This article presents a gaze estimation method (GEMHSSO) based on the pupil center cornea reflection (PCCR) technique. Existing PCCR systems suffer from several problems, including the restriction of users’ head movement, and the requirement of individual calibration. This paper presents a head position compensation model using a single camera and a single light source, which realizes the analytic compensation of head motion effects on pupil-glint vectors. We then present a transformation model… CONTINUE READING
