The Federal Communications Commission of the United States (FCC) has granted Google permission to use the Project Soli technology, which consists in controlling a mobile phone or any touch screen without having to touch it, thanks to the movement of gestures through the use of a radar.
The radar system is located on a small chip that uses the frequency band of 57- to 64-GHz, which is capable of recognizing hand gestures.
In a first phase Google plans to use Project Soli for smart watches, speakers and mobile phones. It should be noted that in 2015 the company had made this technology known.
