Today (18/03), Facebook revealed two prototypes of smart bracelets that are capable of reading nerve impulses. The purpose of the new accessory from Mark Zuckerberg's company is to read impulses from the body to understand user commands with interaction with virtual and augmented reality glasses. The project is being developed by Facebook Reality Labs (the company's virtual and augmented reality research laboratory).

O Facebook states that “The wrist is a traditional place to wear a watch, which means it can fit reasonably well into everyday life and social contexts. It is a comfortable place to wear it all day long. It is located close to the main instruments you use to interact with the world (your hands). This proximity would allow us to bring the rich control capabilities of your hands to AR, enabling intuitive, powerful and satisfying interaction.”

The smart bracelet, in practice

The device uses technology that performs a type of electromyography, monitoring the electrical activity of two finger movements, translating this capture into digital information. The company hopes to improve the accessory in detecting nerve impulses, with a focus on using the object to fully control the virtual reality environment. The video below reveals a test of its functionality:

Another interesting video was also released, where the user moves his fingers, typing on an empty table. This way, the algorithms understand that he is typing according to the positioning of the keys. Of course, mistakes can happen, but with a type of spell checker, the user can change the words as the video itself reveals, check it out:
