point of gaze estimation
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
