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."
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.
How is the Riemann zeta function like Trump rallies? Both have an endless number of trivial zeros.
If you read a bit further in the article, you'll note the part you quoted is the description of the PREVIOUS model device.
The CURRENT model, which the summary is talking about, being an improvement to the original, CAN read street signs and at one letter a second.
I use caps since you don't obviously don't read everything presented :P
Now THIS is a retina display!
Circumcision is child abuse.
i think we need a double blind study before we can be certain.
