Project Soli: Google's futuristic plan to replace buttons and touchscreens gets go-ahead

Google has received approval from US regulators to deploy a futuristic technology that allows smart devices to be controlled by hand gestures alone. The Federal Communications Commission (FCC) approved Project Soli, which was first announced by Google four years ago, saying that it would "serve the public interest" to push forward with development of the technology. The interactive control system uses radar-based motion sensors to detect and track hand movements with millimetre accuracy. This allows people to interact with devices without the need for any form of physical controls. The idea is that people will be able to control everything from TVs to smart watches in an intuitive, touch-free way.
