FACEBOOK DEVELOPS NEURAL WRISTBANDS COMPATIBLE WITH AR GLASSES

Highlights
• Facebook in a recent video revealed wristbands that use EMG (electromyography) in order turn subtle neural signals into actions
• Facebook Reality Labs in a blogpost reveals more information on these neural wristbands
• The Mark Zuckerberg-led company said it has been implementing different prototypes that provide different types of haptic feedback

Social media giant Facebook has developed a new augmented reality interface, which is based on the technology developed by CTRL-Labs. CTRL-Labs, the startup it which was acquired by Facebook in the year 2019. Facebook in a recent video revealed wristbands that use EMG (electromyography) in order turn subtle neural signals into actions.
With these wristbands, one can type, swipe, play games or even an archery simulator. The wrist bands also feature haptic feedback, that allow users to ‘feel’ their actions, which currently are more responsive as compared to simple hand tracking.
Facebook Reality Labs in a blogpost reveals more information on these neural wristbands. These neural bands are able to track basic ‘clicks’, essentially touching your thumb and index finger together. Instead of a visual sensor, they will also track your nerve signals through your arms.
The Mark Zuckerberg-led company said it has been implementing different prototypes that provide different types of haptic feedback. These bands include ‘Bellowband’, which has eight pneumatic bellows around each wrist and these bellows inflate/deflate to produce distinct sensations, while ‘Tasbi’ on the other hand, uses vibrating actuators and a squeezing mechanism that relay signals to the users.
