Buttons are so 21st century. BMW is presenting HoloActive Touch, an evolution of its Gesture Control system currently found in the flagship 7-Series sedans. Just wave your hands and a free-floating projection will mimic interactions like a physical touchscreen. It’s a concept you might remember from the 2002 sci-fi flick Minority Report in that, similar to a head-up display, a reflection makes an image appear to float in midair. A control pad appears next to the steering wheel on the center console and can be configured to perform various functions via finger gestures. A camera tracks the position of the driver's fingertips.
