The blind may have a phone to call their own, thanks to Nikko Van Stolk and his 'Tactile Phone.' The Tactile Phone is an amazing concept phone that uses electric pulses to simulate braille onscreen.
The Tactile Phone would work like any other phone, except for the fact that every menu button would be written in braille. I for one think this is an awesome concept. It would give the blind all the benefits of a cell phone that those of us with sight take for granted. Text messaging, I'm talking to you.
