Todd Lewis :
"What about having some gizzmo that watches where you are looking
on the screen and makes the mouse pointer follow that. Blinking
your left eye sends a left mouse button event, right eye is the
right button, and it would ignore (almost) simultanious left- and
right-eye events so you could still keep your eye balls from
drying out and falling out of your face. <+_*> |^)"
This is in fact possible. You can do it elecrophysiologically (I don't
recommend this, I used to do eyemovement research this way) or 'visually'.
There is a company in Australia which makes computer terminals for the physically challanged which track eyemovements as an imput device. I belive that they do it by proecting a circle of light towards the eyes, and measuring it's displacement and deformation wrt the centre of the pupil.
I always wanted to do this, cause it's kind of like magic, but I think I have a better idea now: use magnetoencephalography and a connectionist signal classifier to detect when someone is thinking certain words. I don't know that it work, but I certainly don't know that it wouldn't. scary - eh?
enough science fiction, back to fantasy.
