Google has been granted permission to roll out wearable hand motion sensors that allow users to swipe, scroll and click their devices through thin air. Concern remains that the devices could interfere with other electronics.
The sensor technology, named Project Soli, has been in development since 2015. Worn on a user’s wrist, it allows the user to scroll, swipe, click and control their devices with simple hand gestures in the air. Users can click a virtual button between their thumb and index finger, or turn a virtual dial by rubbing these fingers together.
