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方便， 触觉接触到的信息 可通过可视计算机显示器获得。 页面格式为 可刷新的盲文字符将使视力残疾者 有效参与文字处理、计算机 编程及相关任务。 该器械将增强 现有的辅助工具，如盲文打印机，语音合成， 单线盲文字符输出系统， 内容与格式相关的输出。 盲文字符由可移动的针表示。 每个销 运动是由镍钛诺形状记忆合金丝驱动的 其由电流加热。 这种机制几乎不需要 空间，提供足够的力量，需要适度的力量， 制造成本低。 在第一阶段，建立并测试了一个盲文字符。 相 II研究将旨在构建和评价一个 包含20行字符的原型，重点是 定义用户需求和制造成本。
