A method to facilitate and optimize performing a search for information in a database, the method comprising the steps of: presenting one item of data from a database at a time to an observer and measuring at least a physiological parameter of the observer; in the absence of any variation in the physiological parameter greater than a predetermined threshold, and if the observer does not make any particular remarks, presenting at least one other item of data to the observer and measuring the physiological parameter of the observer; in the presence of a variation in the physiological parameter greater than a predetermined threshold, detecting on an image at least one portion of interest to the observer and presenting an item of data having a relationship of similarity with the previously-presented data item, the relationship existing between the previously-presented image and the image presented after detecting a variation in the physiological parameter relating to said portion of interest; and repeating all previous steps until at least one item of data from the database, which contains said information, is identified.
