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.
These aren't drug trials here, you don't need a large sample size to determine probable effects. The guy is blind. If he can suddenly read after using this device we can be pretty certain the device is responsible.
We hope your rules and wisdom choke you / Now we are one in everlasting peace
You can't assume blind people are familiar with the alphabet as we see it. They recognize a letter as a dot pattern instead of latin letter. It means 'a' to them be they might never know what 'a' actually looks like.
