In the risk of spreading misleading info, I just wanted to mention what I
was told, back in the 90's. The local dealer here, posed the info, that the
Optacon (second generation) was being manufactured by one of the mainstream
electronic brands. I am not sure if my memory serves me right, in recalling
which brand it was, but Panasonic was the name that popped out in my brain.
My point is, if this info is correct, the company who might have
manufactured the Optacon on behalf of TSI, might still be able to reproduce
the display of the Optacon. Just in case, any of this could bring us closer
to get hold of displays.
Would it maybe happen, that the old technology used in the original
displays, but being manufactured with modern materials, would overcome some
of the drawbacks. Give one comparison, with computer Braille displays. I
have two brands here, one being 5 years old, and the other being twice that
age, or so. Looking on the Braille cells and their physical construction, it
is quite similar in operation. But the newer display, is making use of newer
materials, and the cells are somehow reduced in size, and by far reduced in
operational noise.
Taking a look under the hood of an Optacon, I often wondered if the display
would have operated more quietly - simply by enclosing it with some kind of
sound absorbing material. Now aday, things like silicon or even neoprene
materials, can be quite sound absorbant even with relatively thin pads.
Just some ideas, as to the display challenge. Even if we could have got hold
of the original display manufacturer, there might have been chances that the
resolution of the display might be increased, without significant physical
size increase. Name me unrealistic, but something like 3 decades of
experience inside the electronic and technical work, and 4 decades of
experience inside assistive technology, gives the feeling that it is worth
the try. If for no other benefit, hopefully thoughts like this, will produce
new ideas, that in turn might just happen to lead to a break-through.
I guess my next idea - crazy as it is - already have been dealt with, long
time ago. But being new to the list, may I please ask, if anyone ever
contacted the old engineers of TSI, and asked if they could give out any
info to bring us further on. Look, maybe they could not do it ten years ago,
deue to patenting reasons or whatever. Maybe they will be more open about
things today. Just a crazy idea. Smile.
