Paralyzed Patients "Speak" With Their Pupils
sciencehabit writes "Lying in bed, unable to move a muscle, so-called locked-in patients have few ways to communicate with the outside world. But researchers have now found a way to use the widening and narrowing of the pupils to send a message, potentially helping these patients break the silence. The trick is a webcam-like setup that tracks pupil dilation. When people focus on a hard problem--say a math problem--their pupils dilate. Employing the approach, some locked-in patients could answer 'yes' and 'no' questions just by dilating their eyes."
I mean, seriously, paralyzed people would probably be bad candidates for teaching anyone anyth...
OHHHHH. Those kinds of pupils!
I wish I had a kryptonite cross, because then you could keep Dracula and Superman away.
Why don't they go straight to neurofeedback? The hardware is getting a lot less expensive.
Technoli
With this type of tech, pretty soon we will be able to hook them all up to motorised boxes with a single light that can blink once for yes and twice for no.

I sincerely hope that by the time I might get to that state that the idiots who oppose euthanasia have been recognised as the nutjobs that they are and that I can be put out of my misery. If you kept a dog in that state (in the UK at least) you would be prosecuted for cruelty.
pupil dilation is more akin to peristalsis than blinking.
A bullet may have your name on it but splash damage is addressed "To whom it may concern."
Bullshit. It's real. My late wife had ALS, and her eyegaze computer was worth every penny. Even if it wasn't *HER* voice (we didn't bank it early enough), she could still talk with us.

Thank you for your feedback. I was actually hoping to hear someone with specific experience with these techniques share their impression of the technique.
Can you expand on your experience with this technique? How did it work in your late wife's case? What was the latency of the communication like due to the obvious bandwidth constraints of this particular medium?
