There's a new iOS App in town that is literally taking those using VoiceOver, Apple's software screen reading solution for the blind and low vision, to the streets in a whole new way; and it's called Ariadne GPS. Join Mark on Saturday, July 23rd at 12:00pm (PDT) for a live conversation with the creator of Ariadne GPS, Mr. Giovanni Ciaffoni on the Secret Life of Mark Marcus Live talk show. During show time, call 724-898-1193 to participate or to just listen-in.
