In general, that's what I've been trying to figure out: what
advantages does EEG actually give you, and in particular what are the
future prospects? I have had an absurdly hard time tracking down
predictions in the scholarly literature. There's absolutely nothing
that says "we predict an improvement of 10 to 50 wpm per
electrode/channel of data recovery". Now, typing might not be the best
application of EEG, and there's always the 6-axis arms to consider.
But that doesn't really excite me as much for some reason. At least
wpm is measurable performance metric.

Are there any EEG headsters on the list that can provide some PDF
files for me to read through? Here's what I've been reading in the
past few months:
