BMW will demonstrate at CES next week, a new “AirTouch” system, which uses hand motions and gestures to “operate like a touchscreen without actually having to make contact with the surface,” it announced.
Last year, BMW showed a gesture control system that made it into the new BMW 7 Series. This year, the company adds more control over the radio, navigation and communication. Sensors record the hand movements in the area between the center console and the rear view mirror. Users gesture and then they can confirm the gesture on steering wheel controls. Together the system reduces the number of steps needed to take an action.
