 Zusammenfassung: We present a mobile system for tracking the gaze of an observer in real-time as they move around freely and interact with a wall-sized display. The system
combines a head-mounted eye tracker with a mo-
tion capture system for tracking markers attached
to the eye tracker. Our open-source software library
libGaze provides routines for calibrating the sys-
tem and computing the viewer’s position and gaze
direction in real-time. The modular architecture of
our system supports simple replacement of each of
the main components with alternative technology.
We use the system to perform a psychophysical
user-study, designed to measure how users visually
explore large displays. We find that observers use
head move- ments during gaze shifts, even when
these are well within the range that can be com-
fortably reached by eye movements alone. This
suggests that free movement is important in nor-
mal gaze behaviour,motivating further applications
in which the tracked user is free to move.
