I sure hope they are successful as tactile displays to
this point are simply outrageously expensive and I think most of
that cost is due to the nature of the technology. So far, each
dot in a tactile display is some sort of mechanical assembly
that requires precision manufacturing and individual attention
for want of a better word. Normal print displays don't have
individual light sources carefully soldered in to place but
instead are matrices in which each pixel is a square or
rectangle formed by the intersection of horizontal and vertical
lines.
The electronics to control a Braille display have been
with us for decades now, but the mechanics of actually raising
and lowering each dot are troublesome when it comes to cost and
precision.
It will be interesting to see how they solve this
problem if they are successful.
