Real-time gaze tracking is a promising interaction
technique for virtual environments. Immersive
projection-based virtual reality systems such as the
allow users a wide range of natural movements.
Unfortunately, most head and eye movement
measurement techniques are of limited use during free
head and body motion. An improved head-eye tracking
system is proposed and developed for use in immersive
applications with free head motion. The system is based
upon a head-mounted video-based eye tracking system
and a hybrid ultrasound-inertial head tracking system.
