Google Wins US Approval for Radar-Based Hand Motion Sensor

Hand Motion Sensor

Alphabet Inc’s Google unit has gained approval from US regulators to set up a radar-based movement sensing device called Project Soli.

The Federal Communications Commission (FCC) announced that it would grant Google a waiver to operate the Soli detectors at higher energy levels than currently allowed. The FCC explained the sensors can also be operated aboard aircraft.

Further, the FCC said the decision “will serve the public interest by providing for innovative device control features using touchless hand gesture technology”, according to the sources.

The FCC said the Soli sensor captures motion in a three-dimensional space using a radar beam to enable touchless control of functions or features that can benefit users with mobility or speech impairments.

Google says the sensor can allow users to press an invisible button between the thumb and index fingers or a virtual dial that turns by rubbing a thumb against the index finger.

The company says that “even though these controls are virtual, the interactions feel physical and responsive” as feedback is generated by the haptic sensation of fingers touching.  The virtual tools can approximate the precision of natural human hand motion and the sensor can be embedded in wearables, phones, computers and vehicles.

Earlier In March 2018, Google asked the FCC to allow its short-range interactive motion-sensing Soli radar to operate in the 57- to 64-GHz frequency band at power levels consistent with European Telecommunications Standards Institute standards.

Facebook raised concerns with the FCC that the Soli sensors operating in the spectrum band at higher power levels might have issues coexisting with other technologies.

After discussions, Google and Facebook jointly told the FCC in September that they agreed the sensors could operate at higher than currently allowed power levels without interference but at lower levels than previously proposed by Google.

Facebook told the FCC in September that it expected a “variety of use cases to develop with respect to new radar devices, including Soli.”

The Soli devices can be operated aboard aircraft but must still comply with Federal Aviation Administration rules governing portable electronic devices.
