 Abstract: Most devices for eye- or gaze-tracking require constrained head and body movements in order to achieve high temporal and spatial accuracy, or a limited field of view or observer positions (eg for keeping the eyes visible for video tracking). This may lead to unnatural viewing conditions, possibly systematically altering gaze patterns in experiments. Furthermore, head and eye movements often cannot be analyzed independently. We present a novel system integrating high-speed eye- and head-tracking, thus enabling observers to move freely in front of large (wall-sized) displays. The system is modular, making it easy to track additional markers for body parts or pointing devices, if desired. Tracking is performed by an Eyelink II (500 Hz) and three Vicon MX motion capture cameras (180 Hz, erroramp;lt;1 mm), respectively. Gaze direction (based on independent eye and head direction) are calculated in real-time (erroramp;lt;0.8°, latencyamp;lt;6 ms), thus al lowing gaze- contingent d isplays. We present possible applications of the system in psychophysics and data visualization.
