[BRLTTY] Pneumatic braille based on balls in a tube

[Devin Prater]

Well, how much will this device cost? And how long will it last? Please don't be like APH or Humanware. Will the device have braille keys on it? How many cells per line will it have? Will it be able to be used with a screen reader? Will it have USB or bluetooth or both? Will the "image arrangement" be able to have different hights per dots, to show color of the image or something like that? How will screen readers use this to show images? Will you help companies like Apple build this into their systems? If you use the sheet method, how would the sheets refresh themselves before being taken off the machine? How big will this thing even be? Will there be different sizes, like an 11 by 9 or however big normal print paper is? Or will you make a "mobile" and "desktop" version, or will there just be one big unit that can sort of fold into a smaller one for mobile use? And the most urgent question is, how much will the thing cost? $20? $200? $2000?
