Any sufficiently advanced technology is indistinguishable from magic. - Arthur C. Clarke

Facebook has unveiled a neural wristband that allows users to control augmented reality with their minds. The new interface is based on technology from CTRL-labs, the startup Facebook acquired in 2019. The project, which is still in the early stages of development, uses wrist-based electromyography (EMG) to translate neural signals into actions in an augmented reality (AR) or virtual reality (VR) setting.

According to a blog post published by Facebook Reality Labs, the band would let you type on a virtual keyboard with physical buttons faster than any physical keyboard could handle and perform the swiping gestures by thinking about moving your hands instead of actually moving them.

Facebook will be launching an AR headset this year and is planning to announce more details about its soft robotics research, all-day wearable devices, and additional developments on its haptic gloves later this year.
