Blind Patient Reads Words Stimulated Directly Onto Retina: Neuroprosthetic Device Uses Implant to Project Visual Braille. ScienceDaily. November 22, 2012.
The device described in this article is a small camera mounted on glasses coupled with a processor to translate signals into electrical stimulation which are in turn transferred to a microchip with electrodes which are implanted on the retina. Now implanted in over 50 patients, many of these blind individuals can now see color, movement, and objects. This is the first time streamed braille onto a blind person's retina.
