A nice story here about a blind boy in India who has developed a software program called Brailleface, which converts braille commands into Devanagari script.

Assistive technology like screen readers which read electronic text out loud have blasted apart barriers between the blind and the sighted.

Visually impaired computer engineer Avinash Singh says "braille was like a code that only the blind understand. Computers have made us part of the mainstream.

"Now if it's MS Word, the platform is the same, only the interface is different, we can all access the same thing - sighted person through eyes, we through screen reader, this was not possible before," Singh said.

As technology becomes a part of our everyday world visual disability becomes less limiting.
