Google’s Soli sensors has been approved by US regulators; a radar-based motion sensing device will be deployed, named as Soli Project. The US Federal Communications Commission (FCC) announced on Monday that it would allow Google to activate Soli sensors at power levels higher than those currently permitted.
Soli sensors use radar beams to capture motion in three-dimensional space, enabling non-contact control of functions or features. It can also be installed on aircraft. The FCC also said that this decision will serve the public by providing innovative device control using contactless gesture equipment.
As said by Google, the sensor allows the user to press a virtual button between the thumb and forefinger, or to spin the virtual dial by rubbing the index finger with the thumb. Although these controls are virtual, the contact between them is physically and sensitive, as feedback is produced by the touch of a finger. These sensors can be embedded in devices such as wearables, cell phones, computers and automobiles.
In 2015, Google demonstrated the Project Soli, which was very creative and new. Project Soli radar tracks movements in real time and uses your actions to change the signal. When you are still, your hands will actually move slightly, which becomes the benchmark for radar judgment signals. Keeping your hand away from the radar, or moving up and down or left and right will change the signal and its strength. Making a fist or crossing your fingers will also change the signal.
In March 2018, Google asked the FCC to grant its Soli radar to activate in the 57-64 ghz band, which meets the standards of the European Telecommunications Standards Institute. But Facebook expressed its concerns about Google’s radar to the FCC, saying that the Soli sensor works in higher power bands and may have issues coexisting with other new technologies.
After debate, Google and Facebook mutually informed the FCC in September that they decided that the Soli sensor could operate at a higher than currently allowed power level without interference, but below the level formerly projected by Google.
