David Pankhurst, author of the blog Utopia Mechanicus, has
designed the Refreshable Braille Display, which will help the
visually impaired use their computers and read content off of
the Internet much more easily. According to Pankhurst, typical
Braille display devices cost about $7,000 -- much too expensive
for most blind people. His solution is a new device, the
Refreshable Braille Display -- which he calls 'Audrey,' after
his mother -- that will display computer data on a small center
window. Braille letters are displayed on a small 3x2 grid
underneath the user's fingers, describes TechNewsDaily. By using
less materials and simplifying the design, Pankhurst has managed
to design the Refreshable Braille Display so that it is low-
cost. In fact, he estimates that a 40-character display will
cost only about $200 to make. Currently, Pankhurst is trying to
raise $1,500 on IndieGoGo to build prototypes of the device and
start actual production. Affordable Braille Displays 1,151
