Researchers to Demonstrate Their Solution for Cheaper Braille Displays
at Chicago Haptics Conference

Stop us if you've heard this one before. A team of researchers are
developing a multiline braille display that could dramatically reduce
the cost and increase braille literacy. This isn't a rerun, rather
another in a growing list of projects aiming to combat the fall of
braille adoption in recent years. Sile O’Modhrain and Brent Gillespie,
two researchers from the University of Michigan will present their
findings at the World Haptics Conference in Chicago on Tuesday.
According to an article from the Economist, The screen of the device
includes a grid of pins the diameter of Braille dots. Normally, the
tops of these pins are flush with the screen’s surface. When needed,
though, they can be pushed upwards to create patterns representing
Braille symbols. This is possible because each pin rests on a
silicone-rubber membrane that sits above a small cavity. The cavity
is, in turn, connected to a tiny pneumatic line and valve. When air is
blown through the valve into the cavity, the membrane balloons up,
pushing the pin above the screen’s surface."
The researchers anticipate that a display the size of a tablet, with
26 lines of 40 cells each, could be sold for under $1,000.
