Google ATAP Soli
Jaime Lien and Nicholas Gillion wrote an interesting story for the Google AI blog about how their Soli radar-based perception features went from a chunky prototype in the company’s Advanced Technology and Projects (ATAP) lab to a tiny chip shipping in Pixel 4 phones. It involved a combination of creating and shipping a novel sensor, as well as designing machine learning models to power Motion Sense, the feature that recognizes hand gestures from radar data.
