[IxDA Discuss] Does eye-tracking carry any real meaning?(*edit)

[Mike Bennett]

For a brilliant example of the importance of attention in vision you  
should have a look at Prof Richard Wiseman's colour changing card trick:
           http://www.youtube.com/watch?v=voAntzB7EwE

Its a great illustration that just because your rentina "sees"  
something doesn't mean you will see it at a "cognitive" level.

BTW who spotted it? :)

There's a bunch of on-going research into visual attention - google  
will throw up lots of links (ah, if only google helped me understand  
it as well).
