Braille displays use a static array, where, the vibratory nature of the
Optacon's array was the feature that allowed it to be used in a realtime
constantly
fluctuating environment such as that in which a human hand with it's natural
vagaries, moved a camera across some form of visually presented information.
Playing with technologies not mass-produced, or tested, costs money--lots of
money--and thereby makes bringing a replacement, or improved product to
market near-term less likely.

The reference to the mouse was an analogy. It was to give the idea something

handheld like a mouse.
Another point brought up is the array. It may be worth thinking of new
polymer technology and move away from piezo ceramic driven pins that are
bulky and heavy. I know there are developments in Braille displays using
polymers , but the refresh rate is currently a sticking point, but who
knows, if a research lab was involved in a new design, then perhaps this
limitation could be overcome.

I wonder if there would be a way of making the two pieces modular--for
one-handed or two-handed use. What would happen to the zoom lens? In my
picture, the camera is on the bottom and the array is on the top. In
Dave's description, the camera suddenly became a mouse.
I used the Optacon II screen-reading program for six years and that
program really did have a mouse. Rather than touching the actual monitor
with the CRT lens, the computer screen image was transferred to a
mousepad. If you were in a word processor, the image followed the cursor
and was controlled by the keyboard. Those poor arrrow keys got a lot of
use. Also, the program had an automatic scan. With a combination of mouse
buttons the program would read a whole line of screen or the whole page if
you wanted. The actile array was the same as always. Only the camera
method changed.
I'm still having trouble transferring the concept to a print page and
still protecting us form being subjected to pre-scanning. Again, I'm not
criticizing. I'm just confused.
