Google got a green light for producing sensors that would allow smart devices to be controlled only with the help of gestures.
Namely, the company is already working on Project Soli devices that contain sensors for detecting movement, and plans to implement them in smart devices. This way, smart devices and phones could be managed in the future via "invisible keys" that would be activated with gestures and certain finger movements. The device works by monitoring the movements in a three-dimensional space through the sensor, and then activating certain functions.
The Federal Communications Commission has finally issued a license for the project, and after several months of delay, and other companies have already expressed concerns that Google's new devices could endanger existing technologies.
