AFAIK it is possible with training to control for instance a mouse pointer by based on thinking/imagining using you hand to move a mouse. Or something like that. But it does require training, I don't think you can do it on your first try. Which means that there's no well defined standard set of brainwaves for that specific task. If so, I can't see how tracking your brainwaves from the detector can be generally useful. Now. I won't exclude it a couple of years.
BTW, I'm guessing, but pibbuR hopes it's educated guessing.
PS. Regarding Win11, 3rd party seems to be you friend. And for the record, Win11 works very well for me, and I've had no problems installing/reinstalling it. OTOH, my experience with it is not that much different from number 10. So I while not regretting it, upgrading when I did was perhaps not necessary. However, there may for all I know be more significant changes under the hood - I'm sure there are watchers who know more about that than I do. And there is of course the question of support next autumn. DS
