Way offtopic... computer interface using eyes only

Here's a video from a World of Tanks player in which he demonstrates a system for disabled people to use computers (in this case a video game) using only their eyes. They look at a menu bar and blink to select what's highlighted.

Just awesome when you think of people like Hawking or who have locked-in syndrome. Obviously it's most important use isn't for video games.

And, yes, I found this because I'm a WoT geek.

Here's a link in case the video isn't inserted.

That's really cool, Dave. I could definitely see the eye-movement sensor technology coming into play in lots of other incarnations and adaptations. Thanks for sharing!

PS: Something tells me your World of Tanks itch gets an even stronger scratch in those exceedingly rare instances when the Hawks go down.
