Google’s ‘Soli’ uses a small radar to detect touchless hand gestures


This article was 1st published on our sister Site, Digital World Native.

Soli is a tiny new sensor from Google’s Advanced Technology & Projects (ATA) group that uses miniature radar to track the human hand & detect touchless gesture interactions. The gestures detected by the sensor are based on familiar ‘virtual tools’ like opening with a key, pushing a button or turning a dial.

The sensor uses a next-gen control architecture that goes beyond what can typically be done by keyboards or touchscreens. It’s about the size of a dime, containing a sensor & antenna array in an 8mm x 10mm package. It emits a broad beam of electromagnetic waves & any object in the beam’s path, like your hand, reflects back to it, tracking things like time delay & frequency shift. This results in the recognition of dynamic gestures of the fingers & hand.
