Erich Sutter more than 20 years ago developed an amazing EEG BCI system
based on eye movements for ALS patients for whom eye movements were the only
motor output available. The patient would foveate a rich screen of letters
or words, each flickering with their own shifted pseudo-random orthogonal
m-sequence.

But without that foveation I don't know of any EEG based BCI system that
gives more than about 1 bit per second. If anyone knows of such a system it
would be good to post to this list.
