There seems to be a quite widespread confusion regarding input and output devices when it comes to assistive technologies for the blind. I am being asked a lot how my "braille keyboard" works. Even by people from the tech industry. Thats when I typically gently explain that a good secretary doesn't need to look at their keyboard, the faster you type, the more you need to type blindly. Most assistive technologies for the blind are about output, and not about input... But it is frequently being confused.
