Hand gesture controls coming to a car near you?
How does it work? The system relies on an infrared sensor to "watch" for certain gestures. When it sees them, it passes a signal to separate processor, which in turn handles the connected hardware.
That sounds all well and good, but as anyone who's stood cursing at a motion-activated faucet in an airport restroom can tell you, these systems aren't foolproof. Fortunately, Harman says it won't have anything ready for market until it's been thoroughly tested, which may be up to three years from now.
