The days of staring at polygons on your GPS may be over. The guys at Electronista have unearthed details on TomTom's next generation GPS units. The new units will guide you using real-world images rather than 3D maps. The system would rely on a camera (mounted on the front of your car) to provide the live imagery to your GPS' display. Using image recognition technology, the unit would then pick out landmarks and sync it with the directions from your GPS. TomTom has filed a European patent on the idea, but there's still no word on how soon before we see it here.
