Point-of-Gaze Estimation: Theory and Applications Jeff Kang, Elias Guestrin, Moshe Eizenman, Erez Eizenman June 9, 2006

Point-of-Gaze Estimation Point-of-gaze: point in space imaged on the centre of the highest visual acuity region of the retina “Where we are looking” Motivation: Psychology/neurology: gaze follow shifts in attentional focus—gain insight into human cognitive processes Ophthalmology: objective measure of what is seen—measure the visual acuity of infants Human-machine interfaces: gaze-based pointing devices

Theoretical Foundation Measure position of eye features extracted from video images: pupil centre, corneal reflections

System Implementations Head- mounted Systems Remote Head-free Systems

Selected Applications Air Force Pilot Training Consumer Research

Quantification of Mood Disorders

Reading Behaviour

Research Directions Image Processing Adaptive algorithms Neural networks Current Projects Study of vision and reading disorders caused by brain lesions (Toronto Western Hospital) Development of vision tests for pre-verbal infants (Toronto Hospital for Sick Children) Development of reading aids for Age-related Macular Generation patients (University of Waterloo, School of Optometry)
