I'm fortunate that I've never had rsi despite my extreme computer usage, but I'm interested in the possibilities of eye tracking for interfaces. Is it accurate enough? One simple thing that would come very handy is widget focus switching, maybe in combination with some key combo, "switch focus to where I'm looking" - that would save me a lot of reaching for the mouse.

At least at this point it's accurate to about a palm sized region, and there is a cool auto scroll demo. But getting together UI and making it useable is a pretty big project.

That's not great but it would be acceptable to switch focus between screens (or big enough tiles in a tiled desktop). Together with some clever mechanisms one could define task/tab/window groups per area and make switching much more manageable for large amounts of elements without having to surrender to "pick the mouse"-"select"-"back to the kb".
