Microfluidic technology for a full-page braille and graphical tactile display

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.
