Luxury automaker BMW introduced its BMW Gesture Recognition feature at CES 2015. Currently in the "concept" stage, the system is set to be implemented into vehicles within the next year or two.
The new iDrive concept will add touchscreen capability to the LCD screen, as well as a camera that can recognize gestures from the driver, meaning that they can operate the system with a point of the finger. For instance, to answer a call, the driver merely needs to point to the "answer" icon. To decline an incoming call, the driver would brush their hand away in a "shoo-ing" motion. Similarly, to adjust the volume, the driver would move their finger in a clockwise or counter-clockwise motion.
The interface switches to a full number or keypad for entering numbers and addresses.
