A framework for polynomial model with head pose in low cost gaze estimation

This paper presents the framework for low-cost gaze estimation system to find the polynomial model used in with head pose based system. This framework uses three features - center of pupil, glint, and inner eye corner to create the polynomial model. The pupil-glint vector used to estimate eye gaze while glint-inner eye corner vector used to estimate head pose and adding inner eye corner to the model could improve the accuracy and robustness of the system. The framework consists of five steps ranging from data acquisition to testing the accuracy steps. This process introduces the validation method in order to prove the efficiency of the model.
