|A 40-cell Braille reader|
Luckily, science marches on, and North Carolina State University researchers have come up with a way to display 25 rows of text at a time. So Braille readers can backtrack, move forward, and navigate more easily. Naturally this tech is going to make the readers cost more, so the researchers are using magic to fix that problem. No, just kidding. They have two possible ways of fixing it - both of which are outlined in the article.
Reading Braille is an important issue in the blind community. Some people say that blind people can just use speech synthesizers, to read the Web out loud to them (the library where I work uses a Kurzweil system of reading text aloud). However, learning Braille is an important skill for people with sight difficulties. According to the article, 90% of people in this population who have jobs can read Braille, but only 10% of blind children are learning Braille.
