Using vibrations much like a Morse code, professor Nobuyuki Sasaki has invented a type of cellphone that works in Braille for blind dialers.
Using a Braille keybaord, the phone uses tactile feedback in the form of dual vibrating mechanisms to respond to input and “display” output, the phone makes it easier for those who can’t see to dial numbers correctly.
It’s a cool advancement, and something we don’t think about much. Really, though, as voice recognition gets more advanced, isn’t that going to be the way the blind will use their mobiles?
