Gee Whiz. Why not?

World’s first Vibrating Braille cell phone developed in Japan:

A former teacher at a school for the blind and a professor from Tsukuba University of Technology have developed a cell phone that sends out vibrations representing Braille symbols to enable people with sight and hearing difficulties to communicate.

The phone, reportedly the first of its kind in the world, was created by 73-year-old former teacher Sadao Hasegawa, Tsukuba University of Technology professor Nobuyuki Sasaki and other developers. When a caller pushes numbers on the keypad corresponding to Braille symbols, two terminals attached to the receiver’s phone vibrate at a specific rate to create a message.
