More Discriminating BCI for Robot or Computer Control

  Apparently - and this was news to me - most current production BCIs are mentally tiring for the user, because "do nothing" is actually something you have to keep thinking about, actively.  It's sort of like the Douglas Adams bit about a gesture-controlled radio interface that was eventually so sensitive you had to "sit infuriatingly still if you wanted to keep listening to the same program".  But since we're talking about the only means of mobility for some users, rather more serious.

  This one is more flexible in that it uses some statistical analysis to better catch commands (or "no command") even while other things are going on, like reading or speaking aloud.  Seems like a definite benefit!
