Google's Project Soli could transform how we interact with wearables

SAN FRANCISCO — The group behind Google's Project Ara and Project Tango just revealed its latest experiment — and it could transform how we interact with smartwatches and other wearables.

Project Soli is a small, gesture-recognizing, radar-enabled sensor that aims to provide a way for people to interact with their smartwatches without touching their displays. The experimental project was introduced by ATAP, Google's Advanced technology and Projects group, during a session at the company's I/O developer conference Friday.
