[Sigia-l] eye tracking?

"People think that an eye tracker measures what a user sees. In fact, it

only measures what their eyes gaze at. There's a significant
difference."

Am I correct in assuming you are suggesting that without conscious
recognition information the eye takes has no impact?

So how do subliminal messages fit?  Are such messages just to
semantically impoverished to be relevant to information architecture or
user interface design?  

(my questions aren't related so much to eye track as to visual
communication generally).
