We propose to provide, for non-sighted persons, the convenience of tactile access to the same kind of information that is available via the visual computer monitor. A page format of refreshable Braille characters will enable a visually disabled person to participate effectively in word processing, computer programming, and related tasks. This device will augment existing aids such as Braille printers, speech synthesis, and single-line Braille character output systems by providing tactile output in which content is related to format. Braille characters are represented by movable pins. Each pin motion is actuated by a wire of Nitinol shape-memory alloy which is heated by electric current. This mechanism takes little space, provides adequate force, requires modest power, and is inexpensive to manufacture. In Phase I a single Braille character was built and tested. Phase II research will be aimed at construction and evaluation of a prototype containing 20 rows of characters, with emphasis on defining user requirements and manufacturing costs.

我们建议为失明人士提供便利 触觉访问相同类型的信息 可通过可视计算机监视器获取。 页面格式为 可刷新的盲文字符将使视力障碍者能够 有效参与文字处理、计算机的人 编程和相关任务。 该装置将增强 现有的辅助工具，例如盲文打印机、语音合成和 通过提供触觉的单行盲文字符输出系统 内容与格式相关的输出。 盲文字符由可移动的图钉表示。 每个引脚 运动由镍钛诺形状记忆合金丝驱动 由电流加热。 这个机制需要很少的时间 空间，提供足够的力量，需要适度的力量，并且是 制造成本低廉。 在第一阶段，构建并测试了单个盲文字符。 阶段 II 研究的目的是构建和评估 原型包含 20 行字符，重点是 定义用户需求和制造成本。
