This morning a friend of mine, Luca Reginato, who works at SrLabs in Padova sent me this very cool movie. Using a technology that they are developing, he tracked his eyes movements while browsing my weblog.

The blue spot you will see in the movie shows where he is looking, the larger the spot becomes, the longer he has been looking at a specific item. It's really amazing.

While today these services are available mainly to large companies (with large budgets), I'm trying to convince Luca that such a service made available at affordable prices would not only make sense, but be profitable. How much would you pay to have this kind of feed-back on a site you are designing or that you already have?
