raise-the-music

By Alexandria Sage LAS VEGAS (Reuters) – Germans love the latest wave of touch-free car controls, which respond to the flick of a wrist or the swipe of a hand, as it means no messy fingerprints on their spotless dashboards. Germany's BMW demonstrated a 7 Series car that recognizes five simple gestures, from a finger twirl to the right to raise the music volume and a hand swipe to decline an incoming call. Japan's Pioneer had a minty scent shoot out of a dashboard to revive a driver after a car seat sensor detected a falling heart rate, a possible prelude to nodding off.
