This paper presents a system for real-time analysis of 3D gaze data arising in mobile applications. Our system allows users to freely move in a known 3D environment while their gaze is computed on arbitrarily shaped objects. The scanpath is analysed fully automatically using fixations and areas-of-interest – all in 3D and real time. Furthermore, the scanpath can be visualized in parallel in a 3D model of the environment. This enables to observe the scanning behaviour of a subject. We describe how this has been realized for a commercial off-the-shelf mobile eye tracker utilizing an inside-out tracking mechanism for head pose estimation. Moreover, we show examples of real gaze data collected in a museum.
