Brain-Computer Interface User Types 90 Characters per Minute with Mind
It seems like a direct brain-to-speech approach would make more sense for this application (communication from paralyzed people.)  This is sort of like trying to write with a theremin, eh?<p>I&#x27;m still on the far side with this, I know, but whenever these BCI stories go by I am bemused.  You connect a brain to a computer and then &quot;train a neural network&quot; on the computer side, that makes no sense.  The <i>sophisticated</i> NN is on the brain-side, yes?  With an integrated subjective UI already, yes?  You do not need fancy implants or hardware to &quot;talk&quot; to your machine, galvanic response and (now) micro-IMUs (inertial measurement units, one on each finger) are <i>plenty</i> of bits-per-second for a subjective Think-to-Type experience.  Use hypnosis, it&#x27;s easy, to program your brain to output a byte by changing the angle of your fingertips and then twitching the thumb to &quot;clock&quot; the data.  Or just standard stenotype, it would likely be easier, eh?<p>You don&#x27;t need fancy hardware or NN software (and especially surgery to stick electrodes in your brain) to &quot;talk&quot; to your machine with your mind, you already have all the technology you need &quot;built in&quot; to your nervous system.  It&#x27;s not even difficult to use.  Literally the first thing I learned to do when I was studying (self-)hypnosis was setting up a binary &quot;yes&#x2F;no&quot; signal (a finger twitch) from my unconscious mind to facilitate communication.<p>Anyhow, not to go on and on about it, the bottom line is when you connect a computer to a brain please remember that the <i>brain</i> is the fancier, more powerful &quot;device&quot;, okay?  You will waste less time.  (I am not sure why I am not able or willing to try to make something out of this.  I can talk to my computer well enough that I don&#x27;t bother with BCI.  ANd somehow the plight of these poor folks doesn&#x27;t move me enough to do something.  Am I a moral cretin?  I&#x27;m seriously you guys.  Should I try (harder) to get something going with simple hypnotic BCI systems?  HN?)
