Hello boacosta,

A friend sent me this article on touch screen and cell phone and I
thought others would be interested in seeing this too.

    "In braille, a character is made up of six dots laid out on a two by
three matrix -- not something that can really be conveyed using
capacitive touchscreen technology. Working with a Nokia 770 Internet
Tablet, researchers in Finland have developed a method for
piezoelectric touchscreen devices that uses a single pulse of intense
vibration to convey a raised dot, and a longer vibration made up of
several weaker pulses to represent a missing dot -- spelling out
letters that can be easily read by touch. It took a while for
volunteers to get used to this method, but once they had they were
able to read a character in as little as 1.25 seconds. Now that they
have letters down, the team is moving on to words and sentences --
with an eye towards developing text-to-braille software sometime in
the future."
