I wonder if the researchers know about Dasher and have considered combining the two interfaces to make text entry even faster? http://en.wikipedia.org/wiki/Dasher

Or is the issue that people with "locked-in" syndrome often can't even move their eyes? (If they could move their eyes, even a little, then surely an eye-tracking device would be a better interface - where a predefined movement, say, looking to the left twice, would count as a click.)

Seems like T9 would be a good match to this technology also.
