Google has won approval from US regulators to build a Smartwatch that can be hand Gesture Control
It started work on Soli in 2015 but hit a roadblock because the Smartwatch was required to operate at lower power levels than the company planned. These restrictions are in place to stop new products from interfering with other (more important) technologies—in this case, radio astronomy, and satellite service.
How it Work:
Google says the Gesture Control of Smartwatch 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. In a video on its website, Google said a user could operate a smartwatch, scroll through music or adjust the volume by simply motioning using the system.
The company further added that the radar signal could penetrate fabrics, enabling controls that could work in a pocket or a backpack.
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.
Gesture Control could help users with mobility or speech impairments, Google said. But undoubtedly the novelty means it could win a wider audience. The FCC will also allow Soli sensors to be used on board aircraft.
