Drivers have depended on gestures to maneuver through traffic since the dawn of the automobile age, from a friendly wave to a shaking fist -- or worse.
Now, automakers are starting to use gestures to let drivers control functions of the car, whether it's an approaching hand to activate a dashboard infotainment system or the kick of a leg to open a crossover's tailgate.
Not only are the latest gesture technologies on display this week at the International CES here, but more will be featured at the North American International Auto Show in Detroit next week.
Hyundai plans to introduce a sleek concept car that incorporates "3-D gesture" control so a driver can operate an audio system with the wave of a hand.
