Meta shows a prototype of a bracelet without a screen that recognises "body language"

For several years now, Meta has been developing a screenless bracelet that relies entirely on data from the wrist, primarily gestures. Despite the long development, progress has been made and it is tangible.

The 2021 prototype had to be "taught" by showing certain movements so that the bracelet could adapt to the specific motor skills of a particular person. The current version of the bracelet uses a neural network. Despite the shorter training period, this has increased the number of movements that the bracelet recognises. The developers are proud of the fact that the bracelet now recognises not only the direction but also the strength of gestures.

The ability to recognise handwriting is impressive. According to Nature magazine, the bracelet can recognise writing at a speed of up to 20.9 words per minute.

By reading electrical impulses in the hand, the bracelet can understand the movements of the hand and transmit them to the computer, allowing you to move the cursor, "click" and interact with objects.

Why is this Meta?

We have no idea. The company does not report either the global goal of this development or even the commercial release of the device.

We can assume that such a device can help people with disabilities. Or it could become a game controller or manipulator for VR. Meta is developing the Meta Quest VR headset, so such an addition could extend the "immersion" in virtual reality.
