G.P.S. enabled travel guide
It’s like having a personal guide in hand. As the user moves around, it announces where he or she is. ‘Trekker’ is a small, lightweight device that uses the Global Positioning System (G.P.S.) to help visually impaired people find their way around. Along with G.P.S. technology, the device also uses talking digital maps and talking menus to provide real-time information on surroundings and also pinpoints user location.
