A little-known iPhone feature that lets blind people see with their fingers
I have mixed feelings about this. On one side, I'm very happy for blind people being enabled by software and hardware.On the other side, I'm concerned that people have to use proprietary software to enable their sight.  I doubt that there is open source software for blind people of similar quality.  Am I wrong?  I hope there is such software.What would RMS do if he had a choice between using a mobile phone with proprietary software to enable sight and remaining blind?
