You know, this story in The Register really sums it up for me. This is what IT should be doing, empowering people to take back at least a portion of their lives and make them able to express themselves again. If I ever get a chance to do work like this, I'll love it and would do it for free. Well, maybe not for free, but I wouldn't want to earn a Porsche for it, just living off it would be nice too.
How cool would it feel to help someone in this way? Implement some electronics and have them use a computer. So many disciplines are needed to have it actually work, it's mind boggling. But the work would be so very rewarding. Since the guy can actually move and use a mouse, almost all things are available again (well, on a computer that is). What interface would he use? Looking at the site, I can see an IE sign, but they wouldn't use IE, right? The drawn monitor on the desk is a Mac, which would be a far better choice, since it much more mouse-orientated.
How would the guy in question experience the change? The psychological impact could be really large. I mean, bam! you loose the use of every single body-part except your brain and than all of a sudden, technology comes around to help you actually do something again. I imagine it would be euforic.
I hope noone around me every has to face such a challange, but if they do, I'll try as much as I can to help them implement these electronics. Have them do something again, even if it is just a game of Go. Cyberkinetics Inc., you guys rock.
