What is Audi's gesture control feature and how does it work?

I've heard about Audi's gesture control feature, but I'm not sure how it works. Can someone explain it to me?

Audi's gesture control feature uses a 3D infrared camera to detect hand movements. This allows you to control certain functions, such as changing the volume or skipping songs, without having to physically touch any buttons on the dashboard.

I've been using the gesture control feature in my Audi A7 for a while now and I love it. It's a great way to avoid distracting yourself while driving. Just make sure to learn the proper hand gestures and practice in a safe environment before using it on the road.
