As long ago as 1983 Douglas Maure AFB New York presented a paper to
First Meeting of the International Symposium on aps and Graphics
for the Visually Impaired, In Washington DC. His paper discussed a
prototype 16,000 pin electro-mechanical device, doing the same
function as the German device understood to be selling for around
$40,000. Pizo electric cells functioning as in Braille displays have also
been used, perhaps the German one does that.
The way in the future is possibly going to be through Shape Memory Alloys.
Some interesting research in these smart materials is being undertaken
at Cranfield University in UK, though not, I repeat NOT in the field
of "blindness". These are remarkable materials with applications to
many areas of assistive technology and responsive to very small
inputs of energy.
Cheers
