[gui-talk] Fwd: Press Release: New Cross WalkSafety System ForTheVisually Impaired

[Rafal Charlampowicz]

Interesting idea. Switching on the system from the cellular phone and the
alert seems great, but - I think - the accuracy of the GPS is a problem.
Perhaps installing on traffic lights receivers which would locate the person
crossing the street would increase the accuracy.
