"Brain computer interface turns mental handwriting into text on screen," says the clickworthy headline from ScienceDaily. -- what stuck out from my first skim was that while the mechanics are fascinating, the output of text approached 90 words per minute, more than twice as fast as I can type. On second skim I read correctly 90 characters per minute. Oh well. The second take-home was that this could allow someone with motor-neuron impairments like ALS or a shut-in syndrome the ability to communicate more fluently than through a gaze-detector, eye-blink or cheek-twitch. The first few paragraphs: The Nature abstract is here. Like ScienceDaily, the journal's online DOI page is cheap with pictures. The video and image below comes from the Howard Hughes Medical Institute's report cribbed by ScienceDaily.
