Meta researchers develop a generalized wrist that can interact with a computer

The researchers are the definition are Flaming development This allows people to control the computer with hand gestures. This includes moving the indicator, opening applications, and sending messages by writing in the air as if they were using a pencil.

Date wrinkle It uses a technique called surface electrical layout (SEMG)Which discovers the electrical signals resulting from muscle activity to explain the user’s movements, as shown in a research paper published in Nature. These signals can feel the intended person’s actions, even before they do.

The goal of this wrist is to provide less engraved tools to interact with computers for people with motor disabilities.

Company Cooperation with Carnegie Mellon To test the belt with people with spinal cord injuries, allowing them to use computers even if they cannot use their arms or their hands completely. Douglas Weber, a professor in the Department of Mechanical Engineering and the Institute of Neuroscience, noted that even people with full manual paralysis still show some muscle activity. As a result, the device is able to explain its intended actions.

The wrist is a simpler alternative to other projects, such as Elon Musk’s Neuzzallla, Which aims to plant brain chips in individuals with severe paralysis. Other non -invasive methods include headphones that use electrical planning signals (EEG); However, these restrictions are due to the weak signals they produce.

Meanwhile, the Meta wrist can be used immediately without surgical intervention, and its use of SEMG signals means that it works frequency above EEG.
