US regulators approve Radar-based Hand Motion Sensor for Google

The deployment of a radar-based hand motion sensing device, Project Soli by Alphabet’s Google Unit, has been approved by the US regulators.

According to a report, the Federal Communications Commission (FCC) said that it would grant Google a waiver to operate the Soli sensors at higher power levels than currently allowed. The sensors can also be operated aboard aircraft, said FCC.

The FCC said the decision “will serve the public interest by providing for innovative device control features using touchless hand gesture technology.”

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.

Google says the virtual tools can approximate the precision of natural human hand motion and the sensor can be embedded in wearables, phones, computers and vehicles.

In March, 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.

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