The acquisition of relevant information to maintain up-to-date users preferences is crucial in recommender systems in order to close the cycle of recommendations. Ambient Intelligence is a suitable approach to close the loop in nonintrusive way in recommender systems using ambient eye trackers. We combine a method to acquire relevance feedback through eye-tracking with functionalities of an extractor agent. We describe the results of experiments conducted in a recommender system to obtain implicit feedback using eye fixations. Finally, we obtain a ranking of users most relevant preferences and behaviours.
