Abstract

Gaze tracking can be divided into two-dimensional (2-D) gaze-estimation method and three-dimensional (3-D) gazeestimation method. 3-D gaze-estimation method can simplify user calibration and track gaze under full free head movement. To solve the shortage of traditional 3-D gaze-estimation method, this paper proposes a 3-D eyeball optical axis (OA) reconstruction method for single-camera multi-source head-mounted system. The method directly calculates the vector of the OA from the pupil image on the basis of the corneal center, and then reconstructs the eyeball OA. The results of simulation experiments show the effectiveness of the method.
