Tracking and Visualizing Visual Attention in Real 3D Space

Pfeiffer T. Tracking and Visualizing Visual Attention in Real 3D Space. In: Haack J, Wiese H, Abraham A, Chiarcos C, eds. Proceedings of the KogWis 2010. Potsdam: Universitätsverlag Potsdam; 2010: 220-221.Humans perceive, reason and act within a 3D environment. In empirical methods, however, researchers often restrict themselves to 2D, either in using 2D content or relying on 2D recordings for analysis, such as videos or 2D eye movements. Regarding, e.g., multimodal deixis, we address the open question of the morphology of the referential space (Butterworth and Itakura, 2000), For modeling the referential space of gaze pointing, precise knowledge about the target of our participants’ visual attention is crucial. To this ends, we developed methods to assess the location of the point of regard, which are outlined here
