NBP Non-Profit Mission Values To be a world leader in producing high quality, affordable, braille materials To develop innovative technologies that support braille literacy for blind and visually impaired children and adults. Provide access to information that empowers blind people to actively engage in work, family, and community affairs. Provide the tools to support braille literacy

17
Challenges of Assessments for BVI Standardized assessments are limited for students using braille and tactile graphics. Braille displays show only one line, and cost thousands of dollars. No affordable method for displaying a digital tactile graphic exists. Eliminating certain test items b/c of ineffective technology or cost. (When assessments go digital- must include tactile graphic output also) NBP recognized the immediate need for a “tablet” for the blind that can do braille and real-time digital output of tactile graphics and images.

Refreshable Braille Displays $5500
19
Center for Braille Innovation NBP is researching technology solutions for braille and tactile graphics: electrostatic haptics, micro-fluidics, SMAs EAPs. b2g: 20-cell portable refreshable braille computer. Ideal: A full-page braille and tactile graphic tablet. Primary Collaborations: M.I.T., University of Michigan, Northeastern University, Disney Research Lab.

Full Braille Page Prototype Template = 25 rows by 40 cells
23
Factors to Consider in Design: Challenges in the development of electronic tactile graphics—electronic media have never been tested. Material durability, cost, ease of production We need to collaborate, and develop STANDARDS for 3D electronic tactile graphics. –IMLS 3D Printing started last week Ability to digitally render points, lines, textures, height, possibly even color for low vision. We need to develop the ability to manipulate tactile graphics in real-time like a tablet. Will there be a relearning of tactile skills based on the mode of delivery? Tactile exhaustion/desensitization from interpreting electronic graphics?
