Sticking to BCI specifically and not other forms for biofeedback, most of those demos you see come from people with invasive, penetrative electrode arrays such as the Utah array. In some people, these sensors can enable a high level of control and performance (not Xbox controller level, but still Atari controller level which would be incredibly useful for people with Motor Neurone Disease). Unfortunately the body rejects them after a few months and they're back to square one.
To be honest with you, I don't think that the problem's intractable. Perhaps a clever materials engineer could develop a coating for the electrode arrays that the body accepts long-term and allows the user to train for years rather than months. Perhaps we could develop a new form of sensor altogether.
I don't know specifically what the answer is, but it won't come from the current paradigm of "turn garbage data into non-garbage output through the power of Machine Learning somehow" that we've been stuck in for the better part of two decades. And unfortunately, projects adhering to that paradigm is where all of the funding (and people) goes to.

A lot of support for this kind of stuff wrt EEF neurofeedback while ignoring the physics of what could be done with the raw data (if the PI actually understands or had a E&M class at least). Ppl in charge of getting the grants don't really care about the fact we do not gain any insight into whats going on when we use black box systems… oh well. I'd be happy to play around with biosemi 128 electrode cap+array + dsp + beamformers[0] and openemu[1] for two decades, deff not gonna happen in academia though.

- kodah 5y agoI did cognitive neurotherapy after a series of TBIs. The therapy seemed to work on me, though, what I've heard is that it's hit and miss. Of course, there's always the chance that I'd have recovered that way anyway, but given the state my academics were in I doubt it. For reference, the machine I used employed a bike game that supported movement across the screen. I eventually could make the bike go faster as well as up and down, nearly on command. It focused on alpha, beta, and theta waves measured by diodes stuck to your scalp. Not sure if that narrows that down, but I'm curious to know your thoughts.
