Audi is back at CES for the second year in a row, complete with a retina-searing, biggie-sized booth, its next-gen Audi Command interface and a prototype heads-up display that combines three displays with gesture controls.

The setup uses one HUD in front of the driver, another in front of the passenger and yet another display in the middle that's viewable by both people in the front seats. While that's not particularly revolutionary, the transfer of information from one display to the next is. If the passenger looks up a restaurant using their own display, she can swipe it over to the center HUD, providing the driver with navigation instructions. The display tech is still a few years away from production, but don't expect the gesture controls to come along for the ride.
