Hello:
If I were going to have a moving braille display, I think I would want detents
on the track. I would have the detent at each line. If I were designing a display,
I think I would rather have thumb switches across the front, like the Alva.
The advance bar would cause the dispaly to scroll one line. If the display had four
lines of braille, then the switch should be changable to scroll four lines at a time.
I would also have the display configurable for use with wide pages/screens.
Display options should include:
each line columns 1-40
each line columns 41-80
These are for looking at the left or right hald of a computer screen.
Line 1 columns 1-40
line 2 columns 41-80
etc.
Very wide lines would need to wrap around on more lines.
As for the largest rodent, the largest rodent in North America is the Beaver.
I think the Capabara, a native of South America is the largest rodent in the w0orld.
