Implant Translates Written Words To Braille, Right On the Retina

An anonymous reader writes "For the first time, blind people could read street signs with a device that translates letters into Braille and beams the results directly onto a person's eye." According to the article, "In a trial conducted on a single patient who already used the [predecessor] device, the person was able to correctly read Braille letters up to 89 percent of the time, and most of the inaccuracy appeared when the participant misread a single letter. The user was able to read one word a second."

Re:Why not just use the letter?

Braille is a six-bit binary code. This was done largely because the previous system -- raised type being "read" by fingers -- was slow and inadequate. Whether the input comes through your fingertips or through the optic nerve matters little. If the bandwidth is low, it helps a lot of the content is pre-digitized. That's what Braille does.
