The last time I came across this topic, they tried to adapt the neural interface to control a computer for people with disabilities. You could type text, control the mouse, etc., well, such, rather primitive things. Probably now it has already developed into something more, but, unfortunately, I have already moved away from this topic.
Neurointerfaces allow processing human brain activity into teams. Therefore, the areas of application of neurointerfaces in the future can be very extensive - from computer games to weapons. At the moment, the most popular area is helping people with disabilities and rehabilitation after severe injuries.
