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.<p>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.<p>What would RMS do if he had a choice between using a mobile phone with proprietary software to enable sight and remaining blind?
