This doesn't seem like a neural interface at all. Yes, technically the device is measuring neural activity, but it's measuring neural activity in your arm, not in your brain. In effect, this seems to be way closer to gesture control than it is to a neural interface.
If that's all they're doing, the title of this post is very misleading (and consequently, most of the comments in this thread are irrelevant).
yep. it's totally a surface electromyography device that feeds into a neural network to recognize the gesture you are making from your wrist. There are alternatives of course, such as gesture recognition from a camera. This is interesting regardless, but wonder how useful it is. Gesture recognition is not new , it's just has not surpassed other input devices yet.
