I'm curious. Would some sort of intentionally-activated eye tracking work? Do your eyes have tremors?

Ideally (there's a pun in there, but it's not intentional) we could use our eyes to signal where we want our "focus" to be, but only when we want that signaling to happen. So a simple button held to indicate "track my eyes and focus on where I'm looking when I lift the button" might be useful.
