The idea of a stand alone screen reader hardware box with video input is
intreaguing and has
been tried by several folks including Dean Blazie. but that was years
ago.
I suspect actual screen text would be no problem, if perhaps a bit slow,
but
finding focus and defining/dealing with actual graphics could be a real
headache.
I think you'd need at least two processors, one to do the OCR and the
second
to run the screen reader and speech. Don't guess the Raspbery pi would
have
the "MIPS" for the ocr task.
BTW, the optacon actually connected to a mac's serial port and you could
read the screen directly with some kind of reader that Berkeley systems
had
as a prototype. the company died before it could be brought to full
operation <SAD>
For many years I kept seeing brags about optacon being restarted, but so
far as i know none ever came to reality.
