Nanodesktop Blind Assistant is a program that uses PSP to help blind people. This program is able to recognize names of people who are actually present in a room. In the future the authors will release a more complex version with a better speed of recognition and network support, along with support for GPS and “collision avoidance”.

It’s currently a PROOF OF CONCEPT program.
