Abstract

The Boston-based National Braille Press has established a Center for Braille Innovation (CBI), whose mission is to research and develop affordable braille literacy products. The primary focus has been to facilitate the development of dramatically lower cost electronic braille display devices, and the much-sought-after "Holy Braille" of a full-page electronic braille display. Developing affordable new braille technologies is crucial to improving the extremely low braille literacy rate (around 12%) of blind students. Our CBI team is working to aid developers of braille technology by focusing attention and resources on the development of the underlying braille actuator technologies. We are also developing braille-related information resources to aid braille display developers. The CBI braille requirements summary (available through the NBP website (http://www.nbp.org) is one of these resources. The braille specifications include braille dot dimensions, spacing, displacement, lifting force, and response time requirements. In addition, mentoring, helping to evaluate new braille display ideas, and openly sharing braille display technology are all part of the activities of the NBP braille innovation team. NBP has expanded the CBI project with domestic and international partners including the China Braille Press, World Braille Foundation, National Federation of the Blind, American Printing House for the Blind, American Foundation for the Blind, and many university and research partners.
