Abstract
A method for characterizing a sensory stimulation elicited by the presentation of a product, including the steps of: subjecting a human subject to visual stimulation, then to a sensory stimulation to be characterized, and to an image showing several emojis; acquiring and processing gaze tracking signals during the presentation of the image to determine a first emoji fixed for the longest duration, the latter determining a group of themes likely to be experienced during the sensory stimulation; and acquiring and processing physiological measurement signals during the visual stimulation and sensory stimulation to identify a theme experienced within the group of themes.

A method for determining a theme elicited by a product to be characterized, comprising the steps of:
- (a) presenting the product to be characterized to a human subject in such a way as to subject the subject to sensory stimulation;
- (b) acquiring physiological measurement signals from the subject before and during the presentation of the product to be characterized;
- (c) presenting to the subject an image showing a set of emojis during or after the presentation of the product to be characterized, the subject being asked to make a visual choice of emoji from the image;
- (d) acquiring eye tracking signals from the subject during the presentation of the image;
- (e) processing the gaze tracking signals to determine a first emoji number fixed for the longest duration by the subject, the longest duration fixed emoji determining a group of themes likely to be aroused in the subject by the presentation of the product to be characterized;
- and
- (f) processing the physiological measurement signals acquired before and during the presentation of the product to be characterized, to identify a theme aroused in the subject, within the determined group of themes.
