When Google announced the Pixel 4, one of the main things they showed off was Motion Sense. These are air gestures using Google's proprietary Soli chip. It is basically a miniature radar chip built into the phone. At launch, it could control music by skipping tracks and it could detect when you were picking up the phone. With Android 11, released today as the first developer preview, Google has added a few new features including a play/pause gesture for controlling music.
