I have used TextDetective on my iPhone to OCR a computer monitor a number of

Not as good of results as it would be from paper, but often enough to know 
what screen is displayed.

The Windows screen-reader NVDA has OCR built in.  It uses Tesseract to
OCR the screen.

The box said: 'install Windows XP, 7 or better'. So I installed Linux
