A user interface that combines eye tracking, voice, keyboard, and mouse input. I'm not sure what might work, but as something to explore/test: I look at a button and say "choose", and the button gets clicked. Or maybe I blink twice while looking at the button to click it. Or I say 'switch to Chrome' and it does so immediately, not after 10 seconds for a Siri round trip to Apple.

Eye gestures. Look at button, look left, look back at button.

Radial menus, like Maya. Look at button, menu appears, look in direction to open next menu, new radial menu appears.
