Combined Head-Eye Tracking for Immersive Virtual

Abstract

Real-time gaze tracking is a promising interactiontechnique for virtual environments. Immersiveprojection-based virtual reality systems such as theCAVEallow users a wide range of natural movements. Unfortunately, most head and eye movementmeasurement techniques are of limited use during freehead and body motion. An improved head-eye trackingsystem is proposed and developed for use in immersiveapplications with free head motion. The system is basedupon a head-mounted video-based eye tracking systemand a ...
