1. A method, comprising:
detecting presence of a user proximate to a refrigerator;
presenting one or more items contained in the refrigerator as visual stimuli displayed on a display of the refrigerator, the visual stimuli prompting a first physiological response from the user regarding the one or more items;
detecting and analyzing the user's first physiological response to the visual stimuli, wherein detecting the user's first physiological response comprises sensing the user's brainwave activity via at least one contactless brainwave sensor configured to wirelessly monitor the user's brainwave activity, and wherein the first physiological response comprises a visual evoked potential (VEP) response;
selecting an item of the one or more items based on analyzing the first physiological response to the visual stimuli;
measuring a second physiological response of the user to the visual stimuli via an ultrasonic transducer or a camera;
determining a level of interest of the user in the selected item based on the second physiological response; and
presenting, via the display of the refrigerator, targeted information regarding the selected one or more items based on the determined level of interest.
