1. A method for attention evaluation, comprising:
determining a region of interest (ROI) for an image displayed to a user;
receiving, via an image sensor, eye tracking information indicating an area of the image at which the user is gazing;
generating, via a processor, focus statistics based on the area of the image at which the user is gazing and the ROI, wherein the focus statistics indicate a first amount of time when the area of the image at which the user is gazing overlaps with the ROI, and a second amount of time when the area of the image at which the user is gazing does not overlap with the ROI;
determining an attention level based on the first amount of time and the second amount of time; and
outputting the attention level.
