Facebook shows off how youll use its neural wristbands with AR glasses

Facebook has offered a glimpse inside its plans for a new augmented reality interface, based on technology from CTRL-Labs, the startup it acquired in 2019. In a video, it shows off wristbands that use electromyography (EMG) to translate subtle neural signals into actions — like typing, swiping, or playing games like an archery simulator.
