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. Italians, known for an extravagant hand gesture or two, are not so sure.
A simplistic stereotype, but it captures the split among the world's drivers over the newest in-car tech on display at the Consumer Electronics Show in Las Vegas this week. Germany's BMW demonstrated a 7 Series car that recognises 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.
"It's certainly weird, certainly odd and certainly unproven. But Pioneer is not off base to connect one sensory organ to others," said Mark Boyadjis, an analyst at consulting firm IHS Automotive.
Given that drivers have enough to do keeping their hands on the wheel and eyes on the road, touch-free controls for some non-essential functions makes sense But it is not clear all drivers want gesture, eye-tracking or even lip-reading technology.
"The jury is out" on how widespread it will become, said Jeffrey Owens, chief technology officer for Delphi Automotive, which made BMW's gesture software.
The Japanese, some of the keenest consumers of novelty technology, are likely fans of Pioneer's 'bio-sensing system' that squirts out fragrance, said the company's marketing head Russ Johnston.
Enthusiastic visitors to Pioneer's booth at CES suggested cappuccino and peppermint as good wake-up smells, he said. The Japanese were the first to embrace back-up, or reversing, assistance because they did not want to bang their cars, said Guillaume Devauchelle, head of innovation at French auto parts supplier Valeo, who identified cultural preferences as a huge factor in adoption.
"There's no universal solution," said Devauchelle, whose company hired an ethnologist to make sense of different cultures with different tastes. He pointed out Germans' dislike of touchscreens, the risks of gesture control with expressive Italians, and the eager uptake of any kind of new tech by the Chinese, according to Reuters. -Mithun
