Key picking for write-ins -- Vision impaired interface

I've picked out a few things from the discussion I think are most relevant:

> Feedback models other than letter by letter for text entry
> are almost irrelevant to voting systems
> There are voter privacy issues that come up with any interface

Matt Shomphe:

David Mertz

So, do we have some consensus on this?

A standard keyboard using the up/down back/forward arrows for picking
letters from a list of spoken letters heard through the headphones. Can we
make a kind of letter wheel so that the voter could hear a letter and go
back or forward with the arrow keys to find the one they want? If you hear
"a", you could arrow back to get "z" or hit the back arrow 4 times and get
"w" with necessarily hearing "z.....y....x...." if the key is hit rapidly
in succession.

This may or may not be optimal but we don't have to have the perfect system
for the demo. But we need to agree on a way to do it that can be
implemented without too much technical difficulty.

Let's see if we can agree on this so we can move on to menu navigation.
