ScienceDaily (Mar. 29, pancreatitis 2010) — Imagine if your computer only allowed you to see one line at a time, no matter what you were doing — reading e-mail, looking at a Web site, doing research. That’s the challenge facing blind computer users today. But new research from North Carolina State University is moving us closer to the development of a display system that would allow the blind to take full advantage of the Web and other computer applications.
Right now, electronic Braille displays typically only show one line of text at a time. And they’re very expensive,” says Dr. Neil Di Spigna, a research assistant professor at NC State and co-author of a paper describing the research. In order to develop a more functional, and affordable, tool that would allow the blind to interface with their computers, Di Spigna and his colleagues are working to develop a full-page, refreshable Braille display. Braille uses a series of raised dots to represent letters and numbers, allowing blind people to read.
Such a display would also translate images into tactile displays, effectively mapping pixels in an image and allowing the full-page Braille display to represent the images as raised dots.
