<DIV>3/31/2009 9:19 PM<BR><BR>Hello boacosta,<BR><BR>A friend sent me this
article on touch screen and cell phone and I<BR>thought others would be
interested in seeing this too.<BR><BR> "In braille, a
character is made up of six dots laid out on a two by<BR>three matrix -- not
something that can really be conveyed using<BR>capacitive touchscreen
technology. Working with a Nokia 770 Internet<BR>Tablet, researchers in Finland
have developed a method for<BR>piezoelectric touchscreen devices that uses a
single pulse of intense<BR>vibration to convey a raised dot, and a longer
vibration made up of<BR>several weaker pulses to represent a missing dot --
spelling out<BR>letters that can be easily read by touch. It took a while
for<BR>volunteers to get used to this method, but once they had they
were<BR>able to read a character in as little as 1.25 seconds. Now that
they<BR>have letters down, the team is moving on to words and sentences
--<BR>with an eye towards developing text-to-braille software sometime in<BR>the
future."<BR><BR><BR><A
