Android's built-in text-to-speech functions could be leveraged in order to develop a bitcoin app similar to BitcoinSpinner to do what is needed here, and the user could easily control how he hears it by buying a bluetooth earpiece. Wouldn't do much for developing nations, though. Braille sucks, BTW. My wife has a number of visually impaired relatives that would benefit greatly from such an app, and they tend to agree that Braille is broken in many ways. Tactile Morse would be better for the blind in America to learn, if every single elevator built didn't already have Braille markers. And tactile Morse has the additional advantage that it's nearly identical to regular Morse code, so once learned the user could hear his dumber electronic devices using regular Morse code.
To be clear, are you advocating that Ellet should use Morse Code? If that's the case, Matthew should have no problem getting funding.
No, I'm advocating that a dumber device, such as a version of the Bitcoincard, could be used using a piezo speaker & morse. I don't consider this likely, since it's much more likely that a future bitcoin hardware device will be quite modern. Morse would work, but be a bit of a cheap hack, much more likely to occur in a developing nation if Bitcoin takes off before today's smartphone tech trickles down to the rest of the world. Considering that a single rooted & flashed Kindle 2 off craigslist can hold the entire 12 year curriculum of a remote villiage school and do it for far less than that same set of books in print, it's only a matter of time before smartphone tech is common enough that the common man in developing nations can communicate using a several year old (working) smartphone.
