If the idea of someone playing with their phone while driving sounds distracting, then wait until you see the latest navigation concept from MIT and Volkswagen. Called the AIDA Project, this technology joint venture between MIT's SENSEable City Lab and VW stands for Affective, Intelligent Driving Agent.
Using a series of 3D projectors, a large map would take up residence in the unused space on top of the dashboard. Route guidance, destination information, infotainment options and a host of other features would all be controlled via hand gestures that are sensed by the AIDA 2.0 system.
This makes for very cool-looking tech, but we have to think Ray LaHood would plotz if this ever becomes reality. Also, we think the city of Boston may be virtual in the video demonstration due to the lack of middle fingers being tossed around as if they were Dunkin Donuts Munchkins.
