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
