As this year's Google I/O winds down, things are getting weird – in the coolest way possible. So far today we've been checking out some of the announcements to arrive from Google's bleeding-edge Advanced Technology and Projects division, where teams of engineers are cooking up tech that promises to change the way we interact with smartphones, and even think about how such handsets are made. Already we've told you about the upcoming launch of the first Project Ara hardware (finally!), as well as the touch-sensitive Levi Commuter smart jacket using Project Jacquard technology. Now we're taking a look at what the last year has done to advance Google's interest in radar-driven sensor technologies, as we check out an update on Project Soli, including some impressive demos from members of the Soli community.

The presence of radar hardware in a smartwatch allows the user to interact with the wearable without needing to make contact with its tiny touchscreen; instead of swiping right or left on its display, users can instead casually wave their hands back in forth in the air. It can even detect distance, expanding UI options as you bring your hand in closer, or respond to fine finger motion – like a hands-free pinch to zoom.
