This document discusses Project Soli, a new technology being developed by Google that allows users to control their devices without touching them using gestures detected by small radar chips. Project Soli uses radar technology embedded in small chips to detect finger micro-motions and aims to allow intuitive control of computers, smartphones, wearables and gaming without touching screens. The technology is still in development stages and has not yet been released publicly but is expected to be made available to developers and potentially incorporated into consumer devices in the near future.
