It would work, but perhaps we could get close enough without it. We surely 
should be able to provide feedback about the location of certain keys either 
using the vibrator or using sound. We could even consider make the phone say 
what a button means, although i'm pretty sure most blind will manage with a 
basic 'here is a button' and 'this is five' indication once they know the 
But a specialized ui for the blind is an interesting idea. The funny thing is 
we could just leave display of and increase batterylife.
