, yet generic simplification can delete terminology, task constraints, or source evidence that readers still need. Stakeholder interviews with dyslexic adults and specialists reveal a core tension: reduced burden must not compromise information fidelity. We present DFT-GEN, a stakeholder-inform
