  1. Point-of-Gaze Estimation: Theory and Applications Jeff Kang, Elias Guestrin, Moshe Eizenman, Erez Eizenman jeff.kang@utoronto.ca June 9, 2006

  2. 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

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

  4. System Implementations Remote Head-free Systems Head-mounted Systems

  5. Selected Applications Air Force Pilot Training Consumer Research
