项目摘要

PROJECT SUMMARY/ABSTRACT The goal of this SBIR project is to deliver a multiline refreshable braille and tactile graphics display to the U.S. market. Our envisioned product is a tablet-like device that enables new forms of touch-in, touch-out interaction between blind people and braille and tactile graphics. Thousands of tiny tactile pins in a grid at braille spacing will be selectively and interactively raised on a multi-touch sensing surface. Our device will play a critical role in establishing equity in information access for blind people, particularly in education. It will reduce the reliance on hardcopy and static, physical media that currently limit a blind student’s independence and success. NewHaptics has developed microfluidic technology that allows a small number of electronic valves to individually address and control the thousands of actuators and moving pins in a low-cost and highly manufacturable product. Fluid-based circuits in a tiny soft silicone chip are employed to raise and lower bubble actuators using a one-to-many conversion between an electronic valve and bubbles. Our product will enable true digital interaction using the sense of touch and enhance the quality of life of blind Americans by improving opportunities in education, and ultimately their employment success and independence.

项目概要/摘要该 SBIR 项目的目标是向美国提供多行可刷新盲文和触觉图形显示器。我们设想的产品是一款类似平板电脑的设备，可实现新形式的触摸输入、触摸输出交互。盲人与盲文和触觉图形之间的网格中的数千个微小的触觉针以盲文间距排列。将有选择地、交互式地在多点触控传感表面上凸起，我们的设备将在其中发挥关键作用。为盲人建立公平的信息获取渠道，特别是在教育方面，这将减少对盲人的依赖。目前，硬拷贝和静态物理媒体限制了盲人学生的独立性和成功。 NewHaptics 开发了微流体技术，允许少量电子阀以低成本和高可靠性单独寻址和控制数千个执行器和移动销可制造的产品采用微小的软硅胶芯片中的流体电路来升高和降低气泡。我们的产品将使用电子阀门和气泡之间的一对多转换来实现执行器。使用触觉进行真正的数字交互，并通过改善美国盲人的生活质量教育机会，最终实现就业成功和独立。
