We don't give much thought to deaf users of phones, but Pratt Institute student Suhyun Kim has worked hard on this stunning Visual Sound concept, which converts voice to text and vice versa.
 
The scroll-like device has a touchscreen for text to be typed in, which then gets converted to voice for the other person on the line, whose audio then turns into text for the deaf user of the phone to read. If the Visual Sound concept ever got put into production, I'll be one of the first to snag one—not only does it look great, but it might help when phoning from noisy locations, as I'm prone to do
