Meta has announced the release of its improved sEMG-RD bracelet, detailed in the journal Nature. This device captures electrical signals from muscles on the skin's surface, turning them into digital commands for navigating within a computer environment.

The latest prototype can automatically adapt to new users without extensive training, thanks to advanced neural network algorithms that quickly analyze signals and create a personalized control model.

Developers also showcased the ability to recognize gesture strength, paving the way for more complex interactions in virtual and augmented reality environments. The bracelet can even read handwritten text at a speed of 20.9 words per minute.

Meta has been working on such interfaces since 2021. The current version of the bracelet is one of the most promising developments in alternative control methods that do not require cameras or physical controllers. This solution may be particularly beneficial for users with disabilities.
