The whole 'swiping through panels' bit looks a lot like the way I work already: On OSX, my tendency is to full-screen all my apps, use the split-screen view for multi-tasking, and swipe between them all.

I'd have to wonder about the notion of tracking gaze: e.g. lack of on-screen visual feedback affirming that the device accurately knows what you're 'looking at/selecting' before you ask it to do something.

EDIT: I just noticed — six-finger gestures!?

tfw when yr Fullscreen gesture is Goatse.
