There is research work from the 1980's & 90's on the use of eye tracking for UI. Eyes tend to naturally scan around a scene - when the user becomes conscious that their gaze will 'affect' control regions in the UI they try to restrict this natural eye movement and it yields an uncomfortable sensation known as the 'Midas Effect'. This is mentioned and cited in this more recent paper: Real-Time Eye Gaze Tracking for Gaming Design and Consumer Electronics Systems Sorry I'm too lazy to extract the original citation... but it is worth tracking down and reading about how eye-gaze have been well known as a UI technique going back to the 1980's!

And I thought there were only three things that smelt of fish ... (one of them being fish, of course ... ;-)
C'mon we need to settle this before the nickname sticks ... ;-)
