Oh, so we're talking about a tablet? Jeez, why not just invent an application? I'm sorry, but we blind individuals carry enough crap around in the first place, we certainly don't need a tablet that just writes Braille and that's it, although I'll admit it's a nice idea.

>> 
>> "Elegant, no?" said Lew. "The solution is so simple, so beautiful. It was

>>

>> 
>> Dharmaraja noted. "They can accommodate users whose fingers are small or
>> large, those who type with fingers close together or far apart, even to
>> allow a user to type on a tablet hanging around the neck with hands opposed
>> 
>> as if playing a clarinet."
>> 
>> "No standard Braille writer can do this," said Professor Charbel Farhat, the
>> 
>> chair of the Aeronautics and Astronautics Department and executive director
>> 
>> of the summer program. "This is a real step forward for the blind."
>> 
>> SHOWING OFF
>> 
>> In a demo, Duran donned a blindfold and readied himself before the
>> touchscreen. He typed out an email address and a simple subject line. Then
>> he typed one of the best-known mathematical formulas in the world, the
>> Burgers Equation<http://en.wikipedia.org/wiki/Burgers%27_equation>, and
>> followed with the chemical equation for
>> photosynthesis<http://en.wikipedia.org/wiki/Photosynthesis> - complex
>> stuff - all as if writing a note to his mother.
>> 
>> For Duran, who has an uncle who is blind, the greatest joy was in seeing a
