Modeling eye movements in scene viewing
Visual attention controls most of the human behavior, being able to predict movements of attention would allow applications to anticipate the behaviors made in response to image content. We take a synergistic computational and behavioral approach for modeling the movements of human attention and predict the movements of human attention in various visual tasks: categorical visual search and free-viewing.

Modeling eye movements in web viewing
Web surfing is the most common activity to gain information these days. By leveraging gaze information during webpage viewing, we aim to systematically improve the Web user experience and accessibility.

Modeling eye movements in reading
A computational model of attention in the Superior Colliculus reading without a lexicon: Most models of eye-movement control during reading assume that saccadic behavior primarily reflects ongoing word-identification processing. We show, in contradiction with this view, that an image-based model of saccade programming in the superior colliculus (SC) can predict the highly stereotyped saccadic behavior observed during reading, simply by averaging early visual signals

Predicting cognitive/mental states from eye movements during reading: As the readers of a language, we all agree to move our eyes in about the same way. Yet might there be hidden within all this self-similar behavior subtle clues as to how a reader is engaging the material being read? We attempt to decode a reader’s eye movements using machine learning techniques to reveal their cognitive/mental states. e.g., level of text comprehension, difficulty and sleepiness.
