学龄盲童的盲文识字率急剧下降，部分原因是制作带插图的盲文页面仍需要专业软件和受过培训的劳动力。我们提出了Tact，一种基于浏览器的流程，可将口述或输入的故事创意转换为可打印的盲文，并配有匹配的凸起触觉插图，无需账户或强制费用，且支持离线路径。本文记录了该系统的工程历史：其明眼操作员的伦理模型；消费级熔融沉积建模的硬件原理；物理盲文几何与打印机校准；本地、托管和备用语言模型路径；确定性的一级盲文翻译器；经过验证的页面布局和分页；一个包含93种手绘触觉插图的库；以及为语音优先界面设计的合成音效。我们报告了工程验证、伦理承诺、局限性以及系统为真正的盲人和低视力读者做好准备所需的工作。
英文摘要
Braille literacy among blind school-age children has fallen sharply, in part because producing illustrated braille pages still requires specialized software and trained labor. We present Tact, a browser-based pipeline that converts a spoken or typed story idea into printable braille with a matching raised tactile illustration, without an account or mandatory cost and with an offline-capable path. The paper documents the engineering history of the system: its sighted-operator ethical model; hardware rationale for consumer fused-deposition modeling; physical braille geometry and printer calibration; local, hosted, and fallback language-model paths; a deterministic Grade 1 braille translator; verified page layout and pagination; a 93-shape hand-drawn tactile illustration library; and synthesized sound design for a voice-first interface. We report engineering verification, ethical commitments, limitations, and the work required before the system is ready for real blind and low-vision readers.
