Another possible design change: What if small pins, similar to those on
a braile display, were used. The noise factor would be eliminated, or at
least lessenet, and I wonder if the display would be easier to feel.
What if a camera could be designed to read and put a whole of line of
text into a momory at once? A slider switch could be moved back and
forth to feel the individual letters. I believe this kind of design
could bring about a lot of stability.
Another thing we might want to be thinking about is how could such
technologybe used to aid in reading GUI screens? How can we feel icons,
or is this really a practical use?
