Real-time stereo tracking for head pose and gaze estimation

TLDR

Recent interest in computer systems that analyze human face/head motion focuses on real‑time head tracking and extending it to gaze estimation. The paper aims to develop a real‑time stereo vision system that determines a human subject’s head pose and gaze direction. The system uses real‑time stereo vision to compute head pose and gaze direction. The system achieves sufficient accuracy to support applications such as human‑computer interaction, consumer research, and ergonomic assessment.

Abstract

Computer systems which analyse human face/head motion have attracted significant attention recently as there are a number of interesting and useful applications. Not least among these is the goal of tracking the head in real time. A useful extension of this problem is to estimate the subject's gaze point in addition to his/her head pose. This paper describes a real-time stereo vision system which determines the head pose and gaze direction of a human subject. Its accuracy makes it useful for a number of applications including human/computer interaction, consumer research and ergonomic assessment.
