Abstract
Gaze tracking is an important technique for human-computer interaction. A novel gaze tracking method with two lights and one camera is proposed, in which the similarity between spatial triangles is utilised to estimate the point-of-gaze, and a two-stage calibration is used to improve the estimation precision. Experiments show this method has low complexity, and its average gaze estimation error is about 0.7306° with a head movement range of 20 × 17 × 10 cm (width-height-depth).
